Answers
Answer:
y = 4x + 3
Step-by-step explanation:
Step 1: Write the general equation
y = mx + b
Step 2: Identify b, the Y intercept (x = 0)
b is the value of y when x = 0.
From the graph, when x = 0, y = 3.
Therefore, b = 3
Step 3: The second point from graph (x, y):
P = (1, 7)
Step 4: Define m as ratio of rise / run:
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Step 5: Put coordinates into ratio:
Using the two coordinates, (0, 3) and (1, 7), we would have,
[tex] m = \frac{7 - 3}{1 - 0} [/tex]
Step 6: Perform subtraction to get slope:
[tex] m = \frac{4}{1} [/tex]
m = 4
Step 7: Substitute values into y = mx + b:
Thus, plug in the values of m and b into the slope-intercept equation.
b = 3, m = 4, therefore:
y = (4)x + (3)
Step 8: Write answer:
y = 4x + 3

A trade school would like to measure the long-term success of their graduates after they leave the school. The school
emails a survey requesting information from graduates about their work experience. One question asks graduates to
share their annual salar), and the results of the question will be shared in a brochure for incoming students. Is it likely
that the survey results will provide an accurate estimate of mean annual salary for all of the school's graduates?
Answers
Answer:
Yes
Step-by-step explanation:
The survey would definitely provide an accurate estimate for that. This is because while the participants are undertaking the survey, the fact that it was their school of study that gave them the survey, makes it less likely for them to lie about their income. And thus, after collecting the response from the participants, surely, they would have the income earnings from their former students and be able to calculate the mean income of them all

If labor costs were $3,000,000 last year and $2,700,000 this year, what percentage decrease was achieved?
Answers
Answer:10%
Step-by-step explanation:
The percentage decrease achieved would be 10 % when labor costs were $3,000,000 last year and $2,700,000 this year.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Saima obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.
The labor costs were $3,000,000 last year and $2,700,000 this year which is given in the question.
We have to determine the percentage decrease that was achieved.
As per the given information, the required evaluation would be as:
⇒ ($3,000,000 - $2,700,000)/3,000,000 × 100
⇒ 3,000,00/3,000,000 × 100
⇒ 0.10 × 100
⇒ 10 %
Therefore, the percentage decrease achieved would be 10 %.

Equation Solving
Given the formula:
[tex]\displaystyle A=\frac{1}{2}h(b_1+b_2)[/tex]
It's required to solve it for b2.
First, we eliminate denominators by multiplying by 2:

Divide by h:
[tex]\displaystyle \frac{2A}{h}=b_1+b_2[/tex]

C. The median is 5, and the interquartile range is 10
D. The median is 5, and the interquartile range is 5
Answers
Answer:
Letter B is the correct answer. Median is 4 and IQR is 5.
Step-by-step explanation:
The median is 4 and the interquartile range is 6. The correct option is B.
What is an interquartile range?The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.
The median is the middlemost value of the numbers arranged in ascending orders. If the number of the data is an odd number so the median will be a middle number if the number of the data is even then the median is the mean of the middle two numbers.
The data is given below:-
0,0,0,1,1,3,3,3,4,4,4,6,6,7,7,7,8,8,9,10
Median = (4 + 4) / 2 = 4
The interquartile range is calculated as:-
0,0,0,1,1,3,3,3,4, | 4,4 |, 6,6,7,7,7,8,8,9,10
Lower range upper range
IQR = 7 - 1 = 6
Therefore, the median is 4 and the interquartile range is 6. The correct option is B.

A piggy bank contains dimes and nickels that are worth a total of $42.45. If there are 197 nickels, how
many dimes are there?
Answers
Answer:
326 dimes.
Step-by-step explanation:
total value = 197 * value of one nickel
total value = 197 * 0.05
total value = 9.85
Value of dimes = 42.45 - 9.85
Value of dimes = 32.60
1 dollar contains 10 dimes
32.60 dollars contain x dimes
1/32.60 = 10/x Cross multiply
x = 32.60 * 10
x = 326 Dimes
Answer: 326 dimes
Step-by-step explanation:
q + 0.05(197) = 42.45
q + 9.85 = 42.45
q = 42.45 - 9.85
q = $32.6
32.6 / 0.10 = 326
