6 + 10v – 8w = 62

Step-by-step explanation:

Given the expression

6 + 10v – 8w

as

substituting the values in the expression

6 + 10v – 8w = 6 + 10(4) - 8(-2)

                      = 6 + 40 + 16

                      = 62

Check the picture below.

so hmmm let's find the length of the slanted side, namely the hypotenuse of the triangle with sides of 9 and 7(half of 14).

\(\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ c^2=a^2+o^2\implies c=\sqrt{a^2 + o^2} \end{array} \qquad \begin{cases} c=hypotenuse\\ a=\stackrel{adjacent}{9}\\ o=\stackrel{opposite}{7} \end{cases} \\\\\\ c=\sqrt{ 9^2 + 7^2}\implies c=\sqrt{ 81 + 49 } \implies c=\sqrt{ 130 }\)

so now let's get the areas of those triangles and those rectangles.

\(\stackrel{\textit{two triangles}}{2\left[\cfrac{1}{2}(14)(9) \right]}~~ + ~~\stackrel{\textit{left and right rectangles}}{2(\sqrt{130})(20)}~~ + ~~\stackrel{\textit{bottom rectangle}}{(20)(14)} \\\\\\ 126+40\sqrt{130}+280\implies 406+40\sqrt{130} ~~ \approx ~~ \text{\LARGE 862.07}~cm^2\)

We are given a line segment AB with endpoints A(-1. -1) and B(7, 5).

The midpoint of this line segment AB is M with coordinates M(3, 2)

(a) Draw the perpendicular bisector of AB

A perpendicular bisector can be constructed using a compass.

This bisector will be perpendicular (exactly 90°) to the line AB and will pass through the midpoint of line AB.

The bisector drawn above is not drawn to the scale but rather just to give you an idea how it would look like.

The slope of this bisector line and the slope of the line AB will be negative reciprocal of each other.

Since we are given the endpoints of line AB, we can find its slope as

So, the slope of the line AB is 3/4.

Then the slope of the perpendicular bisector line will be

Therefore, the slope of the perpendicular bisector line is -4/3

(b) Write the equation of the line you drew in (a)

We are asked to find the equation of perpendicular bisector line

We already know its slope and also know that the bisector line passes through point M(3, 2)

Recall that the equation of the line in point-slope form is given by

Substitute the values of slope and the point into the above equation and solve for y

Therefore, the equation of the perpendicular bisector line is

Answer:

f = 8

Step-by-step explanation:

21 + 5f = 61

5f = 61 - 21

f = (61 - 21) / 5

f = 8

Answer:

f = 8

Step-by-step explanation:

"Sum" = addition

"Times" = multiplication

Write an equation to represent this scenario

21 + 5 * f = 61

Multiply 5 by f

21 + 5f = 61

Subtract 21 from both sides of the equation

5f = 40

Divide both sides of the equation by 5

f = 8

The original amount of the sale is $165

The given parameters are:

Bill after discount = $140

Discount = 15%

The original amount of the sale is calculated as:

Bill after discount = original amount * (1 - Discount)

So, we have:

140 = original amount * (1 - 15%)

This gives:

140 = original amount * 0.85

Divide by 0.85

Original amount = 165

Hence, the original amount of the sale is $165

Answer:

Grogg's dad is 22

Step-by-step explanation:

Let D = dad's current age

Let g = Grogg's current age

6(d - 7) = g - 7 → 6d - 42 = g - 7 → 6d -35 = g

4(d - 3) = g - 3 → 4d -12 = g - 3 → 4d -9 = g

Set the two equations equal to each other and solve for d

6d - 35 = 4d - 9  Subtract 4d from both sides

2d -35 = -9  Add 35 to both sides

2d = 44  Divide both sides by 2

d = 22

Helping in the name of Jesus.

Answer:

Step-by-step explanation:

d = current dad age

g = current grogg age

d-7 = 6(g-7)

d-3 = 4(g-3)

Let's solve the first equation first:

Add 7 to both sides: d - 7 +7 = 6g - 42 + 7 so d = 6g - 35

Substitude d = 6g - 35 for d in d - 3 = 4g - 12

(6g-35)-3 = 4g-12 = 6g-38 = 4g-12

Subtract 4g from both sides: 2g - 38 = -12

Add 38 to both sides: 2g = 26

Easy: g = 13

And now substitude g in for any equations.

d-3 = 52-12

d = 43

Answer:

Amount required = 2,217,600

Step-by-step explanation:

Dimensions of the rooms are as follows;

Room 1; 9 feet × 12 feet

Room 2; 14 ft × 16 ft

Room 3; 12 ft × 14 ft

Perimeter of rooms;

P1 = 2(9 + 12) = 42 ft

P2 = 2(14 + 16) = 60 ft

P3 = 2(12 + 14) = 52 ft

Total perimeter; P = 42 + 60 + 52 = 154 ft

Height is 90 ft.

Thus, total area is;

A = 154 × 90

A = 13860 ft²

Rate of painting is 160 per Sq.ft.

Thus amount to paint entire area = 160 × 13860 = 2217600

Let w be the weight on point s. Since the sum of the weights is 1, the weight on point t is 0.625, we can write:

w + 0.625 = 1

Subtracting 0.625 from both sides, we get:

w = 1 - 0.625 = 0.375

Therefore, the weight on point s is 0.375.

Answer:

535,095 different samples of size six that contain exactly 2 defective parts.

0.0337 = 3.37% probability that a sample contains exactly 2 defective parts.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

As the order of the parts is not important, the combinations formula is used to solve this question.

Combinations formula:

\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

How many different samples are there of size six that contain exactly 2 defective parts?

2 defective from a set of 3, and 4 non-defective from a set of 47. So

\(D = C_{3,2}*C_{47,4} = \frac{3!}{2!1!}*\frac{47!}{4!43!} = 535095\)

535,095 different samples of size six that contain exactly 2 defective parts.

What is the probability that a sample contains exactly 2 defective parts?

The total number of samples is:

\(T = C_{50,6} = \frac{50!}{6!44!} = 15890700\)

Then...

\(p = \frac{D}{T} = \frac{535095}{15890700} = 0.0337\)

0.0337 = 3.37% probability that a sample contains exactly 2 defective parts.

On a number line, the value C that represents the square root of 24 would be located between 6 and 7, although it would be closer to 6. Option C is correct

A horizontal line with number increments that are uniformly spaced apart is called a number line.

The answers to the number on the line will be determined by the numbers that are already on the line.

The inquiry that follows the number explains how it will be used, such as by charting a spot in the data.

Number lines are extremely versatile manipulatives that can be used for a wide variety of mathematical operations, including finding numbers, comparing numbers, working with fractions and mixed numbers, decimals, integers, absolute value, addition, subtraction, inequalities, multiples, and common denominators, and much more.

Find the point on the number line that corresponds to the value -37 by doing the following:

As is well knowledge, the value of 37 is 6.082.

If we round the number up to the next whole number, we get 6.

Therefore, the answer is somewhere between 6 and 7, although probably closer to 6.

The mean absolute deviation (MAD) for the given data is 1/20. This means that, on average, each data point in the set differs from the mean by 1/20.

To find the mean absolute deviation (MAD) of a set of data, we need to calculate the average difference between each data point and the mean of the data set. Here's how we can calculate it for the given data:

Step 1: Find the mean (average) of the data set.

Mean = (1/4 + 5/8 + 3/8 + 3/4 + 1/2) / 5 = 2/5

Step 2: Calculate the difference between each data point and the mean.

Differences: |1/4 - 2/5|, |5/8 - 2/5|, |3/8 - 2/5|, |3/4 - 2/5|, |1/2 - 2/5|

Step 3: Calculate the absolute value of each difference.

Absolute Differences: 1/20, 1/40, 1/40, 1/20, 1/10

Step 4: Find the average of the absolute differences.

MAD = (1/20 + 1/40 + 1/40 + 1/20 + 1/10) / 5 = 1/20

The MAD provides a measure of the average amount of variation or dispersion in the data set. In this case, a MAD of 1/20 indicates that the data points are relatively close to the mean, with most values falling within 1/20 of the mean value.

The greatest inference we can draw from the data presented and the dot plot, however, is that there is proof indicating that Drug A is much more likely than Drug B to increase levels of human growth hormone.

the process of developing; progressive expansion; the act or activity of growing.

According to the provided dot plot, there appears to be a considerable variance in both medications' capacities to raise levels of human growth hormone. There is little crossover in the pieces of data for the two medicines, and the mean rise for Drug A is obviously greater than the average rise for Drug B.

We would need to do a formalized hypothesis test, which might involve a t-test, and generate a p-value to establish to see if this variance has statistical significance. We could conclude that the variation in averages is statistically significant if the p-value is less than a predetermined significance criterion (for example, 0.05).

The most important conclusion that can be made from the data and dot plot is the existence of evidence that suggests Drug A is much more probable that Drug B to enhance levels of growth hormone in humans. Further statistical analysis would be required to confirm the relevance of this divergence.

B) The area would be:

So, the area would be 1/8bh [Since the values of b & h are unknown they remain as variables].

***Explanation***

We can see that at stage 2 each base if each triangle is equivalent to one-half of the triangle at stage 1. From this, we can see then, that "the middle" of the triangle would be given by the interception point of both bases at stage 2, and since the height of the triangle at stage 1 has a measurement of "h" [We name h the height of the triangle] then, the height of each individual triangle at stage 2, will also be one-half of the original.
