Can someone help me find x and y?

Step-by-step explanation:

1 f(x) = ax (x − a)² + 1

Take the derivative

f'(x) = d/dx ( a x( x -a) ²+1

Use differentiation rules

f' x = ax2 x-a +0

Simplify

= f'(x)=2ax-2a²

answer

Answer: The value of f/5 is 4.

Step-by-step explanation:  This question can be solved by using substituting the value of f( which is 20) in the earlier given expression ( which is f/5).

Here are the steps to solve this question:-

Step 1. Expression = f/5 ( according to the question)

Step 2. Value of f=20 ( according to the question)

Step 3. Using the value of f in step 2 in the equation given in step 1,

                        f/5=20/5

                         f/5=4

Thus, the value of expression f/5 is 4.

The experimental probability of an odd number other than 9 being generated is 0.38.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

According to the probability formula, the probability of an event occurring, or P(E), is equal to the proportion of positive outcomes to all outcomes. P(E) is defined mathematically as favorable outcomes divided by total outcomes.

Given Data

A random number generator is used to create a list of 150 single-digit numbers. Of those 150 numbers, 72 are odd and 78 are even. The number 9 was generated 15 times.

Total numbers generated = 150

Odd numbers = 72

Even numbers = 78

Generation of number 9 = 15

Number of odd numbers except 9 itself

= 72 -15

= 57

Probability = [tex]\frac{Odd numbers except 9 itself}{total munbers}[/tex]

Probability = [tex]\frac{57}{150}[/tex]

Probability = 0.38

The experimental probability of an odd number other than 9 being generated is 0.38.

The number of terms of the second arithmetic progression is 46.

The two arithmetic progression have the same first and last terms.

The first arithmetic progression has 21 terms with a common difference of 9.

The second arithmetic progression have common difference of 4.

Therefore,

using the first arithmetic progression,

a + (n - 1)d = nth term

a + 20(9) = last term

last term = a + 180

using the second arithmetic progression,

a + (n - 1)d = nth term

They have the same last and first term,

Hence,

a + 180 = a + (n - 1)4

a + 180 = a + 4n - 4

180 + 4 = 4n

184 = 4n

n = 184 / 4

Answer:

B) To make a right triangle in the center, the area of the smaller two square must add to equal the area of the largest square

Step-by-step explanation:

1) add the area of the two smaller squares together

f^2= 9

g^2 = 16

9+16=25

2) compare the sum of the two squares to the larger square (the hypotonus)

h^2= 25 so, f^2 + g^2 = h^2

3) The area of the smaller squares is equal to the area of the larger square, therefore b is the correct answer.

The layer of dirt would be between 3 and 4 yards and precisely 3.6458 yards.

Given the volume of the lot is 7000 cubic yards.

After spreading to an even layer

The dimension is 30 yards and 64 yards

The volume of the lot can be given as Length x Width x Depth

Let us say the depth of the lot is x

Which means

30 x 64 x X = 7000

1920 x X = 7000

X = 3.6458

Hence the depth of the lot is 3.6458 which is between 3 and 4.

Answer: The arrow is pointing to 76.5.

Step-by-step explanation: It's pointing to 76.5 because there are 10 spaces between 75 and 80 so in that case, each line is .5, and since it's on the third line that means it is 1.5 more than 75 so 76.5.

Answer:

C) The arrow points to 76.5.

Step-by-step explanation:

The number line is divided into 10 parts equally.

We can find out the distance between each point by taking the difference between the largest and smallest number on the number line and dividing the difference by 10.

80 - 75 = 5

5/10 = .5

So, the distance between each number/mark on the line is .5

Now, we can label each point by adding .5 to each mark as we go. Then, we'd get this.

*see attachment below

Since the number line constructed here has all the values, we can now tell which value the arrow is pointing to.

The answer is therefore 76.5.

You must explicitly state that the null hypothesis is demonstrated to be true in cases where there is insufficient evidence to disprove it.

A statistical hypothesis known as a null hypothesis asserts that no statistical significance can be found in a collection of provided observations. Using sample data, hypothesis testing is performed to judge a theory's veracity. It is sometimes referred to as just "the null," and its symbol is H₀

Even though we are unable to rule out the null hypothesis, this does not always imply that it is accurate. The reason for this is that a hypothesis test cannot tell which hypothesis is true or even which is more likely. It just evaluates whether there is sufficient evidence to disprove the null hypothesis.

the length of the rectangle is 10 cm and the width of the rectangle is 11 cm.

We are given that the length and the width of a rectangle are consecutive integers.

Let the length be x

Width = x + 1

Now, we are also given that perimeter is:

P = 42 cm

We know the formula for perimeter of a rectangle is:

P = 2( l + w)

Substituting the values in the formula, we get that:

42 = 2( x + x + 1)

42 = 2 (2 x + 1)

42 = 4 x + 2

4 x = 40

x = 40 / 4

x = 10

a. The equation of the perimeter is x + x + x + 2x + 2x = 42. Option A

b. x = 6 centimeters

c. The lengths are 6 centimeters , 6 centimeters , 6 centimeters  , 12 centimeters  and 12 centimeters respectively.

It is important to note that the formula for calculating the perimeter of a pentagon is expressed as;

Perimeter = 5a

Where: 'a' represents the length of one of its side

From the information given, we have that the perimeter of the geometrical figure is the sum of its sides.

Given the sides;

x , x , x, 2x , 2x

Now, substitute the values into the formula for perimeter

x + x + x + 2x + 2x = 42

collect like terms and add them

7x = 42

Now, make 'x' the subject of formula by dividing both sides by the coefficient of the variable 'x'

We have;

7x/7 == 42/7

x = 6 centimeters

But the length of the sides is determined by substituting the value of x as 6

x = 6 centimeters

x = 6 centimeters

x = 6 centimeters

2x = 2(6) = 12 centimeters

2x = 2(6) = 12 centimeters

The inequality representing the shaded region is given by 2y - x < 4.

For the given question, the graph is shown,

Consider two coordinates from the graph and find the slope using them.

(x₁, y₁) = (0, 2)

(x₂, y₂) = (4, 4)

slope m = (y₂ - y₁)/(x₂ - x₁)

Put the values.

m = (4 - 2)/(4 - 0)

m = 1/2

Put the value of slope in the equation of line in slope intercept form.

y - y₁ = m(x - x₁)

Put the values;

y - 2 = 1/2(x - 0)

Simplifying;

2y - 4 = x

Parallel lines have the same slope, hence the slope of 3y -mx +3= 0 is also equal to 1.

The dimension of the rectangular box are 9 inches, 8 inches and 3 inches.

The volume of the rectangular box can be expressed as follows:

volume of the rectangular box = l w h

Therefore,

w = x inches

l = 3x

h = 3x - 1

volume of the rectangular box = 72x
