Suppose b is any integer. If b mod 12 = 5, then 7b mod 12
Rzqust [24]

The result follows directly from properties of modular arithmetic:

b\equiv5\pmod{12}\implies 7b\equiv35\equiv-1\equiv\boxed{11}\pmod{12}

That is,

b\equiv5\pmod{12}

means we can write b=12n+5 for some integer n. Then

7b=7(12n+5)=12(7n)+35

and taken mod 12, the first term goes away, so

7b\equiv35\pmod{12}

etc

Complete Question

The complete question is shown on the first uploaded image

Answer:

The confidence level interval is  0.016 \le C \le 0.404

Step-by-step explanation:

The sample size is  n =  20

The number planning to increase workforce is  x =  3

 The confidence level is  c  = 98%

The value of proportion for a plus 4 method is

      p = \frac{x+2}{n+4}

substituting values

      p = \frac{3+2}{20+4}

       p =0.21

The z-critical value at confidence level of 98% is

     z_{c}=z_{0.98} =  2.33

This values is obtained from the standard normal table

The confidence level interval can be mathematically represented as

      C =p \ \pm z_{c} * \sqrt{\frac{p(1-p)}{n+4} }

substituting values

      C = 0.21 \pm 2.33 * \sqrt{\frac{0.21(1- 0.21)}{20 +4} }

       C = 0.21 \pm 0.194

=>   0.016 \le C \le 0.404
