Answer:
Step-by-step explanation:
(a). The median number of hours spent on Math was about 2.9 ;
M + s = 10 or s = 10 - m
<span>3m + 2s = 23 </span>
<span>substitute first equation into second equation: </span>
<span>3m + 2(10 - m) = 23 </span>
<span>3m + 20 - 2m = 23 </span>
<span>m = 3 </span>
<span>using first equation: </span>
<span>s = 10 - 3 = 7 </span>
<span>check using second equation: </span>
<span>3(3) + 2(7) = 23 </span>
<span>9 + 14 = 23 checks </span>
<span>He hit 7 stationary and 3 moving targets.</span>
Answer:
y= -11/144(x-8)^2+6
Step-by-step explanation:
This equation can be represented in vertex form, which is:
y=a(x-h)^2+k
If we plug in 8 as h and 6 as k we get the following equation:
y=a(x-8)^2+6
Now we have to plug in x and y. We can use the other point (-4,-5) and plug it into the equation and get:
-5=a(-4-8)^2+6
Once we solve this we get a= -11/144
Now we have to plug in -11/144 into the original equation to get
y = -11/144 (x-8)^2 + 6
