A teacher said that 68% would be the
lowest passing test score. Kanisha got
19 out of 28 problems correct. What
was her test score? Was it a passing
score?
A percentage is out of 100%.
19 (questions right) / 28 (total) = 0.67857142857
Round to the tenth, 67.9.
67.9%, not a passing score.Answer:
Kanisha's test score is approximately 67.8571 percent.
Step-by-step explanation:
19/28 is about 67.8571, just under the 68 percent passing score. However, if her test score is rounded up, it will exactly meet the lowest passing score.

Which expression shows the first step in applying the distributive property to
6(8-3)?
A.
6.8 +6
B.
1 2 3
(6 - 8) (6-1
-
o D. 6.8-6. 1 / 3
C.
6
- 6-8
Answer:
Answer: Option D
Answer: Option DStep-by-step explanation:
• In distributive property, we multiply the factor to each term in the bracket. So that the reverse is true.
Take an example;
[tex] \dashrightarrow \: { \rm{x(y + z)}}[/tex]
• To apply distributive property, mulyiply both y and z by x following the addition operation.
summary:
[tex] \dashrightarrow \: { \rm{xy + xz}}[/tex]
→ The expression above is the expansion using distributive property.
• Back to the question, we are given a factorised expression;
[tex]{ \rm{6(8 - \frac{1}{3} )}} \\ [/tex]
• To apply the distributive property, multiply 8 and ⅓ by 6:
[tex] \dashrightarrow \: { \boxed{ \boxed{ \rm{ \: (6 \: • \: 8 - 6 \: • \: \frac{1}{3}) }}}} \\ [/tex]

Step-by-step explanation:
63+36+X = 180 (interior angles of a triangle equal 180)
X = 180-99
X= 81
X+Z= 180(angles on a straight line adds up to 180)
81+y= 180
Z=180-81
Z =99
13+Z+Y=180
13+99+Y=180
Y=180-112
Y=68

Five years ago, Enormous State University's campus publication, The Campus Inquirer, ran a total of 11 exposés dealing with alleged recruiting violations by the football team and with theft by the student treasurer of the film society. Each exposé dealing with recruiting violations resulted in a $3 million libel suit, and the treasurer of the film society sued the paper for $2 million as a result of each exposé about his alleged theft. Unfortunately for The Campus Inquirer, all the lawsuits were successful, and the paper wound up being ordered to pay $29 million in damages. (It closed down shortly thereafter.) How many of each type of exposé did the paper run? exposés on the football team exposés on the film society treasurer
Graph 4x +3x=11 and x=y+1 as 2 separate lines that intersect.
Answer:
Step-by-step explanation:
So first of all, you can rearrange your equations:
4x + 7x = 11 can be rearranged and simplified to x = 11/7
x = y + 1 can be rearranged to y = x - 1
Then you can graph them like normal by plugging in points. It should look like the following picture

In how many ways can 8 diplomats be seated at a round table?
A)40,320
B)5,040
C)720
Answer:
5040Step-by-step explanation:
Now, imagine a specific arrangement. Now, have everyone get up and move one seat to their right. That arrangement was counted separately from the first one in the 8! but it’s really the same since if each person looks to their left and their right, they’re sitting next to the same person. There are 8 such “identical rotations” for each possible seating arrangement so the total number of seatings is 8! / 8 = 7! = 5040.HOPE IT HELPS

x= -6/5 x= -3 or 3
x(x-1)-x^2+2x=5 :))))))
Answer:
[tex]x(x - 1) - {x}^{2} + 2x = 5 \\ {x}^{2} - x - {x}^{2} + 2x = 5 \\ \therefore \: x \: = 5[/tex]
Answer:
x=5
Step-by-step explanation:
[tex]x(x-1)-x^2+2x=5[/tex]
expand by using distributive property
[tex]x^2-x-x^2+2x=5[/tex]
simplify
x=5
check work by substituting 5 into the original equation and simplify
use PEMDAS
[tex]5(5-1)-5^2+2(5)=5[/tex]
[tex]5(4)-25+10=5[/tex]
add and subtract (left to right)
20-25+10=5
5=5
The equation is true, thus x=5
1. What is the probability that a randomly selected student from your group is a 9th grader?
2. What is the probability that a randomly selected student from your group prefers comedy?
3. what is the probability that a randomly selected student does NOT prefer action?
4. What is the probability that a student prefers comedy, given that the student is in 10th grade?
5. What is the probability that a student prefers comedy, given that the student is in 12th grade?
6. what is the probability that a student does not prefer action, given that the student is in the 9th grade?
7. Compare questions 4, 6, and 7. If you are given a students grade level, does that change the probability that he or she will prefer comedy?
Total students = 16
1. Total 9th graders = 3
Probability of being 9th grader = 3/16
2. Total that like comedy = 6
Probability = 6/16 = 3/8
3. 3 like action so 16-3 = 13 do not.
Probability = 13/16
4. 1 10th grader likes comedy out of 5 10th graders
Probability = 1/5
5. 0 out of 3 12th graders like comedy.
Probability = 0
6. 0 like action out of 3
Probability = 3/3 = 1
7. Yes the probabilities are different.
Answer:
1. P) 3/16
2. P) 6/16 or 3/8
3. P) 13/16 as 1- 3/16 = 13/16
4. P) 2/3
5. P) 1/5
6. P) 3/3 = 1
7. Yes as such grades do not represent the no of people shown on the table

Answer:
Step-by-step explanation:
We have to do an expression doing A - B
So we have to subtract A-B, let us see what we can do.
Distance between AB
= A - B
B = 0.5
A = -2.5
= 0.5 - (-2.5)
= 0.5 + 2.5
= 3
The additional inverse of the number a is the number that, when added to a , yields zero.
negation of each other
