One, no, or infinitely many solutions?

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.

Step-by-step explanation:

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:

1st blank: 5

2nd blank: 10

3rd blank: 785

Step-by-step explanation:

the radius of a circle or the base/top of a cylinder is measured from the center to the side of the face, where as the diameter is measured from side to side through the middle, so the diameter will always be twice the radius of the same circle, meaning if the diameter is 10 units, then the radius will be half that, 5 units, then all we do is double the radius like the question says to get the height (NOTE this is NOT part of any formula for finding any dimensions for any shape and is specific to this question) then all we do to find the volume is use the formula below

V = (pi) (r^2) h

plug the radius or 'r' in as well as height or 'h' in the equation and solve

PLEASE NOTE: the question is asking for an APROXAMATE so your answer should be close to one of the drop down options by about >1 integer, but will not be exact

Good Luck!

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:

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:

12

Step-by-step explanation:

Since we can infer that those lines are the same length...

5x-15 = 3x+9

2x -15 = 9

2x = 24

x = 12

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:

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
