Answer:
84.013 > 84.01
Step-by-step explanation:
84.013 is more than 84.01 because it has .12
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.
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

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
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

A child’s shoe box measures 4" by 6" by 3". What is the longest pencil you could fit into this box?
Answer:
5in
Step-by-step explanation:
Given data
Lenght= 4 in
Width= 6 in
Height= 3 in
Applying the Pythagoras theorem,
Let the longest pencil that could fit in be z
z^2= l^2+ h^2
z^2= 4^2+ 3^2
z^2= 16+9
z^2= 25
z= √25
z= 5 in
Hence the longest pencil is 5in

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.
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.

The last five houses built in town sold for the prices shown below. Find the mean price. Use pencil and paper. If a new house built in the town sold for $160,000, how would that affect the mean?
prices: $181,00; $187,00; $144,00; $176,00; $175,00
what is the mean price of the houses??
Answer:
172,600
Step-by-step explanation:
hii so basically the mean is the same as average so add all together and divide by how many prices in this case there originally were
so 181,000+187,000+144,000+176,000+175,000=863,000
then divide by 5
863,000/5=172,600

Which graph represents function g if g(x)=f(2x)
The new function g(x) which is equal to f(2x) will be stretched or compressed by the factor 2.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function f(x) shown in the coordinate plane.
The function g(x) = f(2x)
As we can see in the new function g(x) it is the transformation of the f(x).
Transformation is applied as below:
x → 2x (x is replaced by the twice of it)
= f(x)
= f(2x)
= g(x)
When the function is multiplied by a positive number it will be stretched or compressed according to that factor vertically and in the given function the factor is 2 which means the g(x) will be stretched or compressed according to that factor.
Thus, the new function g(x) which is equal to f(2x) will be stretched or compressed by the factor 2.

An antique chair was purchased in the year 2013 for $500. At the time of purchase, an appraiser estimated that
the value would increase by 10% every year. Which of the following functions can be used to model the
estimated dollar value of the chair years after purchase?
(A) f(t) = 500(0.1)
(B) f(t) = 500(0.9)
(C) f(t) = 500(1.1)
(D) f(t) = 500(10)
(E) f(t) = 510+
Answer:
A
Step-by-step explanation:
To find 10% of 500 you would multiply 500 by 0.1

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.
