Use technology or a z-score table to answer the question.

1 answer:

7 0

121 of the green beans will be shorter than 13 centimeters.

First, we need to evaluate the expression below to find the z-score.
(13 - 11.2) / 2.1. = 0.86

The matching percent for this z-score is 0.8051.

Multiplying 0.8051 by 150 gives us about 121 green beans.

Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

$f(x)=A\cos (\frac{2\pi}{T}x)+b$

In the given case, you have:

A = 4

T = 3π/4

b = -3

By replacing you obtain:

$\begin{gathered} f(x)=4\cos (\frac{2\pi}{\frac{3\pi}{4}}x)-3 \\ f(x)=4\cos (\frac{8}{3}x)-3 \end{gathered}$

Hence, the answer is:

f(x) = 4cos(8/3 x) - 3

Determine the intercepts of the line. 7x-5=4y-67x−5=4y−67, x, minus, 5, equals, 4, y, minus, 6 xxx-intercept: \Big((left parenth

sesenic [268]

Given:

The equation of line is

$7x-5=4y-6$

To find:

The x and y-intercept of the given line.

Solution:

We have,

$7x-5=4y-6$

Putting x=0, we get

$7(0)-5=4y-6$

Add 6 on both sides.

$0-5+6=4y$

$1=4y$

Divide both sides by 4.

$\dfrac{1}{4}=y$

So, the y-intercept is $\left(0,\dfrac{1}{4}\right)$ .

Putting y=0 in given equation, we get

$7x-5=4(0)-6$

Add 5 on both sides.

$7x=-6+5$

$7x=-1$

Divide both sides by 7.

$x=\dfrac{-1}{7}$

So, the x-intercept is $\left(-\dfrac{1}{7},0\right)$ .

I'm not 100% sure what you're asking, but i think it wants:

50,000 + 25,000 = 75,000 - so B is the answer

to do it you basically just round the number to the nearest 1000 and add
