Answer: Shane collected more than 911 cans
Step-by-step explanation:
S is the number of cans that shane collected.
A is the number of cans that Abha collected.
We know that:
together collected more than 2000 cans
A + S > 2000
Abha collected 178 more cans that Shane:
A = S + 178
Now, we can replace this equation in the inequality and get:
A + S > 2000
S + 178 + S > 2000
2*S > 2000 - 178 = 1822
S > 1822/2 = 911
This means that shane collected more than 911 cans.
(33x+99)+1(−44x+88)
(33x+99)(44x+88)
-33x to 44x and get 11x then subtract 88 to 99 and get 11 the answer should be one
Answer:
ok....
Step-by-step explanation:
Answer:
Mean and Variance of the number of defective bulbs are 0.5 and 0.475 respectively.
Step-by-step explanation:
Consider the provided information,
Let X is the number of defective bulbs.
Ten light bulbs are randomly selected.
The likelihood that a light bulb is defective is 5%.
Therefore sample size is = n = 10
Probability of a defective bulb = p = 0.05.
Therefore, q = 1 - p = 1 - 0.05 = 0.95
Mean of binomial random variable: 
Therefore, 
Variance of binomial random variable: 
Therefore, 
Mean and Variance of the number of defective bulbs are 0.5 and 0.475 respectively.
