Make sure you check this because i do make mistakes.
10 x 4 = 40
75 - 40 = 35
So josiah has 35 dollars to spend for things other than tickets.
35 - 3 = 32 (for the service fee)
So josiah has 32 dollars to spend on popcorn
32/5 = 6.4 but you cant have half a bag of popcorn so
6 bags
Hello,
2x²+x-14=0
Δ=1+4*14*2=113
x=(-1-√113)/4=-2,8839...≈-2.88
or x=(-1+√113)/4=2,40753≈2.41
Nathan has an infection and he needs to be treated with penicillin
But there’s a 75% probability of him being allergic to penicillin
And to test if the skin reacts to penicillin, the test is 98% accuracy
So even if he has the allergy the test is only 98% accurate of identifying the allergy
Therefore we are asked to find the probability of both these events happening
Event 1 and event 2 both should happen then. When the ‘and’ function is used in probabilities then the probabilities of both events happening should be multiplied
Therefore probability that Nathan has the allergy and test predicts it is
= 75% x 98% = 0.735
The answer is D. 0.735
If the last one is supposed to be 7(8+3), it would be equivalent to 56+21
