A man is trying to fit a washing machine into a corner of a four-sided room. He knows that all the walls are perfectly straight, but he is not sure if the corner is an exact right angle. If the other three corners are all 90° angles, what is the measure of the missing corner?

Population parameters are used to estimate sample statistics, and this is true.

Population parameters are used to describe the characteristics of a population, such as the mean, median, and standard deviation, and are used to make inferences about a population. Sample statistics, on the other hand, are used to describe the characteristics of a sample of a population. For example, a sample statistic could be the mean of a sample of people's heights.

To estimate sample statistics, population parameters must first be known. For example, the sample mean can be estimated using the population mean. If the population means are unknown, then the sample means can be estimated using the sample mean.

In conclusion, population parameters are used to estimate sample statistics, and this is true. Population parameters provide useful information about a population that can be used to make inferences about a sample. Knowing the population parameters allows researchers to make more accurate estimates of sample statistics, which in turn can be used to make more reliable inferences about a population.

Residual Plot A indicates that the linear model is not appropriate because the fanned pattern shows that the model's predicting power decreases as the values of the explanatory variable increases. Residual Plot B indicates that the linear model is appropriate because the scattered residuals suggest a linear relationship.

Residual Plot A shows a fanned pattern which indicates that the linear model is not appropriate. This means that the model's predicting power decreases as the values of the explanatory variable increases. This suggests that the relationship between the dependent and independent variables is not linear and a different model may be necessary. Residual Plot B, on the other hand, shows a scattered pattern which suggests that the linear model is appropriate. The scattered pattern indicates that the data points are randomly distributed, which is a sign of a linear relationship. This indicates that the linear model is an appropriate fit for the data.

Solution a needed 70 ounces and solution b needed 50 ounces

What does "1 ounce" mean?

One ounce weighs 437.5 grains or 28.349 grams and is a sixteenth of a pound (avoirdupois) of weight.

One ounce, abbreviated "oz," equals 480 grains, or 31.103 grams, and is one-twelfth of a Troy or Apothecaries' pound in weight. abbreviation for fluid ounce. a tiny amount or percentage.

So, let x=the of ounces of the 50% acid solution. The total volume after both are mixed is 100 ounces so the amount of the 20% solution will be 120-X. The equation will therefore be:

50% * x + 20% * (100-x) = 41% * 100

Dropping the ‘%’ we get

50x + 2000 - 20x = 4100

30x = 2100

x = 2100/30 = 70

Hence 70 ounces will be needed

Answer:

It is 44

Step-by-step explanation:

The perimeter of the paralllelogram given is: 44 units.

Perimeter = 2(a + b), where a and b are the legs of the sides adjacent to each other.

Given the following:

Since opposite sides of a parallelogram are equal, therefore:

4y - 2 = 2y + 6

4y - 2y = 2 + 6

2y = 8

y = 4

2x + 2 = 3x - 1

2x - 3x = -2 - 1

-x = -3

x = 3

Perimeter of the paralllelogram = 2(AB + AD) = 2(4y - 2 + 3x - 1)

Plug in the values of x and y

Perimeter of the paralllelogram = 2(4(4) - 2 + 3(3) - 1)

Perimeter of the paralllelogram = 2(16 - 2 + 9 - 1)

Perimeter of the paralllelogram = 44 units.

Given:

Two angles are Complementary.

One angle measures (2x-16) degrees.

The other measures (x +1) degrees.

To find:

The value of the larger angle.

Solution:

Let,

\(\angle 1=(2x-16)^\circ\)

\(\angle 2=(x+1)^\circ\)

We know that, sum of two complementary angles is 90 degrees. Since, given angles are complementary angles, therefore

\(\angle 1+\angle 2=90^\circ\)

\((2x-16)^\circ+(x+1)^\circ=90^\circ\)

\((3x-15)^\circ=90^\circ\)

Now,

\(3x-15=90\)

\(3x=90+15\)

\(3x=105\)

Divide both sides by 3.

\(x=35\)

The value of x is 35.

\(\angle 1=(2(35)-16)^\circ\)

\(\angle 1=(70-16)^\circ\)

\(\angle 1=(54)^\circ\)

And,

\(\angle 2=(35+1)^\circ\)

\(\angle 2=(36)^\circ\)

Therefore, the value of the larger angle is 54 degrees.

Two lines are parallel if:

Where:

m1 = slope of the line 1

m2 = slope of the line 2

Rewrite the equations in the slope intercept form:

From the previous equation we can conclude that the slope is m = 3, since the line we need to find is parallel to this one, we can conclude that the slope of the line we are trying to find is also m = 3

For the other equation:

From this line we can conclude that the y-intercept is b = 9, since the line we are trying to find has the same y-intercept, we can conclude that its y-intercept is also b = 9. Therefore, the equation of the line is:

Step-by-step explanation:

Yards are 36 inches and feet are 12

move x to the other side

-5y=-2x+4

times -1/5 on both sides

y=2/5x+8/5

therefore, slope is 2/5

The requried slope of the given line 2x−5y=4 is m = 2/5.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

here,
Given the equation of the line,
2x - 5y = 4

Transform the above equation in the slope-intercept form as, y = mx +c
-5y = 4 - 2x
y = 2x/5 - 4/5

Comparing the above equation with the standard equation of the line,
m = 2/5

Thus, the requried slope of the given line 2x−5y=4 is m = 2/5.

The slope of the line in 1. is -3/4 and the slope of 2. is 9/10.

Understanding what slope is is among the most crucial things to know about lines. The line's slope, also referred to as rise over run, is how "steep" it is. By dividing the difference between the y-values at two points by the difference between the x-values, we can determine slope. Understanding how to interpret graphs and create equations is necessary in order to comprehend the significance of the definition of slope.

Answer: Because they're based off the power of 10.

Step-by-step explanation:

I think the answer is correct because, to make 15.6 to 1560 you just need to multiply by 100, and to get 3.12 to 312 all you have to do is multiply by 100. So if you divided 1560 and 312 which is 5, all you have to do is divide by 100 and you get the same answer thats why its basically considered the same because of the power of tens.

The angle ∠CEA in the circle is 26 degrees.

If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

Therefore, using the chord intersection theorem let's find the angle ∠CEA.

Therefore,

∠CEA = 1 / 2 (87 - 35)

∠CEA = 1 / 2 (52)
