1.25

If you take the difference between two y axis numbers (say 5 and 10) which is 5 and the difference between two X axis numbers (say 4 and 8) which is 4. The y axis is the rise(5) and the x axis is the run(4). Using the formula rise/run (5/4) you can calculate the answer to be 1.25.

Please help me! I’m giving brainliest to whoever is right first
adelina 88 [10]

Answer:

y = 10

x = 17

Step-by-step explanation:

4y - 3 = 37

4y = 37 + 3

4y = 40

y = 40 / 4

y = 10

3x - 9 = 42

3x = 42 + 9

3x = 51

x = 51 / 3

x = 17

A student believes that less than 50% of students at his college receive financial aid. A random sample of 120 students was take
marusya05 [52]

Answer:

p= 0.9995 and we can conclude that students receiving aid is more than 50% according to the sample results in 2% significance level.

Step-by-step explanation:

H_{0}: less than or equal 50% of students at his college receive financial aid

H_{a}: more than 50% of students receive financial aid.

According to the nul hypothesis we assume a normal distribution with proportion 50%.

z-score of sample proportion can be calculated using the formula:

z=\frac{X-M}{\frac{s}{\sqrt{N} } } where

  • X is the sample proportion (0.65)
  • M is the null hypothesis proportion (0.5)
  • s is the standard deviation of the sample (\sqrt{0.5*(1-0.5)})
  • N is the sample size (120)

then z=\frac{0.65-0.50}{\frac{\sqrt{0.25}}{\sqrt{120} } } ≈ 3,29

thus p= 0.9995 and since p<0.02 (2%), we reject the null hypothesis.

Piper is deciding whether she should pursue an education in engineering or in public communications. She has researched that a p
arlik [135]

Answer:

A public communications director would make $1,196,800 over a period of 20 years.

Step-by-step explanation:

The median salary of an engineer is $73,400 per year.

Piper has researched that a public communications director makes $13,560 less than this. (so we need to take this amount from the salary of an engineer)

Therefore, we would have that a public communications director would make

73,400 - 13,560 = $59, 840 per year

Now, the problem asks us how much a public communications director will make over a period of <u>20 years</u>, thus, we have to multiply the amount she will get per year by 20.

Thus, over 20 years she would make: <u>59,840 x 20</u> = $1,196,800
