If Melissa estimates she would read 250 but she read 290 what is the percent error

Answer:

The Median is 9

Step-by-step explanation:

To calculate the median of a data set the first step is to sort the data from least to greatest

4,11,6,9,23,34,6,9

4, 6, 6, 9, 9, 11, 23, 34

The second step is to locate the central value. If the total amount of data is an even number then locate the two central data and the median will be the average of both. In this case we have 8 data. Then the central values will be the data number 4 and the data number 5

4, 6, 6,   [9, 9],   11, 23, 34

[tex]Median = \frac{9+9}{2}=9[/tex]

IN the given figure.

angle A + angle B + angle C = 180°

( angle sum property of Δ)

58°+47°+ x = 180°

105°+ x =180°

x = 180° - 105°

thus correct option is (d)

hope this will help u!!

For this case we must find the value of the variable "x" of the following equation:

[tex]\frac {2} {3} (x + 7) = 10[/tex]

We multiply by 3 on both sides of the equation:

[tex]2 (x + 7) = 30[/tex]

We divide between 2 on both sides of the equation:

[tex](x + 7) = 15\\x + 7 = 15[/tex]

We subtract 7 on both sides of the equation:

[tex]x = 8[/tex]

Option B

Answer:

Z is also 116*

Step-by-step explanation:

The reason for them being the same is because of something called alternating angles. This process allows you to find two angle measurements by just finding one.

Answer:

144*pi cm^2

Step-by-step explanation:

The formula for the surface area of a sphere is A = 4*pi*r^2.

If the diameter is 12 cm, the radius, r, is 6 cm.

Thus, in this case, the surface area of the sphere is

A = 4*pi*(6 cm)^2 = 144*pi cm^2.

Answer:

Surface area = 452 square cm.

Step-by-step explanation:

surface area of a sphere with a diameter 12 cm

Diameter = 12 cm

Radius = diameter divide by 2=  [tex]\frac{12}{2} =6[/tex]

Surface area of a sphere = [tex]4\pi r^2[/tex]

Where 'r' represents the radius of the sphere

[tex]4\cdot \pi \cdot 6 \cdot 6= 452.3893421[/tex]

Now round the answer to nearest whole number

Surface area = 452 square cm.

Answer:

-8x + 6

Step-by-step explanation:

Subtract "5x-2" from "-3x + 4". Set the equation.

(-3x + 4) - (5x - 2) = Answer (A)

First, distribute -1 to all terms within the second parenthesis.

-3x + 4 - 5x + 2 = A

A = -5x - 3x + 4 + 2

Simplify. Combine like terms (terms with the same amount of variables).

A = (-5x - 3x) + (4 + 2)

A = -8x + 6

-8x + 6 is your answer, or the first answer choice.

Answer:

8/20 red marbles

6/20 yellow marbles

6/20 green marbles

Step-by-step explanation:

All of them added together is 20 and there is a probability of choosing 8 red marbles, 6 green marbles, and 6 yellow marbles?

Answer:

[tex]\frac{4}{95}[/tex]

Step-by-step explanation:

Total number of marbles in the bag = [ 6 green + 8 red + 6 yellow ] = 20

Then probability of choosing red marble = 8/20

total number of remaining marbles = 19

Then probability of choosing yellow marble = 6/19

total number of remaining marbles = 18

Then probability of choosing green marble = 6/18

Hence required probability that you choose a red marble, followed by a yellow marble, followed by a green marble [tex]=\frac{8}{20}\cdot\frac{6}{19}\cdot\frac{6}{18}[/tex]

[tex]=\frac{4}{95}[/tex]

Hence final answer is [tex]\frac{4}{95}[/tex]

Answer: 5.5

Step-by-step explanation: Converting This To A Decimal Would Be 5.5

to make it into a decimal you would convert the fraction into a decimal which would be .5 then you would take the 5 and make it 5.5

For this case we have the following mixed number:

[tex]5 \frac {1} {2}[/tex]

We move to fraction, then we have to:

[tex]5 \frac {1} {2} = \frac {5 * 2 + 1 * 1} {2} = \frac {10 + 1} {2} = \frac {11} {2}[/tex]

Dividing we have to:

[tex]\frac {11} {2} = 5.5[/tex]

Answer:

[tex]5 \frac {1} {2} = 5.5[/tex]

The answer is C.

5+0=x

we have

[tex]b=14\ cm[/tex] ----> the length of the base of the square pyramid

[tex]h=11\ cm[/tex] ---> the height of the pyramid

substitute the values in the formula

To calculate the arc length of a circle with a 120° central angle and a 9-unit radius, multiply the fraction of the circle (1/3) by the circle's circumference (2πr) to find the arc length is 6π units.

To find the length of an arc with a central angle of 120° in a circle with a radius of 9, we use the formula for arc length. The arc length (As) is proportional to the angle of rotation, which in this case is 120° or θ = 120° ÷ 360°.

The circumference (C) of a circle is given by the formula 2πr, where r is the radius. For a full revolution (360°), the arc length is equal to the circumference. For an angle θ, the arc length is given by:

As = (θ/360°) × 2πr

Using the radius r = 9 and θ = 120°, we calculate:

As = (120°/360°) × 2π(9)

As = (1/3) × 18π

As = 6π

The arc length is 6π units, which is slightly less than 19, as π is approximately 3.14159.

Answer:

First Option

Step-by-step explanation:

A relation is an association or correspondence between two sets, where each element of the Domain Set corresponds to at least one element of the Range set.

The function definition says that:

A relation is a function if and only if, for each input value x, there is only one output value y. In other words, a relation is a function if each value of the Domain set has only one value associated with the Range set.

Therefore, not all relationships are functions, but all functions are relations.

The correct option is the first

Answer:

11,232,000

Step-by-step explanation:

The key to this problem is knowing "repetition is NOT ALLOWED".

For the first 3 letters slot:

For the 1st slot, we can pick any of the 26 alphabets

For the 2nd slot, we can pick any of the 25 remaining alphabets (since 1 is already taken)

For the 3rd slot, we can pick any of the 24 remaining letters (since 2 is already taken)

For the three digits slot:

For the 1st slot, we can pick any one of the 10 digits

For the 2nd slot, we can pick any one of the 9 digits left, since 1 is taken already

For the 3rd slot, we can pick any one of the 8 digits left, since 2 is already taken

The number of license plates, thus, would be all of these multiplied together:

26 * 25 * 24 * 10 * 9 * 8 = 11,232,000

Answer:

D

Step-by-step explanation:

1. Use property of exponents:

[tex](a^b)^c=a^b\cdot ... \cdot a^b\ [\text{ take }c \text{ times } a^b][/tex]

Hence

[tex](7^{\frac{1}{3}})^3=7^{\frac{1}{3}}\cdot 7^{\frac{1}{3}}\cdot 7^{\frac{1}{3}}[/tex]

2. Use multiplication property of exponents:

[tex]a^b\cdot a^c=a^{b+c}[/tex]

Thus,

[tex]7^{\frac{1}{3}}\cdot 7^{\frac{1}{3}}\cdot 7^{\frac{1}{3}}=7^{\frac{1}{3}+\frac{1}{3}+\frac{1}{3}}[/tex]

3. Since

[tex]\frac{1}{3}+\frac{1}{3}+\frac{1}{3}=\frac{3}{3}=1,[/tex]

we have that

[tex]7^{\frac{1}{3}+\frac{1}{3}+\frac{1}{3}}=7^1=7[/tex]

Answer:

Step-by-step explanation:

Depending on the state and country, cars can have 1 or 2 license plates on them.  The one mandatory is in the back.  In some places, the cars also have a license plate in the front of the car.

So, since the answer is either 1 or 2, the range for that answer is under 10... so it's a single digit... making it a measure in ones.

The number of tires on a car is also measured in ones.  

____________________________________________________

Answer:

Your answer would be a 9.5% increase.

____________________________________________________

Step-by-step explanation:

In order to find the answer to your question, we would need to get the amount it's changing by, divide it by it's original, and multiply it by 100.

Your equation should look like this:

[tex]Change/Original * 100[/tex]

Important information in the question:

105 pounds

115 pounds (increase in amount of food that bear eats)

With the information above,we can plug those numbers into our equation.

Since we need to find the change, we would subtract 115 and 105 to get 10. 10 is our change in this scenario.

Our original started at 105, so that'll be our original in our equation.

When you plug in the information, your equation should look like this:

[tex]10/105*100[/tex]

Now you solve:

[tex]10/105*100\\\\0.0952 * 100\\\\=9.523[/tex]

We have to round to the nearest tenth, and the tenth place is the number right after the decimal place.

Since 2 is not a big enough number to round the 5, we would keep the number as 5. Therefore, your answer would be 9.5

Your FINAL answer would be 9.5%
