I don't know. I'll have to figure it out.
Probability =
(number of successful possible results) / (total possible results) .
Total possible results for the spinner . . . 8
Successful ones (getting a 1, 2, 3, 4, or 5) . . . 5
Theoretical probability = 5/8 .
So you expect (5/8 of 150) spins to be successful.
(5/8 times 150) = 93.75
Yes !
93 or 94 is a good answer.
Answer: 2 hr.
Explanation: Think back to rate of change. <em>d</em> = <em>rt</em>, <em>r</em> = <em>d/t</em>, <em>t</em> = <em>d/r</em>. In this case, we will be using <em>d</em> = <em>rt</em>. Mph would be <em>r</em>, rate, so you would categorize 15 mph and 8 mph under rate. <em>t</em> should represent the time each cyclist traveled. Tracey's and Emma's distance, <em>d</em>, would be the same as their mph, hence Tracey's being 15<em>t</em> and Emma's would be 8<em>t</em>. When you add Tracey's distance plus Emma's distance, you end up with 46 mi. Now, you need to combine like terms, which should look like 15<em>t</em> + 8<em>t </em> = 46. Add 15 and 8 to get 23, so it should be 23<em>t</em> = 46 now. Then, divide both sides of the equation by 23 and now you should have your answer, <em>t</em> = 2 hr.
To solve the problem you have to take 682,494 and divide it be 20 because 1 in every 20 accidents are caused by that. So, if you divide that you will see what 1 in every 20 is so the equation would be 682,494 div by 20 which will give you 34,124.
Answer:
b
Step-by-step explanation:
The first thing is the slope
y = 1/2 x + b is the new line. Now we must solve for b
2 = 1/2 (-2) + b
2 = -1 + b
3 = b
The new line is
y = 1/2 x +3
