Answer:

Y-Int = -12

Step-by-step explanation:

First, I would change the equation to slope intercept form:

-3y = 36 + 4x

3y = -36 - 4x

y = -12-4/3x

y = -4/3x - 12

Simplifying

-4x + -3y = 36

Solving

-4x + -3y = 36

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

-4x + -3y + 3y = 36 + 3y

Combine like terms: -3y + 3y = 0

-4x + 0 = 36 + 3y

-4x = 36 + 3y

Divide each side by '-4'.

x = -9 + -0.75y

Simplifying

x = -9 + -0.75y

Translate the sentence into an inequality. The sum of 3 and c is less than -29.

Solnce55 [7]

Answer:

3+c < -29 or c+3 < -29 because of communitive property

Step-by-step explanation:

First, the sum means addition, you could write 3+c or c+3 because addition is communitive property.

Then the sum is less than -29 so we need to use the less than symbol which is this symbol: <

Now write the inequality! 3+c < -29

wariber [46]

Answer:

$P(x < 5)=P(X=0)+P(X=1)+P(X=2)+P(x=3)+P(X=4)$

$P(X=0)=(15C0)(0.5)^0 (1-0.5)^{15-0}=0.0000305$

$P(X=1)=(15C1)(0.5)^1 (1-0.5)^{15-1}=0.000458$

$P(X=2)=(15C2)(0.5)^2 (1-0.5)^{15-2}=0.0032$

$P(X=3)=(15C3)(0.5)^3 (1-0.5)^{15-3}=0.0139$

$P(X=4)=(15C4)(0.5)^4 (1-0.5)^{15-4}=0.0417$

And adding we got:

$P(x < 5)=0.0592$

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=15, p=0.5)$
