Find the value of x and y in the parallelogram below.

Delicious77 [7]

In a parallelogram, the opposite angles are equal and the sum of the angles is 360 degrees.

W = Z and Y = X
3y = 3x
Y = X = y
3y + y + 3x + x = 360
3x + x + 3x + x = 360
8x = 360
x = 360/8 = 45

Therefore, x = 45; y = 45

On a map,1/4 inch represents 16 actual miles.two towns that are 2 3/4 inches apart on this map are how many actual miles apart?

Alex73 [517]

Answer:

176 miles

Step-by-step explanation:

you have to know how many 1/4ths are in 2 3/4
4×2= 8 +3 = 11 so 11/4ths.
there are 11 , 1/4ths
determine the total mileage by multiplying 11 by 16
11×16=176
176 miles in total

A rectangular prism has a length of 13ft and a width of 16ft.

IrinaK [193]

Considering the volume of the rectangular prism, it is found that it's height is of 4.5 ft.

<h3>What is the volume of a rectangular prism?</h3>

The volume of a rectangular prism of length l, width w and height h is given by:

$V = lwh$

In this problem, the measures given are as follows:

l = 13 ft, w = 16 ft, V = 936 ft³.

Hence, the height, in ft, is found as follows:

$V = lwh$

$13 \times 16 \times h = 936$

$h = \frac{936}{13 \times 16}$

$h = 4.5$

George is curious. He has been told that the average body temperature of humans is 98.6 degrees Fahrenheit. However, he believes

nikitadnepr [17]

Answer:

The correct option is (B).

Step-by-step explanation:

In this case we need to test whether the average body temperature of humans is 98.6 degrees Fahrenheit.

The hypothesis can be defined as follows:

H₀: The average body temperature of humans is 98.6 degrees Fahrenheit, i.e. μ = 98.6.

Hₐ: The average body temperature of humans is less than 98.6 degrees Fahrenheit, i.e. μ < 98.6.

A random sample of n = 60 people are selected and their body temperatures are collected.

The population standard deviation is known to be, σ = 0.62.

As the population standard deviation is known, we will use the z-test for single mean.

The p-value of the test is, p-value = 0.0001.

We reject a hypothesis if the p-value of a statistic is lower than the level of significance α.

Here the p-value is very low. So, the null hypothesis will be rejected at any significance level.

Thus, there is enough evidence to conclude that the average body temperature of humans is less than 98.6 degrees Fahrenheit.

Thus, the correct option is (B).
