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>

Write an equation for the situation.
ella [17]
Let a be the variable for the equation.

now equation for the situation is 1a + 2(a-3) = 91.50
1a + 2a - 6 = 91.50
3a = 97.50

thus, a = 97.5/3 = 32.5$

Now, price of first blouse = 32.5
The price of other two blouse = 32.5-3 = 29.5$

Find the distance between the points given.<br><br> (-10, 3) and (-10, 12)<br><br><br> 9<br><br> 15
Novosadov [1.4K]
The distance between the points (x₁,y₁) and (x₂,y₂):
d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

(-10,3) \\&#10;x_1=-10 \\ y_1=3 \\ \\ (-10,12) \\ x_2=-10 \\ y_2=12 \\ \\&#10;d=\sqrt{(-10+10)^2+(12-3)^2}=\sqrt{0+9^2}=\sqrt{9^2}=9

Another method:
The points have the same x-coordinate so they lie on the same line. y-coordinates are positive so you just subtract 3 from 12. See the picture in the attachment.

The answer is 9.

Sines/ Cosines topic. In the triangle below round to the nearest tenth. Include explanation if possinle
vredina [299]

By the law of sines,

\dfrac{\sin90^\circ}{17}=\dfrac{\sin y^\circ}9

\implies\sin y^\circ=\dfrac9{17}

(since \sin90^\circ=1)

\implies y=\sin^{-1}\left(\dfrac9{17}\right)\approx32.0

How many different ways can 3 singers be selected from 5 who came to an audition
abruzzese [7]

This is known as "5 take 3", where ordering is not important.

\binom{5}{3} = \frac{5!}{3!(5-3)!} = \frac{120}{6\cdot2} = 10
