distance = rate * time
2.56 meters = 2meter/min * t
divide by 2 on each side
2.56/2 =t
1.28 minutes =t
Answer:
13
Step-by-step explanation:
If ABC is equilaterteral then all the angles must be equal and 60°
8x - 44 = 60 add 44 to both sides
8x = 104 divide both sides by 8
x = 13
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.
B is the answer bc you need to subtract before divide, so you need the parenthesis around 36-10
