698.52 Euro
Step-by-step explanation:
A sample of 300 subscribers to a particular magazine is selected from a population frame of 9,000 subscribers. If, upon examining the data, it is determined that no subscriber had been selected in the sample more than once:________.
A. the sample could not have been random
B. the sample may have been selected without replacement or with replacement
C. the sample had to have been selected without replacement
D. the sample had to have been selected with replacement
Answer:
C
Step-by-step explanation:
It is determined that no subscriber had been selected in the sample more than once the sample had to have been selected without replacement.
What is the sample?A sample is a subset of data drawn from a larger population by a researcher using a predetermined selection process. These components are referred to as sample points, sampling units, or observations.
If it is determined that no subscriber had been selected in the sample more than once, this means that each subscriber was only included once in the sample. This can only occur if the sample was selected without replacement, meaning that each subscriber was selected once and only once from the population frame.
Therefore, the correct answer is C. the sample had to have been selected without replacement.

Answer:
335 mm²
Step-by-step explanation:
This will be so easy, that you can do it in the future by yourself!
Okay let's start by splitting this figure, the easiest way seems to be by cutting off that little part, you know what just let me show a picture.
Okay you shuold be able to see the picture, so the small square has an area of 20, since 5 times 4 is 20 mm! The larger square has an area of 315!
How did I find this? Take that small 10mm in the side and add it to 5mm, that would be 15. 15 times the bottom the width, it would be 15 * 21. 15 times 21 is equal to 315.
Now, we add both those areas together, to get ourselves a nice little 335 mm²
I hope that helped, have a great day!!

MODELING REAL LIFE A survey asked students to choose their favorite social media website Social Media Website Number of Students Website A 35 Website B 13 Website C 22 Website D 10 a. What fraction of the students chose Website A?
__ chose Website A.
b. What percent of the students chose Website C?
__ % chose Website
Answer: For A = 35/80 or 43.75% C = 22/80 or 27.5 %
Step-by-step explanation:
I’m not sure if this is right but since 35 students choose A that would be the numerator and the denominator is how many people voted and when you add all 4 options you get 80 so it would be 35/80 and same apply to C which would be 22/80

What is angle M and N and the length of NP
Best answer gets brainliest!!!!
Answer:
3
Step-by-step explanation:
Answer:
Angle M and N is 45 degrees, and the length of NP is approximately 6 cm
Step-by-step explanation:
With angle P being 90 degrees. The angles of M and N, must add up to 90 degrees as well.
*triangles add up to a total of a 180 degrees, (180 - 90 = 90)
9 ÷ 2 = 45
So: ∠M = 45° and ∠N = 45°
To find the length of NP, use the pythagorean theorem.
a² + b² = c²
a = MP = 5
b = NP = x
c = MN = 7.8
(5)² = 25
(7.8)² = 60.48
25 + x² = 60.48
x² = 60.48 - 25
x² = 35.84
x = √35.84
x = 5.986 = 5.99
NP = 5.99 = 6
96g + 80f and explain
Answer:
16(6g + 5f)
Step-by-step explanation:
To factor 96g + 80f, we must find the GCF of 96 and 80. We don't factor g and f since they're totally different and can't be factored.The GCF of 96 and 80 is 16.To factor the equation:
96g + 80f
16(6g + 5f)

What is the area of the quadrilateral and what is the perimeter
Answer:
Area of Trapezoid = (b1 + b2)h
2
Area = (9 in + 17 in) (3 in = 1/4 ft)
2
A = (26 in)(3 in)/2
A = 78 in2/2
A = 39 in2
Perimeter = bi + b2 + 2l
P = 9in + 17 in + 2(5 in)
P = 26 in + 10 in
P = 36 inches

Indiana now has 8 different area codes. How many different phone numbers are available within Indiana if the numbers can repeat? Remember that phone numbers have an area code followed by 7 digits.
Answer:
Well, this could turn out to be a simple permutation problem: you have ten number choices (0-9) for each digit of a phone number and repetitions are allowed. Technically, there could be as many as \begin{align*}10^{10} = 10,000,000,000\end{align*}, or 10 billion possible phone numbers.

Cassie rolls a fair number cube with 6 faces labeled 1-6. She rolls the number cube 300 times. Which result is most likely?
a.Cassie will roll a 1 or 2 about 50 times.
b.Cassie will roll an even number exactly 150 times.
c.Cassie will roll a 1 or 2 exactly 50 times.
d.Cassie will roll an even number about 150 times
Answer: B
Step-by-step explanation:
Process of elimination:
A: 1 or 2 is 2 favorable outcomes
2/6 or 1/3
one third of 300 is 100, not 50
B: 2, 4, and 6 are even numbers (3 favorable outcomes)
3/6 or 1/2
1/2 of 300 is 150
I say the answer is B. Sorry if I’m wrong.

Anastasia hits her golf ball off the tee. The height of the golf ball is modeled by the function f(x) =-5x^2+25x+1, where x is the number of seconds after the golf ball is hit. How long is the golf ball in the air?
9514 1404 393
Answer:
5.04 seconds
Step-by-step explanation:
Assuming the ball is in the air until f(x) = 0, we want to find x such that ...
0 = -5x² +25x +1
0 = x² -5x -1/5 . . . . . divide by -5
1/5 = x² -5x . . . . . . . add 1/5
1/5 +25/4 = (x² -5x +25/4) . . . . complete the square
129/20 = (x -5/2)² . . . . . . . . . . write as a square
x = 5/2 +√(129/20) ≈ 5.039685 . . . . square root, add 5/2
The ball stays in the air about 5.04 seconds.

Measurements were taken from snails of the shell weights and the widths of the opercula. Plot a graph of opercula width (y-axis) versus shell weight (x-axis). Estimate the correlation coefficient and test to see if there is a significant association shell weights and the widths of the opercula. Use a 5% level of significance.
Opercula width
Shell weight (g) (mm)
12 10.1
10 9.0
7 5.5
14 9.9
11 8.3
8 8.5
10 8.0
9 6.4
6 6.2
13 8.1 2.306
Answer:
Yes,there is a significant association shell weight and the widths of the opercula
Step-by-step explanation:
Using a correlation Coefficient calculator :
Given the data above :
The Coefficient of correlation(r) obtained is :
0.7632
Obtaining the test statistic :
T = r² / √(1 - r²) / (n - 2)
T = 0.7632² / √(1 - 0.7632²) / (10 - 2)
T = 0.58247424 / 0.2284528
Test statistic = 2.550
The Pvalue from r score , N = 10
Pvalue(0.7632, 10) = 0.01022
α = 0.05
If Pvalue < α ; reject H0
Pvalue < α ; We conclude that there is a significant association shell weights and the widths of the opercula
Lexi is fishing from a small boat. A fish swimming at the same depth as the hook at the end of her fishing line is 16 feet away from the hook. If Lexi is 20 feet away from the fish, how far below Lexi is the hook?

Step-by-step explanation:
One Pythagorean Triple is 3, 4, 5. 32 + 42 = 52
Any multiple of the three numbers is also a Pythagorean Triple:
(3 · 3)2 + (3 · 4)2 = (3 · 5)2
92 + 122 = 152
How long will it take your money to double if you put $500 into an account compounded quarterly at 2.9%?
=======================================================
Work Shown:
A = P*(1+r/n)^(n*t)
1000 = 500*(1+0.029/4)^(4*t)
1000 = 500*(1.00725)^(4*t)
1000/500 = (1.00725)^(4*t)
2 = (1.00725)^(4*t)
log(2) = log( 1.00725^(4*t) )
log(2) = 4*t*log( 1.00725 )
4*t*log( 1.00725 ) = log(2)
t = log(2)/( 4*log( 1.00725 ) )
t = 23.9881659971072 The value is approximate
t = 24 when rounding to the nearest full year
It takes approximately 24 years to double your money.
