Answer:
And we can use the normal table and the complement rule we got:
Step-by-step explanation:
For this case we have the following parameters given:
We select a ample size of n=49. And we want to find this probability:
And for this case is a right tail probability and we can use the z score formula given by:
And replacing we got:
And we can use the normal table and the complement rule we got:
Cmon this is easy it is 24 okay
Answer:
4
Step-by-step explanation:
All the sides of an equilateral triangle are equal, hence the perimeter is expressed as P = 3s
s is one of the side length
Given DE = 5x - 8
P = 3DE
P = 3(5x-8)
36 = 3(5x-8)
36/3 = 5x-8
12 = 5x - 8
5x = 12+9
5x = 20
x = 20/4
x = 4
Hence the value of x is 4
Answer:
Step-by-step explanation:
→ State the gradient formula
( y₂ - y₁ ) ÷ ( x₂ - x₁ )
→ Find x₁ , x₂ , y₁ and y₂
x₁ = 4 , x₂ = 12 , y₁ = 9 and y₂ = 20
→ Substitute in the values
→ Simplify
Answer:
each clinic serves about 300 people
Step-by-step explanation:
Population of 24742 is served by 83 clinics
Then each clinic will serve
24742/83 =298.157
≈ 300
