There is A Spinner That Have 8 Space 1-8 What Is The Probability That Te Spinner Will NOT Land On 5 or 8?
insens350 [35]

Answer:

\frac{3}{4}

Step-by-step explanation:

<u>Key skills needed: Probability, Possible Outcomes</u>

1) We are given a spinner --> With numbers: 1,2,3,4,5,6,7, and 8

That means there are 8 numbers on the spinner.

2) The problem asks what is the probability that the spinner will not land on 5 or the 8.

To calculate this --> \frac{acceptedoutcomes}{total}

3) The accepted outcomes are when the spinner lands on --> 1,2,3,4,6,7

That is 6 accepted outcomes.

4) The total outcomes is 8 (since there are numbers the spinner can land on).

5) Therefore, the answer would be \frac{6}{8}

\frac{6}{8} can be simplified into \frac{3}{4} as both the numerator (6) and the denominator (8) share a factor of 2.

6) With this --> \frac{3}{4} is the answer.

Determine the value of r so that a line through the points (r,3) and (5,-4) has a slope of -1/2
CaHeK987 [17]

\bf (\stackrel{x_1}{r}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-4}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-4-3}{5-r}=\stackrel{\stackrel{slope}{\downarrow }}{-\cfrac{1}{2}}\implies \cfrac{-7}{5-r}=\cfrac{1}{-2} \\\\\\ 14=5-r\implies 9=r
