Given that hypothesis test with

H_0:p=0.1 \\ H_a:p\neq0.1

where n = 480 and \hat{p}=0.12.

The test statistics is given by

z= \frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}  \\  \\ =\frac{0.12-0.1}{\sqrt{\frac{0.1(1-0.1)}{480}}} \\  \\ = \frac{0.02}{\sqrt{\frac{0.1(0.9)}{480}}} = \frac{0.02}{\sqrt{\frac{0.09}{480}}}  \\  \\ = \frac{0.02}{\sqrt{0.0001875}} = \frac{0.02}{0.0137}  \\  \\ =1.46

To solve this problem yo need to have the "x", the "y", and the radius. To find the radius since it is not given we use the formula.

sq rt(-3^2+1^2)

sq rt(9+1)

sq rt(10) would be the length of the radius in this case.

Then we use the sine cosine and tangent fractions

sin:y/r

cos:x/r

tan:y/x

With the values plugged in the equations are

SIN:1/sqrt(10) Since there can´t be a sq rt in hte denominator we change it to 1(sq rt(10))/10

COS:-3/sqrt(10) Since there can´t be a sq rt in the denominator we change it to -3(sq rt(10))/10

TAN:1/-3 This one can stay the same.

This would be the measures of SIN, COS, and TAN.

A ​used-droid dealership buys a droid for ​$2900 and then sells it for ​$4300. What is the percent​ increase?
Anna71 [15]

The percent increase is 48.28

Step-by-step explanation:

Given,

Purchase price of used-droid = $2900

Selling price of used=droid = $4300

Profit = Selling price - purchase price

Profit = 4300-2900 = $1400

Percent increase = \frac{Profit}{Purchase\ price}*100

Percent\ increase=\frac{1400}{2900}*100\\\\Percent\ increase=\frac{140000}{2900}\\\\Percent\ increase=48.275\%

Rounding off to nearest hundredth;

Percent increase = 48.28%

The percent increase is 48.28
