80 divided by (6 + (3 - 5) X 2)

a_sh-v [17]

Answer:

40

Step-by-step explanation:

remember PEMDAS

our equation looks like tihs: $\frac{80}{(6+(3-5)*2)}$

1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.

so now our equation looks liek this $\frac{80}{(6-2 *2)}$

now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this: $\frac{80}{(6-4)}$

6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.

What is the y intercept of the graph of 4x + 2y = 12

yan [13]

Answer:

the y intercept is 6

Step-by-step explanation:

Step 1: Add -4x to both sides.

4x+2y+−4x=12+−4x

2y=−4x+12

Step 2: Divide both sides by 2.

2y /2 = −4x+12 /2

y=−2x+6

Points (3,6)

x intercept is 3 and y intercept is 6

For a continuous random variable x, the probability density function f(x) represents

jarptica [38.1K]

Answer:

Option d.

Step-by-step explanation:

we know that

The graph of a continuous probability distribution is a curve. Probability is represented by area under the curve.

The curve is called the probability density function (abbreviated as pdf).

We use the symbol f(x) to represent the curve

therefore

The probability density function f(x) represents . the height of the function at x.
