Answer:
I. Mean = 15
II. Median = 15
Step-by-step explanation:
Given the following data;
Total number of students = 8
x = 18, 10, 20, 18, 12, 19,12, 11
F(x) = 18 + 10 + 20 + 18 + 12 + 19 + 12 + 11
F(x) = 120
To find the mean;
Mean = F(x)/n
Mean = 120/8
Mean = 15
To find the median;
Median refers to the middle number of a sorted data.
x = 10, 11, 12, 12, 18, 18, 19, 20
Middle numbers = 12 and 18
Median = (12 + 18)/2
Median = 30/2
Median = 15

f(x)=-2(x+1)^2-12 in the form f(x) =ax^2+bx+c
Answer:
[tex] \boxed{ f(x) = -2x^2 - 4x - 14 } [/tex]
Step-by-step explanation:
f(x) = -2(x+1)²-12
f(x) = -2(x²+2x+1) - 12
f(x) = -2x² - 4x - 2 - 12
f(x) = -2x² - 4x - 14

An online furniture store sells chairs for $150 each and tables for $400 each. The store must sell a minimum of $4900 worth of chairs and tables each day. Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.
Answer: 150c + 400t ≥ 4900
Step-by-step explanation:
Let the number of chairs sold = c
Let the number of tables sold = t
Price for each chair = $150
Price for each table = $400
The inequality that could represent the number of tables and chairs sold will be:
(150 × c) + (400 × t) ≥ 4900
150c + 400t ≥ 4900

2. A submarine dives 60 meters in 5 minutes. Find how quickly it dives in feet per second (recall 1 meter = 3.28084 feet). How many feet can it dive in 6 minutes and 34 seconds?
Answer:
258.54 feet
Step-by-step explanation:
Step 1
We convert 60 meters to feet
1 meter = 3.28084 feet
60 meters = x
Cross Multiply
x = 60 × 3.28084 feet
x = 196.8504 feet
60 meters = 196.8504 feet
Step 2
How many feet can it dive in 6 minutes and 34 seconds
We convert 34 seconds to minutes
60 seconds = 1 minute
34 seconds = x
Cross Multiply
60 × x = 34 × 1
x = 34/60
x = 0.567 minutes
So, 6 minutes and 34 seconds = 6 + 0.567 minutes = 6.567 minutes.
60 meters in 5 minutes.
60 meters = 196.8504 feet
Hence:
5 minutes = 196.8504 feet
6.567 minutes = x
Cross Multiply
5x = 6.567 × 196.8504 feet
5x = 1292.7165768 feet
x = 1292.7165768/5
x = 258.54331536 feet
Approximately = 258.54 feet
Therefore, the submarine can dive 258.54 feet in 6 minutes 34 seconds

42.Anna pours herself some room-temperature soda from a bottle and adds four ice cubes. In a few minutes the ice cubes are smaller and the soda is much colder. Which of the following best explains the change in temperature of the soda?
A. Heat flowed from the soda to the ice cube and caused it to partially melt.
B. Coldness flowed from the ice cube to the soda, making the soda cooler.
C. The cold water from the melting ice went into the soda, replacing the warmer water that was in the soda
D. The water from the melting ice makes the soda more dilute, and the lower concentration makes the temperature lower.
and send me link for explenation
Answer:
Option A
Step-by-step explanation:
According to the second law of thermodynamics, heat always flows from hot to cold places, unless work is done on the system. In this case the ice is colder than room temperature, and therefore the heat flows from the soda to the ice cube. The ice cube absorbs the heat, and partially melts.
Find the Circumference area of the circle. Use 3.14 for pi. Round tithe nearest hundredth if necessary
Answer:
351.68cm
Step-by-step explanation:
Using the attached diagram
Radius of the circle = 56cm
Circumference of the circle =2πr
r is the radius of the circle
Circumference of the circle =2(3.14)(56)
Circumference of the circle = 6.28 *56
Circumference of the circle = 351.68cm
Hence the circumference area of the circle is 351.68cm

Assuming you're talking about the angles of a triangle, X would be [tex]34^{.}[/tex]
Step-by-step explanation:
The sum of the angles in a triangle is 180, 180 - 32 - 80 = 68, [tex]\frac{68}{2}[/tex] is 34, so X is equal to [tex]34^{.}[/tex].

A line segment has endpoints F(2, 2) and G(8, 2) Find the coordinates of its midpoint M
Answer:
(5,2)
Step-by-step explanation:
The midpoint of a line segment is calculated by finding the average of the x values and the average of the y values of the endpoints.
[tex]midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )[/tex] when the points given are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug points F(2,2) and G(8,2) into the equation
[tex]midpoint=(\frac{2+8}{2},\frac{2+2}{2} )\\midpoint=(\frac{10}{2},\frac{4}{2} )\\midpoint=(5,2)[/tex]
Therefore, the midpoint of the line segment with endpoints F and G is (5,2).

Answer:
26, 64
Step-by-step explanation:
we have :
angle 90°
acute angle x
acute angle 2(x+6)
The sum of the angles in a triangle has to be 180° so
90 +x+2(x+6) = 180
90 +x +2x+12 = 180
3x = 180 -90-12
x= 78/3 = 26°
the other acute angle is 2(26+6) = 64°
Answer:
26, 64
Step-by-step explanation:
We can name the first acute angle x and the second acute angle y. We know that x=2(y+6) but we also need another equation to solve the problem. Since we know that the sum of angles in a triangle is equal to 180 degrees and this is a right triangle, the two acute angles sum will be equal to 90 degrees. That would be our second equation, x+y=90. Now we can just substitute the first equation into the second one: 2(y+6)+y=90 -> 2y+12+y=90 ->3y=78 -> y=26
Now we can substitute y into one of the original equations and solve for x: x+26=90 -> x=64
