The set 2 contains an outlier.
The range measure of spread was most impacted by the outlier.
What is the box-and-whisker plot?A box and whisker plot displays a "box" with its left edge at Q₁, right edge at Q₃, "center" at Q₂ (the median), and "whiskers" at the maximum and minimum.
Given:
Set 1: 8, 15, 13, 7, 11, 17, 13
Median = 13
Lower quartile = 8
Upper quartile = 15
Range = 10
Interquartile range = 7
And Set 2: 8, 15, 13, 7, 11, 17, 13, 100
Median = 13
Lower quartile = 9.5
Upper quartile = 16
Range = 93
Interquartile range = 6.5
Set two contains the value 100 as an outlier.
The range is the component of spread that was most adversely affected by the outlier.
This is due to the fact that set two's median, quartiles, and interquartile range are all closely clustered together, but the range is 93, which is extremely disproportional high compared to any of those other numbers.
Therefore, set 2 contains an outlier.

(3x+5) is a factor of the polynomial (a-1)x^3 + (a+1)x^2 - (2a + 1)x - 15. Find the value of 'a'. For this value of 'a', factorize the given expression completely.
Answer:
(3x + 5)(x + √3)(x - √3)
Answer:
a = 4
Step-by-step explanation:
(3x+5) is a factor of the polynomial (a-1)x³ + (a+1)x² - (2a + 1)x - 15
Means x = -5/3 is a root
(a-1)(-5/3)³ + (a+1)(-5/3)² - (2a + 1)(-5/3) - 15 = 0
-125a/27 + 125/27 + 25a/9 + 25/9 + 10a/3 + 5/3 - 15 = 0
a(-125/27 + 25/9 + 10/3) = 15 - 5/3 - 25/9 - 125/27
a(40/27) = 160/27
a = 4

We have 2 stacks or styrofoam cups one has 6cups and it's height is 15cm.The other stack has 12cups and Height is 23cm. How many cups are needed for a stack with the height of 50cm?
Answer:
Given
Number of stacks = 2
Stack 1 = 6 cups; h1 = 15cm
Stack 2 = 12 cups; h2 = 23cm
Let's first find the average:
[tex] \frac{H_1 - H_2}{ n_1 - n_2}[/tex]
[tex]= \frac{15-23}{6-12} [/tex]
[tex] = \frac{-8}{-6} = \frac{4}{3} [/tex]
With an average of 4/3, to obtain the number of cups needed to obtain a height of 50m, we have:
50 / (4/3)
= 50 * 3/4
= 150/4
= 37.5
From the answer, we can see that the number of cups is not really proportional to the height of the stack, because the average of stack one and stack 2 are different.
The volume of a cone of radius r and height h is given by V=πr²h³. If the radius and the height both increase at a constant rate of 12 cms/sec, at what rate, in cubic centimeters per second, is the volume increasing when the height is 9 centimeters and the radius is 6 centimeters?
Answer:
The volume of cone is increasing at a rate 1808.64 cubic cm per second.
Step-by-step explanation:
We are given the following in the question:
[tex]\dfrac{dr}{dt} = 12\text{ cm per sec}\\\\\dfrac{dh}{dt} = 12\text{ cm per sec}[/tex]
Volume of cone =
[tex]V = \dfrac{1}{3}\pi r^2 h[/tex]
where r is the radius and h is the height of the cone.
Instant height = 9 cm
Instant radius = 6 cm
Rate of change of volume =
[tex]\dfrac{dV}{dt} = \dfrac{d}{dt}(\dfrac{1}{3}\pi r^2 h)\\\\\dfrac{dV}{dt} = \dfrac{\pi}{3}(2r\dfrac{dr}{dt}h + r^2\dfrac{dh}{dt})[/tex]
Putting values, we get,
[tex]\dfrac{dV}{dt} = \dfrac{\pi}{3}(2(6)(12)(9) + (6)^2(12))\\\\\dfrac{dV}{dt} =1808.64\text{ cubic cm per second}[/tex]
Thus, the volume of cone is increasing at a rate 1808.64 cubic cm per second.
Final answer:
The volume of a cone can be found using the formula V = πr²h³. To find the rate at which the volume is increasing, we differentiate the volume formula with respect to time and substitute the given values into the derivative formula. The volume is increasing at a rate of 15552π cubic centimeters per second.
Explanation:
To find the rate at which the volume is increasing, we need to differentiate the volume formula with respect to time.
Let's differentiate the volume formula V = πr²h³ with respect to time t:
dV/dt = π(2rh³(dr/dt) + r²h²(dh/dt))
Given that dr/dt = dh/dt = 12 cm/sec, r = 6 cm, and h = 9 cm, we substitute these values into the derivative formula:
dV/dt = π(2(6)(9³)(12) + (6²)(9²)(12))
dV/dt = π(11664 + 3888)
dV/dt = 15552π
Therefore, the volume is increasing at a rate of 15552π cubic centimeters per second.

The number of pupils in school A is equal to half the number of pupils in school B. The ratio of the boys in school A and the boys in school B is 1:3 and the ratio of the girls in school A and the girls in school B is 3:5. The number of boys in school B is 200 higher than the number of boys in school A. Find the number of boys and girls in each school.
Answer:
There are 100 boys and 300 girls in School A and there are 300 boys and 500 girls in School B .
Step-by-step explanation:
The ratio of the boys in school A and the boys in school B is 1:3
Let the ratio be x
No. of boys in School A = x
No. of boys in School B = 3x
We are given that The number of boys in school B is 200 higher than the number of boys in school A.
So,[tex]x+200=3x[/tex]
[tex]200=3x-x[/tex]
[tex]200=2x[/tex]
[tex]\frac{200}{2}=x[/tex]
100=x
So, No. of boys in School A = x = 100
No. of boys in School B = 3x =3(100)=300
We are given that the ratio of the girls in school A and the girls in school B is 3:5.
Let the ratio be y
So, No. of girls in School A = 3y
No. of girls in School B = 5y
So, Total No. of students in School A= No. of boys in school A + No. of girls in school A=100+3y
Total No. of students in School B= No. of boys in school B + No. of girls in school B=300+5y
We are given that The number of pupils in school A is equal to half the number of pupils in school B.
So, [tex]100+3y=\frac{1}{2}(300+5y)[/tex]
[tex]200+6y=300+5y[/tex]
[tex]y=100[/tex]
No. of girls in School A = 3y=3(100)=300
No. of girls in School B = 5y=5(100)=500
Hence there are 100 boys and 300 girls in School A and there are 300 boys and 500 girls in School B .
Answer: 100 boys, 300 girls in School A. 300 boys,500 girls in School B

Volume = length × width × height
336 = 4 × 7 × height
height = 12
Answer:
12 cubic inches.
Step-by-step explanation:
Since volume is length x width x height, you just do 7 x 4 (28) and then the total, 336 and divide that by 28. So, 12 cubic inches!
3. The annual per capita consumption of fresh bananas in the United States can be approximated by a normal distribution, with a mean of 10.4 pounds and a standard deviation of 3 pounds. What is the largest annual per capita consumption of bananas that can be in the bottom 5 % of consumption
Answer:
The largest annual per capita consumption of bananas in the bottom 5% of consumption is 5.465 lb
Step-by-step explanation:
Given
μ = Mean = 10.4 lb
σ = Standard deviation = 3 lb
Using a confidence level of 90%,
We'll need to first determine the z value that correspond with bottom 5% of consumption of banana
α = 5%
α = 0.05
So,
zα = z(0.05)
z(0.05) = -1.645 ----- From z table
Let x represent the largest annual per capita consumption of bananas
The relationship between x and z is
x = μ + zσ
By substitution;
x = 10.4 + (-1.645) * 3
x = 10.4 - 4.935
x = 5.465
Hence, the largest annual per capita consumption of bananas in the bottom 5% of consumption is 5.465 lb

Which one is bigger 4.5 kg or 4.050
Answer:
4.5 kg
Step-by-step explanation: if you have 4.050 take off the zero and it is only 4.05 which is less then 4.5 or 4.50
Final answer:
When comparing 4.5 kg to 4.050 kg, 4.5 kg is the larger weight since both are in kilograms and 4.5 is greater than 4.050.
Explanation:
The question asks which number is larger, 4.5 kg or 4.050 kg. In the metric system, weights are compared directly as they are expressed in the same units. Here, we compare 4.5 to 4.050. Since 4.5 can also be thought of as 4.500 when considering the decimal places, it becomes clear that 4.5 kg is the larger value because both represent kilograms, and 4.5 is greater than 4.050.

Marta and Kim are sisters. Five years ago Kim's age was twice as great as martas age. If Marta is no m years old, what expression represents Kim's age now?
Answer:
y = 2m-5
Kim's age now is y = 2m-5
Step-by-step explanation:
Let m represent martas age now and y represent Kim's age now
Given;
Five years ago Kim's age was twice as great as martas age.
(y-5) = 2(m-5)
Solving for y;
y-5 = 2m-10
y = 2m-10+5
y = 2m-5
Kim's age now is y = 2m-5
Final answer:
Kim's current age is represented by the expression 2m - 5, where m is Marta's current age. This is determined by considering the age difference and relationship of their ages five years ago.
Explanation:
The question is about determining Kim's current age given that Marta is currently m years old and five years ago Kim's age was twice that of Marta's. To solve this, we can follow these steps:
Let's represent Marta's age five years ago as m - 5.
Since Kim's age was twice Marta's age five years ago, we express Kim's age at that time as 2(m - 5).
To find Kim's current age, we add five years to her age at that time: 2(m - 5) + 5.
Simplifying the expression gives us Kim's current age as 2m - 5.
Therefore, the expression that represents Kim's age now, given that Marta is m years old, is 2m - 5.
Bottles of a popular cola drink are supposed to contain 300 ml of cola. There is some variation from bottle to bottle because the filling machinery is not perfectly precise. The distribution of the contents is normal with standard deviation of 3 ml. A student who suspects that the bottler is under-filling measures the contents of six bottles. The results are:299.4 297.7 301.0 298.9 300.2 297.0Is this convincing evidence that the mean contents of cola bottles is less than the advertised300 ml? Test at the 5% significance level.
Answer:
No because there is sufficient statistical evidence to suggest that the mean contents of cola bottles is equal to 300 ml as advertised
Step-by-step explanation:
Here we have the measured contents as
299.4
297.7
301.0
298.9
300.2
297.0
Total = 1794.2
∴ Mean = 299.03
Standard deviation = 1.5
We have
[tex]z=\frac{\bar{x}-\mu }{\frac{\sigma }{\sqrt{n}}}[/tex]
Where:
[tex]\bar x[/tex] = Mean of sample = 299.03 ml
μ = Mean of population = 300 ml
σ = Standard deviation of population = 3 ml
n = Sample size = 6
α = 5% = 0.05
We set our null hypothesis as H₀ = 300 ml
Our alternative hypothesis is then Hₐ < 300 ml
Therefore, z = -0.792
The probability from z table is P = 0.2142
Since the P value, 0.2142 is > than the 5% significance level, 0.05 we accept the null hypothesis that the mean contents of cola bottles is 300 ml.

Ryan charges his neighbors $17.50 to wash their car. How many cars must he wash next summer if his goal is to earn at least $1,500?
Answer:
86 cars
Step-by-step explanation:
1,500/17.50=85.71 so you just round it a little
He must wash 86 cars.
What is division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items. It is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups.
Example: 4 / 2 = 2.
Given, Ryan charges his neighbors $17.50 to wash their car.
So, he earns $17.50 per car.
Let Ryan washes x cars to earn $1500
$17.50(x)=$1500
x = $1500/$17.50
x = 85.71 ≈ 86
Hence, Ryan needs to wash 86 cars to earn at least $1500.

The estimated size of the lemur population can be calculated using the mark and recapture technique.
Explanation:The estimated size of the lemur population can be calculated using the mark and recapture technique. The formula to estimate population size is:
N = (M * C) / R
where N is the estimated population size, M is the number of marked individuals in the second capture, C is the total number of individuals in the second capture, and R is the number of marked individuals recaptured in the second capture.
In this case, the number of marked individuals in the second capture is 11, the total number of individuals in the second capture is 49, and the number of marked individuals recaptured is 11. Plugging these values into the formula:
N = (11 * 49) / 11 = 49
Rounding to the nearest whole number, the estimated size of the lemur population is 49.
