Answer: 9$

Explanation:

5 + 3 + 1 + x + 2 = 20

Subtract all those numbers

x = 9

5 + 3 + 1 + 9 + 2 = 20

20 / 5 = 4

Hello There!

For this one, like the other one, all we have to do is plug in the values

so

l 3 - (-2) + (-6) l

3 - (-2)

the two negative signs cancels out so now its

3+2 which is equal to 5

5-6=-1

l-1l remember l l means absolute value and the absolute value of -1 is 1 so the answer is 1

c) n -7

d). [tex]\frac{n}{7}[/tex]

Step-by-step explanation:

All you have to do for this question is look at the key words. These will help you find the correct answers.

Answer: D

Step-by-step explanation: The answer wouldn't be A because all the information is there, B is out because the question tells you there is a correlation between the two, and C is out because it has a more negative affect than positive.

Answer:B-70

Step-by-step explanation:

from the figure, In [tex]\triangle ABC\ \text{and}\ \triangle ADE[/tex]

[tex]\Rightarrow \dfrac{45}{45}=\dfrac{24}{24}\\\Rightarrow \dfrac{1}{1}=\dfrac{1}{1}[/tex]

[tex]\therefore \text{two triangles are similar}[/tex]

Thus we can write

[tex]\Rightarrow \dfrac{35}{x}=\dfrac{45}{45+45}\\\\\Rightarrow x=35\times \dfrac{90}{45}=35\times 2=70[/tex]

Answer:

29/40

Step-by-step explanation:

1/8 + 3/5 =

We need a common denominator.

8 = 2^3

5 = 5

8 and 5 have no common factors, so the LCD is their product.

LCD = 5 * 8 = 40

1/8 + 3/5 =

= 5/40 + 24/40

= 29/40

Answer:

$3.57

Answer:

a) 70,663.57< [tex]\overline x[/tex] < 113,680.43

b) The sampling distribution of the means is expected to be approximately normal given that n > 30

Step-by-step explanation:

The given parameter of the study are;

The number of reports in the study, n = 75 reports

The average debt, [tex]\overline x[/tex] = $92,172

The standard deviation, Sₓ = $111,538

a) A one-sample t confidence interval is given as follows;

The Degrees of Freedom, df = n - 1 = 75 - 1 = 74

[tex]C.I, = \overline x \pm t^* \cdot \dfrac{S_x}{\sqrt{n} }[/tex]

[tex]t^*[/tex] = The critical t, at 95% confidence level = 1.67

Therefore, we have;

[tex]C.I, = 92,172 \pm 1.67 \cdot \dfrac{111,538}{\sqrt{75} }[/tex]

Therefore, we have;

[tex]C.I, = 92,172 \pm 1.67 \cdot \dfrac{111,538}{\sqrt{75} }[/tex]

C.I. = (92,172 ± 21,508.43)

Therefore, the 95% one-sample t confidence interval for the average debt of the companies at the time of filing, C.I. = 70,663.57< [tex]\overline x[/tex] < 113,680.43

b) The defense for using the t confidence interval in the question is supported that the fact that the sample size is larger than 30 (n = 75) the sampling distribution of means will be approximately normal and the population mean will be between the confidence interval for the mean.

Answer:

Option C

Step-by-step explanation:

By the property of a rectangle,

"All interior angles of a rectangle measure 90°"

Therefore, m∠ABC = 90°

By applying cosine rule in the right triangle ABC,

cos(∠CAB) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(25°) = [tex]\frac{AB}{AC}[/tex]

AC = [tex]\frac{AB}{\text{cos}(25)}[/tex]

AC = [tex]\frac{18}{\text{cos}(25)}[/tex]

AC = 19.86

Therefore, Option C will be the answer.

Answer:

117π or 367.56634047

Step-by-step explanation:

Volume = π × r² × h          (r=radius and h=height)

Volume = π × 4² × 13

Volume = π × 9 × 13

Volume = π × 117

Volume = 117π

Answer:

Arranging the data in order,

3,5,5,7,8,9

The three numbers are missing.

Median = (9+1)/ 2

= 5

So the median is 5th term.

Median = 8

Answer:

 Median=8

Step-by-step explanation:

given numbers ⇒7,8,3,5,9 and 5.

Arrange numbers in order ⇒ 3,5,5,7,8,9

insert three numbers into the list

median will be highest 5 and the and 5 lowest on the list

If the three numbers are greater than 9 then the median be the highest

The median is the 5th item of data which is 8

median =8

Answer:

When two or more sperate ratios have the same value.

Answer and Step-by-step explanation:

Solve for x.

Distribute the 2.

4x - 5 = 4x - 2 - 3

Combine like terms

4x - 5 = 4x - 5

Add 5, and subtract 4x.

0 = 0

There are infinitely many solutions, meaning any value plugged in for x will result in the equation being true.

Answer:

Soleil and Malvin would have $ 5,000 all together after 13 days.

Step-by-step explanation:

Since Soleil and Malvin each work a job, and Soleil starts with $ 700 and makes $ 100 per day while Malvin starts out with $ 200 and makes $ 120 per day, to determine after how many days will they have at least $ 5000 all together it must be done the following calculation:

5,000 - 700 - 200 = 4,100

200X + 120X = 4,100

320X = 4,100

X = 4,100 / 320

X = 12.8

So Soleil and Malvin would have $ 5,000 all together after 13 days.
