Answer:24/3/7/5 = 8/ 35 ≅ 0.2285714

Step-by-step explanation:

Divide: 24/3: 7 = 24/3· 1/7

= 24 · 1/3 · 7

= 24/21

= 3 · 8/3 · 7= 8/7

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 7/1 is 1/7) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, cancel by a common factor of 3 gives 8/

7

.

In other words - twenty-four thirds divided by seven = eight sevenths.

Divide: the result of step No. 1 : 5 = 8/7 : 5 = 8/7 · 1/5

= 8 · 1/7 · 5

= 8/35

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 5/1

is 1/5

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - eight-sevenths divided by five = eight thirty-fifths.

Answer:

First we must distribute the 2.6 to everything inside the ()

The new equation would then be 14.3p-32.24 = 127.92

Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel.

The new equation would then be 14.3p = 160.16

Then you divide each side of the = by 14.3, that way the p becomes isolated. 14.3p/14.3 = 160.16/14.3

Then you're left with p=11.2

Answer:

48

Step-by-step explanation:

To calculate the area of a composite shape you must divide the shape into rectangles, triangles, or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes.

I split it into a square and a trapezoid

The area of the square is 6x5 = 30

The area of the trapezoid is

A=a+b

2h=3+6

2·4=18

So add the area together

30+18= 48

Answer:

Explanatory variable (independent variable)

Response variable (dependent variable)

(a) As the class wondered if they could predict the father's height, when they know the son's height

Explanatory variable = son's height

Response variable = father's height

(even though this is contrary to real-life, where the father's height would be used to predict the son's height)

(b) **see first attachment**

(c)  The association is positive since the father's height increases as the son's height increases.

(d)  **see second attachment**

Outlier = Paul  (64.5, 73)

This point is far away from the majority of points on the scatter plot.

If we add a regression line to the scatter plot, we can see that this data point is the farthest from the regression line.

Answer:

115.395 min

Step-by-step explanation:

First we find the volume of 6 cm of water. We use the formula:

[tex]\pi *radius^2 *height[/tex]

[tex]\pi *35^2*6 = 23,079 cm^3[/tex]

1 L/min = 1000 cm^3 / min

0.2 L/min = 200 cm^3 /min

The speed at which Erin drove from the given parameters was calculated as; 35 mph

Let Erin's speed rate be X. Now, since it took erin 21 miles, then;

Erin's time = 21/X

Now, erin's speed was 10 mph faster than Brent's speed. Thus;

Brent's speed = (X - 10) mph

Thus, Brents time = 15/(x - 10)

Now, since they took the same time, then we know that;

21/x = 15/(x - 10)

15x = 21x - 210

6x = 210

x = 210/6

x = 35

Thus, Erins speed = 35 mph

range = 11

Step-by-step explanation:

the range is the difference between the largest and smallest value in the data set.

largest value = 18 , smallest value = 7 , then

range = 18 - 7 = 11

11 is the range of the data 8,9,7,11,18,13

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The given data is 8,9,7,11,18,13​

closed circle means 10 is a possible answer

m is greater or equal to 10

it's the 1st and 4th options

Step-by-step explanation:

Answer:

m ≥ 10 and it's a closed circle that is a possible answer.

Step-by-step explanation:

Rules:

Open circle: < (going left) or > (going right)

Closed circle: ≤ (going left) or ≥ (going right)

Here, we have a closed circle at 10, going right (≥).

Therefore, the correct answers are: m ≥ 10 and it's a closed circle that is a possible answer.

This means that m is equal to 10, or any value that is greater than 10.
