Answer:

2167.7 sq yds

Step-by-step explanation:

SA(cone) = πr² + πrs     ('s' = slant height)

= π(15)² + π(15)(31)

= 225π + 465π

= 690π

= 2167.7

Answer:

p = 39       f = 44    

Step-by-step explanation:

p = $ 1.73

f = $ 1.44

equation

p + f = 83

1.73 p + 1.44 (83 - p) = $ 130.83

p = 39 (amount of times fruit pies were sold).

Therefore,

p = 39

f = 44

His total expense each month is \(50 + 2.5\times g\). He wants to spend no more than 200, so it has to be less than that:

\(50 +2.5g < 200 \rightarrow 2.5g < 150 \rightarrow g <60\)

Since the training set consists of 40 observations, you would need to fill in the counts for each category based on the actual classifications made by the model using the 0.5 cutoff value.

To construct the confusion matrix for a 40-observation training set, we need to use a cutoff value of 0.5 to classify each profile observation as either interested or not interested. The confusion matrix is a tool that shows the performance of a classification model.

Let's denote the four possible outcomes as follows:
- True Positive (TP): The model correctly classified an observation as interested.
- True Negative (TN): The model correctly classified an observation as not interested.
- False Positive (FP): The model incorrectly classified an observation as interested when it was actually not interested.
- False Negative (FN): The model incorrectly classified an observation as not interested when it was actually interested.

Since we have a cutoff value of 0.5, any observation with a prediction score above or equal to 0.5 will be classified as interested, while any observation with a prediction score below 0.5 will be classified as not interested.

Based on this information, we can construct the confusion matrix:

                   Predicted Interested   Predicted Not Interested
Actually Interested       TP                           FN
Actually Not Interested    FP                           TN

Note that the values TP, TN, FP, and FN are counts of observations falling into each category.

In your case, since the training set consists of 40 observations, you would need to fill in the counts for each category based on the actual classifications made by the model using the 0.5 cutoff value.

Step-by-step explanation:

I took the math exam

Step-by-step explanation:

Let x be the amount invested at 6% so that 18000-x is the amount invested at 7.5% both in dollars.

The total interest in 3 years is $3330 so we can write: 0.06x(3)+0.075(18000-x)(3)=3330

Solve for x:

0.06x(3)+0.075(18000−x)(3)=3330

Step 1: Simplify both sides of the equation.

0.06x(3)+0.075(18000−x)(3)=3330

0.06x(3)+−0.225x+4050=3330(Distribute)

0.18x+−0.225x+4050=3330

(0.18x+−0.225x)+(4050)=3330(Combine Like Terms)

−0.045x+4050=3330

−0.045x+4050=3330

Step 2: Subtract 4050 from both sides.

−0.045x+4050−4050=3330−4050

−0.045x=−720

Step 3: Divide both sides by -0.045.

−0.045x/−0.045=−720/−0.045

x=16000

x=16000

So, the amounts borrowed are:

Step-by-step explanation:

It is important to note that the p-value does not directly represent the probability of making a mistake in the test. The p-value depends on the chosen significance level and the specific context of the hypothesis test.

There seems to be an incomplete sentence in your question. However, based on the information you provided, I can explain the concept of the p-value in hypothesis testing.

In hypothesis testing, the p-value is the probability of observing a test statistic as extreme as, or more extreme than, the one calculated from the sample data, assuming that the null hypothesis is true. It is a measure of the strength of evidence against the null hypothesis.

A p-value of 0.32 means that if the null hypothesis is true, there is a 0.32 probability of obtaining a test statistic as extreme as, or more extreme than, the one observed in the sample data.

Typically, in hypothesis testing, a significance level (α) is chosen before conducting the test. If the p-value is less than or equal to the significance level, usually 0.05, then the null hypothesis is rejected in favor of the alternative hypothesis. If the p-value is greater than the significance level, the null hypothesis is not rejected.

It is important to note that the p-value does not directly represent the probability of making a mistake in the test. The interpretation of the p-value depends on the chosen significance level and the specific context of the hypothesis test.

The values that satisfy the inequality are -3 , 0 , 14 .

A connection that compares two numbers or other mathematical expressions inequitably is known as an inequality in mathematics. On the number line, size comparisons between two numbers are typically conducted. Different notations can be used to represent various kinds of inequalities, including:

The symbol a <b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

A is not equivalent to b in any scenario. Since an is strictly less than or strictly greater than b, these relationships are known as stringent inequalities. Equivalence is not considered.

Now the given inequality is of the form  -a < 4

solving we get:

a > - 4

Therefore the number which will satisfy this inequality are:

 -3 , 0 , 14 .

Answer:

X≈ 70.5°

Step-by-step explanation:

Using the cosine rule in Δ XYZ

cos X = \(\frac{y^2+z^2-x^2}{2yz}\)

with x = 22, y = 20, z = 18 , then

cos X = \(\frac{202+18^2-22^2}{2(20)(18)}\)

          = \(\frac{400+324-484}{720}\)

          = \(\frac{240}{720}\) , then

∠ X = \(cos^{-1}\) (\(\frac{240}{720}\) ) ≈ 70.5° ( to the nearest tenth )
