of the students got problem 10 wrong on Friday's math test.
Which best describes the probability of the rolling a 7 on a number cube that is numbered from 1 through 6
Answer:
[tex]\huge\boxed{\text{Impossible}}[/tex]
Step-by-step explanation:
To find the probability of something happening, we find all the outcomes that can happen, find all the outcomes in which our criteria is met, and set that up as a fraction, where it's criteria met/total possible outcomes.
When we roll a 6-sided die, we will have 6 possible outcomes that we can roll.
1, 2, 3, 4, 5, and 6.
We can not roll anything except these 6! Since a die only has 6 sides, numbered 1-6, we will only roll these numbers.
7 is not in this list! It is impossible to roll a 7 on a die that only has 6 sides. Since 7 isn't even possible, it would be impossible to get a 7 on a 6-sided die.
Hope this helped!

Answer:
Conner's work is correct
Step-by-step explanation:
In exponent multiplication, if base are same, add the exponents.
[tex]a^{m}*a^{n} =a^{m+n}[/tex]
For example,
5² * 5³
5² = 5 * 5
5³ = 5* 5 * 5
5² * 5³ = 5 * 5 * 5 * 5 * 5 = 5⁵ = 5⁽²⁺³⁾
Answe
Conner is correct .Step-by-step explanation:
Because as he used the laws of indices to answer the questionPart A: Xavier needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the correctly written inequality to represent the number of cans, c, that Xavier must still collect (before solving)
A 64 + c ≥ 120
B 64 + c < 120
C c - 120 ≤ 64
Answer:
A
Step-by-step explanation:
He needs to collect at least 120 so if c is what he must still collect
64 +c must be greater than or equal to 120

Jack had four Snicker bars and 8 Mars bars. He randomly chose a piece of candy, ate it, then chose another. What is the probability that both candy bars were Snickers?
1/11
1/3
1/2
1/13
Answer:
1/3
If 4 are snickers and 8 are mars bars then 4/12 would be snickers so when you simplify 4/12 you get 1/3.

Answer:
5) r=40 gals/min
6) r= 125 mm/hr
7) $2600
8) d = 36 in
9) h= 1176 m
Step-by-step explanation:
5) r=v/r
r= 15,600 gals ÷ 390 mins
r= 40 gals/min
6) r=v/t
r= 1000mm ÷ 8 hrs
r= 125 mm/hr
7) $4500 - $1900 = $2600
8) C = Pi x d
c/Pi =d
113 in/3.14 = d
d = 36 in
9) Formula for h
h = 2 x a/b
h = 2 (84m2/12m)
h = 2 (7056/12)
h = 2(588)
h = 1176 m

Answer:
Slope is 2/3
Y-intercept is (0, 0)
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
y = 2/3x
Answer:
Slope is 2/3
y intercept is 0
Step-by-step explanation:
Identify the slope and y-intercept of the following equation:
3x - 2y = -10
Answer:
m=3/2,y-int=5
Step-by-step explanation:
y=mx+b is the slope equation. since -10 is at the end of the equation and it does not have a variable next to it yk it is the y-intercept. if you want you draw this on a graph and you can see that you go up 3 and over 2

oi can someone help me with this one ^{2}-12x-28=0
This is still pretty confusing for me
Answer:
Both answers should be -2 and 14.
Step-by-step explanation:
Using the quadratic formula:
[tex]x^{2}-12x-28=0\\\\x=\frac{-(-12)+-\sqrt{(-12)^2-4(1)(-28)} }{2(1)}\\\\x= \frac{12+-\sqrt{144+112} }{2}\\\\x= \frac{12+-\sqrt{256} }{2}\\\\x= \frac{12+-16 }{2}\\\\x=6+-8[/tex]
Therefore:
[tex]x_{1} =6+8=14\\x_{2}=6-8=-2[/tex]

What is an equation of the line that passes through the points (-6, 2) and (6, –2)?
Answer:
y=(-1/3)x
Step-by-step explanation:
y=mx+b
(x,y)
put in the first point into y=mx+b
2=m(-6)+b
then the second point is (6,-2)
put the point into y=mx+b
-2=6m+b
----------------------------
Put both equations in a system of equations
-2=6m+b
2=m(-6)+b
solve for m and b
-1/3=m and 0=b
so put that back into y=mx+b
y=(-1/3)x+0
so that is the only line that passes through both points

Answer:
b = 6
Step-by-step explanation:
Pythagorean formula:
a² + b² = c²
Work:
a² + b² = c²
8² + b² = 10²
64 + b² = 100
b² = 100 - 64
b² = 36

WHOEVER ANSWERS IS CONSIDERED THE BRAINLIEST QUESTION: Faye has a bag that contains 10 red, 13 blue, 16 white, 10 green, and 11 black marbles. She pulls a marble out of the bag without looking. What is the probability Faye pulls out a white marble.
SHOW WORK!
Answer:
Faye's probability of pulling out a white marble is 3/80.
Step-by-step explanation:
To find the probability, we must first add everything up. 10 + 13 + 16 + 10 + 11 = 60 marbles. Now we divide 60 by the amount of white marbles there are. 60 ÷ 16 = 3.75% or 3/80. Therefore, the probability of Faye pulling out a white marble is 3/80.

Write the equation of a line perpendicular to y= -x + 4 and that passes through point (-5,-4) in slope intercept form.
can someone please help me with this? (i will mark brainliest) (LMNP is rotated 180 degrees clockwise around the origin. what are the coordinates of L?)
Answer:
L's coordinates would go from being (x,y) to (-x, -y)
Step-by-step explanation:
So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)
If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L
Consenquently if you had a negative to begin with- L (-3, -4) L' would be the opposite sign and be (3,4)
PLEASE HELP ME I DONT UNDERSTAND!!
EVERYTHING YOU NEED TO KNOW IS ON THE IMAGE BELOW!!!
Show your work so I can mark you brainliest!!!
Step-by-step explanation:
no.1 first write the equation
the write the sum and the product
so the sum will be 8x and the product
will be 15.In the product part look for a no
that when you multiply it by another no
it will give you 15 by when you add it will
become 8.The no.is 5 and 3.you now rewrite the equation x^2+3x+5x+15=0
you now simply the equation x(x+3)+5(x+3)
you take (x+3)and (x+5)=0.
your answer will either be -3or-5 respectively
