Answer:

0.96

Step-by-step explanation:

Total samples of window = 10smaples

Total seal break = 4% of 10

Total seal break = 0.04 * 10

Total seal break = 0.4

THis means that no seal will be break on 96% of the window i.e 9.6 windows

The probability that, in a sample of 10 windows, no seals will break is expressed

as;

Pr(no seal will break) = 9.6/10

Pr(no seal will break)  = 0.96

Hence the probability that no seals will break is 0.96

Answer:-16x+22y

Step-by-step explanation:

Distribute the negative 5, then the -4

add and subtract like termd

Answer:

\(-16x+22y\)  is your answer!

Step-by-step explanation:

Simplifying

-5(8x + -2y) + -4(-6x + -3y)

(8x * -5 + -2y * -5) + -4(-6x + -3y)

(-40x + 10y) + -4(-6x + -3y)

-40x + 10y + (-6x * -4 + -3y * -4)

-40x + 10y + (24x + 12y)

Reorder the terms:

-40x + 24x + 10y + 12y

Combine like terms: -40x + 24x = -16x

-16x + 10y + 12y

Combine like terms: 10y + 12y = 22y

-16x + 22y

Answer:

6/5

Step-by-step explanation:

2/5*3=2/5*3/1=6/5

Answer:

\(\frac{6}{5}\) or \(1\frac{1}{5}\)

Step-by-step explanation:

\(\frac{2}{5} *3\)

3 can be rewritten as 3/1

\(=\frac{2}{5}*\frac{3}{1}\)

Multiply the numerators and denominators

\(2*3=6\\5*1=5\)

\(= \frac{6}{5}\)

You can also change this into a mixed number by dividing the numerator by the denominator and writing the remainder as the numerator:

\(= 1\frac{1}{5}\)

Jayden needs no fewer than 90 tiles to cover the entire floor of his bathroom during the renovation. This means that he needs at least 90 tiles to complete the project.

It is important for Jayden to accurately measure the size of his bathroom floor and calculate the number of tiles he will need to ensure that he has enough to cover the entire area. If he does not have enough tiles, he may need to purchase additional tiles to complete the project. It is also important for Jayden to consider the size and shape of the tiles he will be using, as this will impact the number of tiles he will need to cover the floor. By accurately measuring and calculating the number of tiles needed, Jayden can ensure that he has enough materials to complete the renovation of his bathroom floor.

The required expression would be 12p - 33q + 104 which is equivalent form of 12(p + 5) − 11(3q + 4).

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

We have been given the expression:

12(p + 5) − 11(3q + 4)

Apply the distributive property of multiplication,

12p + 12 × 5 − 11 × 3q + 11 × 4

12p + 60 - 33q + 44

Rearrange the terms likewise and apply the arithmetic operation,

12p - 33q + 60  + 44

12p - 33q + 104

Therefore, required expression would be 12p - 33q + 104 which is equivalent form of 12(p + 5) − 11(3q + 4).

Answer:

Step-by-step explanation:

The correct answer is D. setne 23 47. Based on the provided information, I understand that you have a comparison function in C code and its corresponding assembly code. You are asked to fill in the blanks by selecting the appropriate instructions based on the given values of a and b and the status flags SF, OF, ZF, and CF. Let's go through the options:

A. setg 47 23: This option is incorrect because setg is used to set a byte to 1 if the Greater flag (ZF=0 and SF=OF) is set, but the given values of a and b are 47 and 23, respectively, so it does not satisfy the condition for setg to be set.

B. setl 23 47: This option is incorrect because setl is used to set a byte to 1 if the Less flag (SF≠OF) is set, but the given values of a and b are 23 and 47, respectively, so it does not satisfy the condition for setl to be set.

C. sete 23 23: This option is incorrect because sete is used to set a byte to 1 if the Zero flag (ZF=1) is set, but the given values of a and b are 23 and 23, respectively, so it does not satisfy the condition for sete to be set.

D. setne 23 47: This option is correct. setne is used to set a byte to 1 if the Zero flag (ZF=0) is not set, which means the values of a and b are not equal. In this case, the given values of a and b are 23 and 47, respectively, so they are not equal, and setne should be used.

Therefore, the correct answer is D. setne 23 47

The coordinates of the vertices of the dilated image, ΔR'S'T' include the following: A. R' (4, 12), S' (12, 12), T' (8, 4).

In Mathematics and Geometry, a dilation simply refers to a type of transformation which typically changes the size of a geometric object, but not its shape.

This ultimately implies that, the size of the geometric shape would be increased (stretched or enlarged) or decreased (compressed or reduced) based on the scale factor applied.

Next, we would apply a dilation to the coordinates of the pre-image by using a scale factor of 4 centered at the origin as follows:

Ordered pair R (1, 3) → Ordered pair R' (1 × 4, 3 × 4) = R' (4, 12).

Ordered pair S (3, 3) → Ordered pair S' (3 × 4, 3 × 4) = S' (12, 12).

Ordered pair T (2, 1) → Ordered pair T' (2 × 4, 1 × 4) = T' (8, 4).

Answer: $657.53

Step-by-step explanation:

Circumference of a circle = πd

But in this case, it's a semi circle, so the circumference will be:

= πd/2

= (3.142 × 31) / 2

= 97.402/2

= 48.701

Then, the total amount of the fencing will be:

= 48.701 + 31

= 79.701

Then, the fencing cost will be:

= 79.701 × $8.25

= $657.53

The equation for the line tangent to the circle \(\(x^2 + y^2 = 169\)\) at the point \(\((-5, 12)\)\) is \(\(x + 5y = 13\)\).

To find the equation of the tangent line to the circle at a given point, we need to determine the slope of the tangent line and its point of tangency. The slope of the tangent line is equal to the negative reciprocal of the derivative of the circle's equation with respect to x.

Differentiating the equation \(\(x^2 + y^2 = 169\)\) with respect to x, we get \(\(2x + 2y \frac{{dy}}{{dx}} = 0\)\). Rearranging this equation, we find \(\(\frac{{dy}}{{dx}} = -\frac{{x}}{{y}}\)\).

Substituting the coordinates of the given point (-5, 12) into the derivative, we have \(\(\frac{{dy}}{{dx}} = -\frac{{-5}}{{12}} = \frac{{5}}{{12}}\)\).

Since the tangent line has the same slope as the derivative at the point of tangency, the slope of the tangent line is \(\(\frac{{5}}{{12}}\)\).

Using the point-slope form of a line, \(\(y - y_1 = m(x - x_1)\)\), where \(\((x_1, y_1)\)\) is the given point, we substitute \(\((-5, 12)\)\) and the slope \(\(\frac{{5}}{{12}}\)\) to obtain \(\(y - 12 = \frac{{5}}{{12}}(x + 5)\)\).

Simplifying this equation, we get \(\(x + 5y = 13\)\), which is the equation of the tangent line to the circle at the point \(\((-5, 12)\)\).
