Answer:
First one equals -15
Second one equals -3
Step-by-step explanation:
(-4)*2 - 7
= (-8) - 7
= (-15)
(-4) + 1
= (-3)
Hopefully this helps.
I think the answer is c due to the word bag being plural but I’m not sure.
Answer:
The transformation is left 1 hope it is right
Step-by-step explanation:
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.
The missing segment is 25
