Add the two fractions together but first rewrite the fractions with a common denominator.
4/15 = 8/30
3/10 = 9/30
8/30 + 9/30 = 17/30
Answer: 17/30

Answer:
The alternate hypothesis is that newborn infants has a mean weight of 7.56 pounds.
Step-by-step explanation:
Let's find an alternate hypothesis by using the formula:
mean=(sum of all data)/(number of data points) so:
sum of all data=9.0+7.3+6.0+8.8+6.8+8.4+6.6=52.9 and:
number of data points=7 so:
mean=52.9/7=7.56 pounds
The alternate hypothesis is that newborn infants has a mean weight of 7.56 pounds.
Answer:
The inverse is 1/64 x^2 = y x ≥ 0
Step-by-step explanation:
f(x) = 8 sqrt(x)
y = 8 sqrt(x)
Exchange x and y
x = 8 sqrt (y)
Solve for y
Divide each side by 8
1/8 x = sqrt(y)
Square each side
(1/8 x)^2 = (sqrt(y))^2
1/64 x^2 = y
The inverse is 1/64 x^2 = y x ≥ 0
since x ≥0 in the original function
