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.
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.
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.

There are 1275 ants in 5 anthills how many are in 1 anthill?
Answer:
There are 255 ants in 1 anthill.
Step-by-step explanation:
Do the cross multiplication method. First set the equation as 1275/5 = x/1. Then cross multiply to get 5x = 1275. Divide both sides by 5 to get 255.
Which situation represents causation rather than correlation?
A. as the number of injured players on the sports team increases the number of fans attending the teams game increases
B. as more swimsuits are sold by department stores more sailboats are rented at the marina
C. as more people carry their umbrellas to work more people dress and heavier clothing
D. as a total number of family member increases the amount of money that the family spends on food increases
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.
Examine the system of equations at right. y=-2x + 6 y = -9
a. Solve the system below twice graphically and algebraically. Verify that your solutions from the different methods are the same.
b. What is the relationship between the two lines? How can you tell?
c. Solve the system at right using your method of choice. 2x + 3y = 18 4x - 3y = 6
Answer: -6
Step-by-step explanation: y-intercept: Put x = 0 in the equation y = 2x - 6 and solve for x. The y-intercept is -6

What is the slope of the line whose equation is y-4=(x-2)?
6
S
3 2
1
-5-5-32
+
23
5 x
2719 2
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.

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

Question 26 (1 point)
Find the distance between points P(7.1) and Q(5,7) to the nearest tenth.
PQ =
Answer:
The answer is 6.3 unitsStep-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]
