Answer:

7.5×10^-3

Step-by-step explanation:

\( \frac{ 0.027}{64000} = \frac{2.7 \times{10}^{ - 2} }{6.4 \times {10}^{4} } \)

due to the law of indices :

\( = 4.21875 \times 10 ^{ - 7} \)

don't forget

(0.027/64000)⅓

so :

\( ({4.21875 \times {10}^{ - 7} })^{ \frac{1}{3} } \)

i.e third root of the answer above

\( = 7.5 \times {10}^{ - 3} \)

The commutative property is valuable because it cuts the number of multiplication/addition facts to be learned in half.

The commutative property states that numbers can be added or multiplied in any order, without affecting the outcome. It only applies to addition and multiplication. This property makes it possible to minimize the number of multiplication or addition facts that need to be learned, making it a valuable tool.

It is vital to know the commutative property when adding or multiplying numbers because it provides a helpful shortcut to avoid unnecessary calculation. Additionally, the property can be applied to factorization to ease the computation process.The commutative property is one of the most fundamental properties of addition and multiplication. It aids in the simplification of arithmetic computations and minimizes the amount of memorization required to master the basic math facts.

Answer:

Options (A) and (C)

Step-by-step explanation:

A). The given inequality is,

    x + y ≤ 2

    Solution area of the inequality is the shaded area below the line.

    Since (0, 0) lies in the shaded region, ordered pair will be a solution of this inequality.

B). For the inequality y ≤ \(\frac{3}{2}x-1\)

   Since, (0, 0) doesn't lie in the shaded region of this inequality, ordered pair will not be a solution of the inequality.

C). y > \(-\frac{1}{3}x-2\)

    In this graph (0, 0) lies in the shaded region of the inequality therefore, it will be a solution of the given inequality.

Therefore, Options (A) and (C) are the correct options.

The E-M algorithm is used to estimate the parameters mu and Sigma. The implementation in R involves defining the likelihood function, initializing the estimates, and using the E-M steps to update the estimates.

The E-M algorithm for estimating the mean and covariance matrix of a multivariate normal distribution from a set of observations can be performed in the following steps

Initialization: Choose initial values for the mean vector and covariance matrix.

Expectation step: Calculate the posterior probabilities of each observation belonging to each component of the mixture model using Bayes' theorem and the current parameter estimates.

Maximization step: Use the posterior probabilities to update the estimates of the mean vector and covariance matrix for each component of the mixture model.

Repeat steps 2 and 3 until convergence (i.e., until the change in the parameter estimates falls below a specified tolerance level).

In this case, we have a single multivariate normal distribution with unknown mean vector and covariance matrix. Therefore, we can perform the E-M algorithm to estimate these parameters directly.

Here is the R code for implementing the E-M algorithm

Step-by-step explanation:

You only need to flip your sign when dividing by a negative. 3x > 12 = x > 12/3 = x > 4. If the equation were -3x > 12, then it would be x < 4.

The harmonic mean would give equal weight to both of these trails, despite their different distances.

The harmonic mean would make the most sense when calculating the average one-way mileages for trails to different lakes. When it comes to calculating the average of one-way mileages for trails to different lakes, it's important to choose the appropriate type of average based on the nature of the data.

In this case, since we're dealing with mileages, one-way distances, and travel times, the best option would be the harmonic mean. The harmonic mean is defined as the reciprocal of the arithmetic mean of the reciprocals of a set of numbers. In other words, it's a weighted average of the reciprocals of the numbers.

This type of average is useful in situations where rates, speeds, or frequencies are involved.  In this case, the harmonic mean would be the most appropriate choice for calculating the average one-way mileage for trails to different lakes because it takes into account the fact that distances and travel times are inversely related.

For example, if one trail has a distance of 10 miles and a speed of 2 miles per hour, it will take 5 hours to travel that distance. On the other hand, if another trail has a distance of 20 miles and a speed of 4 miles per hour, it will also take 5 hours to travel that distance.

Therefore, the harmonic mean would give equal weight to both of these trails, despite their different distances.

Answer:

your correct answer is y=-1/5-3

Step-by-step explanation:

The linear equation of the line is y = -1/5x - 3 and y + 3 = -1/5(x - 0)

The slope is given as:

m = -1/5

The y-intercept is given as:

c = -3

A linear equation in slope intercept form is represented as:

y = mx + c

So, we have:

y = -1/5x - 3

The equation in point slope form is calculated as follows:

y = -1/5x - 3

Add 3 to both sides

y + 3 = -1/5x

Express -1/5x as -1/5(x)

y + 3 = -1/5(x)

Subtract 0 from x

y + 3 = -1/5(x - 0)

Hence, the linear equation of the line is y = -1/5x - 3 and y + 3 = -1/5(x - 0)

Step-by-step explanation:

First combine like terms on the right side (5x-10x) to get -5x +4

6-3x=-5x+4

then move the -5x over to get 2x because you would add the -5x to the -3x.

The initial quantity of Plutonium is 50 grams. The quantity present after 10 years is approximately 28.7 grams.

Given data, Half-life of Plutonium 241 is 14 years.

The quantity of Plutonium after t years is given by,

Q = 50(1/2)^(t/14)

a. To determine the initial quantity (t=0),

Put t = 0 in the given equation

Q = 50(1/2)^(t/14)

Q = 50(1/2)^(0/14) = 50(1)^0 = 50

Therefore, the initial quantity of Plutonium is 50 grams.

b. To determine the quantity present after 10 years,

Put t = 10 years in the given equation

Q = 50(1/2)^(t/14)

Q = 50(1/2)^(10/14) = 50(1/2)^(5/7)

Q = 50(0.57435) ≈ 28.7

Therefore, the quantity present after 10 years is approximately 28.7 grams.

Therefore the probability that  she buys at least one of the previous items is 0.1333

The area of mathematics known as probability deals with numerical descriptions of the likelihood that an event will occur or that a statement is true .A number between 0 and 1 is the likelihood of an event, where, broadly speaking, 0 signifies the event's impossibility and 1 denotes its certainty.

Given:

event A: she buys  red dress.

event B: she buys a blue dress.

event C: she buys a necklace.

the probability she will buy a red dress is 0.2,

the probability she will buy a blue dress is 0.4

there is 10% chance  she will buy a necklace =0.10

The probability she wants to buy at most one dress,

P(A or B or C) =0.2 +0.4 +0.1 -(0.08 -0.04 -0.02 +0.08)

P(A or B or C) =0.568

the probability she buys at least one of the previous items is

\(\frac{P(A or B or C)}{P(AorB andC)}\) = \(\frac{0.2 * 0.1 * 0.4}{(0.2 * 0.1)+(0.1 *0.4)}\)

 \(\frac{P(A or B or C)}{P(AorB andC)}\)= 2/15 =0.133

Answer:

Step-by-step explanation:

Geoff is feeling peckish, so he decides to pop into the shop and grab some snacks. He picks up a packet of crisps for 25p, a can of soup for 68p and a watermelon for £1.47. He wonders why the watermelon is so cheap, but he doesn't question it. He goes to the cashier and hands over a £5 note. The customer behind Geoff wonders "how much change does he get back?"

To figure this out, we need to add up the price of the snacks and take it away from the money Geoff gave. We can use a dot to show the pence as parts of a pound. For example, 25p = 0.25 pounds.

The price of the snacks is:

0.25 + 0.68 + 1.47 = 2.40 pounds

The money Geoff gave is:

5.00 pounds

The change is:

5.00 - 2.40 = 2.60 pounds
