Enter the number that belongs in the green box.

ale4655 [162]

Answer:

the green box is 0

Step-by-step explanation:

we are asked to find the <u>x-intercept</u>, which means y = 0

(x, y)

Another way to test this is plug it in 1 for x! (1, y) where x = 1

$y = \frac{2x^{2} -3x+1}{2x^{2} +8x+6} \\\\$

$y = \frac{2(1)^{2} -3(1)+1}{2(1)^{2} +8(1)+6}$

$y = \frac{2(1) -3(1)+1}{2(1) +8+6}$

$y = \frac{2 - 3 + 1}{2 + 8 + 6}$

$y = \frac{-1+1}{10 + 6}$

$y = \frac{0}{16}$

y = 0

What is the standard form of the following equation y + 3 = 1/4x Use integers for A,B, and C.

Nezavi [6.7K]

Answer:1/4x+y=-3

Step-by-step explanation:

You have to move 1/4x to the left side by adding the inverse of 1/4x, -1/4x to each side. Then you have 1/4x+y+3=3. After this you have to use the subtraction property of equality. Then your answer is 1/4x+y=-3

Assume that a procedure yields a binomial distribution with a trial repeated nequals30 times. Use the binomial probability formu

Irina-Kira [14]

Answer:

$P(X = 5) = C_{30,5}.(0.2)^{5}.(0.8)^{25} = 0.172$

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}[\tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.[tex]C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this problem, we have that:

$n = 30, p = \frac{1}{5} = 0.2$

Use the binomial probability formula to find the probability of xequals5 successes given the probability pequalsone fifth of success on a single trial.

This is P(X = 5).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 5) = C_{30,5}.(0.2)^{5}.(0.8)^{25} = 0.172$
