GUYS HELP NOW PLS WHAT IS THE PROBABILITY NOTATION FOR THE PROBABILITY OF CHOOSING A GREEN MARBLE HELPPPP PLS
guapka [62]

The probability notation for the probability of choosing a green marble is P(G)

<h3>What is probability?</h3>

This is simply defined as the extent to which something is likely to occur.

The probability that an event will occur is given as the ratio of the number of favorable outcomes to the total number of outcomes.

<h3>How to determine the probability notation</h3>

Probability notation is a symbol used in indicating the probability of an occurring event. Since our focus is on the probability of obtaining a green marble, then the probability notation will be P(G). This is illustrated below:

  • Event of green marble = nG
  • Total event = nT
  • Probability of green marble = P(G)

P(G) = nG / nT

A. 44<br> B. 112<br> C. 32<br> D. 35
Gwar [14]

Answer:

A. 44

Step-by-step explanation:

The area of a trapezoid is \frac{b_1+b_2}{2} * h, where b_1 and b_2 are the top and bottom bases, and h = height. We are given the bases as 8 and 14, and the height as 4.

  • \frac{8+14}{2} *4
  • \frac{22}{2} *4
  • 11*4
  • 44

Therefore, the answer is A. 44.

Nuts Galore sells a trail mix containing dried banana chips, roasted almonds, and chocolate chips that sells for $6.52 per pound
KengaRu [80]

Answer:

x = 28 ----- Banana

y = 54 ----- Almonds

z = 18 ---- Chocolate

Step-by-step explanation:

Let

x \to banana

y \to almonds

z \to chocolate

So, we have:

x + y + z = 100 --- total used

4x + 8y + 6z = 652 -- i.e. 6.52 * 100 --- total sales from 100 pounds

y = 3z

Required

The number of pounds of each (i.e. x, y and z)

Substitute y = 3z in x + y + z = 100

x + 3z + z = 100

x + 4z = 100

Make x the subject

x = 100 - 4z

Substitute y = 3z in 4x + 8y + 6z = 652

4x + 8 * 3z + 6z = 652

4x + 24z + 6z = 652

4x + 30z = 652

Substitute x = 100 - 4z

4(100 - 4z) + 30z = 652

400 - 16z + 30z = 652

Collect like terms

- 16z + 30z = 652-400

14z = 252

Divide by 14

z = 18

Substitute z = 18 in x = 100 - 4z

x = 100 - 4 * 18

x = 100 - 72

x = 28

To calculate y, we have:

y = 3z

y = 3 * 18

y = 54
