On a unit test in a statistics class, the teacher determines that the mean test grade was 77.5 with a standard deviation of 5.2. One test grade has a z-score of 2.4. Which of the following statements gives the best interpretation of this z-
score?
A. This student's test grade was higher than 2.4% of the other students' test grades.
B. This student's test grade was 2.4 standard deviations above the mean test grade.
C. This student's test grade was 2.4 standard deviations below the mean test grade.
D. The student's test grade was lower than 2.4% of the other students' test grades.
Answer: B. This student's test grade was 2.4 standard deviations above the mean test grade.
====================================================
Explanation:
The z score tells us how far away the raw score is from the mean. This distance is in terms of standard deviations.
z = 1 means we're 1 standard deviation above the meanz = 2 means we're 2 standard deviations above the meanand so on.
Negative z scores indicate the raw score is below the mean.
z = -1 means we're 1 standard deviation below the meanz = -2 means we're 2 standard deviations below the meanand so on. So that's why z = 2.4 indicates the students test grade was 2.4 standard deviations above the mean.

Answer:
x = 2
y = 2
Step-by-step explanation:
x + 8y = 18
-5x + 3y = -4
multiply entire first equation by 5 to get
5x + 40y = 90
add second equation
5x + 40y = 90
+(-5x + 3y = -4)
----------------------------
43y = 86
y = 2
plug it in now
x + 8(2) = 18
x = 2
-5x + 3(2) = -4
x = 2

On Monday, the theater club sells 14 tickets for the school play. On Tuesday, they sell 10 tickets. On those two days, they sell 30% of the total number of tickets. What is the total number of tickets?
Answer:
31 ticketsStep-by-step explanation:
Step one:
number of tickets sold
monday=14
tuesday=10
the number of tickets sold for Monday and Tuesday combined is
14+10= 24
step two:
we want to find how many tickets make 30%
so 30/100*24
0.3*24
=7.2 tickets,
Approximately 7 ticket
Therefore the total ticket is
14+10+7
=31 tickets
When a number is decreased by 3 and the result is doubled, the answer is equal to the original number. Find the number

6-3=3
3+3=6
The value of the number that it is decreased by 3 and the result is doubled will be 6.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Suppose that number is x.
x is decreased by 3 = x - 3
The results is doubled = 2(x - 3) = x
2x - 6 = x
2x - x = 6
x = 6
Hence "When a number is reduced by three and the outcome is doubled, its value becomes six".

Adele and Monte are discussing graphs with negative correlation. Adele claims that only graph B has negative correlation. Monte claims that both scatterplots have a negative correlation. Graph A Graph B On a graph titled Graph A, points are connected to form a curved line. On a graph titled Graph B, points are connected to form a line with negative slope. Which statement it true regarding their claims? Adele is correct because only lines may have a negative slope. Adele is correct because the y values increase as the x values decrease in graph A, so it shows a positive correlation. Monte is correct because both graphs show a strong correlation. Monte is correct because in both scatterplots, the y values decrease as the x values increase so both have a negative correlation.

Step-by-step explanation:
Can someone help me with those questions? (Try your best plzz)
Answer:
Step-by-step explanation:
1. 34 animals because of 34 heads.
94 legs: 4 per cow, 2 per chicken
x= # of cows
y= # of chickens
so x+y=34
4x+2y=94
Multiply the first equation by -2 is -2x-2y=-68 and add it to the first equation.
which is 2x=26. so x=13. Since x+y=34, 13+y=34.
Therefore, y=21
13 cows and 21 chickens.
2. lets say
pizza=y
soda=x
6x+x=14 combine like terms
7x=14 divide both sides by 7
x=2
So a soda is $2.
6*2=12. So the pizza is $12.
12+2=14. So it's correct.
3.
# of DVDS=x
# of Bluray= y
11x+17y=95
x+y=7
dvds-4
blu-ray-3 (I just did trial and error, but it's correct)
4.
# of 2-points= x
# of 3-points= y
2x+3y=18
2(6)+3(2)=18
so 6 two-point shots and 2 three-point shots.
5.
12 coins are quarters and 14 are dollar coins.
let q stand for the number of quarters
and 26 coins in total
26-q= dollar coins
x=dollar coins too
so its 1x+.25(26-x)=17
1x+6.5-0.25x=17
.75x+6.5=17
.75x=10.5
x=14
17-14=3
3*4= 12 since 4 quarters in a dollar.
