Answer:
Selling price of each cap = £6.75 (Approx.)
Step-by-step explanation:
Given:
Number of caps = 500
Cost of caps = Rs. 200,000
Export tax = 5%
Profit = 150%
£ 1 = Rs. 155.63
Find:
Selling price of each cap
Computation:
Cost of 1 cap = 200,000 / 500
Cost of 1 cap = Rs 400
After Add export tax = 400 + 400(5%)
After Add export tax = Rs 420
After profit = 420 + 420(150%)
After profit = Rs 1050
Selling price of each cap = 1,050 / 155.63
Selling price of each cap = £6.75 (Approx.)

The side lengths of a triangle are 5, 3, and 4. Is this a right triangle?
A. Yes, because 32 +
*#2352
B. Yes, because 32 + 42 = 52,
O C. No, because 32 +42 + 52.
D. No, because 3+ 4+5.
Step-by-step explanation:
Given that,
The side lengths of a triangle are 5,3 and 4.
For a right triangle, the Pythagoras theorem is applicable. We know that, for a right triangle,
[tex]H^2=b^2+h^2[/tex]
Where
H is Hypotenuse
b is base
h is perpendicular height
If we put b = 3. h = 4, then
[tex]H^2=3^2+4^2\\\\H^2=9+16\\\\H=5[/tex]
Hence, it will form a right triangle.
If f(x) = 3x – 7 and g(x) = x2 – 5x + 5, then f(x) = g(x) for
what values of x?
a. x = 3 and x = 4
b. X = 6 and x = 2
c. x = -6 and x = -2
d. x = -3 and x = -4
Answer:
b
Step-by-step explanation:
3x - 7 = x² - 5x + 5
x² - 5x + 5 - 3x + 7 = 0
x² - 8x + 12 = 0
(x-6)(x-2)=0
x = 6
x = 2

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The zero of a function is a value of the independent variable (usually denoted as x) for which the value of the function (denoted as f(x)) is equal to zero.
In other words, the zero of a function is the value of x that makes the function equal to zero.
It is also known as a root or a solution of the function.
Geometrically, the zero of a function is the x-intercept of its graph, which is the point where the function crosses the x-axis.
Now,
From the function graph,
The graph has f(x) = y = 0 at the x = -5.
Thus,
The zero of the function represented by this graph is at x = -5.

Marvel use 864 beads to make necklaces for the art Club she made 24 necklaces with the beads if each necklace has the same amount of beads how many babies did Markle used to make each necklace
Answer:
I think the answer is 20736 beads?
Step-by-step explanation:
If the last sentence is supposed to say beads instead of babies, the answer is 20736 beads. This is because if u multiply the amount of beads used in one bracelet by the amount of bracelets, you should get the total amount of beads. So the two quantities are 864 and 24. If you multiply the two, then you get the total amount of 20736 beads.

Does Peyton Manning have a greater
passing ability in domes? After all,
inside a dome the weather is always
nice for throwing the ball! The
accompanying relative frequency
histograms show Manning’s 18 career
road performances inside a dome and
his 86 career performances outside
(through the 2010 season). In this
case, his performance is measured
with his passer rating, a combination
or passing yards, completion
percentage, number of touchdowns,
and number of interceptions. Only
road games are included because
Manning plays his home games in a dome and the benefit of playing in a dome would be impossible to separate
from the benefit of playing at home.
a. Briefly compare these distributions.
b. State the hypotheses we are interested in testing.
c. Manning’s mean passer rating in domes was 109.3 and his mean passer rating outside was 89.8, for a
difference (dome – outside) of 19.5. Describe how to simulate the distribution of this test statistic, assuming
that Manning’s ability is the same in both locations.
d. Here are the results of 100 trials of the simulation from part c. Describe what information is provided by the
dotplot.
e. Use the dotplot to estimate and interpret the p-value.
f. Using the p-value from part e, make an appropriate conclusion.
g. Is there is convincing evidence that Manning had a greater ability in domes, can we conclude that the dome is
the cause? Explain.
did u ever get the answers for it lol. i need help on it too
Answer:
ok so i had this for my stat class and i came on here to try and figure it out but didn't find any answers, so i just went ahead and tried it for myself. i'm not sure if i'm 100% correct, so if anyone knows the right answers leave a comment / post the right answers
ALSO my stat teacher gave us this exact assignment with these exact pictures so if ur gonna use these answers make sure you paraphrase them/reword them as best as you can
a) Briefly compare these distributions.
The distribution of passing ability for Manning’s passes in domes is relatively symmetrical while the distribution of his passes outside is skewed to the left. The distribution of outside performances varies slightly more than that of his performances within domes; outside performances vary from about 40-160 while performances in domes vary from about 60-160 (passer ratings).
b) State the hypotheses we are interested in testing.
H(o): Peyton Manning does not have a greater passing ability in domes than outside.
H(a): Peyton Manning has a greater passing ability in domes than outside.
c) Manning’s mean passer rating in domes was 109.3 and his mean passer rating outside was 89.8, for a difference (dome – outside) of 19.5. Describe how to simulate the distribution of this test statistic, assuming that Manning’s ability is the same in both locations.
1. Using 104 note cards, write each deviation on a different note card.
2. Shuffle the cards and divide them into two groups; one for passes outside, and one for passes within a dome.
3. Calculate and record the simulated difference (dome - outside) in standard deviation for the two types of pitches.
4. Repeat many times.
d. Here are the results of 100 trials of the simulation from part c. Describe what information is provided by the dotplot.
The dotplot illustrates the simulation repeated 100 times, with each dot representing a difference between the difference (dome - outside) for each individual simulation.
e) Use the dotplot to estimate and interpret the p-value.
Because there are no dots greater than or equal to our previously calculated difference of 19.5, the p-value = 0/100 = 0.
f) Using the p-value from part e, make an appropriate conclusion.
Since it is impossible (p = 0) to have a difference (dome - outside) in observed standard deviations of 19.5 or more by random chance alone when the true standard deviation of Manning’s passes was the same inside and outside a dome, there is convincing evidence that the true standard deviation of Manning’s passes was greater for his passes in a dome than outside a dome.
g) If there is convincing evidence that Manning had a greater ability in domes, can we conclude that the dome is the cause? Explain.
We can never 100% conclude that the dome is the primary cause of his better performance within domes. Other things like wind, crowd cheering, motivation, and teamwork could be some of the various causes of his better performance.

Use the equation: y = 5x - 4 Write an equation in any form) of a line that passes through the point (-1,7) and is parallel to the original line.
Answer:
y = 5x + 12
Step-by-step explanation:
Use the formula: y - y1 = m(x - x1)
Plug in all numbers into your equation: y - 7 = 5(x - -1)
Minus with a minus becomes a positive: y - 7 = 5(x + 1)
Distribute: y - 7 = 5x + 5
Add 7 to both sides: +7 +7
Answer: y = 5x + 12

For an experiment, a scientist needs 1/2 cup baking soda for 4/5 liter of water. Using this ratio, how much baking soda is needed for one liter of water?
Answer choices-
4/10 cup
5/8 cup
8/5 cups
10/4 cups
Answer:
5/8 cup of baking powder.
Step-by-step explanation:
Hence, using the ration given in the above question:
4/5 liter of water = 1/2 cup of baking soda
1 liter of water = x cup of baking powder
Cross Multiply
4/5 liter of water × x cup of baking powder = 1 liter of water × 1/2cup of baking powder
x cup of baking powder = 1 liter of water × 1/2cup of baking powder/4/5 liter of water
x cup of baking powder = 1/2 ÷ 4/5
x cup of baking powder = 1/2 × 5/4
x cup of baking powder = 5/8 cup of baking powder.
Therefore,
5/8 cup of baking soda is needed for one liter of water.
Please help me I really need it!!!! Find the midpoint of BD.
Answer:
The midpoint of [tex]\overline{BD}[/tex] is [tex](\frac{a}{2},\frac{a}{2})[/tex].
Step-by-step explanation:
Consider the provided information.
We need to find the midpoint of [tex]\overline{BD}[/tex].
For this, we will use the midpoint formula: [tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Now put [tex](x_1,y_1)=(0,a)[/tex] and [tex](x_2,y_2)=(a,0)[/tex] in the above formula and solve for M.
[tex]M=(\frac{0+a}{2},\frac{a+0}{2})[/tex]
[tex]M=(\frac{a}{2},\frac{a}{2})[/tex]
Hence, the midpoint of [tex]\overline{BD}[/tex] is [tex](\frac{a}{2},\frac{a}{2})[/tex].

Suppose x has a distribution with µ = 74 and σ = 8. If random samples of size n = 16 are selected, can we say anything about the x distribution of sample means?
Options :
No, the sample size is too small.
Yes, the x distribution is normal with mean μ x = 66 and σ x = 1.5.
Yes, the x distribution is normal with mean μ x = 66 and σ x = 6.
Yes, the x distribution is normal with mean μ x = 66 and σ x = 0.4.
Answer:
No, the sample size is too small.
Step-by-step explanation:
Given that:
Mean, μ = 74
Standard deviation, σ = 8
Sample size, n = 16
Based on the information given, in other to be able to make inference on the x distribution of sample means, then the size of the sample of utmost importance in statistic. Large sample sizes (usually > 30) gives are always required as sampling distribution conform to the population distribution Inn terms of mean as the sample size grows larger as the distributon becomes approximately normal.
However, the sample size given above is well below 30.hence, making it difficult to say anything about the distribution of sample means

Your student email account requires you to choose a password of 4 letters followed by one of the digits 0-9. The password can consist of upper case letters (26) or lower case letters (26).
How many different five-character passwords can be created?
Answer: 520
Step-by-step explanation:
Total choices for letters = upper case letters (26) + lower case letters (26).
= 26+26 = 52
Choices for digits = 10
By Fundamental counting principle,
The different five character passwords can be created = (Choices for letters) x (Choices for digits)
= 52 x 10
= 520
Hence, the number of different five character passwords can be created = 520
The Johnson family decides to take a trip to the theater over the holiday break. Theater tickets for adults cost $22. Children's tickets cost $15. 11 people went to see the play and the total cost was $228.
Let x= # of adults
Let y = # of children
Part A
Which equation represents the total number of people who went to see the play?
a.11x + 22 = 228
b.y = 15x + 11
c.22x + 15y = 228
d.x + y = 11
Part B
Which equation represents the total cost of the trip to the theater?
a.11x + 22 = 228
b.x + y = 11
c.y = 15x + 11
d.22x + 15y = 228
Answer:
a. 11 people went to see the play. the equation for the number of people who went is x + y = 11 because we don't know how many adults or children.
b. 22 dollars per adult, 15 dollars per child. since we don't know how many kids or how many adults, they're represented by x and y (as shown in part a)
the equation to represent the total cost is 22x + 15y =228 because the total cost to go was 228 and that's the only equation that has both variables and the total cost
