An experiment consists of rolling a standard six-sided die once. Event A is "rolling an even number" and event B is "rolling a 2
OleMash [197]

Answer:

(D)Events A and B are dependent, because P(B)≠P(B|A).

Step-by-step explanation:

<u>Definition:</u> Two events are independent if

P(A)\cdot P(B)=P(B\cap A)\\$Equivalently:$\\P(B)=\frac{P(B\cap A)}{P(A)} \\P(B)=P(B|A)

An experiment consists of rolling a standard six-sided die once.

Event A is "rolling an even number"

Even numbers are 2,4 and 6

  • P(A)=3/6=1/2

Event B is "rolling a 2."

  • P(B)=1/6

\{A\cap B\}={2}\\P(A\cap B)=1/6

Substitution into P(B)=\frac{P(B\cap A)}{P(A)}

Left Hand Side =1/6

Right Hand Side =(1/6)÷(1/2)=1/3

Since P(B)\neq \frac{P(B\cap A)}{P(A)}, therefore P(B)\neq P(B|A) which makes the events dependent.

The length of a rectangle is 4 inches longer than the width. The perimeter is 48 inches. What is the width?
amid [387]

Answer:

w = 10 in

Step-by-step explanation:

Perimeter is the measure of the length of all sides

48 = 2L + 2w

L = w + 4

^ use substitution

48 = 2(w + 4) + 2w     simplify.

48 = 2w + 8 + 2w       combine like terms

48 = 4w + 8           then subtract 8 from both sides

40 = 4w     then divide by 4 to isolate w

10 = w

Ezra is baking cookies his recipe uses 200 grams of sugar to make 48 cookies. He wants to know how many cookies he can make with
Tcecarenko [31]

We are asked to find the proportion of sugar to number of cookies

Sugar = 200g

Number of cookies = 48

proportion of sugar to cookies = 200 : 48

how many cookies he can make with 350 grams of sugar?

let x = number of cookies

proportion of sugar to cookies = 350 : x

equate the <em>proportions</em>

200 : 48 = 350 : x

200/48 = 350/x

cross product

200 × x = 350 × 48

200x = 16800

x = 16800/200

x = 84 cookies

find the number of cookies, y, Ezra can make with x grams of sugar?

y = grams of sugar, x / number of cookies

y = 350/84

y = 4.17x

Therefore,

Ezra can make 84 cookies with 350 grams of sugar
