|x| + |x-2| =

Let x= 1

|1| + |1-2| =

|1| + |-1| =

The absolute value means take the non negative value

1 + 1 = 2

If a sample includes three individuals with scores of 4, 6, and 8, the estimated population variance is (4 + 0 + 4) / 2 - 4. So, correct option is 4.

The estimated population variance formula is the sum of squared deviations from the mean divided by the degrees of freedom. In this case, the degrees of freedom would be n-1, where n is the sample size.

Using the given sample of 4, 6, and 8, we can calculate the sample mean as (4+6+8)/3 = 6.

Then, we calculate the deviations from the mean for each score:

4 - 6 = -2

6 - 6 = 0

8 - 6 = 2

We square each deviation to get 4, 0, and 4. Then, we sum the squared deviations: 4 + 0 + 4 = 8.

Since there are three scores in the sample, the degrees of freedom is 3 - 1 = 2.

Finally, we divide the sum of squared deviations by the degrees of freedom to get the estimated population variance: 8/2 = 4.

Therefore, option 4) (4 + 0 + 4) / 2 = 4 is the correct answer.

The coordinates of the midpoint are (-6, -34) and the distance between M and N is approximately 27.8.

find the coordinates of the midpoint of a segment with the given endpoints M(6,-41) and N(-18,-27), you can use the midpoint formula.

The midpoint formula is:
Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)

Using the given endpoints, the coordinates of the midpoint are:
Midpoint = ((6 + -18) / 2, (-41 + -27) / 2)
Midpoint = (-6, -34)

Now, to find the distance between the points M(6,-41) and N(-18,-27), you can use the distance formula.

The distance formula is:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Using the given coordinates, the distance between M and N is:
Distance = sqrt((-18 - 6)^2 + (-27 - -41)^2)
Distance = sqrt((-24)^2 + (14)^2)
Distance = sqrt(576 + 196)
Distance = sqrt(772)
Distance ≈ 27.8

So, the coordinates of the midpoint are (-6, -34) and the distance between M and N is approximately 27.8.

The probability that exactly 2 of them are left handed is equal to  approximately 0.98415 or 98.4%.

Percent of people left handed is equal to 10%

Number of people selected at random = 6

Use the binomial distribution to find the probability of exactly 2 people out of 6 being left-handed,

With a probability of success being left-handed is equal to 0.1.

The probability of exactly x successes in n independent trials,

Each with probability of success p, is given by the binomial probability mass function,

P(k) = (ⁿCₓ) × pˣ × (1-p)ⁿ⁻ˣ

where  (ⁿCₓ) is the binomial coefficient, which represents the number of ways to choose x items out of n.

Here we have,

n = 6  as 6 people are selected.

p = 0.1 the probability of a success being left-handed.

x= 2

find the probability of exactly 2 people being left-handed.

Plugging these values into the formula, we get,

⇒P(2) = ⁶C₂ × 0.1² × 0.9⁴

Evaluate this expression as,

The integral of sin(x) with respect to x is -cos(x) + C, where C is the constant of integration.

The integral ∫sin(x) dx, we can use the basic integration rule for the sine function. The antiderivative of sin(x) is -cos(x), so the integral evaluates to -cos(x) + C, where C is the constant of integration.

The constant of integration, denoted by C, is added to the antiderivative because the derivative of a constant is zero. It accounts for the infinite number of possible functions that differ by a constant value.

The sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle. The sine function is used to find the unknown angle or sides of a right triangle.

The statement says that you've triggered the Penalty APR so that it has now increased to 28.99%. What action triggered this? You failed to pay the minimum payment by the due date.

You failed to make the minimum payment by the due date. This is an action that can result in a message that "you've triggered the Penalty APR so that it has now climbed to 28.99%."

A charge APR is a charge that can be applied if you don't pay your bills on time. It may be set up so that future transactions may be subject to a penalty APR that is higher than the card's standard rate.

If the minimum payment was not made by the due date, Penalty APR would be applied.

But if the card also has a penalty APR and you trigger it, you will likely lose that promotional offer. Federal consumer protections that limit penalty APRs don't apply to small-business credit cards. That means issuers can be more punitive, such as applying penalty APRs sooner than 60 days after not making payments.

point slope form would be

( y - - 3) = 1/2 (x-2)       you can re-arrange as

y = 1/2x -4

To eliminate the roots in 1.1 and 1.2, we can use trigonometric substitution. In 1.1, we can substitute x = 4 sin(theta) to eliminate the root of 4. In 1.2, we can substitute z = 7 sin(theta) to eliminate the root of 7.

1.1. V64+2 + 1 We can substitute x = 4 sin(theta) to eliminate the root of 4. This gives us:

V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3 1.2. V4z2 – 49

We can substitute z = 7 sin(theta) to eliminate the root of 7. This gives us:

V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta) (2 – 1) = 7 sin(theta)

Here is a more detailed explanation of the substitution:

In 1.1, we know that the root of 4 is 2. We can substitute x = 4 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 2.

When we substitute x = 4 sin(theta), the expression becomes V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3

In 1.2, we know that the root of 7 is 7/4. We can substitute z = 7 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 7/4.

When we substitute z = 7 sin(theta), the expression becomes: V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta)

The actual distance between Beitbridge and Musina is 3,900,000 kilometers.

To calculate the actual distance between Beitbridge and Musina, given the scale of the map and the measured distance on the map, we can use the concept of scale.

The scale of the map is given as 1:3,000,000, which means that 1 cm on the map represents 3,000,000 cm in real life.

The measured distance on the map between Beitbridge and Musina is 1.3 cm.

To find the actual distance, we can set up a proportion using the scale:

1 cm on the map / 3,000,000 cm in real life = 1.3 cm on the map / x km in real life.

Simplifying the proportion, we have:

1 / 3,000,000 = 1.3 / x.

Cross-multiplying, we get:

x = (1.3 * 3,000,000) / 1.

x = 3,900,000 / 1.

x = 3,900,000 km.

Answer:

92%

Step-by-step explanation:

To get an average generally:

\(avg = \frac{a_1+a_2+a_3+...}{n}\)

where n is the amount of numbers you are averaging.

We are not given the sum of the scores of Joe's 6 tests, but we can find it by plugging into the formula.

\(78 = \frac{x}{6}\)

where x is the sum of his first 6 tests. Solving for x:

\(x = 78(6)\\x = 468\)

We can use this sum to substitute for the first 6 tests in order to find the score of the 7th test.

\(80 = \frac{468+y}{7}\)

where y is the score of the 7th test that will result in an average of 80. We now simply solve for y:

\(7(80) = 468 + y\\560-468 = y\\y = 92\)

So, Joe must receive a score of 92% on his 7th test in order to have an average of 80%.

L = lengh

W = width

french reasoning ( hello from France ) !

The base of the house is a rectangle where the length of a rectangle is 8 more than the width.

=> L = W + 8

and

Its area is 240 ft sq

W x L = 240

L = W + 8

W x L = 240

=> W x (W+8) = 240

W² + 8W - 240 = 0

Δ = 8² - 4*1*(-240) = 32²

W' = (-8 + 32) / 2 = 12 ft

W'' = (-8 - 32) / 2 = impossible

at the end

W the width = 12 ft

and then the lengh = 12 + 8 = 20

area = 12 x 20 = 240 ft²
