Answer: number 5 is A number 6 is B
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
Since this equation is already in slope intercept form you can see its 7.
The formula: y=mx+b is a formula to identify the slope and y-intercept.
The m indicates the slope and the b indicates the y-intercept.
Answer:
-11
Step-by-step explanation:
m + n = - 2
4(m + n) = - 2(4) (multiplying both sides by 4)
4m + 4n = - 8
4m + 4n - 3 = - 8 - 3 (Subtracting 3 from both sides)
4m + 4n - 3 = - 11
Step-by-step explanation:
1.)20x + 100 = 1440
-Let the number of couples be x. So, the total amount paid by all the couple’s are $20x. School paid $100 as security, so the total amount paid is
$ (20x + 100)
2.) 20x = 1440 - 100 ⇒ 20x = 1040
X = 52
3. ) The security money is $100, so the couples paid $1440- 100 = $1040 in total. As the couples paid $ 20 each than- 
= 52
Answer:
probability of a crash with at least one fatality if a driver drives while legally intoxicated (BAC greater than 0.09) = 0.001932
Step-by-step explanation:
P(BAC=0|Crash with fatality)=0.625
P(BAC is between .01 and .09|Crash with fatality)=0.302
P(BAC is greater than .09|Crash with fatality)=0.069
Let the event of BAC = 0 be X
Let the event of BAC between 0.01 and 0.09 be Y
Let the event of BAC greater than 0.09 be Z
Let the event of a crash with at least one fatality = C
P(X|C) = 0.625
P(Y|C) = 0.302
P(Z|C) = 0.069
P(C) = 0.028
probability of a crash with at least one fatality if a driver drives while legally intoxicated (BAC greater than 0.09) = P(C n Z)
But note that the conditional probability of probability that a driver is intoxicated (BAC greater than 0.09) given that there was a crash that involved at least a fatality is given by
P(Z|C) = P(Z n C)/P(C)
P(Z n C) = P(Z|C) × P(C) = 0.069 × 0.028 = 0.001932
Hope this Helps!!!
