When we reject the null hypothesis and the null hypothesis is true, we have made a Type I error.

In statistical hypothesis testing, the null hypothesis is a statement that represents the anticipated or "normal" outcome of a specific experiment. Unless there is evidence to the contrary, the null hypothesis, which is generally represented by the symbol "H0," is taken to be true.

A Type I mistake, sometimes known as a "false positive," arises when the null hypothesis is correct but is rejected based on the evidence. Applying a statistical test with a strong significance level increases the likelihood of rejecting the null hypothesis even when it is correct, which frequently leads to this mistake.

Making a Type I error can have major repercussions since it can result in judgments being formed based on flawed information and wrong inferences being drawn.

Answer:

y = [tex]x^2+2x+12[/tex] (x and y intercepts under "Step-by-step explanation" section)

Step-by-step explanation:

We can start by finding the vertex form and then expand it to the standard form.

The vertex form of the quadratic equation is

[tex]y=a(x-h)^2+k[/tex], where a is a constant and (h, k) is the vertex.

By plugging in 1 for a, -1 for h, and 11 for k, we have:

[tex]y=1(x-(-1))^2+11\\y=(x+1)^2+11[/tex]

Now we simply expand this vertex form to get the standard form:

[tex]y = (x+1)^2+11\\y=(x+1)(x+1)+11\\y=x^2+x+x+1+11\\y=x^2+2x+12[/tex]

We can find the x and y-intercepts using the vertex form.

To find the x-intercept, we plug in 0 for y:

[tex]0=(x+1)^2+11\\-11=(x+1)^2\\\sqrt{-11}=x+1;-\sqrt{11}=x+1\\ x_{intercepts}:(-1+\sqrt{-11}, 0); (-1-\sqrt{-11})[/tex]

The x-intercepts are non-real answers, so the quadratic equation never intersects the x-axis.

To find the y-intercept, we plug in 0 for x:

[tex]y=(0+1)^2+11\\y=1^2+11\\y_{intercept} =(0,12)[/tex]

The value based on the given equation is 22.5

What is an equation?

In arithmetic,an equation may be a formula that expresses the equality of 2 expressions, by connecting them with the sign =.

Main body:

According to given info.

u + t = 5        ------(1)

u - t  = 2        ------(2)

adding equation 1, 2  ;we get      

2u = 7

u = 7/2

using value of u in any equation,

7/2 - t = 2

t = 3.5 - 2

t = 1.5

we need to find value of

(u-t) (u²-1²)

(3.5 - 1.5) (3.5² -1²)

2*(12.25 - 1)

2*(11.25)

22.5

Considering all the option and the question, We cannot determine anything about the angle is the right answer.

An angle is a geometric shape that is formed by two rays that share a common endpoint, called the vertex.

The vertex of an angle is the common endpoint of the two rays that form the angle. The vertex is also sometimes called the "corner" of the angle.

It is not possible to determine whether the angle of the ramp will decrease or increase without more information. The angle of the ramp is determined by the slope of the ramp, which is the change in height divided by the change in distance. If the ramp starts closer to the step, it will have a different slope, and therefore a different angle, than if it starts 5 feet away from the base of the step.

Whole numbers are a collection of positive integers and zero that do not contain any fractions.

                       It is denoted by the letter "W," and its corresponding set of numbers are "0," "1, 2, 3,,","5,,"6,,"7,","8,"..."

It is given that Mark, Taylor, & Brian's ages are consecutive whole numbers, Mark is the youngest, and Brian is the oldest and the sum of their ages is 111.

Suppose the age of mark is x as a result the age of Taylor and brian will be x + 1 and x + 2 respectively.

From the given condition the sum of their ages is 111,

⇒x + x + 1 + x + 2 = 111

⇒3x + 3 = 111

⇒3x = 111 - 3

⇒3x = 108

Explanation:

Angle R = angle A = 41 since both angles involve a single arc marking.

Angle S = angle B = 74, both involve a double arc

For any triangle, the inside angles always add to 180 degrees.

R+S+T = 180

41+74+T = 180

115+T = 180

T = 180-115

T = 65

The product of the expression [3 + 1/10] (-6 x 7 / 12) is -10 + (17 / 20) = negative 10 and 17 over 20.

Multiplication is mathematical arithmetic operation. It is also a process of adding same types of expression to some number of times.

Example - 2 × 3 means 2 is added three times or 3 is added 2 times.

Given that the expression { 3 + (1/10) } {-6 x (7 / 12) }

Simplifying the expression using PEMDAS,

{ 3 + (1/10) } {-6 x (7 / 12) }

= ( 31 / 10 ) × ( -7 / 2 )

= - 217 / 20

= -10 + (17 / 20)

= negative 10 and 17 over 20

Create a square on paper by using a pencil. Tw dimensions make it up. A shape's area on paper is the space it takes up.

Imagine that your square is made up of smaller unit squares.

The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.

To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.

According to our question-

V' equals (4 pi x r' x r'2) (4 pi x (.9 3) x r2 x r')

This equation expresses how quickly the rind volume changes over time.

As stated in the issue, r' = 2.

Additionally, the radius will be r = 2 * 5 = 10 after 5 weeks.

V' equals (4 pi x 102 x 2) (Pi x (.93) x 10 x 2) = -

The value of x for the given Right angled triangle is x= 8√3. So, option c is correct.

90 degrees or a straight angle is always one angle. The hypotenuse is the side that has an angle of 90° on it. Always, the hypotenuse is the longest side. The remaining two inner angles add up to a total of 90°. The bases and perpendiculars are the other two sides that are close to the right angle.

A right triangle is a triangle with one of the internal angles at 90 degrees. The hypotenuse, the side of the right triangle that is opposite the right angle and is also its longest side, and the height and base are the two arms of the right angle.

Given,

∴ Any point lies on the line CD equidistant from A and B

- If point E lies on the line CD
