Answer:
Number = 15.
Step-by-step explanation:
Given : If you multiply a number by 3 and then subtract 5, you will get 40.
To find : what is the number.
Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.
According to question :
Let the number = x
Multiply is with 3 = 3x
Subtract 5 from it we get 40 .
3x -5 = 40
On adding both sides by 5
3x = 45 .
On dividing both sides by 3
x = 15.
Therefore, Number = 15.
Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.
Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5
Therefore, we have:

Let x be the number calls that reach to live person.
We have to find 
Using the binomial probability distribution, we have:



Therefore, the probability that none of them reaches a live person is 0.3277
Find the unit rate

Answer: 124 strikeouts per year
Answer:
If the number being multiplied by -1 is positive it just turns it negative, but if the number being multiplied by -1 is also negative it becomes positive. Basically if flips the sign.
Step-by-step explanation:
EX) 25 x -1 = -25
EX) -25 x -1 = 25
The linear inequality
will not have a shared solution set with the graphed linear inequality. the correct option is D.
<h3>What is inequality?</h3>
Inequality is defined as the relation which makes a non-equal comparison between two given functions.
On a coordinate plane, a solid straight line has a negative slope and goes through (-2, 2) and (2, -8).
m = (-8 -2)/ (2 +2)
m = -10/ 4
m = -5/2
The line has an equation of y greater-than-or-equal-to negative five-halves x minus 3.

The linear inequality
will not have a shared solution set with the graphed linear inequality.
Thus, the correct option is D.
