<u>Geometry</u>

  • Diameter: d = 2r
  • Area of a Circle: A = πr²

Step-by-step explanation:

<u>Step 1: Define</u>

d = 30 m

<u>Step 2: Find Area</u>

  1. Substitute [D]:                    30 m = 2r
  2. Isolate <em>r</em>:                             15 m = r
  3. Rewrite:                              r = 15 m
  4. Substitute [AC]:                 A = π(15 m)²
  5. Rearrange:                        A = 15²π

I will give you brainly for the best and fastest answer
Natali [406]

Replace y in the second equation with the value of Y from the first equation:

-x - 3 = 5

Add 3 to both sides:

-x = 8

Multiply both sides by -1:

x = -8

The answer is:

(-8,3)

Please help!!
damaskus [11]

Answer:

6a) 1

6b) 11

7a) 4

7b) 10

8a) 6

8b) 14

9a) 11

9b) 13

Step-by-step explanation:

In order to make a triangle, we need to follow this property:

a <= b + c

(Known as "triangle inequality")

Where 'a' is the bigger side and 'b' and 'c' are the other two sides.

So, using this property, we can solve the following problems:

6a) Maximum side will be 6:

6 <= 5 + c

c = 1

6b) Minimum sides will be 5 and 6:

a <= 5 + 6

a = 11

7a) Maximum side will be 7:

7 <= 3 + c

c = 4

7b) Minimum sides will be 3 and 7:

a <= 3 + 7

a = 10

8a) Maximum side will be 10:

10 <= 4 + c

c = 6

8b) Minimum sides will be 4 and 10:

a <= 4 + 10

a = 14

9a) Maximum side will be 12:

12 <= 1 + c

c = 11

9b) Minimum sides will be 1 and 12:

a <= 1 + 12

a = 13

One thousand independent rolls of a fair die will be made. Compute an approximation to the probability that the number 6 will ap
pashok25 [27]

Answer:

0.19

Step-by-step explanation:

We are given that

Number of rolls of die=n=1000

Let the event of six coming up be success.Then, in each trial , the probability of success =p=P(success)=P(6)=\frac{1}{6}

Let X be the random variable  for the number of sixes  in the 1000 rolls of die.

Then, X\sim Binom(1000,\frac{1}{6})

Since, n is very large,the binomial random variable can be approximated as normal random variable.

Mean,\mu=np=1000\times \frac{1}{6}=166.67

Variance=\sigma^2=np(1-p)=1000\times \farc{1}{6}\times (1-\frac{1}{6})=1000\times \frac{5}{36}=138.89

X\sim N(166.67,138.89)

P(150\leq X\leq 200)=P[\frac{150-166.67}{11.79}\leq \frac{X-\mu}{\sigma}\leq \frac{200-166.67}{11.79}]

=P[-1.41\leq Z\leq 2.83]=P[Z\leq 2.83]-P[Z

=\phi(2.83)-\phi(-1.41)

=0.9977-0.0793=0.9184

Thus, the probability that the number 6 appears between 150 to 200 times=0.92

Now, given that 6 appears exactly 200 times .

Therefore, other number appear in other 800 rolls .

We have to find the probability that the  number 5 will appear less than 150 times.

Therefore, for 800 rolls, let the event of 5 coming up be success.

Then , p=P(success)=P(5)=\frac{1}{5}

Let Y be the random variable denoting the number of times  5 coming up in 800 rolls.

Then, Y\sim bin(800,\frac{1}{5})

Mean,\mu=np=800\times \frac{1}{5}=160

Variance, \sigma^2=np(1-p)=800\times \frac{1}{5}(1-\frac{1}{5})=128

Y\sim N(160,128) because n is large

P(Y

P(Y

Hence, the probability that the number 5 will appear less than 150 times given that 6 appeared exactly 200 times=0.19
