To find the outlier your have to find the IQR( interquartile range), the upper fence and the lower fence. The IQR is the difference between the first and third Quartile. Q3(7.4) -Q1(4.9)= 2.5. Use the IQR to find the Upper fence and Lower fence.
Upper fence- (7.4)+1.5(2.5)= 11.15
Lower fence- (4.9)-1.5(2.5)= -1.15
Make sure your values are in the right order so you can see what numbers are below or above the Upper and lower fences. There are no outliers.

Question

If the least value of n is 4, which inequality best shows all the possible values of n? n ≤ 4 n ≥ 4 n < 4 n > 4

Solution 1

Comment
If the least value of n is 4 that means that 4 is one of the numbers in whatever it is that you are describing. In other words n = 4 is part of your answer. If that is the case, the last two values are incorrect because 4 is not included in either one of them.

Discussion
So that means that you have to choose between one of the first 2. The key word is least. It means that the lowest possible value is 4. Nothing is lower.

When you write something like n ≤ 4 what you are saying is the n must be = to or less than 4. The arrow head points to the smallest number which, in this case, is n.

But the question says that the least number is 4. So the arrowhead must point towards the 4. This we have that n must be larger than 4.

Conditions
There are 2 conditions to this problem
n must be greater than 4
n can equal 4. It is the smallest number.

Answer
n≥4 <<<<<answer
B <<<<<< answer.

n ≥ 4

Question

which of the following mesurments are greater than 130 fluid ounces. 5 quarts, 16 cups, 9 pints, 2 gallons or 1 gallon

Solution 1

130 fluid ounces to quarts is 4.06, so 5 quarts is larger.

130 fluid ounces to cups is 16.25, so 16 cups is smaller.

130 fluid ounces to pints is 8.13, so 9 pints is larger.

130 fluid ounces to gallons is 1.02, so 2 gallons is larger and 1 gallon is smaller.

Solution 2

9 pints i'm pretty sure i'm right hope i helped

Question

A group of friends share 3 1/2 slices of cakes each friend gets half a slice of cake how many friends shared the slices of cake ? Each whole slice of cake can be divided into _____( 3 halves,1 half,2 halves) so 3 1/2 slices of cake is a total of _____ ( 4 halves,7 halves,9 halves) because each friend gets half a life of cake there are _____ (9,7,4) friends

Solution 1

Each whole slice of cake can be divided into ___2__( 3 halves,1 half,2 halves) so 3 1/2 slices of cake is a total of ___7__ ( 4 halves,7 halves,9 halves) because each friend gets half a life of cake there are __7___ (9,7,4) friends

What are proper and improper fractions and how to convert mixed fraction to simple fraction?

There is a fraction, containing numerator(upper value) and denominator(lower value).

When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction.

A proper fraction is also called fraction which is less than 1.

And an improper fraction is ≥ 1

A mixed fraction contains a sum of whole number and a proper fraction.

One example of mixed fraction is

$a\dfrac{b}{c}$

It can be taken as

$a\dfrac{b}{c} = a + \dfrac{b}{c} = \dfrac{a \times c + b}{c}$

Since it is given that there are in total $3\dfrac{1}{2}$ slices of cakes, we can convert it to normal fraction as

$3\dfrac{1}{2} = 3 + \dfrac{1}{2} = \dfrac{3 \times 2 + 1}{2} = \dfrac{7}{2} = 7 \times \dfrac{1}{2}$

This shows the amount of slices of cakes. It means there were 7 half slices of cake.

Since each friend took half slice, and all of $3\dfrac{1}{2}$ slices was consumed, thus, there must be 7 friends in the group.

Thus,

The completed statement is

Each whole slice of cake can be divided into ___2 halves__( 3 halves,1 half,2 halves) so 3 1/2 slices of cake is a total of ___7__ ( 4 halves,7 halves,9 halves) because each friend gets half a life of cake there are __7___ (9,7,4) friends

Solution 2

Answer:

Each whole slice of cake can be divided into 2 halves so $3\frac{1}{2}$ slices of cake is a total of 7 halves because each friend gets half a life of cake there are 7.

Step-by-step explanation:

Given : A group of friends share $3\frac{1}{2}$ slices of cakes each friend gets half a slice of cake.

To find : How many friends shared the slices of cake ?

Solution :

According to question,

$3\frac{1}{2}=3+\frac{1}{2}$

i.e. it divided into 2 halves.

$3+\frac{1}{2}=1+1+1+\frac{1}{2}=\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+\frac{1}{2}$

i.e. total $\frac{1}{2}$ slices are 7 halves.

Each friend gets half a life of cake

i.e. there are 7 friends.

Rounding all the statements together,

Each whole slice of cake can be divided into 2 halves so $3\frac{1}{2}$ slices of cake is a total of 7 halves because each friend gets half a life of cake there are 7.

Question

A pine tree measured 40 1/2 feet tall. Over the next 7 1/2 years,it grew to a height of 57 feet. During the 7 1/2 years, what was the average yearly growth rate of the height of the tree?

Solution 1

First subtract how tall it was 7 1/2 years ago from how tall it is now.57 - 40 1/2 =57 - 40.5 = 16.5 or 16 1/2So in the 7 1/2 years the tree grew 16 .5 or 16 1/2 feet. To get the average yearly growth for the 7 1/2 year period you have to divide the 16 1/2 feet by 7 1/2 years .It makes it much easier if you change the fractions to decimals. 16 1/2 = 16.57 1/2 = 7.516.5 ÷ 7.5 = 2.2 or 2 1/5 feet per year! :)

Question

A coin is tossed 100 times resulting in 46 heads and 54 tails. The same coin is tossed 1000 times resulting in 495 heads and 505 tails. What is the theoretical probability of getting heads with this coin?

Solution 1

Theoretically the chance of flipping a coin is still 50%. However, the likelihood based on a data set such as this is 49.18%. You can get this by adding the numbers together and dividing by the total number of times flipped.

Question

What is the difference of the two polynomials? (9x2 + 8x) – (2x2 + 3x)

Solution 1

Answer:

(9x² + 8x) - (2x² + 3x)

= 7x² + 5x

Step-by-step explanation:

(9x² + 8x) - (2x² + 3x)

open the bracket

= 9x² + 8x - 2x² - 3x

collect like terms

= 9x² - 2x² + 8x - 3x

= 7x² + 5x

Solution 2

(9x^2+8x)-(2x^2+3x)
9x^2+8x-2x^2-3x
7x^2+5x

Question

Can you discuss the differences between circumference and area of a circle ?

Solution 1

The circumference (C) of any circle is the perimeter around it; it is circles' one dimensional measurement (i.e. in, ft, cm, mi, etc.). As a circle grows, increasing the
circle's size, the distance around it (circumference) increases proportionately with
the radius. Thus this length can be found by multiplying the radius × 2 (or diameter × 1) × a constant known as pi. Pi, an infinitely long decimal that begins 3.1416, was calculated by working backwards from the length of a circle, divided by 2×radius. No matter the size of any circle, they discovered that the distance will always vary 3.1416... × twice the radius (or diameter). An example is a circle of radius 40 cm: C = 2pi×r = 80pi cm, or 251.33 cm.

The area (A) of a circle, however, covers much more matter; it is the two dimensional measure of any circle (i.e. sq.in., sq.ft, sq.cm, etc.). Area also varies according the constant pi × the radius, BUT it increases much more than the radius once; it varies by the radius × radius (radius squared) × the value pi. Using the same circle example of radius 40cm: A = pi×r^2,
A = (40×40)pi = 1600pi = 5,026.55 cm^2.

So you can see that the [2-dimensional] area of this circle is 20 times the [1-dimensional] circumference

Solution 2

The circumference of a circle is the length around the circle which is equal to 360°. Pi is the number needed to find the circumference of the circle. In circles the AREA is equal to 3.14xRadias^2

Question

ΔDEF rotates 90° clockwise about point A to create ΔD 'E 'F. Therefore, which equation must be true? m∠DEF = m∠D 'F 'E '

Solution 1

The equation that is given does not have to be true, because the letters are not in the same order. Therefore, we are not comparing the corresponding pairs of angles. They may or may not be congruent.

When a shape is rotated, the corresponding pairs of angles are congruent.

Solution 2

As Rotation does not bring any changes in the shape and size of a geometrical figure.

So, the two triangles , ΔDEF→→Called Pre image

when rotated through an angle of 90°, will be congruent to

, ΔD'E'F'→→→Called Image.

→So, when two triangles are congruent , their corresponding parts will be equal ,that is congruent.

1. ∠FD E≅∠F' D'E'

2.∠DEF≅∠D'E'F'

3.∠E FD≅∠E'F'D'

4. ED≅E'D'

5. F E=F'E'

6. FD=F'D'

All six possibilities are true when, ΔDEF rotates 90° clockwise about point A to create ΔD 'E 'F.
