What Is The Area Of The Shaded Region Below?7 M30 M7 M21 M

Answers

Answer 1

Answer:

322.28

A

Step-by-step explanation:

Area of the rectangle

L = 30

W = 21

Area = 30 * 21

Area = 630

Area of the circles

Radius = 7 m

Area = pi r^2

Area = 3.14 * 7^2

Area = 153.86 m^2

Area of both circles = 307.72

Area of the Shaded Region

Area of shaded region = area of the rectangle - area of 2 circles.

Area of Shaded Region = 630 - 307.72

Area of Shaded Region = 322.28

4. [tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

Step-by-step explanation:

1.

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

2.

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}[/tex]

[tex]m = \frac{3-2}{-2-2}[/tex]

[tex]m = \frac{1}{-4}[/tex]

[tex]m = -\frac{1}{4}[/tex]

3b.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

[tex]m = \frac{-1 - 2}{-1-0}[/tex]

[tex]m = \frac{-3}{-1}[/tex]

[tex]m = 3[/tex]

3c.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

[tex]m = \frac{1 - (-3)}{-1-4}\\[/tex]

[tex]m = \frac{4}{-5}\\[/tex]

[tex]m = -\frac{4}{5}[/tex]

[tex]r=\dfrac{PV}{nT}[/tex]

Step-by-step explanation:

The given equation is :

[tex]PV=nrT[/tex]

Where

P is pressure

V is volume

n is no of moles

r is Gas constant

T is temperature

We need to solve the above equation for r.

Dividing both sides of the above equation by (nT). So,

[tex]\dfrac{PV}{nT}=\dfrac{nrT}{nT}\\\\r=\dfrac{PV}{nT}[/tex]

So, the value of r is equal to [tex]\dfrac{PV}{nT}[/tex].

Determine the missing length in each right triangle using the Pythagorean theorem. Round the answer to the nearest tenth, if necessary.

Answers

Answer:

answer is 9 yd

Step-by-step explanation:

The missing length in right triangle by using the Pythagorean theorem is,

⇒ 9 yards

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

In a right triangle,

Hypotenuse = 15 yd

Perpendicular = 12 yd

Hence, By Pythagoras theorem;

Base² = 15² - 12²

Base² = 225 - 144

Base² = 81

Base = √81

Base = 9 yards

Thus, The missing length in right triangle by using the Pythagorean theorem is,

⇒ 9 yards

We are told that the data is representative of the two populations (U.S. males aged 20-29 years and U.S. males aged 75+ years), and we will assume that researchers collected random samples. The samples are very large; therefore, the conditions are met for use of the T-test. Using StatCrunch, we find a T-score of 5.3 and a P-value of "< 0.0001." What can we conclude? Group of answer choices The data prove that, in the U.S., young men weigh about 4.9 kgs more on average than old men. The data suggest that young men weigh more on average than old men in the U.S., but that the difference in mean weights for the two groups is not statistically significant. The data provide strong evidence that young men weigh more on average than old men in the U.S. no conclusion is possible because we did not specify a significance level

Answers

Answer:

The data provide strong evidence that young men weigh more on average than old men in the U.S

Step-by-step explanation:

Given :

The null hypothesis ; H0 : μ1 = μ2

The alternative hypothesis ; H1 : μ1 > μ2

T score = 5.3 ; Pvalue = < 0.0001

The decision region :

If Pvalue < α ; We reject the Null

If Pvalue > α ; We fail to reject the Null

When the α - level isn't stated, we usually assume a α - level of 5%

However, even at lower alpha level of 1% = 0.01 ;

The Pvalue < α

Hence, we can conclude that there is significant evidence that there is difference in the mean weight of young men and old men in the U.S

Jazzmine took out a loan of $17,500 to buy a new car. She received a 3.5% interest rate compounded annually and paid $3,274.50 in interest. How long did it take Jazzmine to pay off the loan?

Answers

Answer:

Time period = 5 year (Approx.)

Step-by-step explanation:

Given:

Amount of loan = $17,500

Rate of interest = 3.5% compounded annually

Amount paid as interest = $3,247.5

Find:

Time period

Computation:

Using compounded interest formula

I = P[(1+r)ⁿ - 1]

3,247.50 = 17,500[(1+3.5%)ⁿ - 1]

3,247.50 = 17,500[(1+0.035)ⁿ - 1]

3,247.50 = 17,500[(1.035)ⁿ - 1]

Time period = 4.948

Time period = 5 year (Approx.)
