Answer:

<h2>Second choice.</h2>

Step-by-step explanation:

The given inequality is

-\frac{1}{2}x \geq  4

Let's solve for x

x\leq -4(2)\\x\leq -8

Basically, the solution of the given inquality is set with all real numbers which are equal or less than -8. So, the solution must indicate a blue line starting at -8 pointing to its left.

Therefore, the second choice represents the solution to the given inequality.

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.

Openstudt what are the coordinates of the turning point for the function f(x) = (x − 2)3 + 1? (−2, −1) (−2, 1) (2, −1) (2, 1)
Dominik [7]

f(x) = (x - 2)^3 + 1

Find the derivative:-

f'(x) =   3(x -2)^2   This = 0 at the turning points:-

so 3(x - 2)^2 =  

giving x = 2 .  When x = 2     f(x)  =  3(2-2)^3 + 1 = 1

Answer is (2, 1)

From a sample with n=32, the mean duration of a geyser's eruption is 3.81 minutes and the standard deviation is 1.07 minutes. Us
Damm [24]
Notice that

1.67=3.81-2\times1.07
5.95=3.81+2\times1.07

This means you are looking for

\mathbb P(1.67

Chebyshev's theorem states that for any constant k>0,

\mathbb P(|X-\mu|

which means

\mathbb P(1.67

In other words, at least 75% of the geysers will have eruptions lasting between 1.67 and 5.95 minutes. Out of 32 geysers, then, one can expect at least 24 of them to have eruptions with between these durations.
