A student would like to know what proportion of the text messages she sends are to her best friend. She selects a random sample of 50 text messages she sent and determines the proportion of those messages that are sent to her best friend. Which of the following statements is true? 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.

How is depositing money into the bank similar to giving the bank a loan
Solve number 4 please
Answer:
3
Step-by-step explanation:
Slope is given by
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
where y2 = -1, y1 = -7, x2 = -1, x2 = -3
[tex] \frac{ - 1 - ( - 7)}{ - 1 - ( - 3)} = \frac{ - 1 + 7}{ - 1 + 3} [/tex]
[tex] = \frac{6}{2} = 3[/tex]
This drawing shows an Isosceles triangle. Work out the size of angle a.
For the given triangle the measurement of the angle 'a' is 50 degrees.
Use the definition of isosceles triangle defined as:
A triangle with two equal-length sides is said to be isosceles. An isosceles triangle has equal angles on either side of its equal sides.
In the given triangle:
Two sides are of equal length
One angle is 65 degrees and the other is of 'a' degree.
Since we know that,
For an isosceles triangle,
Two sides and two angles of the opposite side are equal.
Therefore,
The third angle of the triangle is also 65 degrees.
Since we know that,
The sum of the interior angles of a triangle = 180 degrees.
Therefore,
a + 65 + 65 = 180
a = 180 - 130
a = 50 degree
Hence,
The measure of an angle is 50 degrees.

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.
Your school is printing programs for the honor society induction ceremony. L & L Printing will print the programs for $350 plus an additional $1.50 per program. Red Baron will print the programs for $1.82 per program. They do not have an initial fee.
Identify the slope for each of the Printing Companies
Answer:
The slope for L & L Printing is of $1.50, while for Red Baron is of $1.82.
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope, which represents how much y changes when x changes by 1 unit.
In this question:
The slope for each of the printing companies is the price of a program. Then:
The slope for L & L Printing is of $1.50, while for Red Baron is of $1.82.
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.
ms. Jackson's class is on a field trip to the museum of nature history.the cost for admission is$7per adult and$5per child
Point B is a point of tangency. Find the radius r of ⊙C.
Since Point B is a point of tangency, there is a right angle being created on the edge of that circle.
This means that the Pythagorean Theorem can be applied to solve for r.
[tex]a^2+b^2=c^2[/tex]
[tex]r^2+24^2=(16+r)^2[/tex]
*A common mistake here is distributing the square to both 16 and r, whereas you should be multiplying 16+r by itself (FOIL).*
[tex]r^2+576=r^2+32r+256[/tex]
The [tex]r^2[/tex]s cancel.
[tex]32r+256=576[/tex]
[tex]32r=320[/tex]
[tex]r=10[/tex]
The radius r of Circle C is 10.

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:

Answer:
Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
Since both x axis are the same number, you have a "special case" line here.Your line is perfectly vertical, and has an infinite (or undefined) slope. It is this way because in the fraction above, it is impossible to divide by zero to find m! In this case, the equation of your line doesn't even use y=mx+b. Instead, the equation of the line is x=3

If a car has tires with a radius of 1.5 ft and the tires are spinning at 840 rpm (revolutions per
minute), how fast is the car traveling in mph?
[There are 5280 feet in 1 mile) Round your final answer to 2 decimal places.
Answer:
89·98 mph
Step-by-step explanation:
First, we get the circumference of the tires:
Circumference = [tex]\pi[/tex] × (radius × 2)
Circumference = 3.142 × (1·5 × 2)
Circumference = 3·142 × 3
Circumference = 9·426 ft
The circumference of the tire is equal to one round.
1 round = 9·426 ft
840 rounds = ?
We cross multiply to get the length that the tires would cover in a minute
= 840 × 9·426
1
1 minute = 7917·84 ft
60 minutes = ?
60 × 7917·84
1
= 475070·4 ft
5280 feet = 1 mile
475070·4 feet = ?
475070·4 × 1
5280
475070·4 ÷ 5280 = speed of the car in mph
89·97545
Round this off to 2 decimal places...
= 89·98 mph

At the beginning of the Occupation, the Nazis basically let the Jews go about their business. This all changes in October 1940. Measures are introduced one after the other. Civil servants must sign an official declaration stating whether they are Jewish or not. Just like in Germany earlier on, Jewish civil servants and teachers are fired from their jobs. At the beginning of 1941, all Jews in the Netherlands must register.
