The probability of an event is notated P(event) in mathematics.
So if event A has a probability of 0.73, notationwise we say P(A)=0.73

Answer: Option '' a " is correct.

Step-by-step explanation:

Since we have given that

the probability of an event A occurring is 0.73

that means A is an event.

and the chances of getting an event A is written by P(A).

So, it becomes,

Probability of getting an event A is given by

$P(A)=0.73$

Hence, Option '' a " is correct.

How do you get the fully simplified slope-intercept form?

Mnenie [13.5K]

Answer:

y = 3x - 7

Step-by-step explanation:

Slope-intercept form:

y = mx + b

Where:

y is the y value.

m is the slope.

x is the x value.

And b is the y-intercept.

First, you want to find your slope. To do this, you can either use the slope formula to find the slope, or just count on the picture:

m = rise/run

m = 3/1

m = 3

With the slope formula, you first need to choose two points.

I chose:

(2, -1) and (3, 2)

Slope formula:

m = (y2 - y1) / (x2 - x1) {It doesn't matter which point you choose to be x2 and x1, just be consistent when you plug it into the formula}

m = (2 - (-1)) / (3 - 2)

m = 3/1

m = 3

Now that you have your slope, all you need is your y-intercept. To find your y-intercept, you can either look at the graph (again) to see where the line intersects with the y-axis, or you can solve it algebraically:

y-int = -7

To solve algebraically, choose a random point on the line and plug it into what you have for your equation so far and then solve for b.

I chose:

(2, -1)

y = 3x + b

-1 = 3(2) + b

-1 = 6 + b

-1 - 6 = b

b = -7

Now you have your final answer:

y = 3x - 7

Simple the expression ( 3k + 4 1/5) + 8 3/5

lesantik [10]

Answer:

$3k+12\frac{4}{5}$

Step-by-step explanation:

$(3k+12\frac{4}{5})$

Convert mixed numbers to improper fractions:

$a\frac{b}{c}=\frac{a*c+b}{c}$

$4\frac{1}{5}=\frac{4*5+1}{5}$

$=\frac{21}{5}$

$=(3k+\frac{21}{5} )+\frac{43}{5}$

Add the fractions

$\frac{21}{5}+\frac{43}{5}$

$\frac{21}{5} \frac{43}{5} =\frac{64}{5}$

$=3k+\frac{64}{5}$

Divide 64 by 5

$\frac{64}{5}$ $12.8 or 12\frac{4}{5}$

$=3k+12\frac{4}{5}$

Troy cut a 100 foot rope into 3 pieces. The first piece is 43 foot long. The second piece is at least 22 feet long, but no great

Inessa05 [86]

Answer:

x=4

Step-by-step explanation:

Let he first piece be x the second be 3x and the very last one be 7x + 2

Add all the pieces together and you ought to get the length of the rope which is 46 ft

So your equation would be

x + 3x + 7x + 2 = 46

11x = 44

x = 44 / 11

x = 4

so the 3 pieces are 4 , 12 and 30ft

Limits of a Function

Novay_Z [31]

We are given the equation:

$\lim_{x \to 1} \frac{f(x)-8}{x-1} = 10$

which can be rewritten as:

$\frac{\lim_{x \to 1}[f(x)-8]}{\lim_{x \to 1}[x-1]} = 10$

$\lim_{x \to 1}[f(x)-8] = 10*\lim_{x \to 1}[x-1]$

$\lim_{x \to 1}[f(x)-8] = \lim_{x \to 1}[10x-10]$

which means that..

$f(x) - 8 = 10x - 10$

$f(x) = 10x - 10 + 8$

$f(x) = 10x - 2$

Finding the limit:

 $\lim_{x \to 1} f(x) = \lim_{x \to 1} (10x - 2)$ 

 $\lim_{x \to 1} f(x) = 10(1) - 2$ 

 $\lim_{x \to 1} f(x) = 8$
