Answer:
12
Step-by-step explanation:
So since the total was 26.95 subtract the base cost of the mug which is 8.95
26.95-8.95=18.00
Then since each refill is 1.50 divide by 1.50
18/1.50=12

Consider each expression. if x = -2, is the value of the expression
a positive number? Select Yes or No.
A. -2(x - 2)
Yes
No
B. –3x(5 – 4x)
Yes
No
C. x + 6x
O Yes O No
Answer:
Yes
Yes
No
Step-by-step explanation:
Given value x = -2;
Problem, is the expression a positive number ?
A. -2(x - 2)
if x = -2
-2(-2 - 2)
= -2 (-4)
= 8
Yes
B. -3x(5 - 4x)
if x = -2
-3 x -2(5 - 4(-2))
= 6 (5 + 8)
= 6 x 13
= 78
Yes
C. x + 6x
if x = -2
-2 + 6(-2)
= -2 - 12
= - 14

g Problem 7. (10 points) A random sample of 100 Cooper County residents showed that 18 are college graduates and a second random sample of 50 Boone County residents showed that 28 are college graduates. Round your final answer to each part to three decimal places, but do not round during intermediate steps. The relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is
Answer:
The relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is 3.11.
Step-by-step explanation:
Denote the events as follows:
C = Cooper County resident
B = Boone County resident
G = graduate
NG = non-graduate
The information provided is summarized as follows:
G NG Total
C 18 82 100
B 28 22 50
Total 46 104 150
Compute the relative risk of being a college graduate for Boone County residents as compared to Cooper County residents as follows:
[tex]\text{Relative Risk}=\frac{\text{Graduates in Boone County}}{\text{Graduates in Cooper County}}[/tex]
[tex]=\frac{28/50}{18/100}\\\\=\frac{28}{50}\times \frac{100}{18}\\\\=3.11111\\\\\approx 3.11[/tex]
Thus, the relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is 3.11.
The relative risk of remaining a college graduate for Boon County residents in comparison to Cooper County residents would be 0.500
Relative risk:Relative risk is used in the statistical analysis of the data of ecological, cohort, medical, and intervention studies, to estimate the strength of the association between exposures (treatments or risk factors) and outcomes. Mathematically, it is the incidence rate of the outcome in the exposed group.
The relative risk is calculated by dividing the probability of an event for group 1 divided by the probability of an event occurring for group 2.

Answer:
10
Step-by-step explanation:
Given expression:
20 - [tex]\frac{15 + 3(5)^{2} }{5^{2} - 4^{2} }[/tex]
To solve this problem, we use the order of operation:
P - Parentheses
E - exponents

A - Addition
S - Subtraction
Now solve the parentheses first;

= 20 - [tex]\frac{15 + 75}{5^{2} - 4^{2} }[/tex]
Now solve the exponents:
= 20 - [tex]\frac{15 + 75}{25 - 16}[/tex]
Now solve the division:
= 20 - [tex]\frac{90}{9}[/tex]
= 20 - 10

The science teacher gives daily homework. For a random sample of days throughout the year, the median number of problems is 5 and the IQR is 2. The Spanish teacher also gives daily homework. For a random sample of days throughout the year, the median number of problems is 10 and the IQR is 1. If you estimate the median number of science homework problems to be 5 and the median number of Spanish problems to be 10, which is more likely to be accurate? Explain your reasoning.
Answer:
SCIENCE SEEMS MORE ACCURATE
Step-by-step explanation:
The interquartile range (IQR) = difference between the upper and lower quartile (Q3 - Q1)
The median can be estimated as :
(Q3 - IQR/2) or (Q1 + IQR/2).
FOR SCIENCE:
MEDIAN NUMBER = 5
IQR = 2
IQR = Q3 - Q1
Q3 = median + IQR/ 2 = 5 + 2/2 = 6
Q1 = median - IQR/2 = 5 - 2/2 = 4
FOR SPANISH:
MEDIAN = 10
IQR = 1
IQR = Q3 - Q1
Q3 = median + IQR/ 2 = 10 + 1/2 = 10.5
Q1 = median - IQR/2 = 10 - 1/2 = 9.5
Science has a lower median score and an interquartile range which is reasonable wider than Spanish with a larger median value (but a very narrow interquartile range).

Simon score 4x10^2 points in a game. Joe scored 2x10^3 points in the same game. whose score is higher? how much higher?
Answer:
Joe scored higher by 1600
Step-by-step explanation:
Given
[tex]Simon = 4 * 10^2[/tex]
[tex]Joe = 2 * 10^3[/tex]
Solving (a): Which is higher?
First, we need to convert both numbers to whole numbers
[tex]Simon = 4 * 100[/tex]
[tex]Simon = 400[/tex]
[tex]Joe = 2 * 10^3[/tex]
[tex]Joe = 2 * 1000[/tex]
[tex]Joe = 2000[/tex]
2000 is greater than 400;
Hence, Joe score higher
Solving (b): By how much?
We simply calculate the difference
[tex]Difference = Joe - Simon[/tex]
[tex]Difference = 2000 - 400[/tex]
[tex]Difference = 1600[/tex]

Simon bought three plants at a nursery for 17.94 how hutch money would it cost for Simon to go back to the store and buy two more plants. Please help me !
Answer:
11-96
Step-by-step explanation:
The money required for Simon to buy two more plants is 11.96
What is Average?
The average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Given data ,
Number of plants Simon bought = 3 plants
Total amount of plants = 17.94
Amount for one plant = Total amount of plants / Number of plants bought
So , Amount for one plant = 17.94 / 3
= 5.98
Therefore , Amount of cost for Simon to buy two more plants = Amount of one plant x 5.98
= 5.98 x 2
= 11.96
Hence , The money required for Simon to buy two more plants is 11.96

The probability that the tourist visits atleast one of the two places is 0.90
Probability of cave visit, P(C) = 0.70
Probability of park visit = P(N) = 0.6
Probability of both = P(B) = 0.40
The probability of visiting atleast one of the two places can be defined thus :
