Answer: Systematic sampling
Step-by-step explanation: Systematic sampling usually takes an ordered technique or process in dealing with samples. Systematic sampling could assume a randomized start point in selecting observations, However, every other successive points usually follow a fixed order or selection process. In the scenario above, the manager sampling choice involves an ordered and fixed selection process whereby every fifth sample after the initial point is considered. Hence, resulting in predictable points, such as 6th, 11th, 16th, 21st, 26th, 31st,...and so on.

Putting values of m and n in the equation
12/3 + 5(3)
4 + 15 = 19
(12)(3)/4
= 36/4 = 9
3(12) - 12(3)
36 - 36 = 0
Step-by-step explanation:
m= 12 and n = 3
[tex]a. \: \frac{m}{3} + 5n \\ \frac{12}{3} + 5 \times 3 = 4 + 15 = 19[/tex]
[tex]b. \frac{ mn}{4} = \frac{12 \times 3}{4} = \frac{36}{4} = 9[/tex]
c.[tex]3m - 12n \\ \\ 3 \times 12 - 12 \times 3 = 36 - 36 = 0[/tex]
Expand the logarithm fully using the properties of logs. Express the final answer in
terms of log .
log 6x^4
Answer:
P=log(2)+log(3)+4.log(x)
Step-by-step explanation:
To solve the problem, we need to recall the following properties of the logarithms:
[tex]log(x.y)=log(x)+log(y)[/tex]
[tex]log(x^y)=y.log(x)[/tex]
We have the expression:
[tex]P=log(6x^4)[/tex]
Factor 6=2*3:
[tex]P=log(2\cdot 3x^4)[/tex]
Apply the property of the product:
[tex]P=log(2)+log(3)+log(x^4)[/tex]
Now apply the property of the exponent:
P=log(2)+log(3)+4.log(x)
kostas gets a four year bank loan to buy a new car that is priced at 20,987. after four years Kostas Will have paid the bank it’s total of $22,960. what interest rate did the bank give him if the interest was compounded monthly. Show your work .
Answer:
r = 2.04%
Step-by-step explanation:
r = n{(A/P)^1/nt - 1}
Where,
r = interest rate = ?
n = number of periods = 12
A = future value = $22,960
P = present value = $20,960
t = time = 4 years
r = n{(A/P)^1/nt - 1}
r = 12{(22,960/20,987)^1/12*4 - 1}
= 12{(1.09)^1/48 - 1}
= 12{(1.09)^0.02 - 1}
= 12 (1.0017 - 1)
= 12(0.0017)
= 0.0204
r = 0.0204 × 100
= 2.04%
r = 2.04%

The average winter temperature at the South Pole is -49 degrees Celsius. The coldest temperature recorded in Antarctica was 40.6 degrees Celsius colder than the average winter temperature at the South Pole. What was the coldest recorded temperature in Antarctica?
Answer:
The coldest temperature at Antarctica is -89.6 degrees celsius
Step-by-step explanation:
Here, we are interested in calculating the coldest temperature in Antarctica.
In the question, we are simply told that the coldest Antarctica temperature was 40.6 colder than the average winter temperature at the south pole.
The average winter temperature at south pole = -49 degree celsius
The coldest temperature is thus -49-40.6 = -89.6 degrees celsius

Alex can run 5/4 miles in 1/12 hour. At this rate, how far can he run in 1 hour?
Answer:
15 miles in one hour
Step-by-step explanation:
Since we know that we need twelve 1/12 hours to make one full hour, we can multiply.
5/4 * 12
5/4 * 12/1
60/4
15
Best of Luck!
Answer: 15 miles
If he can already run 5/4 miles in 1/12 of an hour, we multiply.
First, let's simplify 5/4 to make it easier.
5/4 = 1 1/4.
Alex ran 1 1/4 miles in 1/12 of a hour.
Now, let's multiply 1 1/4 by 12.
1 1/4 x 12 = 15.
Answer = 15 miles. Hope this helps!
Daniel works in a market. He has a large bag of potatoes that weighs 261/4 pounds and he is going to sell them in smaller bags of 9/4 pounds each. If he uses up all the potatoes, how many smaller bags of potatoes will Daniel have filled?
Answer:
11 6/9
Step-by-step explanation:
Daniel works in a market
He has large bags of potatoes that weighs 26 1/4
Daniel is going to sell them in smaller bags 9/4 pounds each
Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows
= 26 1/4 ÷ 9/4
= 105/4 ÷ 9/4
= 105/4 × 4/9
= 105/9
= 11 6/9

Let's solve your equation step-by-step.
−5(x+1)+3x−3=−14
Step 1: Simplify both sides of the equation.
−5(x+1)+3x−3=−14
(−5)(x)+(−5)(1)+3x+−3=−14(Distribute)
−5x+−5+3x+−3=−14
(−5x+3x)+(−5+−3)=−14(Combine Like Terms)
−2x+−8=−14
−2x−8=−14
Step 2: Add 8 to both sides.
−2x−8+8=−14+8
−2x=−6
Step 3: Divide both sides by -2.
−2x
−2
=
−6
−2
x=3
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
-5(x + 1) + 3x - 3 = -14
Distribute within parenthesis
-5x -5 + 3x - 3 = -14
Combine like terms
-2x - 8 = -14
Add 8 to both sides
-2x = -6
Divide -2 by both sides
x = 3
I hope this helps :)
Which is a correct first step in solving the inequality –4(2x – 1) > 5 – 3x?
a. Distribute –4 to get –8x + 4 > 5 – 3x.
b. Distribute –4 to get –8x – 1 > 5 – 3x.
c. Subtract 2x from both sides of the inequality.
d. Add 1 to both sides of the inequality.
Answer:
B.)Distribute –4 to get –8x – 1 > 5 – 3x.
Step-by-step explanation:
Let U = {9, 10, 11, 12, 13, 14} and A = {11, 13}. Determine whether the statement A⊂U is true or false and find A'.
a. false; A' = {11, 12, 13, 14}
b. true; A' = {9, 10, 11, 12, 14}
c. false; A' = {9, 12, 14}
d. true; A' = {9, 10, 12, 14}
Answer:
D; A⊂U is true and A'={9, 10, 12, 14}
Step-by-step explanation:
A={11,13}
Because those numbers are included in the statement U={9,10,11,12,13,14}, we can say that it's true that A belongs to U.
A' is the numbers of U not including A. So, it would just be U without the 11 and 13, or {9,10,11,12}

3. A water balloon was thrown
from a window. The height
of the water balloon over
time can be modeled by the
function y= 16x2 + 160x + 50.
What was the maximum
height of the water balloon
after it was thrown?
Note: It the given equation the coefficient of [tex]x^2[/tex] must be -16 instead of 16.
Given:
Consider the height of the water balloon over time can be modeled by the function
[tex]y=-16x^2+160x+50[/tex]
To find:
The maximum height of the water balloon after it was thrown.
Solution:
We have,
[tex]y=-16x^2+160x+50[/tex]
Here, leading coefficient is negative. So, it is a downward parabola and vertex of a downward parabola, is the point of maxima.
If a parabola is [tex]f(x)=ax^2+bx+c[/tex], then
[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]
Here, [tex]a=-16,b=160,c=50[/tex]. So,
[tex]-\dfrac{b}{2a}=-\dfrac{160}{2(-16)}[/tex]
[tex]-\dfrac{b}{2a}=-\dfrac{160}{-32}[/tex]
[tex]-\dfrac{b}{2a}=5[/tex]
Now, put x=5 in the given equation.
[tex]y=-16(5)^2+160(5)+50[/tex]
[tex]y=-16(25)+800+50[/tex]
[tex]y=-400+850[/tex]
[tex]y=450[/tex]
The vertex of the given parabolic equation is (5,450).
Therefore, the maximum height of the balloon is 450 units after 5 units of time.
