A standard die is rolled 12 times and a 2 comes up 3 times. The experimental probability of rolling a 2 with this die is?
Answer:
1/4
Step-by-step explanation:
Number of trials = 12
Number of successes = 3
Experimental probability = (Number of successes / total number of trials)
Hence,
Experimental probability of obtaining a 2:
= 3 / 12
= 1/4

Sarah is selling bracelets and necklaces to make money for her summer vacation. The bracelets cost $2 and the necklaces cost $3. She needs to make more than $500. Sarah knows that she will sell greater than 50 bracelets. Which of the following choices would be a system of inequalities for Sarah’s situation?
Answer:
85 Necklaces and ----- Bracelets.
Step-by-step explanation:
500 Divided by 2 = 250, The 500 is the amount in total,The 250 is the amount of bracelets and necklaces needed for 500$ To be a accurate number for 'Sarah's ' Situation. Now 250 divided by 2 is 125. It was divided by 2 so it can be the amount the bracelets cost. Or instead of dividing to get 250, You can multiply and do 2x125=250, So them add Go on from there, Its not to hard but if you need more help I'm here!
Now for the necklace portion of it. 3x80=240, So she sold 80 necklaces. Than sold 3 more. Now you have a total of 250.

Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid). The building has a 64×64 m end text square base and is 36 m tall. The cut off section has a16×16m square base and is 12 m tall. What is the volume of the building? Round to the nearest cubic meter.
Area of full pyramid: = 1/3 x area of base x height
Area = 1/3 x 64^2 x 36 = 49,152 cubic meters
Area of top section: 1/3 x 16^2 x 12 = 1,024 cubic meters
Total volume of truncated pyramid = 49,152 - 1,024 = 48,128 cubic meters

Answer:
x= -3/2 or x=1.
Step-by-step explanation:
First, make the equation into a factorable form by subtracting 2 from each side to get 2x²+x-3=0. Then factor that into (2x+3)(x-1)=0. Then, you would do 2x+3=0, 2x=-3, x= -3/2. After that, do the second equation x-1=0, x=1.

Solve for x.
-3(4x-16)=-12
I need an answer and explanation so I can try to do some myself thanks!:)
Answer:
B. -5
Step-by-step explanation:
this is quite simple, so what you are going to want to do is multiply -3 by 4, and -16, so distribute that and you'll end up with
-12x+48= -12
then you want to subtract 48 from both side to leave the x on one side alone
that will be -12x= -60
after that you have to divide both sides by -12 to find your x
so then you will see that your x is = -5! hope this helps!!
The area of a rectangle is represented by 3x^2 + 14x + 8. Factor the area to determine the dimensions of the rectangle.
Answer:
(3x+2)(x+4)
Step-by-step explanation:
(3x+2)(x+4) = (3x)(x) + (3x)(4) + (2)(x) + (2)(4)
= 3x² + 12x + 2x + 8 *****
= 3x² + 14x + 8
You start by figuring it will be in the form of (3x + a)(x + b) because 3 doesn't factor. The two middle terms in the line followed by the stars must add up to 14x. And in (3x + a)(x + b), ab must be equal to the 8 on the end (the constant factor).
For most people, factoring takes a LOT of practice. And somethimes you just have to try a lot of factors before you hit the right combination. But if you do it enough, it really does get easier to 'see' the answer a lot of the time.
Hope this helped!

Brian and Mark are fishing. They both catch a fish. Brian's fish weighs 17
pounds less than Mark's fish. Mark's fish weighs 22 pounds
PLEASE HURRY.
Answer: 5 pounds
Step-by-step explanation:
We need to find how much Brian's fish weighs. We know that Mark's fish weighs 22 pounds, and Brian's fish weighs 17 pounds less than Mark's fish. To find how much Brian's fish weighs, we can subtract 17 from 22.
22 - 17 = 5.
Therefore, Brian's fish weighs 5 pounds.
Hope this helps, and good luck :D
Answer:

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
The taxi charges $3 just for the pickup and then an additional $1 per mile driven.
let the taxi drive total x miles then the charges will be
P = 3 + x
Now, for 4 miles put the value of x = 4.
So, P = 3 + 4
P = $7
and, For m miles ride the taxi would cost
P= 3 + m.

10. Multi-Step Mrs. Sullivan calculates that she
needs 12 gallons of paint to paint her house.
She already has 8 quarts of the paint she
needs. How many gallons of paint should
she buy?
Answer:
Amount of paint to be bought = 10 gallons
Step-by-step explanation:
Amount of paint needed by Mrs. Sullivan to paint her house = 12 gallons
She is already having paint = 8 quarts
Since, 1 quart = 0.25 gallons
Therefore, 8 quarts = 8 × 0.25
= 2 gallons
So, amount of paint she is already having = 2 gallons
Amount of paint to be bought = 12 - 2
= 10 gallons
