Slope = (269.50 - 183.75)/(22 - 15)
= 85.75 / 7
= 12.25
Equation
E = $12.25 h
If h = 15, E = $12.25 * 15 = <span>$183.75
</span>
If h = 22, E = $12.25 * 22 = <span>$269.50
</span>
If h = 26, E = $12.25 * 26 = $318.50
Answer
Equation
E = $12.25 h
Answer:
The cone's height is 9
Step-by-step explanation:
Recall that the volume of a cone is: , where 'h' is the cone's height, and "r" the radius of its base.
In our case, we know that the volume of the cone equals; .
We also know the diameter of the base (12), so the radius of the base must be half of this: 6
Now we replace all known values in the formula for the volume, and solve for the unknown "h':
Answer:
a. 0.55
b. 0.68
c. 0.18
Step-by-step explanation:
a. The probability that E2 does not occur is one minus the probability that E2 occurs:
b. The probability that either E1 or E2 occurs is given by the sum of their individual probabilities minus their joint probability:
c. The probability that neither E1 nor E2 occurs is one minus the probability of E1 occurring minus the probability of E2 occurring:
369
60(0.15)=9
1200(0.3)=360
The expression which shows the amount of money, in dollars Maddie spent on mailing letters in March is 3.7 +0.74 y.
Given Maddie mailed y letters in January. She mailed 3 times as many letters in February. In March she mailed 10 letters more than half of what she mailed in January and February.
Expression is combination of numbers, symbols, fraction, coefficients which are not found in equal to form.
Letters mailed in January=y
Letters mailed in February=3y
Letters mailed in March=10+(y+3y)/2
=10+2y
Amount of mailing of 1 letter=$0.37.
Amount of mailing of letters in March=0.37(10+2y)
=3.7+0.37*2y
=3.7+0.74y
Hence the expression which shows the amount of letters mailed in March is 3.7+0.74 y.
