A jar contains 2 orange, 4 green, 2 white and 2 black balls. What is the probability of drawing an orange ball without putting i
KonstantinChe [14]

Answer:

2/45

Step-by-step explanation:

We are told that:

A jar contains 2 orange, 4 green, 2 white and 2 black balls.

The total number of balls in the jar is calculated as:

2 orange balls + 4 green balls + 2 white balls + 2 black balls = 10 balls

The probability of drawing an orange ball = P(Orange) = 2/10

The probability of drawing a black ball = P(Black) = 2/10

Therefore, the probability of drawing an orange ball without putting it back, then drawing a black ball is calculated as:

2/10 × 2/9 = 4/90

= 2/45

Help please. I’m stuck on this one
Nastasia [14]

Answer:

b = 25m

Step-by-step explanation:

Hi there!

We're given angle B and the length of <em>a</em> in this right triangle. We must solve for the length of <em>b</em>. <em>a</em> and <em>b</em> are the two legs of the right triangle.

In this case, we can use the tangent ratio:

tan\theta=\displaystyle\frac{opposite}{adjacent}

Plug in the given information:

tan\displaystyle\frac{\pi}{4} =\displaystyle\frac{b}{25}\\\\25tan\displaystyle\frac{\pi}{4} =b\\\\b=25

Therefore, b = 25m.

We can also use this using special triangle rules. \displaystyle\frac{\pi}{4} radians is equal to 45 degrees, making this a 45-90-45 triangle. This would make <em>a</em> and <em>b</em> equal in length.

I hope this helps!
