Hank and Lynn are both paying off car loans. • Hank paid $2,000 upfront when he bought his car, and he pays $200 each month. • L

Naddik [55]

Answer:

the linkage between both the number of months and the amount charged is proportional to both loans from Hank and Lynn.

Step-by-step explanation:

The relationship between the number of months and the total cost paid proportionally is shown below:-

Both Hank and Lynn pay off car loans.

When Hank bought his car, he paid $2,000 in advance, and he needs to pay $200 each month.

Thus, forward to x months the total cost paid (C(h)) is

C(h) = 2000 + 200x ... (i)

So, that relationship is proportional, but not proportional directly.

When Lynn purchased her vehicle, she didn't pay any cash immediately front and she needs to pay $275 every month.

So, after x months the total amount paid (C(l)) is

C(l) = 275x ..... (ii)

This is, therefore, a direct proportionality that is also proportional.

Furthermore the linkage between both the number of months and the amount charged is proportional to both loans from Hank and Lynn.

Jason had $32. He spent all the money on buying 4 CDs for $x each and 2 magazines for $y each. If Jason had bought 5 CDs and 2 m

Leni [432]

You can set up two equations from the information given. I will set them up for you:

32 = 4x + 2y
36 = 5x + 2y

Let's solve the first equation to come up with a value for y.

32 = 4x + 2y
32 - 4x = 2y
16 - 2x = y

Now we plug y into the other equation.

36 = 5x + 2(16-2x)
36 = 5x + 32 - 4x
4 = x

Now we have our real x value and we can plug it into the first equation.

32 = 4(4) + 2y
32 = 16 + 2y
16 = 2y
8 = y

Since x = 4 and y = 8, you get the final coordinates of (4,8).

Your answer is the second statement provided above.

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed

OlgaM077 [116]

Answer:

Test is Left tailed test

Parameter tested is standard deviation

Step-by-step explanation:

We are given the hypothesis as;

Null hypothesis; H0: σ = 8.6

Alternative hypothesis; H1: σ < 8.6

Where;σ is a constant generally known in statistics as the standard deviation.

Now, it's the alternative hypothesis that will let us know whether this is left tailed, right tailed or two tailed.

Alternative hypothesis says σ < 8.6.

This means that the values of σ that satisfy this hypothesis are less than 8.6 and thus are on the left hand side of 8.6 on a number line. Thus, the shaded region in a normal distribution curve will be on the left.

Thus, it's a left tailed test
