False. Comparing marginal distributions of two variables only gives information about each variable separately and not their relationship.

Comparing the marginal distributions of two variables only shows the distribution of each variable individually and not their relationship. For example, suppose we have two variables X and Y. If we compare the marginal distributions of X and Y separately, we may see that one variable has a higher frequency of a certain value than the other variable, but this does not necessarily imply that there is a relationship between the two variables. To determine whether there is a relationship, we need to look at the joint distribution of X and Y, which can be displayed in a scatterplot or analyzed using a correlation coefficient.

Answer: √3 is irrational whereas √9 is rational

Step-by-step explanation:

3x3=9. 3^2=9. but, ?x?=3 and ?^2=3. there is no number for that

The product of \(\sqrt{3}\) and \(\sqrt{9}\) is irrational

•

An irrational number is a type of real number which cannot be represented as a simple fraction and \(\sqrt{3}\) falls under this category. As fractions are just ratios, being multiplied by another number will not affect the ratio, thus making the product irrational.

Average is the best prediction. For the given case, if someone is wanting to  work for Fast Pax, then his salary is most likely to be around $39,500

Arithmetic mean is the best central measure available for representing the values of a data set.  It is also called average of the values of the considered data set.

It serves as one representation of the values of the data set. If for a data set, only its average is given, then we can't say much about the values of the data set, but we can  say that the data values are going to be around that average (average is closest number to its data set's values compared to any other number)

It serves as predicted value(in case no other information of the data is available) of that data set.

Average provides ill information in case of skewed data.

Thus, for the given case, as average annual salary for the Fast Pax is $39,800, so we can say that, the salaries of someone who wants to work for Fast Pax would be around $39,800 most probably.

Step-by-step explanation:

The measures of angle B is derived as 75° to the nearest degree using the cosine rules.

The cosines rule relates the lengths of the sides of a triangle to the cosine of one of its angles.

Using the cosine rule:

2² = 5² + (√45)² - 2(5)(√45)cosB

4 = 25 + 45 - 250cosB

4 = 70 - 250cosB

250cosB = 70 - 4 {collect like terms}

250cosB = 66

B = cos⁻¹(66/250) {cross multiplication}

B = 74. 6925°

Therefore, the measures of angle B is derived as 75° to the nearest degree using the cosine rules.

Answer:

The answer is C

Step-by-step explanation:

a) We need to evaluate whether the series generated by the absolute values converges in order to ascertain whether the series (n2 + 8)/(3 + 3n2) absolutely converges or diverges from n = 1 to infinity.

Take the series |n2 + 8|/(3 + 3n2) into consideration. Taking the absolute value has no impact on the series because the terms in the numerator and denominator are always positive. Therefore, for the sake of simplicity, we can disregard the absolute value signs.Let's simplify the series now: (1 + 8/n2)/(1 + n2) = (n2 + 8)/(3 + 3n2).

The words in the series become 1/1 as n gets closer to b, and the series can be abbreviated as 1/1.

The discounted price is $16, so the correct option is C.

if the percentage of the discount (in decimal form) is X, and the initial price is P, then the new price will be:

P' = P*(1 - X)

Here we know that the original price is $20, and the discount is of 20% (or 0.2 written as a decimal form).

Replacing that in the formula above we will get:

P' = $20*(1 - 0.2) = $16

∡ABC = ∡BCD (given)

AB = CD (given)

BC = BC (common)  } = > (SAS) ΔABC ≡ ΔBCD = > AC = BD

Side angle side congruency proves AC = BD as BC is common.

In geometry two objects or shapes are congruent if they have same shape and size we can also prove congruency by sides,angles.

According to the question ABCD is a quadrilateral given that AB = CB and ∠ABC = ∠ BCD.

Now if we draw two line segments AC and BD this will form two triangles

ΔABC and ΔADC in them BC is a common side And AB = CD also ∠ABC = ∠ BCD so by side angle side(SAS) congruency we can say that AC = BD.

The probability of getting all tails when flipping a coin three times can be calculated using the multiplication rule of probability. For each flip of the coin, there are two possible outcomes: heads or tails.

Assuming the coin is fair, both outcomes are equally likely, so the probability of getting tails on any one flip is 1/2.

P(all tails) = P(tails on first flip) x P(tails on second flip) x P(tails on third flip)

= (1/2) x (1/2) x (1/2)

= 1/8

Therefore, the probability of getting all tails when flipping a coin three times is 1/8 or 0.125 when expressed as a decimal rounded to four decimal places.

Sathish will pay $64.8

When Satish is alone, kilometres:

Beginning at 150 kilometres and ending at 150 kilometres will be travelled 300 kilometres in total

When Satish is with friends, the total kilometres travelled is 2100 km:

And when Satish went alone he travelled 300 km

When Satish is with friends, total kilometres travelled: 2100-300 = 1800 km

Gas consumed in litres when Satish is alone: 100 kilometres use 6 litres of gas.

300 kilometres at 6 x 3 equals 18 litres.

So, when Satish is with friends, litres of gas are consumed: 100 kilometres use 6 litres of gas.

So, 6 × 18 for 1800 kilometres is equal to 108 litres.

Gas prices when Satish is on his own:

$1.2 per litre

18 x $1.2 = $21.6

Gas prices when Satish is travelling with friends

$1.2 per litre

108 x 1.2 = $129.6

(a) To find the values of z for which the matrix does not have an inverse, we can set up the determinant of the matrix and solve for z when the determinant is equal to zero.

The given matrix is:

|x3  x|

|9   1|

The determinant of a 2x2 matrix can be found using the formula ad - bc. Applying this formula to the given matrix, we have:

Det = (x3)(1) - (9)(x) = x3 - 9x

For the matrix to have an inverse, the determinant must be non-zero. Therefore, we solve the equation x3 - 9x = 0:

x(x2 - 9) = 0

This equation has two solutions: x = 0 and x2 - 9 = 0. Solving x2 - 9 = 0, we find x = ±3.

So, the values of x for which the matrix has no inverse are x = 0 and x = ±3.

(b) (i) To find the size of the acute angle between the vectors (3,0) and (5,5), we can use the dot product formula:

u · v = |u| |v| cos θ

where u and v are the given vectors, |u| and |v| are their magnitudes, and θ is the angle between them.

Calculating the dot product:

(3,0) · (5,5) = 3(5) + 0(5) = 15

The magnitudes of the vectors are:

|u| = sqrt(3^2 + 0^2) = 3

|v| = sqrt(5^2 + 5^2) = 5 sqrt(2)

Substituting these values into the dot product formula:

15 = 3(5 sqrt(2)) cos θ

Simplifying:

cos θ = 15 / (3(5 sqrt(2))) = 1 / (sqrt(2))

To find the acute angle θ, we take the inverse cosine of 1 / (sqrt(2)):

θ = arccos(1 / (sqrt(2)))

(ii) If the vector (-k, 3) is orthogonal to (5,5), it means their dot product is zero:

(-k, 3) · (5,5) = (-k)(5) + 3(5) = -5k + 15 = 0

Solving for k:

-5k = -15

k = 3

So, the value of k is 3.

(c) Let J be the linear transformation from R2 to R2 that reflects points in the horizontal axis and then scales them by a factor of 2. The matrix of J can be found by multiplying the reflection matrix and the scaling matrix.

The reflection matrix in the horizontal axis is:

|1  0|

|0 -1|

The scaling matrix by a factor of 2 is:

|2  0|

|0  2|

Multiplying these two matrices:

J = |1  0| * |2  0| = |2  0|

   |0 -1|   |0  2|   |0 -2|

So, the matrix of J is:

|2  0|

|0 -2|

Therefore, y = 2 and z = -2.

Answer:

\( \sf \: 12th \: term = 37\)

Step-by-step explanation:

Common difference (d) is,

→ d = a2 - a1

→ d = -3 - (-7)

→ d = -3 + 7

→ [ d = 4 ]

Now the 12th term will be,

→ a1 + (d × (n - 1))

→ -7 + (4 × (12 - 1))

→ -7 + (4 × 11)

→ -7 + 44

→ 37 => 12th term

Hence, the answer is 37.
