Mr. Kazadi said that in his 2nd-period class, 23 out of 25 students passed the test. What percent of the students passed the test?
%
Answers
[tex]\text{Hello there!}[/tex]
To find a percentage, you will need to divide both numbers by each other. In this case, it would look similar to this:
[tex]\text{23 / 25 = ???}[/tex]
Once you divide the two numbers, you should end up with a result of [tex]0.92[/tex]
Now, we are going to move the decimal two spaces to the right to end up with the result:
[tex]\text{092.}[/tex]
Now, we are going to remove the [tex]0[/tex] as it is no longer required. Next, add a percentage symbol to the last number, and remove the decimal from the number.
Now, you should end up with something like this:
[tex]92\%[/tex]
[tex]\fbox{So your final answer is going to be 92\%}[/tex]
[tex]\rule{299}{1.5}[/tex]
A professor grades a set of exams and then computes the quartiles:
Q0 = 60. Q1 = 70. Q2 = 80 Q3 = 87. Q4 = 95
If the professor curves every grade up by 10 points, then how will Q2 be affected by the curve?
I. It will increase by 10 points
ii. It will be 10 points higher than the median for the noncurved data
III It will be halfway between Q1 and Q3 for the curved data
a. I only
b. II and III
c. I, II and III
d. I and II
e. I and III
Answers
Answer:
Answer is c. I, II and II
Step-by-step explanation:
Solution:
Answer is c. I, II and II
It will be increase by 10 points and it will be 10 points higher than the median for the noncurved data. and it will be halfway between Q1 and Q3 for the curved data.
Median for noncurved data = Q2 = 80
Median for curved data = 90
It will increase by 10 points = 90
It will be 10 points higher than the noncurved data = 90-80 = 10 points
if the set contains 20 values then, noncurved data will be:
60 _ _ _ _ 70 _ _ _ _ 80 _ _ _ _ 87 _ _ _ _ 95
Curved data will be: (all grades increased by 10 points)
70 _ _ _ _ 80 _ _ _ _ 90 _ _ _ _ 97 _ _ _ _ 105
Here, we can see median = Q2 = 90, exactly, halfway between Q1 =80 and Q3 = 97
Hence, C is the right answer
identify which of the angles are complementary supplementary or neither
Answers
A complementary angle is an angle that measures
90 degrees and they are also classified as right angles.
A supplementary angle is an angle that measures 180 degrees.
(i) Since the sum of the measures is 90 degrees, they are complementary.
(ii) Since the sum of their measures is 180 degrees, they are supplementary.
(iii) Since the sum of their measures is not 90 or 180, they are neither.
(iv) Since the sum of their measures is 180 degrees, they are supplementary.
(v) Since the sum of their measures is 180 degrees, they are supplementary.
(vi) Since the sum of their measures is 90, we have complementary.

Write an equation for the number of dollars, d, you spend on b boxes.
Yesterday, you purchased 2 boxes. Today you purchase 5 boxes.
Place points on the graph to show your purchases yesterday and today.
Answers
Answer:
d = 6b
Step-by-step explanation:
The number of dollars will be 6 times the number of boxes you buy.
When you buy 2 boxes, it costs 6 * 2 = $12, so one point should go at (2, 12).
When you buy 5 boxes, it costs 6 * 5 = $30, so one point should go at (5, 30)

what is the solution to the equation 5/8(4x-16)=20
Answers
The solution of the expression will be;
⇒ x = 14
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 5/8 (4x - 16) = 20
Now,
Since, The expression is,
⇒ 5/8 (4x - 16) = 20
Solve for x as;
⇒ 5 (4x - 16) = 20 × 8
⇒ 4x - 16 = 20 × 8/5
⇒ 4x - 16 = 40
⇒ 4x = 40 + 16
⇒ 4x = 56
⇒ x = 14
Thus, The solution of the expression will be;
⇒ x = 14

From the attachment, we have:
[tex]BC = x + 4[/tex]
[tex]BD = 2x - 7[/tex]
[tex]GE = 51[/tex]
[tex]GF = 57[/tex]
Because both triangles are similar, we use the following equivalent ratios:
[tex]BC : BD = GE : GF[/tex]
Substitute values for each parameter
[tex]x + 4 : 2x- 7 = 51 : 57[/tex]
Convert to fractions
[tex]\frac{x + 4}{2x- 7} = \frac{51 }{ 57}[/tex]
