Answer:

x = 6

Step-by-step explanation:

7(x - 4) = 14

Expansion

7 times x = 7x

7 times -4 = -28

7x - 28 = 14

Collect like terms, add 28 to both sides of the equation

7x - 28 + 28 = 14 + 28

7x = 42

Divide both sides by the coefficient of x which is 7

7x/7 = 42/7

x = 6

To check that x = 6 is the solution to the equation, we substitute the value of x = 6 into the equation

7(x - 4) = 14

7(6 - 4) = 14

7(2) = 14

Answer:

0.1019

Step-by-step explanation:

Probability, p=12%=0.12

Sample size, n=130 students

Those writing with left=14 students

Using the formula for binomial distribution

P(X≤x)= $\left[\begin{array}{}n\\x\end{array}\right]p^{x}(1-p)^{n-x}$

Substituting 0.12 for p, 130 for n, 14 for x we obtain

P(X≤x)= $\left[\begin{array}{}130\\14\end{array}\right]0.12^{14}(1-0.12)^{130-14}$

P(X≤x)= $130C14*0.12^{14}(0.88)^{116}$

P(X≤x)=0.1019
