PLEASE HELP!!!!
Black_prince [1.1K]

Answer:

The probability that you would choose a green candy: \frac{45}{139} or approximately 32%.

Step-by-step explanation:

The general form of probability can be calculated as the following fraction:

\frac{number of desired outcomes}{total number of outcomes}

First, to find the total number of outcomes, you need to add all of the candies together:  42 + 45 + 20 + 32 = 139, so there are 139 total outcomes.  Since there are a total of 45 green candies, the probability of choosing green from the total can be written as:  

\frac{45}{139}

Dividing the numerator by the denominator and multiplying by 100 gives us the percentage of approximately 32%.

A student begins a proof of the law of cosines. His work is shown.
Phoenix [80]

The student made an error in <u>step 3</u>. To correct this error, he should define <u>side AY</u> in terms of <u>angle X</u>. <u>Pythagorean theorem</u> relates sides x, y, z, and <u>angle X</u>

<h3>The law of cosine.</h3>

In Trigonometry, law of cosine (cos) is given by this mathematical expression:

cosθ = Opp/Hyp

<u>Where:</u>

  • Opp is the opposite side of a right-angled triangle.
  • Hyp is the hypotenuse of a right-angled triangle.
  • θ is the angle.

In this scenario, we can logically deduce that the student made an error in <u>step 3</u>. To correct this error, he should define <u>side AY</u> in terms of <u>angle X</u>.

After correcting this error, the student can use the <u>Pythagorean theorem</u> to relate sides x, y, z, and <u>angle X</u>.
