Under 45 mins is roughly 16%. This is because 68% of the curve exists within 1 SD of the mean. So 16% must be outside and smaller and 16% outside and larger (on average).
It is impossible to determine how likely you are to find someone with exactly the second amount. However, if you are looking for that or less, you would get 84%
Answer:
x = 5
Step-by-step explanation:
Given
= ( cross- multiply )
6x = 30 ( divide both sides by 6 )
x = 5
Answer:
The area of a trapezoid = 1/2 (altitude)(base 1 + base 2)
Step-by-step explanation:
Answer:
1. 5w+2(w+5) = 5w+2w+10
7w+10-6w+2(9w+3) = 1w+18w+10+6
19w+16+38-4w = 15w+54
15w+54
2. 3(5w+18)
5w(3)= 15w
18(3)=54
15w+54
The length of the baby's head is 5.5 inches if the ratio of a baby's head length to the length of the rest of the body is 1:3.
<h3>What is the ratio?</h3>
It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that:
At birth, the ratio of a baby's head length to the length of the rest of the body is 1:3.
A baby's total body length is 22 inches,
Let x be the head length
Let 3x be the
x + 3x = 22
4x = 22
x = 22/4 = 11/2 = 5.5 inches
Thus, the length of the baby's head is 5.5 inches if the ratio of a baby's head length to the length of the rest of the body is 1:3.
