Step-by-step explanation:
This exercise uses the radioactive decay model The burial cloth of an Egyptian mummy is estimated to contain 60% of the carbon-14 it contained originally. How long ago was the mummy buried? (The half-life of carbon- 14 is 5730 years. Round your answer to the nearest ten years.)
Answer:
4257 years
Step-by-step explanation:
Given that:
Half-life of carbon 14 (t1/2) = 5730
Estimated carbon 14 content = 60% of amount of carbon 14 = 0.6
Using the model :
m(t) = mo*e^-rt
Decay rate (r) = In2/t1/2 = 0.00012
mo = initial mass
Hence,
Mass of carbon 14 in mummy m(t) = 0.6mo
0.6mo = mo*e^-(0.00012 * t)
0.6 = e^-(0.00012 * t)
Take the ln of both sides
In(0.6) = - 0.00012t
−0.510825 = - 0.00012t
t = 0.510825 / 0.00012
t = 4256.875
t = 4257 (nearest whole number)

What value of x is in the solution set of 9(2x + 1) < 9x - 18?
A. -4
B. -3
C. -2
D. -1
Answer:
b. -3
Step-by-step explanation:
9(2x+1) < 9x-18
(distribute the 9)
18x+9 <9x-18
(subtract 9 from both sides)
18x<9x-27
(subtract 9x from both sides)
9x<-27
(divide both sides by 9)
x<-3

In ΔXYZ, the measure of ∠Z=90°, ZY = 4, XZ = 3, and YX = 5. What ratio represents the tangent of ∠X?
Answer:
[tex]tan\ X= \frac{4}{3}[/tex]
Step-by-step explanation:
Given
[tex]Z=90\°[/tex]
[tex]ZY = 4[/tex]
[tex]XZ = 3[/tex]
[tex]YX = 5[/tex]
Required
Determine tan x
This question can be illustrated using the attached image
Tan of an angle is calculated as:
[tex]tan \theta = \frac{Opposite}{Adjacent}[/tex]
In this case, it is:
[tex]tan\ X= \frac{ZY}{XZ}[/tex]
Substitute values for ZY and XZ
[tex]tan\ X= \frac{4}{3}[/tex]
Hence, the required ratio is 4/3
Answer:
4/3

Step-by-step explanation:
A track team contains sprinters numbered 1,2,3,4,5 and distance runners numbered 1,2. Let S be the event of selecting a sprinter, D the event of selecting a distance runner, E the event of selecting an even numbered runner, and the event of selecting an odd runner. Selecting the sprinter numbered 1 is one outcome of which of the following events? Select all correct answers. Select all that apply: O DANDO ODORE DORO 00 OE' OS AND E
Answer:
D or O
E'
Step-by-step explanation:
Because the runner is a sprinter and the number is odd, the runner is an example of S and O. Therefore, it is also an example of E′ (not even) and D OR O.
For sprinter numbered 1 is outcome of S, D and O events.
Events to be determine that contain sprinter number 1. We have number of events that is for sprinter, distance runner, odd numbered, even numbered as S,D,O and E respectively.
Sample space = (1, 2, 3, 4, 5).
Probability can be defined as the possibility of the desired event to be happened.
Here, Numbered 1 is odd number, a sprinter and also a distance runner.
So, Numbered 1 is contain in S, D and O.
Thus, for sprinter numbered 1 is outcome of S, D and O events.

For a certain experiment, the available experimental units are 12 people—six females (f) and six males (m). Use (1f, 2f, 3f, 4f, 5f, 6f) to denote the females and (1m, 2m, 3m, 4m, 5m, 6m) to denote the males. There are to be six treatment groups: A, B, C, D, E, and G. If a randomized block design is used, with the experimental units blocked by gender, which assignment of treatments is not correct? (5 points) A: (2f, 1m), B: (1f, 2m), C: (6f, 3m), D: (4f, 4m), E: (3f, 5m), G: (5f, 6m) A: (6f, 5m), B: (2f, 4m), C: (3f, 3m), D: (4f, 2m), E: (5f, 1m), G: (1f, 6m) A: (1f, 1m), B: (2f, 2m), C: (3f, 3m), D: (4f, 4m), E: (5f, 5m), G: (6f, 6m) A: (1f, 2f), B: (1m, 2m), C: (3f, 3m), D: (4f, 4m), E: (5f, 5m), G: (6f, 6m)
Answer:
I believe the correct answer would be the last one.
Step-by-step explanation:
The units are supposed to be blocked by gender. However, the first two units in the final option are blocked with two females in one group, and two males in the next. This is inconsistent with the blocking method used for the rest of the units.
The randomized block design is adopted to minimize the risk of systematic error in an experiment. The incorrect assignment of treatment is ;
(1f, 2f), B: (1m, 2m), C: (3f, 3m), D: (4f, 4m), E: (5f, 5m), G: (6f, 6m)Since the units are blocked by gender, then each of the treatment groups should include atleast one of each gender.
For all the assignments given, only the last assignment include groups which contain only one of the gender ; (1f, 2f), B: (1m, 2m),

Let x = 2 + 8i and xy = –2 + 26i. What is y?
Answer: 3+i
Answer:
3 + i
Step-by-step explanation:
The solution for the complex function is equal to y = 3 + i.
What is a complex function?The function which is made up of the real numbers, as well as imaginary numbers, are called complex numbers these numbers are represented by a +ib form where the first part is the real part and the second part is the imaginary form.
The given complex functions are x = 2 + 8i and xy is -2+ 26i. The value of y will be calculated as below:-
xy = -2+ 26i.
y = ( -2+ 26i ) / x
y = ( -2+ 26i ) / ( 2 + 8i )
The value of the function will be calculated by rationalizing the function. When p and q are integers and q is not equal to zero, a result is a rational number, which has the form p/q. This ratio is between two integers.
The fundamental distinction between a fraction and a rational number is that fractions are always positive while rational numbers can be either positive or negative.
[tex]y =\dfrac{-2+26i}{2+8i} = \dfrac{-1+3i}{1+4i}[/tex]
[tex]y =\dfrac{-1+3i}{1+4i}\times \dfrac{1-4i}{1-4i}[/tex]
[tex]y = \dfrac{-1+4i+13i+52}{1+16}[/tex]
[tex]y = \dfrac{17i+51}{17}[/tex]
y = 3+i
Therefore, the solution for the complex function is equal to y = 3 + i.
