Answer:
Answer is C
Step-by-step explanation:
1) solve for 3/5x-3 = 3/5
= 8/5 or 1.6
so solve for x in ABCD and see what matches.
A) 24/25 or 0.96
This does not match
B) 17/15 or 1.13
This does not match
C) 8/5 or 1.6
THIS MATCHES
D) 5/8 or 0.625
This does not match
STEP BY STEP ON PAPER:
Answer:
15x = y
Step-by-step explanation:
15 times the gallons of gas = miles
15x = y
A) In 1st Figure, Blue boxes means unit of diet soda = 8
Green boxed is regular sods = 4
Total Boxes = 12
Value of 1 Box = 888/12 = 74
Now, We know, we have 74 soda in each box, and 8 boxes of diet soda, so the number of diet soda = 74 * 8 = 592
In short, Your Answer would be: 592B.) Now, In 2nd figure, You can see
Red boxes mean Short sleeve short which is = 3
Green means Long sleeve = 7
Total Boxes = 10
Value of 1 Box = 460/10 = 46
Now, we know we have 46 shirts in each boxes and their is 3 boxes of short sleeves.
So, Number of Short sleeves = 46 * 3 = 138
In short, Your Answer would be: 138Hope this helps!
The mean of the given sample data is 210, and the standard deviation is 7.937.
Given size 'n' = 300
The population proportion 'p' = 0.7
Let 'x' be the random variable of the binomial distribution
a) mean of the binomial distribution = n p = 300 × 0.7
μ = 210
b) variance of the binomial distribution
⇒ n p q
⇒ 300 × 0.7 ×0.3
⇒ σ² = 63
The standard deviation of the binomial distribution:
⇒ √n p q = √63 = 7.937
Thus, the mean of the given sample data is 210, and the standard deviation is 7.937.

The question seems to be incomplete the correct question would be:
describe the sampling of p hat. Assume that the size of the population is 25000 n= 300 p=0.7 a) Determine the mean of the sampling distributionb) Dtermine the standard deviation of the sampling distribution
