Answer:
all students in the club
Step-by-step explanation:
Answer:
C. All students in each grade
Step-by-step explanation:
Answer choices A and B are the worst choices to represent all students in the school. D can also be crossed off because students in the social studies club would most likely have a biased answer. Surveying all students in each grade produces the most random, unbiased results, so C would be the best answer.
Hope this helps!
Maggie takes three electives: art, Spanish, and creative writing. She calculated the mean absolute deviation of the points she earned throughout the year in each class.
art: mean absolute deviation of 2.1
Spanish: mean absolute deviation of 0.8
creative writing: mean absolute deviation of 2.7
In which elective were her scores the most spread out?
art
creative writing
Spanish
Explanation:
MAD = mean absolute deviation
The larger the MAD, the more spread out the scores will be.
Therefore, Maggie has the most spread out scores in her creative writing class.

Determine which is the better buy.
9 straps for $10.25 or 30 straps for $66.00
Answer:
9 straps for $10.25
Step-by-step explanation:
Price rate
9 straps for $10.25 = 10.25/9 = $1.14 per strap30 straps for $66 = 66/30 = $2.20 per strapBetter buy
9 straps for $10.25Less cost per strapbetter buyAnswer:
9 straps
Step-by-step explanation:
If you're selling 30 straps for $66 then you get a 2.2 per each
But 9 straps for $10.25 will get 1.139
So, the value that's smaller which is 9 straps for $1.139 is a better buy

Data are collected about the amount of time, in minutes, each member of the lacrosse team spends practicing. How does a single outlier change the mean of the collected data?
A single outlier causes the value of the mean to move slightly toward the outlier.
A single outlier causes the value of the mean to move slightly away from the outlier.
A single outlier does not affect the value of the mean.
A single outlier doubles the value of the mean.

Kehlani is making a table. All but one of the boards that she uses to make the table are 15/16 inches thick. Kehlani’s last board is 1 1/8 inches thick. By how much does Kehlani need to reduce the thickness of her last board to match the other boards?
Answer:
3/16 of an inch
Step-by-step explanation:
1 1/8 of an inch is 1 2/16, which is also 18/16. 18/16-15/16 = 3/16.

a cast member is selling balloons on main street. he has 4 princess balloon, 5 blue mickey balloons and 1 red mickey balloon. he sells 1 balloon and then another (no replacing). find the probability of selling one blue balloon followed by another blue balloon.
Answer:
hee-hee!
Step-by-step explanation:
We first have to find how many possible outcomes there are.
We find that out by seeing how many types of balloons are in total.
4 + 5 + 1 = 10
There are 10 possible outcomes.
We then see how many favorable outcomes there are.
There are 5 blue mickey balloons.
That means 5/10 or 1/2.
Then we subtract 1/10 from 5/10.
5/10 - 1/10 = 4/9
We lower the denominator by 1 because the total possible outcomes are also lowered by one.
The probability of the cast member selling another blue balloon after selling the first one is 4/9.
hope this helps :)

A store sells grass seed in small bags and large bags. The small bags have 7 pounds of seed for $27.93 and the large bags have 20 pounds of seed for $66.98. Which type of bag is the better buy? Explain your reasoning.
Answer:
The 20 pound bag is a better by for only $66.98
Step-by-step explanation:
The large bag is better because the small bag is $27.93 for 7 pounds 7x3=21,so 3x27.93=83.79 is $16.81 more than the cost for the large bag

Can someone help me with this math equation? Can you explain how to work it out also?
Answer: 50
Explanation:What we know:The numerator is 6The denominator is equal to (3*5)^(-2)In fraction-style equations, the numerators are divided by denominatorsNegative exponents are equal to (base)^|power|, and then reversing the products place in the fraction
How to solve:
By utilizing our knowledge of the PEMDAS solving method, negative powers, and fraction-style equations, this problem can be solved with a simple step-by-step procedure
Process:ExponentSet up equation 6 / [3 * 5^(-2)]
Rewrite power 6 / [3 * (5 * 5)]
Simplify power 6 / [3 * (25)]
Invert power 6(25) / 3
SimplifyingSet up equation 6(25) / 3
Simplify 150 / 3
Simplify (using common denominator) 50 / 1
Rewrite in simplest form =50

Slope Formula:[tex]\bold{\displaystyle\frac{y_2-y_1}{x_2-x_1}}[/tex]
Where[tex]\bold{y_2}[/tex] is the y-coordinate of the second point
[tex]\bold{y_1}[/tex] is the y-coordinate of the first point
[tex]\bold{x_2}[/tex] is the x-coordinate of the second point
[tex]\bold{x_1}[/tex] is the x-coordinate of the first point
Check the First example:
[tex]\bf{y_2}[/tex] = 6
[tex]\bf{y_1}[/tex]= -2
[tex]\bf{x_2}[/tex]=3
[tex]\bf{x_1}[/tex] = -9
Plug in the Values[tex]\bf{\displaystyle\frac{6-(-2)}{3-(-9)} }[/tex]
6-(-2) is the same as 6+2; same with 3-(-9)
[tex]\bf{\displaystyle\frac{6+2}{3+9}}[/tex]
Simplify:
[tex]\bf{\displaystyle\frac{8}{12}}[/tex]
Is the slope negative? Nope!
How about Option B?
[tex]\bf{\displaystyle\frac{7-9}{5-6}}[/tex]
[tex]\bf{\displaystyle\frac{-2}{-1}}[/tex]
Right now it seems like the slope's negative, huh? Well, wait for it...
[tex]\bf{2}[/tex]
Kaboom!
Please remember that
[tex]\bigstar^\circ[/tex] A negative number multiplied/divided by a negative number equals... a positive! :-)
We have 2 options left: C & D.
[tex]\displaystyle\frac{-8-1}{8-(-8)}[/tex]
[tex]\displaystyle\frac{-8-1}{8+8}}[/tex]
[tex]\displaystyle\frac{-9}{16}}[/tex]
We did it! The slope's actually negative :)
How about Option D (just to make sure the third option is right)
-9-(-8)/-1-2
-9+8/-3
-1/-3
Again we have a negative over a negative.
Therefore, the correct option is[tex]\boxed{\boxed{\bold{Option~C}}}[/tex]
Hope everything is clear.
