Answer:

k = -10

Step-by-step explanation:

1) Because of the division of the left side of the equation by 2, multiply both sides of the equation by 2, which means you now have :

-8 - 3k = 22

2) Now, add eight to both sides. Your equation now looks like this:

-8 + 8 - 3k = 22 + 8

3) Simplify.

-3k = 30

4) You now have k = -10

The F value (1.617) is greater than the critical value of F (1.547), we reject the null hypothesis that the population variances are equal.

To test whether the population variances are equal, we can use the F-test. The null hypothesis is that the population variances are equal, and the alternative hypothesis is that they are not equal.

The test statistic for the F-test is:

F = s₁² / s₂²

where s₁² is the sample variance of the first population and s₂² is the sample variance of the second population.

Under the null hypothesis that the population variances are equal, the F statistic follows an F distribution with (n1-1) degrees of freedom in the numerator and (n2-1) degrees of freedom in the denominator, where n1 and n2 are the sample sizes of the two samples.

In this case, n1 = n2 = 40, so we have (40-1) = 39 degrees of freedom in the numerator and (40-1) = 39 degrees of freedom in the denominator.

Substituting the given values, we get:

F = (8² / 6.5²) = 1.514

The critical value of F at a significance level of 5% with 39 degrees of freedom in the numerator and 39 degrees of freedom in the denominator is 1.514.

We can conclude that there is sufficient evidence to suggest that the population variances are not equal.

Answer:

x=4

Step-by-step explanation:

72 + 51 + 13x + 5 = 180

128 + 13x = 180

13x = 52

x = 4

Answer:

x = 4

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

72 + 51 + 13x + 5 = 180 add like terms

128 + 13x = 180 subtract 128 from both sides

13x = 52 divide both sides by 13

x = 4

Answer:

130 degrees

Step-by-step explanation:

Since angles P and Q are supplementary (meaning that they add up to 180), we can set up the equation:

180 = 50 + Q

Q = 130

Answer: B) 180°

Step-by-step explanation:

Angle P and Q forms a straight line which means they add up to 180 degrees.

So angle P is 50 degrees then we need to find it's supplement.

Using the equation 50 + x = 180 we can solve for x to find the supplement.

50 + x = 180   subtract 50 from both sides

-50        -50

x = 130

Answer:

Please check the explanation.

Step-by-step explanation:

Let suppose we have a point P(x, y) if we rotate our point 90 degrees counterclockwise about the origin, the new coordinates of the image of the point P can be obtained by switching 'x' and 'y' and making 'y' negative.

In other words,

P(x, y) → P'(-y, x)

From the given triangle ΔRST,

The coordinates of the point S is:

According to the rule, if we have a point S(10, 1), after rotations of 90 degrees counterclockwise about the origin, the new coordinates of the image of the point S(10, 1) will be:

S(10, 1) → S'(-1, 10)

Here,

S'(-1, 10)  is the image of the original point or pre-image point S(10, 1).

Therefore, the y-coordinate of the point S' is: 10

For a sample of 72 batteries, the probability that the average battery life of the sample exceeds 1173.8 minutes is 0.9918.

It states a battery life variance of 8100 minutes and a median battery life of 1192 minutes.

In a sample of 72 batteries, find the probability that the average battery life (x) of the sample exceeds 1173.8 minutes.

Due to the large sample size (n = 72), we can use the central limit theorem to assume that the sample mean follows a normal distribution with mean μ = 1192 and standard deviation σ = sqrt(8100/72) = 30.

So the z-score for x= 1173.8 is

z = (x - μ) / (σ / sqrt(n))

= (1173.8 - 1192) / (30 / square(72))

= -2.4

You can use a standard normal distribution table or calculator to find the probability that a  standard normal random variable is greater than -2.4. This is 0.9918 (rounded to four decimal places).

Therefore, for a sample of 72 batteries, the probability that the average battery life of the sample exceeds 1173.8 minutes is 0.9918 (rounded to four decimal places) if the claim is correct.

The length of MN is roughly 13.89 units.

The polygonal shape of a triangle has three sides and three corners. It is one of the fundamental geometric shapes. Triangle ABC is a symbol for a triangle with vertices A, B, and C. When three points are not collinear, unique triangles and planes are found using Euclidean geometry.

Triangle JKL and triangle MNO are comparable, thus we can use the aspect ratio to determine the appropriate side lengths.

MN is 'x' in length. Then, it appears as follows:

JK/MN = 26/x, and KL/NO = 19/x

We can use their ratio to get x because we are aware of the lengths of JK and KL. We obtain: using the first ratio.

26/x = 58/26

x=26*26/58

x = 26^2/58

Compute the length of the curve r(t)=3ti+2tj+(t2−4)k over the interval 0≤t≤8 HINT use the formula ∫t2+a2​dt=21​tt2+a2​+21​a2ln(t+t2+a2​)+C

To compute the length of the curve given by the vector function r(t) = 3ti + 2tj + (t²2 - 4)k over the interval 0 ≤ t ≤ 8, we can use the arc length formula:

L = ∫√(dx/dt)²2 + (dy/dt)²2 + (dz/dt)²2 dt

First, let's find the derivatives of x, y, and z with respect to t:

dx/dt = 3

dy/dt = 2

dz/dt = 2t

Now, we can substitute these derivatives into the arc length formula:

L = ∫√(3²2 + 2²2 + (2t)²2) dt

L = ∫√(9 + 4 + 4t²2) dt

L = ∫√(13 + 4t²2) dt

To integrate this expression, we can use the hint given:

∫√(13 + 4t²2) dt = 1/2 ∫(1 + 4t²2)²(1/2) dt

                  = 1/2 [t√(1 + 4t²2) + (1/4)ln(t + √(1 + 4t²2)) + C]

Now we can evaluate this expression over the interval 0 ≤ t ≤ 8:

L = 1/2 [(8√(1 + 4(8²2)) + (1/4)ln(8 + √(1 + 4(8²2)))) - (0√(1 + 4(0²2)) + (1/4)ln(0 + √(1 + 4(0²2))))]

One would least expect to find fossils in the surface bedrock in the Adirondack Mountains region of New York State.

This region is known for having some of the oldest rocks in North America, dating back over a billion years. These rocks were formed through volcanic activity and mountain-building processes that occurred long before the evolution of complex life forms.

As a result, the rocks in the Adirondack Mountains are generally not rich in fossils, especially those of plants and animals that evolved much later in Earth's history.

In contrast, other regions of New York State, such as the Hudson Valley and the Finger Lakes region, have rocks that are more conducive to fossil preservation. These regions were covered by shallow seas at various times in the past, allowing for the accumulation of sediment and the preservation of fossils of marine organisms.

The displacement of the particle over the given time interval is -310 meters and the distance traveled by the particle over the given time interval is 310 meters.

First, let's clarify the given information:

v(t) = 8 - 20t (velocity function in meters/second)
Time interval: [1, 6]

Now, let's address each part of the question:

a) Find the displacement of the particle over the given time interval:

To find the displacement, we need to integrate the velocity function v(t) to get the position function s(t) and then evaluate the difference in position at the endpoints of the time interval.

1. Integrate v(t): ∫(8 - 20t) dt = 8t - 10t^2 + C (position function s(t))

2. To find the displacement, evaluate s(t) at the endpoints of the interval and find the difference:

Displacement = s(6) - s(1)
= (8(6) - 10(6)^2) - (8(1) - 10(1)^2)
= (48 - 360) - (8 - 10)
= (-312) - (-2)
= -310 meters

b) Find the distance traveled by the particle over the given time interval:

To find the distance traveled, we need to find the absolute value of the integral of the velocity function over the given interval.

1. Since we already have the position function s(t), we can find the distance by evaluating the absolute value of the difference in position:

Distance = |s(6) - s(1)|
= |-310|
= 310 meters

The arc length of the partial circle is L = 18.849 units

The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. It is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle.

The central angle of a circle formula is as follows.

Central Angle = ( s x 360° ) / 2πr

where s is the length of the arc

r is the radius of the circle

Central Angle = 2 x Angle in other segment

Given data ,

Let the radius of the circle be r = 4 units

Let the arc length of the circle be L

Let the central angle be = 270°

So , Central Angle = ( s x 360° ) / 2πr

On simplifying , we get

L = ( 270° / 360° ) x 2πr

L = ( 3/4 ) ( 8π )

In a horse race with four horses where ties are possible, there are a total of 15 different ways for the horses to finish, considering all possible combinations of two-way, three-way, and four-way ties.

Let's consider the different cases given by the number of ties:

No ties: In this case, all four horses finish in a unique order. The number of ways for this to happen is 4! (4 factorial) which is equal to 24.

Two-way ties: Two horses finish in a tie, while the other two horses finish separately. There are three possible ways to select the two horses that tie, which can be represented as (2, 2) in terms of the number of horses in each group. Once the two horses that tie are chosen, there are 2! (2 factorial) ways for the other two horses to finish among themselves. Therefore, there are 3 * 2! = 6 ways for this case.

Three-way tie: Three horses finish in a tie, while the remaining horse finishes separately. There are four possible ways to select the horse that finishes separately. Once that horse is chosen, there is only one way for the three tied horses to finish among themselves. Therefore, there are 4 * 1 = 4 ways for this case.

Four-way tie: All four horses finish in a tie. In this case, there is only one way for them to finish.

Adding up the possibilities from all the cases, we have 24 + 6 + 4 + 1 = 35. However, since we're accounting for ties, we need to subtract the case where there are no ties (24) to avoid counting it twice. Therefore, the final number of ways for the horses to finish is 35 - 24 = 11.

A relation a on N/(a,b) e Rif and only if EN the properties that R satisfy is a. Reflexive

Checking whether R is reflexive requires seeing if (n, n) exists for every natural integer n. R is defined as "a is related to b if and only if an is an element of N," which implies that every natural number is connected to itself. R is reflexive as a result. As per definition of R, "a is related to b if and only if an is an element of N." As a result, if a and b are connected, an is an element of N. However, this does not necessarily indicate that b is a component of N. R is not symmetric.

Since a is related to b if and only if it is an element of N, applying to R, this indicates that the presence of (a, b) in R implies that an is an element of N. Nevertheless, this says nothing about whether or not (b, a) is in R. R is not symmetric or antisymmetric as a result. Since the statement "a is related to b if and only if an is an element of N," applies to R, then the presence of (a, b) in R indicates that an is an element of N. R's transitivity cannot be ascertained because this does not reveal whether or not relation (b, c) is in R.
