Given:
Total number of calculators in a box = 10
Defective calculators in the box = 1
To find:
The number of ways in which four calculators be selected and one of the four calculator is defective.
Solution:
We have,
Total calculators = 10
Defective calculators = 1
Then, Non-defective calculator = 10-1 = 9
Out of 4 selected calculators 1 should be defective. So, 3 calculators are selected from 9 non-defective calculators and 1 is selected from the defective calculator.






Therefore, the four calculators can be selected in 84 ways.
The answer is -28 if there is a negative then the answer is a negative

Answer:
1. y = 4x - 4
2. y = x + 2
3. y = -2x - 4
4. y = -x + 2
Step-by-step explanation:
Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.
Answer:
<em><u>C</u></em>
Step-by-step explanation:
if h<28
- its area= 28×28 = 784, but it is greater than 15 sq inches
- Its volume = 28×28×28 = 21952, but it is greater than 285 cubic inches
hence h must be less than 28 (h<28)
And not greater than √15 ( h<√15)
