Answer: -10
Step-by-step explanation:
9-(-1)/2-3 = -10
Answer:
-7
Step-by-step explanation:
8=r+15
-15 -15
-7=r
check
8=r+15
substitute
8=-7+15
8=8 check
The sample size needs to be 96.
First we find the z-score for this confidence interval:
Convert 95% to a decimal: 95/100 = 0.95
Subtract from 1: 1 - 0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1 = 0.025 = 0.975
Using a z-table (http://www.z-table.com) we look up this value in the chart; the z-score that goes with this value is 1.96.
Now we use the formula
-a+m= n or m-a=n. Pretty sure it’s B
Answer:
The experimental probability P(E) is 0.1818 = 18.18%
Step-by-step explanation:
The experimental probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
11 trials(11 outcomes)
2 kings(2 desired)
So
P(E) = 2/11 = 0.1818
The experimental probability P(E) is 0.1818 = 18.18%
