The answer is 5. If you do 3/8 x 4 you get 1.5, if you multiply 1/2 x 3 you get 1.5, if you do 1/4 x 3 you get .75 and if you do 5/8 x 2 you get 1.25. So, 1.5 + 1.5 + .75 + 1.25 = 5
Answer:
2/3 of band practice was spent playing music.
Step-by-step explanation:
First find the common denominator.
6 times 4 is 24
8 times 3 is 24
multiply the numerators by the same value as the denominator (for 1/8 both the 1 and the 8 would be multiplied by 3, and for 1/6 both the 1 and the six would be multiplied by 4)
4/24 + 3/24
next the questions is asking for the remaining practice time.
add numerators when the denominators are the same.
4 + 3 = 7
= 7/24
24/24 - 7/24 = 16/24
(24 - 7 = 16)
now divide both the numerator and denominator by the same number.
16 ÷ 8 = 2
24 ÷ 8 = 3
The answer would be that 2/3 of band practice was spent playing music.
So we want to find the radius of the circle. So just divide 56.52 by 3.14 and 2, which is 9. And then to find the area, just square 9 and multiply it by pi, which is 354.34 square inches.
The area of the rug is 354.34 square inches.
Answer:
<h2>False.</h2>
Step-by-step explanation:
A inscribe circle in a triangle means to draw the biggest circle possible inside such triangle. To do that perfectly, we first have to find the incenter of the circle, which is the intersection of all three internal bisector of the triangle, that point is the center of the inscribed circle.
Therefore, the statement is false.
In addition, a circumcenter allow to perfectly draw a circumscribed circle, which is outside the triangle, which is not the case here.
An image showing the inscribed circle is attached.
Answer:
An independent sample.
Step-by-step explanation:
In this scenario, to compare the production techniques used by foreign and local firms in Brazil, a random sample of 80 foreign firms and a random sample of 80 local firms are selected. We can safely conclude that this study uses an independent sample design.
An independent sample design can be defined as a research method that usually involves the use of multiple experimental groups (two or more). The samples or participants are only in one group and as such each group has no relationship with the other. This simply means that, the samples in a particular group is having no relationship with the other samples in another group.
Ultimately this implies, each samples are independent and satisfies only one condition of the independent sample design during the experiment to compare the production technique used by foreign and local firms in Brazil.
<em>Hence, the researcher would use only two variables or conditions: a random sample of 80 foreign firms and a random sample of 80 local firms are selected.</em>
