a and b must be on opposite sides of zero​ (option D)

Explanation:

if a × b = c

and c is less than zero.

c can be less than zero if a < 0 and b > 0

c can be less than zero if b < 0 and a > 0

From the above, we can say a nd b must be on opposite sides this is because the left hand side of 0 shows > 0. While the right side of 0 shows > 0.

Hence, for a × b = c where c < 0,

a and b must be on opposite sides of zero​ (option D)

Answer:

(0,6) and (3,1)

Step-by-step explanation:

The equation is already in slope intercept form.

y = mx + b

Since the y-intercept is '6', the first point would be (0, 6).

-----------------------------------

We can move three units to the right and 5 units down to get our second point, (3,1).

Note that slope is rise over run.

(0 + 3, 6 - 5) - > (3, 1).

The points would be (0,6) and (3,1). After plotting, you would draw a continuous line through them.

The type of sampling being used when 5% of the registered voters from each county in a state are drawn at random separately is a stratified sampling.

Stratified sampling is the type of probability sampling that is used when the population being sampled has different groups or strata with varying characteristics. A sample is then drawn from each group to make sure that each stratum or group is represented.The samples can be of equal sizes or can be proportionate to the size of the group. The idea behind stratified sampling is to increase the representativeness of the sample by reducing the variability of the data obtained from the sample.

The advantages of using stratified sampling are that it reduces the variability of the data obtained and ensures that every group or stratum is represented. It also makes it possible to identify any differences between the groups and analyze them independently of the others.In summary, when 5% of the registered voters from each county in a state are drawn at random separately, it is an example of a stratified sampling.

Work Shown:

Plug in f(x) = 37. Solve for x. Use logarithms.

f(x) = 20(1.05)^x

37 = 20(1.05)^x

20(1.05)^x = 37

1.05^x = 37/20

1.05^x = 1.85

log( 1.05^x ) = log( 1.85 )

x*log( 1.05 ) = log( 1.85 )

x = log( 1.85 )/log( 1.05 )

x = 12.6088044498867

Therefore, there are 176,851,200 combination to award the prizes if there are no restrictions.

If there are no restrictions on how the prizes are awarded, we can use the formula for combinations with repetition to calculate the number of ways to award the prizes. Specifically, we want to choose 4 winners from 100 participants, where order does not matter and each winner can win multiple prizes.

The formula for combinations with repetition is:

(n + r - 1) choose r = (n + r - 1) / (r! * (n - 1)!)

where n is the number of objects to choose from (100 in this case), and r is the number of objects to choose (4 in this case).

Using this formula, we can calculate the number of ways to award the prizes as:

(100 + 4 - 1) choose 4 = (103 choose 4)

= (103 * 102 * 101 * 100) / (4 * 3 * 2 * 1)

= 176,851,200

Answer:

36√3 unit square

A=72*√3/2=36√3 unit square

The area of triangle PQR is 36√3 square units.

The area can be defined as the space occupied by a flat shape or the surface of an object.

Area = (1/2) × base × height

According to the given question.

We have a triangle PQR.

In which PQ = QR and PQR = 120.

Draw a perpendicular bisector PM on RQ such that RM = QM = 6.

Now in triangle PQM we have

\(sin120 = \frac{PM}{PQ}\)

⇒\(sin120 = \frac{PM}{12}\)

⇒\(\frac{\sqrt{3} }{2} =\frac{PM}{12}\)

⇒ \(PM = 6\sqrt{3}\)

Now, the area of triangle PQR is given by

Area of PQR = 2 ×  area of triangle PQM

Area of PQR = 2 × \(\frac{1}{2} (6)(6\sqrt{3} )\)

Area of PQR = 36√3

Hence, the area of triangle PQR is 36√3 square units.

We do not have much information to go on such as the speed that Tai is biking or his/her weight.

Regardless we can use the data gathered by the University of Harvard which after a study came up with the following results.

Their results showed that if an individual bikes at a speed of 13 mph and are around 155 pounds they will burn calories at a rate of 10 calories per minute.

Therefore we can assume that Tai is burning roughly 10 calories per minute.

his rate increases if the person bikes at a faster speed or weighs more as they are exerting more energy.

Step-by-step explanation:

Given independent, identically distributed exponential random variables X and Y with parameter λ, and their sum Z = X + Y, we can compute the conditional probability density function (pdf) and the conditional expected value of X. For part a, we calculate the conditional pdf of X given Z = z. For part b, we compute the conditional pdf of X given Z > t, where t is a given value.

a. To compute the conditional pdf of X given Z = z, we use the formula for conditional probability: \(P(X = x | Z = z) = \frac{f(x, z)} {g(z)}\), where f(x, z) is the joint pdf of X and Z, and g(z) is the marginal pdf of Z. Since X and Y are independent, their joint pdf is the product of their individual pdfs: \(f(x, z) = f(x) * f(z - x)\).

The marginal pdf of Z is obtained by convolving the pdfs of X and Y:

g(z) = ∫[0, z] f(x) * f(z - x) dx. Therefore, the conditional pdf of X given Z = z is \(P(X = x | Z = z) = f(x) *\frac{f(z - x)}{g(z)}.\).

b. To compute the conditional pdf of X given Z > t, we use a similar approach. We first calculate the conditional probability: \(P(X = x | Z > t) = \frac{f(x, Z > t)}{h(t)}\), where f(x, Z > t) is the joint pdf of X and Z conditioned on Z > t, and h(t) is the marginal probability that Z > t. The joint pdf can be expressed as: \(f(x, Z > t) = f(x) * P(Z > t - x)\).

The marginal probability h(t) is obtained by integrating the joint pdf over the appropriate range: h(t) = ∫[0, ∞] f(x, Z > t) dx. Finally, the conditional pdf of X given Z > t is \(P(X = x | Z = z) = f(x) *\frac{f(z - x)}{g(z)}.\)

By computing the conditional pdfs and integrating over the appropriate ranges, we can also determine the conditional expected value of X given the specified conditions.
