Step-by-step explanation:
If you pick three burritos at random, find the probability of the given event. (Round your answer to three decimal places.)
Given that there are 14 orders at the ratio by of:
6 with hot peppers
8 without hot peppers
At most two have hot peppers.
Binomial Problem with n = 3 ; p(hot) = 6/8
P(0<= x <=2) = 1 - P(x = 3)
= 1 - (6/8)^3
= 1 - ( 3/4 )^3
= 1 - ( 27/64 )^3
= 1- (37/64)
= 1 - 0.421875
= 0.578125
= 0.578
Answer:
Slope is the change in y over the change in x. Just subtract and simplify the fraction.
Step-by-step explanation:
(-3 - 4)
______
(-2 - 6)
Let's do it step by step. In the first step eliminate the two parenthesis, for which you need to use the rule of multiplication of signs: the multiplication of two equal signs leads to positive sign, the multiplication of two different signs leads to negative sign. So -(-8) = +8 and -(-14) = +14. and 19 -(-8) - (-14) - 19 + 8 + 14 = 41. The answer is the option C. 41<span>.</span>
X+y=40
25x+40y=1375
25x+40(40-x)=1375
25x+1600-40x=1375
-15x=-225
X=15
15+y=40
Y=25
