Step-by-step explanation:
Answer:
slope = 1.25
Step-by-step explanation:
use the formula
m=rise/run or m=[tex]y_{2} - y_{1} / x_{2} - x_{1}[/tex]
-7-(-2)/(-3)-1

(3 points) A marketing research firm wishes to determine if the residents of Caldwell, Idaho, would be interested in a new downtown restaurant. The firm selects a simple random sample of 165 phone numbers from the Caldwell phone book and calls each household. Only 60 of those called are willing to participate in the survey, and 44 participants would support a new downtown restaurant. (a) The sample in this survey is A. all households in the Caldwell phone book. B. all residents of Caldwell. C. the 165 phone numbers chosen. D. the 60 households that participated in the study. E. None of the above. (b) The population of interest is A. all households in the Caldwell phone book. B. the 60 households that participated in the study. C. all residents of Caldwell. D. the 165 phone numbers chosen. E. None of the above. (c) The chance that all 165 phone numbers chosen are located in one particular neighborhood in Caldwell is A. reasonably large due to the ''cluster'' effect. B. 165 divided by the size of the population of Caldwell. C. exactly 0. Simple random sampling will spread out the locations of the phone numbers selected. D. the same as for any other set of 165 phone numbers. E. None of the above.
Answer:
Interest in a new downtown restaurant in Caldwell, Idaho:
(a) The sample in this survey is:
C. the 165 phone numbers chosen.
(b) The population of interest is:
C. all residents of Caldwell.
(c) The chance that all 165 phone numbers chosen are located in one particular neighborhood in Caldwell is:
E. None of the above.
Step-by-step explanation:
Population of interest = residents of Caldwell, Idaho
Sample of the population = 165
Number of willing participants/respondents = 60
Proportion of participants supporting a new downtown restaurant = 44/60 = 73%

The point A(6,-4) is reflected over the point (0,0) and its image is point B. What
are the coordinates of point B?
Answer:
B(-6,4)
Step-by-step explanation:
Basically, it's the same as reflecting it over the origin, so you transform the sign to its opposite and keep the points.
5,698+12,326 is even number are odd number
Answer: Even
Step-by-step explanation:
Look at the ones place of each number, which in this case is 8 and 6.
8 + 6 = 14, which is an even number. This makes the sum of both numbers also an even number.

Answer:
32.5 times 5
162.5 minutes total, or 2 hours and 42.5 minutes
Answer:
162.5 minutes in total.
Step-by-step explanation:
Since there are 5 people (Ethan AND his four friends) and each one of them drove for 32.5 minutes, you multiply 32.5 by 5. The answer should be 162.5, meaning Ethan and his four friends drove for 162.5 minutes total.
98 is 14% of what number?
Answer:
the answer is 13.72
Step-by-step explanation:
tell me if its right
Answer:
700
Step-by-step explanation:
We have, 14% × x = 98
or, 14
100 × x = 98
Multiplying both sides by 100 and dividing both sides by 14,
we have x = 98 ×
100
14
x = 700
If you are using a calculator, simply enter 98×100÷14, which will give you the answer.

She has a total of 26 coins. How many of each kind does she have?
Answer:
Diana has 14 dimes and 12 nickels
Step-by-step explanation:
Create a system of equations, where d is the number of dimes and n is the number of nickels:
d + n = 26
0.1d + 0.05n = 2
Solve by elimination by multiplying the top equation by -0.1:
-0.1d - 0.1n = -2.6
0.1d + 0.05n = 2
Add these together, then solve for n:
-0.05n = -0.6
n = 12
So, she has 12 nickels. To find the number of dimes, subtract 12 from 26, since there were 26 coins in total and we found that she had 12 nickels.
26 - 12
= 14
So, Diana has 14 dimes and 12 nickels

B/c they are similar triangles we can set the sides ratio's equal to each other again
7x + 6 / 56 = 78 /91
does it kind of makes sense why I'm able to set those two ratio's equal?
it's the tough part of these problems... understanding why that works
the rest is just algebra.. My calc II professor always told us our algebra sucks. :D he was funny,
anyway, use your mad algebra skilz on the above equation
7x + 6 = 56(78/91)
7x + 6 = 4368 / 91
7x + 6 = 48
7x = 48 - 6
7x = 42
x = 6

Given the polynomial f(x) = 3x ^ 3 - 4x ^ 2 - 3x - 1 what is the smallest positive integer a the Intermediate Value Theorem guarantees a zero exists between 0 and a? Enter an integer as your answer . For example , if you found a = 8 you would enter 8. Provide your answer below .
9514 1404 393
Answer:
2
Step-by-step explanation:
You need the smallest positive integer for which f(x) > 0.
f(1) = 3 -4 -3 -1 = -5
f(2) = ((3·2 -4)2 -3)2 -1 = (4 -3)2 -1 = 1
x = 2 is the smallest integer for which f(x) > 0.

Analyze the following budget, with an income of $600, to determine how much can be spent on food for the month
Question:
Analyze the following budget, with an income of $600, to determine how much can be spent on food for the month.
Cell Phone $65
Food $___
Entertainment $95
College Savings $200
Car Expenses - Gas, Insurance $160
Answer:
[tex]Food = \$80[/tex]
Step-by-step explanation:
Given
[tex]Income = \$600[/tex]
Required
How much should be spent on food
This is calculated as:
[tex]Income = Food + Other\ budgets[/tex]
Where:
[tex]Other\ budgets = Phone + Ent + College + Car, Gas[/tex]
[tex]Other\ budgets = \$65 + \$95 + \$200 + \$160[/tex]
[tex]Other\ budgets = \$520[/tex]
So, we have:
[tex]\$600 = Food + \$520[/tex]
[tex]Food = \$600 - \$520[/tex]
[tex]Food = \$80[/tex]
Answer:
C $80 can be spent on food.
