Answer:
Standard deviation = 7.76
Step-by-step explanation:
The formula for determining standard deviation when dealing with population proportion is expressed as
Standard deviation = √npq
Where
n represents the number of samples from the population.
p represents the probability of success.
q represents the probability of failure.
From the information given,
n = 500 policyholders
p = 14% = 14/100 = 0.14
q = 1 - 0.14 = 0.86
Standard deviation = √500 × 0.14 × 0.86 = 7.76

because there are four balls therefore 1 out of 4 is going to be the answer
Answer:
b) Scalene Acute
Step-by-step explanation:
b) Scalene Acute
A scalene triangle is a triangle with none of its sides equal to each other. Here, The sides MN,NO,OM with their respective values of 4.94,4.65.3.65 are not equal. Hence, Scalene.
An acute triangle is a triangle in which the largest angle of the triangle is more than 90 degree. Here, Neither 63, 45 nor 72 are greater than 90 degrees.
Hence, Acute
Answer 8400 divided by 7 is 1200
78+92=170
170/2=85
his current average is 85% so id go with C knowing that if his next quiz he got at least a 70, his average would be 80%
