Answer:

Option (d) is correct.

for complete expression "eight times the difference of a number and three is sixty-four" is written as 8 ( N-3 )= 64

Step-by-step explanation:

Given expression "eight times the difference of a number and three is sixty-four"

We have to write it mathematically.

Consider the given expression "eight times the difference of a number and three is sixty-four"

Mathematically written as ,

Let the number be N,

the difference of a number and three is written as N - 3

eight times the difference of a number and three is written as 8( N - 3 )

Thus, for complete expression "eight times the difference of a number and three is sixty-four" is written as 8 ( N-3 )= 64

Thus, Option (d) is correct.

Answer:

1. is True

2. is true

Step-by-step explanation:

1. the reason they are both true is that they are all part of the quadrilaterals and because the 4 sides in each shape, but a trapezoid has one pair of parallel sides. Which makes both sentences true! Hope it helps :)

Whats the median number mode and mean for 95, 97, 100, 86, 78, 96

Naya [18.7K]

Answer:

Mean = 92

Median = 95.5

There is no mode.

What is mean, median, and mode?

Mean, median, and mode are terms in math when it comes to looking at charts and sets/groups of numbers.

1. The mean is the average of a data set.

2. The median is the middle of a data set.

3. The mode is the most common number in a data set.

Mean is found by adding the numbers and dividing the sum by the number of numbers in the list. This is what is most often meant by an average. The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list.

Before we start, let's put the set of numbers in order from least to greatest,

95, 97, 100, 86, 78, 96

78, 86, 95, 96, 97, 100

Now that we have done that let's find the mean,

78 + 86 + 95 + 96 + 97 + 100 = 552

There are 6 numbers in this set so we need to divide 552 by 6,

552 ÷ 6 = 92

92 is the mean/average of this data set,

Now let's find the median,

If we take a look at the data set we can see that there are two numbers in the middle because there are 6 in total,

78, 86, 95, 96, 97, 100

Because there are two values that are in the middle we need to add them up and divide the sum of them by 2,

95 + 96 = 191

191 ÷ 2 = 95.5

95.5 is the median of this data set,

Now let's find the mode,

If we take a look at the date set we can see that none of the numbers are repeated,

So this means there is no mode to this data set,

Therefore the mean is 92, the median is 95.5, and there is no mode.

Question 9 Multiple Choice Worth 1 points)

beks73 [17]

Answer: $\bold{10 = \sqrt {\left( {x- 8 } \right)^2 + \left( {y - 9 } \right)^2 }}$

Step-by-step explanation:

<u>Given:</u>

The coordinates of Point A: (8, 9)

The coordinates of Point B are unknown: (x, y)

The distance from A to B is 10 units

Then, using the distance formula:

$AB = \sqrt {\left( {x- 8 } \right)^2 + \left( {y - 9 } \right)^2 }$

Therefore,

$10 = \sqrt {\left( {x- 8 } \right)^2 + \left( {y - 9 } \right)^2 }$

How do i graph 2.5x+8y=200

julia-pushkina [17]

Answer:

Step-by-step explanation:

2.5x+8y=200

We want to get this in slope intercept form so we will solve for y

Subtract 2.5x from each side

2.5x-2.5x+8y=-2.5x +200

8y = -2.5x +200

Now divide by 8 on both sides

8y/8 = -2.5x/8 + 200/8

y = -.3125x +25

The y intercept is 25, so plot a point there

-.3125 = -5/16

Go down 5 and to the right 16 and plot a point. Connect the two points to make a line.
