Answer

6 and 10

Step by step explanation

a distance of 2 units from 8 on a number line

we need to find out the numbers that are 2 units from 8 on the number line

To find out the numbers we need to subtract and add 2 from 8

8+2=10

8-2=6

10 is 2 units from 8 on the right side

6 is 2 units from 8 on the left side

So, 6 and 10 are 2 units away from 8 on the number line.

Please help me with this, it’s due in an hour
Elena-2011 [213]
#3. For each hour worked, the employee makes $15/hour. This is true for every hour he works, so if he works for 4 hours he will make $60.

#4. For every second, the hot air balloon increases height by 5 feet.

#5. X&Y are proportional because for every hour, 5 feet are gained. Thus, after 7 hours, 35 feet are gained.

Thats all i have time to do right now. Good luck :)

Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to fi
mihalych1998 [28]

Answer:

P(X = 3) = 0.1442

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

n = 7, p = 0.65

We have to find P(X = 3).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{7,3}.(0.65)^{3}.(0.35)^{4} = 0.1442
