92% of what number is 253?

1 answer:

3 0

Let, the number = x
Then, x * 92% = 253
x = 253 / 0.92 [ 92% = 0.92 ]
x = 275

In short, Your Answer would be 275

Hope this helps!

Answer: 235

Step-by-step explanation:

The formula to calculate the sample size :-

$n=(\hat{p}(1-\hat{p}))(\dfrac{z_{\alpha/2}}{E})^2$

Given : Estimated proportion $\hat{p}=0.89$

Margin of error : $E=0.04$

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2} =1.96$

Now, the required sample size will be :-

$n=(0.89(0.11))(\dfrac{(1.96)}{0.04})^2$

$\Rightarrow\ n= 235.057\approx235$

Hence, the required minimum sample size = 235

Look at the steps used when solving 3(x - 2) = 3 for X.

Setler [38]

Answer:

3×-6=3

3×=3+6

3×=9

×=3

Step-by-step explanation:

multiply 3 by the variables in the bracket.

then you will get 3×-6=3.

take the -6 to the right hand side and it becomes+6

then you get 3×=3+6 therefore =3×=9

then divide both sides by 3.

3×÷3 and 9÷3

×=3

For each value of y , determine whether it is a solution to 3y<24.

Lina20 [59]

Answer:

1) No

2) Yes

3)No

4)Yes

Step-by-step explanation:

1) 3(8) is simplified to 24

But 24 < 24 is not a true statement because they are both equal.

2) 3(5) is simplified to 15

15 < 40 is a true statement because 15 is less than 24

3) 3(11) simplifies to 33

33 < 24 is not a true statement because 33 is more than 24

4) 3(6) simplifies to 18

18 < 24 is a true statement because 18 is less than 24

Hope this helped.
