Step-by-step explanation:

The congruence statement tells you that AC ≅ AE. AC is marked as 7, so ...

  AE = 7

_____

Additional comment

If you solve the triangle using the Law of Sines, you find that AC = AE = 6.484, not 7.

Answer:

$128,500

Step-by-step explanation:

Find out how much he will earn from his 1st year to 24th.

1st year = 48000

2nd year = 48000 + 3500 = 51500

3rd year = 51500 + 3500 = 55000

4th year = 55000 + 3500 = 58500

5th year = 58500 + 3500 = 62000

6th year = 62000 + 3500 = 65500

7th year = 65500 + 3500 = 69000

8th year = 69000 + 3500 = 72500

9th year = 72500 + 3500 = 76000

10th year = 76000 + 3500 = 79500

11th year = 79500 + 3500 = 83000

12th year = 83000 + 3500 = 86500

13th year = 86500 + 3500 = 90000

14th year = 90000 + 3500 = 93500

15th year = 93500 + 3500 = 97000

16th year = 97000 + 3500 = 100500

17th year = 100500 + 3500 = 104000

18th year = 104000 + 3500 = 107500

19th year = 107500 + 3500 = 111000

20th year = 111000 + 3500 = 114500

21st year = 114500 + 3500 = 118000

22nd year = 118000 + 3500 = 121500

23rd year = 121500 + 3500 = 125000

24th year = 125000 + 3500 = 128500

Answer:

(5.5,2)

Step-by-step explanation:

Find the midpoint of the segment with the following endpoints (7-6) and (4-10)

The formula for calculating the x and y coordinate is expressed as

X = x1+x2/2

X = 7+4/2

X = 11/2

X = 5.5

Y = y1+y2/2

Y = -6+10/2

Y = 4/2

Y = 2

Hence the required midpoint is at (5.5,2)

Answer:

189/8 cm^3

Step-by-step explanation:

Given data

Base= 7/2 cm

Hieght= 3/2cm

Length= 9/2cm

We know that the expression for volume is

Volume = L*B*H

substitute our data

Volume= 7/2*3/2*9/2

Volume= 189/8 cm^3

Hence the volume is 189/8 cm^3

Answer:

First question: LCL = 522, UCL = 1000.5

Second question: A sample size no smaller than 418 is needed.

Step-by-step explanation:

First question:

Lower bound:

0.36 of 1450. So

0.36*1450 = 522

Upper bound:

0.69 of 1450. So

0.69*1450 = 1000.5

LCL = 522, UCL = 1000.5

Second question:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

The project manager believes that p will turn out to be approximately 0.11.

This means that [tex]\pi = 0.11[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The project manager wants to estimate the proportion to within 0.03

This means that the sample size needed is given by n, and n is found when M = 0.03. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{0.11*0.89}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.11*0.89}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.11*0.89}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.11*0.89}}{0.03})^2[/tex]

[tex]n = 417.9[/tex]

Rounding up

A sample size no smaller than 418 is needed.

Answer:

98 degrees

Step-by-step explanation:

HJ = (5x - 7)

Because it's a full circle:

61 + 34 + (5x - 7) + (9x - 22) = 360

95 + (14x - 29) = 360

14x = 360 - 95 + 29 = 294

x = 21

HJ = 5x - 7 = 5 * 21 - 7 = 105 - 7 = 98

Answer:

Area = 452.16 cm²

Volume = 904.32 cm³

Step-by-step explanation:

The solid is a sphere, therefore,

Volume = ⁴/3πr³

Where,

π = 3.14

r = 6 cm

Volume = ⁴/3*3.14*6³

Volume = 904.319997 ≈ 904.32 cm³ (nearest hundredth)

Area = 4πr²

Area = 4*3.14*6²

Area = 452.16 cm²

Answer:

500 feet below sea level

Step-by-step explanation:

You would take 2,500 and subtract 3,000 feet giving you an answer of -500 feet. Which means it is 500 feet below sea level

Answer:

x=42

Step-by-step explanation:

Write the equation.

2(x+50)=16+4x

Spread the parentheses

2x+100=16+4x

Put variables on one side, numbers on the other.

2x-4x=16-100

Add/subtract/multiply/divide the variables with variables and numbers with numbers.

-2x=-84

Make x alone

-x=-42

Flip sides to make x positive

42=x

Answer:

75%

Step-by-step explanation:

Answer:

75%

Step-by-step explanation:

In a box-and-whisker plot, the whiskers show the minimum and maximum while the edges of the box show the first and third quartiles. The line in the box shows the median.

Quartile means a quarter of the data.

We're trying to find out what percentage of the students scored between 70 and 100.

70 is right on the 1st quartile mark, while 100 is on the maximum mark.

This means that a quarter of students got lower than 70, and nobody scored over 100 (because it's a test and it's calculated in percentage).

If a quarter of students got lower than 70, that means three-quarters of students got 70 or higher. And since the maximum is 100, and that is also what we're trying to find, the answer is 3/4 of all students.

3/4 = 75%

Hence, the answer is 75%.

Answer:

x=7/2 and x=-2/7

Step-by-step explanation:

By the Zero Product Property, we will set both expressions equal to 0 and solve:

p(x) = (2x-7)(7x+2)

0 = (2x-7)(7x+2)

2x-7=0 and 7x+2=0

2x=7 and 7x=-2

x=7/2 and x=-2/7

The factors of the polynomial are (2x – 7) and (7x + 2). Then the zeroes will be 7/2 and negative 2/7.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The polynomial is given below.

p(x) = (2x – 7)(7x + 2)

Then the zeroes of the polynomial will be

The factor of the polynomial is already given. Then the zeroes will be

x = 7/2, -2/7
