Convert each of mixed number to an improper fraction
Answer:
Top, a through d:
A) 23/8
B) 29/6
C) 23/3
D) 16/5
Step-by-step explanation:
To make the proper fraction improper, first, multiply the whole number by the bottom number in the fraction, then add whatever number was on top of the fraction, so for A, multiply 2 (whole number) by 8 (number on the bottom of the fraction), then add 7 (number on top of the fraction)

Find the equation of a line perpendicular to y=-3x-1 that contains the point (-1,1). Write the equation in slope intercept form.
Answer:
y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
y = -3x - 1
1. Perpendicular line needs the opposite (reciprocal) of the slope.
reciprocal of -3 is -1/3, slope 1/3. y = 1/3x + b
2. Now find the b (y-intercept). 1 = 1/3(-1) + b
1 = -1/3 + b
+ 1/3 +1/3
1 1/3 = b
3. Answer y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]

25x + 15y=17
25x + 15y=305$
Neee answer ASAP
Answer:
1st. Problem
Let's solve for x.
25x+15y=17
Step 1: Add -15y to both sides.
25x+15y+−15y=17+−15y
25x=−15y+17
Step 2: Divide both sides by 25.
25x/25 = -15y+17/ 25
x equals...
x= -3/5 y + 17/25
2nd. Problem
Let's solve for x.
25x+15y=305
Step 1: Add -15y to both sides.
25x+15y+−15y=305+−15y
25x=−15y+305
Step 2: Divide both sides by 25.
25zx/25 = -15y305/25
x equals...
x = -3/5 y + 61/5
90 divided by 3 + ( 3 - 2 ) - 20.
Answer:
11
Step-by-step explanation:
first 3-2=1 the divide 90 by 3 then add the 1 the subtract that by 20 and you will get 11
The result of the expression 90 divided by 3 plus the quantity (3 minus 2) minus 20 is 11.
To evaluate the expression 90 divided by 3 + (3 - 2) - 20, we can follow the order of operations (also known as PEMDAS/BODMAS), which stands for Parentheses/Brackets, Order/Exponents, Division/Multiplication, and Addition/Subtraction:
First, let's simplify the expression within the parentheses:
3 - 2 = 1
Now we can substitute the simplified expression back into the main expression:
90 ÷ 3 + 1 - 20
Next, perform the division:
90 ÷ 3 = 30
Now we have:
30 + 1 - 20
Next, perform the addition:
30 + 1 = 31
Finally, perform the subtraction:
31 - 20 = 11
Therefore, the value of the expression 90 divided by 3 + (3 - 2) - 20 is 11.

How many square feet of outdoor carpet will
we need for this hole?
?
3 ft
Ift
2 ft
4 ft
2 ft
12 ft
Answer:
40 sq feet
Step-by-step explanation:
(im bad at explaining)
1 x 2 = 2 sq ft
3 x 2 = 6 sq ft
4 x 12 = 48 sq ft
2 sq ft + 6 + sq ft = 8 sq ft
48 - 8 = 40
The amount of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle) = 40 ft².
What is the Area of a Rectangle?Area of a rectangle = lenght × width.
The amount of square feet of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)
The amount of square feet of outdoor carpet needed = 12 × 4 - (3 × 2 + 2 × 1)

Exercise 1.6 introduces a study on the relationship between socio-economic class and unethical behavior. As part of this study 129 University of (California Berkeley undergraduates were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. They were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. After completing some unrelated tasks, participants reported the number of candies they had taken. It was found that those who were identified as upper-class took more candy than others.
A. Identify the population of interest and the sample in this study.
B. Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
(A) Population: UCB undergraduates
Sample: The selected 129 UCB undergraduates
(B) Yes, they can be generalized to the population
No, the findings of this single study cannot be used to establish causal relationships between socio-economic classes and unethical behaviors.
Step-by-step explanation:
STUDY: Relationship between socio-economic class and unethical behavior.
The bases for determining social class here are: money, education, and respected job.
RESULT: Those who identified as upper class took more candy than others.
(A) Identify the population of interest and the sample, in this study.
The population of interest in this study is UCB undergraduates.
The sample in this study is the 129 UCB undergraduates who were selected and who agreed to take part in the experiment. They were the participants who were divided into the two social classes before the experiment was conducted.
(B) The results of the study can be generalized to the population of UCB undergraduates since it's likely that the results would be same in another group of 129 UCB undergraduates.
The findings or results of the study cannot be used to establish causal relationships unless the study is conducted in more universities and majority of the results are same with this.

A second airline is conducting the same research about its planes, but this company is much bigger and has acquired data for 50 planes. Is a dot plot still beneficial to summarize the data?
Answer:
While it’s possible to create a dot plot using this data, plotting 50 points on a number line is cumbersome. The more data points there are, the more tedious it is to make a dot plot. For this case, it might be better to use a different visual representation.

For a normal distribution, what z-score value separates the lowest 25% of the scores from the rest of the distribution
Answer:
Z = -0.675.
Step-by-step explanation:
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 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.
What z-score value separates the lowest 25% of the scores from the rest of the distribution
This is Z which has a pvalue of 0.75, so Z = -0.675.

Find m\angle Am∠Am, angle, A.
Round to the nearest degree.
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA = [tex]\frac{-169+136}{120}[/tex]
cosA = -0.275
A = [tex]\text{cos}^{-1}(-0.275)[/tex]
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.
