Find the measure of <C in the following figure:

Yuki888 [10]

Answer:

angle C =160 degree

Step-by-step explanation:

since the given triangle is an isosceles triangle their base angles must be equal. So,

x - 10 =x/2

2(x - 10) =x

2x - 20 = x

2x - x = 20

x = 20

for angle B

x - 10

20 - 10

10 degree

for angle A

x/2

20/2

For angle c

angle A + angle B + angle C =180 degree (sum of interior angle of a triangle)

10 + 10 + angle C =180

20 + angle C =180

angle C =180 - 20

angle C =160 degree

Find the point estimate for the true difference between the given population means. Round your answer to three decimal places.

uranmaximum [27]

Answer:

Point Estimate for different between population means = - 0.99

Step-by-step explanation:

We are given data of two samples and we have to find the best point estimate of the true difference between two population means. Remember that in absence of data about population the best estimator is the sample data. So, we will find the means of both sample data and find the difference of that means. This difference between the means of sample data will be the best point estimate for the true difference between the population means.

Formula to calculate the mean is:

$Mean=\frac{\text{Sum of Values}}{\text{Number of Values}}$

Mean of Sample 1:

$Mean=\frac{1414}{11}=128.55$

Mean of Sample 2:

$Mean=\frac{1684}{13}=129.54$

Therefore the best point estimate for difference between two population means would be = Mean of Sample 1 - Mean of Sample 2

= 128.55 - 129.54

= - 0.99

$89.75 scooter; 7 1/4% tax

Kazeer [188]

If you are looking for the sales tax then you take 89.75 times .075 this will give you 6.73 now you just add 6.73 to 89.75 and you get..

sales tax = $96.48

but if you are looking for the %off you are going to do 89.75 minus 6.73 and you will get....

%off= $83.02

Use intercepts to graph the line described by each equation. -6y=-4x+24

Aloiza [94]

First, you have to get the equation to the normal form of a line. To do this, you divide both sides by -6 to get $\frac{2}{3} x-4$ . The y-intercept is at -4 and your slope is 2/3. Use this to graph the equation.
