Cost of the skateboard = $77.99
Amount that he already has = $20
$77.99 - $20 = $57.99
He still needs <u>$57.99</u>
He earns $6 for every lawn he mows.
$57.99 ÷ 6 = 9.65
He needs to move <u>10 lawns </u>to earn that $57.99.
He can mow 3 lawns a weekend.
10 ÷ 3 = 3 1/3
He needs to work on <u>4 weekends</u> to mow the 10 lawns.
Answer: It will take him 4 weekends to save enough to buy the skateboard.
the maximum height is the y-value of the vertex.
h(x) = -2x² + 20x + 48
<em> a=-2, b=20, c=48</em>

h(5) = -2(5)² + 20(5) + 48
= -50 + 100 + 48
= 50 + 48
= 98
Answer: 98 meters
Answer:
Step-by-step explanation:
The probability is obtained by calculating the z score,
<u>(pˆD−pˆE) - (PD - PE)</u>
0.0914
<u>10.1917-0.1 </u>
0.0914 = 1.0029
P(z > 1.0029) = 1 - P(z ≤ 1.0029)
The probability is obtained from the z distribution table,
P(Z > 1.0029) = 1-0.8420 = 0.1580
I guess itz B because with the rest, a number can be added to get exactly 50. Example C. y= 50x. x could be 1 which is still 50 and D. y=50-x and x could be 0 which is still 50 whiles A. y=50 remains 50
