The value of the angle x is 30 degrees
How to determine the valueTo determine the value of the variable x, we need to know the triangle sum theorem.
The triangle sum theorem is a theorem in mathematics stating that the sum total of the interior angles in a triangle is equivalent to 180 degrees.
We should also note that angle at right angle is 90 degrees
Then, we have the angles written as;
90 degrees
2x degrees
x degrees
Equate the angles , we have;
2x + x + 90 = 180
collect the like terms, we have;
2x + x = 180 - 90
add or subtract the like terms, we have;
3x = 90
divide by the coefficient
x = 30

Analyze the situation. Identify a reasonable domain and range for the situation.The revenue earned from a sporting event can be determined by the ticket price, $125 each.
In this situation, we have revenue from a sporting event. We have the ticket price is $125.
In this case, we have that the function is:
\(f(x)=125\cdot x\)We can see, that the domain are the possible assistants to this sporting event, and x could be any possible value equal to or greater than 0 or (assistants are 0 (nobody) or more):
\(x\ge0\)The revenue is the possible values for the function, and they could be also those for values equal to or greater than 0 (the earnings are zero (nothing) or more), or:

Perform the test at the significant level is 0.05. A field biologist examined the sex ratio at birth of the lesser snow geese. A random sample of nests containing four eggs was taken. For each egg resulting in a live gosling, the laying order and the gender of the gosling were recorded. Of the 27 successfully hatched first eggs, 17 were male. Is there significant evidence that the proportion of male goslings is not 50%.
Using an hypothesis test, it is found that:
The p-value of the test is 0.177 > 0.05, which means that there is not significant evidence that the proportion of male goslings is not 50%.
----------------------------
Test if the proportion of male goslings is different of 50%.At the null hypothesis, it is tested if the proportion is of 50%, that is: \(H_0: p = 0.5\)At the alternative hypothesis, if is tested if the proportion is different of 50%, that is: \(H_1: p \neq 0.5\)----------------------------
The test statistic is given by:
\(z = \frac{X - p}{\sqrt{\frac{p(1-p)}{n}}}\)
In which
p is the proportion tested.X is the sample proportion.n is the size of the sample.----------------------------
The proportion tested is 0.5, thus \(p = 0.5\)The sample proportion is 17 out of 27, thus \(n = 27, X = \frac{17}{27} = 0.6296\).----------------------------
The value of the test statistic is:
\(z = \frac{X - p}{\sqrt{\frac{p(1-p)}{n}}}\)
\(z = \frac{0.6296 - 0.5}{\sqrt{\frac{0.5\times0.5}{27}}}\)
\(z = 1.35\)
----------------------------
Two-tailed test, thus the p-value of the test is P(|z| > 1.35), which is 2 multiplied by the p-value of z = -1.35.Looking at the z-table, z = -1.35 has a p-value of 0.0885.The p-value of the test is: \(0.0885 \times 2 = 0.177\)The p-value of the test is 0.177 > 0.05, which means that there is not significant evidence that the proportion of male goslings is not 50%.

NZ is the angle bisector of ∠LNM. What is LZ? Enter the numerical value only.
Answer:
LZ = 3
Step-by-step explanation:
given NZ is the angle bisector of ∠ LNM , then it divides the opposite side into segments that are proportional to the other 2 sides, that is
\(\frac{LZ}{MZ}\) = \(\frac{NL}{NM}\) ( substitute values )
\(\frac{LZ}{5-LZ}\) = \(\frac{3}{2}\) ( cross- multiply )
2 LZ = 3(5 - LZ) ← distribute parenthesis
2 LZ = 15 - 3 LZ ( add 3 LZ to both sides )
5 LZ = 15 ( divide both sides by 5 )
LZ = 3
(y+3)=−34(x−4) find the point and the slope
Answer:
Slope: -34
Point: (4, -3)
Step-by-step explanation:
This equation is written in point-slope form. The equation of a line in point-slope form is written as (y - y_1) = m(x - x_1).
x_1 and y_1 are the x and y coordinates of one point.m is the slope of the line.We are asked to find the point and slope of (y + 3) = -34(x - 4). We can automatically determine that the slope is -34 because that's where the variable, m, is. Next, we know that the x-coordinate is 4 because it's in the place of x_1. Lastly, the y-coordinate is -3 because it changes the subtraction sign to an addition sign, and it's in the place of y_1. Thus, the point would be (4, -3).

The physician’s order reads to administer Lasix 80 mg PO STAT. You have Lasix 20 mg tablets on hand. How many tablets will you administer to the patient ?
The nurse should administer 4 Lasix 20 mg tablets to the patient to achieve the prescribed dose of 80 mg.
To determine the number of Lasix 20 mg tablets that should be administered to the patient, we need to calculate how many tablets are equivalent to the prescribed dose of 80 mg.
Given that each Lasix tablet contains 20 mg of the medication, we can divide the prescribed dose (80 mg) by the dosage strength of each tablet (20 mg) to find the number of tablets needed.
Number of tablets = Prescribed dose / Dosage strength per tablet
Number of tablets = 80 mg / 20 mg
Number of tablets = 4 tablets
Therefore, the nurse should administer 4 Lasix 20 mg tablets to the patient to achieve the prescribed dose of 80 mg.
It is important to note that this calculation assumes that the Lasix tablets can be divided or split if necessary. However, it is crucial to follow the specific instructions provided by the prescribing physician or consult with a pharmacist if there are any concerns about the appropriate administration of the medication.
Additionally, it is important to consider any additional instructions, such as the frequency and timing of administration, as specified by the physician's order.

For the linear function built from the scatter plot, it is found that:
The slope of the line is of: 5.The intercept of the line is of: b = 500.The equation is of: y = 5x + 500.What is a linear function?The slope-intercept representation of a linear function is the rule presented as follows:
y = mx + b
The coefficients of the function and their meaning are listed as follows:
m is the slope of the function, representing the change in the numeric value of the output variable y when the input variable x increases by one.b is the y-intercept of the function, which is the numeric value of the output variable y when the input variable x has a value of 0.From the graph, we have that when x = 0, y = 500, hence the intercept of the line is:
b = 500.
When the input increases by 200, the output increases by 1000, hence the slope is:
m = 1000/2 = 5.
Thus the equation is:

Kendra surveyed 100 people who own a dog or a cat, or both. Of those surveyed, 15 one both a dog and a cat, and the number of people who people who own a dog is four times the number of people who own a cat. How many people surveyed own a cat?
Answer:
40people
Step-by-step explanation:
Let the number of those that owned a dog be x
Let the number of those that owned a cat be y
If the number of people who own a dog is four times the number of people who own a cat, then:
x = 4y
Since x+y =100
4y+y = 100
5y = 200
y = 200/5
y = 40
x = 4(40)
x = 160
Hence 40 people surveyed own a cat
The concerns about the impact of technology on our lives are growing. There have been
recent research reports about the negative impact of digital technology usage on stress,
work productivity, happiness, and overall well-being. In light of these concerns, a polling
organization asked technology experts about their opinion on our digital life and found
that 29% of the experts believe that in the future our lives will be more harmed than
helped by their digital environment. In an effort to confirm these results, a local tech
company decides to ask 215 randomly selected customers their opinions about their
digital life. Answer parts a through c below.
A
a. What is the probability that 35 or more people from this sample are concerned about
the digital environment?
The probability is
(Round to four decimal places as needed.)
The probability that 35 or more people from the sample of 215 customers are concerned about the digital environment is 0.7043.
To calculate the probability that 35 or more people from the sample of 215 customers are concerned about the digital environment, we can use the binomial distribution formula.
The binomial distribution is applicable here because we have a fixed sample size (215 customers) and each customer can be categorized as either concerned or not concerned.
Let's denote p as the probability that a randomly selected customer is concerned about the digital environment.
From the given information, we know that 29% of technology experts believe our lives will be more harmed than helped, so p = 0.29.
The formula for the probability mass function of the binomial distribution is:
\(P(X = k) = C(n, k) \times p^k \times (1 - p)^{(n - k)\)
Where:
P(X = k) is the probability of k successes (in this case, customers concerned about the digital environment)
C(n, k) is the number of combinations of n items taken k at a time
\(p^k\) is the probability of k successes
\((1 - p)^{(n - k)\) is the probability of (n - k) failures
Now, let's calculate the probability of having 35 or more customers concerned:
P(X ≥ 35) = P(X = 35) + P(X = 36) + ... + P(X = 215)
Using this formula, we can calculate the probability using a cumulative approach:
P(X ≥ 35) = 1 - P(X ≤ 34)
Calculating this probability requires summing up a large number of individual probabilities, which can be time-consuming.
Therefore, it is more practical to use statistical software or calculators to obtain an accurate answer.

a baby goraffe is about 6 1/2 feet tall at birth and grows about 1/2 foot per month for its first year. The function h=1/2m+61/2 represents the total height h of a baby giraffe for any number of months m within ita firat year. How much taller is the giraffe at the end of the month 11 than at the end of month 2
Answer: 4 and 1/2 ft (or 4.5 ft) taller.
Step-by-step explanation:
The function h(m) = (1/2)*m + (6 + 1/2) represents the height (on feet) of the giraffe as a function of the number of months, m.
We want to find the difference in the height between month 11 and month 2, then we need to find:
difference = h(11) - h(2)
We can directly calculate this:
difference = [ (1/2)*11 + (6 + 1/2)] - [(1/2)*2 + (6 + 1/2)]
difference = (1/2)*11 - (1/2)*2 = (1/2)*(11 - 2) = (1/2)*(9) = 9/2
And we can write 9 = 9 + 1, then:
difference = 9/2 = (8 + 1)/2 = 8/2 + 1/2 = 4 + 1/2
And this is in feet, then the girrafe is (4 and 1/2) ft taller on month 11 than on month 2.
