Answer:
(k+3)(k+4)
The zeros are -3 and -4
Step-by-step explanation:
k2+7k+12
The middle number is 7 and the last number is 12.
This means we need two numbers that:
Add together to get 7
Multiply together to get 12
to fit in this equation (k+_)(k+_)
in this equation, it would be 3 and 4
3+4 = 7
3*4 = 12
Now we fill in the blanks to get
(k+3)(k+4)
To get the zeros, use the equations
k+3=0 and k+4=0
You end up with
k=-3 and k=-4

Coach De Leon purchases sports equipment. Basketballs cost $20.00 each, and soccer balls cost $18.00 each. He had a budget of $150.00.
Answer:
18s+20b<_150
Step-by-step explanation:
He can buy 5 basketballs and 2 soccer balls. This equation is correct because 18x2 is 36 and 20x5 is 100. So that will be a total of $100. This makes the equation 100<_150. You can infer that this equation is true.

A. (–4 + i) + 4i = –4 + (i + 4i)
Step-by-step explanation:

Have a great day y'all :)
(–4 + i) + 4i = –4 + (i + 4i) is the associative property of addition. Thus, option A is correct.
What is the associative property of addition?According to the associative property of additionally, whenever at least three figures are added together, the outcome is unaffected by the sequence in which the individual numbers are added.
In the first given condition is is stated:
(–4 + i) + 4i = –4 + (i + 4i)
-4 + i + 4i = -4 + i + 4i
5i - 4 = 5i - 4
As the LHS = RHS, the property is said to be valid for the associative property of addition.
Therefore, option A is the correct option.

A trade magazine routinely checks the drive-through service times of fast-food restaurants. Upper A 95% confidence interval that results from examining 771 customers in one fast-food chain's drive-through has a lower bound of 175.2 seconds and an upper bound of 178.2 seconds. What does this mean?
Answer:
Step-by-step explanation:
The confidence interval is an interval that determines an unknown population parameter. It showcases the probability that a particular population parameter will fall within this interval. As the sample size reduces, the width of the confidence interval usually increases.
What the given question mean is that one can still be 95% confident that the mean drive-through service times of this fast-food chain is between 175.2 seconds and 178.2 seconds.

Find the slope!! Please
Answer: The slope is undefined
Step-by-step explanation:
Answer:
undefined
Step-by-step explanation:
slope equation is y2-y1/x2-x1
use points (-2,2) and (-2,-2)
insert values into equation: -2-2/-2+2
simplify: -4/0
if the zero is on top of the fraction, then the slope is zero but since the zero is on the bottom, the slope has to be undefined

The school carnival committee sold a total of 200 tickets for the grand prize drawing. Sue bought enough tickets so that she had a 20 percent chance of winning the grand prize. How many tickets did Sue buy?
Answer:
40 tickets
Step-by-step explanation:
Given that:
Total tickets sold = 200
Sue's chances of winning = 20% = 0.2
Number of tickets bought by Sue :
P(winning) = 20%
P(winning) = required outcome / Total possible outcomes
Required outcome = number of tickets bought by Sue
Total possible outcomes = total number of tickets sold
0.2 = x / 200
x = 0.2 * 200
x = 40
