Answers

Answer:

6

Step-by-step explanation:

1/2 ^2 = 1/4

3/4 ÷ 1/5 = 15/4

9/4 + 15/4 = 24/4

2 − 10n = 2 + 4n
What does n equal?

Answers

Answer:

0 =n

Step-by-step explanation:

2 − 10n = 2 + 4n

Add 10n to each side

2 − 10n+10n = 2 + 4n+ 10n

2 = 2 + 16n

Subtract 2 from each side

2-2 = 2+16n-2

0 = 16n

Divide each side by 16

0/16 = 16n/16

0 =n

Answer:

n= 0

Step-by-step explanation:

Step 1- Add 10n to both sides.

2-10n= 2+4n

 +10n    +10n

2= 2+14n

Step 2- Subtract 2 to both sides.

2= 2+14n

-2  -2

0= 14n

Step 3- Divide both sides by 14.

0/14= 14n/14

n= 0

If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to *
100
0
1
10​

Answers

Answer:

10

Step-by-step explanation:

Coefficient of variation is a measure of dispersion, showing the variability of data in relation to the mean.

The Coefficient of variation compares the degree of variation between data points. The coefficient of variation is the ratio of mean to standard deviation. It is given by the formula:

Coefficient of variation = mean / standard deviation

Coefficient of variation = 50 / 5

Coefficient of variation = 10

Eli has 1500 clients at her hair salon. 15% of clients are children and 30% are men. The remaining clients are women. how many clients are children?

Answers

Given:

Eli has 1500 clients at her hair salon.

15% of clients are children and 30% are men.

To find:

The number of clients who are children.

Solution:

Total number of clients = 1500

Children clients = 15%

Number of children clients = 15% of Total clients

[tex]=\dfrac{15}{100}\times 1500[/tex]

[tex]=225[/tex]

Therefore, the total number of children clients is 225.

How to solve with steps.

Answers

A rule of thumb in these type of equations (at least, for me, personally) is to bracket off the like term. We’ve got 3 things here, so we gotta bracket them.
(5)+(10s-8s)
So now, we’ve got them separated. Next, we perform our given function. In this case, we subtract 8 from 10, leaving us with 2.
(5)+(2s)
As we no longer have any like terms, to be simplified or otherwise, we open the brackets:

What is the slope of a line perpendicular to the line y = -1/4x − 1?

Answers

Answer:

4

Step-by-step explanation:

The slope of a line that is perpendicular is the negative inverse of the original.  The slope of the given line is -1/4.  This means that the slope of the perpendicular line will be 4.

The slope of a line perpendicular to the line; y = -1/4x -1 is:. 4

The line y = -1/4x − 1 takes the slope-intercept form of a straight line; y = mx + c.

In essence, the slope of the line y = -1/4x − 1 is;

m1 = -1/4

Also, the slope of two perpendicular lines are related as follows;

m1m2 = -1

The slope of the line perpendicular to line y = -1/4x − 1 is therefore;

m2 = -1/(-1/4)

m2 = 4.

In essence, the slope of a line perpendicular to the line; y = -1/4x -1 is:. 4.

Answers

Answer:

5. 11.25 mi/hr

6. 24 hours

Step-by-step explanation:

5. The return trip at 9 mph took 5 hours.  So the distance is 45 miles.

The total distance traveled is therefore 90 miles, and the total time is 3 + 5 = 8 hours.

The average speed is distance divided by time, or (90 mi) / (8 hr) = 11.25 mi/hr

6. If t is the time it takes driving there, then t−4 is the time it takes to drive back.

Distance = speed × time, so the forward trip is 25t miles, and the return trip is 30(t−4) miles.  These distance are equal, so:

25t = 30(t−4)

25t = 30t − 120

120 = 5t

t = 24

Given that,
A relation is given we have to determine the domain and range of the relation.

What is the range?

Range, it is the set of values that come out to an outcome for a certain mathematical operation.

here,
A graph has been shown, over which there are multiple dot every dot represents a common relationship.
So, every abscissa of the point is an element of the domain of the relationship function, and every ordinate of the point is an element of the relationship function so,
Domain = {-4, 0, 2, 3}
Range = {-2, 2, 2, 4}

Answers

Answer:

The missing step is;

Add 8x to both sides of the inequality

Step-by-step explanation:

The step by step solution is presented as follows;

Step 1: Subtract 3 from both sides of the inequality

From the given inequality equation, we have;

5 - 8·x < 2·x + 3

Subtracting 3 from both sides of the inequality gives;

5 - 8·x - 3 < 2·x + 3 - 3

2 - 8·x < 2·x

Step 2: Subtract 8·x from both sides of the resulting inequality

2 - 8·x - 8·x < 2·x - 8·x

2 < -6·x

Step 3: Dividing both sides of the resulting inequality from above by the coefficient of x gives;

2/(-6) < -6·x/(-6)

-1/3 > x.
