Answer:

I'm pretty sure the Y position of the eyes is 70.

If the Variable Y is equal to 70, and the Y variable is where the Y axis value goes. Then the Y position of the eyes is equal to the Y variable which is 70. I think that makes sense, but feel free to comment if it does not so that I can help you figure it out.

If ƒ(x) = 2x, then ƒ -1(x) =<br><br> -2x<br> ½x<br> x - 2

Answer: second option

Step-by-step explanation:

To find the inverse function of the given function f(x):

$f(x)=2x$

You need to:

Substitute $f(x)=y$ into the function:

$y=2x$

Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:

$\frac{y}{2}=\frac{2x}{2}\\\\\frac{y}{2}=x$

Now, replace "x" with "y" and replace "y" with "x":

$\frac{x}{2}=y$

Therefore, substituting $y=f^{-1}(x)$ you get:

$f^{-1}(x)=\frac{x}{2}$ or $f^{-1}(x)=\frac{1}{2}x$

How do you solve (20.3×0.7)×7 with pemdas step by step

JulijaS [17]

TheProfessor35's answer is correct, but here's a step by step as you asked. PEMDAS stands from Parentheses Exponents Multiplication Division Addition Subtraction. So, in the problem, you first solve the part inside the parentheses. Are there exponents? No, so we move on. Anything need to be multiplied? Yes, 20.3 x 0.7. That gives us 14.21. Now, there is nothing left in the parentheses to be divided, added, or subtracted, so we move on to the outside. We multiply 14.21 by 7 and get 99.47.

A public relations firm found that only 27% of voters in a certain state are satisfied with their U.S. senators. How large a sam

OLga [1]

Answer:

a) 38

Step-by-step explanation:

The normal distribution can be applied if:

$np \geq 5$ and $n(1-p) \geq 5$

In this question:

$p = 0.27$

Then

a) 38

n = 38.

Then

38*0.27 = 10.26

38*0.73 = 27.74

Satisfies. But is this the smallest sample of the options which satisfies.

b) 14

n = 14

Then

14*0.23 = 3.22

14*0.77 = 10.78

Does not satisfy

c) 10

Smaller than 14, which also does not satisfy, so 10 does not satisfy.

d) 48

Greater than 38, which already satisfies. So the answer is a)

The perimeter of a rectangle is 354 km. Its side lengths are 81 km, 81 km, and 96 km. The fourth side length is given as "f" km.

k0ka [10]

The fourth side = f, now let's solve for f

f + 81 + 81 + 96 = 354

f + 258 = 354

f = 354 - 258

f = 96

value of fourth side = f = 96 km
