Answer: 0.31

Step-by-step explanation:

0.3158 is closer too 0.3100 than 0.3000 or 0.3

Rounding 0.3058 to the nearest hundredth gives us 0.31.

Given that a number we need to round it to the nearest hundredth,

To round 0.3058 to the nearest hundredth, we need to look at the digit in the thousandth place (the third decimal place).

Step 1: Look at the digit in the thousandth place. In this case, the digit is 5.

Step 2: Determine if the digit is 5 or greater. If the digit is 5 or greater, we round up. If the digit is less than 5, we round down.

Since the digit in the thousandth place is 5, we round up.

Step 3: Round up the number in the hundredth place. In this case, the number in the hundredth place is 0.

Rounding up 0 to the nearest hundredth gives us 1.

Therefore, rounding 0.3058 to the nearest hundredth gives us 0.31.

The value of "x" is the unknown number that, when multiplied by 12, gives a result of 72. By solving the equation, we find that the unknown number is 6.

Let's call the unknown number "x". The statement "When 12 is multiplied by a number, the result is 72" can be represented mathematically as:

12 * x = 72

This equation states that when we multiply 12 by the unknown number "x", we obtain a product of 72. To find the value of "x", we need to solve this equation.

To solve for "x", we can divide both sides of the equation by 12:

(12 * x) / 12 = 72 / 12

Simplifying, we have:

x = 6

Therefore, the equation that fits the given statement is:

12 * x = 72

Where "x" is equal to 6.

In this equation, the value of "x" is the unknown number that, when multiplied by 12, gives a result of 72. By solving the equation, we find that the unknown number is 6.

The probability that she succeeds at 10 or more free throws in a sample of 12 free throws is 4/5.

What is probability?

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

Here, we have

The probability that Shruti succeeds at any given free throw is 80%. She was curious how many free throws she can expect to succeed in a sample of 12 Free-throws. She simulated 25 samples of 12 free throws where each free throw had a 0.8 probability of being a success.

The probability that she succeds at 10 or more free-throws in a sample of 12 free-throws is estimated from  the simulation with 25 samples of 12 free-throws:

=  number of times she succeded at 10 or more free-thrown /number of trials

The number of times she succeeded at 10 or more free throws is equal to the sum of the number of times she succeeded at 10 + the number of times she succeeded at 11 + the number of times she succeeded and 12 free throws.

9 + 9 + 2 = 20

The number of trials is 25.

Probability (10 or more successes) = 20/25 = 4/5

Hence, the probability that she succeeds at 10 or more free throws in a sample of 12 free throws is 4/5.

The probability of A1 occurring given B1 is approximately 0.375, rounded to three decimal places.

To find the probability of P(A1|B1), we can use Bayes' theorem:

P(A1|B1) = (P(B1|A1) * P(A1)) / P(B1)

Given that A1 and A2 are complements, P(A2) can be calculated as 1 - P(A1), which means P(A2) = 0.7.

We are given P(B1|A1) = 0.6 and P(B1|A2) = 0.5.

Now, to calculate P(B1), we can use the law of total probability:

P(B1) = P(B1|A1) * P(A1) + P(B1|A2) * P(A2)

Substituting the given values, we get:

P(B1) = (0.6 * 0.3) + (0.5 * 0.7)

= 0.18 + 0.35

= 0.53

Finally, we can calculate P(A1|B1) using Bayes' theorem:

P(A1|B1) = (P(B1|A1) * P(A1)) / P(B1)

= (0.6 * 0.3) / 0.53

≈ 0.375

Therefore, the probability of A1 occurring given B1 is approximately 0.375, rounded to three decimal places.

When moving from a 95% confidence interval to a 90% confidence interval, the width of the interval will decrease. (option b).

To understand this, let's consider a simple example. Suppose we want to estimate the mean height of all high school students in a particular region. We take a sample of 100 students and calculate the mean height to be 65 inches, with a 95% confidence interval of (63, 67) inches. This means that if we were to repeat this process many times, we would expect the true population mean height to be within this interval 95% of the time.

Now, if we were to calculate a 90% confidence interval instead, we would obtain a narrower interval because we are now willing to accept a greater risk of being wrong.

It is important to note that the width of the confidence interval depends on the sample size and the variability of the data.

As the sample size increases or the variability decreases, the confidence interval will become narrower. Conversely, as the sample size decreases or the variability increases, the confidence interval will become wider.

Hence the correct option is (b)

The final answers are (0, 0, 0), 4x²y³ - 9y²z² + 2y⁵, and 6x²y - 6xyz - 2xz² + 4x²z + 2yz² - 2z³ respectively.

a) curl [grad (f²)]
First, calculate grad (f²).

grad (f²) = (2xy-2yz, 2xy-2xz, 2yz-2xz)

Now, calculate the curl of grad (f²).

curl of grad (f²) = (0, 0, 0)

The final answer is (0, 0, 0).

b) [(curl v) x w].w
First, calculate curl v.

curl v = (0, -4x-2y, -2z)

Now,

calculate [(curl v) x w].[(curl v) x w] = (2y(2z) - (4x+2y)(y²), -(4x+2y)(3z² - y²) - 2z(2y), (4x+2y)(y²) - 3z²(2y))

= (-4xy² + 2yz² + 4x²y - 2y³, -12x²z - 6yz² - 4xy² - 2z³ + 2y³, 8x²y - 6yz² - 6y²z)

cw = (3z²y², -2x²y² + y⁴, y⁴)

Then, calculate [(curl v) x w].w.[(curl v) x w].w

= (-12x²z - 6yz² - 4xy² - 2z³ + 2y³)(3z²y²) + (8x²y - 6yz² - 6y²z)(y⁴) + (-4xy² + 2yz² + 4x²y - 2y³)(y⁴)

The final answer is 4x²y³ - 9y²z² + 2y⁵.

c) [(grad f) x v].v
First, calculate grad f.

grad f = (y, x-z, -y)

Now, calculate

[(grad f) x v].[(grad f) x v] = (2z²y - 4y²x - 2yz², 4x³ - 8x²z - 2z³ + 2xy², 4xy² - 8xyz + 2xz² + 4y²z)

= (-2z(2xy-yz), 2x(2x²-2xz+z²-2y²), 2y(2x²-2yz+y²))

= (-2z(xy-yz), 2x(x²-xz+z²-y²), 2y(x²-yz+y²))

= (2yz-zxy, xz-x²+xy²-y², -xy+y²-yz)cv

= (3z², 2x²-y², y²)

Then, calculate

[(grad f) x v].v.[(grad f) x v].v = (2yz-zxy)(2y) + (xz-x²+xy²-y²)(2z) + (-xy+y²-yz)(4x+z)

The final answer is 6x²y - 6xyz - 2xz² + 4x²z + 2yz² - 2z³.

After performing the required calculations, we get the final answers as (0, 0, 0), 4x²y³ - 9y²z² + 2y⁵, and 6x²y - 6xyz - 2xz² + 4x²z + 2yz² - 2z³ respectively.
