Answer:

The type of sample is Stratified sampling.

Step-by-step explanation:

Consider the provided information.

Types of sampling.

Random sampling is similar to placing the name of everyone in a hat and pulling out a few names.

In Systematic sampling, we list of elements is counted off.

Convenience sampling: data which is readily available is used. That is, the first people are running into by the surveyor.

In Cluster sampling, we divide the population into groups, usually geographically.

In Stratified sampling we divide population into groups called strata. but this time population might be separated into males and females.

Here the population is divided into groups of males and females therefore it is stratified sampling.

Hence, the type of sample is Stratified sampling.

Factor 7x3y4−7x2y5 completely.

Anastasy [175]

Answer:

Step-by-step explanation:

when we factor completely, we take a look at what is the biggest common factor of 7x³y⁴ and 7x²y⁵. In this case it is 7x²y⁴.

7x³y⁴-7x²y⁵ = 7x²y⁴(x-y) which is B.

timurjin [86]

The distance from the second destination back to Dallas is 918 miles

<h3>Given</h3>

A triangle has points Dallas, destination 1, and destination 2.

The distance from Dallas to destination 1 is 720 miles

The distance from destination 1 and destination 2 is 290 miles

the angle formed between Dallas, destination 1, and destination 2 is 125 degrees.

He moves from destination 1 to Dallas then destination 2

We could use cosine law to find the distance

<h3>What is cosine law?</h3>

The Law of cosines or cosine law means the relation between the length of sides of a triangle with respect to the cosine of its angle. It is also called the cosine rule

$b^{2}=a^2+c^2-2ac*cosB$

= $290^2+720^2-2*720*290*cos125$

=84100+518400-417600 cos 125

=602500-417600*(-0.5735)

=602500+239493.6

=841993.6

b=917.6 miles

≅918 miles

The distance is 918 miles he will fly from the second destination back to Dallas

How much sand would you need to fill this box ?

grin007 [14]

Step-by-step explanation:

We have,

l =5ft

b=2ft

h=3ft

$volume(v) = l \times b \times h$

v = (l*b*h)

v = (5*2*3)ft

v = (30)ft

.•. v = 30ft

6( 5-8x) +12= -54

UkoKoshka [18]

<span>6( 5-8x) +12= -54
30-48x+12=-54 this comes from distributing(multiplying) 6x5 and 6 times -8x
30+12-48x=-54 you have to add the coefficients 30+12
42-48x=-54
-42 -42
-----------------------
-48x=-96 divide by -48
x=2</span>
