Answer:
Your answer is -6 over 15
Step-by-step explanation:
Use the formula y2-y1 over x2- x1 to solve the slope. Then plug in your numbers. It would be 1- 7 over 10 - (-5). This equals -6/15, which would be the slope.
Answer:
270 pounds
Step-by-step explanation:
half of 12 is 6, so 18. Then you take half of 180 and add to 180
Multiply each X by its corresponding probability P, then add up them up.
E[X] = 3•0.2 + 4•0.1 + 5•0.25 + 7•0.05 + 9•0.4
⇒ E[X] = 6.2
<em>1/6 = 0.16 acres in 8 minutes. </em>
<em>--</em>
<em>0.16 ÷ 8 = 0.02 acres mowed in 1 minute.</em>
<em>--</em>
<em>(60 minutes in an hour)</em>
<em>0.02 x 60 = 1.2 acres mowed in an hour.</em>
<em>-- </em>
<em>1.2 is equal to 1 1/5, and jami needs to mow 1 1/2 acres.</em><em> so no, jami cannot mow 1 1/2 acres in an hour.</em>
