=3+(18-6)+20÷4
=3+12+20÷4
=3+12+5
=20
use BODMAS rule (Bracket of Division, Multiplication, Addition, and Subtraction)
Answer:
20 is the answer.
Step-by-step explanation:
By using BODMAS,
→ 3 + (18 - 6) + 20 ÷ 4
→ 3 + 12 + 20 ÷ 4
→ 3 + 12 + 5 = 20

Half of Isiah’s money is equal to ⅔ of Bob’s money. Isiah has $15 more than Bob. How much money do they have altogether?
The amount of money they have altogether is $105.
What is the system of equations that represent the question?i - b = $15 equation 1
1/2i = 2/3b
3i = 4b
i = 4b/3 equation 2
Where:
i = amount of money Isiah has
b = amount of money Bob has
How much money does Bob have?Substitute for the value of i in equation 1
4b/3 - b = $15
1/3b = $15
Multiply both sides of the equation by 3
b = $45
How much money does Isiah have?
Substitute for $45 in equation 1
i - $45 = $15
Add $45 to both sides of the equation
i = $45 + $15
i = $60
How much do they both have?
$60 + $45 = $105

A cylindrical fuel tank is 1.25 meters high and has
a radius of 0.60 meter. If the tank can only be
filled to an 85% capacity to allow for expansion
of the fuel, what is the maximum volume of fuel?
Answer:
The maximum volume of the fuel is:
[tex]V_{fuel}=1.20 \: m^{3}[/tex]
Step-by-step explanation:
The volume of the cylinder is given by:
[tex]V=\pi r^{2}h[/tex]
[tex]V=\pi (0.6^{2})(1.25)[/tex]
[tex]V=1.41 \: m^{3}[/tex]
If the tank can be filled to 85% of its capacity, the maximum volume of the fuel will be:
[tex]V_{fuel}=1.41*(\frac{85}{100})[/tex]
[tex]V_{fuel}=1.20 \: m^{3}[/tex]

Below is a regression analysis of the number of burglaries in 2006 (response variable) on the student enrollment (explanatory variable) for 17 randomly-selected four-year public universities in the United States. Assume that the conditions for regression inference have been satistied.
Predictor Coef SE Coef T P
Constant 4.43 10.41 0.43 0.677
Enrollment 0.0018751 0.0005724 3.28 0.005
S= 22.5012 R-Sq= 41.7% R-Sq (adj ) =37.8%
Which of the following is an appropriate interpretation of the number 22.5012?
(a) The standard deviation of the response variable "student enrollment" is 22.5012.
(b) The standard deviation of th explanatory variable "number of burglaries" is 22.5012. )
(c) The typical distance between observed values for student enrollment and values for enrollment predicted by the regression equation is about 22.5012.
(d) The typical distance between observed values for number of burglaries and values for number of burglaries predicted by the regression equation is about 22.5012.
(e) The sum of the squared deviations between the observed number of burglaries and the number of burglaries predicted by the regression equation is about 22.5012
Answer:
d. The typical distance between observed values for number of burglaries and values for number of burglaries predicted by the regression equation is about 22.5012.
Step-by-step explanation:
In a regression output, the S which is the standard error of the regression, gives us the absolute measure of the average distance from which the observed data point falls from the line of regression. S is in the unit of the response variable or the dependent variable. The response variable is the number of burglaries in 2006. Based on this explanation, option d is the best and right answer for this question.

Use a statistics calculator to find the area, in decimal form, rounded to four places after the decimal, under the (standard) Normal histogram and... (a) ...to the left of 1.8. (b) ...to the right of 2.4. (c) ...between 1.8 and 2.4.
Answer:
a) 0.9641.
b) 0.0082
c) 0.0277
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
(a) ...to the left of 1.8.
p-value of Z = 1.8, which, looking at the z-table, is of 0.9641.
(b) ...to the right of 2.4.
1 subtracted by the p-value of Z = 2.4.
Looking at the z-table, Z = 2.4 has a p-value of 0.9918.
1 - 0.9918 = 0.0082, which is the answer.
(c) ...between 1.8 and 2.4.
p-value of Z = 2.4 subtracted by the p-value of Z = 1.8.
From itens a and b, we have both. So
0.9918 - 0.9641 = 0.0277

The average of any two consecutive even numbers in an even number. Find a counterexample.
Answer:
2 and 4
Step-by-step explanation:
2+4 = 6
6/2 = 3
average is sum of number divided by how many numbers there are.
A counterexample to the above rule of the average of two consecutive even numbers being even are 8 and 10.
A counterexample is one that disproves a logic.
The consecutive even numbers of 8 and 10 will give an average of:
= Sum of even numbers / 2
= (8 + 10) / 2
= 18 / 2
= 9
9 is not an even number so we can conclude that 8 and 10 are counterexamples to the above rule.
