Answer with Step-by-step explanation:
we are given a event of rolling as die several times:
Outcome: [1 2 3 4 5 6]
Number of times outcome occurred: [10 6 4 8 6 6]
We have to find the experimental probability of rolling a 1 or a 5
number of times 1 or 5 came up= 10+6=16
and total number of outcomes= 10+6+4+8+6+6= 40
P( rolling a 1 or a 5)=
number of times 1 or 5 came up/ total number of outcomes
= 16/40
= 2/5
Hence, the experimental probability of rolling a 1 or a 5 is:
2/5
Answer:
f(x)=290+30x
Step-by-step explanation:
the 290 is for the money initially put in, the 30 is for the thirty dollars, and the x represents the number of weeks.
Answer:
a. 0.71
b. 0.9863
Step-by-step explanation:
a. The mean of the distribution is given as $403,000 and the standard deviation is $278,000.
-To estimate the probability that a randomly selected house has a value less than $500,000:
Thus, the probability that a randomly selected house has a value less than $500,000 is 0.71
b. -since 40 is larger than or equal to 30, we assume normal distribution.
-The probability can therefore be calculated as:
Hence, the probability that the mean value of the 40 houses is less than $500,000 is 0.9863
Answer:
this equals 246x + 82
Step-by-step explanation:
We do this by doing distributive property.
This means to multiply the outside number of the parenthesis ₙ( ) to everything inside the parenthesis.
So 82·3x is 246x
Then 82·1
This equals all together 246x + 82
