Answer: 8i

Answer:

Step-by-step explanation:

The answer is c! :)

Answer:

The answer is B. 31, 29, 44, 28.

Step-by-step explanation:

1 lote = 5/8 cup yellow + 5/8 cup blue

29 lotes = 29(5/8) +29(5/8) cups

29 lotes = 58(5/8)= (58*5)/8=290/8=145/4

145/4 =35.25 cups of paint

We have that the sample consist in n=13 students. The percentile formula is given by

where x denotes the percentaje. In the first case, p=38, then, we have

then, we get

that is, P_38 corresponds to 41 miles driven.

In the second case, by substituting x=60 in our formula, we get

which gives

that is, P_60 corresponds to 56 miles driven.

Then, the answers are:

This means that approximately 38% of the data lie below 41, when the data are ranked.

This means that approximately 60% of the data lie below 56, when the data are ranked.

Given data:

The given points are (5, 4) and (-1, 14).

The distance between the given points is,

Thus, the distance between the given points is 2√(34).

Hello there. To solve this question, we need to remember some properties about quadratic functions and its key features.

Let f(x) = ax² + bx + c, for a not equal to zero.

The main key feature we can see at first glance is the leading coefficient a.

If a < 0, the parabola (the graph of the function) will have its concavity facing down.

If a > 0, the parabola will have its concavity facing up.

It also means the function will have either a maximum or a minimum point on its vertex, respectively.

Another key feature of the function is the y-intercept, i. e. the point in which the x-coordinate is equal to zero, is (0, c).

The x-intercepts of the graph (in plural), are the roots of the function.

If b² - 4ac > 0, we'll have two distinct real roots.

If b² - 4ac = 0, we'll have two equal real roots.

If b² - 4ac < 0, we'll have two conjugate complex roots (not real roots)

This b² - 4ac is the discriminant of the function.

The roots can be found by the formula:

x = (-b +- sqrt(b² - 4ac))/2a

The vertex of the graph can be found on the coordinates (xv, yv), in which xv is calculated by the arithmetic mean of the roots

xv = ((-b + sqrt(b²-4ac))/2a + (-b-sqrt(b²-4ac))/2a)/2 = -b/2a

The yv coordinate can be found by plugging in xv in the function

yv = a(-b/2a)² + b(-b/2a) + c, which will be equal to -(b²-4ac)/4a.

The marginal error is 0.0240

The 95% confidence interval for the proportion of all student athletes in this country have been subjected to some form of hazing is (0.576, 0.624).

Given,

The percentage of students surveyed = 60%

Number of athletes = 1600

Confidence interval = 95%

We have to find the marginal error and 95% confidence interval of the study;

The following results are obtained from a sample of n people that were surveyed, with a probability of success of  π and a level of confidence of 1 - ∝

π ± z [tex]\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]

Where,

z is the z score with a p value of 1 - ∝/2

Here we have,

n = 1600 and π = 0.6

95% confidence level

So ∝ = 0.05 , z is the value of Z that has a pvalue of  1 - 0.05/2 , so Z = 1.96.

Then, the margin of error is;

M = [tex]z\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]

M = [tex]1.96\sqrt{\frac{0.6.0.4}{1600} }[/tex]

M = 0.0240

M = 2.40 percentage points.

Lower limit of the interval;

π - M = 0.6 - 0.0240 = 0.576

Upper limit of the interval;

π + M = 0.6 + 0.0240 = 0.624

The 95% confidence interval for the proportion of all student athletes in this country have been subjected to some form of hazing is (0.576, 0.624).

Triangles' resemblance is reflected by their congruence. If the matching sides and angles of two triangles match, the triangles are said to be congruent.

For triangles, there are five primary congruency rules: Side-Side-Side is an SSS criterion. The side-angle-side SAS criterion. Angle, Side, Angle is an ASA criterion. Angle-Angle-Side is an AAS criterion.

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

An isosceles triangle in geometry is one with at least two equal-length sides. It is sometimes stated as having exactly two equal-length sides and other times as having at least two equal-length sides, with the latter version adding the equilateral triangle as one of the possible configurations.

To find:

Where has the point moved to?

Explanation:

It is given that,

Starting at 0 on a number line, a point is moved 21 units, then 53 units, then 721 units, and finally negative-50 units.

That implies,

Since starting at 0 on a number line, a point is moved 21 units.

Then,

Also, then 53 units.

Then,

If 19% say that math is their favorite subject, with a margin of error of 2.5%, then the confidence of interval is:

b) The confidence of interval is the range of values in which you think the study or the values are going to fall between if anyone redo the study, it doesn't contain the margin of error because this percentage means the probability that the values aren't going to fall between the confidence of interval.

The above result is equivalent to:

w= -7

Explanation

Step 1

The addition property of equality and subtraction property of equality are similar. Adding or subtracting the same number to or from both sides of an equation keeps both sides equal, so we can use this fact to isolate w

a) subtract 6 in both sides of the equation

Step 2

The division property of equality states that when we divide both sides of an equation by the same number, the two sides remain equal.so

b) divide both sides by 4

By using the given zeros, we will see that the simplest polynomial is:

p(x) = x^3 - 7x - 6

So the correct option is the second one.

Remember that the first simplest polynomial with the zeros x₁, x₂, x₃, ..., xₙ, is written as:

p(x) = (x - x₁)*(x - x₂)*...*(x - xₙ)

Here we have only 3 zeros, which are -1, -2, and 3, then we can write:

p(x) = (x - (-1))*(x - (-2))*(x - 3) = (x + 1)*(x + 2)*(x - 3)

Expanding the polynomial we get:

p(x) =  (x + 1)*(x + 2)*(x - 3)

p(x) =  (x^2 + x + 2x + 2)*(x - 3)

p(x) = (x^2 + 3x + 2)*(x - 3)

p(x) = x^3 + 3x^2 + 2x - 3x^2 - 9x - 6

p(x) = x^3 - 7x - 6

Then the correct option is the second one.
