A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of 12 centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of 58 bolts. The sample mean bolt length was 12.07 centimeters. The population standard deviation is known to be o=0.25 centimeters. what is the test statistic z? what is the p-value?

Answer:

x = 1.732051

Step-by-step explanation:

The fitted values when x² = 3 are x = 1.732 or x = - 1.732 .

To find the fitted value when x² = 3, we need to take the square root of both sides of the equation.

√(x²) = √3

Since x² is a positive value, the square root of x² will be the positive and negative square root of 3.

x = ±√3

Therefore, the fitted values when x² = 3 are x = √3 and x = -√3.

√3 = 1.732

x = 1.732 or x = - 1.732

The fitted values when x² = 3 are x = 1.732 or x = - 1.732 .

Answer: 140

Step-by-step explanation: N/7=20, so we have to isolate N. Hence, we multiply 7x7 because we are dividing by 7. We must multiply the other side too, so it is 140.

Answer:

N/7 = 20.

Cross multiply.

N x 1 = 20 x 7

N = 140.

Answer:

Step-by-step explanation:

AR⊥RS (tangent line is ⊥ to radius of the circle)

BS ⊥ RS (tangent line is ⊥ to radius of the circle.)

∴ AR and BS ⊥ to same line RS.

Hence either AR and BS are in same line  or parallel.

But they are radii of different circles.

∴ AR ║BS

The other dude is right, there is no point putting the same answer.

Answer:

QS = 12

Step-by-step explanation:

Hello!

We can see that QS is the sum of QR and RS, which is equal to 6x.

We can substitute the given values to solve for x, and then use that to find QS.

The value of x is 2. We can now find QS by substituting 2 for x in 6x.

QS = 12.

Equations go into one of two categories: identities or conditional equations. An identity holds true for each value of the variables. A conditional equation is valid only for certain values of the variables.

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

Finding the variables' values that cause the equality to be true is the first step in solving an equation with variables. The variables for which the equation must be solved are also known as the unknowns, and the unknowns' values that fulfill the equality are known as the equation's solutions. Equations can be categorized as either identities or conditional equations. For each value of the variables, an identity holds true. Only specific values of the variables make a conditional equation true.

Step-by-step explanation:

Area of bottom: 4 x 5 = 20

Area of left side: 15

Area of front: 4 x 3 = 12

Area of back: 12

Answer:

x = 15.4

Step-by-step explanation:

Reference angle = 33°

Opposite side reference angle = 10

Adjacent side = x

Therefore, we would apply the trigonometric function, TOA.

Thus:

Tan 33° = Opposite/Adjacent

Tan 33° = 10/x

Multiply both sides by x

x*Tan 33° = 10

Divide both sides by Tan 33°

x = 10/Tan 33°

x = 15.3986496

x = 15.4 (nearest tenth)

The angle at the center of the circle will be;

⇒ θ = 0.5 radian

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

A sector of a circle of radius 10 cm and has an area of 25 cm².

Now,

Since, We know that;

⇒ A = 1/2 r²θ

Where, A is area of circle , r is radius of circle and θ is the angle at the center of the circle.

Here, A sector of a circle of radius 10 cm and has an area of 25 cm².

Substitute all the given values, we get;

⇒ A = 1/2 r²θ

⇒ 25 = 1/2 × 10² × θ

⇒ 25 = 50 × θ

⇒ θ = 25 / 50

⇒ θ = 0.5 radian

Thus, The angle at the center of the circle = 0.5 radian

Answer:

1. 8x + 2y = 16

Step-by-step explanation:

3x - 12y = 10

12y = 3x - 10

y = 1/4 x - 5/6  .... slope: 1/4

perpendicular line slope: -4

8x + 2y= 16

2y = -8x + 16

y = -4x + 8  .... slope: -4

Numerical order can be used to organise a set of numbers. It is possible to use both increasing and decreasing ordering. Consider how a set of numbers would seem if they were organized in ascending order like 2, 55, 103, 256, and 802, for example. This can make sorting through a huge collection of numbers much easier.

Here,

Given : 2.5, -6, -3, 4, -2.2, 1/4, -1/2, 2 1/3

To put them according to ascending order :

So ,

negative terms are the smallest compare to positive terms as their values are lower than 0.

Answer:

Variable form: x=24 and x=1

Point form: (24,0) and (1,0)

Step-by-step explanation:

f(x) = x² - 25x + 24

0 = x² - 25x + 24

0 = (x-24)(x-1)

0 = x - 24 and x - 1 = 0

24 = x and x = 1

Therefore, the zeroes of the function are (24,0) and (1,0)
