Answer:

Between markers 3 and 4.

Explanation:

We know that each student runs 2 / 11 miles. Given this, how many miles do the first two students run?

The answer is

Now, we know that the course has markers every 0.1 miles. How many markers are ther in 4 /11 miles?

The answer is

This is between markers 3 and 4. Meaning that the second student finishes between markers 3 and 4.

Answer:

300 in²

Step-by-step explanation:

Hello!

Because the diagonal forms right triangles, we can use the Pythagorean Theorem to find the missing length of the rectangle.

a² + b² = c²

In this case, 25 is c, and 15 is a. We can solve for b using the formula.

So the missing length of the rectangle is 20. We can find the area by multiplying 15 and 20

The area is 300 in².

Types of solutions in a system of equations:

Based on this image, we can see that when they are parallel lines (same slope), there is no solution because the lines never touch.

The type of solution Martin was describing is when the lines are the same (letter b in the image) and it looks like one line when graphed.

Answer: We disagree with Martin because the lines never touch, meaning that the system has no solutions.

Suppose that the parent function is expressed as

This implies that the parent function is transformed by a horizontal shift to the left by four spaces.

The correct option is

For 1, we have the following triangle:

Using the cosine function to get the hypotenuse we get:

Now that we have the hypotenuse, we can find the remaining side using the pythagorean theorem:

Therefore, the value of the remaining side is 7.

What is Kite?

A kite is a quadrilateral having reflection symmetry across a diagonal in Euclidean geometry. A kite has two equal angles and two pairs of adjacent equal-length sides as a result of its symmetry.

Given,

ABCD is a kite, with the diagonal AD and BC

We have,

               AC = AB

and

               CD = BD                [Property of Kite]

In ΔACD and ΔABD

                AC = AB

and

               CD = BD               [Property of Kite]        

               AD = AD               [Common]

By rule SSS Criteria [Side Side Side ]

              ΔACD ≅ ΔABD

 ∴           ∠CDA = ∠BDA         [CPCT]

Now,

         In ΔCDE and ΔBDA

                 CD = BD

            ∠CDE = ∠BDE

                 DE = DE                [Common]

By rule SAS Criteria [Side Angle Side]  

            ΔCDE ≅ ΔBDA

∴                CE = BE                [CPCT]  

Hence, AD bisects BC into equal parts

The missing reasons are

ΔCDA ≅ ΔBDA  by SSS [side side side]

ΔCED ≅ ΔBED by SAS [side angle side]

Since the function describing the height is a quadratic function with negative leading coefficient this means that this is a parabola that opens down. This also means that the maximum height will be given as the y component of the vertex of the parabola, then if we want to find the maximum height, we need to write the function in vertex form so let's do that:

Hence the function can be written as:

and its vertex is at (1.9,19.9) which means that the maximum height of the ball is 19.9 m

c = price of a slice of Cheese pizza

m= price of a slice of mushroom pizza

Jack bought 3 slices of cheese pizza and 4 slices of mushroom pizza fora total cost of $12.50

3c + 4 m = 12.50

Grace bought 3 slices of cheese pizza and 2 slices of mushroom pizza for a total cost of $8.50.

3c + 2m = 8.50

We have the system of equations:

3c + 4 m = 12.50 (a)

3c + 2m = 8.50 (b)

Subtract (b) to (a) to eliminate c

3c + 4m = 12.50

-

3c + 2m = 8.50

_____________

2m = 4

Solve for m:

m = 4/2

Round to 3 decimal placed the value of the irrational number e.

Step-by-step solution/explanation;

The letter e in mathematics is also known as the Eular's number and is a mathematical constant used in many calculations especially natural logarithms of numbers.

The value of the Eular's number is approximately;

It can continue till infinity, however approximations of this number is always used to avoid unnecessary complications.

Therefore, rounded to 3 decimal places, the value of e is now;

ANSWER:

Note that we take 3 digits aftre the decimal and then if the fourth digit after the decimal is 5 or greater than 5, we make it 1 and add that 1 to the third digit after the decimal. Otherwise we simply make it zero and cancel it along with all other digits after it.

The digit that follows 8 (third digit) is less than 5, therefore, we write it off along with all other digits after it, and we are left with the decimal point and then ...718.

Option C is the correct answer.

we need to find the value of h when D is 9, so we need to replace D by 9 and find h:

Answer:

Explanation:

Given the sequence with the recursive formula:

First, we determine the first three terms in the sequence.

Therefore, the first three terms of the sequence are: 7, 14 and 28.

This is a geometric sequence where:

• The first term, a=7

• The common ratio, r =14/7 = 2

We use the formula for the nth term of a GP.

The explicit formula for the sequence is:

Given:

The inside diameter of the pope, I.D.=0.599 in.

The outside diameter of the pope, O.D.=1.315 in.

The inside radius of the pope is,

The outside radius of the pope is,

The wall thickness of the pope can be calculated as,

Therefore, the wall thickness of the pope is t=0.358 in.

this is a combination, so

We have to solve for c:

When we have quadratic expressions, we have to take into account that each number has two possible square roots: one positive and one negative.

We can see it in this example: the square root of 4 can be 2 or -2. This is beacuse both (-2)² and 2² are equal to 4.

Then, taking that into account, we can solve this expression as:

We then calculate the first solution for the negative value -8:

And the second solution for the positive value 8:

Then, the two solutions are c = -17 and c = -1.

We can check them replacing c with the corresponding values we have found:

Both solutions check the equality, so they are valid solutions.

Answer: -17 and -1.

The amount Andrew have to pay to buy 4 pounds of walnuts = $19

The expression for the cost to buy p pounds of walnuts= 4p - 1

Explanation:

Amount per pound of walnut = $4

Amount of coupon = $1

The cost of 4 pounds of walnuts:

The amount Andrew have to pay to buy 4 pounds of walnuts:

Amount = cost - coupon

Amount = $20 - $1

The amount Andrew have to pay to buy 4 pounds of walnuts = $19

The expression for the cost to buy p pounds of walnuts:

let number of pounds = p

Cost for p pounds of walnut = Amount per walnut * number of walnut

Cost for p pounds of walnut = $4 * p

= $4p

The expression for the cost to buy p pounds of walnuts= cost for p - coupon

= 4p - 1

Considering the given dot plot for the distribution, it is found that:

a) The distribution is right skewed.

b) There is an outlier at 9.

c) Since there is an outlier, the best measure of center is the median.

A dot plot shows the number of times that each measure appears in the data-set, hence the data-set is given as follows:

1, 1, 1, 1, 2, 2, 2, 2, 2 3, 3, 3, 3, 4, 4, 4, 5, 5, 5, 9.

To find the skewness of the data-set, we need to find the mean and the median.

The mean is the sum of all values divided by the number of values of 20, hence:

Mean = (4 x 1 + 5 x 2 + 4 x 3 + 3 x 4 + 3 x 5 + 9)/20 = 3.1.

The median is the mean of the 9th and the 10th elements(even cardinality) of the data-set, hence:

Median = (2 + 3)/2 = 2.5.

The mean is greater than the median, hence the distribution is right skewed.

To identity outliers, we need to look at the quartiles, as follows:

The interquartile range is:

IQR = 4 - 2 = 2.

Outliers are more than IQR from the quartiles, hence:

4 + 1.5 x 2 = 4 + 3 = 7 < 9, hence 9 is an outlier in the data-set, and hence the median will be the best measure of center.

The questions are as follows:

Part A: Describe the dotplot. (4 points)

Part B: What, if any, are the outliers in these data? Show your work. (3 points)

Part C: What is the best measure of center for these data? Explain your reasoning. (3 points) (10 points)
