Answer:
Option BStep-by-step explanation:
Definition of constants: Contants are numbers that have no variables.
To find the constants of the expression 7r - 3 + 2s + 5, simply look for numbers without variables. We can see that the constants are -3 and 5, which matches Option B.
Hence, Option B is correct.

Anything positive in n will be a negative on the right and that will always be less than the left side
But you put a negative on the left and it will be positive and also will minus from the right
So -1 will work because 80>3
So -2 will work because 79>6
So -3 will work because 78>9
So -4 will work because 77>12
So -5 will work because 76>15
So -6 will work because 75>18
But you see at some point this will not be a true statement so then you answer will be these negative numbers and all positive numbers

A botanist has developed a new hybrid cotton plant that can withstand insects better than other cotton plants. However, there is some concern about the germination of seeds from the new plant. To estimate the probability that a seed from the new plant will germinate, a random sample of 3000 seeds was planted in warm, moist soil. Of these seeds, 2470 germinated.
a. Use relative frequencies to estimate the probability that a seed will germinate. What is your estimate?
b. Use relative frequencies to estimate the probability that a seed will not germinate. What is your estimate?
c. Either a seed germinates or it does not. What is the sample space in this problem? Do the probabilities assigned to the sample space add up to 1? Should they add up to 1? Explain.
1. Yes, because they cover the entire sample space.
2. Yes, because they do not cover the entire sample space.
3. No, because they cover the entire sample space.
d. No, because they do not cover the entire sample space.
d. Are the outcomes in the sample space of part (c) equally likely?
Answers
Answer:
a. The estimate of the probability that a seed will germinate is:
82% (0.82)
b. The estimate of the probability that a seed will not germinate is:
18% (0.18)
c. The sample space is 2.
1. Yes, because they cover the entire sample space. The probabilities assigned to the sample space add up to 1 (0.82 +0.18).
They should always add up to one. Probability summed cannot exceed 1.
Step-by-step explanation:
a) Data and Calculations:
Sample = 3,000 seeds
Germinated seeds = 2,470
Non-germinated seeds = 530 (3,000 - 2,470)
Probability of a seed germinating = 2,470/3,000 = 82% approx.
Therefore, the probability of a seed not germinating = 18% (100 - 82) or (530/3,000)
Question
A football team sold raffle tickets to raise money for the upcoming season. They sold three different types of tickets:
premium for $8, deluxe for $3, and regular for $1. The total number of tickets sold was 155, and the total amount of money
from raffle tickets was $409. If 19 more deluxe tickets were sold than premium tickets, how many premium tickets were
sold?
Answers
9514 1404 393
Answer:
24
Step-by-step explanation:
Let p, d, r represent the numbers of premium, deluxe, and regular tickets sold, respectively.
p + d + r = 155 . . . . . . . number of tickets sold
8p +3d +r = 409 . . . . . revenue from tickets sold
d - p = 19 . . . . . . . . . . . relation between deluxe and premium tickets
Using the third equation, we can substitute d=19+p in the other two equations.
p + (19+p) +r = 155
8p +3(19+p) +r = 409
Subtracting the first of these equations from the second, we get ...
(11p +r +57) -(2p +r +19) = (409) -(155)
9p = 216 . . . . . . subtract 38 and simplify
p = 24 . . . . . . . . divide by 9
24 premium tickets were sold.

A community college has a math placement exam that has a mean of 65 and a standard deviation of 8.2. If a student takes the exam and scores in the lower 2.5%, they are eligible for a free intensive course to help them succeed in their math class. Assume that the exam has a normal distribution. What is the score that cuts off the bottom 2.5%
Answers
Answer:
The score that cuts off the bottom 2.5% is 48.93.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 65, \sigma = 8.2[/tex]
What is the score that cuts off the bottom 2.5%
This is X when Z has a pvalue of 0.025, so X when Z = -1.96.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.96 = \frac{X - 65}{8.2}[/tex]
[tex]X - 65 = -1.96*8.2[/tex]
[tex]X = 48.93[/tex]
The score that cuts off the bottom 2.5% is 48.93.

road bike: $650mountain bike: $700Step-by-step explanation:
If r is the cost of a road bike, then the cost of a mountain bike is r+50. The total cost of the 7 bicycles is ...
4r +3(r+50) = 4700
7r +150 = 4700 . . . . . . eliminate parentheses
7r = 4550 . . . . . . . . . . . subtract 150
r = 650 . . . . . . . . . . . . . divide by 7; price of a road bike
r+50 = 700 . . . . price of a mountain bike
The price of a road bike is $650; the price of a mountain bike is $700.
