Which Linear Equation represents the data given in the table A) y= 3x+8 B). Y=8X+3 C). Y=3X-8 D) 8X-3
Snezhnost [94]
<h2>Explanation:</h2><h2></h2>

Hello! remember that you have to write complete questions in order to get good and exact answers. Here you haven't provided any table so I'll assume a table, which is shown below:

\begin{array}{cc}x & y\\0 & 8\\1 & 11\\2 & 14\\3 & 17\\4 & 20\end{array}

Remember that the slope intercept form of the equation of a line is given by:

y=mx+b

Where:

m:slope \\ \\ b:y-intercept

The y-intercept occurs when x=0, thus from the table:

b=8

And the slope can be found as:

m=\frac{y_{2-y_{1}}}{x_{2}-x_{1}} \\ \\ m=\frac{11-8}{1-0}=3

Therefore, the equation that represents the table is:

y=3x+8

Correct option:

A)

Let A= the sky is red at night
let B= the weather will be nice the next day

Since this is based on Conditional Probability,

P(B|A)
This is read: The probability that the weather iss nice the next day GIVEN the sky is red at night.

Answer:

The surface area of the prism is 1,664\ mm^{2}

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to

SA=2B+PL

where

B is the area of the triangular face

P is the perimeter of the triangular face

L is the length of the triangular prism

<em>Find the area of the triangular face B</em>

B=\frac{1}{2}(24)(16)= 192\ mm^{2}

<em>Find the perimeter of the triangular face P</em>

P=(24+20+20)= 64\ mm

we have

L=20\ mm

substitute the values

SA=2(192)+(64)(20)=1,664\ mm^{2}

What is the real part of the following complex number?<br> -3+ 2iV2
Marina86 [1]

Answer:

Option (3)

Step-by-step explanation:

If a complex number is in the form of (a + ib), real part of the complex number is 'a' and imaginary part is 'b'.

Given complex number is (-3 + 2i )

Comparing this number with (a + ib), real part of the number will be (-3) and imaginary part of the number will be 2.

Option (3) will be the answer.

In ΔNOP,the measure of ∠P=90°, NP = 16, ON = 65, and PO = 63. What ratio represents the cosecant of ∠N?
Grace [21]

Answer: 65/63

Step-by-step explanation:

The cosecant of angle N is the reciprocal of the sine of angle N.

Using SOHCAHTOA, the sine of angle N is 63/65.

This means that the cosecant of angle N is 65/63.
