Answer:
The expected value of each warranty sold is $23.8.
Step-by-step explanation:
0.8% probability of the product failling.
If the product fails, the company will lose 400 - 27 = $373. So a net value of -373.
100 - 0.8 = 99.2% probability of the product not failling.
If the product does not fail, the company gains $27.
What is the company's expected value of each warranty sold?
We multiply each outcome by its probability.
0.008*(-373) + 0.992*27 = 23.8
The expected value of each warranty sold is $23.8.
Answer:
4| 7
5| 2 7 8 8
6| 1 6 6 8 8
7| 0 2 2 3 3 5 6 7
8| 4 4 4 5 6 6 7 9
9| 0 1 1 2 3 7
And with the notation 4|7 represent 47
Step-by-step explanation:
For this case we have the following dataset given:
58 52 68 86 72 66 97 89 84 91 91 92 66 68 87 86 73 61 70 75 72 73 85 84 90 57 77 76 84 93 58 47
And if we order the dataset in increasing way we got:
47 52 57 58 58 61 66 66 68 68 70 72 72 73 73 75 76 77 84 84 84 85 86 86 87 89 90 91 91 92 93 97
And if we create the stem plot we got:
4| 7
5| 2 7 8 8
6| 1 6 6 8 8
7| 0 2 2 3 3 5 6 7
8| 4 4 4 5 6 6 7 9
9| 0 1 1 2 3 7
And with the notation 4|7 represent 47
Answer:
<em>48 drops of red food coloring</em>
Step-by-step explanation:
32/8 = 4
SO she uses 4x as much yellow food coloring meaning you need to use 4x as much red food coloring.
4 x 12 = 48 so she needs to add 48 drops of red food coloring
To find the slope, you should rearrange the equation into slope-intercept form, ie. y = mx + c, where m is the gradient.
y - 9 = 15(x - 5)
y = 15(x - 5) + 9 (Add 9 to each side)
y = 15x - 15*5 + 9 (Expand 15(x - 5))
y = 15x - 75 + 9
y = 15x - 66
Therefor, the slope of the equation is 15.
1. A. Add 6 to both sides to solve.
2. D. If you simplify the a terms you will get 6 = 7 which is never true.
3. A. Subtract 1.2m from both sides and then divide to solve.
4. B. If you simplify you get 7 = 7 which is always true.
5. D. Distribute the 2 and then add the 24 to both sides. Then divide to solve.
6. A. Simplify the right side and then divide all by two. Then add 16 to both sides and divide by 4.
7. 3y - 2
