Find the value of x.
hjlf

Answer:

x = 14

Step-by-step explanation:

Since they are similar triangles, their sides are proportional

12 : 15  :: 8 : x - 4

Product of extremes = Product of means

12 × ( x- 4 ) = 15 × 8

12x -48 = 120

12x = 120 + 48

12x = 168

x = 168/12

x = 14

Each year, all final year students take a mathematics exam. It is hypothesized that the population mean score for this test is 8
drek231 [11]

Answer:

95% Confidence interval:  (96.06,103.94)

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 85

Sample mean, \bar{x} = 100

Sample size, n = 30

Alpha, α = 0.05

Population standard deviation, σ = 11

95% Confidence interval:

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

100 \pm 1.96(\frac{11}{\sqrt{30}} ) = 100 \pm 3.94= (96.06,103.94)

(96.06,103.94) is the 95% confidence interval for  the population mean test score.
