Z = ( X - Mean ) / SD
z = ( 646 - 597 ) / 39
z = 49/39 = 1.25
With the z-score table:
for z = 1.25, p = 0.8944 ( probability that the cost will be lower than $646 )
1 - 0.8944 = 0.1056
Answer: <span>The probabilit</span>y is 0.1056
Yo sup??
total distance travelled by Janae =sum of distance on the 2 semicircles+ sum of the distances on the 2 track
=2πr+2*l
l=3 miles
r=1 mile
So,
total distance=2*3.14*1+2*3
=6.28+6
=12.28
=12.3 miles
Therefore the correct answer is option D
Hope this helps
Answer:
y = 5/2x - 5
Step-by-step explanation:
Step 1: Write equation
5x - 2y = 10
Step 2: Solve for <em>x</em>
- Subtract 5x on both sides: -2y = 10 - 5x
- Divide both sides by -2: y = -5 + 5/2x
- Rewrite: y = 5/2x - 5
