I thought of a two-digit number. The unit digit of my number is 7 more than the tens digit cubed. What is my number?
Answer:
18.
Step-by-step explanation:
If the tens digit is x^3 the unit digit is x^3 + 7
So 10 * x^3 + x^3 + 7 < 100 (as its a 2 digit number).
11x^3 < 93
x^3 < 8 5/11
x < 2.04
As x must be an integer it is either 1 or 2.
It cannot be 2 as 2^3 = 8 and 8+7 = 15 which cannot be the tens digit so it must be 1.
The answer is 1 and (1+7) = 18.
Answer:
18.
Step-by-step explanation:
If the tens digit is x^3 the unit digit is x^3 + 7
So 10 * x^3 + x^3 + 7 < 100 (as its a 2 digit number).
11x^3 < 93
x^3 < 8 5/11
x < 2.04
As x must be an integer it is either 1 or 2.
It cannot be 2 as 2^3 = 8 and 8+7 = 15 which cannot be the tens digit so it must be 1.
The answer is 1 and (1+7) = 18.

Suppose that a tea company estimates that its monthly cost is C(c) = 500x² + 100x and its monthly revenue is R(2) = -0.6x3 + 700x2 – 400x + 300, where x is in thousands of boxes of tea sold. The profit is the difference between the revenue and the cost. What is the profit function, p(X)?
O A. P(x) = 0.6x3- 200x2 + 500x+ - 300
OB. P(x) = -0.6x3 + 1200x2 – 300x + 300
O C. P(x) = -0.6x3 + 200x2 – 500x + 300
D. P(xl = 0.6x3 + 200x2 – 500x + 300
Answer:
p(x) = 0.6x³ - 200x² + 500x- 300
Step-by-step explanation:
Given the cost function and revenue function as:
C(x) = 500x² + 100x
R(x) = -0.6x³ + 700x² – 400x + 300
To get the profit function:
p(x) = C(x) - R(x)
p(x) = 500x² + 100x -(-0.6x³ + 700x² – 400x + 300)
open the parenthesis
p(x) = 500x² + 100x + 0.6x³ - 700x² + 400x - 300
p(x) = + 0.6x³+500x² - 700x² + 100x+ 400x- 300
p(x) = 0.6x³ - 200x² + 500x- 300
Hence the profit function is expressed as p(x) = 0.6x³ - 200x² + 500x- 300

Evaluate using order of operation and please show work
Answer:
10
Step-by-step explanation:
Given expression:
20 - [tex]\frac{15 + 3(5)^{2} }{5^{2} - 4^{2} }[/tex]
To solve this problem, we use the order of operation:
P - Parentheses
E - exponents
M - multiplication
D - division
A - Addition
S - Subtraction
Now solve the parentheses first;
= 20 - [tex]\frac{15 + 3x 25}{5^{2} - 4^{2} }[/tex]
= 20 - [tex]\frac{15 + 75}{5^{2} - 4^{2} }[/tex]
Now solve the exponents:
= 20 - [tex]\frac{15 + 75}{25 - 16}[/tex]
Now solve the division:
= 20 - [tex]\frac{90}{9}[/tex]
= 20 - 10
= 10
rewrite the equation 10=1,000 with an exponet that makes it true .
Answer:
[tex]10^3=1,000[/tex]
Step-by-step explanation:
The expression 10=1,000 is obviously false, but we can make it true by rewriting it with an exponent.
Note that 1,000=10*10*10
Or, equivalently:
[tex]1,000=10^3[/tex]
Thus, if we modify the original false expression and add an exponent 3 to the base 10, then it would be true:
Original:
10=1,000 => false
Rewritten true:
[tex]\boxed{10^3=1,000}[/tex]

The probability of a tourist visiting an area cave is 0.70 and of a tourist visiting a nearby park is 0.60. The probability of both places on the same day is 0.40. The probability that a tourist visits at least one of these two places is
The probability that the tourist visits atleast one of the two places is 0.90
Probability of cave visit, P(C) = 0.70
Probability of park visit = P(N) = 0.6
Probability of both = P(B) = 0.40
The probability of visiting atleast one of the two places can be defined thus :
P(Atleast one) = P(C) + P(N) - P(B) P(Atleast one) = 0.70 + 0.60 - 0.40P(Atleast one) = 0.90Therefore, the probability of visiting atleast one of the two places is 0.90

The science teacher gives daily homework. For a random sample of days throughout the year, the median number of problems is 5 and the IQR is 2. The Spanish teacher also gives daily homework. For a random sample of days throughout the year, the median number of problems is 10 and the IQR is 1. If you estimate the median number of science homework problems to be 5 and the median number of Spanish problems to be 10, which is more likely to be accurate? Explain your reasoning.
Answer:
SCIENCE SEEMS MORE ACCURATE
Step-by-step explanation:
The interquartile range (IQR) = difference between the upper and lower quartile (Q3 - Q1)
The median can be estimated as :
(Q3 - IQR/2) or (Q1 + IQR/2).
FOR SCIENCE:
MEDIAN NUMBER = 5
IQR = 2
IQR = Q3 - Q1
Q3 = median + IQR/ 2 = 5 + 2/2 = 6
Q1 = median - IQR/2 = 5 - 2/2 = 4
FOR SPANISH:
MEDIAN = 10
IQR = 1
IQR = Q3 - Q1
Q3 = median + IQR/ 2 = 10 + 1/2 = 10.5
Q1 = median - IQR/2 = 10 - 1/2 = 9.5
Science has a lower median score and an interquartile range which is reasonable wider than Spanish with a larger median value (but a very narrow interquartile range).
g Problem 7. (10 points) A random sample of 100 Cooper County residents showed that 18 are college graduates and a second random sample of 50 Boone County residents showed that 28 are college graduates. Round your final answer to each part to three decimal places, but do not round during intermediate steps. The relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is
Answer:
The relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is 3.11.
Step-by-step explanation:
Denote the events as follows:
C = Cooper County resident
B = Boone County resident
G = graduate
NG = non-graduate
The information provided is summarized as follows:
G NG Total
C 18 82 100
B 28 22 50
Total 46 104 150
Compute the relative risk of being a college graduate for Boone County residents as compared to Cooper County residents as follows:
[tex]\text{Relative Risk}=\frac{\text{Graduates in Boone County}}{\text{Graduates in Cooper County}}[/tex]
[tex]=\frac{28/50}{18/100}\\\\=\frac{28}{50}\times \frac{100}{18}\\\\=3.11111\\\\\approx 3.11[/tex]
Thus, the relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is 3.11.
The relative risk of remaining a college graduate for Boon County residents in comparison to Cooper County residents would be 0.500
Relative risk:Relative risk is used in the statistical analysis of the data of ecological, cohort, medical, and intervention studies, to estimate the strength of the association between exposures (treatments or risk factors) and outcomes. Mathematically, it is the incidence rate of the outcome in the exposed group.
The relative risk is calculated by dividing the probability of an event for group 1 divided by the probability of an event occurring for group 2.

Simon score 4x10^2 points in a game. Joe scored 2x10^3 points in the same game. whose score is higher? how much higher?
Answer:
Joe scored higher by 1600
Step-by-step explanation:
Given
[tex]Simon = 4 * 10^2[/tex]
[tex]Joe = 2 * 10^3[/tex]
Solving (a): Which is higher?
First, we need to convert both numbers to whole numbers
[tex]Simon = 4 * 100[/tex]
[tex]Simon = 400[/tex]
[tex]Joe = 2 * 10^3[/tex]
[tex]Joe = 2 * 1000[/tex]
[tex]Joe = 2000[/tex]
2000 is greater than 400;
Hence, Joe score higher
Solving (b): By how much?
We simply calculate the difference
[tex]Difference = Joe - Simon[/tex]
[tex]Difference = 2000 - 400[/tex]
[tex]Difference = 1600[/tex]
