A shipping company selects 75 random packages to check their weight.It finds that 3 packages were weighed incorrectly. How many

Misha Larkins [42]

Answer: 120 Packages

Step-by-step explanation:

Given

75 random packages are check

3 package is found faulty

So, the percentage of error is

$\Rightarrow \dfrac{3}{75}\times 100=4\%$

i.e. 4% packages is faulty

For 3000 sample, expected faulty packages are

$\Rightarrow 3000\times \dfrac{4}{100}=120\ \text{Packages}$

4-9x= -14 solve the inequality.

polet [3.4K]

4 - 9x = -14
4 - 4 - 9x = -14 - 4
9/9x = -18/9
x = -2

PLEASE HELP!!! I don't understand it

Len [333]

Answer:

A

Step-by-step explanation:

This is exponential decay; the height of the ball is decreasing exponentially with each successive drop. It's not going down at a steady rate. If it was, this would be linear. But gravity doesn't work on things that way. If the ball was thrown up into the air, it would be parabolic; if the ball is dropped, the bounces are exponentially dropping in height. The form of this equation is

$y=a(b)^x$ , or in our case:

$A(n)=a(b)^{n-1}$ , where

a is the initial height of the ball and

b is the decimal amount the bounce decreases each time. For us:

a = 1.5 and

b = .74

Filling in,

$A(n)=1.5(.74)^{n-1}$

If ww want the height of the 6th bounce, n = 6. Filling that into the equation we already wrote for our model:

$A(6)=1.5(.74)^{6-1}$ which of course simplifies to

$A(6)=1.5(.74)^5$ which simplifies to

$A(6)=1.5(.22190066)$

So the height of the ball is that product.

A(6) = .33 cm

A is your answer

How do you change a percent to a decimal?

SSSSS [86.1K]

To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. Let's say we wanted to convert 82% to a decimal. We can think of 82% as the ratio 82 to 100 or 82 ÷ 100. When we divide by 100, it moves the decimal point 2 places to the left so 82 ÷ 100 would move the decimal point 2 places to the left which would give us .82. Therefore, 82% would = 0.82.
