Anyone know the area of the blue area?
Studentka2010 [4]
First, find the area of the larger sector (the 360-130=230 degree sector), then add the area of the triangle.
area of the larger sector:(230/360)π*11.1²≈247.17
area of the triangle when two sides and the angle between the two sides are given: (absinФ)/2. In this case, a=11.1, b=11.1, Ф=130
(11.1*11.1*sin130)/2≈47.19
the total area is 247.17+47.19≈294.4
Please use your calculator to double check my numbers.

Gwar [14]

Answer: 1 -2ax²+2x-ax

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Area of a rectangle: length x width

Replacing with the values given:

A = (2x+1) (1-ax)

A = [2x(1)] + [2x(-ax)] +[ 1(1)]+ [1 (-ax)]

A = 2x- 2ax² +1- ax

A = 1 -2ax²+2x-ax

In conclusion, the correct option is 1 -2ax²+2x-ax

Feel free to ask for more if needed or if you did not understand something.

The lifetimes of computer hard drives produced by hishobi company are normally distributed with a mean of 75 months and a standa
Mashutka [201]

The lifetime is months is 85.24 months

Step-by-step explanation:

In this question you are supposed to find the months "X' that is exceeded by 10% of the hard drives.

Exceeded by 10% means a value X on the frequency distribution table that is to the right of the mean score of 75 months showing 10% more.This means exceeding 10% will be months above 0.9 (from 100-90=90%=1-0.9=0.1 as a decimal)

In the standard normal distribution table, look for 0.9, closest value is 0.8997 which gives z=1.2 for y-axis and for x-axis 0.08 to give 1.28

So you have z=1.28, mean μ=75 and δ=8, finding X will gives

You apply the formula;

P(z>X-75/8)

P(z>1.28)=0.1

z=X-μ /δ

1.28=(X-75)/8

8*1.28=X-75

10.24=X-75

10.24+75=X

X=85.24 months
