Answer:

Option C: skewed right

Step-by-step explanation:

Option A : Skewed left

Definition: A fewer data plots are found to the left of the graph (toward the smaller numeric values).

The "tail" of the graph is pulled toward the lower or negative numbers, or to the left.

Since in the given graph fewer data plots are given on the right and the tail of the graph is also pulled toward the right .So, it is not left skewed .

Since it does not satisfy the definition of skewed left .

So, Option A is wrong.

Option B: bell-shaped

Definition: When graphed, a vertical line drawn at the center will form mirror images with the left half of the graph being the mirror image of the right half .

In the histogram and dot plot, this shape is referred to as being a "bell shape"

Since the given image does not satisfy the definition of bell shaped .

So, Option B is wrong .

Option C: skewed right

Definition: The fewer data plots are found to the right of the graph (toward the larger numeric values). The "tail" of the graph is pulled toward higher positive numbers, or to the right.

Since in the given graph fewer data plots are given on the right and the tail of the graph is also pulled toward the right .So, it is right skewed.

Hence Option C is correct . The given graph is skewed right .

Option D: uniform

Definition: The data is spread equally across the range.

Since the given graph does not satisfy the definition of uniform graph

So, Option D is wrong .

6 · e^(4x - 2) = 3
     e^(4x - 2) = .5
 ln e^(4x - 2) = ln (.5)
          4x - 2 = ln (.5)
               4x  = ln (.5) + 2

The Z-score is based on the concept of the normal distribution, the fact that we can expect 95% of the values in the distributio
Dennis_Churaev [7]

Answer:

C.) In perfect health.

Step-by-step explanation:

Given an average weight of 15kg and a standard deviation of 3kg for children of 4 years. Since the weight is based on a normal Z - distribution of 95% which is mean ± 2(standard deviations)

Mean weight interval is :

15 - 2(3) ; 15 + 2(3)

(9 ; 21) ; this weight interval could be interpreted to mean the normal or perfect weight value.

Therefore, given that the child weighs 12kg

Since, 12 kg falls within in the interval, we can conclude that the child is in perfect health.

What is the slope of a line perpendicular to the line whose equation is 3x+6y=-183x+6y=−18. Fully reduce your answer.
schepotkina [342]

Answer:

2

Step-by-step explanation:

The given equation of line is

3x+6y=-18

We need to find the slope of a line which is perpendicular to the given line.

The given equation can be rewritten as

3x+6y+18=0      ...(i)

If a line is defined as ax+bx+c=0, then the slope of the line is  

m=-\dfrac{a}{b}

In equation (i), a=3, b=6 and c=18. So, slope of the line is

m_1=-\dfrac{3}{6}=-\dfrac{1}{2}

Let m_2 be the slope of perpendicular line.

We know that product of two perpendicular line is -1.

m_1\cdot m_2=-1

(-\dfrac{1}{2})\cdot m_2=-1

Multiply both sides by -2.

m_2=2

Therefore, the slope of perpendicular line is 2.

Find the volume of a pyramid with a square base, where the perimeter of the base is 16.9\text{ cm}16.9 cm and the height of the
worty [1.4K]

Answer:

Volume of square based pyramid = 116.62 cm³

Step-by-step explanation:

Given:

Perimeter of square base = 16.9 cm

Height of pyramid = 19.6 cm

Find:

Volume of square based pyramid

Computation:

Perimeter of square base = 16.9 cm

4[Side] = 16.9

Side = 4.225 cm

Area of square = Side x Side

Area of square = 4.225 x 4.225

Area of square = 17.85 cm²

Volume of square based pyramid = [Area of square][Height of pyramid] / 3

Volume of square based pyramid = [17.85][19.6] / 3

Volume of square based pyramid = 349.86 /3

Volume of square based pyramid = 116.62 cm³
