Answers

Answer:

11253.76

Step-by-step explanation:

We know that the formula for the volume of a cylinder is pi(r^2)(h) and we have both the radius (8 yards) and the height (56 yards) given to us. Given this, we can plug those numbers into the equation and do pi x (8)^2 x 56 which is simplified to 3.14 x 64 x 56, and when we solve this out we can get a final answer of 11253.76

The lengths of text messages are normally distributed with a population standard deviation of 6 characters and an unknown population mean. If a random sample of 27 text messages is taken and results in a sample mean of 25 characters, find a 95% confidence interval for the population mean. Round your answers to two decimal places. z0.10 z0.05 z0.04 z0.025 z0.01 z0.005 1.282 1.645 1.751 1.960 2.326 2.576 You may use a calculator or the common z-values above.

Answers

Answer:

(22.74 ; 27.26)

Step-by-step explanation:

The confidence interval relation is stated as :

Mean ± Zcritical * σ/sqrt(n)

Mean = 25

σ = 6

The Zcritical at 95% = 1.96

Hence,

25 ± 1.96 * (6/sqrt(27))

25 ± 1.96 * 1.1547005

Lower boundary :

25 - (1.96 * 1.1547005) = 22.73678702

Upper boundary :

25 + (1.96 * 1.1547005) = 27.26321298

In Normal distribution(z) tomato plants have height less than 4.07 feet is 97.93 %.

What is normal distribution?

Normal distribution is a "continuous probability distribution that its symmetrical around its mean with most values near the central peak".

According to the question,

The heights of tomato plants are Normally distributed.

Mean(μ) = 3.56

Standard deviation (σ) = 0.25

For a tomato plants that has a height of 4.07 feet

In order to find Percentage of tomato plants have a height less than 4.07 feet

Standard Normal Distribution Formula,

z = (x-μ)/σ where X~(μ,σ).

= [tex]\frac{4.07-3.56}{0.25}[/tex]

= [tex]\frac{0.51}{0.25}[/tex] = 2.04.

P ( x < 4.05) = P( z < 2.04 )

= 0.9793 ( Using standard Normal distribution table)

To find the percentage of tomato plants have height less than 4.07 feet is

multiply 0.9793 by 100

= 97.93%

Hence, Using Standard Normal distribution we find tomato plants have height less than 4.07 feet is 97.93 %

How many liters of 30% salt solution must be added to 6 L of an 80% salt solution to obtain a 50% salt solution

Answers

Answer:

9 Liters

Step-by-step explanation:

Let us represent:

The number of liters of the 30% salt solution = x

Number of liters for the 80% solution = 6 Liters

Number of liters for the 50% solution = x + 6 Liters

Hence:

x × 30% + 6 × 80% = (x + 6)50%

0.3x + 4.8 = 0.5x + 3

Collect like terms

4.8 - 3 = 0.5x - 0.3x

1.8 = 0.2x

x = 1.8/0.2

x = 9 Liters

Therefore, the number of liters for the 30% Salt solution = 9 Liters

Find the value of x

A. 5 square root 2/2
B 5
C 10
D 10 square root 2

Answers

Answer:

The answer is C

Step-by-step explanation:

That side with the 5 is equal to 7.071067812.... (irrational number)

To get x you need to use the equation a^2 + b^2 = c^2

A^2 and B^2 will both be the same thing. The red line indicates they are the exact same length.

7.071037812.... ^2 is 50

Now your equation would be 50+50= c^2 (which is the same as x^2)

100= c^2 is simplified by finding the square root of 100.

Your answer is 10 for side X because the square root of 100 is 10.

This problem was solved using the Pythagorean Theorem.

The hypotenuse x of the right triangle is (c) 10

Finding the hypotenuse, x of the right triangle

From the question, we have the following parameters that can be used in our computation:

The right triangle

Where, we have

Leg a = 5√2

Leg b = 5√2

The hypotenuse of the right triangle can be calculated using the following Pythagoras theorem

h² = a² + b²

Using the above as a guide, we have the following:

x² = (5√2)² + (5√2)²

Evaluate

x² = 100

Take the square roots

x = 10

Hence, the hypotenuse of the right triangle is (c) 10

In triangle ABC, A is a right angle, and mB = 45°. Find BC. If your answer is not an integer, leave it in simplest radical form.

Answers

This triangle is called a 45-45-90 triangle, and the side ratio for the sides opposite to the 45-45-90 degree angles respectively are 1-1-sqrt2

Now we know one side is 6 and its opposing the 45 degrees angle and BC is opposing the 90 degrees angle the ratio between the sides are 1:sqrt2

Therefore BC=6*sqrt2=6sqrt2

Thus B is the correct answer!
