Answer:
log_(12(144))=2
Step-by-step explanation:
Answer:
[tex]log_{12}[/tex] 144 = 2
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
12² = 144 ← in index form
with b = 12, n = 2, x = 144, then
[tex]log_{12}[/tex] 144 = 2 ← in logarithmic form

Answer:
1. Unbiased sample.
2. Self-selected sample.
3. Stratified sample.
4. Systematic sample.
5. Convenience sample.
6. Biased sample.
Step-by-step explanation:
1. Unbiased sample: sample where every member of the population has an equal chance of being selected.
For example, a researcher randomly selecting a shopping mall and questioning the customers coming there.2. Self-selected sample: sample where members volunteer to take part.
For example, a researcher uploading a questionnaire online and then requesting for brainly members to take part.3. Stratified sample: members are selected from the different subgroups within a population.
For example, when a geographical region is stratified into subgroups by climate, habitat, soil type or elevation. A population grouped by males or females.4. Systematic sample: sample members are selected through the use of a rule.
For example, a researcher selecting the 10th house on a particular street.5. Convenience sample: sample where representatives are easily accessible.
For example, a researcher using a social media poll such as Twitter polls.6. Biased sample: sample not representative of the entire population.
For example, a researcher selecting only females when trying to determine the best cook in a class.Answer:
1. biased sample

Step-by-step explanation:
1. After running, Maggie is 3 miles east of her starting point, and 4 miles north of her starting point. What angle could represent her direction of travel?
Answer:
The angle is 53.13 degrees
Step-by-step explanation:
Here, we want to calculate angle representing the direction of travel
From the question, she is 3 miles east and 4 miles north of her starting point
So the angle that represents her direction of travel will be that which makes a cut with the horizontal (the east direction)
Now, let us picture a right-angled triangle, with 3 miles direction being the adjacent and the 4 miles direction (facing the angle we want to calculate and is the opposite)
the trigonometric identity to use is the Tangent
Tan theta = 4/3
theta = arc tan (4/3)
theta = 53.13 degrees
How many solutions does the system of equations below have?
y = 3x + 4
y + 6 = 3x
Answer:
0 / no solutions
Step-by-step explanation:
Rewrite both in terms to the form y = equation.
EQ1: y = 3x + 4 (already in correct form)
EQ2: y = 3x - 6 (subtracting 6 from both sides).
Now suppose there is an intersection, then:
3x + 4 = 3x - 6, subtracting 3x from both sides gives:
4 = -6, which is a contradiction!
Therefore there are 0 / no solutions

[tex]( \sin^{2} ( \frac{\pi}{ 4 } - \alpha ) ) = \frac{1}{2} (1 - \sin(2 \alpha ) )[/tex]
Prove
Step-by-step explanation:
[tex] \sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
Use the identity
[tex] \sin^2 \theta = \dfrac{1 - \cos 2\theta}{2} [/tex]
on the left side.
[tex] \dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
[tex] \dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
Now use the identity
[tex] \sin \theta = \cos(\frac{\pi}{2} - \theta) [/tex]
on the left side.
[tex] \dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
[tex] \frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]
Liz wants to buy a shirt for $25 how much will Liz’s shirt cost in a total if sales tax is 4%
26$
Step-by-step explanation:
1% = 4/100 * 25
1% = 1
25 + 1 = 26
Another way to solve
Percentage increase = 100% + 4%
104/100 = 1.04
1.04 * 25 =26
Solve there Systems of equations. 2x + y = 15

Answer:
your answer would be (4, 7)
Step-by-step explanation:
Part 1: Explain what the following variables represent and how changing each one affects the monthly payment amount: P, i, and t.
Part 2: Explain how changing each variable (P, i, and t) affects the total cost of principal and interest over the life of the loan.
Answer:
Part 1 and 2: P represents principle, or the original cost of the mortgage. i represents the annualinterest rate (r/n), and t represents time. When you change the time it affects monthlypayments because theres either more or less time to pay off the mortgage. Having a longertime to pay off means you'll have lower monthly payments. When the interest rateincreases, the monthly payment increases. This is because the higher the interest rate, themore interest you're paying. Changing the principle means you either have more or lessmoney to pay off.P2: Increasing i will increase the total cost since more interest will be charged. Increasingtime means there's more periods for interest to gather so the total cost will increase.Shortening the time will decrease the total cost because there will be less time for interestto accumulate.

Noya needs to determine the number of books that will fit into a box. If the box has a length of 18 inches and each book is StartFraction 2 Over 9 EndFraction of an inch thick, which expression can be used to determine the number of books that will fit into the box? 18 2/9 18 times 2/9 2/9 divided by 18 9/2 divided by 18
Answer:
A. 18÷2/9
Step-by-step explanation:
A. 18÷2/9
B. 18×2/9
C. 2/9÷18
D. 9/2÷18
Let
Total length of box = 18 inches
Thickness of each book = 2/9 inches
Number of books that will fit into the box = x
Number of books that will fit into the box = Total length of box ÷ Thickness of each book
x = 18 ÷ 2/9
= 18 × 9/2
= 162/2
= 81 books
The correct answer is A. 18÷2/9

Can I plz get the congruence and reason plz
Congruence is when there are 2 objects that have the same shape and size, or they "mirror" each other.
Question 6:
Congruence:
Yes, these two objects are congruent.
Reason:
They are congruent, because they have the same size and shape, or that they "mirror" each other.
Question 7:
Congruence:
Yes there is congruence, here. These two objects are similar shapes, but not completely congruent.
Reason:
These two objects have the same size, but not the exact same shape. If you look at point B you can see that the two angles are different, which means that they are similar shapes, but not completely congruent.
Hope this helps! :)

Multiply the two binomials 6x - 5 and 2x + 3 and write your answer in
simplified terms
Answer:
x = 2
Step-by-step explanation:
6x + -5 = 2x + 3
-5 + 6x = 2x + 3
-5 + 6x = 3 + 2x
-5 + 6x + -2x = 3 + 2x + -2x
-5 + 4x = 3 + 2x + -2x
-5 + 4x = 3 + 0
-5 + 4x = 3
-5 + 5 + 4x = 3 + 5
0 + 4x = 3 + 5
4x = 3 + 5
4x = 8
x = 2
here's the question for is you can't see.
what is the vertex of the equation below?
y=2(x-3)>2+4
1. (2,4)
2. (-3,4)
3. (-2,4)
4. (3,4)
From [tex]y=a(x-h)^2+k[/tex]
The vertex is at (h, k)
Therefore, from [tex]y=2(x-3)^2+4[/tex]
The vertex is at (3,4).
Thus, the answer is 4. (3,4)
Georgia needs to buy flea treatment for her dog. Pet Store 1 is offering the flea treatment for 40 percent off plus an additional 25 percent off their regular price of $33. Pet Store 2 is offering the same flea treatment for 55 percent off plus an additional 5 percent off their regular price of $34. Which location is offering the better price and how much cheaper is it? The flea treatment is $0.31 cheaper at Pet Store 2. The flea treatment is $1.05 cheaper at Pet Store 2. The flea treatment is $2.05 cheaper at Pet Store 1. The flea treatment is $2.36 cheaper at Pet Store 1.
Answer:
The flea treatment is $2.05 cheaper at Pet Store 1.
Step-by-step explanation:
Pet store 1
Regular price = $33
40% off the regular price
= 40% of $33
= 0.4 × 33
= $13.2
25% off the regular price
= 25% of $33
= 0.25 × 33
= $8.25
Total paid = $33 - $13.2 - $8.25
= $11.55
Pet store 2
Regular price = $34
55% off of the regular price
= 55% of $34
= 0.55 × 34
= $18.7
5% off of the regular price
= 5% of $34
= 0.05 × 34
= $1.7
Total paid = $34 - $18.7 - $1.7
= $13.6
Difference in price = $13.6 - $11.55
= $2.05
The flea treatment is $2.05 cheaper at Pet Store 1.

PLEASE HELP ME ASAP!!
Answer:
8. 5/6
9. 6.25, 6 and 1/4
10. 14.4
Step-by-step explanation:
Sorry that this is a little late. All of these problems end up with the same process to get to the answer. Since you want to find the rate, you would want to divide the amount of time taken by itself to find the unit rate. So basically, 8. would be 20 cm in 24 hours. You would divide both by 24 and you get 20/24 cm in 1 hour. and then you simplify the fraction and boom, there's your answer.

If you have a negative value for m what quadrants will the line be in?
Answer:
If the slope of a line is negative, the line WILL intersect quadrants II and IV. X and Y intersects of the line with negative slope have the same sign. Therefore if X and Y intersects are positive, the line intersects quadrant I; if negative, quadrant III.
