Answer:
x = 5
Step-by-step explanation:
1. 8 (x + 2) = 56 Distribute the 8
2. 8x + 16 = 56 Subtract 16 from both sides
3. 8x = 40 Divide both sides by 8
4. x = 5
Answer:
0.4459
Step-by-step explanation:
Let the random age variable, X = 4.5; mean,∪ = 4.8; standard deviation, α = 2.2
By comparing P ( 0≤ Z ≤ 4,8)
P(Z ≤ X - ∪/α) = P(Z ≤ 4.5 - 4.8/2.2) = P(Z ≤ - 0.136)
Using the table: P(0≤ Z ≤ 1) = 0.0541
P(Z > 1) = (0.5 - 0.0541) = 0.4459
∴ P(Z > 4.5) = 0.4459
Answer:
4800
Step-by-step explanation:
Given the function
y = 75 × 
x is the number of 15 year periods
45 years has 3 15 year periods , thus x = 3
Substitute x = 3 into the function and solve for y
y = 75 × 4³ = 75 × 64 = 4800
There will be 4800 foxes after 45 years
Answer:
D. 245.
Step-by-step explanation:
If you take 1,085 cars and divide it by 31, and then take that answer and multiply it by 7 you get 245.
Answer:
x=9
Step-by-step explanation:
17x - 12 = 114 + 3x
First Subtract 3x from both sides
14x - 12 = 114
Add 12 to both sides
14x=126
Divide by GCF (14)
x=9
