Answer: 1/3

Step-by-step explanation: In this problem, we're asked to find the probability of selecting a blue marble from a bag without looking.

Start with the ratio for the probability

of an event which is shown below.

P(event) <em>= number of favorable outcomes/total number of outcomes</em>

Since there are 3 blue marbles in a bag, the number of favorable outcomes is 3 and since there are 12 marbles in all and it's equally likely that we will choose any of the marbles, the total number of outcomes is 12 so we have 3/12.

Therefore, the probability of choosing a blue marble is 3/12.

However, notice that 3/12 can be reduced to 1/3.

So the final answer for the probability of choosing a blue marble is 1/3.

Answer:

H. 2

Step-by-step explanation:

√(1 − cos² x) / sin x + √(1 − sin² x) / cos x

Use Pythagorean identity.

sin² x + cos² x = 1

So:

1 − cos² x = sin² x

and

1 − sin² x = cos² x

Substitute:

√(sin² x) / sin x + √(cos² x) / cos x

sin x / sin x + cos x / cos x

1 + 1

What is the original price if the discount is 36% and the sale price is $32
Andrei [34K]
The answer is $50
Assume the original cost price to be $x

Therefore ,
X - 36X/100 = $32
-> 100x - 36x = 32 x 100
-> 64x = 3200
-> x = 3200/64
-> x = 50

Translate the phrase into a variable expression: twice the sum of a number and 5
DIA [1.3K]

Answer:

'Twice the sum of a number and 5' can be translated into variable expression such as:

  • 2(n + 5)

Step-by-step explanation:

Given the phrase

<em>Twice the sum of a number and 5</em>

First, let us breakdown the English Phrase

Let the number be = n

The sum of a number 'n' and 5 = n + 5

now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.

Thus,

'<em>Twice the sum of a number and 5</em>' can be translated into variable expression such as:

  • 2(n + 5)

Are collinear points coplanar?
Anna35 [415]

collinear points are points in the same line, like

●-----------------●------------------------------------------●

and the line will always be contained by a plane, so since the line is in a plane, all points in it will also be in the same plane, and therefore be coplanar.
