Answer:
-7 =x
Step-by-step explanation:
−30=5(x+1)
Divide each side by 5
−30/5=5/5 (x+1)
-6 = x+1
Subtract 1 from each side
-6-1 = x+1-1
-7 =x
Step-by-step explanation:
Find the measure of an exterior angle of a regular decagon.
40 degrees.
They are 38 miles apart because 16*2 3/8 = 16*2 + 16*3/8 = 32 + (16/8 = 2*3 =6) = 32 + 6 = 38
48:12
because 60-12 is 48 and 48 plants sprouted and 12 did not
Answer:
Mean = 28.38
Standard Deviation = 4.02
Step-by-step explanation:
Probability that a restaurant failed in the first year = p = 43% = 0.43
The probability of occurrence is constant. The events(failing of restaurants) are independent. Number of trials if fixed and there are only two possible outcomes i.e. either restaurant failed or not failed.
This scenario satisfies all the conditions of a Binomial experiment setting. So, we will use Binomial Experiment to answer the questions.
The formula to calculate the Mean of Binomial Distribution is:
Mean = u = np
Here, n is the number of trials, which is 66 in this case. So,
Mean = u = 66 x 0.43 = 28.38
Standard Deviation of a Binomial Distribution is calculated as:
