Answer:

A) The graph shifts 4 units up.

Step-by-step explanation:

It is written partially in Slope-Intercept Form [y = mx + b]. That 4 is your y-intercept, which means it is shifted upward; it is written as [0, 4], but at least you get the idea.

I am joyous to assist you anytime.

There is a total of 2,512 people attending the fun fair. 5/8 of sttemdees are students and 1/4 of attendees are parents. the res

Answer:

314 of the people attending the fun fair are people living in the neighborhood

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Number of people attending the fun fair = 2,512

Fraction of people attending the fun fair that are students = 5/8

Fraction of people attending the fun fair that are parents = 1/4

Rest of the people attending the fun fair lives in the neighborhood

2. Let's calculate the number of students, parents and people living in the neighborhood

Students:

Fraction of people attending the fun fair that are students = 5/8

5/8 * 2,512 = 1,570

1,570 of the people attending the fun fair are students

Parents:

Fraction of people attending the fun fair that are parents = 1/4

1/4 * 2,512 = 628

628 of the people attending the fun fair are parents

People living in the neighborhood

2,512 - 1,570 - 628 = 314

314 of the people attending the fun fair are people living in the neighborhood

The standard deviation for a set of data is 6.5. The mean is 255. What is the Margin of Error?

HACTEHA [7]

Answer: The margin of error is 12.74.

Step-by-step explanation:

Since we have given that

Standard deviation = 6.5

Mean = 255

Let 95% level of significance,

So, z value = 1.96

We need to find the "Margin of error":

So, it becomes :

Margin of error = Standard deviation × z-value

Margin of error = $6.5\times 1.96=12.74$

Hence, the margin of error is 12.74.

Find cos(2*ABC) 100POINTS

juin [17]

Answer:

$-\dfrac{7}{25}$

Step-by-step explanation:

Trigonometric Identities

$\cos(A \pm B)=\cos A \cos B \mp \sin A \sin B$

Trigonometric ratios

$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$

where:

$\theta$ is the angle
O is the side opposite the angle
A is the side adjacent the angle
H is the hypotenuse (the side opposite the right angle)

Using the trig ratio formulas for cosine and sine:

$\cos(\angle ABC)=\dfrac{3}{5}$

$\sin(\angle ABC)=\dfrac{4}{5}$

Therefore, using the trig identities and ratios:

$\begin{aligned}\implies \cos(2 \cdot \angle ABC) & = \cos(\angle ABC + \angle ABC)\\\\& = \cos (\angle ABC) \cos (\angle ABC) - \sin(\angle ABC) \sin (\angle ABC)\\\\& = \cos^2(\angle ABC)-\sin^2(\angle ABC)\\\\& = \left(\dfrac{3}{5}\right)^2-\left(\dfrac{4}{5}\right)^2\\\\& = \dfrac{3^2}{5^2}-\dfrac{4^2}{5^2}\\\\& = \dfrac{9}{25}-\dfrac{16}{25}\\\\& = \dfrac{9-16}{25}\\\\& = -\dfrac{7}{25} \end{aligned}$

Find the fractional part of a circle corresponding to 144 degrees

ruslelena [56]

If you change the percentage to a decimal fraction then Multiply 360 *the number of degrees in a circle* by the decimal fraction. The result is the angle measure of your pie slice For example, 10% would be a 36 degree angle. 25% would be a 90 degree angle. 17.5% would be 360 times .175 = 63 degrees
