$sin30 = \frac{o}{h} \\ sin30 = \frac{5}{x} \\ x = \frac{5}{0.5} \\ x = 10$

${10}^{2} + {10}^{2} = {y}^{2} \\ 100 + 100 = {y}^{2} \\ 200 = {y}^{2} \\ \sqrt{200} = y \\ 14.14 = y\\$

Which two numbers on the number line have an absolute value of 1.75? Select the location of both numbers on the number line

hram777 [196]

Solution

To find Which two numbers on the number line have sn

absolute value of 1.75 .

Absolute value means " how far a number is from

zero " .

"1.75" is 1.75 away from zero .

and " -1.75" is also 1.75 away from zero .

i.e

| 0 - 1.75 | = 1.75

| 1.75 - 0 | = 1.75

So , the absolute value of "1.75" is 1.75

similarly , absolute value of "1.75" is 1.75 .

Hence , the two numbers are -1.75 and 1.75 .

Greenville County, South Carolina, has 461,299 adult residents, of which 59,969 are 65 years or older. A survey wants to contact

Salsk061 [2.6K]

The proportion would be the number of the sample (x) over the population size (n)

Here we have x = 59,969 and n= 461,299

P = x/n = 59969/461299

P = 0.13

I’m having a hard time with this. Is this a typo by the teacher or should I actually be looking for a size?

Lemur [1.5K]

Step-by-step explanation:

There are 12 games in the population. You need to use a random number generator to choose 2 of these games.

RandomSample[{1,2,3,4,5,6,7,8,9,10,11,12},2]

Let's say the first sample you get is {1,5}. That corresponds to game times of 8 minutes and 7 minutes. The mean game time for that sample is 7.5 minutes. So the first row in your table would be:

$\left[\begin{array}{ccc}Sample&List\ of\ Game\ Times&Mean\ Game\ Time\\1&8,7&7.5\end{array}\right]$
