Answer:

$636.53

Step-by-step explanation:

Tax: 9.75/100 × 579.98

= 56.54805

Total cost = 579.98 + tax

= 636.52805

A coin is tossed 4 times. Let E1 be the event "the first toss shows heads" and E2 the event "the second toss shows heads" and so

Elden [556K]

Answer:

The events are independent.

The probability of showing heads on both toss is equal to 1/2

Step-by-step explanation:

The sample space for this experiment consists of 2⁴= 16 sample points, as each toss can result in two outcomes we assume that the events are equally likely.

Two events are independent in the sample space if the probability of one event occurs, is not affected by whether the other event has or has not occurred.

In general the k events are defined to be mutually independent if and only if the probability of the intersection of any 2,3,--------, k equals the product of their respective probabilities.

P (A∩B) = P(A). P(B)

P (A∩B) = 1/2. 1/2= 1/4

Head Tail

P(E1)= 1/2 ---------- Coin 1 H,H T,H

1/4 1/4

P(E2)= 1/2 --------------- Coin 2 H, H H,T

1/4 1/4

So the events are independent.

The probability of showing heads on both toss is equal to 1/2

The sample space for this experiment consists of 2⁴= 16 sample points, out of which eight will have heads on both toss.

Or in other words ( 1/4* 1/4) = 2/4 = 1/2

What is the value of x to the nearest tenth? A 14. B 14.4. C 13.5. D 13.2

Ivan

Answer:

x=13.5

Step-by-step explanation:

sin 48 = opposite/ hypotenuse

sin 48 = 10/x

multiply by x on each side

x sin 48 =10

divide by sin 48

x = 10/sin 48

x = 13.456

round to the nearest tenth

13.5

The perimeter of a particular square and the circumference of a particular circle are equal. What is the ratio of the area of th

oksano4ka [1.4K]

<h2>Ratio of area of the square to the area of the circle = π/4</h2>

Step-by-step explanation:

Let the side of square be a and radius of circle be r.

The perimeter of a particular square and the circumference of a particular circle are equal.

Perimeter of square = 4 x a = 4a

Circumference of circle = 2πr

Given that

4a = 2πr

$a=\frac{\pi r}{2}$

We need to find the ratio of the area of the square to the area of the circle.

Area of the square = a²

Area of the circle = πr²

$\texttt{Ratio of area of the square to the area of the circle =}\frac{a^2}{\pi r^2}\\\\\texttt{Ratio of area of the square to the area of the circle =}\frac{\left ( \frac{\pi r}{2}\right )^2}{\pi r^2}\\\\\texttt{Ratio of area of the square to the area of the circle = }\frac{\pi}{4}$

Ratio of area of the square to the area of the circle = π/4

sergejj [24]

Answer:

210 1/8 ft²

Step-by-step explanation:

The length of the living room is 20 1/2

the width is half as long as the length

(20 1/2)/2=10 1/4

so the width is 10 1/4

A=LW so

A=(10 1/4)(20 1/2)

So A=

210 1/8 ft²
