Answer:
The answer is Factorisation.
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.
Answer:
1 x 31 OR 15.5 x 2
Step-by-step explanation:
As 31 is a prime number, the only whole numbers that do it are 1 × 31. There is another method using decimals. Ex: 15.5 x 2=31
The probability is about 85.29%.
To do this, you need to first find the z-score on each end of the interval. Then, you can subtract the percents to find the percent in the middle.
Lower:
(1000 - 1252) / 129 = -1.18 which gives a probability of 11.9%
Upper:
(1500 - 1252) / 129 = 1.92 which gives a probability of 97.19%
97.19 - 11.9 = 85.29
7/10=70/100=70%, so the answer is seventy-percent.
