Answer:
1.)
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
Conditional probability ;
0.47
Step-by-step explanation:
Let :
E = Excellent ; A = Average ; N = not up to standard
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.
The probability that Leo is coming :
Leo ; Excellent = 0.7
Leo ; Average = 0.3
Leo; Not up to standard = 0.2
Hence, probability they Leo is coming :
(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)
0.35 + 0.06 + 0.06
= 0.47
First, distribute the negative sign and get -y + 7 = 14
then subtract 7 from both sides and get -y = 7
Divide both sides by -1 and get y = -7
Hope this helps :)
Easy!
Wouldn’t it just be
(With your formula of volume/rate=time)
250mL/2 hours=
125mL a hour
2.083(three is repeated)mL a minute
0.03472(two is repeated)mL a second
At least that’s what I think
I think C. Hope this help! I don’t wanna be rude but can I have brainliest please???!
What this question is asking us is
A) From -40C to 5 0c How much did it rise
The formula for this would be
Risen Temperature - Initial Temperature
The risen temparauture is 5 so we plug the 5 in first then the 4 so it would look like
5-(-4)=9
And remeber when you have 2 negatives it becomes a positie, 5+4=9
The asnwer for A is 9 degress
B) The tempurater then fell by 7 degress from 5 so we just have to do
5 - 7
which is -2 Celcius
