Answer:
[tex]\dfrac{2}{9}[/tex]
Step-by-step explanation:
Given that,
A bag contains 5 blue, 2 white and 2 yellow marbles.
We need to find the probability of choosing a white marble from the bag.
Total no. of outcomes = 5+2+2
= 9
No. of white marbles = 2
Required probability,
[tex]P=\dfrac{2}{9}[/tex]
So, the probability of choosing a white marble is equal to [tex]\dfrac{2}{9}[/tex].
I need help im doing IXL right now (BB.3 Complete a function table: quadratic functions)

Answer:
0, 2, 4
Step-by-step explanation:-2 + 2 = 0 + 2= 2 + 2 = 4
The function table is solved and the quadratic equation is f ( x ) = -3x²
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
f ( x ) = -3x²
when x = -2
f ( -2 ) = -3 ( -2 )²
f ( -2 ) = -12
And , when x = 0
f ( 0 ) = 0
when x = 2
f ( 2 ) = -12
when x = 4
f ( 4 ) = -48
Hence , the function table is f ( x ) = { -12 , 0 , -12 , -48 }

Find the discount savings on a bicycle that originallycosts $230 but is on sale for 40% off. Show yourwork.
Answer:
You would save 92$
Step-by-step explanation:
Discount = Original Price x Discount 40/100
Discount = 230 × 40/100
Discount = 230 x 0.4
You save = $92.00
Final Price = Original Price - Discount
Final Price = 230 - 92
Final Price = $138.00

10. You currently have $40 dollars. You make $7.50 per hour at your part-
time job. If you worked 5 hours on Friday, 6 hours on Saturday, and 4 hours
on Sunday, how much money do you have in total?
Answer:
(B) $152.50
Step-by-step explanation:
Friday: 5 hours x $7.50 per hour = $37.50
Saturday: 6 hours x $7.50 per hour = $45
Sunday: 4 hours x $7.50 per hour = $30
$40 + $37.50 + $45 + $30 = $152.50
I would have (B) $152.50 in total.

Find the area of the triangle.
Answer:
66cm²
Step-by-step explanation:
The figure shown is actually a parallelogram
The area of a parallelogram can easily be calculated by multiplying the base length by the height
For this parallelogram the height given is 6 cm and the base length given is 11cm
so area = 6 * 11
6 * 11 = 66
hence the area of the parallelogram is 66cm²

The cost of a holiday is £2400. Rana pays a deposit followed by monthly payments, in the ratio deposit:total of the monthly payments=3:5 she makes 6 equal monthly payments. Work out her monthly payment
Answer:
Monthly installments = £250
Step-by-step explanation:
Given
Total cost of holiday = £2400
Ratio deposit : total of the monthly payments=3:5
Total deposit made = [tex]\frac{3}{3+5} * 2400 = 900[/tex]
Total amount of the monthly payments = 2400 -900 = 1500
She pays six equal installments.
Amount of installments = 1500/6 = 250
Monthly installments = £250
Using proportions, it is found that her monthly payments are of £250.
The deposit is of x.The total of monthly payments the remainder, that is, 2400 - x.According to the ratio, we have that:
[tex]\frac{x}{2400 - x} = \frac{3}{5}[/tex]
Applying cross multiplication:
[tex]5x = 3(2400 - x)[/tex]
[tex]8x = 7200[/tex]
[tex]x = \frac{7200}{8}[/tex]
[tex]x = 900[/tex]
Hence, the monthly payments add to £1500.
She makes 6 equal monthly payments, hence:
[tex]p = \frac{1500}{6} = 250[/tex]
Her monthly payments are of £250.

Answer:
Volume of box V = 180 cm^3
Base area of box A = 36 cm^2
Height = h
Volume = base area × height
height = volume/base area
h = V/A
Substituting the values;
h = (180cm^3)/(36cm^2)

What fraction of the dunk tanks require at least 500 gallons of water? Write the fraction in simplest form.
Answer:
1/2
Step-by-step explanation:
Based on the information observed from the attached box and whisker plot, the Fraction of dunk tanks which requires atleast 500 gallons of water. This fractional value will be the property of plot in the position marked as 500 on the plot. The point which refers to 500 gallons on the plot is the ticked point in between the box. This point represents the median value in a box and whisker plot.
The median value represents the 50th percentile value which relates to half of the distribution. This means that fraction of dunk which requires atleast 500 gallons is : (50/100) = 1/2
What is the likelihood that a point chosen inside the square will also be inside the circle ?It Chose one : A. is impossible ,B. it is unlikely, C it is likely D. it is certain

C. It is likely
Step-by-step explanation:
Given
See attachment for diagram
For the square.
Let
[tex]Length = L[/tex]
So, the area is:
[tex]Area = Length^2[/tex]
[tex]A_1=L^2[/tex]
The side length of the square equals the diameter of the circle.
So:
[tex]diameter (d) = L[/tex]
The radius is:
[tex]r = \frac{1}{2}d[/tex]
[tex]r = \frac{1}{2}L[/tex]
The area is:
[tex]Area = \pi r^2[/tex]
[tex]A_2 = \pi * (\frac{1}{2}L)^2[/tex]
[tex]A_2 = \pi * \frac{1}{4}L^2[/tex]
[tex]A_2 = \frac{22}{7} * \frac{1}{4}L^2[/tex]
[tex]A_2 = \frac{22}{28} L^2[/tex]
The likelihood that a point will be common to the square and the circle is:
[tex]Pr = \frac{A_2}{A_1}[/tex]
[tex]Pr = \frac{\frac{22}{28} L^2}{L^2}[/tex]
[tex]Pr = \frac{22}{28}[/tex]
[tex]Pr = 78.57\%[/tex]
The above probability is greater than 50% but less than 100%.
Hence, it is likely
Answer:
C. Likely
Step-by-step explanation:
all the points are in the circle so it's likely to choose a point inside the circle

Victor bought a new soccer ball. The original price was $29.99, but the ball was on sale for 15% off. What was the sale price?
Answer:
Sale price= $25.5
Step-by-step explanation:
Giving the following information:
The original price was $29.99, but the ball was on sale for 15% off.
To calculate the sales price, we need to use the following formula:
Sale price= original price* (1 - sales discount)
Sale price= 29.99*(1 - 0.15)
Sale price= $25.5

Simplify; (³√729)³ + 24
Answer:
[tex](\sqrt[3]{729} )^{3}[/tex] + 24 can be simplified to 753.
Step-by-step explanation:
If you take the root of a number to a specific number, then square that by the same number you took the root by, then you will have the same number you started with. In this case, [tex]\sqrt[3]{729}[/tex] equals 9, and [tex]9^{3}[/tex] equals 729, so [tex](\sqrt[3]{729} )^{3}[/tex] equals 729. 729 + 24 = 753, so that is the simplified answer.

A football quarterback goes for a two-point conversion when the ball is within 10 yards of the end zone. During the game, he has two opportunities for a two-point conversion. He misses the first attempt 50% of the time. When he misses the first attempt, he misses the second attempt 15% of the time. What is the probability of missing both two-point conversion attempts?
Answer:
P = 0.075 P = 7.5%
Step-by-step explanation:
We pretty much look for the probability that the player fails the first attempt and also fails the second attempt.
We know for a fact that the probability that the quarterback fails the first attempt is:
p(1) = 0.5
and we know that the probability that the quarterback fails the second attempt after failing the first is:
p(2/1) = 0.15
Then the probability of failure of both attempts is:
P(2/1) = p(1 and 2) / p(1)
p(1 and 2) = P(1) * P(1/2)
p(1 and 2) = 0.5 * 0.15
and that is
p(1 and 2) = 0.075
