If I'm right, 14/3 m and 2/3 m are like terms, so -14/3m+2/3m= -12m. Your answer is then 12-12m
Answer:
5 : 3
Step-by-step explanation:
Given in the question that,
total number of animal feet = 26
number of pig's feet = 20
number of chicken's feet = 6
As we know that pig have four legs and chicken have 2 legs so,
number of pigs in the farm = 20/4 = 5
number of chickens in the farm = 6/2 = 3
Questions says that there are 8 heads so we can confirm our calculations as
<h3>5 + 3 = 8</h3><h3 />
The ratio of the number of pigs to the number of chickens is
<h3>5 : 3 </h3>
Step-by-step explanation:
We define 3 events
A = event that driver is above speed limit
B = event that driver is below limit
T = event that the gun detected him
At 95%
P(A) = 1-0.95 = 0.05
P(B) = 0.95
P(T|A) = 0.98
P(A|T) = 0.02
P(T|B) = 1-0.99 = 0.01
P(B|T) = 0.99
1. For answer a
P(TnA) = P(A) x P(T|A)
= 0.05 x 0.98
= 0.049 is the probability gun detected speeding and the driver was speeding
2. For answer b
P(TnB) = P(B) x P(T|B)
= 0.95x0.01
= 0.0095 is probability that gun deects speeding and driver was not speeding
3. For answer c
We solve this using bayes theorem
P(B|T) = P(B) x P(T|B) / (P(B)*P(T|B)) + (P(A) +P(T|A))
= 0.095x0.01 divided by (0.95x0.01)+(0.05*0.98)
= 0.0095 divided by 0.0585
= 0.16239
= 0.1624 to 4 decimal places.
Answer:
i just forgot sorry
Step-by-step explanation:
First Q.
If y = 6 and x = 10, then what's x if y = 18
y / x = 6 / 10 = 0.6
y / x = 18 / x = 0.6
x = 0.6 * 18
x = 10.6
Second Q.
If y = 22 and x = 8, then what's y if x = -16
y / x = 22 / 8 = 2.75
y / x = y / -16 = 2.75
y = 2.75 * -16
y = -44
