A number, y, is equal to twice the sum of a smaller number and 3. The larger number is also equal to 5 more than 3 times the sma

Nata [24]

Answer:

The equations represent the situation is $y=2x+6$ and $y=5+3x$ .

Step-by-step explanation:

Consider the provided information.

First convert the statement into mathematical representation.

Consider the smaller number is x and the larger number is y.

y, is equal to twice the sum of a smaller number and 3.

This information can be written as: $y=2(x+3)$

Which can be further solve as:

$y=2x+6$

The larger number is also equal to 5 more than 3 times the smaller number.

This information can be written as: $y=5+3x$

Thus, the equations represent the situation is $y=2x+6$ and $y=5+3x$ .

Which can be further solve as:

$2x+6=5+3x$

$x=1$

Now, substitute the value of x in $y=5+3x$ .

$y=5+3$

$y=8$

Your height and weight are examples of which level of measurement? A. Ordinal B. Nominal C. Ratio D. Interval

Ivahew [28]

Answer:

C. Ratio

True for this case we have a clear definition of the 0 since the 0 for the heigth and the weigth represent absence of mass. And the differences between numerical values for the two variables are meaingful.

Step-by-step explanation:

We want to know which type of variable represent the weigth and the height. Let's analyze one by one the options given:

A. Ordinal

False since by definition an ordinal variable is "is a categorical variable for which the possible values are ordered". And for this case the height and the weigth are not categorical since represent quantitative data.

B. Nominal

False by definition and ordinal variable is which one that can't be represented by numeric values, and for this case the weight and the height are not example of this definition.

C. Ratio

True for this case we have a clear definition of the 0 since the 0 for the heigth and the weigth represent absence of mass. And the differences between numerical values for the two variables are meaingful.

D. Interval

False on this scale we don't have a clear definition of the 0. And for this case the heigth and the weight have a known definition of the 0 corresponding to the absence of mass. And since the ratios are meaingful for the heigth and the weigth then can't be an interval variable.

A triangle is placed in a semicircle with a radius of 3 yd, as shown below. Find the area of the shaded region.

Kitty [74]

Answer:

Considering that the shaded area is the part of the semi circle outside the triangle:

Area of circle= Pi x radius2 (this means radius squared)

Area of triangle= 1/2 x base x height

1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17

127.17 - (1/2 x 18 x 9) = 46.17cmsquared
