Answer:

WRS=25 degree

Step-by-step explanation:

Angle VRT + angle TRS = 180 degree (supplementary angles)

5x+25x+30=180

5x+25x=180-30

30x=150

x=150/30=5

Substituting x=5 into angle VRT

5(5)=25

VRT= 25 degree

Looking at the diagram, angle VRT and angle WRS are vertically opposite angle and are therefore equal.

Now, angle WRS= 25 degree

Carlos and Ethan noticed that both proportional relationships and linear functions form a straight line when graphed. Carlos cla
Andrews [41]

Answer:

B. Ethan is correct because all proportional relationships form a straight line and go through the origin and linear functions are linear, but they don’t all go through the origin so they are not always proportional.

Step-by-step explanation:

So a proportional relationship is just a special kind of linear relationship, i.e., all proportional relationships are linear relationships (although not all linear relationships are proportional).

The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard devi
son4ous [18]

Answer:

Step-by-step explanation:

Since the length of time taken on the SAT for a group of students is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - u)/s

Where

x = length of time

u = mean time

s = standard deviation

From the information given,

u = 2.5 hours

s = 0.25 hours

We want to find the probability that the sample mean is between two hours and three hours.. It is expressed as

P(2 lesser than or equal to x lesser than or equal to 3)

For x = 2,

z = (2 - 2.5)/0.25 = - 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.02275

For x = 3,

z = (3 - 2.5)/0.25 = 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.97725

P(2 lesser than or equal to x lesser than or equal to 3)

= 0.97725 - 0.02275 = 0.9545
