The dot plot shows the weekly biking times (in hours). What are the most appropriate measures to describe the center and variati

on? Find the measures you chose. Round to the nearest tenth, if necessary.
The distribution is
symmetric
. So, the
is the most appropriate measure to describe the center, and the
mean absolute deviation
is the most appropriate measure to describe the variation.

The measure of center of the data is
hours.

The measure of variation of the data is
hours.

Margaret [11]

Answer:

Amina practices the piano for 54 minutes each week.

Step-by-step explanation:

45% * 120min = 0.45 * 120min = 9/20 * 120min = 9 * 6min = 54min

Find the area of the shaded region in the graph y=x^2-2
Artist 52 [7]

By applying the concept of <em>definite</em> integral and the given restrictions, we conclude that the area of the <em>shaded</em> region in the graph is - 11/12.

<h3>How to find the area of the shaded region in the graph y = x² - 2</h3>

The area below the curve can be found by using <em>definite</em> integrals, which is defined here in this form:

I = \int\limits^{1.5}_{0.5} {x^{2}-2} \, dx     (1)

Now we proceed to calculate the area:

I = \int\limits^{1.5}_{0.5} {x^{2}} \, dx - 2 \int\limits^{1.5}_{0.5}\, dx

I = \frac{x^{3}}{3}|_{0.5}^{1.5} - 2 \cdot x |_{0.5}^{1.5}

I = \frac{1.5^{3}-0.5^{3}}{3} - 2 \cdot (1.5 - 0.5)

I = -\frac{11}{12}

By applying the concept of <em>definite</em> integral and the given restrictions, we conclude that the area of the <em>shaded</em> region in the graph is - 11/12.

<h3>Remark</h3>

The statement is incomplete. Complete form is shown below:

Find the area of the shaded region in the graph y = x² - 2, between x = 0.5 and x = 1.5

-3y(-4y)=32+(x^0+y^0)^5
docker41 [41]
Any number to the power of 0 equals 1. So, we can rewrite the equation as follows:
12y=32+2^{5}=32+32=64
y=\frac{64}{12}=5\frac{1}{3}

A father’s age now is three times the age that his son was 4 years ago. In
Mice21 [21]
Let ‘s’ be the son’s age 12 years ago.
Let ‘f’ be the father’s current age.

4 years ago, the son was:

s-4

So, his father is currently:

3(s-4)

=

3s-12

Therefore:

f = 3s-12

In twelve years, the son will be:

s+12

And the father will be:

f+12

This can also be written as:

3s-12+12 as the fathers younger age would be f = 3s+12

=

3s

So, we know that s+12 is half the fathers current age, meaning the father is currently 2(s+12) which is equivalent to 2s+24. Also, we know that the father is currently 3 times the sons age 12 years ago, so 3s (proven by the calculations we made above). Therefore, 2s+24=3s which means 24=s. We can then substitute this, and we will receive 24+12 = 36

Son’s current age: 36

We then substitute the son’s age 12 years ago into 2s+24 to give us the father’s age.

2(24)+24 = 72

Father’s current age: 72
