Answer:
a. F(x)=10x-1 , the value of F(-2) is
F(-2)=10(-2)-1
f(-2)= -20-1
f(-2)= -21
b. g(x)= -5x+13 , the value of g(1)
g(1)= -5(1)+13
g(1)= -5+13
g(1)= 8 or +8
c. h(x)=
-x-12 , the value of h(3) is
h(3)=
-3-12
h(3)=9-3-12
h(3)= -6
Step-by-step explanation:
Answer:
84%
Step-by-step explanation:
Henry completed a total of 50 questions. From these 50 he predicted 36 were right and this means he also predicted that 14 were wrong (50-36 = 14). From these predictions 5 out of 36 from the ones that he predicted were right were actually wrong and 3 of the 14 questions (14-11 = 3) he predicted were wrong were actually right. Meaning in total he wrongly predicted 8 questions which means he predicted 42 correctly ...
42 / 50 = 0.84 = 84%
Therefore, Henry's prediction accuracy is 84%
that is the formula that you use to find x then after you find it put it in the formula for Qsr then you get you answer
