Answer:  standard deviation = 8

This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".

Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.

Answer:

This isn't really a math problem since there aren't many numbers or variables provided to create an equation. So Chelsea can complete her homework in any order of her choice, but I would say that she should complete the homework that's due first before moving onto the more recent homework that was given.

Answer:

i = Could be true (C)

ii = False (F)

iii = Definitely true (D)

[tex]\theta[/tex] is in quadrant II

Step-by-step explanation:

Given

[tex]\sin(\theta) > 0[/tex] and [tex]\cos(\theta) < 0[/tex]

Required

Where is [tex]\theta[/tex]

[tex]\sin(\theta) > 0[/tex] and [tex]\cos(\theta) < 0[/tex] imply that

[tex]\theta[/tex] is in quadrant II

Because that is only quadrant where [tex]\sin(\theta) > 0[/tex] and [tex]\cos(\theta) < 0[/tex] exist.

Answer:

Quadrant II

Answer:

1) 60

3) 120

4) 60

Step-by-step explanation:

Angle 1 is supplementary to your known angle. Therefor, Angle 1 is 180 - 120

Angle 3 is supplementary to Angle 1 and equal to 120

Angle 4 is supplementary to Angle 3 and equal to angle 1.

Answer:

x = 90

Step-by-step explanation:

This will add up to 360 degrees in total

90 + 90 + 90 + 90 = 360 therefore x = 90 Hope that helps!

Answer:

[tex]\boxed {\boxed {\sf z=2.8}}[/tex]

Step-by-step explanation:

The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:

[tex]z= \frac{x- \bar x}{s}[/tex]

where x is the value, x-bar is the mean, and s is the standard deviation.

We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.

Substitute the values into the formula.

[tex]z= \frac{ 39-25}{5}[/tex]

Solve the numerator.

[tex]z= \frac{ 14}{5}[/tex]

[tex]z=2.8[/tex]

The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.

Answer:

The 1st you show is an expositional decay.

Step-by-step explanation:

If you notice it is a declining power of 2

y = 2**(5-x) which is nonlinear

The 2nd is an arithmetic decline (constant decline) and the 3rd is a geometiric decline (constant ratio).

Area = 1/2 × NMP angle in radian × radius^2

Area = 1/2 × ( 40pi /180 ) × 12^2

Area = 1/2 × ( 2pi / 9 ) × 144

Area = 1/2 × 144 × ( 2 × 3.14 / 9 )

Area = 72 × 0.697

Area = 50.184

Area = 50.18 cm^2

Answer:

4-36 = -32

-32 + 180 = 148

Therefore | x = 148

I hope I helped! :)

Answer:

148

Step-by-step explanation:

=> -32=x-180

=> -32+180=x

=> 148=x

The inequality that represents the following graph is C. x > -4

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

An inequality is a mathematical statement which compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to show relationships between quantities or to express constraints or conditions.

The inequality that represents the graph;

x > -4x>−4x, is greater than, minus, 4

x > -4

Answer:

Length of leg of triangle =  

Step-by-step explanation:

We are given a 45°-45°-90° triangle with hypotenuse measuring 18 cm.

Let us assume the following labeling of the diagram, as attached in the answer area.

The two angles here are equal to 45° so two sides of the triangle opposite to the equal angles will also be equal to each other i.e. it is an isosceles triangle.

i.e. The sides XY and YZ will be equal.

Let XY = YZ = x cm

It is known that in a right angled triangle, pythagorean theorem holds well.

As per pythagoream theorem:

Putting the values:

So, the length of leg of triangle =
