find the area of the shaded region of the radius is 9
Did I get the answer right

Answer:

x=80°

Step-by-step explanation:

Straight line=180°

therefore,

180=2x-30+50

minus 50 on both sides

130=2x-30

plus 30 on both sides

160=2x

divide 2 on both sides

x=80

Answer:

m∠A = 130

Step-by-step explanation:

Here, In a given figure

m∠A = 2x - 30°

Now, we know that the sum of all angle is 180° on a straight line

So,

2x - 30° + 50° = 180°

2x + 20° = 180°

2x = 180° - 20°

2x = 160°

x = 160° ÷ 2

x = 80°

Here, we get the value of x is 80°

Now,

m∠A = 2x - 30°

m∠A = 2(80°) - 30°

m∠A = 160° - 30°

m∠A = 130

Thus, m∠A = 130

Answer:

2 proportions z test

The two populations are named as residents from the first county and residents from the second county.

Step-by-step explanation:

This is testing hypothesis about the difference between two proportions.

When the proportions are tested if they are the test statistic

z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂

where p^1 is the proportion of success in the first sample and   p^2 of size n₁   is the proportion of success in the second sample of size n₂ with unknown proportions of successes p1 and p2 respectively.

When the sample sizes are sufficiently large

z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂ is approximately standard normal.

The two populations are named as residents from the first county and residents from the second county.

Answer:

The price of the TV with the sales tax included is $ 722.38.

Step-by-step explanation:

Given that a TV has a listed price of $ 671.98 before tax, and the sales tax rate is 7.5%, to find the total cost of the TV with sales tax included the following calculation must be performed:

671.98 + (671.98 x 0.075) = X

671.98 + 50.3985 = X

722.3785 = X

Therefore, the price of the TV with the sales tax included is $ 722.38.

Answer:

66.666%

Step-by-step explanation:

Ok first of all the first ticket is $3.00 the second one is 5.00. Important to note that the difference is $2.00. So we do $2.00/$3.00 which gives the answer of 66.666(recurring). Therefore your answer is 66.666%

Answer:

C

Step-by-step explanation:

The percentage of the shaded region of the circle is 75%.

Option C is the correct answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The circle can be in 4 parts.

Three parts are shaded.

Now,

The percent of the shaded region.

= (Shaded parts / Total parts) x 100

= 3/4 x 100

= 75%

Thus,

75% is shaded.

Answer:

The critical value that should be used is T = 2.492.

The 98% confidence interval for the population mean bromide concentration is between 0.486 cc/m³ and 0.518 cc/m³

Step-by-step explanation:

We have the standard deviation for the mean, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 25 - 1 = 24

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 2.492, which is the critical value that should be used.

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.492\frac{0.0313}{\sqrt{25}} = 0.016[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 0.502 - 0.016 = 0.486 cc/m³

The upper end of the interval is the sample mean added to M. So it is 0.502 + 0.016 = 0.518 cc/m³

The 98% confidence interval for the population mean bromide concentration is between 0.486 cc/m³ and 0.518 cc/m³
