SOMEONE PLEASE HELP ME WITH THIS!!!!! ITS GEOMETRY

Mathematics
1 answer:
Fudgin [204]3 years ago
5 0

Answer:

KG = 7 (A)

m KIH = 28 (B)

m JIH = 96 (D)

m HKI = 68 (B)

m KJI = 84 (C)

Step-by-step explanation:

Notice that the triangle HKJ is identical to HIJ. Since there are lines drawn to each other and both triangles are identical, the lines KG and GI are the same. This means that it is 7.

The triangle KGJ is identical with IGH. Using the recognise angle property, we know that angle JKI is the same as KHI. This means that it is 28.

Angle JIH is the same as angle JKH. Since JKH is 180 - (KHI or 84), we know that the angle JIH is 96.

We can find angle HKI by subtracting 96 by 28 because we know that angle HKI is the same as JIH. This gives us 96-2 8 = 68.

Angle KJI is the same as KHI which is 84. Therefore, KJI is also 84.

Consider the following binomial experiment. A company owns 4 machines. The probability that on a given day any one machine will
const2013 [10]

Answer:

There is a 73.11% probability that at least 2 machines will break down on a given day.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

There are 4 machines, so n = 4.

The probability that on a given day any one machine will break down is 0.53. This means that p = 0.53.

What is the probability that at least 2 machines will break down on a given day?

P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4)

In which

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{4,2}.(0.53)^{2}.(0.47)^{2} = 0.3723

P(X = 3) = C_{4,3}.(0.53)^{3}.(0.47)^{1} = 0.2799

P(X = 4) = C_{4,4}.(0.53)^{4}.(0.47)^{0} = 0.0789

So

P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.3723 + 0.2799 + 0.0789 = 0.7311

There is a 73.11% probability that at least 2 machines will break down on a given day.

HEEEELP!!!!!!: An icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 120 mm. The icicle drips at
OleMash [197]

Find the volume of the icicle using the formula V = PI x r^2 x h/3

Volume = 3.14 x 4.5^2 x 120/3

Volume = 3.14 x 20.25 x 40

Volume = 2543.4 cubic mm.

Now divide the total volume by the drip rate:

2543.4 / 75 = 33.9 minutes.

The answer is D.
