Answer:
Step-by-step explanation:
3 * 4 = 12 - 6
12 = 6
This statement is false
Answer:
41 139/1000
Step-by-step explanation:
41.139
41 139/1000
The formula to solve for the volume (V) of a rectangular prism is,
V = L x W x H
where L is the length, W is width, and H the height or depth.
Substituting the known dimensions on the equation above,
V = (4 in) x (9 in) x (2.2 in) = 79.2 in^3
Thus, the volume of the cake pan is 79.2 in^3.
The 68-95-99.7 rule tells us 68% of the probability is between -1 standard deviation and +1 standard deviation from the mean. So we expect 75% corresponds to slightly more than 1 standard deviation.
Usually the unit normal tables don't report the area between -σ and σ but instead a cumulative probability, the area between -∞ and σ. 75% corresponds to 37.5% in each half so a cumulative probability of 50%+37.5%=87.5%. We look that up in the normal table and get σ=1.15.
So we expect 75% of normally distributed data to fall within μ-1.15σ and μ+1.15σ
That's 288.6 - 1.15(21.2) to 288.6 + 1.15(21.2)
Answer: 264.22 to 312.98
3x^2 / 4 = 48
Multiply both sides by 4 to get rid of the four on the left.
3x^2 = 192
Divide both sides by 3
x^2 = 64
The square root 64 to get x
Remember there are two answers
x = 8 and x = -8
