Answer:
60 miles; $30
Step-by-step explanation:
Given:
y = 0.25x + 15 ...........Eq1
y = 0.50x.............Eq2
Where, x = miles and y = Total cost of ranting
Find:
Total cost of ranting.
Computation:
From Eq1 and Eq2
0.25x + 15 = 0.50x
0.25x = 15
x = 15 / 0.25
x = 60 miles
From Eq 2
y = 0.50(60)
y = $30
Answer:
6) not equivalent
7) equivalent
Step-by-step explanation:
6)
2 (3x - 5)
6x - 10
6x - 8 ≠ 6x - 10
7)
2 - 2 + 5x
5x
5x = 5x
Answer:3.42
Step-by-step explanation:to get the answer to a area equation you need to multiply the length by the width.
Given:
p = 90% = 0.9, the probability that the seed grows into a healthy plant.
Therefore
q = 1 - p = 0.1, the probability that the seed will not grow into a healthy plant.
n = 7, the number of seeds planted.
Let r = 4, expected number of seeds that will grow.
Use the Binomial distribution to determine
P(4 of 7 seeds will grow) = ₇C₄ p⁴q⁽⁷⁻⁴)
= 35*(0.9⁴)*(0.1³)
= 0.023
P(4 of 7 seeds will not grow) = 1 - P(4 of 7 seeds will grow)
= 1 - 0.023
= 0.977 or 97.7%
Answer: 97.7%
Answer:
l = 6 inches
Step-by-step explanation:
We have,
The volume of a rectangular prism with a square base is .
Height of the prism is 5 in
It is required to find the length of the edge of the square base. Let it is l.
The formula of the volume of the rectangular prism is given by :
A is area of base of prism
It has a square base, l =b
So, the length of the edge of the square base is 6 inches.
