Harlamova29_29 [7]3 years ago
4 0

Step-by-step explanation:

Here n = 8 (even number)

\therefore \:  \frac{n}{2}  =  \frac{8}{2}  = 4 \\  \\\&\:\:   \frac{n}{2}  + 1 = 4 + 1 = 5 \\  \\ hence \:  \\ median = \frac{ {4}^{th} term +  {5}^{th} term}{2}  \\  \\  \therefore \:  49 =  \frac{x - 1 + x + 1}{2}  \\  \\  \therefore \:  49 =  \frac{2x}{2} \\  \\  \therefore \:  49 = x \\  \\  \huge \purple { \boxed{\therefore \: x = 49}}

Calculate the length of the diagonal of a rectangle whose sides measure : (a) 12 meters and 48 meters (b) 11 centimetres and 60
Serggg [28]
When solving this problem, you need to imagine the diagonal line through the rectangle. This makes two triangles which you can use the pythagorean theorem for. 12 squares plus 48 squared equals 2,448. Find the square root of that at it will be your answer (I don’t have the time to figure it out). 11 squared plus 60 squared is 3,712. Square root tbd... add the label and you’re finished!

<h2><u>DISTRIBUTIVE PROPERTY</u></h2>

The distributive property indicates that multiplying a number by the sum of two addends is equal to multiplying each addend individually by the number and then adding the products together.

In general terms:

<h3>m(n + p) = mn + mp</h3>

‎      ‏‏‎

<u>In this exercise</u>:

Let's apply the distributive property:

\mathsf{2(3w - 5y)}

= \mathsf{2(3w) - 2(5y)}

= \boxed{\mathsf{6w - 10y}}

‎      ‏‏‎

<h3><u>Answer</u>: 6w - 10y</h3>

One survey showed that among 785 randomly selected subjects who completed four years of college, 18.3% smoke and a 98% confidenc
Valentin [98]

Answer

a. True

Step-by-step explanation:

Based on this survey we estimate that about 18.3\% of the college students smokes. And a 98\% confidence interval is [15.1\% ; 21.6\%].  So we know that our estimative for the smoking rate is in the confidence interval with 98\% certainty. We also know the estimative for the smoking rate in the general population is 27\%. So we can write the two possible hypothesis:

H_0 = Smoking rate is equal to 27\%.

H_1 = Smoking rate is not equal to 27\%.

We will reject the null hypothesis (H_0) if the estimate doesn't fall into the confidence interval for the college students smoking rate.

Since this condition holds we reject the null hypothesis. So with 98\% certainty we say that the smoking rate for the general population is different than the smoking rate for the college students.
