Which table represents a linear function? y=3,7,11,15 y=3,8,15,21 y=3,9,3,9 y=3,9,27,81?

steposvetlana [31]

The table that represents a linear function is y=3,7,11,15

<h3>How to determine the table?</h3>

For a table to represent a linear function, the table must have a constant rate of change i.e. a common difference

From the list of options, we have:

y=3,7,11,15

The difference between each y value is 4

i.e. 7 - 3 = 11 - 7 = 15 - 11 = 4

Hence, the table that represents a linear function is y=3,7,11,15

Find the value of x, which makes the area of this triangle equal 72.

Ghella [55]

Area of a triangle=1/2(base x height)
Area=72, Base=8, Height=2x-3
Plug it in.
72=1/2(8 x (2x-3))
72=1/2(16x-24)
72=8x-12
84=8x
x=10.5

Which sentence correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14

denis-greek [22]

Answer:

Option (c) is correct.

68% of the data points lie between 10 and 18.

Step-by-step explanation:

Given : a normal distribution with a standard deviation of 4 and a mean of 14

We have to choose the sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.

Since, given 68% data.

We know mean of data lies in middle.

And standard deviation is distribute equally about the mean that is 50% of values less than the mean and 50% greater than the mean.

So, 68% of data lies

mean - standard deviation = 14 - 4 = 10

mean + standard deviation = 14 + 4 = 18

So, 68% of the data points lie between 10 and 18.

the length of a rectangle is 5 inches longer than twice the width and the area is 12 inches squared. Let l represent the length

svet-max [94.6K]

Answer:

Length = 8 inch , Width = $\frac{3}{2}$ , This equation models the situation

Step-by-step explanation:

Given as ;

The Area of Rectangle is 12 inches²

The Length of Rectangle is 5 inches longer than twice the width

Let The Length = L inches

The Width = W inches

According to question ,

L = 5 + (2 × w )

∵ The Area of Rectangle = Length × width

Or, 12 inches² = [ 5 + (2 × w ) ] × w

Or, 12 inches² = 5 w +2 w²

Or, 2 w² + 5 w - 12 = 0

Or, 2 w² + 8 w -3 w - 12 = 0

Or, 2 w (w +4) - 3 (w + 4) = 0

I.e (w + 4) ( 2 w - 3) = 0

So , w = -4 , and w = $\frac{3}{2}$

∴ Length = 5 + (2 × w ) =

Length = 5 + (2 × $\frac{3}{2}$ )

so , L = 5 + 3 = 8

Hence Length = 8 inch , Width = $\frac{3}{2}$ This equation models the situation Answer
