Write an equation of the line below.
Lubov Fominskaja [6]

Answer (<u>assuming it can be in slope-intercept form)</u>:

y = \frac{4}{5} x

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula m = \frac{y_2-y_1 }{x_2-x_1} and substitute the x and y values of two points on the line into it. We can see that the line passes through (0,0) and (5,4), so let's use those points for the formula and solve:

m = \frac{4-0}{5-0} \\m = \frac{4}{5}

So, the slope is \frac{4}{5}.

2) Next, identify the y-intercept of the line. The y-intercept is the point at which the line intersects the y-axis. We can see that the line intersects the y-axis at (0,0), so that must be the y-intercept.

3) Now, write the equation of the line in slope-intercept form using the y = mx + b format. The number in place of m represents the slope, so substitute \frac{4}{5} in its place. The number in place of b represents the y-intercept, so substitute 0 in its place. This gives the following answer and equation:

y =\frac{4}{5} x+0\\y = \frac{4}{5} x

A certain stock exchange designates each stock with a one-, two-, or three-letter code, where each letter is selected from the 2
Sophie [7]

Answer: Option 'e' is correct.

Step-by-step explanation:

Since we have given that

Number of letters of the alphabet = 26

Number of letters in code :

One letter code, or two letter code, or three - letter code.

Since repetition of letters are allowed, then

if it is one letter code, the number of arrangement would be 26.

If it is two letter code, the number of arrangements would be

26\times 26\\\\=26^2\\\\=676

If it is three letter code, the number of arrangements would be

26\times 26\times 26\\\\=26^3\\\\=17576

So, Number of different stocks to uniquely designate with these codes would be

26+676+17576\\\\=18278

Hence, Option 'e' is correct.

The triplets, nick, Brian, and dan, exit their preschool classroom every day in a random order. Create an organized list to show
AfilCa [17]

The set of all possibilities is called sample space and is denoted by S.

So, S = {NBD, NDB, BDN, BND, DBN, DNB} and n(S) = 8

and we need to find the probability of NBD

E = {NBD} and n(E) = 1

The probability of an even is defined by p(E) = \frac{n(E)}{n(S)}

Hence,  p(E) = \frac{1}{8}
