Answer:

y= $\frac{3}{4}\\$ x-1

Step-by-step explanation:

The slope intercept form is in y=mx+b. Therefore you plug in the following:

- slope = m

- y-intercept = b

Since the problem gives both of these informations you just have to plug it in.

What is the slope of the line represented by the equation y-6=5(x-2)

Nookie1986 [14]

<span>y - 6 = 5(x - 2)

As you know y - y1 = m(x - x1) where m = slope

in this case </span>y- 6 = 5(x - 2), m = 5

Answer: Slope m = 5

the length of a rectangle is 5 more than twice its width. its perimeter is 88 feet. find its dimensions

podryga [215]

Length = x; width = y
2x+2y=88
x=2y+5
4y+10+2y=88
6y=78
y=13 feet
x=26+5
x=31 feet

Question 12 (1 point) Given P(A) 0.34, P(A and B) 0.27, P(A or B) 0.44, what is P(B)? Answer in decimal form. Round to 2 decimal

Tema [17]

Answer: The required probability of event B is P(B) = 0.37.

Step-by-step explanation: For two events A and B, we are given the following probabilities :

P(A) = 0.34, P(A ∩ B) = 0.27 and P(A ∪ B) = 0.44.

We are to find the probability of event B, P(B) = ?

From the laws of probability, we have

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\\Rightarrow 0.44=0.34+P(B)-0.27\\\\\Rightarrow 0.44=0.07+P(B)\\\\\Rightarrow P(B)=0.44-0.07\\\\\Rightarrow P(B)=0.37.$

Thus, the required probability of event B is P(B) = 0.37.
