With this function you are given 2 x's and all we have to do is plug those X's into the function so
f(-1)=4*7^-1
7^-1 is 1/7
times 4 = 4/7
f(2)=4*7^2
7^2=49 *4 = 196
You need to foil, The answer is D
Answer:
There is 55% probability that I order both the sandwich and soup
Step-by-step explanation:
P(sandwich) = 0.8
P(Soup) = 0.7
P(neither sandwich nor soup) = 0.05
P(sandwich or soup) = 1 - P(neither sandwich nor soup)
P(sandwich or soup) = 1 - 0.05 = 0.95
P(Sandwich & Soup) = x
P(Sandwich only) = 0.8 - x
P(Soup only) = 0.7 - x
P(sandwich or soup) = P(Sandwich only) + P(Soup only) + P(Sandwich & Soup)
Note that P(neither sandwich nor soup) has already been used to get the P(sandwich or soup) and should not be included in the above formula. Don't make that mistake!
0.95 = 0.8 - x + 0.7 - x + x
0.95 = 1.50 - x
x = 1.50 - 0.95
x = 0.55
There is 55% probability that I order both the sandwich and soup
Answer:
10.8 inches
Step-by-step explanation:
This is most likely correct because if it is 2.5 and 3 end root then you could probably multiply and ad an get your answer.
