Let θ be an angle such that cot θ= 12/5 and secθ<0.
Find the exact values of cosθ and cscθ.
Answers
9514 1404 393
Answer:
cos(θ) = -12/13
csc(θ) = -13/5
Step-by-step explanation:
The relation between the cot and csc is ...
cot² + 1 = csc²
The signs of the cot and sec tell you this is a 3rd quadrant angle, where cos and csc are both negative.
Then ...
csc(θ) = -√(1 +(12/5)²) = -√(169/25)
csc(θ) = -13/5
__
cos(θ) = cot(θ)/csc(θ) = (12/5)/(-13/5)
cos(θ) = -12/13

200 shares of a stock were bought for $58 per share the broker's
commission was $40 plus $0.25 / share. The stock was later sold for $66/
share the broker's commission was $50 plus $0.32/ share. Calculate the
profit from the sale
$1596
$1000
$1396
$1624
Answers
Answer:
1396
Step-by-step explanation:
Profit= revenue-cost
Let's start off by calculating the revenue (the amount they get when they sold the stock) 200*66=13200
Now we need to calculate the cost
40+50+200(.32+.25+58)=11804
13200-11804=1396
Answer:C is correct
Step-by-step explanation:
200*58= 11600
Commission = 40+ (200*0.25)
Commission = 90
Total = 11690
Sell
200*66= 13200
Commission 50+ (0.32*200)
Commission = 114
Sell for 13200-114 = 13086
Profit = 13086 - 11690
Profit = 1396

Answer:
$3400
Step-by-step explanation:
The way these tax tables are structured, you pay 3% on the first $10,000, 5% on the next $40,000, and 5.5% on the remaining $20,000 above $50,000.
tax = 0.03·10,000 +0.05·(50,000 -10,000) +0.055·(70,000 -50000)
= 300 + 2000 +1100
= 3400 . . . dollars
The tax owed on $70,000 is $3,400.
_____
Additional comment
I like to rewrite this sort of table to a different format:
3% of income . . . . . . . . . . . . . . . applies for income ≤ 10,000(5% of income) -$200 . . . . . . . . applies for 10,000 < income ≤ 50,000(5.5% of income) -$450 . . . . . . .applies for 50,000 < income ≤ 100,000For an income of $70,000, the tax computation using this form is one multiplication and one addition, rather than 3 multiplications and 4 additions as used when navigating the given table.

Which confidence level would produce the widest interval when estimating
the mean of a population from the mean and standard deviation of a sample
of that population?
A. 38%
B. 26%
C. 54%
D. 61%
Answers
61% confidence level would produce the widest interval since it is the highest.
Confidence intervalZ score is used to determine by how many standard deviation the raw score is above or below the mean.
Confidence interval is given by: mean ± margin of error
The margin of error is given by: [tex]z_\frac{\alpha }{2}* \frac{standard\ deviation}{\sqrt{sample\ size} }[/tex]
The confidence interval is dependent on the margin of error which also depends on the z score of the confidence level, hence the interval increases as the confidence level increases.
61% confidence level would produce the widest interval since it is the highest.

Mai and Elena are shopping for back-to-school clothes. They found a skirt that originally cost $30 on a 15% off sale rack. Today, the store is offering an additional 15% off.
To find the new price of the skirt, in dollars, Mai says they need to calculate 30. 0.85 0.85. Elena says they can just multiply 30.0.70.
1. How much will the skirt cost using Mai's method?
2. How much will the skirt cost using Elena's method?
3. Explain why the expressions used by Mai and Elena give different prices for the skirt.
Answers
Answer:
Mai
Step-by-step explanation:
1. 21.675 R $22
2. $21
Mai is the correct method because 15%-100%=85, which shows the percentage that is left to multiple. Then she multiples 0.85 times 2 as she was able to take off 15% twice. Elena's is incorrect because she added the two 15% off and subtracted that by 100 giving her 70. Which is the incorrect decimal to multiple by. Hope this helps.

Assume that blood pressure readings are normally distributed with a mean of 117 and a standard deviation of 9.6. If 144 people are randomly selected, find the probability that their mean blood pressure will be less than 119.
Answers
Answer:
0.9938
Step-by-step explanation:
Let mean blood pressure be = x
Pr ( x < 119 ) can be found using ' z value ' = ( x - u ) ÷ ( s / √n ) ; where x = 119 , u = mean = 117 , n = no. of sample items = 144 , s = standard deviation = 9.6
z = (119 - 117) ÷ (9.6 / 144) = -2 ÷ (9.6 / 12) = -2 / 0.8 → z = 2.5
Pr (x < 119) = P (z < 2.5)
P = 0.9938
