Answer:
Step-by-step explanation:
Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.
Given ratio= elementary schools: middle schools:: 28:16
The ratio can be written as
Now to write into simplest form, we need to divide both numerator and denominator by 4.
∴ elementary schools: middle schools=
Hence, we get simplest ratio of elementary schools to middle schools=
130 + 2x = 180
2x = 180 - 130
2x = 50
x = 50/2
x = 25
2x + 4y + 54 = 180
2(25) + 4y + 54 = 180
50 + 4y + 54 = 180
4y + 104 = 180
4y = 180 - 104
4y = 76
y = 76/4
y = 19
answer: x = 25 and y = 19
Answer:
Pr(all will survive in one year) = 0.35 to 2 decimal places
Pr(at least 8 will survive) = 0.39 to 2 decimal places.
Step-by-step explanation:
Probability of a tree surviving one year is 0.9. While not surviving probability is 1 - 0.9 = 0.1
This is obtained from the 90℅ surviving rate for one year planted by the landscaping firm.
Probability that if 10 trees are planted, all will survive for one year is:
0.9x0.9x0.9x0.9x0.9x0.9x0.9x0.9x0.9x0.9 = 0.9^10 = 0.349
Probability that at least 8 will survive in one year can be expressed as
8 survived x 2 not survived +(or) 9 survived x 1 not survived +(or) 10 survived
= [(0.9^8)x(0.1^2) + (0.9^9)x(0.1^1) + (0.9^10)] = 0.391
Answer:
If the sum is 6, a small cone will be ordered
If the sum is 8 or 9, a medium cone will be ordered.
If the sum is 11, a large cone will be ordered.
Step-by-step explanation:
If the sum is 6, a small cone will be ordered
If the sum is 8 or 9, a medium cone will be ordered.
If the sum is 11, a large cone will be ordered.
The description above accurately explains how a fair decision can be made in this situation. Because the least sum of value = 6
While the highest sum of value of number = 11.
