Answer:
It is C because on 12 I can see 3.
Step-by-step explanation:
Answer:
y=18
Explanation:
input x=5
rule ——-> 4x-2
=4x5-2
=20-2
=18 {scrutinize}
output y=18
You need to use the binomial probability formula:
where:
n = total number of events = 10
k = number of events we are testing = 6
p = probability of event happening = 0.5
= 210×0.015625×0.0625
= 0.205078
Hence, the probability of getting 6 boys out of 10 births is
p = 0.205.
First you would divide by 2 in both sides
P/2 = l + w
Then you would subtract w from both sides
P/2 - w = l
This is the easiest method do isolate l
You can also distribute the 2 to ( l + w) first
P= 2l + 2w
Then subtract 2w from both sides
P - 2w = 2l
Then you would divide by 2
(P - 2w) / 2 = l
P/2 - w = l
$20
I got it by dividing 12 tickets÷3 which equals 4. Then I multiplies 4×$5= $20
