Answer: The required ratio is 1:1.
Step-by-step explanation:
Let the total number of CDs be 100
of CDs is given by
According to question,
of her Jazz CDs represents of all her CDs.
Let the number of Jazz CDs be x
So, it becomes
So, Number of Jazz's CDs is 50
Number of Jazz non CDs is given by
Ratio of her CDs to her non- CDs is given by
Hence, the required ratio is 1:1.
Let the first angle be x. Then the second angle can be represented by (90-x)+58. We then have
x = (90-x)+58. Simplifying, x = 90 - x + 58
Then 2x = 90+58, or 2x = 148, or x = 74 degrees.
The first angle is 74 deg. I am assuming that we find the complement of this 74 and then add 58 deg. Unfortunately, that results in 74 deg. Seems like we're going around in circles.
Please reread the original problem statement. To me, it's vague where it mentions "the measure of a complementary angle." I assumed that it really meant "the measure of the complement to "an angle," i. e., "the measure of the complement of 74 deg."
Could someone else shed light on this problem's wording and solution?
Answer:
Quadrant II
Step-by-step explanation:
Quadrant II
Answer:
4
Step-by-step explanation:
1. Find the Mean
(8+12+15+17+18)/5=14
2.For each number, subtract the Mean and square the result.
(8-14)^2=36
(12-14)^2=4
(15-14)^2=1
(17-14)^2=9
(18-14)^2=16
3. Find the Mean of those squared differences.
(36+4+1+9+16)/5=13.2
4.Take the square root of that and this is what you want.
square root of 12.7 = 3.6 (round up to 4)
30 is greater than 3. So 30 > 3
