The approximate net pay of Juanita is $500. Therefore, option B is the correct answer.
Given that, Juanita has a part-time job that pays $12/hour and works about 50 hours every month.
What is the net pay?Net pay means take-home pay or the amount employees earn after all payroll deductions are subtracted from their gross pay.
Now, total money earned in a month
= 12 × 50 = 600
Now
6.2% of 600 = $37.2
= 600 - 37.2 = $562.8
1.45% of 562.8 = $8.1606
= 562.8 - 8.1606 = $554.6394
10% of 554.6394 = $55.46394
= 554.6394 - 55.46394 = $499.17546
Total deductions = $499.17546
So, net pay = grass pay - deductions
= 600 - 105.9
= $499.17546
The approximate net pay of Juanita is $500. Therefore, option B is the correct answer.

Nutrition: A cat food manufacturer uses fish and beef by-products. The fish contains 12 g of protein and 3 g of fat per ounce. The beef contains 6 g of protein and 9 g of fat per ounce. Each can of cat food must contain at least 60 g of protein and 45 g of fat. Find a system of inequalities that describes the possible number of ounces of fish and beef that can be used in each can to satisfy these minimum requirements. Graph the solution set. Find its vertices.
A cat food manufacturer uses fish and beef by-products.
Let the number of ounces of fish = x
Let the number of ounces of beef = y
The fish contains 12 g of protein and 3 g of fat per ounce.
fish = 12x + 3y
The beef contains 6 g of protein and 9 g of fat per ounce.
Each can of cat food must contain at least 60 g of protein and 45 g of fat.

dr. guidry has decided to examine one of her relationships with a scatterplot to double-check for a curvilinear relationship. which relationship will be most important for her to examine?
Linear regressions can help to examine a curvilinear relationship.
It is possible for two variables to have a relationship known as a curvilinear relationship, in which one variable rises along with the other, but only until a certain point, beyond which the other variable falls as the rise of the first continues.
To evaluate the relationship between two numerical variables visually, scatterplots are utilized. Usually, the X axis represents the explanatory variable and the Y axis represents the dependent variable.
By generating a line that best fits your data, regression takes correlation a step further. While a straightforward linear regression analysis still gives us the R2 value, it now gives us a number that indicates the strength (slope) of the association between X and Y. This knowledge improves our comprehension of the underlying relationship and can be applied to forecast Y values given a certain value of X. However, instead of testing the null hypothesis that the slope of the line depicting the relationship between X and Y is zero, T-tests are now employed.
Hence linear regressions can help to examine a curvilinear relationship.

The alternative hypothesis(h1) says that the treatment causes a change in the scores.
What is a hypothesis test?
In statistics, hypothesis testing involves putting an analyst's presumption about a population parameter to the test. The data type used and the study's purpose will determine the methodology the analyst uses.
Using sample data, hypothesis testing determines whether a claim is plausible. These data could originate from a broader population or a process that creates data.

Which of the following is used to identify outliers in a set of data?
1.5(IQR)
1.5(range)
2(mean)
2(median)
The Interquartile range i.e 1.5 (IQR) is used to identify outliers in a set of data which is the correct answer would be option (A).
What is the Interquartile range (IQR)?We may build up a "fence" outside of Q1 and Q3 by using the Interquartile range (IQR) method of spotting outliers. Outliers are values that fall outside of this range.
To construct this barrier, we take 1.5 times the IQR, deduct it from Q1, and add it to Q3. This provides us with the lowest and maximum fence posts against which we will compare each observation.
Outliers are observations that are greater than 1.5 IQR below or above Q1. Minitab's default strategy for identifying outliers is this.
Therefore, the Interquartile range (IQR) is used to identify outliers in a set of data.
Hence, the correct answer would be option (A).

We have five pulse rates randomly selected with a mean of 74.4 beats per minute. We have four pulse rates given. We let x be the value of the fifth pulse rate. We have n equals 5 here since we have sample space of 5. We illustrate the mean of the pulse rates as

While describing a set of data, we always specify the focal point of any data set. The measure of central tendency is this. Every day, data are presented to us. We discover them in books, articles, bank statements, phone and utility bills, as well as in newspapers. There are so many; they are all around us. The challenge now is if we can identify some key characteristics of the data by focusing on only a few data points. The means, medians, and modes—measures of central tendency or averages—can be used to do this. When describing a set of data, a measure of central tendency locates the set's center.

[tex]\begin{gathered} 300\cdot x=h^2 \\ h=300\cdot\tan22\degree \\ h\approx121\text{ ft} \\ \therefore x=\frac{121^2}{300}\approx49\text{ ft} \end{gathered}[/tex]a binomial experiment with probability of success and trials is conducted. what is the probability that the experiment results in or more successes? do not round your intermediate computations, and round your answer to three decimal places. (if necessary, consult a list of formulas.)
The probability that the experiment results in 9 or more successes = 0.0676
A binomial distribution is given by,
P(X = x) = ⁿCₓ pˣ (1-p)ⁿ⁻ˣ ,
where p is the probability of success and x is the random variable for success in n trials.
A binomial experiment has only two outcomes- success or failure.
Here, the number of trials, n = 10
Probability of success = 0.63
The probability for 9 or more success = P( X = 9, 10)
= P (X = 9) + P(X = 10)
So P( X = 9) = ¹⁰C₉ (0.63)⁹ (1-0.63)¹⁰⁻⁹
= 10 x 0.0156 x 0.37
= 0.05772
and P(X = 10) = ¹⁰C₁₀ (0.63)¹⁰(1-0.63)¹⁰⁻¹⁰
= 1 x 0.009849 x 1
= 0.009849
Hence probability for 9 or more success = 0.05772 + 0.009849

The value of x for the given triangle is 30°.
According to the question,
We have the following information:
We have a triangle.
Three angles of the triangle are x°, 65° and (x+55)°.
We know that the sum of all the three angles of a triangle is 180°.
So, the sum of these angles will be 180°.
Now, adding three angles:
x° + 65° + (x+55)° = 180°
(2x+120)° = 180°
2x = 180-120
2x = 60
x = 60/2 (2 was in the multiplication on the left hand side. So, it is in the division on the left hand side.)
x = 30°

Heraldo starts a push-up challenge, and on the first day does 10 pushups, the second day he does 13, the third day he does 16, and so on.
Write the recursive definition for this sequence, and then find how many pushups he should do on the 20th day, if he continues.
Answer:
Day 20 = 67 pushups (64+3)
Step-by-step explanation:
Day 1 = 10 pushups Day 2 = 13 pushups (10+3) Day 3 = 16 pushups (13+3)
He does three more pushups each day.
So day 4 = 19 pushups (16+3)
Day 5 = 22 pushups (19+3)
Day 6 = 25 pushups (22+3)
Day 7 = 28 pushups (25+3)
Day 8 = 31 pushups (28+3)
Day 9 = 34 pushups (31+3)
Day 10 = 37 pushups (34+3)
Day 11 = 40 pushups (37+3)
Day 12 = 43 pushups (40+3)
Day 13 = 46 pushups (43+3)
Day 14 = 49 pushups (46+3)
Day 15 = 52 pushups (49+3)
Day 16 = 55 pushups (52+3)
Day 17 = 58 pushups (55+3)
Day 18 = 61 pushups (58+3)
Day 19 = 64 pushups (61+3)

We start by inputing 3 into the equation giving us -1 > -(3)/2
This means we have -1 > -3/2
Now we have to determine if this statement is true.
-1 Is greater than -3/2, because -3/2 is -1.5 as a decimal which is less than -1.
