Answer:

B) x = √118 mi

Step-by-step explanation:

This is a right triangle, so we can the measure of x using the Pythagorean theorem, which is

a^2 + b^2 = c^2, where

Step 1:  Plug in x and √26 for a and b and 12 for c and simplify:

x^2 + (√26)^2 = 12^2

x^2 + 26 = 144

Step 2:  Subtract 26 from both sides to isolate x^2:

(x^2 + 26 = 144) - 26

x^2 = 118

Step 3:  Take the square root of both sides to isolate x:

√(x^2) = √118

x = √118 mi

Grid Square is another name for the coordinate plane. It can be inferred therefore that the equation [y=-1/5x-2] is to be graphed.

To graph the above equation, we need to find the (x, y) pairs that satisfy the equation, then draw a line for the points.

Note that we can find this by simply substituting random values into x to find the y pair.

For example,

Where y = -(1/5)x - 2

If x = 1, then

y = (-(1/5) * 1) -2

y = -2.2

Where x = 2 then,

y = -2.4

Where x = 3

y = -2.6

Where x = 4

y = -2.8

Where x = 5

y = -3

Thus, the (x,y) pairs are as follows:

(1, -2.2)

(2, -2.4)

(3, -2.6)

(4, -2.8)

(5, -3)

Plotted on a graph, we would get the result attached.

Using the Poisson distribution formula, the probability of detecting a single network virus on a given day is approximately 0.1494 or 14.94%.

For the probability of seeing one network virus on any given day, we can use the Poisson distribution formula:

P(X = x) = (e^-λ * λ^x) / x!

Where:

P(X = x) is the probability of detecting x network viruses in a day

e is the mathematical constant e (approximately equal to 2.71828)

λ is the mean number of network viruses detected in a day

x is the number of network viruses detected in a day

Given that the mean number of network viruses detected in a day is 3.0, we have:

λ = 3.0

Now, the probability of detecting one network virus in a day, we plug x = 1 into the formula:

P(X = 1) = (e^-3.0 * 3.0^1) / 1!

= (0.0498 * 3.0) / 1 ⇒ 0.1494

Therefore, the probability of detecting one network virus on any given day is approximately 0.1494 or 14.94%.

In this scenario, if a computer was bought for $2350 and is being depreciated over 5 years, the annual depreciation is $470, and its value 3 years later would be $1410.

The straight-line method of depreciation is a method of calculating the decline in value of an asset over time. Using this method, an asset's value is spread evenly over its useful life.

In this scenario, if the computer was bought for $2350 and is being depreciated over 5 years, the annual depreciation is ($2350 / 5) = $470.

Three years later, the computer's value would be $2350 - ($470 x 3) = $1410. This is because the value of the computer is decreasing by $470 per year, and after three years, the total amount of depreciation would be $470 x 3 = $1410.

It's important to note that the straight-line method of depreciation is a simple method and it does not reflect the real-world scenario in which assets may have a higher value of depreciation in the initial years and less in the later years. But it's easy to calculate and use.

In conclusion, if an asset is depreciated using the straight-line method, its value decreases evenly over its useful life. It's important for businesses to understand the various methods of depreciation and choose the one that best suits their needs.

Answer:

Multiply 5/2 to both sides

Step-by-step explanation:

Doing so 'cancels' out the coefficient of (z+1) on the left-hand side.

The mean of the distribution of sample means is 56.7, and the standard deviation of the distribution of sample means is approximately equal to 4.82.

To calculate the mean of the distribution of sample means, we use the fact that the mean of a sample is an unbiased estimate of the population mean, and therefore the mean of the distribution of sample means is equal to the population mean. Thus, the mean of the distribution of sample means is 56.7.

To calculate the standard deviation of the distribution of sample means, we use the formula for the standard error of the mean, which is the population standard deviation divided by the square root of the sample size. Thus, the standard deviation of the distribution of sample means is equal to 75.9 divided by the square root of 246, which is approximately equal to 4.83.

Therefore, the mean of the distribution of sample means is 56.7, and the standard deviation of the distribution of sample means is approximately 4.83

:According to the question:You are working with a population of crickets. Before the mating season you check to make sure that the population is in Hardy-Weinberg equilibrium, and you find that the population is in equilibrium.

During the mating season you observe that individuals in the population will only mate with others of the same genotype (for example Dd individuals will only mate with Dd individuals). There are only two alleles at this locus ( D is dominant, d is recessive), and you have determined the frequency of the D allele =0.6 in this population. Selection acts against homozygous dominant individuals and their survivorship per generation is 80%. After one generation the frequency of DD individuals will decrease in the population.

According to the Hardy-Weinberg equilibrium equation p² + 2pq + q² = 1, the frequency of D (p) and d (q) alleles are:p + q = 1Thus, the frequency of q is 0.4. Here are the calculations for the Hardy-Weinberg equilibrium:p² + 2pq + q² = 1(0.6)² + 2(0.6)(0.4) + (0.4)² = 1After simplifying, it becomes:0.36 + 0.48 + 0.16 = 1This means that the population is in Hardy-Weinberg equilibrium. This is confirmed as the frequencies of DD, Dd, and dd genotypes

The postfix expression of "7+5-3*2(6*7)/4" is "7 5 + 3 2 * 6 7 * 2 * - 4 /". Evaluating the postfix expression gives the result of the expression. The prefix expression for the given infix expression is "/ - + 7 5 * 3 * 2 ( * 6 7 ) 4".

To convert the infix expression "7+5-3*2(6*7)/4" into postfix expression, we follow the rules of operator precedence and associativity. The postfix expression is obtained by placing operators after their operands.

The postfix expression for the given infix expression is:

"7 5 + 3 2 * 6 7 * 2 * - 4 /"

To evaluate the postfix expression, we use a stack data structure. We scan the postfix expression from left to right and perform the corresponding operations.

Starting with an empty stack, we encounter the operands "7" and "5". We push them onto the stack. Then we encounter the operator "+", so we pop the last two operands from the stack (5 and 7), perform the addition operation (7 + 5 = 12), and push the result back onto the stack.

We continue this process for the remaining operators and operands in the postfix expression. Finally, after evaluating the entire expression, the result left on the stack is the final answer.

To convert the infix expression into prefix expression, we follow similar rules but scan the expression from right to left. The prefix expression is obtained by placing operators before their operands.

Step-by-step explanation:

Tonia would need to pay Tonya $42.23 to cover the cost of all the items.

Tonya's total purchase was $34.23 + $11.75 + $16.25 = $62.23. She paid $50 and received $7.77 in change, which means she paid a total of $50 - $7.77 = $42.23 for her purchases. Therefore, Tonia would need to pay Tonya $42.23 to cover the cost of all the items.

Tonya purchased a jacket for $34.23, a pillow for $11.75, and a baseball cap for $16.25. She paid $50, and received $7.77 in change from the cashier. To find out how much she borrowed from her friend, first calculate the total cost of the items and the amount she actually paid:

Total cost of items = $34.23 + $11.75 + $16.25 = $62.23
Amount Tonya paid = $50 - $7.77 = $42.46

Now, subtract the amount she paid from the total cost of the items:

Amount borrowed from friend = $62.23 - $42.46 = $19.77

So, Tonya borrowed $19.77 from her friend to pay for all the items.

Step-by-step explanation:

Answer:

A.) Henry

B.) Thomas

Step-by-step explanation:

Given the following :

Henry's elevation = 10feets relative to sea level

Thomas elevation = -12 1/2 that is (-25/2) feet relative to sea level

Person with greater elevation:

Elevation can be described as height, in this case, the sea level used as the reference point. Therefore, a positive distance denotes an elevation above the reference point (which is the sea level). Therefore, Henry has a greater elevation of 10 feet( a distance above 0).

B) Who is farther from sea level:

This can be calculated by comparing the absolute distance between the elevation of both Henry and Thomas relative to the reference point(sea level)

Take reference point as 0

Absolute distances relative to sea level:

Henry's distance | 10 - 0 | = 10

Thomas's distance | -(25/2)- 0 | = 12 1/2

The  p-value is approximately 0.027 (rounded off to two decimal places).

To determine whether there is strong evidence that more than 15% of college students in America have at least one sibling, we can use a hypothesis test with a significance level of 0.05.

Let p be the proportion of college students in America who have at least one sibling. The null hypothesis is that p ≤ 0.15, and the alternative hypothesis is that p > 0.15.

Under the null hypothesis, the number of students in a sample of 100 who have at least one sibling follows a binomial distribution with parameters n = 100 and p = 0.15. We can use this distribution to calculate the probability of observing 20 or more students with at least one sibling in a sample of 100 if the null hypothesis is true.

The p-value is the probability of observing a test statistic as extreme or more extreme than the observed value, assuming the null hypothesis is true. In this case, the test statistic is the number of students with at least one sibling in a sample of 100.

Using a binomial distribution calculator or software, we find that the probability of observing 20 or more students with at least one sibling in a sample of 100 if p = 0.15 is approximately 0.027.

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is strong evidence that more than 15% of college students in America have at least one sibling.

Therefore, the p-value is approximately 0.027 (rounded off to two decimal places).
