A semiconductor manufacturer produces devices used as central processing units in personal computers. The speed of the devices (in megahertz) is important because it determines the price that the manufacturer can charge for the devices. A boxplot for the speeds of 116 randomly selected devices is given below. Using only the boxplot, what is the approximate interquartile range of speeds
Answer:
[tex]IQR = 38[/tex]
Step-by-step explanation:
Given
See attachment for box plot
Required
The interquartile range (IQR)
This is calculated using:
[tex]IQR = Q_3 - Q_1[/tex]
On the second attachment, I identify the positions of Q1 and Q3 respectively;
[tex]Q_1= 662[/tex]
[tex]Q_3 = 700[/tex]
So:
[tex]IQR = 700 - 662[/tex]
[tex]IQR = 38[/tex]
The interquartile range is 38

10 You are planning a party for a group of friends. The cost of
the party will be $30 to rent the room plus $5 per person.
You have a budget of $75. Which inequality gives you the
best estimate of the number of people p that you can invite
to your party?
Answer:
30+5p ≤ 75 (C)
Step-by-step explanation:
Well ”p” is amount of people and every person costs 5 dollars do 5p. 30 dollars for a single room so that s a one time fee, 30+5p
Now the budget can’t be greater than 75 and 75 is the greatest number so we use a less then or equal to sign
5p+30≤75 or (C)

C.
(x − 3)3(x6 + 3x3 + 9)
D.
(x + 3)3(x6 − 3x3 + 9)
The factored form of the expression is [tex]x^9+27=(x^3 + 3) (x^6 - 3x^3 + 9 )[/tex]
Sum of squares of variablesThe sum of squares of variable a and b is expressed as:
[tex]a^3+b^3=(a + b) (a^2 - ab + b^2 )[/tex]
Given the expression x^9 + 27, this can be written as;

Rate per hour Rs.1.50 per hour Time allowed for job = 20 hours Time taken = 15 hours Calculate the total earnings of the worker. . under the Halsey Plan.
Answer:
Rs. 22.5
Step-by-step explanation:
Given that Rate per hour is Rs.1.50, then;
1hour = Rs. 1.50
If time taken to work is 15hrs, then;
15hrs = x
Divide both expressions
1/15 = 1.50/x
Cross multiply
1 * x = 1.50 * 15
x = 22.5
Hence the total earning of the worker is Rs. 22.5

Mr x will retire at the age of 60 years he wishes to have an amount of 200000 in his account at the time of retirement currently he is 40years and has an amount of 25000 how much interest rate bank should offer
Answer:
Rate of interest = 10.95%
Step-by-step explanation:
Given:
Amount deposit in bank = 25,000
Number of year = 60 year - 40 year = 20 year
Future value = 200,000
Find:
Rate of interest
Computation:
A = P[1+r]ⁿ
Future value = Amount deposit in bank[1+Rate of interest]ⁿ
200,000 = 25,000[1+r]²⁰
8 = [1+r]²⁰
1.1095 = 1 + Rate of interest
Rate of interest = 0.1095
Rate of interest = 10.95%

i dont know how to solve this questions without a graphing on a calculator but i can't use calculator for this question pls help
Answer:
D
Step-by-step explanation:
When the denominator is equal to 0, the function doesn't exist. So factor the bottom, luckily its already partially factored.
(x^2 + 8x + 12) = (x+2)(x+6)
So now the denominator is (x+2)(x+6)(x-3)
The function doesn't exist when x = -2, -6, 3
Now we know there are 3 total discontinuities.
A and B can be eliminated
Since there is an (x+2) on the top and the bottom, they don't affect the shape of the function, but only causes a removable discontinuity when x = -2.
However, (x+6) and (x-3) are only on the bottom, so they DO change the shape, so they are non-removable
The answer therefore is 1 removable and 2 non-removable; D
Answer:
We have 1 removable discontinuity and 2 non-removable discontinuities
Step-by-step explanation:
Note that
[tex]x^2+8x+12 = (x+2)(x+6)[/tex]
Initially, we have discontinuities at
[tex]x = -2; x = -6; x = 3[/tex]
Considering
[tex]f(x)=\dfrac{(x+2)(x-6)}{(x^2+8x+12)(x-3)}[/tex]
But
[tex]\dfrac{(x+2)(x-6)}{(x^2+8x+12)(x-3)}= \dfrac{(x+2)(x-6)}{ (x+2)(x+6)(x-3)}= \dfrac{(x-6)}{ (x+6)(x-3)}[/tex]
We have now two discontinuities at
[tex]x = -6; x = 3[/tex]
