A person draws a card from a hat. Each card is one color with the following probabilities of being drawn: 1/10 for red, 1/5 for

Kay [80]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

We are given that a card is drawn from a hat.

Probability that a red card is drawn, P(red) = $\frac{1}{10}$

Probability that a blue card is drawn, P(blue) = $\frac{1}{5}$

Probability that a black card is drawn, P(black) = $\frac{1}{20}$

Probability that a pink card is drawn, P(pink) = $\frac{1}{5}$

All these events are mutually exclusive i.e. they do not have anything in common.

For any two events A and B which are mutually exclusive, with probability P(A) and P(B), the probability that any one of the two events occur:

$P(A\cup B) = P(A) + P(B)$

Here event A can be thought of as drawing a blue card and

event B can be thought of as drawing a black card

So, P(blue or black) = P(blue) + P(black)

$\Rightarrow \dfrac{1}{5}+\dfrac{1}{20}\\\Rightarrow \dfrac{4+1}{20}\\\Rightarrow \dfrac{5}{20}\\\Rightarrow \dfrac{1}{4}$

So, the probability that a blue or black card is drawn from the hat:

$\dfrac{1}{4}$

The perimeter of a rectangular garden is 9696 meters. The length is 6 meters longer than twice the width. Find the dimensions of

nalin [4]

length = 3234 m and width = 1614 m

let the width = w then length = 2w + 6

Perimeter = 2 ( length + width )

= 2 (2w + 6 + w ) = 2 ( 3w + 6 ) = 6w + 12

given perimeter = 9696 the equating gives

6w + 12 = 9696

subtract 12 from both sides

6w = 9696 - 12 = 9684

divide both sides by 6

w = $\frac{9684}{6}$ = 1614

width = 1614 m and length = (2 × 1614 ) + 6 = 3234 m

Which is bigger 7/8 or 0.78

agasfer [191]

<span>7/8 = 7 * 1/8 and 1/8 = 1 : 8 = 0.125. After that: 7 * 0.125 = 0.875. Finally, 0.875 > 0.78. We can do it also by transforming 0.78 to fraction: 0.78 = 78/100 = 39/50 and then multiplying the numerator and the denominator by 4: 39/50 = 156 / 200 . Then we will also multiply 7/8 * 25/25 = 175/ 200. Obviously: 175/200 > 156/200. Answer: 7/8 is bigger than 0.78. </span>

Does anyone understand and can help me asap?

nydimaria [60]

Answer:

see below

Step-by-step explanation:

Circumference of circle = 2πr =dπ

Area of circle =πr²

1) Circle1 d =4 in, r =2 in

Circumference of circle1 =4π in

Area of circle1 = 2²π =4π in²

2) Circle2: d =3 in, r =1.5 in

Circumference of circle2 =3π in

Area of circle2 = 1.5²π =2.25π in²

3) Circle3: r =1 in, d =2 in

Circumference of circle3 =2π in

Area of circle3 = 1²π =π in²

4) Circle4: r =2 1/2 in = 2.5 in, d =5 in

Circumference of circle4 =5π in

Area of circle4 = 2.5²π = 6.25π in²

5) 2/3 of the Area of circle1 = (2/3)*4π in²= (8/3)π in²

6) 1/2 of the Area of circle2 = (1/2)*2.25π in² = (1/2)*(9/4)π in² = (9/8)π in²

7) 1/4 of the Area of circle3 = (1/4)π in²

8) 1/3 of the Area of circle4 = (1/3)* 6.25π in² =(1/3)*(25/4)π in² = (25/12)π in²
