The test predicted that Erin will not have a heart attack. The probability after the test was taken that she will have a heart attack is <span>0.4653. the rest of teh choices do not answer the question above.</span>
Answer:
4y^4 + 6y = 256y + 6 = <u>262y</u>
Step-by-step explanation:
Remove the variables for a second and think of the problem as a normal expression; 4^4 + 6
Simplify the first term; 4^4 = 256
Now, add 6; 256 + 6 = 262
Add back in the variable; 262y
15.40 + 8.50l (l is variable for labor)
8.50 x 2.5 = 21.25
15.40 + 21.25 = 36.65.
That is the answer for A.
504.20 - 15.40 = 488.80
488.80 / 8.50 = <span>57.50
About 57.50 hours for B.</span>
Answer:
37 minutes
Step-by-step explanation:
Answer:
x = 2.5 inches. Or
x = 5/2
Step-by-step explanation:
Length: 7 + 2x
Width: 5 + 2x
Note that you have to add x at each end of the picture and onto each part of the width.
The entire area is 120 square inches.
Formula
L*W = Area
(2x + 7)(2x + 5) = 120
Solution
4x^2 + 10x + 14x + 35 = 120 Subtract 120 from both sides. Add xs
4x^2 + 24x + 35 - 120 = 0
4x^2 + 24x - 85 = 0 Factor
(2x + 17)(2x - 5)
2x + 17 has no meaning. It will give - 8.5 which is not possible.
2x - 5 =0
2x = 5 Divide by 2
x = 5/2
x = 2.5
Note: I don't know which one the computer is looking for.
