In a bag there are 3 red marbles, 2 yellow marbles, and 1 blue marble. What is the likelihood of a yellow marble being selected on the first draw?
Answer:
1/3
Step-by-step explanation:
there's 6 total marbles and 2 are yellow so this can be expressed as 2/6 which can be simplified to 1/3.
hope it helps!
Answer:
1/3
Step-by-step explanation:
The total number of marbles
3 red marbles, 2 yellow marbles, and 1 blue marble = 6 marbles
P( yellow) = yellow / total
= 2/6
= 1/3
helpp me plz
thank you in advance
Answer:
1/4
Step-by-step explanation:
3 and 6 are both multiples of 3, so there is a 2/8 chance of spinning a multiple of 3, which can be simplified to 1/4.

The diameter is 112
The radius is 1/2 of the diameter
r = d/2 = 112/2 =56
The area of a circle is
A = pi r^2
= 3.14 (56)^2
=9847.04
please help me find the volume for this triangular prism
Answer:
140 yd³
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = Ah ( A is the area of the triangular face and h is the depth )
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
= 0.5 × 5 × 8 = 20 yd² , thus
V = 20 × 7 = 140 yd³

What is the complete factorization of the polynomial below?
x3 + x2 + 4x + 4
x = -1
x = 2
x = -2
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
Step by step solution :
Step 1 :
Checking for a perfect cube :
1.1 x3+x2-4x-4 is not a perfect cube
Trying to factor by pulling out :
1.2 Factoring: x3+x2-4x-4
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: x3+x2
Group 2: -4x-4
Pull out from each group separately :
Group 1: (x+1) • (x2)
Group 2: (x+1) • (-4)
-------------------
Add up the two groups :
(x+1) • (x2-4)
An isosceles trapezoid is a quadrilateral with two congruent legs, a pair of parallel bases, and congruent base angles. Prove the diagonals of an isosceles trapezoid are congruent. Be sure to create and name the appropriate geometric figures. This figure does not need to be submitted.
"When the sides are congruent (same direction and size), and the two opposite sides are parallel, the angles are the same. In an isosceles triangle, two angles are congruent, because two sides are congruent."

Answer:
i) x= -0.25, x=1.25
ii)x=1.5, x= -0.5 (notice the negative signs)
Step-by-step explanation:
So, to simply solve this(or estimate), notice what the equations say at the end of them!
0 and 2, and also notice the equations are exactly the same as the graph's.
This means, by substitution, we are look for the x-values at y=0, and at y=2
(because they are exactly the same, in those instances, we can just replace the equation with the value of 0, or 2 because they are equal)
Then all we have to do is imagine the lines of y=0(x-axis) and y=2, and find where the parabola intersects those lines.
And so, just find where they intersect, and you have got it!

Suppose that a population begins at a size of 100 and grows continuously at a rate of 200% per year. Give the formula for calculating the size of that population after t years. Question 3 options: A) A = 100 + 2et B) A = 100 + te2 C) A = 100e2t D) A = 100 + e2t
Answer:
100 (+1) x 2^t = 100 (+2et) as we plus and we multiply before squaring the years.
Step-by-step explanation:
You cna now work this out as +1 represents the 100% + 200% sum.
Answer:
C) [tex] A = 100e^{2t} [/tex]
Step-by-step explanation:
Continuous growth:
[tex] A = Pe^{rt} [/tex]
r = rate as a decimal
r = 200% = 2
P = initial value = 100

About 2.38 square feet of extra fabric: 1.25 of dark blue and 1.13 of light blue
Need $13.75 to complete template for white fabric
Step-by-step explanation:
Template requires 18 square feet of white, 20 square feet of light blue and 21 square feet of dark blue.
She has more than enough for both shades of blue fabric.
She needs 5.85 square feet more of white fabric
Since it is $2.35 per square feet of white fabric, 2.35 * 5.85 = $13.75.
It will cost her $13.75 for more white fabric

Please help! For the function f(x) = 2x^6 + 3x^4 - 4x^3 + (1/x) - sin(2x) find the first four derivatives.
Answer:
See the explanation
Step-by-step explanation:
We know that
f(x) = 2x⁶ + 3x⁴ - 4x³ + (1/x) - sin2x
Lets calculate the derivatives:
f'(x) = 6(2x⁵) + 4(3x³) - 3(4x²) -( 1/x²) - 2(cos2x)
f'(x) = 12x⁵ + 12x³ - 12x² - (1/x²) - 2cos2x
Similarly:
f''(x) = 60x⁴ + 36x² - 24x + (2/x³) + 4sin2x
f'''(x) = 240x³ + 72x - 24 - (6/x⁴) + 8cos2x
Rearrange:
f'''(x) - 240x³ +72x - (6/x⁴) + 8cos2x - 24
f''''(x) = 720x² + 72 + (24/x⁵) - 16sin2x
Rearrange:
f''''(x) = 720x² + (24/x⁵) - 16sin2x +72
The ratio of the number of A's in the class to B's in the class was 2:5. How many people got A's if there were 40 people who got B's?
Answer:
16 students got an A
Step-by-step explanation:
Set up an equation to compare the ratio to the scores:
[tex]\frac{2}{5} = \frac{x}{40}[/tex]
Cross multiply:
80 = 5x
Divide each side by 5:
x = 16
Now, check if [tex]\frac{16}{40} = \frac{2}{5}[/tex]
16/8 = 2
40/8 = 5
The ratios are the same! Therefore, 16 students got an A!
Hope this helps! Feel free to contact me if you have any questions :)

If Larry gets 5% of 80 questions wrong, how many did he get correct? Provide an explanation :)
A. 8
B. 70
C. 4
D. 76
Answer:
The answer is D.
Step-by-step explanation:
Given that Larry wrong 5% of the questions and he correct the remaining 95%. So in order to find how many questions he correct, first, you have to convert the percentage to decimal by dividing it by 100 :
[tex]95\% = \frac{95}{100} = 0.95[/tex]
Next, you have to multiply by the total number of questions :
[tex]0.95 \times 80 = 76 \: questions[/tex]
