In Euclidean geometry, an angle is the figure formed by two rays, known as the sides of the angle, that have a common termination, known as the vertex of the angle. Angles formed by two rays are located in the plane that contains the rays.

An angle in Plane Geometry is a figure formed by two rays or lines that share a common endpoint. "Angle" comes from the Latin word "angulus," which means "corner." The two rays are referred to as the sides of an angle, while the common endpoint is referred to as the vertex.

In Euclidean geometry, an angle is the figure formed by two rays known as the sides.

The total number of oranges present in the bag was 21.

For the stated question.

Let the total number of oranges in the bag be 'x'.

Total stale oranges = 7.

Thus,

Probability (first orange is stale) = Total stale oranges/ Total oranges.

Probability (first orange is stale) = 7/x

Probability (second orange is stale) = 6/(x - 1).

But, probability to pick two stale oranges is 2/21

7/x . 6/(x - 1) = 2/21

On solving,

x ² - x - 441 = 0

x = 21

Critical value used to test the claim that the mean number of restaurant employees is less than 15 at the 1% significance level is - 2.431

The square root of the variance is used to calculate the standard deviation, a statistic that gauges a dataset's dispersion from its mean. The variation from the mean of each data point is used to determine the standard deviation, which is equal to the square root of variance.

It is basically the average of the given numbers.

The given data is

Sample Size = n = 38

Sample mean = X = 12.6

Sample Standard deviation = S = 2.4

No the results did not deviate significantly from what would be expected due to chance.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean. The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

The average rate of change of the function f(x) from x = 1 to x = 2 is, -3.75 when the function f(x)=20(1/4)ˣ.

Given that,

We have to find what is the function f(x)=20(1/4)ˣ average rate of change from x = 1 to x = 2.

We know that,

Average rate of change(A(x)) of f(x) over a interval [a,b] is given by:

A(x)=(f(b)-f(a))/b-a

We get the function:

f(x)=20(1/4)ˣ

Now, the average rate of change from x = 1 to x= 2

At x = 1

Then;

f(1)=20(1/4)¹=5

At x = 2

Then;

f(2)=20(1/4)²=1.25

Substitute these in above formula we have;

A(x)=f(2)-f(1)/2-1=-3.75

Answer:

x = 0.6 , x = 2

Step-by-step explanation:

the absolute value function always gives a positive value, that is

| - a | = | a | = a

the expression inside the bars, however , can be positive or negative, so

9 - 8x = 2x +3 ( subtract 2x from both sides )

9 - 10x = 3 ( subtract 9 from both sides )

- 10x = - 6 ( divide both sides by - 10 )

x = 0.6

Or

- (9 - 8x) = 2x + 3

- 9 + 8x = 2x + 3 ( subtract 2x from both sides )

- 9 + 6x = 3 (add 9 to both sides )

6x = 12 ( divide both sides by 6 )

x = 2

As a check

substitute these values into the equation and if both sides are equal then they are the solutions.

x = 0.6

left side = | 9 - 8(0.6) | = | 9 - 4.8 | = | 4.2 | = 4.2

right side = 2(0.6) + 3 = 1.2 + 3 = 4.2= left side

-------------------------------------------------------

x = 2

left side = | 9 - 8(2) | = | 9 - 16 | = | - 7 | = 7

right side = 2(2) + 3 = 4 + 3 = 7 = left side

the solutions to the equation are x = 0.6 and x = 2

We insert m and c values inside the slope-intercept form to get a linear equation that expresses the volume of water in the bottle in terms of t:  w = 5t + 5.

Let w be the quantity of water in the bottle after turning on the faucet.

The following points can be drawn from the provided statement:

(t1, w1) = (4, 25)

(t2, w2) = (11, 60)

The equation of a line's slope-intercept form is:

w = mt + c

Put the values to find slope m.

m = (w2 - w1)/(t2 -t1)

m = 60 - 25 / 11 - 4

m = 5

Put m = 5, t = 4 and w = 2 in equation of the line;

w = mt + c

In this case, the standard error would be standard error = 2.50 / sqrt(41) = 0.342 and the z-score would be z = (5.61 - 5.00) / 0.342 = 1.71

A z-score value is the numerical measured value of the relationship of a value to the mean of a group of values and it is measured in the terms of standard deviations from mean value.

The z-score is measured by formula z=(x- μ)/ a where x is the raw score, μ is the population mean and a is the population standard deviation. So to calculate z-score, we subtract the population mean from the raw score and divide it by the population standard deviation.

standard error = population standard deviation / sqrt(sample size)

standard error = 2.50 / sqrt(41) = 0.342

Next, you would need to calculate the z-score for the observed mean wait time of 5.61 minutes.

In the given question;

Given: PR bisects ∠QPS. PQ=12 units, and PS=12 units.

Prove: QR≅SR

We have to find how we prove QR≅SR.

As we can see that;

PQ = PS

Since PR is bisector.

So PR is common in both triangles PRQ and PRS.

PR=PR

Since PR is bisector.

So ∠PRQ=∠PRS

As we know that if two sides and one angle are congruent, then using the Side-Angle-Side (SAS) Theorem, the both triangle is congruent.

So ∠PRQ≅∠PRS

So QR≅SR

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The statement made by Christopher is correct, this is because a fraction is always either greater or lesser than 1. And multiplying a fraction to a whole number will give result either greater or less than the whole number, depending upon the type of fraction it is.

For example let's take the number 100,

Let's take a proper fraction, 2/5. Therefore, the result will be,
