Find the value of x. If necessary, round to the nearest tenth

Luden [163]

Answer:

8

Step-by-step explanation:

→ Use trigonometry to find x, we have no hypotenuse so we utilise the TOA formula

TOA = Tan = Opposite ÷ Adjacent

→ The opposite of the triangle is 8√3 and we want to find the adjacent of this triangle so we rearrange

Opposite ÷ Tan

→ Substitute in the values

8√3 ÷ tan(60) = 8

A box contains 1.0 red chips, 20.bluechips, and 30 green chips. ll5 chrps are orawn lrom the box, find the probability of drawin

alexira [117]

Answer:

Step-by-step explanation:

Let S be the sample space of an experiment and E is an event associated with the experiment.

Let n(S) and n(E) denote the number of element in S and E.

P(E) is the probability of an event E

The number of elements on the sample space ;

n(S) = n(r) + n(b) + n(g) = 10 + 20 + 30 = 60

Hence, the event of drawing 5chips from the box n(S) = C(60,5)

A) probability of drawing 5chips from the box which are all blue ;

P(E) = n(E) / n(S) = 20C5 x 40C0 / 60C5 = 0.0028

by combination method ; nCr = n!/r!(n - r)!

B) the probability of drawing the indicated chips at least 1 green ;

Application of the binomial formula comes in ; nCr x p^r x q^n-r

= P(E) = 1 - p(x <1) = 1 - po = 1 - 30C0 x 30C5 / 60C5

= 0.9739

C) the probability of drawing the indicated chips at most 1 red;

P(E) = p(no red) + p(one red)

= 10C0 x 50C5 + 10C1 x 50C4 / 60C5

= 0.8096

Question and answer choices are in the SS attached!!!! Pls help me! ty!

victus00 [196]

Answer:

B

Step-by-step explanation:

It's a right triangle, so the pythagorean theorem will be used a lot.

First, find the side length on the left.

25^2 = 7^2 + y

y = 24

Now, knowing that 7 - 3 = 4 (the smaller side length), I can use this theorem again to find x.

4^2 + 24^2 = x^2

x = $\sqrt{592}$

Just need to simplify it a little farther...

592 / 16 = 37, so B must be the answer.

in a school gym, the ratio of the number of boys to the number of girls was 4:3 . after 160 boys left the gym, the ratio became

Annette [7]

Answer:

300 girls were there in the gym.

Step-by-step explanation:

Given:

The ratio of the number of boys to the number of girls was 4:3, after 160 boys left the gym, the ratio became 4:5.

Now, to find the number of girls in the gym.

The girls in the gym does not left, their quantity is same before and after.

So, we multiply the both ratios to make the girls ratio same:

4:3 × 5 = 20:15

4:5 × 3 = 12:15

Now, <em>we find the units of the ratio</em>.

<em>The ratio of boys dropped down by 160</em>:

20 - 12 = 8 units.

160 = 8 units

Now, dividing both sides by 8 we get:

20 = 1 unit

So, 1 unit = 20.

Now, girls = 15 units

So, 15 × 20 = 300.

Therefore, 300 girls were there in the gym.
