Mark walked 12 1/2 miles in 5 hours. How many miles did Mark walk in 1 hour?

Answers

the answe is it is 2.5 or 2 1/2 as he said but in conclusion answe 2 1/2 or 2 and 1 half

Distance can be defined as how far a person or an object can go or cover.

The number of miles Mark walked in 1 hour is [tex]2\frac{1}{2}[/tex] miles

From the question,

In 5 hours, Mark walked a distance of 12 1/2 miles.

Hence,

5 hours = [tex]12\frac{1}{2}[/tex] miles

1 hour = ?

Cross Multiply

1 hour x [tex]12\frac{1}{2}[/tex] miles / 5 hours

= [tex]2\frac{1}{2}[/tex] miles

The number of miles Mark walked in 1 hour is [tex]2\frac{1}{2}[/tex] miles

The Stanford-Binet Intelligence Scale is an intelligence test, which, like many other IQ tests, is standardized in order to have a normal distribution with a mean of 100 and a standard deviation of 15 points.

As an early intervention effort, a school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder.

Determine the margin of error,
, of a 90% confidence interval for the mean IQ score of all students with the disorder. Assume that the standard deviation IQ score among the population of all students with the disorder is the same as the standard deviation of IQ score for the general population, =15

points.

Give your answer precise to at least two decimal places.

Answers

Answer:

4.11

Step-by-step explanation:

Margin of error equals critical value times standard error.

MoE = CV × SE

For 90% confidence and n > 30, the critical value is z = 1.645.

The standard error is SE = σ/√n = 15/√36 = 2.5.

Therefore, the margin of error is:

MoE = (1.645) (2.5)

MoE = 4.11

The margin of error of a 90% confidence interval for the mean IQ score of all students with the disorder is 4.1125 and this can be determined by using the formula of margin of error.

Given :

Standardized in order to have a normal distribution with a mean of 100 and a standard deviation of 15 points.A school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder.90% confidence interval.

According to the given data, the confidence is 90% and n > 30, so the critical value is z = 1.645.

Now, to determine the standard error using the below formula:

[tex]\rm SE = \dfrac{\sigma}{\sqrt{n} }[/tex]

[tex]\rm SE = \dfrac{15}{\sqrt{36} }=\dfrac{15}{6}[/tex]

SE = 2.5

Now, the formula of margin of error is given by:

[tex]\rm MOE = z\times SE[/tex]

MOE = (1.645) [tex]\times[/tex] (2.5)

MOE = 4.1125

So, the margin of error is 4.1125.

The figure shows a pair of parallel line segments on a coordinate grid: the line segments are translated 2 units to the left to form J’K and M’N. Which statement describes J’K and M’N

Answers

Answer:

Step-by-step explanation:

Answer:

Line segments J'K' and M'N' do not intersect and are the same distance apart as JK and MN.

Step-by-step explanation:

If the line segments are translated 2 units to the left, then JK will start at (1, -1) and go to (5, -1), and MN will start at (1, -2) and to to (5, -2). So the line segments remain parallel and the same distance apart.

f(x)=-3x^2-6x

Find f(−9)

Answers

Answer:

f(-9)= -189

Step-by-step explanation:

f(-9)= -3(-9)^2-6(-9)

f(-9)= -3(-9)^2 +54

f(-9)= -3(81) +54

f(-9)= -243 + 54

f(-9)= -189

[tex]f(-9)[/tex] is [tex]-189[/tex]

What is function?

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.

According to question, we have the function [tex]f(x)=-3x^2-6x[/tex]

We have to find [tex]f(-9)[/tex]

So, [tex]f(-9)=-3[/tex]×[tex](-9)^{2}[/tex][tex]-6(-9)[/tex]

[tex]=-243+54[/tex]

[tex]=-189[/tex]

Hence, we can conclude that [tex]f(-9)[/tex] is [tex]-189[/tex]

Chan receives a bonus from his job. He pays 30% taxes, pays 30% charity and 25% debt. Has $600 remaining from his bonus. What was the total amount of chains bonus?

Answers

Answer:

b = $4000

Step-by-step explanation:

Let b represent the bonus amount.

Then the bonus, b, less the three deductions, is represented by

b - 0.30b - 0.30b - 025b, and this comes to $600. Find the value of b.

b - 0.85b = $600, or

0.15b = $600

Then b = $4000

What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

To bake 100 of his favorite cookies, Mr.Wallis needs 350 grams of sugar.

Let x be the amount of sugar for 10 cookies.

The number of grams of sugar would he need to bake 10 cookies will be

x / 10 = 350 / 100

x / 10 = 3.5

x = 35 grams

The number of grams of sugar would he need to bake 10 cookies will be 35 grams.

Dam.In all the history of scientific discovery there has never been, perhaps, so general, rapid, and dramatic an effect wrought on the scientific centres of Europe as has followed, in the past four weeks, upon an announcement made to the Wrzburg Physico-Medical Society, at their December meeting, by Professor William Konrad Rntgen, professor of physics at the Royal University of Wrzburg. The first news which reached London was by telegraph from Vienna to the effect that a Professor Rntgen, until then the possessor of only a local fame in the town mentioned, had discovered a new kind of light, which penetrated and photographed through everything. This news was received with a mild interest, some amusement, and much incredulity; and a week passed. Then, by mail and telegraph, came daily clear indications of the stir which the discovery was making in all the great line of universities between Vienna and Berlin. Then Rntgen's own report arrived, so cool, so business-like, and so truly scientific in character, that it left no doubt either of the truth or of the great importance of the preceding reports. . . .Exactly what kind of a force Professor Rntgen has discovered he does not know. As will be seen below, he declines to call it a new kind of light, or a new form of electricity. He has given it the name of the X rays.Which statement correctly describes how the central idea of this excerpt is developed?
