Two sides of a parallelogram are 730 feet and 970 feet. The measure of the angle between these sides is 151°. Find the area of the parallelogram to the nearest square foot.

Answers

Answer:

343294 feets

Step-by-step explanation:

We Obtian the height:

Using trigonometry :

Sin151 = h / 730

0.4848096 = h / 730

h = 353.91102

Area of parallelogram = base * height

Base = 970 feets ; height = 353.91102 feets

Area = 970 * 353.91102

= 343293.6894 feets

= 343294 feets

Given x = hypothenuse
10.8 = opposite
Degree = 57
You can use Sine (O/H)
Sin(57) = 10.8/x
0.8386705679 = 10.8/x
10.8 = 0.8386705679x
x = 10.8/0.836705679
x = 12.90776467 (round to tenth)

Solution: x = 12.9

A consumer advocacy group wants to determine whether there is a difference between the proportions of the two leading automobile models that need major repairs (more than $500) within two years of their purchase. A sample of 400 two-year owners of model 1 is contacted, and a sample of 500 two-year owners of model 2 is contacted. The numbers x1 and x2 of owners who report that their cars needed major repairs within the first two years are 53 and 78, respectively. What is the p-value of the appropriate test of hypotheses

Answers

Answer:

The answer is "0.3206".

Step-by-step explanation:

[tex]H_0: p_1 = p_2\\\\H_a: p_1 \neq p_2\\\\\hat{p_1} = \frac{X_1}{N_1} = \frac{53}{400} = 0.1325\\\\\hat{p_1}= \frac{X_2}{N_2} = \frac{78}{500}= 0.156\\\\\hat{p} = \frac{(X_1 + X_2)}{(N_1 + N_2)} = \frac{(53+78)}{(400+500)} = 0.1456[/tex]

Testing statistic:

[tex]z = \frac{(\hat{p_1}- \hat{p_2})}{\sqrt{(\hat{p} \times (1-\hat{p}) \times (\frac{1}{N_1} + \frac{1}{N_2}))}}[/tex]

[tex]=\frac{(0.1325-0.156)}{\sqrt{(0.1456\times (1-0.1456)\times (\frac{1}{400} + \frac{1}{500}))}}\\\\ = -0.99[/tex]

The area of the region under the curve of a function f(x) = ax + b on the interval [0, 4] is 16 square units.
(a, b) can't equal

Answers

The area of the given region under the curve of a function f(x) = ax + b on the interval [0, 4] is 16 square units. So, all the options satisfy the value of a and b except (7, -9).

How to find the area of a region?

Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly.

Then summing all those pieces' area gives us the area of the main big region.

The area of the given region under the curve of a function f(x) = ax + b on the interval [0, 4] is 16 square units.

f(x) is a linear function, the area under the curve on the interval [0,4] is a trapezoid with a height of 4 and bases of lengths f(0) and f(4).

The area of a trapezoid is the height times the average of the bases.

a. f(x)=-2x+8  f(0)=8, f(4)=0;

   area = 4(8/2) = 16

b. f(x)=x+2; f(0)=2, f(4)=6;

   area = 4(8/2) = 16

c. f(x)=3x-2; f(0)=-2, f(4)=10;

    area = 4(8/2) = 16

d. f(x)=5x-6; f(0)=-6, f(4)=14;

    area = 4(8/2) = 16

e. f(x)=7x-9; f(0)=-9, f(4)=19;

     area = 4(10/2) = 20

Thus, The area is NOT 16 for choice e.

The average score of 100 students taking a statistics final was 70 with a standard deviation of 7. Assuming a normal distribution, what test score separates the top 5% of the students from the lower 95% of students?

Step-by-step explanation:

We have,

The top percentage of the students is [tex]5\%[/tex]

The  lower percentage of the students is [tex]95\%[/tex]

The lowest [tex]95\%[/tex] is the left area from the normal distribution table, the area [tex]0.95[/tex] lies in the z-table

[tex]P(z<1.645)=0.95\\P(z>1.645)=0.05\\z>1.645[/tex]

Step-by-step explanation:

x³ + 10x² + 13x + 39 / x² + 2x + 1

To rewrite the above expression in the form q(x) + r(x) / b(x), we shall simply divide (x³ + 10x² + 13x + 39) by

(x² + 2x + 1)

Please see attached photo for explanation

From the attached photo,

the quotient q(x) = x + 8

The remainder r(x) = –4x + 31

Divisor b(x) = x² + 2x + 1

Thus,

x³ + 10x² + 13x + 39 / x² + 2x + 1

= (x + 8) + (–4x + 31) / (x² + 2x + 1)

Answers

Answer:

d. 90°

Step-by-step explanation:

Recall: based on the properties of a kite, the angles where the two unequal sides meet are congruent, this means that m<S = m<U.

Also, the sum of all angles of a kite = 360°

Therefore:

m<S + m<U + m<R + m<T = 360°

m<S = m<U = 80°

m<R = 110°

Substitute

80° + 80° + 110° + m<T = 360°

270° + m<T = 360°

Subtract 270° from each side

m<T = 360° - 270° = 90°
