Answer:

The odds against drawing an eight are \frac{12}{13}

Step-by-step explanation:

If there are 52 cards in a deck, 13 cards a suit and 4 suits, that means there are four eights in the deck, one of every suit.

That means, the probability of drawing an eight is:

P_{eight}=\frac{number of eights}{cards} =\frac{4}{52}=\frac{1}{13}

As we want to find the odds against drawing an eight, we want to find the probability of not drawing an eight.

The probability of drawing or not drawing an eight is one (the probability of taking a card if we take a card), and as they are not independent, we know that we have to sum those probabilities:

P_{card} =P_{eight}+P_{not eight}= 1

Then, we can find the probability of not drawing an eight:

P_{not eight}= 1- P_{eight}=1-\frac{1}{13} =\frac{12}{13}

That means, in average, 12 out of 13 times we will not draw an eight.

What is the height of this isosceles triangle?
erastova [34]

Answer:

height ≈ 11.9 units

Step-by-step explanation:

Construct a perpendicular bisector from the vertex to the base, thus splitting the triangle into 2 right triangles.

Using the sine ratio in one of these right triangles, then

sin48° = \frac{opposite}{hypotenuse} ( the opposite is the height h )

sin48° = \frac{h}{16} ( multiply both sides by 16 )

16 × sin48° = h , thus

h ≈ 11.9 ( to the nearest tenth )

Morgan is reupholstering an old chair with two circular cushions. Each cushion has a circumference of 7. 85 feet. He will need t
kramer

The total fabric Morgan needs to cover the cushions will be 19.64 square feet.

It is given that each cushion has a circumference of 7.85 feet.

It is known that the circumference of a circle = 2πr, where 'r' is the radius of the circle.

2πr = 7.85

r = 1.25

<h3>What is an area of a circle?</h3>

area of a circle is πr².

now, we can calculate the area = π× 1.25² = 4.91 square feet

since each circular cushion has two circular faces so the total number of faces Morgan needs to cover will be 4.

Therefore, the total fabric needed= 4×4.91 = 19.64 square feet.

to get more about the area of a circle, refer to the link:
