Answer:

Step-by-step explanation:

The height of the cone base diameter of 8 cm and the slant height is 8 cm is 4√3 cm.

Given is a cone with base diameter of 8 cm and the slant height is 8 cm, we need to find the height of the cone by using Pythagorean Theorem.

To find the height of the cone using the Pythagorean Theorem, we can consider the slant height as the hypotenuse, the radius as one side, and the height as the other side.

Let's denote the radius of the cone as r and the height of the cone as h.

According to the given information, the base diameter of the cone is 8 cm, which means the radius is half of that, so r = 8 cm / 2 = 4 cm.

Now, using the Pythagorean Theorem, we have:

r² + h² = slant height²

Substituting the given values, we get:

4² + h² = 8²

16 + h² = 64

h² = 64 - 16

h² = 48

Taking the square root of both sides, we find:

h = √48

Simplifying the square root, we get:

h = √(16 x 3)

h = √16 x √3

h = 4√3 cm

Therefore, the height of the cone is 4√3 cm.

Answer:

Length = 23 feet

Step-by-step explanation:

Formula to get the area of a Rectangle

Area = Length x width ( Length x breadth)

if Area = 69 feet and Width = 3 feet Length = x

Area = Length x Width

substitute the values

69 square feet = X feet x 3 feet

69 = 3x

69/3 = 3x/3

23 = X

Length = 23 feet

Proof: 23 X 3 = 69 ✓

Answer:

Any number 5 and below

Step-by-step explanation:

We are given the expression that the difference between a number and 3 is no more than 2. Break down the expression and spot the key word of "difference," therefore meaning that the unknown number "x" and 3 is equal or less than 2. We can create the algebraic expression of x - 3, now since the answer must equal 2 or below 2, we can create the inequality :

x - 3 ≤ 2

Now the only numbers that are allowed to be inputted here is 5 and below.

The solution to the inequality "the difference between a number and 3 is no more than 2" is x ≤ 5 or x ≥ 1.

Let us denote the number as "x," we can express the given statement as an inequality:

|x - 3| ≤ 2

This inequality states that the absolute value of the difference between x and 3 is less than or equal to 2.

If x - 3 ≥ 0 (x ≥ 3)

In this case, the absolute value can be removed:

x - 3 ≤ 2

x ≤ 2 + 3

x ≤ 5

and if x - 3 < 0 (x < 3)

The absolute value becomes negative:

-(x - 3) ≤ 2

x + 3 ≤ 2

x ≤ 2 - 3

x ≤ -1

x ≥ 1

Combining the results from both cases, we have:

x ≤ 5 or x ≥ 1

Therefore, the solution to the inequality "the difference between a number and 3 is no more than 2" is x ≤ 5 or x ≥ 1.

Step-by-step explanation:

24 dividing by 3 equals 8.

The number of vanilla cupcakes at the party will be 8.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that at a party, the ratio of chocolate cupcakes to vanilla cupcakes is 4 to 3. If there are 24 chocolate cupcakes.

The number of cupcakes will be calculated as:-

4 / 3 = 24 / V

V = ( 24 x 3 ) / 4

V = 18

Hence, the quantity of vanilla cups is 18.

Answer:

5:20

Step-by-step explanation:

When working with the min hand

Starting from 12, each number of a clock adds an additional 5 mins until you reach the 12, where it starts at 0 again. So

1 = :05

2= :10

3 =:15

4 = :20

...and so on

When its 5:00, the hour hand is on the 5. As it moves towards 6:00, the hour hand will start to gradually get pulled towards the 6 until it becomes 6:00, where it will finally reach the 6.

Answer:

The average rate of change is 2.

Step-by-step explanation:

We are given the function:

[tex]g(x)=-x^2+x+5[/tex]

And we want to find the average rate of change over the interval:

[tex]-4\leq x\leq 3[/tex]

The average rate of change is synonymous with the slope. So, we will evaluate the function at its endpoints and find the slope between them.

Our first endpoint is given by:

[tex]g(-4)=-(-4)^2+(-4)+5=-15[/tex]

And our second endpoint is given by:

[tex]g(3)=-(3)^2+(3)+5=-1[/tex]

This gives us two points (-4, -15) and (3, -1). The average rate of change will be the slope between them. Thus:

[tex]\displaystyle ARC=\frac{-1-(-15)}{3-(-4)}=\frac{14}{7}=2[/tex]

The average rate of change is 2.

Answer:

slope measures the rate of change in the dependent variable as the independent variable changes

The 3rd and 6th

Step-by-step explanation:

Make a system of equations, try to solve, and then see which statements apply.

let x be the cost of a DVD and y be the cost of a video game

Then you would have:

2x + y = 12

4x + 2y = 24

from turning the words into equations.

Now, solve:

first, multiply the first equation by 2

2x + y = 12 --> 4x + 2y = 24

Then, subtract the two equations:

4x + 2y = 24

- (4x + 2y = 24)

0 = 0

Since you have a number = a number, there are infinite solutions.

0.367 = 36.7% probability that the student gets fewer than 2 questions correct

Step-by-step explanation:

For each question, there are only two possible outcomes. Either he guesses the correct answer, or he does not. The probability of guessing the correct answer on a question is independent of any other question. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

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

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

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

8 questions on it

This means that [tex]n = 8[/tex]

4 choices.

One of them is correct, which means that [tex]\pi = \frac{1}{4} = 0.25[/tex]

What is the probability that the student gets fewer than 2 questions correct?

This is

[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]

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

[tex]P(X = 0) = C_{8,0}.(0.25)^{0}.(0.75)^{8} = 0.1[/tex]

[tex]P(X = 1) = C_{8,1}.(0.25)^{1}.(0.75)^{7} = 0.267[/tex]

[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.1 + 0.267 = 0.367[/tex]

0.367 = 36.7% probability that the student gets fewer than 2 questions correct
