you first need to change the mixed number to an improper fraction

$\frac{13}{8}-\frac{3}{4}$

then multiply the second fraction by 2 so that the denominator is the same in both fractions

$\frac{13}{8} -\frac{6}{8}$

$\frac{7}{8}$

Find the area of the shaded region

SOVA2 [1]

We know that, Area of a Circle is given by : πR²

Where : R is the Radius of the Circle.

We can Notice that : The Given Figure is One - Fourth of the Circle with Radius 'R'

$\mathsf{\implies Area\;of\;One\;Quarter\;of\;the\;Circle = \frac{\pi R^2}{4}}$

We can Notice that : The Quarter of the Circle is divided into 3 Equal Parts and The Shaded Region is One of the Equal Part.

$\mathsf{\implies Area\;of\;Shaded\;Region = \frac{\frac{\pi R^2}{4}}{3}}$

$\mathsf{\implies Area\;of\;Shaded\;Region = {\frac{\pi R^2}{12}}}$

In scoop county 16.8% of residents have diabetes. If 12,914 scioto county residents have diabetes, what is the population of the

Sergeu [11.5K]

The population of the county is 76,869.

Step-by-step explanation:

Given,

Number of people with Diabetes = 12914

Percent of people with Diabetes = 16.8%

Let,

x be the number of people in county.

16.8% of x = 12914

$\frac{16.8}{100}x=12914\\0.168x=12914$

Dividing both sides by 0.168

$\frac{0.168x}{0.168}=\frac{12914}{0.168}\\x=76869.04$

Rounding off to nearest whole number

x = 76,869

The population of the county is 76,869.

to test a hypothesis about a given variable, experimental and control groups are tested in parallel. which of the following best

NeX [460]

The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."

<h3>What is experimental design?</h3>

The process of deciding which variables to use in an experiment to test a particular hypothesis is called experimental design.
To properly collect data and evaluate the hypothesis, the experimental design method is used.

Now,

A specified variable is changed in the experimental group in a well-known fashion.
That selected variable is left unaltered in the control group so that comparisons can be conducted.
Control variables are variables that are utilized in an experiment to serve as a baseline against which the data from the experimental variables are gathered and evaluated (which is why the other answers are incorrect).
In the experimental group, it is advisable to modify just one variable at a time so that any differences from the control group may be quickly linked to the one variable that was altered.

Hence, amongst all the given options, The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."
