What is the slope of the line represented by the equation y = y equals StartFraction 4 Over 5 EndFraction x minus 3.x – 3?

lisov135 [29]

Answer:

The slope of the line $y=\frac{4}{5}x-3$ is $\frac{4}{5}$

Step-by-step explanation:

The given equation can be written as

$y=\frac{4}{5}x-3\hfill (1)$ represents a line equation.

The general equation of the straight line is $y=mx+c\hfill (2)$

where m is the slope and c is intercept

Comparing equations (1) and (2) we get slope $m=\frac{4}{5}$

Therefore slope of the line $y=\frac{4}{5}x-3$ is $\frac{4}{5}$

the letters that spell Mississippi are each written on separate tiles lying face down on a table. a tile is selected at random,

Mars2501 [29]

Answer: The theoretical probability of choosing a tile with letter P =0.18

Step-by-step explanation:

Given word = MISSISSIPPI

Total number of letters in given the word = 11

Number of letter P in given word = 2

Let A be a event of choosing a tile with a letter P then

P(A) =Number of tiles with letter P / Total letters in given word

= 2 /11 = 0.18

- In the following diagram of triangle QRS, QR = 8 and QS = 17. Determine the value of sin Q. Show how you

dimaraw [331]

Answer:

$SinQ=\frac{15}{17}$

Step-by-step explanation:

We draw the right triangle as shown in the image attached.

Δ QRS

Where R is the right angle

Given

QR = 8

QS = 17

Now, using Pythagorean Theorem, we can find RS:

$QR^2+RS^2=QS^2\\8^2+RS^2=17^2\\RS^2=17^2-8^2\\RS^2=225\\RS=\sqrt{225}\\RS=15$

Now, we know the ratio Sine as:

$Sin(\theta)=\frac{Opposite}{Hyotenuse}$

Where $\theta$ is the angle (here angle Q)

Opposite side is RS (which is 15)

Hypotenuse is given as QS (which is 17)

So,

$SinQ=\frac{15}{17}$

This is the value of SinQ.

We don't want the angle, so we'll stop here.
