The table shows the results of rolling a number cube, with sides labeled 1 through 6, several times.
Free_Kalibri [48]

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

(a) Suppose one house from the city will be selected at random. Use the histogram to estimate the probability that the selected
Lera25 [3.4K]

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:

P(X

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:

P(\bar X)=P(z

Hence, the probability  that the mean value of the 40 houses is less than $500,000 is 0.9863

82 (3x+1)<br><br> Find the value of x
PolarNik [594]

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
