Answer:
(a) = 0.22 hours per dollar, (b) = 8.33 minutes per mile
Step-by-step explanation:
<u>(a): 4/18</u>
0.22 hours per dollar
<u>(b): 25/3</u>
8.33 minutes per mile
Answer: (a) = 0.22 hours per dollar, (b) = 8.33 minutes per mile
2 1/2 pounds of apple makes serve 6
(2 1/2 x 24)/6 = 10 pounds of apple will make serve 24.
Therefore, she will use 10 pounds of apples.
Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)
To get the probability of less than 109.1 cm, the solution is computed by:
z (109.1) = (X-mean)/standard dev
= 109.1 – 108/ 0.6
= 1.1/0.6
=1.83333, look this up in the z table.
P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%
The triangle is acute. Since all triangles have 180 degrees, you can find the third angle by subtracting the sum of the other angles from 180.
180 - (25 + 87) = third angle
180 - 112 = third angle
68 = third angle
Since all three angles are less than 90 degrees, it is an acute triangle.
