Answer:

y = 3

Step-by-step explanation:

Since ABCD is similar to EFGH, therefore, the ratio of their corresponding sides are equal. Thus:

AB/EF = CD/GH

AB = 3

EF = 2

CD = 4.5

GH = y

Substitute

3/2 = 4.5/y

Cross multiply

3*y = 4.5*2

3y = 9

Divide both sides by 3

3y/3 = 9/3

y = 3

The graph shows the distribution of the number of text messages young adults send per day. The distribution is approximately Nor
erik [133]

The percentage of young adults send between 128 and 158 text messages per day is; 34%

<h3>How to find the percentage from z-score?</h3>

The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.

We are given;

Sample mean; x' = 158

Population mean; μ = 128

standard deviation; σ = 30

We want to find the area under the curve from x = 248 to x = 158.

where x is the number of text messages sent per day.

To find P(158 < x < 248), we will convert the score x = 158 to its corresponding z score as;

z = (x - μ)/σ

z = (158 - 128)/30

z = 30/30

z = 1

This tells us that the score x = 158 is exactly one standard deviation above the mean μ = 128.

From online p-value from z-score calculator, we have;

P-value = 0.34134 = 34%

Approximately 34% of the the population sends between 128 and 158 text messages per day.

The price for 7/8 of a pound of almonds is $6.65 . What is the cost of 3 and 1/2 pounds at the same rate?
Vlada [557]

The cost of 3 and 1/2 pounds of almond at the same rate is $26.60.

<h3>What is a fraction?</h3>

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In the illustration given as m/n, it should be noted that m is the numerator and n is the denominator.

Since the price for 7/8 of a pound of almonds is $6.65, the fraction per pound will be done by dividing the amount for a pound by 7/8.

= $6.65 ÷ 7/8

= $7.6

The cost of 3 and 1/2 pounds at the same rate is:

= 3 1/2 × $7.6

= $26.60

In conclusion, the cost is $26.60.
