Step-by-step explanation:
Sample data
204.999 206.149 202.102 207.048 203.496 206.343 203.496 206.676 205.831
N=9
Sum, Σx: 1846.14
Mean, μ: 205.12666666667
Variance, s^2: 2.6217475555555
Std dev = s = 1.619
The sample mean follows a t distribtion with df =8
Mean difference = 205.13-204.8 = 0.50
Std error = std dev/sqrt n = 0.540
Test statistic = Mean diff/se = 0.9259
p value = 0.1907 (one tailed at 95%)
Since p >0.05 we accept null hypothesis.
We cannot conclude that the mean shade of Mezza Perla tile (µ) is greater than 204.8
Let's say that y is the weight of the mother and x is the weight of the baby.
We know that the baby is 7437 pounds less than the mother, which means you need to add 7437 pounds to the baby's weight to get the mother's.
We can show it like this:
x+7437=y.
We know what the baby's weight is (1400 lbs), so just sub it in:
1400+7437=y
y=8837 lbs
The mom weighs 8837 pounds.

Explanation:
Recall that from a previous screenshot you posted, that
If we multiply both sides by 3 and swap both sides, then we end up with
So that's why we need 3 cups of water, if each cup is the cone in the diagram. Keep in mind that the height of the cylinder and the cone must be same. The two radius values must be the same as well. You don't need to have r = h be true.
The best method to measure the thickness of a quarter is (C) Centimeters.
This is because the thickness of a quarter is very small and thus bigger units such as meters and kilometers will not be convenient. Centimeters is the best unit.
