Laura found an old deck of cards in her drawer which had only eight face cards: king of hearts (H), king of spades (S), king of

clubs (C), king of diamonds (D), queen of hearts (H), queen of spades (S), queen of clubs (C), and queen of diamonds (D). Laura and her sister separated the kings and queens into a king deck and a queen deck. They created a game where they draw one card from each deck.
The table below shows all the possible outcomes they can draw.

Outcomes Queen(H) Queen(S) Queen(C) Queen(D)
King(H) King(H),
Queen(H) King(H),
Queen(S) King(H),
Queen(C) King(H),
Queen(D)
King(S) King(S),
Queen(H) King(S),
Queen(S) King(S),
Queen(C) King(S),
Queen(D)
King(C) King(C),
Queen(H) King(C),
Queen(S) King(C),
Queen(C) King(C),
Queen(D)
King(D) King(D),
Queen(H) King(D),
Queen(S) King(D),
Queen(C) King(D),
Queen(D)

What is the probability of Laura and her sister drawing a king that is not the king of hearts, and a queen that is not the queen of spades?

Select the correct answer from each drop-down menu.
Ahat [919]

Answer:

Cos θ  = -4/5

Tan θ = -3/4

Step-by-step explanation:

The question is as following:

Select the correct answer from each drop-down menu.

Angle θ lies in the second quadrant, and sin θ =3/5.

cos θ = -4/5, -3/5, 3/5, 4/5

tan θ = -4/3, -3/4, 3/4, 4/3

==================================================

Since, the angle lies in second quadrant (negative x axis and positive y axis) we can deduce that cos θ is negative and tan θ is also negative.

If sin θ =3/5

cos \  \theta =\sqrt{1-sin^2 \theta} = \sqrt{1-(\frac{3}{5} )^2} =\sqrt{1-\frac{9}{25} }=\sqrt{\frac{16}{25} } =\frac{4}{5}

∴ Cos θ = -4/5 ⇒ because θ lies in the second quadrant.

And

Tan θ = (sin θ)/(cos θ) = (3/5) / (-4/5) = -3/4.

I need help!
Naddik [55]

Answer:  Estimate: 36  ? units ? miles per hour ? feet per second?

Exact: 35.32142857  but if you are supposed to use significant digits, 35.32 is probably good.

Step-by-step explanation: For the estimate, round off the fractions to whole numbers, so multiply 6 x 6 to get 36

For exact I converted the mixed numbers to improper fractions, 5 3/4 = 23/4  and 6 1/7 = 43/7. Then multiplied the numerators 23 x 43= 989.  And denominators, 4x7=28.  

Divide numerator by denominator  989/28= 35.321428571

How many times larger is 700 than 70?
Strike441 [17]
When it comes to hundreds and thousands and even millions, you can tell how much bigger something is by how many more zeros are at the end. Each new zero added, is another rank up. The system goes:

1=10x bigger
2=100x bigger
3=1000x bigger
4=10000x bigger 
5=100000 bigger

so on and so forth. There are 2 zeros in 700, and only 1 zero in 70, the difference in zeros is 1, so you can refer to the chart and conclude that 700 is 10 times bigger than 70. You could also divide 700 by 70 to get 10. This is more accurate, but the chart is simpler.
