guapka [62]

Answer:

√37

Step-by-step explanation:

An irrational number is a number that never terminates nor repeats.

Let's go through each of the answer choices.

1) √100 is just 10. This is not irrational.

2) √81 is just 9. This is again not irrational.

3) √64 is 8. Not irrational.

4) √49 is 7. Again, not irrational.

5) √37 is 6.08276253... This number will never end and it doesn't repeat. Therefore, √37 is irrational.

And this is our answer.

And we're done!

Answer:

  -26, -25

Step-by-step explanation:

The average of the two is their sum divided by 2: -51/2 = -25.5. The average of consecutive integers is halfway between them.

Hence, one is -26 and one is -25.

valkas [14]

Answer:

Null and alternative hypotheses:

H0: p1 = p2

H1: p1 ≠ p2

To find the sample proportions, we have the following:

p'1 = \frac{x_1}{n_1} = \frac{113}{3180} = 0.0355

p'2 = \frac{x_2}{n_2} = \frac{157}{3168} = 0.0495

p' = \frac{(x_1 + x_2}{n_1 + n_2} = \frac{113 + 157}{3180 + 3168} = 0.0425

Calculate Z statistics:

z = \frac{(p1 -p2)}{\sqrt{(p'(1-p')*(\frac{1}{n1}+ \frac{1}{n2})}}

= \frac{(0.0355 - 0.0495)}{\sqrt{(0.0425*(1-0.0425) * (\frac{1}{3180} + \frac{1}{3168})}} = -2.764

Z = -2.764

P-value = 0.00285

The pvalue is low.

Since the pvalue is low, reject null hypothesis, H0.

Conclusion:

There is strong evidence that patients experiencing the primary outcome is different for those receiving the treatment compared to those without

You and a friend went to the movies.You spent half your money on tickets. Then you spent 1/4 of the money on popcorn, $2 on cand
bagirrra123 [75]

Answer:

We took $ 24 to the movies.

Step-by-step explanation:

Let total money be

On movies = Half of the money =\frac{x}{2}

On popcorn =  \frac{x}{4}

on candy = $2

On soda = $3

total money spent =  \frac{x}{2} +\frac{x}{4}+ 2+3+1

         x   =  \frac{x}{2} +\frac{x}{4}+ 2+3+1

x- \frac{x}{2} -\frac{x}{4} = 6

\frac{x}{1} -\frac{x}{2} - \frac{x}{4}  =6

    \frac{4x-2x-x}{4}  = 6\\          \frac{x}{4} =6\\x =24
