In an experiment, the probability that event A occurs is 5/8 , the probability that event B occurs is 2/9 , and the probability that events A and B both occur is 1/5 . What is the probability that A occurs given that B occurs?

Answers

Answer 1

Step-by-step explanation:

p(A|B) = p(A and B) / p(B) =(1/5) / (2/9) = 0.9

Answer 2

The probability that event A occurs is 5/8 , the probability that event B occurs is 2/9 , and the probability that events A and B both occur is 1/5 . The probability that A occurs given that B occurs is 0.9.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

The probability that event A occurs is 5/8

The probability that event B occurs is 2/9

The probability that events A and B both occur is 1/5.

So, The probability that A occurs given that B occurs

P(A|B) = P(A and B) / P(B)

          = (1/5) / (2/9)

          = 0.9

Answer:

4.41

Step-by-step explanation:

We can use trig to solve for the missing side (specifically cosine).  cos(x)=adjacent side/hypotenuse.  We have the x value (which is the angle shown) which is 25.  We have the adjacent side of that angle which is 4.  We are solving for the hypotenuse (lets call that h).  When we plug in values into the equation cos(x)=adjacent/hypotenuse, we get cos(25)=4/h.  cos 25=0.9063.  So 0.9063=4/h.  Multiply both sides by h and we get 0.9063h=4.  Now divide 0.9063 on both sides to isolate h and we get 4.4135... but since you want hundredths, its 4.41

Prime factors of 24x2

Answers

Answer:

Step-by-step explanation:

24 is a composite number.

Prime factorization: 24 = 2 x 2 x 2 x 3, which can be written 24 = 2³ x 3

The exponents in the prime factorization are 3 and 1. Adding one to each and multiplying we get (3 + 1)(1 + 1) = 4 x 2 = 8. Therefore 24 has exactly 8 factors.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Factor pairs: 24 = 1 x 24, 2 x 12, 3 x 8, or 4 x 6

A laboratory tested n = 110 chicken eggs and found that the mean amount of cholesterol was LaTeX: \bar{x}x ¯ = 92 milligrams with σ = 8 milligrams. Find the margin of error E corresponding to a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs.

Answers

Answer:

The margin of error corresponding to a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs is of 1.495 miligrams.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]

Now, find the margin of error E as such

[tex]E = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

In this question:

[tex]\sigma = 8, n = 110[/tex]. So

[tex]E = 1.96\frac{8}{\sqrt{110}} = 1.495[/tex]

The margin of error corresponding to a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs is of 1.495 miligrams.

The figure shown in the right is made up of a square and a circle. Find the perimeter of the shaded region.

A. 16+2π cm
B. 12+2π cm
C. 12+4π cm
D. 16+4π cm

Answers

Answer:

B. 12 + 2pi cm

Step-by-step explanation:

The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.

The circle's circumference can be found by using the equation c = (d)pi

The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.

Add them all together, and you get 12 + 2pi cm.

if you have 3,500 after 10 years on an investment that pays 3.5% compounded daily, what was the principle amount you started with ?

Answers

Answer: $2,466.45

Step-by-step explanation:

Hi, to answer this question we have to apply the compounded interest formula:

A = P (1 + r/n) nt

Where:  

A = Future value of investment (principal + interest)  

P = Principal Amount  

r =  Nominal Interest Rate (decimal form, 3.5/100= 0.035)

n=   number of compounding periods in each year (365)

Replacing with the values given

3,500= P (1+ 0.035/365)^365(10)

Solving for P

3,500= P (1.00009589)^3650

3,500/  (1.00009589)^3650 =P

P = $2,466.45

A farmer sells 6.5 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmers market?

Answers

Answer:

1.625 kilograms

Step-by-step explanation:

Since total weight of pears and apples is 6.5 kilograms and 3/4 of this weight is pears, the weight of the pears is

→ 6.5 x 3/4 = 4.875 kilograms

Since the weight of the pears is 4.875, we can subtract it from the total weight to find the weight of the apples

→ 6.5 - 4.875 = 1.625 kilograms

Answer:

1.625 kg

Step-by-step explanation:

Total weight sold by the farmer =6.5 kilograms

If 3/4 of the weight is pears:

Weight proportion of apple[tex]=1-\frac{3}{4}= \frac{1}{4}[/tex]

Therefore:

Weight of Apples sold at the market [tex]= \frac{1}{4} X 6.5 kg\\[/tex]

=1.625 kg

The farmer sold 1.625 kilograms of apple.

A cone has a volume of 96 'pi' cubic feet. if the radius is 6 feet, what is the height of the cone?

A.8
B.32 ​

Answers

Answer:

height of the cone = 8 ft

Step-by-step explanation:

A cone has a volume of 96π ft³. The radius of the cone is 6 ft. The height of the cone can be computed below .

The volume of a cone can be represented as follows

volume of a cone = 1/3πr²h

where

r = radius

h = height

volume of a cone = 1/3πr²h

volume = 96π ft³

r = 6 ft

h = ?

96π = 1/3 × π × 6² × h

96π = 1/3 × π × 36 × h

96π = 12πh

divide both sides by 12π

h = 96π/12π

h = 8 ft

height of the cone = 8 ft

Gdy Artur ukończył bieg, Olga miała 15 m do mety, a Wiktor miał 35 m. Gdy Olga ukończyła bieg, Wiktorowi pozostały 22 m do mety. Na jakim dystansie został rozegrany wyścig?

Answers

Answer:

165m

Question:

Artur, Olga and Wiktor participated in the race. They started from the same place at the same time and run at constant speeds. When Artur finished the race, Olga was 15 m to the finish, and Wiktor was 35 m. When Olga finished the race, Wiktor had 22 m to the finish. At what distance was the race held?

Explanation:

Let distance be x meters

Fist statement:

Artur distance = x

Olga =x-15

Wiktor = x-35

Since they are going at constant speed, time is constant for all 3.

Their speed = distance/time

x/t, (x-15)/t, (x-35)/t respectively

Second statement:

Olga distance = x

Wiktor distance = x-22

Their Time is constant:

If it takes (x-15) in t secs,

for x meters will take = xt/(x-15)

Olga and wiktor respectively: xt/(x-15), xt/(x-15) respectively

Their speed:

Speed = distance/time

Olga = (x-15)/t,

Wiktor = (x-22)(x-15)/(xt)

Since speed is constant

Speed for Wiktor in both cases:

(x-35)/t =(x-22)(x-15)/(xt)

x(x-35) =(x-22)(x-15)

x² -35x = x² - 15x -22x +330

-35x = -37x +330

2x = 330

x = 165m

Race held at 165m distance.

Javier's parents set an amount of money aside when he was born. They earned 4.5% simple interest on that money each year. When Javier was 15, the account had a total of $1012.50 interest paid on it. How much did Javier's parents set aside when he was born

Answers

Answer:

Javier's parents set aside $1500 when he was born

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E is the interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question, we have that:

[tex]E = 1012.50, t = 15, I = 0.045[/tex]

We have to find P. So

[tex]E = P*I*t[/tex]

[tex]1012.50 = P*15*0.045[/tex]

[tex]P = \frac{1012.50}{15*0.045}[/tex]

[tex]P = 1500[/tex]
