Answer:
f(-8) = 104
Step-by-step explanation:
f(t) = t^2 - 5t
Let t=-8
f(-8) = (-8)^2 -5(-8)
= 64 +40
= 104
<span>1/2r + 4= 3/4r - 3/2
1/2 = 2/4
3/2 = 6/4
re-write
2/4r + 4 = 3/4r - 3/4
2/4r - 3/4r = -3/4 - 4
-1/4r = -4 3/4
r = (-4 3/4) / (-1/4)
r =(-4 3/4) * (-4)
r = 76/4
r = 19</span>
Answer:
y = 6
Step-by-step explanation:
2(2y -12) = 0
a. Distribute the problem out
4y - 24 = 0
b. Add 24 to both sides to seperate the constants and the terms.
4y - 24 = 0
+24 +24
4y = 24
c. Divide 4 out of both sides to isolate y
y = 6
d. Plug the 6 back into the equation to see if the answer is correct.
2(2(6) -12) = 0
2(12-12) = 0
2(0) = 0
Hope this helps!
X % ==> $180.00
100% ==> $135.00
So : 180.00*100/135.00 = 133.33 %.

Answer:
Step-by-step explanation:
Let assume that Suppose the chance of contracting malaria is 10% for those who are not vaccinated ; (since the value) is not given.
Thus;
If the vaccine has no effect, risk of malaria for vaccine and no vaccine are equal to 0.1
Probability of not getting malaria if vaccinated or no vaccinated = 1 - 0.1 = 0.9
Malaria No Malaria Total
Vaccinated 100 * 0.1 = 10 100 * 0.9 = 90 100
No Vaccine 200 * 0.1 = 20 200 * 0.9 = 180 300-100 = 200
Total 20 + 10 = 30 90 + 180 = 270 300
If the vaccine cuts the risk by half, risk of malaria for vaccinated are equal to 0.1/2 = 0.05
Probability of not getting malaria if vaccinated = 1 - 0.05 = 0.95
Malaria No Malaria Total
Vaccinated 100 * 0.05 = 5 100 * 0.95 = 95 100
No Vaccine 200 * 0.1 = 20 200 * 0.9 = 180 300-100 = 200
Total 20 + 5 = 25 90 + 180 = 275 300
