Mixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers. the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].
Given information;
The mixed numbers given is the problem are [tex]8\dfrac{1}{3} [/tex] and [tex]2\dfrac{2}{3} [/tex]
Mixed numberMixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers.
Now the given mixed number has to be divided. This number can be divided by converting into the proper fraction numbers. Let I is the result when the two numbers are divided. Thus,
[tex]x=8\dfrac{1}{2} \div 2\dfrac{2}{3} \\ [/tex]
To solve this convert the mixed numbers into the fraction number. For this multiply the denominator to the whole number and then add in the numerator. Thus,
[tex]x=\dfrac{16+1}{2} \div \dfrac{6+2}{3} \\ x=\dfrac{17}{2} \div \dfrac{8}{3} \\ [/tex]
Convert the divide sign into the multiply sign by changing the numerator to the denominator of one of the fraction.
[tex]x=\dfrac{17}{2}\times \dfrac{3}{8} \\ x=\dfrac{51}{16}\\[/tex]
As 16 can divide the number 51 in 3 times with reminder 3. Thus the mixed number for the above fraction can be written as,
[tex]x=3\dfrac{3}{16}[/tex]
Thus the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

9. What is the range of the relation [(4, 2), (1, 1), (0, 0). (1.-1). (4, -2) ?
Answer:
{-2,-1,0,1,2}
Step-by-step explanation:
When we are talking of the range, we are referring to the possible y-values the relation can take
Hence, a set of y-values will represent the range of the relation
we have this as:
{2, 1 , 0, -1 , -2}
Arranging in order, we have ;
{-2,-1,0,1,2}

C
A random sample of 75 taken from a population distribution that is skewed to the left
A random sample of 75 taken from a population distribution that is skewed to the left
D
A random sample of 100 taken from a population that is uniform
Answer:
C
Step-by-step explanation:
Using the Central Limit Theorem, it is found that the option in which is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal is:
C) A random sample of 10 taken from a population distribution that is skewed to the right
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.In option C, there is an skewed variable and a sample size less than 30, hence, the Central Limit Theorem is not applicable.

21a-14b
15b-20a
Step-by-step explanation:
Answer: a + 3b
Step-by-step explanation:
Okay, so...
7(3a - 2b) = 7(3a) - 7(2b) ... distributive property
21a - 14b
5(3b - 4a) = 5(3b) - 5(4a) ... distributive property
15b - 20a
(21a - 14b) + (15b - 20a) = 21a -12b + 15b - 20a =

The angle of elevation from a park bench 724 feet from the base of the Gateway Arch in St. Louis, Missouri is 22°. How tall is the Gateway Arch, rounded to the nearest whole number?
Answer:
Gateway Arch is [tex]292.46[/tex] feet tall
Step-by-step explanation:
As we know,
the horizontal distance from the gate of the Arch to the bench [tex]= 724[/tex] feet
The angle of elevation is [tex]22[/tex] degree
Let H be the height of the gate be "H"
Tanθ= Perpendicular/Base
Substituting the given values in above equation, we get -
[tex]tan 22 = \frac{H}{724} \\H = 724 * tan 22\\H = 724 * 0.404\\H = 292.46[/tex]feet

circumference: 18.84 units
A>
circumference: 31.4 units

circumference: 37.68 units

Answer:
radius: 3 units <----> Circumference: 18.84 units
Diameter: 12 units <----> Circumference: 37.68 units
Diameter: 36 units <----> Circumference: 113.04 units
Radios: 5 unites <----> Circumference: 31.4 units
Step-by-step explanation:
How I got the answers for the radiuses:
3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)
3 x 2 = 6
C = pi x d
C = 3.14 x 6
C = 18.84 [this is the first radios]
5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)
5 x 2 = 10
C = pi x d
C = 3.14 x 10
C = 31.4 [this is the second radios]
How I got the diameters:
12 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 12
C = 37.68 [this is the first Diameter]
36 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 36
C = 113.04 [this is the second Diameter]

Here are five number cards 2, 5, 7, 8,9. One of the cards is removed and the mean average of the remaining four number cards is 6. Which card was removed you must show your working out
Answer:
7
Step-by-step explanation: Trust me
Answer:
Calculate the average of the five original cards:
2+5+7+8+9=31
31/5 = 6.2
So, if a card was removed, the four remaining cards would have an average of 6, meaning that they would add up to 24.
31-x=24?
Subtract 31 from both sides: -x=-7
Divide by -1 on both sides: x=7
So, we know that 7 was removed.

Answer:
14.4 centimeters
Step-by-step explanation:
The formula for circumference is: [tex]2\pi r[/tex]. In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x [tex]\pi[/tex] (pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.

An oblique cylinder has a radius of 16 meters and a volume of 5,120(pi) cubic meters. Use Cavalieri’s Principle to solve for the height of the solid.
20 meters
25 meters
50 meters
250 meters
Answer: 20 meters
Step-by-step explanation:
We are told that an oblique cylinder has a radius of 16 meters and a volume of 5,120 pi cubic meters. We will use volume of oblique cylinder to find the height of our given cylinder. volume of a oblique cylinder= πr²hUpon substituting our given values in above formula we will get,5,120π m³ = π ( 16 m² × h )
5,120π m³ = π × 256 m² × h
Let us divide both sides of our equation by 100 pi.Therefore, height of our given oblique cylinder is 20 meters.
