Answer: 15.06
Step-by-step explanation:
Average points per game (mean) (m) = 22.5
Standard deviation (sd) = 6.2
Number of point scored in a game is 1.2 standard deviations below the mean, how many points below average was the value
1.2 standard deviations = (1.2 * value of standard deviation) = (1.2 × 6.2) = 7.44
Hence, 1.2 standard deviations below the mean equals :
Mean - 7.44
22.5 - 7.44 = 15.06
Hence, score = 15.06
Hello,
y=k(x+3/2)²-25/2
and -8=k*9/4-25/2==>9/4k=9/2==>k=9/2*4/9=2
y=2(x+3/2)²-25/2
x- intercepts:
y=0=2(x+3*2)²-25/2
==>(x+3/2)²=25/4
==>x=-3/2-5/2 or x=-3/2+5/2
==>x=-4 or x=1
(-4,0) and (1,0) are x intercepts
