(PLEASE HELP!) The probability of drawing a pink marble from a bag containing these marbles is 3/10.
If you replace the marble each time, predict how many times a pink marble will be chosen out of 100 draws.

Answers

Answer 1

Answer:

30

Step-by-step explanation:

The mean is equal to the number of trials times the probability.

x = (3/10) (100)

x = 30

We expect to draw a pink marble 30 times.

Question 26 (1 point)
Find the distance between points P(7.1) and Q(5,7) to the nearest tenth.
PQ =

Answers

Answer:

The answer is 6.3 units

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

P(7,,1) and Q(5,7)

We have

[tex] |PQ| = \sqrt{ ({7 - 5})^{2} + ({1 - 7})^{2} } \\ = \sqrt{ {2}^{2} + ({ - 6})^{2} } \\ = \sqrt{4 + 36 } \: \: \: \: \: \: \: \: \: \\ = \sqrt{40} \: \: \\ = 2 \sqrt{10} \\ = 6.32455532...[/tex]

X=42. Your multiply the 2 with the x then the 2 with the -8. Then your problem would be 2x-16=68. After that you add 16 to both sides, so the -16 cancels out. So now your problem would be 2x=84. Then divide 2 into the 84 then your answer would by x=42

Answers

Answer:

1

Step-by-step explanation:

y-4=(x-2)

This equation is in point slope form

y-y1 = m(x-x1)

where m is the slope

The slope is 1

y - 4 = x - 2

y = x + 2

Slope-intercept form is y = mx + b, where m is the slope and b is a constant.

Here, m = 1 and b = 2. Therefore, the slope is 1.

The number of hours worked by each of the employees last week at two stores are listed below.

Hours Worked in a Week at Two Stores
Store 1 16, 28, 36, 40, 78
Store 2 22, 27, 33, 36, 40

Which statements are true and supported by the data in the table? Check all that apply.
The data for store 1 shows greater variability.
The median number of hours worked for the two stores is the same.
The mean of the data for store 1 is greater than the mean of the data for store 2.
The interquartile range of both data sets is the same.
The range of the data for store 1 is less than the range of the data for store 2.

Answers

Answer:

The correct options are;

1) The data for store 1 show greater variability

2) The mean of the data for store 1 is greater than the mean of the data for store 2

Step-by-step explanation:

The given information are;

Hours worked in a week

Store 1

16, 28, 36, 40, 78

Store 2

22, 27, 33, 36, 40

Using an online application, we have;

For store 1

The range is 78 - 16 = 62

Mean  = 39.6

Standard deviation ≈ 20.88 (Higher variability)

Median = 36

Lower quartile = 22

Upper quartile = 59

Interquartile range = 59 - 22 = 37

For store 2

The range is 40 - 22 = 18

Mean  = 31.6

Standard deviation ≈ 6.41  (Lower variability)

Median = 33

Lower quartile = 24.5

Upper quartile = 38

Interquartile range = 38 - 24.5 = 13.5

Answer:

The correct answers are:

1) The data for store 1 shows greater variability.

3) The mean of the data for store 1 is greater than the mean of the data for store 2.

Which situation represents causation rather than correlation?

D. as a total number of family member increases the amount of money that the family spends on food increases

Answers

Answer: D. as a total number of family member increases the amount of money that the family spends on food increases

Step-by-step explanation:

Correlation is used to describe the 5kinf of relation between two variables whereas causation is relationship between the cause and effect.'

i.e. independent variable acts like a cause to effect the dependent variable.

This can be seen only in Option D. as it is very obvious that increase in family member will increase the cost of food.

Hence, there is direct effect of number of people on food's cost.

Rest of options represents correlation but not causation .

Hence, the correction option is D.

Given A(2,14), B(2,3), C(4,2), and D(14,2) what is the distance of CD?

Answers

Answer: CD = 10

Step-by-step explanation:

Subtract the smaller one from the larger one.

D(14, 2) - C(4, 2)

First, you subtract the x-values:

14 - 4 = 10

Then, you subtract your y-values:

2 - 2 = 0

Since the y-value is 0 (since it is a straight line), your distance of CD is 10.
