add 3x^2-5+1 +2x^2+9x-6

Answer:

m∠K= 40

HI= 3

Step-by-step explanation:

For the first triangle, this is an isosceles triangle. So, that means that the bottom angles are equal to each other. And remember that a triangle sums up to 180 degrees. So, the equation would be: 70+70+m∠K= 180.

Step 1- Add to simplify.

(70+70)+m∠K= 180

140+m∠K= 180

Step 2- Subtract 140 to both sides.

140+m∠K= 180

-140             -140

m∠K= 40

For the second triangle, this is an equilateral triangle. This means that all sides are the same and all angles are the same. As you can see, the signs(loops) on the angle measurements are the same, so the sides are the same as well.

That means line HI is 3.

The domain of the function is a semicircle with a radius of 5 and centered at the origin, where y is non-negative.

The domain of a function is the set of all possible input values for which the function is defined. In this case, the function is defined as:

\(f(x,y) = \sqrt{y} + \sqrt{[25 - x^2 - y^2} ]\)

To find the domain of this function, we need to determine the values of x and y that would result in the function producing a real-valued output.

For the square root of y to be real, y must be non-negative. That is, y ≥ 0.

For the square root of [\(25 - x^2 - y^2\)] to be real, we must have:

\(25 - x^2 - y^2 \geq 0\\x^2 + y^2 \leq 25\)

This is the equation of a circle with radius 5 centered at the origin. Therefore, the domain of the function is the set of all points (x, y) that lie inside or on this circle and have y ≥ 0.

In interval notation, we can write:

Domain: {(x, y) |\(x^2 + y^2 \leq 25, y \geq 0\)}

To sketch the domain, we can plot the circle with radius 5 centered at the origin and shade the region above the x-axis. This represents all the valid input values for the function. The boundary of the domain is the circle, and the domain includes all points inside the circle and on the circle itself, but not outside the circle.

To estimate the number of sandwiches the deli manager should anticipate selling when 178 customers visit the deli, we can analyze the given data and approximate it using a linear function.

By observing the table, we notice that the number of sandwiches sold varies with the number of customers. This indicates a relationship between the two variables.

To estimate the number of sandwiches, we can fit a line to the data points and use the linear function to make predictions. Using a statistical software or a spreadsheet, we can perform linear regression analysis to find the equation of the best-fit line. However, since we are limited to text-based interaction, I will provide a general approach.

Let's assume the number of customers is the independent variable (x) and the number of sandwiches is the dependent variable (y). Using the given data points, we can calculate the equation of the line.

After calculating the linear equation, we can substitute the value of 178 for the number of customers (x) into the equation to estimate the number of sandwiches (y).

Please provide the data points for the number of sandwiches sold corresponding to each number of customers so that I can perform the linear regression analysis and provide a more accurate estimate for you.

a) A ∪ B = {8,14,17,16,9,15}

b) A ∩ B = {14,17}

c) probability that one of the numbers chosen at random is A' = 0.7

Venn diagrams are commonly used in mathematics, statistics, and logic to illustrate relationships between sets of data. It consists of circles that overlap to show the similarities and differences between the sets like in the case of students data.

From the venn diagram we have that:

A = {8,14,17}

B = {14,17,16,9,15

A' = {13,10,11,12,16,9,15}

U = {13,10,11,12,8,14,17,16,9,15}

so;

A ∪ B = {8,14,17,16,9,15}

A ∩ B = {14,17}

A' = 7

U = 10

probability that one of the numbers chosen at random is A' = 7/10 or 0.7

EQUATION: X - 12 = 7X. SOLUTION: X = - 2.

Step-by-step explanation:

First, we do not know the number. When the number is unknown, it is a variable. I chose the variable, "X."

12 less than signals that we subtract 12. So that would be X - 12.

A product of 7 AND that number means we multiply 7 by X. That can be notated as 7X.

12 less than X is EQUAL to the product of 7 and X. So X - 12 = 7X.

To find the solution, we want to know the value of X. Move X to one side of the equation.

X - 12 = 7X

-X           -X

_________

-12     =   6X

Divide both sides by 6 to get X by itself.

The probability that among 4 randomly selected motorists, the officer will find at least one motorist driving more than 5 miles per hour over the speed limit is 0.8704, rounded to the nearest ten-thousandth.

To solve this problem, we can use the complement rule, which states that the probability of an event happening is equal to 1 minus the probability of the event not happening.

First, let's find the probability that none of the 4 randomly selected motorists will be driving more than 5 miles per hour over the speed limit.

Since the officer estimates that 40% of motorists will be driving more than 5 miles per hour over the speed limit, then the probability of a motorist not driving more than 5 miles per hour over the speed limit is 1 - 0.4 = 0.6.

The probability that none of the 4 motorists will be driving more than 5 miles per hour over the speed limit is therefore:

0.6 x 0.6 x 0.6 x 0.6 = 0.1296

Now we can use the complement rule to find the probability that at least one of the 4 motorists will be driving more than 5 miles per hour over the speed limit:

1 - 0.1296 = 0.8704

Fencing of any rectangular region is basically represent perimeter of that rectangular region.

For most economical fencing, length L = 21.05 feet and width W = 13.301  feet.

Area of rectangular region is 280 square feet.

And length is L and width is W.

Area of rectangular region = L × W=280 square feet

W=280 / L

Since, The fence along three sides is to be made of material that costs 6 dollars per foot, and the material for the fourth side costs 14 dollars per foot.

Therefore, Total cost, C = 6(2L + W) + 13W = 12 L + 19 W

Total cost, C = 12 L+ 5,320 / L

To find most economical cost, differentiate above function and equate to zero.

C' = 12 - 5,320 / L²

simplifying the above equation, we get

⇒ 12 - 5,320 / L² = 0

⇒ L² = 5,320 / 12

L = 21.05 feet

Therefore, L = 21.05 feet

Substituting value of L in area equation.

P = 108

L = 2W+12

108 = 2(2W+12) + 2W

108 = 4W + 24 + 2W

108 = 6W + 24

84 = 6W

W = 14

If the width is 14, then the length is twice that plus 12, or 38

38 + 38 + 14 + 14 = 108

Based on the information provided, the necessary conditions for using the Z-Test for Proportions of 2 Independent samples are not fully met. The correct statement is: No, the samples aren't random and could lead to biased results.

For the Z-Test for Proportions of 2 Independent samples, the following conditions should be met:

Random Samples: The samples should be randomly selected from the respective populations. In this case, it is mentioned that the counselor randomly samples both seniors and juniors, which satisfies this condition.

Independence: The samples should be independent of each other. Since the samples are independently selected, this condition is met.

Large Sample Sizes: For the Central Limit Theorem (CLT) to hold, the sample sizes should be large enough. While the sample sizes are mentioned (100 seniors and 100 juniors), the proportions mentioned (93% and 87%) suggest that the conditions for the CLT for proportions may not be fully met. Both groups should ideally have a sufficient number of successes and failures for the CLT to apply.

Therefore, the correct answer is that the group of juniors does not have enough successes to meet the CLT for proportions. The group of seniors does not have enough failures to meet the CLT for proportions.
