Answer:
12.5
Step-by-step explanation:
If the number of workers injured in each accident is i<em>ndependent </em>of the number of accidents that occur, <em>then the expected number of workers injured in a week equals the expected number of accidents per week times the expected number of workers injured in each accident.
</em>
But the expected number of workers injured in each accident is precisely the average or mean, so
<em>Expected number of workers injured in a week = 5*2.5 = 12.5.
</em>
Or in other words, in 10 weeks there will probably be 125 workers injured.
Answer:
x<−15
Step-by-step explanation:
Let's solve your inequality step-by-step.
15x<−3
Step 1: Multiply both sides by 5.
5*(15x)<(5)*(−3)
x<−15
Answer:
D. 8/15
Step-by-step explanation:
4/5 = 2/3 +1/3
We need to multiply by 6 to find answer as 3 is a divider of 6
4 x 6 =24
5 x 6 =30
24/30
Then we find 1/2 of 30 and add this to make 3/3
Just like 1/2 of 2 = 1 and 2+1 = 3
30 / 2 = 15
15 + 30 =45
The answer is 24/45
We then reduce this fraction by 3 as 6 + 8 do not divide into 45
24/45 = 8/15
The answer is 8/15
Answer:
U' = (-1,2)
V' = (2,2)
W' = (0,-2)
Explanation:
The given dilation factor is 1/4
This means that each coordinate point is multiplied by 1/4 to get its dilated image.
For point U:
Point U = (-4,8)
x coordinate of U' = 1/4 * x coordinate of U
x coordinate of U' = 1/4 * -4 = -1
y coordinate of U' = 1/4 * y coordinate of U
y coordinate of U' = 1/4 * 8 = 2
This means that: U' = (-1,2)
For point V:
Point V = (8,8)
x coordinate of V' = 1/4 * x coordinate of V
x coordinate of V' = 1/4 * 8 = 2
y coordinate of V' = 1/4 * y coordinate of V
y coordinate of V' = 1/4 * 8 = 2
This means that: V' = (2,2)
For point W:
Point W = (0,-8)
x coordinate of W' = 1/4 * x coordinate of W
x coordinate of W' = 1/4 * 0 = 0
y coordinate of W' = 1/4 * y coordinate of W
y coordinate of W' = 1/4 * -8 = -2
This means that: W' = (0,-2)
Hope this helps :)
Store 1: $26.62/36=0.74 per oz.
Store 2: $22.42/28=0.80 per oz
So store 1 is .06 cents cheaper than store 2
