Total number of blue candies = 20 + 30 = 50
Number of blue candies without nut = 20

Probability of picking a blue candy without a nut = (Number of blue candies with nut) /(Total number of blue candies)

So, Probability of picking a blue candy without a nut = $\frac{20}{50} =0.4=40$ %

Thus, the correct answer is option A

What is the slope-intercept form of the function described by this table? X 1 2 3 4 y 8 13 18 23 Enter your answer by filling in

taurus [48]

Answer:

The slope-intercept form of the function is:

$y=5x+3$

Step-by-step explanation:

Given the table

x y

1 8

2 13

3 18

4 23

Let us take two points (1, 8) and (2, 13) to find the slope

(1, 8)

(2, 13)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(1,\:8\right),\:\left(x_2,\:y_2\right)=\left(2,\:13\right)$

$m=\frac{13-8}{2-1}$

$m=5$

We know that the slope-intercept form of the line equation is

$y=mx+b$

where m is the slope and b is the y-intercept.

substituting the values m=5 and the point (1, 8) to determine the y-intercept i.e. 'b'.

$y=mx+b$

8 = 5(1) + b

b = 8-5

$b = 3$

Now, substituting the values m=5 and b=3 in the slope-intercept form to

$y=mx+b$

$y=5x+3$

Thus, the slope-intercept form of the function is:

$y=5x+3$

Estimate 31,969 divided by 488

Alekssandra [29.7K]

Hi there! ~

So by "diving" we are just going to use the symbol of;

/

So now, 31969 / 488

= 65.5102459016

And, because we are estimating, you could say = 66. (When rounding) or simply 65.51

Average Rate of Change: $\displaystyle \displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1; Define

Identify

f(x) = 5ˣ + 1

Interval x [0, 4] →b = 4, a = 0

Step 2: Find Rate of Change

Substitute in variables [Average Rate of Change]: $\displaystyle \displaystyle \frac{f(4) - f(0)}{4 - 0}$
[Average Rate of Change] Substitute in x [Function f(x)]: $\displaystyle \displaystyle \frac{(5^4 + 1) - (5^0 + 1)}{4 - 0}$
(Parenthesis) Evaluate exponents: $\displaystyle \displaystyle \frac{(625 + 1) - (1 + 1)}{4 - 0}$
(Parenthesis) Add: $\displaystyle \displaystyle \frac{626 - 2}{4 - 0}$
[Fraction] Subtract: $\displaystyle \displaystyle \frac{624}{4}$
Divide: $\displaystyle \displaystyle 156$
