1. 32+34+36=102
2. 250/1×7/10=1750/10= 175
250-175= 75 more gallons
3. 77.7, 77 7/100= 77.07 so 77.7 is larger
4. 1,026,231
5. 16 cubes, 4 each way because 8÷2=4 and 4^2 is 16
6 1/4 cubes for 4cm because area of 4cm cube is 16 and area of 10 cm is 100, and 100÷16=6.25 or 6 1/4

b)
0.125 = 12.5% probability that all three coins come up heads.
0.875 = 87.5% probability that there will be at least one tail.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Question a:
Considering H for heads, T for tails:
H - H - H
H - H - T
H - T - H
H - T - T
T - H - H
T - H - T
T - T - H
T - T - T
(b) What is the probability that all three coins come up heads?
One outcome(H - H - H) out of 8, so:
0.125 = 12.5% probability that all three coins come up heads.
Notice that the complement of the event "3 heads" is "at least one tail." Use this information to compute the probability that there will be at least one tail.
Sum of these probabilities is 100%, so:
1 - 0.125 = 0.875
0.875 = 87.5% probability that there will be at least one tail.
The probability is simply the chance you have of getting each color.
Therefore:
Black= 4/12 or 1/3
Blue or Red= 8/12 or 2/3
Answer:
3(2*-1)^2
solved is: 12
Step-by-step explanation:
Answer:
a) Yes b) No
Step-by-step explanation:
Given that the p value for a two-sided test of the null hypothesis H0: μ = 10
is 0.06
a)
Hence we accept null hypothesis
This implies that 10 will be within the confidence interval of 95%
b) If confidence level = 90%
So we have to reject null hypothesis.
So we do not have 10 in the confidence interval
The reason is the lower the confidence level, the narrower the confidence interval. In this case, 10 has gone outside the narrower interval hence we get this.
