The sum of two numbers is 35. Three times the larger number is the same as 4 times the smaller number. Find the smaller number

1 answer:

3 0

If 35-x is the smaller number and x is the larger number, we can take that 3*x=4*(35-x)=140-4x. Subtracting 3x from both sides, we get 140-7x=0. Adding 7x to both sides, we get 140=7x. Lastly, we can divide both sides by 7 to get x=20

Given that a 90% confidence interval for the mean height of all adult males in Idaho measured in inches was [62.532, 76.478]. Wh

NNADVOKAT [17]

Answer:

The point estimate used to estimate the mean height of all adult males in Idaho is 69.505 inches.

Step-by-step explanation:

Each confidence interval has two bounds, the lower bound and the upper bound. The points estimate used to estimate the mean is the halfway point between those two bounds, that is, the sum of those two bounds divided by two.

In this problem, we have that:

Lower bound: 62.532

Upper bound: 76.478

Point estimate: (62.532 + 76.478)/2 = 69.505

The point estimate used to estimate the mean height of all adult males in Idaho is 69.505 inches.
