Allyson has 4.5 pieces of rope to use for a tire swing. If each full piece is 2 2/3 feet long, how much rope does Allyson have in all?
Answer:
12 feet
Step-by-step explanation:
4.5 pieces of rope = 9/2 pieces in fractions
Also, 2 2/3 can be rewritten as 8/3 in fractions
So, 9/2 *8/3 = 72/6 = 12 feet
Allyson has 12 feet of rope in all.

Which equation represents a proportional relationship?
A) y = 2 5 x
B) y = 1 3 x + 5
C) y = −3x − 1
D) y = 2x + 0.5
Answer:
choice A: y = 25*x
Step-by-step explanation:
A proportional relationship between x and y would be y = 25*x
because y/x = 25 (a constant)
We could say that y = 2x + 0.5 can be a proportion relationship, but not between y and x directly.
y= 2* x + 2* (1/4) = 2* (x + 1/4)
and get : y / (x + (1/4) ) = 2 y and (x + (1/4)) are in a proportional relationship, except it would not be y and x .
Answer:
A) y = 2 5 x

When might it NOT be a good idea to use a dot plot to organize data?
Dot plots will not work well for large sets of data, because a dot would need to be plotted for each value.
What is interquartile range?In descriptive statistics, the interquartile range is a measure of statistical dispersion, which is the spread of the data.It is defined as the difference between the 75th and 25th percentiles of the data.Given is to investigate the disadvantage of using the dot plot to organize data.
Dot plots work very well for data with a small number of values.They would not work well for large sets of data, because a dot would need to be plotted for each value. Histograms or box plots are more useful for large sets of dataTherefore, Dot plots will not work well for large sets of data, because a dot would need to be plotted for each value.

A triangular pyramid has a base area of 24 square meters and a height of 4 meters. What is the volume of the pyramid?
Answer:
32 cubic meter
Step-by-step explanation:
Volume for any pyramid is given by following expression
volume of pyramid = 1/3( area of base of pyramid * height of pyramid)
________________________________
In the problem
base area of pyramid = 24 sq. m
height = 4 m
Therefore substituting the above given value in formula for volume of pyramid we have
volume of pyramid = 1/3( 24 sq. m * 4 m) = 8 sq. m * 4 m (since 24/3 = 8)
volume of pyramid = 32 cubic meter.
If an original quantity is 12, and the new quantity is 15, what is the percent increase?
Answer:
20% increase
Step-by-step explanation:
1- New number-original number
2- number increased divided by new number then multiply by 100
15-12= 3
3 divided by 15= 0.2
0.2 times 100= 20%
If an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.
Given that, an original quantity is 12, and the new quantity is 15.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here,
Percentage increase = (New quantity - Original quantity)/Original quantity ×100
= (15-12)/12 ×100
= 3/12 ×100
= 0.25×100
= 25%
Therefore, if an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.

The rule is called a "position to term" rule. That means the word "position" is being used to identify the location of a term in the sequence. The first term is in position 1, for example. Using the rule that the position is multiplied by 6, then 10 is subtracted, we find the terms to be as follows.
In position 1, the term is ...
1×6 -10 = -4
In position 2, the term is ...
2×6 -10 = 2
In position 3, the term is ...

Anthony surveys a group of students at his school about whether they play a sport...
Answer:
Yes they are independent, because P(girl) ≈ 0.42 and P(girl l plays a sport) ≈ 0.42
Step-by-step explanation:
A.P.E.X
Yes, being a girl and playing a sport are independent events as P(girl) = P(girl plays a sport) = 0.4
What is mean by Probability?The term probability refers to the likelihood of an event occurring. It is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Given that;
We have been given a table that shows the results broken down by gender.
Play sports Do not play sports Total
Boy 105 75 180
Girl 70 50 120
Total 175 125 300
Here, Formula for probability of independent events:
"If A and B are independent events then, P(A∩B) = P(A).P(B)"
And, Formula of the probability of an event A is:
⇒ P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.
Now, Using the definition of probability:
⇒ P(girl) = Number of girls/ Number of students
⇒ P(girl) = 120/300
⇒ P(girl) = 0.4 .....(1)
And, we find the probability of girls that play a sport.
Using the definition of probability:
P(girl plays a sport) = Number of girls who plays a sport/ number of students who plays a sport
= 70/ 175
= 0.4 ...(2)
From (1) and (2),
P(girl) = P(girl plays a sport)
Thus, Being a girl and playing a sport are Independent events.

The history test has 19 questions. There are
true or false questions worth 4 points each
and multiple-choice questions worth 6 points
each. How many multiple-choice questions
are on the 100 point test?
Answer:
12 multiple choice questions
Step-by-step explanation:
The system of equations is:
m + t = 19 (quantity of questions)
6m + 4t = 100 (point value)
We use elimination to solve.
Multiply everything in the first equation by 4.
4m + 4t = 76.
subtract that from the second equation.
2m = 24
Divide both sides by 2.
m = 12
Answer:
Step-by-step explanation:
Let x be the number of true or false questions.
Let y be the number of multiple choice questions
Total questions = 19
x + y = 19 ---------------(i)
Total points = 100
4x + 6y = 100 ---------------(ii)
Multiply equation (i) by (-4).
(i)*(-4) -4x - 4y = -76
(ii) 4x + 6y = 100 {Now add. thus x will get eliminated}
2y = 24
y = 24/2
y= 12

A restaurant charges $3 for a soda and it includes free unlimited
refills. If this situation were represented as a function, what would be
the slope?
1)O
2)3
3)5
4)7
In this situation, where the price of the soda remains constant regardless of the number of refills, the slope of the function representing this scenario is 0.
Explanation:In mathematics, the slope of a function can be thought of as the rate of change of the dependent variable (in this case, cost) in relation to the independent variable (in this case, number of refills). Given that the price for the soda remains constant at $3 regardless of the number of refills, the slope would be 0. This is because the cost (the y-value) does not change as the number of sodas (the x-value) increases. Thus, the correct answer is 1) 0.

It takes 12.5 mL of a 0.30 M HCl solution to neutralize 285 mL of NaOH solution.
What is the Molarity concentration of the NaOH solution?
13.15 M NaOH
1.5 M NaOH
0.15 M NaOH
0.013 M NaOH
Answer:
0.013 M NaOH
Step-by-step explanation:
HCL + NaOH = NaCL + water
The mole ratio of acid and base is 1:1
Molarity is equal to the moles of solute divided by the liters of solution
Solute mole = 12.5 × 10^-3 × 0.3
= 0.003075
To neutralize 0.00375mol of HCl, 0.00375 mol of NaOH will be required. Since molarity is moles per liter, divide this amount of moles by the volume in liters:
Molarity = 0.00375/285 × 10^-3
Molarity = 0.0131 M
The molarity concentration of the NaOH solution is 0.013M NaOH
The equation of reaction is given as:
[tex]HCl + NaOH >>>>>> NaCl + H_2O[/tex]
Concentration of Hcl, [tex]C_{Hcl}=0.30M[/tex]
Volume of Hcl, [tex]V_{HCl}=12.5mL[/tex]
Concentration of NaOH = [tex]C_{NaOH}[/tex]
Volume of NaOH, [tex]V_NaOH = 285mL[/tex]
From the equation of reaction:
Number of moles of Hcl, [tex]n_{HCl}=1[/tex]
Number of moles of NaOH, [tex]n_{NaOH}=1[/tex]
The formula for neutralization is given as:
[tex]\frac{C_{HCl}V_{HCl}}{C_{NaOH}V_{NaOH}} = \frac{n_{HCl}}{n_{NaOH}}[/tex]
Substitute the values of the parameters
[tex]\frac{0.30(12.5)}{C_{NaOH}(285)} =\frac{1}{1} \\\\C_{NaOH}(285) = 0.30(12.5)\\\\C_{NaOH}(285) = 3.75\\\\C_{NaOH}=\frac{3.75}{285} \\\\C_{NaOH} = 0.013M[/tex]
