4(5y-8-2) = 185-15
20y-32-8 = 170
20y-40 = 170
+40 +40
20y = 210
Divide both sides by 20
Y= 10.5
Answer: The equation is <em>s</em> = 350 + 60<em>s</em>, and given this equation, we can determine that the total savings after eleven weeks is $1,010.
Answer:
P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2
Step-by-step explanation:
Given that:
Total Number of cameras (n) = 8
Defective cameras = 4
X: number of defective cameras
For a binomial distribution :
P(x) = nCx * p^x * (1 - p)^(n - x)
Probability of success (p) on each trial is the same = (total number of samples / number of defective samples) = 8/4 = 0.5
If 2 samples are chosen at random :
Then, the binomial probability distribution will be :
P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2
Answer:
1,020
Step-by-step explanation:
First step.
Since he can read 21 1/4 pages in 1 and 1/4 hour then we got to know how many pages he can read in one hour right? so we need to divide.
Second step.
So we will need to divide 21 1/4 divided by 1 and 1/4 which will give us 17 which is the pages he will read in one minute.
Third step.
After you get that then we multiply it by the hour which is 60 minutes in an hour so,
60 x 17 = 1,020
Which gives us the answer
Hope that helps =)
The interval 44-47 has a frequency of 3 .
The interval 48-51 has a frequency of 4.
The interval 56-59 has a frequency of 1.
The given data set is:
42, 43, 46, 47, 47, 48, 49, 50, 51, 53, 55, 55, 59
The number lying in the interval 44-47 are :46, 47, 47
So the interval 44-47 has a frequency of 3.
The number lying in the interval 48-51 are :48, 49, 50, 51
So, the interval 48-51 has a frequency of 4.
The number lying in the interval 56-59 is: 59
So, the interval 56-59 has a frequency of 1.
