What is 2 to the second power

Mathematics
2 answers:
valentinak56 [21]2 years ago

Answer:

The answer is <u>4</u>

Step-by-step explanation:

Another term for 2 to the second power is 2 squared.

Any time you square something you multiply that number by itself. So in reality that problem would be 2 times 2.

If it were a bigger number you would multiply the number by itself the about of times you see if anything is to the first power it stays the same so squared is a number times itself, and cubed which is the third power would be:

2 x 2 x 2.

2 x 2 or 2 to the second power or 2 squared equals<u> 4</u>.

Hope this helps.

Answer:

4.

Step-by-step explanation:

2 to the second power = 2^2.

2^2 means 2*2 = 4.

The 2 in  ^2 is called the 'exponent' .

Note 3^3 = 3*3*3

and 5^5 = 5*5*5*5*5.

NEED HELP ASAP!!!
Sergeeva-Olga [200]

Answer:

(b) P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}

Step-by-step explanation:

Let E: Event of getting a 3 in the spinner.

So, the number of favorable outcomes  =  11

Total number of outcomes = Number of times the outcomes is {1,2,3,4,5,6}

= {13 +10 +11+16+11}  = { 61}

So, the total number of outcomes = 61

\textrm{Probability of Event E}  = \frac{\textrm{Number of favorable events}}{\textrm{Total number of outcomes}}

So, here P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}

Paula, the local baker, usually makes 15 loaves of bread and 10 cakes per day, but today she made 25 loaves of bread and 12 cake
frozen [14]

Answer:

Step-by-step explanation:

The percent increase formula is

%increase=\frac{new-original}{original}*100%

For the bread, our percent increase looks like this:

\frac{25-15}{15}*100

which gives us a percent increase of 66.7%

For the cakes, our percent increase looks like this:

\frac{12-10}{10}*100

which gives us a percent increase of 20%

In a survey, the planning value for the population proportion is . How large a sample should be taken to provide a confidence in
tatuchka [14]

Answer:

n=350

Step-by-step explanation:

Notation and definitions

n random sample taken  (variable of interest)

\hat p=0.35 estimated proportion  (value assumed)

p true population proportion

Confidence =0.95 or 95% (value assumed)

Me=0.05 (value assumed)

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The population proportion have the following distribution

p \sim N(p,\sqrt{\frac{\hat p(1-\hat p)}{n}})

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by \alpha=1-0.95=0.05 and \alpha/2 =0.025. And the critical value would be given by:

z_{\alpha/2}=-1.96, z_{1-\alpha/2}=1.96

The margin of error for the proportion interval is given by this formula:  

ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}    (a)  

And on this case we have that ME =\pm 0.05 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}   (b)  

And replacing into equation (b) the values from part a we got:

n=\frac{0.35(1-0.35)}{(\frac{0.05}{1.96})^2}=349.586  

And rounded up we have that n=350
