Subtract normally as if 32.6 is 316 and 1.9 is 19. Then you move the decimal point two places to the left of the answer

the answer is 29.7

The next term in 3, 12, 48, 192,768,...

geniusboy [140]

3 * 4 = 12

12 * 4 = 48

48 * 4 = 192

192 * 4 = 768

The next number in the sequence is the previous number multiplied by 4:

The next number would be 768 x 4 = 3072

A software developer wants to know how many new computer games people buy each year. Assume a previous study found the standard

Marrrta [24]

Answer:

The minimum sample size required to ensure that the estimate has an error of at most 0.14 at the 95% level of confidence is n=567.

Step-by-step explanation:

We have to calculate the minimum sample size n needed to have a margin of error below 0.14.

The critical value of z for a 95% confidence interval is z=1.96.

To do that, we use the margin of error formula in function of n:

$MOE=\dfrac{z\cdot \sigma}{\sqrt{n}}\\\\\\n=\left(\dfrac{z\cdot \sigma}{MOE}\right)^2=\left(\dfrac{1.96\cdot 1.7}{0.14}\right)^2=(23.8)^2=566.42\approx 567$

The minimum sample size to have this margin of error is n = 567.

Answer:

Step-by-step explanation:

Let's simplify each term.

$(\frac{1}{4})^{2} = 0.0625$

$4^{3} =64$

$(4-1) = 3$

Now we multiply:

$0.0625*64*3 = 12$

Hope this helps!
