Jessica got back an exam and she earned 95 out of 100 points. Is her score an example of a raw score or a transformed score?

Answers

Answer 1

Answer:

Raw Score

Step-by-step explanation:

A raw score is a datum point or value that has not been altered in any way. Raw scores are original measurements from surveys, tests, or other instruments that have not been weighted, transformed, or converted into any other form. Raw scores are also called observed scores.

Therefore

It is a Raw score

A map has a scale in which 1.25 inches represents 250 miles.

How many miles does 1 inch represent?

Answers

Answer:  200 miles

Work Shown:

(1.25 inches)/(250 miles) = (1 inch)/(x miles)

(1.25)/(250) = 1/x

1.25x = 250*1 ..... cross multiplication

1.25x = 250

x = 250/(1.25)

x = 200 miles

what is the length of a rectangular solid with a volume of 180 cu ft, if it is 9 ft high and 4ft wide?

Answers

Answer:

5 ft

Step-by-step explanation:

The formula for Volume is V=lwh, or Volume = length x width x height.

The equation would be:

[tex]180=l(4)(9)[/tex]

or

[tex]180=36l[/tex]

To find the answer, divide by 36.

[tex]\frac{180}{36} =\frac{36l}{36}[/tex]

1+log2=log(x+1)

I know that x=19 but how do you get 19?

Answers

Recall that [tex]\log 10 = 1[/tex] so we can rewrite the equation above as

[tex]\log 10 + \log 2 = \log (x + 1)[/tex]

Also recall that [tex]\log(ab) = \log a + \log b[/tex] so the left-hand side becomes

What are the zeroes of f(x) = x2 - X - 2?
x= -2,1
x = 2, -1
x= -2, -1
x = 2,1

Answers

Answer:

x=2    x=-1

Step-by-step explanation:

f(x) = x^2 - X - 2

0= x^2 -x-2

Factor

0 =(x-2)(x+1)

Using the zero product property

x-2 =0   x+1 =0

x=2    x=-1

Answer:

x=2, -1

Step-by-step explanation:

Hi there!

We want to find the zeros of this function: f(x)=x²-x-2

The zeros are the values of x that will make f(x)=0

So that means in order to find the zeros, set f(x) as 0

In that case,

x²-x-2=0

Now let's solve the quadratic equation

We can do it by factoring

-x is the sum of two numbers, while -2 is the product of those two same numbers

Now think: which two numbers add up to -1, but multiply to get -2?

Those numbers are -2 and 1

Now factor the polynomial by FOIL:

(x-2)(x+1)=0

Split and solve

x-2=0

x=2

x+1=0

x=-1

The zeros are x=2, -1

Hope this helps!

Which of the binomials below is a factor of this trinomial?
x^2+8x+16

Answers

Answer:  x+4

This is because the given expression factors to (x+4)(x+4), which condenses to (x+4)^2.

To factor, think of two numbers that A) multiply to 16, and B) add to 8. Those values would be 4 and 4

4+4 = 8

4*4 = 16

So that's how we end up with (x+4)(x+4). You can use the FOIL rule to expand that out and get x^2+8x+16 again to help verify you have the correct factorization.

Answer:

rightacuteobtuserightobtuse

Step-by-step explanation:

When the same problem is repeated, I like to solve it using a spreadsheet. That way, the formulas only need to be entered once, and the arithmetic is (almost) guaranteed to be done correctly.

A "form factor" computed from side lengths can be used to determine the type of triangle. Where 'c' is the long side, that factor can be computed as ...

  f = a² +b² -c²

and interpreted as follows:

f = 0, right trianglef > 0, acute trianglef < 0, obtuse triangle

(The sign of f matches the sign of the cosine of the largest angle computed using the law of cosines.)

Of course, a right triangle can also be identified by looking at the slopes of the sides of the triangle. If any pair of slopes has a product that is -1, or if any pair is 0 and "undefined", then the triangle will be a right triangle.

__

The attached spreadsheet is designed to accommodate a number of different problem requirements. It shows both side lengths and slopes, and it shows the "form factor" as described above. The final classification is shown at far right.

A town recently dismissed 8 employees in order to meet their new budget reductions. The town had 9 employees over 50 years of age and 16 under 50. If the dismissed employees were selected at random, what is the probability that at least 7 employees were over 50? Express your answer as a fraction or a decimal number rounded to four decimal places.

Answers

Answer:

The probability that at least 7 employees were over 50 is 0.0073%.

Step-by-step explanation:

Given that a town recently dismissed 8 employees in order to meet their new budget reductions, and the town had 9 employees over 50 years of age and 16 under 50, if the dismissed employees were selected at random, to determine what is the probability that at least 7 employees were over 50, the following calculation must be performed:

9/25 x 8/24 x 7/23 x 6/22 x 5/21 x 4/20 x 3/19 = X

0.36 x 0.33 x 0.304 x 0.272 x 0.238 x 0.2 x 0.157 = X

0.000073 = X

100X = 0.0073

Therefore, the probability that at least 7 employees were over 50 is 0.0073%.

A technology company is forming a task force of six members to deal with urgent quality issues. The positions will be filled by randomly chosen qualified applicants. The qualified applicants consist of five managers and ten engineers.

Required:
a. What is the probability that the chosen applicants are either all managers or all engineers?
b. What is the probability that the number of managers is the same as the number of engineers on the task force?
c. What is the expected number of engineers chosen?
d. What is the probability that at least one manager is chosen for the task force?

Answers

Answer:

a. 0.042 = 4.2% probability that the chosen applicants are either all managers or all engineers.

b. 0.2398 = 23.98% probability that the number of managers is the same as the number of engineers on the task force.

c. The expected number of engineers chosen is 4.

d. 0.958 = 95.8% probability that at least one manager is chosen for the task force.

Step-by-step explanation:

The positions are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

5 + 10 = 15 applicants, which means that [tex]N = 15[/tex]

10 are engineers, which means that [tex]k = 10[/tex]

Six members are chosen, which means that [tex]k = 6[/tex]

a. What is the probability that the chosen applicants are either all managers or all engineers?

Not possible having all managers(five applicants are manager, while there are 6 open positions), so this is P(X = 6), that is, all engineers.

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 6) = h(6,15,6,10) = \frac{C_{10,6}*C_{5,0}}{C_{15,6}} = 0.042[/tex]

0.042 = 4.2% probability that the chosen applicants are either all managers or all engineers.

b. What is the probability that the number of managers is the same as the number of engineers on the task force?

3 engineers, so this is P(X = 3).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,15,6,10) = \frac{C_{10,3}*C_{5,3}}{C_{15,6}} = 0.2398[/tex]

0.2398 = 23.98% probability that the number of managers is the same as the number of engineers on the task force.

c. What is the expected number of engineers chosen?

The expected value of the hypergeometric distribution is:

[tex]E(X) = \frac{nk}{N}[/tex]

So

[tex]E(X) = \frac{6(10)}{15} = 4[/tex]

The expected number of engineers chosen is 4.

d. What is the probability that at least one manager is chosen for the task force?

At most five engineers, which is:

[tex]P(X \leq 5) = 1 - P(X = 6)[/tex]

Since in item a. we already have P(X = 6).

[tex]P(X \leq 5) = 1 - 0.042 = 0.958[/tex]

0.958 = 95.8% probability that at least one manager is chosen for the task force.
