One card is randomly selected from a deck of cards. Find the odds against drawing a three​

Mathematics

The answer is 12:1

note: this is often read as "12 to 1"

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

Explanation

We have exactly four card that are labeled "3" and 52 cards total. So there are 52-4 = 48 cards that are not labeled "3".

From here you write the ratio 48:4 to indicate the odds against drawing a 3. There are 48 ways to lose, 4 ways to win. You list the number of ways to lose first when it comes to "odds against" type of problems.

Next step is to reduce the ratio 48:4 to get 12:1, note how I divided both parts by the GCF 4

48/4 = 12

4/4 = 1

So thats how 48:4 reduces to 12:1

If you focus on one suit, say the spades, then we have 12 cards that arent a 3 of spades while exactly one card is a 3 of spades. This is one way to see why 12:1 is the answer. If you were saying this out loud to a friend, then you might say something like "the odds against drawing a three are 12 to 1".

Answer:

Just so you hear, Whirlybot,  these circle problems are always "tricks"  and they are tough.  You have to remember a bunch of implied things

Step-by-step explanation:

One thing to recall is that the angle from the tangent point to O at the center is also a 90° angle.  so you now know, that the line from the point where the circle touches the tangent line to the center is a right angle and you have part of that 90° already.  the 50 is one part and there for the next part is 40 °  Since we now know that the line from the tangent to the center is forming an internal angle with that line going to X of 40 °  we know that X is also 40 ° b/c the triangle formed by the line to the center is going to be the same length as the line from the center to the X.  That's an Isosceles triangle.  they have the same angles at the two same length legs.  

I know, I went thur a whole pile of logic, but that's what makes this kind of problem tough.   you just have to keep thinking about things you know.

X = 40 °

When Elena makes bird food, she usually mixes 9 cups of seeds with 6 tablespoons of maple syrup. However, today she is short on
svetlana [45]

Answer:3 cups of seeds and 2 tablespoons of maple syrup

-OR-

6 cups of seeds and 4 tablespoons of maple syrup

Step-by-step explanation:

As this is a ratio of 9:6: "for every 9 cups of seeds, there is 6 tablespoons of maple syrup"

The original ratio is 3:2 "for every 3 cups of seeds, there is 2 tablespoons of maple syrup"

Using this ratio, we can infer that 3:2 or 6:4 would be a simpler answer for this problem. If there is doubt, it would be better to use 3:2 as it is the smallest ratio.

This isn't as hard as it looks.
The ratio is 1 to 12.
You just have to multiply the model value by 12.

12 x 5.4 = 64.8 feet. Now, the answer has to be in yards, so divide by 3.
64.8 div 3 = 21.6 feet.

The vector v=(7,1) lies entirely in quadrant 1. Give possible coordinates for the initial point and terminal point of the vector
slamgirl [31]

Answer:

A possible initial point is (1,4) and a possible terminal point is (8,5)

Step-by-step explanation:

The given vector is \vec{v}=(7,1).

We can rewrite this vector as:

\vec{v}=\binom{7}{1}

The x-components is 7 and the y-component is 1.

We can choose initial point (a,b) and terminal point (c,d) in the first quadrant such that c-a=7  and d-b=1

If a=1, and b= 4, then:

c-1=7  and d-4=1

This implies that:

c=7+1=8  and d=1+4=5

Therefore a possible initial point is (1,4) and a possible terminal point is (8,5)
