What number is 20% of 60

KonstantinChe [14]

We know that 10% of 60 is 6.

60*.1= 6

So,

6+6= 12 or 20% of 60.

12 is the number.

I hope this helps!

Suppose the manager of a restaurant in a commercial building has determined that the proportion of customers who drink tea is 24

BartSMP [9]

Answer:

0.427

Step-by-step explanation:

Standard error for the sampling distribution refers to the standard deviation of the samples taken from a population. The standard error equals the standard deviation divided by the square root of the sample size

The probability of customers who drink tea (p) = 24% = 0.24, the sample size of customers (n) = 300.

Standard error = $\frac{\sigma}{\sqrt{n} }$ where σ is the standard deviation.

$\sigma=\sqrt{np(1-p)}$

Standard error = $\frac{\sigma}{\sqrt{n} }= \frac{\sqrt{np(1-p)} }{\sqrt{n} } =\sqrt{\frac{np(1-p)}{n} } =\sqrt{p(1-p)}=\sqrt{0.24(1-0.24)} =0.427$

If a+b+c=8 and x+y=7 what is -8y-2c-2b-8x-2a

sergey [27]

Answer:

-40

Step-by-step explanation:

Try rearranging and factoring -8y-2c-2b-8x-2a:

This is equal to -8(x + y) -2(a + b + c).

Since x + y = 7, we have:

-8(7) -2(a + b + c)

and since a + b + c = 8, we end up with:

-56 - 2(8), or

-56 - 16 = -40
