Answer:

I would say C Sets 2 and 3 contain outliers.

Step-by-step explanation:

Set 2 has an outlier of 90, and set 3 contains an outlier of 40. 40 is not as much of an outlier as 90, so I'm not absolutely sure.

Answer:

-Sets 2 and 3 contain outliers.

Step-by-step explanation:

Mean is the average value of the set. Mean deviation is the difference of the values of the set when compared to the mean.

In set 1 the values are between 50 and 60. This means that the mean will also be between 50 and 60.

In set 2 there is one outlier that is 38. So, the range of the values are between 38 and 90. More values are between 30 and 40 so the mean will be in this range. So (90 - the mean in the range between 30 and 40) will be a large number.

The same goes for set 3.

3(x - 4) + 9 = 18<br><br> Step by step (and explanation)

Andrews [41]

Answer:

= 7

Step-by-step explanation:

3(x−4)+9=18

3 − 1 2 + 9 = 1 8

3 − 3 = 1 8

3 = 1 8+3

3 = 21

x= 21/3

x=7

Julli [10]

Answer:

Markus has 6 marbles in each bag.

Step-by-step explanation:

Markus has 18 marbles and 3 bags

If you divide 18 marbles by 3 bags that would be 6 marbles in each bag.

Find an equation of the line that passes through (4,5) and that line is parallel to y=3x+2. Give the answer in slope-Intercept f

rodikova [14]

Answer:

y = 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with m = 3

Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = 12 + c ⇒ c = 5 - 12 = - 7

y = 3x - 7 ← equation of line

A support wire extends from the top of a 225 feet radio tower to the ground and makes an angle of 64° with the ground. How long

aniked [119]

Answer:

250.34 feet

Step-by-step explanation:

Find attached to this answer and appropriate diagram.

From this question, we can see that this is a trigonometric function

The height of the radio tower = 225 feet = Opposite side

θ = Angle 64°

In the question we are told to find the length of the wire needed to reach from the top of the tower to the ground.

From the attached diagram, we can see that that is equivalent to finding the hypotenuse.

Hence, we are using the Trigonometric function of Sine.

sin θ = Opposite side/ Hypotenuse side

sin 64 = 225 feet/ Hypotenuse

Cross multiply

sin 64 × Hypotenuse = 225 feet

Divide both sides by sin 64

Hypotenuse = 225 feet / sin 64

Hypotenuse = 250.33543661 feet

Approximately = 250.34 feet

Therefore, the length of the wire needed to reach from the top of the tower to the ground is 513.3 feet.
