Add: (-15xz-4xy)+(20xy-9yz-16xz)
Answer:
=16xy−31xz−9yz
Step-by-step explanation:
The required simplified solution of the given expression is 16xy - 9yz -31xz.
Given that,
To determine the simplified solution of the given expression,
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
= (-15xz-4xy)+(20xy-9yz-16xz)
Adding the coefficients of the alike terms.
= 16xy - 9yz -31xz.
Thus, the required simplified solution of the given expression is 16xy - 9yz -31xz.

3. The math department needs to buy new textbooks and laptops for their
classrooms. The textbooks cost $116.00 each and the laptops cost
$439.00 each. If they need to purchase 30 textbooks and have $6500
to spend, what is the greatest number of laptops they can buy?
Write an inequality and solve.
Let they be x.
Cost of textbooks + laptops cant greater than total amount.
(cost of 1 textbooks * number of textbooks) + (cost of 1 laptop * number of laptops ≤ 6500
(30*116) + (x*439) ≤ 6500
3480 + 439x ≤ 6500
439x ≤ 3020
x ≤ 6.8(approx)
Last natural number is 6, says, they can buy 6 laptops at max.

Show all your work. Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. Kathy and her brother Clay recently ran in a local marathon. The distribution of finishing time for women was approximately normal with mean 259 minutes and standard deviation 32 minutes. The distribution of finishing time for men was approximately normal with mean 242 minutes and standard deviation 29 minutes. The finishing time for Clay was 289 minutes. Calculate and interpret the standardized score for Clayâs marathon time. Show your work.
Answer:
Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.
Step-by-step explanation:
In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.
Let us consider a random variable, X that follows a normal distribution, N (µ, σ²).
Then Z is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is,
[tex]Z=\frac{x-\mu}{\sigma}\sim N(0, 1)[/tex]
This, z-score is known as the standardized score.
It is provided that the distribution of finishing time for men (say, X) was approximately normal with mean µ = 242 minutes and standard deviation σ = 29 minutes.
The finishing time for Clay was x = 289 minutes.
Compute Clay's z-score as follows:
[tex]Z=\frac{x-\mu}{\sigma}[/tex]
[tex]=\frac{289-242}{29}\\\\=1.67857143\\\\\approx 1.68[/tex]
Thus, Clay's standardized score is 1.68.
That is, Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

Find the indicated conditional probability using the following two-way table
P(Take the bus|Junior)=[?]
round to the nearest hundredth.
Answer:
P(Take the bus|Junior)=0.57
Step-by-step explanation:
Conditional Probability
Is a measure of the probability of the occurrence of an event, given that another event has already occurred. If event B has occurred, then the probability that event A occurs is given by:
[tex]{\displaystyle P(A\mid B)={\frac {P(A\cap B)}{P(B)}}}[/tex]
Where [tex]P(A\cap B)[/tex] is the probability that both events occur and P(B) is the probability that B occurs.
The two-way table shows statistics of students and we are interested to find the probability that, given the student is a junior (let's call it event B), they also take the bus (Event A). Thus, the probability we need to calculate is:
[tex]\displaystyle P(A\mid B)={\frac {P(A\cap B)}{P(B)}}[/tex]
Checking on the table, we can see that both events occur when the row and the column of both events coincide, i.e. 20 students out of a total of 100 students in total. Thus:
[tex]\displaystyle P(A\cap B)=\frac {20}{100}=0.2[/tex]
The probability that a student is classified as Junior is
[tex]\displaystyle P(B)=\frac {35}{100}=0.35[/tex]
The conditional probability is:
[tex]\displaystyle P(A\mid B)=\frac {0.2}{0.35}=0.5714[/tex]
P(Take the bus|Junior)=0.57

The floor area of a rectangular room is 162 square feet. The width of the room is 9 feet. What is the length?
The length of the rectangular room will be;
⇒ 18 feet
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The area of a rectangular room = 162 square feet
The width of the room = 9 feet.
Now,
Since, we know that;
Area of Rectangle = Length x Width
Let The length of the room = y feet
Substitute all the given values, we get;
The area of a rectangular room = Length x Width
162 = y x 9
Divide by 9, we get;
y = 162 / 9
y = 18 feet.
Thus, The length of the rectangular room will be;
⇒ 18 feet
