Step-by-step explanation:
k = 2h+9
h+16=k
h+16=2h+9
-h = -7
h = 7
hannah is 7 and kayla is 23
jacob is wrong because if u do 16*2+7 it’s 39 and 39-16 does not equal 16
1-2. The best estimate for the population mean would be sample mean of 60 gallons. Since we know that the sample mean is the best point of estimate. Since sample size n=16 is less than 25, we use the t distribution. Assume population from normal distribution.
3. Given a=0.1, the t (0.05, df = n – 1 = 15)=1.75
4. xbar ± t*s/vn = 60 ± 1.75*20/4 = ( 51.25, 68.75)
5. Since the interval include 63, it is reasonable.
