The data set below has a lower quartile of 13 and an upper quartile of 37.1, 12, 13, 15, 18, 20, 35, 37, 40, 78

Which statement is true about any outliers of the data set?

The data set does not have any outliers.

The lowest value, 1, is the only outlier.

The greatest value, 78, is the only outlier.

Both 1 and 78 are outliers.

Answers

Answer 1

Answer:

Answer:

The correct option is 3.

Step-by-step explanation:

The first and third quartile of the data are 13 and 37.

The interquartile range is the difference between Q₃ and Q₁.

$\text{Interquartile Range}=Q_3-Q_1$

$\text{Interquartile Range}=37-13=24$

We have to find 1.5 (IQR),

$1.5* \text{Interquartile Range}=1.5* 24=36$

Now subtract 36 from Q₁ and add 36 in Q₃, if data lies outside the interval [Q₁-1.5(IQR),Q₃+1.5(IQR)] are called outliers.

$Q_1-36=13-36=-23$

$Q_3+36=37+36=73$

The outliers are the numbers which lies outside the range [-23,73]. Only 78 lies outside the range, therefore the correct option is 3.

26. A public park is in the shape of a triangle. The side of the park that forms the base of the triangle is 2000 yards long, and the area of the park is 7500 yards2 . What is the length of the side of the park that forms the height of the triangle?

Answers

Answer:

7.5 yards

Step-by-step explanation:

Since the area of a triangle is found by the equation: $(bh )/(2)$ , in which b=base h=height, and $bh$ is base times height, we can work backward from the value of the area to find the height of the park

Start by multiplying 7500 by 2. From this, you get 15000.

Now for the second step, you have to divide 15000 by 2000 in order to determine the height of the triangle. this value comes out to 7.5.

This means that the values of the equation are b=2000 and h=7.5 $(2000(7.5))/(2)$

To double-check, we multiply 2000 by 7.5. and divide that value by 2. This gives us the original area of 7500

This means that the height of the park is 7.5 yards

y = (2/3)x - 1/3
y + 1/3 = (2/3)x
(3/2)*(y+1/3) = x
(3/2)y + 1/2 = x

f^-1(x) = (3/2)x + 1/2
This is the inverse you need to graph. You can plot this yourself, or use a graphing calculator.

The domain of f^-1(x) is all real numbers
The range of f^-1(x) is all real numbers

For the next 2, just plug in the values and solve:

f(2) = 1
f^-1(-19) = -28

Hamid has gained weightHe now weighs 88kg, which is 10% higher than his normal weight.

What is Hamid's normal weight?

Answers

If we let x be Hamid's normal weight, 10% of the normal weight can be expressed as 0.10x. The equation that would let us better visualize the problem,
(1.10)x = 88

The value of x from the equation is 80.

Therefore, the answer is 80 kg.

The normal weight of Hamid is 80 kg.

Step-by-step explanation:

Given information:

The current weight of Hamid is 88 kg.

Let , $W$ is the normal weight of hamid.

Now , if he is having 10% extra weight

So,

The value 88 is sum of normal weight and 10% of the normal weight

So,

$W+0.10* W=88\n1.10* W=88\nW=80$

Hence, the normal weight of Hamid is 80 kg.

The calculated value of the area of the parallelogram is 99 square cm

Calculating the area of the parallelogram

From the question, we have the following parameters that can be used in our computation:

The parallelogram

Where we have

Height = 11 cm

Base = 5 cm + 4 cm = 9 cm

The area of the parallelogram is calculated as

Area = Base * Height

Substitute the known values in the above equation, so, we have the following representation

Area = 11 * 9

Evaluate the product of 11 and 9

So, we have the following representation

Area = 99

Hence, the area of the parallelogram is 99 square cm
