Answer:
5
Step-by-step explanation:
Because the square root of 25 is 5 so then do 25 divided by 5 to get 5 as your awnser.
Given:
Sample size, n = 40
Sample mean, xb = $6.88
Population std. deviation, σ = $1.92 (known)
Confidence interval = 90%
Assume normal distribution for the population.
The confidence interval is
(xb + 1.645*(σ/√n), xb - 1.645*(σ/√n)
= (6.88 + (1.645*1.92)/√40, 6.88 - (1.645*1.92)/√40)
= (7.38, 6.38)
Answer: The 90% confidence interval is (7.38, 6.38)

Answer:
x =4.5
Step-by-step explanation:
this is an isosceles triangle
the legs are equal
4x + 6 = 6x - 3
subtract 6 from both sides
4x +6 - 6 =6x - 3 - 6
4x = 6x - 9
subtract 6x from both sides
4x -6x = 6x - 6x -9
-2x = -9
divide both sides by -2
-2x /-2= -9/-2
x =4.5
