At a game show, there are three doors marked 1, 2, and 3. A contestant is allowed to select one of three keys labeled A, B, and C and then use it to open one of the doors. The sample space showing the ways in which a contestant can select a key and a door is represented in the table.

Door
1 2 3
Key A A-1
A-3
B B-1 B-2 B-3
C C-1 C-2
C-3


What is the missing term in the table? If there were two doors instead of three doors, what would the sample size be?

A.
The missing term is A-2. The sample size would be 6.
B.
The missing term is C-2. The sample size would be 8.
C.
The missing term is C-2. The sample size would be 9.
D.
The missing term is B-2. The sample size would be 12.

Answers

Answer 1

Answer:

It is A

Step-by-step explanation:

Answer 2

The answer is A. The missing term is A-2. The sample size would be 6.

a. To answer the question, we need to know what sample space is.

What is a sample space?

A sample space is the total number of possible outcomes of an event.

Now, since there are Doors 1, 2 and 3 and Keys A, B and C. The sample space is

Key A: A-1, A-2, A-3

Key B: B-1, B-2, B-3

Key C: C-1, C-2, C-3

So, the missing item is A-2.

b.

The sample size would be 6.

To answer the question, we need to know what sample size is.

What is sample size?

The sample size is the size of the sample space.

If there were two doors instead of 3, the sample size would be since we have 2 doors and 3 keys. The sample size is 2 × 3 = 6.

So, the sample size would be 6.

So, the answer is A. The missing term is A-2. The sample size would be 6.

y=-7/8

Step-by-step explanation:

-4y-10=4y-3

The length of a rectangle is 3 centimeters less than five times its width. Its area is 14 square centimeters. Find the dimensions of the rectangle.
Find the Width and the Length
W=
L=​

Answers

Answer:

The length of rectangle is 7 cm and width is 2 cm.

Step-by-step explanation:

Given that:

Area of rectangle = 14 square centimeters

The length of a rectangle is 3 centimeters less than five times its width.

Let,

L be the length and W be the width of the rectangle.

L = 5W - 3

Area of rectangle = Length * Width

14 = (5W-3)*W

[tex]14=5W^2-3W\\5W^2-3W-14=0[/tex]

Factorizing the equation;

[tex]5W^2-10W+7W-14=0\\5W(W-2)+7(W-2)=0\\(5W+7)(W-2)=0[/tex]

Either,

5W+7 = 0

5W = -7

W = -7/5

Or,

W-2 = 0

W=2

As width of rectangle cannot be negative, therefore,

Width = 2 centimeters

Length = 5(2) -3 = 10-3 = 7

Hence,

The length of rectangle is 7 cm and width is 2 cm.

Answer:

See below, sorry for taking so long

Step-by-step explanation:

1.

A. Slope is rise over run or y2 - y1 divided by x2 - x1

We have (-5, 1) and (-3, 7)

7 - 1 / -3 - (-5)

6 / -3 + 5

6 / 2 = 3

Slope = 3

B. So point slope form is y - y1 = m(x - x1)

We know the slope so:

y - 1 = 3(x - (-5))

C. Using the point slope we can move things around to get slope-intercept:

y - 1 = 3(x + 5)

y - 1 = 3x + 15

y - 1 + 1 = 3x + 15 + 1

y = 3x + 16

D. Standard form is Ax + By = C:

y = 3x + 16

y - y = 3x + 16 - y

0 = 3x + 16 - y

0 - 16 = 3x + 16 - y - 16

-16 = 3x - y

3x - y = -16

In a study investigating the effect of car speed on accident severity, the vehicle speed at impact was recorded for 5,000 fatal accidents. For these accidents, the mean speed was 46 mph and the standard deviation was 13 mph. A histogram revealed that the vehicle speed distribution was mound shaped and approximately symmetric. (Use the Empirical Rule.) (a) Approximately what percentage of vehicle speeds were between 33 and 59 mph

Answers

Answer:

68%

Step-by-step explanation:

Given that:

Mean speed (m) = 46

Standard deviation (s) = 13

Approximately what percentage of vehicle speeds were between 33 and 59 mph

Obtain the Zscore for P(Z < x) for both values and subtract :

For x = 33

Zscore :

Z = (x - m) / s

Z = (33 - 46) / 13 = - 1

p(Z < - 1) = 0.15866 ( Z probability calculator)

For x = 59

Zscore :

Z = (x - m) / s

Z = (59 - 46) / 13 = 1

p(Z < 1) = 0.84134 ( Z probability calculator)

Hence, 0.84134 - 0.15866 = 0.68268 = 0.68

0.68 * 100% = 68%

What is the approximate surface area of the sphere? Round to the nearest hundredth and use 3.14 for 7. Recall the
formula SA-4x7

Answers

Answer:

Option (3)

Step-by-step explanation:

Formula to get the surface area of a sphere is,

Surface area of a sphere = 4πr²

Here 'r' = Radius of a sphere

Since, r = 9 units and π = 3.14

Surface area of the sphere = 4(3.14)(9)²

                                             = 1017.36 square ²units

Therefore, Option (3) will be the correct option.
