Here, the experimental probability is 1/4 and theoretical probability is 1/18.Then the percent difference between the theoretical probability and the experimental probability is 56%.
What is probability ?The probability is a measure of chances that an event to take place.
Given that,
red marbles = 3
blue marbles =1
yellow marbles = 2
Then.
theoretical probability of selecting a blue marble followed by a yellow marble is:
P(blue and yellow) = P(blue) x P(yellow) = (1/6) x (2/6) = 1/18
Since the marbles are replaced after each draw, the probability of this event is the same for every draw.
The experimental probability of selecting a blue marble followed by a yellow marble after 40 attempts is:
(3/6) x (2/6) x (40 attempts) = 10
Therefore, the experimental probability is 10/40 = 1/4
The percent difference between the theoretical probability and the experimental probability is:
| (experimental probability - theoretical probability) / theoretical probability | x 100%
= | (1/4 - 1/18) / (1/18) | x 100%
= 0.583 x 100%
= 58.3%
Therefore, the percent difference between the theoretical probability and the experimental probability is approximately 58.3%, which is closest to the option 56%.

x=29
∠C=93°
Step-by-step explanation:
180°-52°-35°=3(x+2)°
180°-87°=(3x)°+6°
93°=(3x)°+6°
(3x)°=87°
x=[tex]\frac{87}{3}[/tex]
x=29
∠C=3(x+2)°

The base of the triangle is 4 inches more than the length of the sides and the total the total perimeter is 64 inches. Write an equation to find the length of each side of the triangle
Answer:
Both the sides are equal to 20 inches and the base is equal to 24 inches.
b=s3= s1+4----equation 1
s1=s2----equation 2
Perimeter of the triangle = s1+s2+s3--------equation 3
Step-by-step explanation:
Let the sides be denoted by s1 and s2 . Then the base is denoted by b=s3= s1+4----equation 1
According to the statement s1=s2----equation 2
Perimeter of the triangle = s1+s2+s3--------equation 3
64= s1+s2+ s1+4
64 = 3s1+4
60= 3s1
20 = s1
Both the sides are equal to 20 inches and the base is equal to 24 inches.

If these cubes are to to be placed so that their respective faces are parallel
or perpendicular, as the case may be, to the respective orientations of the
dimensions of the box, without tilting any cubes in any directions,
then choice B) can be justified. This leaves spaces (some volume) in the box
not filled by the cubes.
How many whole number of edges of the cubes fit into 4 cm?
4 / 3 √ 2 must be rounded down to 3.
How many whole number of edges of the cubes fit into 8 cm?
8 / 3 √ 2 must be rounded down to 6.
How many whole number of edges of the cubes fit into 10 cm?
10 / 3 √ 2 must be rounded down to 7.
Then (3)(6)(7) = 126
You are given m =0.4n - 2/3
What is the value of m, when n is 15?
A.0 3.7
B.4.3
C.6.0
D.8.3
Answer:
m = 5.3
Step-by-step explanation:
Given equation,
→ m = 0.4n - (2/3)
Now we have to,
→ Find the required value of m.
We have to use,
→ n = 15
Then the value of m will be,
→ m = 0.4n - (2/3)
→ m = 0.4(15) - (2/3)
→ m = 6 - (2/3)
→ m = (18/3) - (2/3)
→ m = (18 - 2)/3
→ m = 16/3
→ [ m = 5.3 ]
Hence, the value of m is 5.3.

Skylar has a collection of 60 comic books. She gave away some of her comic books to her friend. After she gave them away, she had 48 still. What percent of her comic books did Skylar give away?
Answer:
the percent of her comic books did Skylar give away is 20%
Step-by-step explanation:
Given that
Skylar has a collection of 60 comic books
She gave away some of her books
And she left by 48 books
we need to find out the percent of the skylar give away books
= (60 - 48) ÷ 60
= 12 books ÷ 60 books
= 20%
Hence, the percent of her comic books did Skylar give away is 20%

The American Water Works Association reports that the per capita water use in a single-family home is 76 gallons per day. Legacy Ranch is a relatively new housing development. The builders installed more efficient water fixtures, such as low-flush toilets, and subsequently conducted a survey of the residences. Twenty-seven owners responded, and the sample mean water use per day was 71 gallons with a standard deviation of 9.5 gallons per day. At the 0.01 level of significance, is that enough evidence to conclude that residents of Legacy Ranch use less water on average
Answer:
Yes, that is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average
Step-by-step explanation:
The data given by the American Water Works Association are;
The per capita water use in a single-family home, μ = 76 gallons per day
The number of responders in the sample, n = 27
The sample mean water used by the sample, [tex]\overline x[/tex] = 71 gallons
The standard deviation, s = 9.5 gallons per day
The level of significance, α = 0.01
The test statistics is given as follows;
The null hypothesis, H₀; μ ≥ 76 gallons
The alternative hypothesis, Hₐ; μ < 76 gallons
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
Therefore, we have;
[tex]t=\dfrac{71-76 }{\dfrac{9.5}{\sqrt{27}}} \approx -2.734817[/tex]
At n - 1 = 27 - 1 = 26 degrees of freedom, the critical-t = 2.5
From the test statistic, of t ≈ -2.734817, the p-value < 0.01, and from a graphing calculator, the p-value is given as Prob = 0.005544418
Therefore, given that the p-value is less the significant level, and less than 0.01, is therefore statistically significant, and therefore, there is sufficient statistical evidence against the null hypothesis, therefore we reject the null hypothesis, and there is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average.

Kerel wants to buy a Points card for his X-box live account. He can buy a 200-point
card for $10.00 or a 300-point card for $15.00. Which card is the better value?
Answer:
equal. i think
Step-by-step explanation:
well if 10$ is worth 200 and 15 is worth 300 for me its adding half of the orginal number (200) and get 100 so 200+100=300
Both the cards are having the same value
What is an 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.
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.
Given data ,
Let the first card be = A
Let the second card be = B
Now ,
The value of first card = $ 10.00
The value of second card = $ 20.00
And ,
The total value for 200 point cards = value of first card
The total value for 300 point cards = value of second card
So , the equation will be
200 = 10 A be equation (1)
300 = 15 B be equation (2)
Divide equation (1) by 10 on both sides , we get
A = 20
Divide equation (2) by 15 on both sides , we get
B = 20
Therefore , A = B
Hence , Both the cards are having the same value

A) 4.096 cm
B) 10 cm
C) 8.96 cm
D) 6.4 cm
Answer:
C: 8.96
Step-by-step explanation:
We know taht ZX is similar to PQ. We can now set up the ratio of 6.4: 5.12
This ratio gives us .8:1
Multiply VX by the ratio to find its corresponding similar side of RQ
