The population is all of her friends and the sample is the best friend about whom she is performing this study. The population is the best friend about whom she is performing this study and the sample is all of her friends. The population is the 50 text messages she randomly selected and the sample is all text messages she sent. The population is all text messages she sent and the sample is the 50 text messages she randomly selected.
The statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.
What is simple random sampling?Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.
We have:
A student would like to know what proportion of the text messages she sends is to her best friend.
The number of sample methods she selects = 50 text messages
As the sample consists of the 50 texts she randomly chose from the population of all the texts she sent.
Thus, the statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.

You bought shoes for $39 that were marked 20%
off. You have to pay
9% tax. What is the total for
the shoes?
Answer: $34
Step-by-step explanation:
39 x 0.2 = 7.80, the discount
39 - 7.80 = 31.20
31.20 x 0.09 = 2.80, the tax
31.20 + 2.80 = 34
Total cost for the shoes: $34
Answer:
24.99 dollars
Step-by-step explanation:

parallel lines p and q are cut by two non parallel lines m and n as shown in the figure the value of x is ? degrees and the value of y is ? degrees
Answer:
Step-by-step explanation:
x+102+115+(180-115)=360
x+282=360
x=78 degrees
y=115 degrees
Answer:
x = 78
y= 115
Step-by-step explanation:
On the angle where p and m meet, we have congruent angles that both equal 102 degrees. The adjacent angles will add up to 180 degrees on a line. So, to find the missing angle, do this:
180-102 = 78 degrees
x is equal to the top right angle where p meets m as they are congruent.
x = 78
You can find y by realizing that the given angle on q meets n are congruent angles. If this angle equals 115 degrees, then y must also equal 115 degrees.

You walk 1/4 miles to a shoe store. Then you walk another 2/5 miles to a music store. How many miles ha r you walked in all?
Answer and Step-by-step explanation:
[tex]\frac{13}{20}[/tex], or 0.65 miles.
Convert both to common denominator, then add together.
They have a common denominator of 20.
[tex]\frac{1}{4}[/tex] × [tex]\frac{5}{5} = \frac{5}{20}[/tex]
[tex]\frac{2}{5}[/tex] × [tex]\frac{4}{4} = \frac{8}{20}[/tex]
[tex]\frac{5}{20} + \frac{8}{20} = \frac{13}{20}[/tex]
Answer:
I would walk [tex]\frac{13}{20}[/tex] or 0.65 miles.
Step-by-step explanation:
[tex]\frac{1}{4}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{5}{20}[/tex] + [tex]\frac{8}{20}[/tex] = [tex]\frac{13}{20}[/tex] or 0.65

Enter
Answer:
Angle x is 38.
Step-by-step explanation:
If its congruent it means it is equal. Vertical angles are equal to each other.
The measure of x is 38°.
What are corresponding angles?The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.
Corresponding angles are equal.
We have,
Vertical angles are congruent.
x° and 38° are vertical angles.
Now,
x° = 38°
Thus,
The value of x is 38°.

Bryan and Serena had the same amount of money initially. After Bryan donated $258 and Serena donated $234 to charity, Serena had 4 times as much as Bryan. How much had Serena in the end?
Answer:
Serena had $32 at the end.
Step-by-step explanation:
They both had x in the beginning.
Bryan donated $258, so now he has
x - 258
Serena donated $234, so now she has
x - 234
Serena now has 4 times as much money as Bryan.
x - 234 = 4(x - 258)
x - 234 = 4x - 1032
-3x = -798
x = 266
They both had $266.
$266 - $234 = $32
Answer: Serena had $32 at the end.
