Answer:

ok, first plot the point, 0, 4. that's your y intercept, it should be on the y axis. then count up one, then to the right four for your next point. the slope is 1/4, meaning that you rise 1 spot and move 4 spots. so your second point should be (4, 5) and your third point should be (6, 9) that's about it. if you need more help i can provide a better explanation

What sample size should be used if we would like to estimate the mean age of the college students at a particular campus with 95

nevsk [136]

Answer: 12

Step-by-step explanation:

The formula to find the sample size is given by:-

$n=(\dfrac{z_c\cdot \sigma}{E})^2$ , where $\sigma$ is the population standard deviation, $z_c$ is the z-value for the $(1-\alpha)$ confidence interval and E is the margin of error .

As per given , we have

Population standard deviation : $\sigma=5.1$

z-value for 95% confidence interval : $z_c=1.960$

Margin of error : E= 3

Then, the required minimum sample :-

$n=(\dfrac{(1.96)\cdot (5.1)}{3})^2\\\\\Rightarrow\ n=(3.332)^2=11.102224\approx12$

Hence, the required minimum sample size = 12

2. Your cousin is deciding whether to buy a car now or to wait until he has more

Delicious77 [7]

Answer:

option 2

Step-by-step explanation:

I'm using the assumption that he will have to pay for 4 years (as stated in the problem). You will need the length of time he would be making payments (in months) or the total cost of the vehicle to solve this problem.

4 years = 12 x 4 = 48 months

Option 1: 500 + 195 (48) = 500 + 9360 = 9,860

Option 2: 4,000 + 55 (48 - 6) = 4,000 + 55 (42) = 4,000 + 2310 = 6310

If he can wait six months, it will save him about $3,500 to go with Option 2.
