Klio2033 [76]

Answer:

G

Step-by-step explanation:

Since there are 50 students being asked, to find a percentage, put the output (the number of students that chose each genre) and the input (the number of students asked all together) in ratio form as a fraction. You will get the fractions 10/50, 16/50, 20/50, and 4/50. Multiply each denominator by two to get the percentage. You will get 20/100, 32,/100, 40/100, and 8/100. If you look at the four answers provided, you can cross out J immediately because it shows that "Other" was the greatest percentage, when it is in fact the smallest. H can be crossed out as well, since the percentage for "Mystery" is over 20% when it should be exactly at 20%. F can be crossed out as well because it shows that "Other" takes up 10%, when it is actually a bit less, 8%. G is the best choice because the percentage that "Other" takes up is a bit less than 10%, so it's safe to say that it shows 8%.

The first term of an arithmetic sequence is equal to four and the common difference is three. find the formula for the value of

hichkok12 [17]

The formula for the value of nth term is $a_{n}$ = 3n + 1

Step-by-step explanation:

The formula of the nth term in the arithmetic sequence is

$a_{n}=a+(n-1)d$ , where

a is the first term of the sequence
d is the common difference between each two consecutive terms

∵ The first term of an arithmetic sequence is equal to four

∴ a = 4

∵ The common difference is equal to three

∴ d = 3

- Substitute these values in the rule of the nth term

∵ $a_{n}=a+(n-1)d$

∴ $a_{n}=4+(n-1)3$

- Simplify it

∴ $a_{n}=4+3n-3$

∴ $a_{n}=1+3n$

The formula for the value of nth term is $a_{n}$ = 3n + 1

Please help! Find the equation of the line (graph provided in attached picture) Use exact numbers. y =_ x+_ ( _ represent blanks

Dennis_Churaev [7]

Answer:

$y = \frac{3}{4}x - 2$

Step-by-step explanation:

Equation of a line is given as $y = mx + b$

Where,

m = slope of the line = $\frac{y_2 - y_1}{x_2 - x_1}$

b = y-intercept, which is the value at the point where the line intercepts the y-axis. At this point, x = 0.

Let's find m and b to derive the equation for the line.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Use the coordinate pair of any two points on the line. Let's use the following,

$(0, -2) = (x_1, y_1)$ => on the line, when x = 0, y = -2

$(4, 1) = (x_2, y_2)$ => on the line, when x = 4, y = 1

Plug in the values and solve for m

$m = \frac{1 - (-2)}{4 - 0}$

$m = \frac{1 + 2}{4}$

$m = \frac{3}{4}$

b = -2 (the line intercepts the y-axis at this point)

Our equation would be =>

$y = mx + b$

$y = \frac{3}{4}x + (-2)$

$y = \frac{3}{4}x - 2$

The rule for this number sequence is (n+3) x 2

zzz [600]

6 + 12 = 18
18 + 24 = 42
Double the difference between every 2 numbers (12 x 2 = 24 x 2 = 8)
42 + 48 = 90
90 is the missing number
Happy to Help!
