Answer:
Step-by-step explanation:

can be factored out as (-x-6)(x-6)
x-intercepts are: +6 and -6
represents the two ends of the rainbow
y-intercept: y=36
represents the highest point of the rainbow

Q3 = 37
Max = 40
Answer:
Step-by-step explanation:
Let number of large pizzas be l and number of small be s.
<u>Then we have equations:</u>
- l + s = 100
- 16l + 11s = 1550
<u>From the first equation, we get l = 100 - s and substitute in the second equation:</u>
- 16(100 - s) + 11s = 1550
- 1600 - 16s + 11s = 1550
- 5s = 1600 - 1550
- 5s = 50
- s = 10
Number of small pizzas is 10
19% of 30
19 / 30 = 5.7
19 percent of 30 is approx. 5.7

Answer:
The null hypothesis is: 
The alternative hypothesis is: 
Step-by-step explanation:
At the null hypothesis, we test if the mean is equal to a certain value.
At the alternate hypothesis, we test if the mean is less than, more than, or different from the value tested at the null hypothesis.
The tuft bind strength of a synthetic material used to make carpets is known to have a mean of 100 lb and standard deviation of 20 lb.
This means that the null hypothesis is: 
Could it be that the average tuft strength is above 100 lb?
The world above means that the appropriate alternative hypothesis is:
