True or false? A histogram and a relative frequency histogram, constructed from the same data, always have the same basic shape.

Choose the correct answer below. O A. False. The two histograms can have very different shapes depending on the distribution of the data. O C. False. The histograms use different scales on the y-axis, resulting in completely different shapes. O B. True. They will both have the same shape and the same vertical scale. They will dffer only in the scale used on the horizontal axis. O D. True. A relative frequency histogram will have a different scale on the y-axis but the same shape as a regular histogram.

Answer:

A. False

C. False

B. False

D. True

Step-by-step explanation:

Frequency histogram is denote the actual frequency of each observation or different class- intervals whereas Relative frequency distribution shows the fraction of that frequency to the total frequencies or the percent of that frequency to the total.

Thus the shape of both histogram are same.

A. False.

C. False

Since, Scale of the y-axis is different. But they has same shape.

B. False

Since, vertical scale is different for both histogram and horizontal scale is same.

D. True

On a map, the scale shown is 1 inch : 3 miles. If an island is 0.5 square inches on the map, what is the actual area of the isla
gtnhenbr [62]

Answer:

4.5

Step-by-step explanation:

First we need to turn the ratio of 1 : 3 into a fraction

1:3 = 1/3

Next we need to square that fraction

1 x 1 = 1

3 x 3 = 9

Then we turn those numbers into a fraction

1/9

We turn the .5 into a fraction

.5/x

And cross multiply both fraction by each other

1/9 x .5/x

1 x X = X

9 x .5 = 4.5

So

4.5 = X

The point (5,4) is rotated 180° clockwise
zmey [24]

Answer:  (-5,-4)

Step-by-step explanation:

I assume that you need the new coordinates of the point after the rotation centered at the origin.

For this exercise it is important to remember the definition of "Rotation".

A Rotation is defined as a transformation which a figure is rotated about a fixed point known as "Center of rotation".

The figure before the transformation is called Pre-Image and the figure obtained after the transformation is called "Image".

The 180 degree rotation about the origin Rule states that:

(x,y) → (-x, -y)

Therefore, knowing that the given point (5,4) is rotated 180 degrees clockwise about the origin, you can conclude that its Image is:

(-5,-4)

2. On December 31, Juan Carlos made a $ 7,000 deposit in an account that pays 2.975% interest compounded semi-annually. How much
inna [77]

Answer:$ 7425.89

Step-by-step explanation:

Formula to find the compound amount ( compounded semiannually) :-

A=P(1+\dfrac{r}{2})^{2n} , where P is the principal amount, r is rate of interest ( in decimal), and n is time in years.

Given : P= $7000

r=2.975%=0.02975

Time : n= 2

Then, The amount in account after 2 years:-

A=7000(1+\dfrac{0.02975}{2})^{2\times2}\\\\=7425.88565609\approx7425.89

Hence, Amount in account after 2 years = $ 7425.89
