1,2,10,6,4,4,6,3,1,4 what is the median ?
Answer:
4
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
The median is the middle number in a set of numbers.
First what we need to do is put the numbers from least to greatest (ascending order).
1, 2, 10,6, 4, 4, 6, 3, 1, 4
1, 1, 2, 3, 4, 4, 4, 6, 6, 10
Now that we have ordered them, which one(s) is/are in the middle?
We have two numbers that share the middle. They are 4 and 4.
In cases where two numbers share the middle, we average them out. We do this by adding our two numbers together and then dividing by 2.
4 + 4 = 8
8 ÷ 2 = 4
Therefore our median is 4!
Tyra spent 4/5 of her money on gas for her car and 1/2 of the remainder on sandwiches. If she spent $9 on sandwiches, how much money did tyra have first
Answer:
The initial amount of money Tyra has is $90
Step-by-step explanation:
Let the initial money Tyra has be equal to y
She spent ⁴/₅ of her initial money on gas for her car = ⁴/₅ of y
She spent ¹/₂ of the remainder on sandwiches;
the remainder = 1 - ⁴/₅ = ¹/₅
¹/₂ of the remainder = ¹/₂ x ¹/₅ = ¹/₁₀
Thus, she spent ¹/₁₀ of her money on sandwiches = ¹/₁₀ of y
Amount she spent on sandwiches = $9 = ¹/₁₀ of y
[tex]\frac{y}{10} = \$ 9\\\\y = \$ 90[/tex]
Therefore, the initial amount of moneyTyra has is $90

Answer:
10x10x10
Step-by-step explanation:
Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000. When n is less than 0, the power of 10 is the number 1 n places after the decimal point; for example, 10−2 is written 0.01. if im not right i tried to fix the math question

The length of each side of the two congruent sides of an isosceles triangle is 2n + 7 and the length of the third side is 3n. Write two equivalent expressions for its length of the perimeter.
PLEASE HELPPPP
Answer:
7n + 14 and 7(n + 2)
Step-by-step explanation:
We know that since our triangle is isosceles, then two of the sides are the same. Given in the problem, we know that these two congruent sides are both 2n + 7. We also know the third side is 3n.
Perimeter is essentially just the sum of the side lengths of the figure. We simply need to add 2n + 7, 2n + 7, and 3n together:
P = 2n + 7 + 2n + 7 + 3n
Combine like terms:
2n + 2n + 3n + 7 + 7
7n + 14
That's one way we can write it. Another way is to factor out the 7:
7n + 14 = 7(7n/7 + 14/7) = 7(n + 2)
Thus, our two expressions are: 7n + 14 and 7(n + 2).

Carter took 7 coins out of his pocket. He did not have any pennies.He had more than $0.95 and less than $1.13 what could his coins have been ?Prove your anser
Answer:
Carter's coins could be;
3 of 5¢, 2 of 10¢, 1 of 25¢, and 1 of 50¢
Step-by-step explanation:
The available coin denominations are;
1¢ = 1 penny, 5¢, 10¢, 25¢, 50¢, and $1.00
Since the coins are more than $0.95, we can have;
5¢ × 3
10¢× 2
25¢× 1
50¢
Total = $1.00
That is his coins could have been 3 × 5¢, 2 × 10¢, 1 × 25¢, and 1 × 50¢, to make a total of 7 coins with an amount value of $1.00.
Find the lowest common denominator for the fractions shown.
8/51
19/85
a. 255
b. 17
c. 4,335
Answer:
A.
Step-by-step explanation:
Just find the lowest common multiple of 51 and 85.
51 = 3 * 17
85 = 5 * 17
3 * 5 * 17 = 255
The lowest common denominator for the fractions is 17.
What are Fractions?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
fraction = 8/51 and 19/ 85
Now, LCM of 51 and 85.
51 = 17 x 3
85= 17 x 5
So, the least common multiple is 17.
Hence, the lowest common denominator for the fractions is 17.

Answer:
The answer is [tex]s = - \frac{3}{2}[/tex] .

Theresa has a rectangular pool 30 ft long, 15 ft wide, and 4 ft deep. Theresa fills her pool using city water at a rate of $3.95 per 100 gallons of water.
Nancy has a circular pool with a diameter of 24 ft and a depth of 4 ft. Nancy fills her pool with a water delivery service at a rate of $200 per 6000 gallons.
If Theresa and Nancy both fill their pools 6 inches from the top of the pool, determine and state who paid more to fill her pool. [ 1 ft3 water = 7.48 gallons]
Answer:
Step-by-step explanation:
Both pools were filled 6 inches from the top.
12 inches = 1 feet
6 inches = 6/12 = 0.5 foot
Considering Theresa's pool, it is rectangular. The formula for determining the volume if the rectangular pool is
Volume = length × width × height
Height filled is 4 - 0.5 = 3.5 feet
Volume = 30 × 15 × 3.5 = 1575 ft³
Recall, 1 cubic feet = 7.48 Us gallons
Therefore,
1800 cubic feet = 1575 × 7.48 = 11781 gallons of water
Theresa fills her pool using city water at a rate of $3.95 per 100 gallons of water. It means that the amount she paid to fill her pool is
3.95 × 11781/100 = $465.35
Considering Nancy's pool, it is cylindrical. The formula for determining the volume if the cylindrical pool is
Volume = πr²h
Diameter = 24
Radius = diameter/2 = 24/2 = 12 ft
Volume = 3.14 × 12² × 3.5 = 1582.56 ft³. Converting to gallons, it becomes
1582.56 × 7.48 = 11837.55 gallons of water.
Nancy fills her pool with a water delivery service at a rate of $200 per 6000 gallons.
It means that the amount she paid to fill her pool is
200 × 11837.55/6000 = $394.59
Therefore, Theresa paid more to fill her pool.

The graph below shows three different normal distributions.
D) Each distribution has the same mean and a different standard deviation.
What is standard deviation and mean?The spread in the provided normal curves exists due to various standard deviations. The mean for all three curves lies at the center of the curve.
Therefore, each distribution contains the same mean and a separate standard deviation.
Therefore, the correct answer is option (D) "Each distribution has the same mean and a different standard deviation."

A mirror should be centered on a wall the mirror is 4 feet wide in the wall is 20 Feet wide what equation helps determine the distance X on each side of the mirror
Answer:
A)x + 4 + x = 20
Step-by-step explanation:
Complete question:
Which equation helps determine the distance x on each side of the mirror?
A. x + 4 + x = 20
B. 4 + x + 4 = 20
C. x = 20 + 4 + 4
D. 4 = 20 + x + x
SOLUTION:
As given,The mirror is 4 feet wide and the wall is 20 feet wide.
The distance 'x' on each side of the mirror is x + x
4 feet wide + x + x = 20 feet wide
The mirror 4 feet wide + the distance x on each side of the mirror = the wall is 20 feet wide
Therefore, the correct option is A

The zoo also has a merry go round. To set up the merry go round, the zoo manager has to clear some land. The diameter of the merry go round is 18 feet. How much land does the manager need to clear in order to build the merry go round?
Answer:
254.34 m^2
Step-by-step explanation:
To know the amount of land that needs to be cleared, we must calculate the area that this land would occupy.
We know that the area would be determined by:
A = pi * r ^ 2
the radius is half the diameter:
r = d / 2 = 18/2
r = 9
the radius equals 9 feet, replacing:
A = 3.14 * 9 ^ 2
A = 254.34
Therefore, an equivalent amount of land 254.34 square meters would have to be cleared so that it can be built
