Answer:

25 is 2.5 standard deviations from the mean.

Step-by-step explanation:

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean.

In this question:

Mean of 15 and a standard deviation of 4, so [tex]\mu = 15, \sigma = 4[/tex]

How many standard deviations from the mean is 25?

We have to find Z when [tex]X = 25[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{25 - 15}{4}[/tex]

[tex]Z = 2.5[/tex]

So 25 is 2.5 standard deviations from the mean.

Answer: [tex]\overline{IJ}\cong \overline{MN}[/tex]

Step-by-step explanation:

Given: In triangle HIJ and triangle MNO we have

[tex]\overline{HI}\cong \overline{NO}, \angle{I}\cong \angle{N} ,\angle{H}\cong \angle{O}[/tex]

here, HI and NN are the included side between  ∠I & ∠H and ∠N and ∠O.

So , by ASA congruence rule,

ΔHIJ ≅ ΔMNO

So by CPCTC  (corresponding parts of the congruent triangles are congruent)

[tex]\overline{IJ}\cong \overline{MN}[/tex]

Answer:

1) Irrational

2) Rational

3) Irrational

4) Rational

5) Rational

Step-by-step explanation:

A rational number is one that can be expressed as a ratio of 2 integers while an irrational number is one that can not be expressed like that. Another difference is that rational numbers can have finite or recurring decimals while irrational numbers have infinite and non - recurring decimals.

1) -20π is an irrational number because π contains infinite decimal digits

2) -26.23 is a rational number because it can be expressed as a ratio of 2 integers

3) -2√3 is an irrational number because √3 contains infinite decimal digits

4) -√1 is a rational number because √1 is a perfect square root and as such it can be expressed as a ratio of 2 integers.

5) 95.60 is a rational number because it can be expressed as a ratio of 2 integers

Answer:7

Step-by-step explanation:

Answer:

The number of cups of seeds that Sarah put in each bird feeder each day is:

= 4/7 or 0.57 cups.

Step-by-step explanation:

a) Data and Calculations:

Number of cups of seeds = 12 cups

Number of bird feeders = 3

Therefore, each bird feeder will get 12/3 = 4 cups per week

In a week, there are 7 days.

This implies that each bird feeder will get 4/7 cups

This is equivalent to 0.57 cups for each bird feeder per day.

b) Sarah will be putting 4/7 cups of seeds in each bird feeder.  When 4/7 is multiplied by 3 *7, we get a total of 12 cups, which represent the total number of cups of seed given initially to Sarah.

Answer:

The number of cups of seeds that Sarah put in each bird feeder each day is: = 4/7 or 0.57 cups.

Answer:

203 2/3

Step-by-step explanation:

Add all the wholes (55+55+46+46, that gets you 202), then, convert 2/3 to sixths (4/6). Then, add the fractions (4/6+4/6+1/6+1/6, that gets you 10/6, or 1 4/6). Now, our answer is 203 4/6, which can be simplified to 203 2/3.

Answer:

([tex]\frac{1}{2}[/tex], [tex]\frac{-1}{2}[/tex])

Step-by-step explanation:

Use the midpoint formula to solve.

1) Given 2 points: ([tex]x_{1}[/tex], [tex]y_1[/tex]) and ([tex]x_2[/tex], [tex]y_2[/tex])

The midpoint formula would be ([tex]\frac{x_1+x_2}{2}[/tex], [tex]\frac{y_1+y_2}{2}[/tex]).

2) Based on this, we can easily find the midpoint of AB.

3) With this information, we can solve for the midpoint.  

([tex]\frac{-3+4}{2}[/tex], [tex]\frac{-5+4}{2}[/tex]) --> ([tex]\frac{1}{2}[/tex], [tex]\frac{-1}{2}[/tex]) --> This is your answer.

Answer:↓↓

Step-by-step explanation:

2, 3, 13, 14, 16, 20, 20, 20, 30, 40

Mean: the average of a data set.

2 + 3 + 13 + 14 + 16 + 20 + 20 + 20 + 30 + 40 / 10 = 178/10 = 17.8

Median: the middle of the set of numbers.

16 + 20 / 2 = 36/2 = 18

Mode: the most common number in a data set.

20

Range: The difference of the smallest and highest number.

40 - 2 = 38

Answer: It increased by 78.89%

Step-by-step explanation:

2.810 / 3.562

=0.7889

78.89%

The approximate percent of change is 26.76% increase.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The average price for gasoline per gallon is $3.562.

last year the average price for gasoline per gallon was $2.810.

∴ The net amount change is  $(3.562 - 2.810) = $0.752.

Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,

= (0.752/2.810)×100%.

= 26.76% increase.
