Liula [17]

Answer:

Adult required in the case of “a” 28 and in the case of “b” the adult requirement is 19.

Step-by-step explanation:

(a) The percentage of adult that support the change is 20 percent.

Now calculate the number of adult required.

Given p = 0.20

Use the below condition:

np(1 – p) \geq 10 \\n \times 0.20 (1 – 0.20) = 10 \\n = 63 round off

Since 35 adults are already there so required adults are 63 -35 = 28

(b) The percentage of adult that support the change is 25 percent.

Now calculate the number of adult required.

Given p = 0.25

Use the below condition:

np(1 – p) \geq 10 \\n \times 0.25 (1 – 0.25) = 10 \\n = 54 (round off)

Since 35 adults are already there so required adults are 54 -35 = 19 .

-6x-4(-7x-13)=-58 <br> What the answer
taurus [48]

-6x-4(-7x-13)=-58

Multiply the bracket by -4

-6x-4(-7)-4(-13)= -58

-6x+28x+52= -58

22x+52= -58

Move +52 to the other side. Sign changes from +52 to -52.

22x+52-52= -58-52

22x= -110

Divide by 22.

22/22x= -110/22

x= -5

Answer: x= -5
