3.6 (5 x 4) ÷ 3 + 5.0
use the PEMDAS rule
P - parentheses
E - exponents
M - multiplication
D - division
A - addition
S - subtraction
3.6 (5 x 4) ÷ 3 + 5.0
= 3.6 (20) ÷ 3 + 5.0
= 72 ÷ 3 + 5.0
= 24 + 5.0
=29
so the final answer would be 29!!
3 bags my g have a awesome day
X is equal to 2. put 2 in for X and try to solve it
Answer:
a. mean = 1000
standard deviation = 4358.9
b. expected value of average damage bar Y = 1000
probability bar y exceeds 2000 = 0.011
Step-by-step explanation:
we have p1 = 95%, y1 = 0, p2 = 5%, y2 = 20000
Mean = (0.95 * 0) + (0.05 * 20000)
= 1000
var(y) = E(y²) - E(Y)²
= we solve for E(y)²
= 0²*0.95 + 20000²*0.05
= 0 + 20000000
then the variance of y = 20000000 - 1000²
=20000000-1000000
= $19000000
standard deviation is the square root of variance
= √19000000
= 4358.9
2.
a. Expected value of average is also the mean = 1000
b. we are to find probability that barY exceeds 2000

= 1000/435.889
= 2.29
1-p(z≤2.29)
= 1 - 0.989
= 0.011
so the probability that barY exceeds 2000 is 0.011
Volume of a Rectangular Prism = Length * Width * Height
Step 1:
Double your dimensions
5 cm x 2 = 10 cm
3 cm x 2 = 6 cm
4 cm x 2 = 8 cm
Step 2:
Multiply them together
Volume = 10 x 6 x 8
Volume = 60 * 8
Volume = 480 cm^3
