How many prime numbers are a multiple of 5?.

The equation given is linear, not proportional, and thus, there is no constant of proportionality.

Here we have the following linear equation:

y = 5*x - 1/3

The general linear equation is:

y = m*X + b

Where m is the slope and b is the y-intercept, so in this case we have:

slope = 5

y-intercept = -1/3

Partocularly, when the y-intercept is 0 we have a proportional relation:

y = m*x

And then m is called the "constant of proportionality"

In this case the y-intercept is not zero, thus, there is no constant of proportionality, just a slope.

The flux of the given function f = x³i + y³j + z³k is given by f',

f' = 3(x²i + y²j + z²k)

Given, f = x³i + y³j + z³k

we have to find the flux of the given function f = x³i + y³j + z³k

On partial differentiating the function, we get

f' = 3x²i + 3y²j + 3z²k

f' = 3(x²i + y²j + z²k)

So, the flux of the given function f = x³i + y³j + z³k is given by f',

f' = 3(x²i + y²j + z²k)

Hence, the flux of the given function f = x³i + y³j + z³k is given by f',

The probability that the 5th card was the third and last jack is 0.016%

Standard card deck only have 4 jack cards and 48 other cards is not a jack. So, to calculate the probability is simply by dividing the number of favorable outcomes by the possible outcomes.

It is very important to note, wherever the first and second jacks are located it will not affect the calculation for the third jack.

So, you can calculate with this formula,
P(5th card is third and last jack) = (48/52)×(47/51)×(4/50)×(3/49)×(2/48)×(46/47)×(45/46)×(44/45)

or this formula,

P(5th card is third and last jack) = (4/52)×(3/51)×(48/50)×(47/49)×(2/48)×(46/47)×(45/46)×(44/45)

After we simplified calculation, we get

= (4 × 3 × 2 × 44) ÷ (52 × 51 × 50 × 49)

= 0.00016 or 0.016%

Thus, the probability is 0.016% for the third and last jack on 5th card.

What is correlation?

In statistics, the correlation is a technique used to determine the relationship between the two variables. The correlation's range is from -1 to +1. There are three primary categories of correlation: no correlation, positive correlation, and negative correlation. When the correlation value is zero, there is no association; the correlation value that is closest to zero indicates the weakest degree of relationship.

We must select the set of correlations in the question that accurately displays the highest to the lowest degree of relation.

Option B is the best choice since we must take the absolute value into account in order to determine the relationship's degrees. Here, the absolute values drop from 0.91 to 0.03.

Option A is incorrect since the absolute values decline from 0.91 to 0.03 and then climb to 0.10 in this situation.

Because the absolute values are not listed in decreasing order, Option C is incorrect.

The speed of rocket when it is very far away from the the rocket is 9990 m/s.

In the given question, a rocket is launched straight up from the earth's surface at a speed of 15000 m/s.

v = 15000m/s = 1.5×10^{4} m/s

We have to find the speed of rocket when it is very far away from the the rocket.

As we know,

Mass of Earth(M) = 5.972×10^{24} kg

Radius of Earth(R) = 6.371×10^{6} m

The value of G = 6.67×10^{-11}

Applying law of conservation of energy,

-GMm/R + 1/2 mv^2 = 0+1/2 mV^2

Taking common m on both side, we get

-GM/R + v^2/2 = V^2/2

Substituting the value

-(6.67×10^{-11})(5.972×10^{24})/ 6.371×10^{6} + (1.5×10^{4})^2/2 = V^2/2

V^2/2 = -6.67×5.972×10^{-11+24}/ 6.371×10^{6} + 2.25×10^{8}/2

V^2/2 = -6.252×10^{13-6} + 1.125×10^{8}

V^2/2 = -6.252×10^{7} + 11.25×10^{7}

V^2/2 = 4.998×10^{7}

Multiply by 2 on both side we get

V^2 = 9.996×10^{7}

V^2 = 99.96×10^{6}

Taking square root on both side, we get

V = 9.99×10^{3}

V = 9990 m/s

Hence, the speed of rocket when it is very far away from the the rocket is 9990 m/s.

The correct option representing Tracy's total investment is a. $4,940.00.

She bought 150 shared of Upton group that offers each share at the price of $18.96. So, the cost of 150 shares = 150 × 18.96

Performing multiplication on Right and Side of the equation

The cost of 150 shares from Upton group = $2844

The cost of 100 shares of WHI health = 100 × 20.96

Performing multiplication on Right and Side of the equation

The cost of 100 shares of WHI Health = $2096

The total investment will be sum of the cost of these shares.
