Answer:
You are multiplying two factors in the argument. So we add the logs.
log(x4y3) + log((x2y5)1/3)
log(x4y3) + log(x2/3y5/3)
For each log term. The arguments are being multiplied. So we further add the logs. Also, any exponents become of the coefficients of logs.
4log(x) + 3log(y) + (2/3)log(x) + (5/3)log(y)
Combine like log terms.
(14/3)log(x) + (14/3)log(y)

How to find angles C and D.
Answer:
c = 21º
d = 100º
Step-by-step explanation:
In questions like this, always find the angles you can find and it will help you find more and more.
So let's start by finding angle e. We know that the sum of the angles in any triangle is equal to 180. So let's do 180 - (20 + 20) = 140
angle e = 140º
Now we don't know either C or D and are unable to find them with only e, so let's find other angles to help us. The 4 angles that aren't known at each corner of the square are easy to find, as we know for sure that they fully equal to 90º. So 90 - 20 = 70º. Both angles at the bottom corners = 70º. Now for the top corners: top left = 90 - 30 = 60º and top right = 90 - 40 = 50º.
As well as this, we can find a and b as well, but I think you already figured that out. angle a: 180 - (30 + 40) = 110º, angle b: 360 - (140 + 110) = 209º
Now we can figure out c and d, because we know that the sum of all angles in any quadrilateral is 360º. So the trapezium on the left, angle c: 360 - (70 + 60 + 209) = 21º. And finally right trapezium, angle d: 360 - (70 + 140 + 50) = 100º

A. Fill in the missing even or odd numbers.
- 16
1) 6, 8, 10,
2) 38, 42, 46,
58
3) 80, 74, 62, 56,
4) 61, 63, 65, _ 71
5) 109, 107, 105,99
1) 12, 14
This is the answer because each increasing number was increased by 2, so if you add 2 to 10, you'd get 12. If you add 2 to 12, you would get 14.
2) 50, 54
Same explanation as above but for the number 4.
3) 68, 50
Same explanation as 1, but with subtracting the number 6.
4) 67, 69
Same as number 1
5) 103, 101
Same as number 3 but subtracting the number 2
Hope this helps!!! :)

Three consecutive integers have a sum of 57. Find the integers.
Answer:
18, 19, and 20.
Step-by-step explanation:
Consecutive means beside. Numbers 2 and 3 are consecutive integers. Given this question, numbers 6, 8, and 9 could possibly be the answer. However, we don't know this, so let's represent the 6 as x, 7 as x+1. 9 is x+2. We know when these are added together the sum is 57, so 3x+3 should be 57. Now, solve as a normal algebraic question.

A local school board wants to determine the proportion of households in the district that would support starting the school year a week earlier. They ask a random sample of 100 households whether they would support starting the school year a week earlier, and 43 households responded that they would. The school board plans to construct a 95% confidence interval for the true proportion of households that would support starting the school year a week earlier. Are the conditions for inference met?
A)Yes, the conditions for inference are met.
B)No, the 10% condition is not met.
C)No, the randomness condition is not met.
D)No, the Large Counts Condition is not met.
The conditions for inference is not met in the question due to the fact that the large count condition is not met.
What is the large count condition in statistics?This is the condition in statistics that states that the numbers of the successes and the failures have to be greater than 10 for there to be a normal distribution.
Using this formula n(1-p) ≥ 10. The probabilioty is 95%, therefore it would be less than 10

First, find the least common denominator which is 15.
[tex](\frac{5}{5})\frac{2}{3} + (\frac{3}{3})\frac{1}{5}[/tex]
When we multiply by 5/5 or 3/3 we are not changing the value of the fraction, just turning the denominator into one which we can work with the other fraction's denominator.

(3-10i)(2+4i)
20 points
Answer:
46 -8i
Step-by-step explanation:
Multiplication of complex numbers is done in a fashion similar to multiplication of any binomials. The difference is that i² = -1, so some terms can be combined.
(3 -10i)(2 +4i) = 3(2 +4i) -10i(2 +4i)
= 6 +12i -20i -40i² = 6 -8i +40

Write an equation of the form y = mx for the line shown below. If appropriate, use the decimal form for the slope.
Answer:
y=3/4x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-(-3))/(4-(-4))
m=(3+3)/(4+4)
m=6/8
m=3/4
y-y1=m(x-x1)
y-(-3)=3/4(x-(-4))
y+3=3/4(x+4)
y=3/4x+12/4-3
y=3/4x+3-3

Answer: See below
Step-by-step explanation:
Let A represent an adult who visited a therapist
Let B represent an adult who used a non-prescription antidepressant
Given:
P(A) = 0.28 P
P (B) = 0.43
P(A Intersection B) = 0.22
a) P(B ∩ A) = P (B ∩ A) / P(A) = 0.22/0.27
P(B | A) = 0.79 or 79%
b) P(A ∩ B) = P (A ∩ B) / P(B) = 0.22/0.4.3
P(A | B) = 0.51 or 51%
Answer:
(a) 44.44%
(b) 71.43%
Step-by-step explanation:
Let A = adults who visited a therapist.
Let B = adults who used antidepressants.

Rong Huang can buy 4 books with 2/9 of his money. He can buy another 8 such books and 2 identical bags with the rest of his money. How many such bags can he buy with the original sum of money?
Step-by-step explanation:
remember, that a/a = 1, and this is always the "whole" in such fraction scenarios.
in our case here : 9/9 or 3/3.
4 books for 2/9 of his money.
8 books for then 2× 2/9 = 4/9 of his money.
that is together
12 books for 6/9 = 2/3 of his money.
that leaves 3/9 = 1/3 of his money for the 2 identical bags.
so, 1/3 of his money for 2 bags.
how many bags for the whole (3/3) money ?
1/3 × x = 3/3
x = 3
he could have bought 3×2 = 6 bags with the original sum of money.
