Answer: $135

Step-by-step explanation:

We have the ratio 1 : 3.

Kim gets $90 more than Jake.

So 1 : 3 can also be written as x : x+90

If x * 3 equals x+90, we can create the equation 3x=x+90. Solving this results in x being equal to 45

Kim gets $135 (x+90=45+90=135)

The dot product a . b is -22

The dot product, also known as scalar product or inner product, is a binary operation that takes two vectors and returns a scalar (single-valued) quantity. The dot product of two vectors is equal to the product of the magnitude (length) of the vectors and the cosine of the angle between them.

Given two vectors, A and B, the dot product is defined as:

A ∙ B = |A| * |B| * cos(θ)

where |A| and |B| are the magnitudes of vectors A and B, and θ is the angle between them.

a = <3, -2>

b = <-2, 8>

a . b = (3 * -2) + (-2 * 8)

a . b = -6 + - 16

a . b = -22

If the measure of <2 is 5 less than 4 times the measure of <1. The measure of angle <1 is 37 degrees, and the measure of angle <2 is   143 degrees. The measure of angle <3 is 55 degrees.

Let's call the measure of angle <1 "x".

From the problem, we know that:

4 times the measure of angle <1 is equal to the measure of angle <2 plus 5:

4x = measure of angle <2 + 5

So the measure of angle <2 is 4x - 5.

Next, we know that the measures of all angles in a triangle must add up to 180 degrees.

Therefore, we have:

x + (4x - 5) + measure of angle <3 = 180

Expanding and simplifying:

5x - 5 + measure of angle <3 = 180

5x + measure of angle <3 = 185

5x = 185

Finally, solving for x:

x = 37

So the measure of angle <1 is 37 degrees, and the measure of angle <2 is 4 * 37 - 5 = 143 degrees. The measure of angle <3 is 185 - 5x = 185 - 5 * 37 = 55 degrees.

Range, interquartile range, standard deviation, and variance are four measures of variability that can be used to compare two data sets.

area:

Difference between highest and lowest values.

Range is the straightforward allowance to calculate variability. To asset the area, follow these steps:

Sort all the values ​​in the dataset from lowest to highest.

Subtract the lowest value from the highest value. Interquartile range:

area of ​​the middle half of the distribution

standard deviation:

mean distance from mean

Standard deviation is a useful measure of the variance of a normal distribution.

A normal distribution distributes data symmetrically without skew. Most of the values ​​are clustered around the central region, with values ​​tapering away from the center. Standard deviation indicates how far the data are, on average, from the center of the distribution.

deviation:

A manufacturer working at the 430 gram setting, and a 21 bag sample had a mean of 421 grams with a standard deviation of 15. The p-value of test statistic is 0.0074.

To test whether the bag filling machine works correctly at the 430 gram setting, we can conduct a one-sample t-test. The null hypothesis is that the true mean weight of the bags filled by the machine is equal to 430 grams, and the alternative hypothesis is that the true mean weight is less than 430 grams.

The test statistic is calculated as:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

Plugging in the values given in the problem, we get:

t = (421 - 430) / (15 / sqrt(21)) = -2.77

The degrees of freedom for the t-distribution are n - 1 = 20.

Using a t-table or calculator, we can find the p-value associated with a t-score of -2.77 and 20 degrees of freedom. The p-value turns out to be 0.0074 (rounded to four decimal places).

Since the p-value is less than the level of significance of 0.1, we can reject the null hypothesis and conclude that the bag filling machine is underfilling the bags at the 430 gram setting.

The true statement about JK and JL is, JK is longer than JL

The process of comparison reveals the shared characteristics of several objects. This is the fundamental idea in mathematics that guides our descriptions of whether two numbers are equal, one is more than, one is less than, or both are equal. Comparing fractions, decimals, and rational numbers are all possible.

The coordinates of the point are:

J (2, 4)

K (7, 8)

L (1, -1)

The distance between two points is given by the formula:

D = √(x2 - x1)² + (y2 - y1)²

The distance between JK is:

JK = √(7 - 2)² + (8 - 4)

JK = √25 + 16 = √41 = 6.40

The distance between JL is:

JL = √(1 - 2)² + (-1 - 4)²

JL = √1 + 25 = √26 = 5.09

Hence, the statement about JK and JL is, JK is longer than JL.

The value of x by using the addition postulate of an acute angle is 36.

Acute angles are those between 0 and 90 degrees, and those angles are less than 90 degrees. When two rays intersect at a vertex, an angle is created.

An acute angle is one that is smaller than 90 degrees in length and has all internal angles that are less than 90 degrees.

Here, we have an acute angle NCQ that is 70 degrees. Using the addition postulate to determine the value of x, we have:

x + 34 = 70

x = 70 + (-34)

x = 70 - 34

x = 36

the probability of getting (a, b), i.e. the first card is a and the second card is b is 2/3 by conditional probability.

The potential of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability. It is computed by dividing the likelihood of the earlier occurrence by the likelihood of the subsequent, or conditional, event.

This is where the independent event and dependent event notion is used. Consider a student who misses class twice each week, omitting Sunday. What are the possibilities that he will take a leave of absence on Saturday of the same week if it is known that he will be absent from school on Tuesday? It has been noted that situations where the outcome of one event influences the outcome of a subsequent event are termed as conditional probability

We can work this out directly from the definition of conditional probability,

[tex]P(G_1|G_2)=P(G_1nG_2)/(P(G_1)[/tex]

Exactly one of the three cards has sides, so

P(G1∩G2)=1/3

There are 4,431,621,036,503,680 different ways to seat the 60 students in 62 seats.

If there are 60 students and 62 seats, then there will be 2 empty seats in the classroom. We need to find out the number of ways to seat the 60 students in these 62 seats.

To solve this problem, we can use the permutation formula:

nPr = n! / (n - r)!

where n is the total number of objects and r is the number of objects we want to arrange.

In this case, we want to arrange 60 students in 62 seats, so we can use the formula as follows:

62P60 = 62! / (62 - 60)!

= 62! / 2!

The probability of 3 students arriving at a randomly selected office hour is 0.27(27%). This can be calculated by using the Poisson distribution equation which is P(x)=e^(-λ)*(λ^x/x!).

In the above equation, λ is equal to the average number of arrivals which is 3.3. Plugging these values into the equation gives us  P(3)= e^(-3.3)*(3.3^3/3!) = 0.27, this means that the probability of 3 students arriving in randomly selected office hours is 0.27.The Poisson distribution is used to calculate the probability of a certain number of events occurring in a fixed interval of time or space. It is commonly used in engineering, economics, and other fields.

This equation is especially useful in situations like this one where the arrival rate is known and the probability of a certain number of arrivals needs to be determined.

well, the 25 mi/hr limit is expecting anyone on that road to only do 40,234 meters per hour, so since an hour is 60 minutes and a minute is 60 seconds, that means an hour is really (60)(60) seconds, or 3600 seconds, so the limit is expecting anyone on that road to do no more than 40,234 meters per 3600 seconds, let's see how Usain fares

[tex]\begin{array}{ccll} meters&seconds\\ \cline{1-2} 100 & 9.63\\ 40234& x \end{array} \implies \cfrac{100}{40234}~~=~~\cfrac{9.63}{x} \implies 100x=(40234)(9.63) \\\\\\ x=\cfrac{(40234)(9.63)}{100}\implies x\approx 3874.53[/tex]
