A school creates a histogram representing the individual travel times for students riding the bus to school. The histogram is right-skewed, and the mean time is 25 minutes.
Which statement best describes the possible value of the median time of students riding the bus to school?
THIS IS THE COMPLETE QUESTION;
A school creates a histogram representing the individual travel times for students riding the bus to school. The histogram is right-skewed, and the mean time is 25 minutes.
Which statement best describes the possible value of the median time of students riding the bus to school?
The median time is less than 25 minutes.
The median time is exactly equal to 25 minutes.
The median time is approximately equal to 25 minutes.
The median time is greater than 25 minutes.
Answer;
The median time is less than 25 minutes
Step-by-step explanation
✓When the histogram is skewed right, it implies that the mean is greater than the median which means The median time is less than the mean.
This is as a result of few large values that drive as a result of skewed-right data
✓Skewness can be explained as measure of the asymmetry of a histogram When a histogram is symmetrical when it has a normal distribution, i.e when the same amount of data falls on both sides of the mean. Ahistogram has a normal distribution will have a skewness of 0.
✓the skewness can be explained in terms positive/right relationship:
√nonparametric skew implies that the mean is greater than the median, which means it is at the the right.
√A negative/left nonparametric skew can be explained as when the mean is < the median. I e it fall to the left .
Therefore, the median is less than 25 minutes
The statement that most adequately recounts the likely value of median time:
A). The median is less than 25 minutes.
What is the Median?Median is defined as the number that isolates the first and later half of a set of given distribution or number.
As per the question, the bend in the histogram towards the right side signals that the mean value is significantly higher than the median.
The cause behind this is that the greater values have caused this influence.
Hence, this implies that the median values are lesser by the time of 25 minutes.
Thus, option A is the correct answer.

rearrange w= 3(2a+b) -4 to make a the subject
Answer:
a = - 1/2b + 1/6w + 2/3
Step-by-step explanation:
w= 3(2a+b) - 4
Add 4 on both sides.
w + 4 = 3(2a+b)
Divide 3 into both sides.
w/3 + 4/3 = 2a+b
Subtract b on both sides.
w/3 + 4/3 - b = 2a
Divide 2 into both parts.
w/3/2 + 4/3/2 - b/2 = a
a = w/6 + 4/6 - b/2
a = 1/6w + 2/3 - 1/2b
Answer:
a=(w-3b+4)/6
Step-by-step explanation:
w= 3(2a+b) -4
w=6a+3b-4
6a= w-3b+4
a=(w-3b+4)/6

Which set of algebra tiles represents the sentence below? Ada drove 2 fewer miles today than she drove yesterday. 2 boxes contain negative x and 1 box contains a plus sign. 1 box contains x and 2 boxes contain a minus sign. 1 box contains negative x and 2 boxes contain plus signs. 2 boxes contain x and 1 box contains a minus sign.
Answer:
The correct option is;
1 box contains x and 2 boxes contain minus sign
Step-by-step explanation:
Algebra tiles are used in teaching students algebraic concepts. The unit (small) tile represents the number one. The rectangular tile represents the variable x and the large square tile represents x²
The parameters given are;
Ada drove 2 fewer miles today than she drove yesterday, therefore;
Let X = number of miles Ada drove yesterday
We have number of miles Ada drove today = X - 2
Therefore, the correct option is 1 box contains x and 2 boxes contain minus sign

Zaheer, a boy of height 1.5m was watching the entire programme. Initially he observed the top of theflagpoleat an angle of elevation 300 . When he moved 10 m towards the flag post the angle of elevation of the top of the flagpole increased to 450. What is the height of the flag pole?
Answer:
[tex]h = 15.163\ meters[/tex]
Step-by-step explanation:
(Assuming the correct angles are 30° and 45°)
We can use the tangent relation of the angle of elevation to find two equations, then we can use these equations to find the height of the pole.
Let's call the initial distance of the boy to the pole 'x'.
Then, with an angle of elevation of 30°, the opposite side to this angle is the height of the pole (let's call this 'h') minus the height of the boy, and the adjacent side to the angle is the distance x:
[tex]tan(30) = (h - 1.5) / x[/tex]
Then, with an angle of elevation of 45°, the opposite side to this angle is still the height of the pole minus the height of the boy, and the adjacent side to the angle is the distance x minus 10:
[tex]tan(45) = (h - 1.5) / (x - 10)[/tex]
So rewriting both equations using the tangents values, we have that:
[tex]0.5774 = (h - 1.5) / x[/tex]
[tex]1 = (h - 1.5) / (x - 10) \rightarrow (h - 1.5) = (x - 10)[/tex]
From the first equation, we have that:
[tex]x = (h - 1.5) / 0.5774[/tex]
Using this value of x in the second equation, we have that:
[tex]h - 1.5 = \frac{ (h - 1.5) }{0.5774} - 10[/tex]
[tex]h + 8.5 = \frac{ (h - 1.5) }{0.5774}[/tex]
[tex]0.5774h + 4.9079 = h - 1.5[/tex]
[tex]0.4226h = 6.4079[/tex]
[tex]h = 15.163\ meters[/tex]
Two lines AB and CD intersect at O. If ∠AOC + ∠COB + ∠BOD = 270°Find the measures of ∠AOC, ∠COB, ∠BOD, ∠DOA.
Answer:
all are 90°
Step-by-step explanation:
Vertical angles are congruent, and linear angles are supplementary, so we have ...
∠AOC + ∠COB + ∠BOD = 270°
180° + ∠BOD = 270°
∠BOD = 90°
Since the lines cross at right angles, all of the angles are 90°.
The hypotenuse of a right triangle is 9[tex]\sqrt{2}[/tex] cm, and the shorter leg is 9 cm. Find the length of the other leg.
Answer:
9 cm
Step-by-step explanation:
If you were to imagine this right triangle, you would find it to be a 45 - 45 - 90 triangle. Perhaps the " shorter leg " piece of information was present to trick you, considering that the legs are congruent by converse to base angle theorem.
How is this triangle a 45 - 45 - 90? In such a triangle, the legs can be posed as x cm, as the base angles are congruent ( 45 and 45 ), thus the legs of the triangle are congruent as well. The hypotenuse would be x√2, and as we can see -
If legs = x, Hypotenuse = x√2 = 9√2
Thus, the length of the other leg is 9 centimeters ( 9 cm )

what is the simplified value of 1/3 divied by 2/3
Answer:
1/2 or 0.5
Step-by-step explanation:
1/3 divided by 2/3
1/3 times 3/2
3/6
1/2, or 0.5
Answer:
1/2
Step-by-step explanation:
1/3 ÷2/3= 1/3×3/2( this is because fractions cannot be divided and the reciprocal of the fraction by which 1/3 had to be divided has to be taken which makes 2/3 as 3/2 and division as multiplication)
so, 1/3×3/2 gives 3/6, when simplified, gives 1/2.

You have a wire that is 50 cm long. You wish to cut it into two pieces. One piece will be bent into the shape of a square. The other piece will be bent into the shape of a circle. Let A represent the total area of the square and the circle. What is the circumference of the circle when A is a minimum
Answer:
88.6647727273 cm²
Step-by-step explanation :
The perimeter of the square =(50/2)
= 25 cm
∴ Side of the square = (25/4)
= 6.25 cm
∴ Area of of the square = (6.25)²
= 39.0625 cm²
The circumference of the circle =(50/2)
= 25 cm
∴ 2πr = 25
⇒ r = 25/(22/7)(2)
Area of the circle = (22/7) { 25/(22/7)2} {25/(22/7)2}
= (25×25×7) / (2×2×22)
= 4365/88
= 49.6022727273 cm²
∴ Total area of the circle and the square =(49.6022727273+39.0625000000)
= 88.6647727273 cm²

If yes mark BRAINLIEST!
Please please help me. I'll give you the BRAINLIEST if correct! Given the equation A=250(1.1)^t, you can determine that the interest is compounded annually and the interest rate is 10%. Suppose the interest rate were to change to being compounded quarterly. Rewrite the equation to find the new interest rate that would keep A and P the same. What is the approximate new interest rate? Convert your answer to a percentage, round it to the nearest tenth, and enter it in the space provided, like this: 42.53%
Answer:
A=250(1+2.5)^4/12
Step-by-step explanation:
A=250(1+0.1)^t
compounded quarterly : divide the annual by 4 : 0.1/4=0.025 or 2.5%
2.5% every 3 month (quarterly), t=4/12 (quarterly)
the equation will be :
A=P(1+r/n)^t (p is the principal),r is the rate, n is the number of compounding , t is the time.

which of the following represents the factorization of the trinomial below? x^2+9x-22
Answer:
(x+11)(x-2)
Step-by-step explanation:
To factorise: x^2+9x-22
You must first divide the centre term in such a way that the sum of the 2 values will be divisible by x squared and minus 22 respectively.
So x^2+9x-22 = x^2 -2x + 11x - 22.
Now factorize x^2 - 2x and 11x-22 individually.
x^2 - 2x = x(x-2)
11x - 22 = 11(x-2)
Since these both have the same value in the brackets, use 5at one of the brackets and the other is the combination of them together:
(x+11)(x-2)
Hope this helps
Answer: (x + 11)(x - 2)
Step-by-step explanation: Since the constant term is negative, it can be factored as a positive times a negative.
Before we do that however, an x will go in the first position
of each binomial because x² breaks down into x · x.
Remember, the factors of the constant term
must add to the coefficient of the middle term.
So let's list out the factors of -22.
Factors of -22
+22 · -1
-22 · +1
+11 · -2
-11 · +2
Looking at the list above, that pair
of factors that add 9 is +11 and -2.
So our answer therefore is (x + 11)(x - 2).
Note that if you wrote your answer
as (x - 2)(x + 11), it means the same thing.
The ratio of adults to children at a cricket match is 7:3.
There 150 people at the match.
How many children attended the cricket match?
Step-by-step explanation:
Ratio of adults to children= 7:3
Total no. Of people at the cricket match:150
To find the value of the ratios, 7x+3x=150 ; 10x=150 ; x=150/10:15
So, 7:3 is 7(15) adults to 3(15) children,
Total no. Of adults: 105
Total no. Of children: 45
So, as per the question, the no. Of children that attended the cricket match is 45
Which of the system(s) below works best to solve by elimination? Why? System 1 : 3m+n=71 2m-n=30
System 2 : 4x+y=1 y=-2x+9
System 3 : 5x+4y=15 5x + 11y=22
Answer:
first option is easiest since it involves just adding both equations term by term.
3m+n=71
2m-n=30
Step-by-step explanation:
The first system looks like the easiest one, because the two equations are listed already in standard form, and the variable "n" appears as positive "n" in the first equation, and as its opposite "-n" in the second equation. Therefore the elimination method works directly by adding both equations term by term (thus cancelling out completely one of the variables in the resultant/combined equation.
Please Answer Now Identify the function’s vertical asymptotes. h(x)=x-4/x^2-4 x = 2 x = 4 x = -2, x = 2 x = -4, x = 4
Answer:
x = 2 and x = +2
Step-by-step explanation:
It's essential that you use parentheses to clarify what's happening here:
h(x)=x-4/x^2-4 => h(x)=(x-4) / (x^2-4)
We have vertical asymptotes at x values at which the denominator (x^2 - 4) is zero. That would be x = 2 and x = +2.
What is the slope of a line that is perpendicular to the line whose equation is y=45x−3 A. −45 B. −54 C. 54 D. 45
Answer:
B. -5/4
Step-by-step explanation:
We're going to assume that you don't mean
y = 45x -3
which has a perpendicular line with a slope of -1/45.
Rather, we're going to assume that you mean
y = 4/5x -3
so that the slope of the perpendicular line is -5/4.
__
Similarly, we're going to assume that the answer choices are supposed to represent fractions, so that the above slope matches choice B.
_____
If the slope of a line is m, the slope of the perpendicular line is -1/m. The reciprocal of a fraction is the fraction that has numerator and denominator swapped. -1/(4/5) = -5/4.

The length of the base of a right-angled triangle ABC is 6 centimeters and the length of the hypotenuse is 10 centimeters. Find the area of the triangle.
Answer:
24
Step-by-step explanation:
Ok, so we see that we have 6 as a leg of the right triangle and 10 as the hypotenuse. As we look closer, we can tell that this makes the Pythagorean triple 6, 8, 10. 6, 8, 10 is just the Pythagorean triple 3, 4, 5 but it is multiplied by 2. So now that we know both the legs of this right triangle, we can use the area of a triangle formula (bh)/2. 6*8=48 and 48/2 = 24 which gives us our answer.
