On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places

Answers

Answer 1

Answer:

The probability that two of them

die is 0.257

Step-by-step explanation:

From the question, we have that the mortality rate is 0.1

So the probability that they will survive is 1-0.1 = 0.9

Now, we want to check that two will die

We are going you use the Bernoulli approximation of the Binomial theorem as follows

= nCr * p^n * q^(n-r)

where n = 16

r = 2

P = 0.1

q = 0.9

Substituting these values;

14 C 2 * 0.1^2 * 0.9^12

= 0.257

Find each of the following angles and arcs formed in circle R. (PLEASE HELP!! WILL MARK BRAINLIEST!)

Answers

Answer:

m<RTV = 90°

m<TRU = 129°

m<TVU = 51°

m<TSU = 64.5°

mST = 101°

mSTU = 230°

Step-by-step explanation:

i just did it:)

The measure of each angles are; m<RTV = 90°, m<TRU = 129°, m<TVU = 51°, m<TSU = 64.5°, mST = 101° and mSTU = 230°.

What is a circle?

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

Since Angle RTV is formed by the segments RT - that is the radius of the circle, and TV, which is tangent to the circle at point T. The radius always forms a right angle with the tangent lines.

Hence, the measure of angle RTV is; 90°.

The measure of a central angle and the measure of the intercepted arc would be equal. Hence, the measure of angle TRU is 129°.

Since RTVU is a quadrilateral. We know that 3 of the interior angles' measures are 90°, 90°, and 129°. The measures of the interior angles of any quadrilateral add up to 360°, the measure of angle TVU is 51°.

Thus the measure of angle TSU is 64.5°.

Also the sum of all consecutive arcs in a circle is 360°,

We know that mTU = 129° and mUS = 130° then the measure of arc ST is 101°.

Answers

Answer:

54

Step-by-step explanation:

80 Customers divide that by 2 =40

So if 120 Customers were to order then you would just add 18 to 36 and that would make it 54.

Basically just find how many clubs are bought in 40 customers then multiple it by 3

I run a business. It costs £54,000 a year. Most of the money goes on paying wages. The ratio of wages to other costs is 2 : 1. How much do I spend on wages every year?

Answers

Answer:

2 × 54,000 ÷ (1+2)

£36,000

Step-by-step explanation:

Total cost of the business = £54,000

wages : other costs = 2 : 1

Total ratio = 2 + 1 = 3

How much do I spend on wages every year?

Amount spent on wages yearly = ratio of wages / total ratio × Total cost of the business

= 2 × 54,000 ÷ (1+2)

= 2/3 × £54,000

= £108,000/3

= £36,000

Amount spent on wages yearly = £36,000

2(L*W)+2(L*W)+2(L*W)= surface area

You have a recipe that indicates to use 4 parts of flour for every 3 parts of sugar. You use 16 cups of flour. How much sugar do you need?

Answers

Answer:

9

Step-by-step explanation:

Tell me if you want me to explain in the comments

There are 12 cups of sugar.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

You have a recipe that indicates to use 4 parts of flour for every 3 parts of sugar.

Now,

Let the number of cups of sugar for 16 cups of flour = x

So, By definition of proportion we get;

⇒ 4 / 3 = 16 / x

Solve for x as;

⇒ 16 / x = 4 / 3

⇒ 16 × 3 / 4 = x

⇒ 4 × 3 = x

⇒ x = 12

Thus, There are 12 cups of sugar.

Given the area of a trapezoid is 86 in’, and the height is 4 in. If one base is 18 in, determine the other base.

Answers

Answer:

25 = base

Step-by-step explanation:

I searched all of this on YT to try and help

so first we need to know the area of a Trapezoid

A = 1/2h(b + b)

86 = 1/2(18 + b)4

we dont know the base where going to put b

we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.

172 = (18 + b)4

the 4 is multipling so divide it on both ends.

43 = (18 + b)

then do the opposite operation on the 18, by subtracting 18 on both sides.

25 = b

is the base

check the work by plugging it back in

A = 1/2h(b + b)

A = 1/2 4(18+25)

A = 1/2 4(43)

A = 1/2(172)

A = 86in

By the way, can you follow me on Brainly?

Thanks!

Answer:

5/2, or 2 1/2

Step-by-step explanation:

To find the value of h you want to get h by itself, so you must subtract 4 1/2 from both sides of the equation. 4 1/2 can be rewritten as 9/2, but you must find a common denominator between 7 and 9/2. A common denominator can be 2, if 7 is changed into 14/2. The equation is now 14/2 - 9/2, which gives you 5/2 or 2 1/2.

Step-by-step explanation:

A translation only moves vertically or (and) horizontally our image.

This means that a translation does not change the size

A translation does not rotate the image.

Then a translation of triangle 1 needs to have the same size than triangle 1, and the same "direction" (in triangle 1 we can see that the hypotenuse is at the right side, then in the translated triangle we also should have the hypotenuse at the right side).

Then the only option that seems correct is triangle 4

Step-by-step explanation:

Identifying the greatest common factor of an expression like this one involves finding the GCF of each term  when the terms are placed side by side:  the GCF of -15x^3 and 6x^4 is 3x^3, because 3 and x^3 are the largest factors of their type (constant, power of x) that will divide evenly into -15x^3 and 6x^4.

The end result is 3x^3(-5, 2x).  Once again, the GCF is 3x^3.
