In circle P, if mQR = 80 , and m QRT = 39 , find each measure

Statistics suggest that if a robbery remains unsolved for a specific period of time, it is highly unlikely to be solved according to available data.

Based on statistical analysis, there is a critical time frame within which the chances of solving a robbery are significantly higher. While the exact duration may vary depending on various factors such as the nature of the crime, available evidence, investigative resources, and the efficiency of law enforcement agencies, data suggests that the probability of solving a robbery declines as time progresses. This could be attributed to factors like fading memories of witnesses, loss of crucial evidence, or the diversion of investigative efforts to other cases. Consequently, prompt and diligent investigative work is crucial for increasing the likelihood of solving a robbery before it becomes increasingly difficult to resolve.

we have to calculate the total that the sum of the numbers on your dice is a number other than 11.

As we see in above data ,

Probability that the sum of number on dice is 11

= 1/18

P( Sum is other than 11 ) = 1 - P( sum is 11)

=> P( Sum is other than 11 ) = 1 - 1/18 = 17/18

Hence, the required probability is 17 /18.

The probability of a censorship attack succeeding in terms of α (the attacker's mining power) can be calculated using the state machine representing the possible chain forks.

The attacker's success probability relies on their ability to maintain a longer private chain and ultimately replace the honest chain. The success probability depends on the attacker's mining power (α), the honest network's mining power (1-α), and the current state of the chain forks.
In general, the probability of a fork succeeding from each active state in the state machine can be calculated using a recursive approach, taking into account the likelihood of the attacker mining a block and the honest network mining a block. By evaluating these probabilities for different values of α, one can estimate the likelihood of a successful censorship attack. Remember that higher α values increase the attacker's chances of success, while lower values make it more difficult to carry out such an attack.

The temperature on the 5th day is 2°C .

The critical t-value is approximately 1.753.

To find the critical value for a 96% confidence interval with a sample size of 15, we need to determine the t-value from the t-distribution table. The t-distribution table is a statistical tool used to determine the probability of a t-value given the degrees of freedom (df) and the desired level of significance (α).

In this case, we have a sample size of 15, which means our degrees of freedom are 14 (n - 1). Looking at a t-distribution table for 14 degrees of freedom and a 96% confidence interval.

This means that if we were to construct a confidence interval from a sample size of 15, the margin of error would be calculated by multiplying the critical t-value of 1.753 by the standard deviation of the sample and dividing by the square root of the sample size. The resulting interval would contain the population mean with 96% confidence.

It's essential to note that the critical value will change as the sample size and confidence level change. Therefore, it's crucial to use the correct table to find the corresponding critical values for a given dataset's sample size and confidence level.

Step-by-step explanation:

Answer: I asked my Alexa and she said that it was 0.625

65% of female humpback whales are shorter than 14.1565 meters.

Given that, a normal distribution with a mean of 13.7 meters and a standard deviation of 0.5 meters.

We know that, Z=(x-μ)/σ

Z=standard score, x=observed value, μ=mean of the sample and σ=standard deviation of the sample

The z-score for the 65th percentile is 0.8416

Here, where x = the 65th percentile, μ = the mean value, and σ = the standard deviation.

So, we can rearrange the formula as follows:

x = z × σ + μ

Substituting the values:

x = 0.8413 × 0.5 + 13.7

x = 14.1565 meters

Therefore, 65% of female humpback whales are shorter than 14.1565 meters.

The Laplace transform of sin(6t)sin(7t) is (1/2)[s / (s^2 + 1) - s / (s^2 + 169)].

To express sin(6t)sin(7t) as a difference of cosines, we can use the trigonometric identity:

sin(a)sin(b) = (1/2)[cos(a - b) - cos(a + b)]

In this case, a = 6t and b = 7t. Substituting these values into the identity, we have:

sin(6t)sin(7t) = (1/2)[cos(6t - 7t) - cos(6t + 7t)]

Simplifying further:

sin(6t)sin(7t) = (1/2)[cos(-t) - cos(13t)]

Now, let's find the Laplace transform of sin(6t)sin(7t) using the given tables of Laplace transforms and properties:

L{sin(6t)sin(7t)} = (1/2)[L{cos(-t)} - L{cos(13t)}]

Using the property of Laplace transforms for cosine functions, we have:

L{cos(at)} = s / (s^2 + a^2)

Applying this property to the above expression, we get:

L{sin(6t)sin(7t)} = (1/2)[s / (s^2 + 1) - s / (s^2 + 169)]

Simplifying further, we have:

L{sin(6t)sin(7t)} = (1/2)[s / (s^2 + 1) - s / (s^2 + 169)]

This is the Laplace transform of sin(6t)sin(7t) expressed as a difference of cosines.

Step-by-step explanation:

To determine the proportion of z-scores that fall outside the interval from z = -2.65 to z = 2.65, we need to calculate the area under the standard normal curve outside this interval. This can be done by subtracting the area under the curve between -2.65 and 2.65 from 1. The resulting value represents the proportion of z-scores that are outside the given interval.

The standard normal distribution has a mean of 0 and a standard deviation of 1. The interval from z = -2.65 to z = 2.65 represents a range of 2.65 standard deviations to the left and right of the mean.

To calculate the proportion of z-scores outside this interval, we need to find the area under the standard normal curve between -2.65 and 2.65. This area represents the proportion of z-scores within the interval.

We can use a standard normal distribution table or statistical software to find the area under the curve between -2.65 and 2.65. Once we have this value, we subtract it from 1 to obtain the proportion of z-scores that fall outside the interval.

Therefore, the proportion of z-scores outside the interval from z = -2.65 to z = 2.65 is 1 minus the area under the standard normal curve between -2.65 and 2.65.

To find the number of square feet that 1 pound of wildflower seeds will cover, we can set up a proportion using the given information.

Let's assume that "x" represents the number of square feet that 1 pound of wildflower seeds will cover. We can set up the proportion as follows:

212 pounds / 425 square feet = 1 pound / x square feet

To solve for "x," we can cross-multiply and solve the resulting equation:

212 * x = 1 * 425

212x = 425

Dividing both sides of the equation by 212:

x = 425 / 212

Simplifying the division:

x = 2

Therefore, 1 pound of wildflower seeds will cover an area of 2 square feet based on the given information and the calculated proportion.

Given, parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope intercept form

equation of line q is y = ₋10/9x ₊ 2

it's already in slope intercept form.

hence slope is:

m = (₋10/9) from the above the equation.

we know that the second line will also have a slope of ₋10/9 and we are given the point (9 , ₋3). We can setup an equation in slope intercept form and use these values to solve for the y inetrcept.

y = mx ₊ b

₋3 = ₋10/9 (9) ₊ b

₋3 = ₋10 ₊ b

b = 7

plug the y intercept back into the equation to get our final answer.

y = ₋(10/9)x ₊ 7
