Answer:
0.6384
Step-by-step explanation:
Given that:
10-mg Atorvastatin Placebo Headache 15 65 No headache 17 3
Hence the total of number of patients = 15 + 65 + 17 + 3 = 100 patients
The number of patients with headache = 15 + 65 = 80 patients
Also, C(n, x) is the number of combinations in which n items can be chosen taken x at a time it is given by the formula:
[tex]C(n,x)=\frac{n!}{(n-x)!x!}[/tex]
The the probability that if two different subjects they both had a headache = [tex]\frac{C(80,2)}{C(100,2)}=\frac{\frac{80!}{(80-2)!2!} }{\frac{100!}{(100-2)!2!} } =\frac{3160}{4950}=0.6384[/tex]
algebra 2b question, please help!! much appreciated, thank you.
what types of correlations do these first two graphs of the article show? select two answer choices: one for the first graph, and one for the second graph.
- a negative correlation between time and the amount of arctic sea ice
- no correlation between time and average yearly temperature
- a negative correlation between time and average yearly temperature
- no correlation between time and the amount of arctic sea ice
- a positive correlation between time and average yearly temperatures
- a positive correlation between time and the amount of arctic sea ice
Answer:
1st graph = a positive correlation between time and average yearly temperature
2nd graph =a negative correlation between time and the amount of arctic sea ice
The first graph in the article displays the relationship between time and the amount of Arctic sea ice Therefore the correct option is A.
There seems to be a negative correlation, as the amount of Arctic sea ice decreases over time. The graph shows a consistent downward trend in sea ice levels as time progresses, suggesting that as time increases, the amount of Arctic sea ice decreases. On the other hand, the second graph illustrates the relationship between time and average yearly temperature.
There appears to be no clear correlation between these two variables. The graph shows fluctuating temperature levels with no consistent trend over time. This lack of a discernible pattern indicates that there is no correlation between time and average yearly temperature. In summary, the first graph indicates a negative correlation between time and the amount of Arctic sea ice, while the second graph suggests no correlation between time and average yearly temperature.
Hence the correct option is A.

6. A chemist wishes to make 5 liters of an 7% acid solution by mixing a 10% acid
solution and a 5% acid solution. How many liters of each solution the chemist have to
use? Make a table with relevant quantities and show all steps.
Answer:
The chemist will mix 3 liters of the 5% acid solution and 2 liters of the 10% acid solution to get 5 liters of 7% acid solution
Step-by-step explanation:
Here, we are interested in finding the number of liters of each solution the chemist have to make use;
Let the number of liters of the 5% acid solution be x while the number of liters of the 10% acid solution be y
Mathematically;
x + y = 5 •••••••••(i)
Also, let’s work with the percentages now
( x * 5%) + (y * 10%) = (5 * 7%)
0.05x + 0.1y = 0.35 ••••••••(ii)
From i , x = 5-y
Substitute this into ii
0.05(5 -y) + 0.1y = 0.35
0.25 - 0.05y + 0.1y = 0.35
0.25 + 0.05y = 0.35
0.05y = 0.35 -0.25
0.05y = 0.1
y = 0.1/0.05
y = 2
But x + y = 5
x + 2 = 5
x = 5-2
x = 3

The numerical values of the area and the perimeter of a square field are in the ratio 5:2, while that of a square park are in the ratio 3:1. What is the positive difference between their areas?
Answer:
44
Step-by-step explanation:
If side = a
Then:
A = a², P = 4a for area and perimeterA/P = a²/4a = a/4 for are/perimeter ratioThe first case:
a/4 = 5/2 ⇒ 2a = 20 ⇒ a = 10 ⇒ a² = 100The second case:

Determine the account balance of a simple interest account if the principal is $10,000, the interest rate is 1.5%, and the time is 5 years.
Answer:
Capital: 2 400
Tasa: 5% = 5/100 = 1/20
Tiempo: 4 años
A) Interés = capital*tasa*tiempo
Interés = 2400*(1/20)*4
Interés = 480 soles
B) Interés = Capital*((1 + tasa)^tiempo+1)
Interés = 2400*((1 + 1/20)^4 + 1)
Interés = 2400*((21/20)^4 + 1)
Interés = 2400*(194 481/160 000 + 1)
Interés = 2400*(354 481/160 000)
Interés = 5 317,215Step-by-step explanation:

a rectangle has a length of 8 and a width of 4. four equal rectangles are drawn within that rectangle, creating the longest lengths possible for the rectangles. what is the sum of the perimeters of two of these equal rectangles?
Given:
A rectangle has a length of 8 and a width of 4.
Four equal rectangles are drawn within that rectangle, creating the longest lengths possible for the rectangles.
To find:
The sum of the perimeters of two of these equal rectangles.
Solution:
We have to draw 2 lines which are bisecting the length and width respectively, to divide a rectangle in 4 equal parts with longest lengths.
Half of length 8 = 4
Half of width 4 = 2
It means each rectangle have a length of 4 and a width of 2.
Perimeter of a rectangle is
[tex]Perimeter=2(length+width)[/tex]
[tex]Perimeter=2(4+2)[/tex]
[tex]Perimeter=2(6)[/tex]
[tex]Perimeter=12[/tex]
So, perimeter of each equal rectangle is 12 units.
Sum of the perimeters of two of these equal rectangles is
[tex]12+12=24[/tex]
Therefore, sum of the perimeters of two of these equal rectangles is 24.

a father was 25 years older than his son five years ago. if the product of the son and his father's ages then was 900 years. how old is the son now.
Answer:
25
Step-by-step explanation:
Let x represent the son's age now. 5 years ago, it was x-5, and the father's age was (x -5)+25 = (x+20).
The product of their ages at that time was 900, so we have ...
(x -5)(x +20) = 900
x^2 +15x -100 = 900
x^2 +15x -1000 = 0 . . . . subtract 900
(x +40)(x -25) = 0 . . . . factor
x = -40 or +25 . . . . these values make the factors zero
The son's age now is 25.

50 kg+2.7kg for each inch over 5 feet (A) find a linear model for an estimate of the ideal weight of a woman using w for the ideal body weight ( in kilograms) and h for height over 5 feet ( in inches) W=
Answer:
W = 50 + 2.7h
Step-by-step explanation:
A function shows the relationship between two variables (the independent variable and the dependent vaariable). The independent variable is a variable that is independent of any other variable, i.e it is the input of the function while the dependent variable is dependent on other variables hence it is the output of the function.
Given that the weight of a woman is 50 kg+2.7 kg for each inch over 5 feet. If h is the height over 5 feet ( in inches), the weight (W) can be represented by:
W = 50 + 2.7h
W is in kg
A base of a parallelogram is on the x-axis and the origin is located at the left endpoint of that base. Three consecutive vertices are (h, j), (0, 0), and (k, 0), where h > 0. What is the x-coordinate of the fourth vertex?
2h
k + h
2k
Answer:
k + h
Step-by-step explanation:
Given that;
The base of a parallelogram is on the x-axis, i.e., it is on the horizontal axis.
The origin (0,0) is located to the left endpoint of the base. This is followed by (k,0) on that same horizontal baseline, now the length of the upper base must be equal to the length of the lower base, from the (k,0) endpoint, the vertical slant line leading to the upper base endpoint is (h,j).
Therefore, the x-coordinate of the fourth vertex will be k unit distant from h.
i.e k+h.
Answer:
k+h

The required simplified value of the function [tex]f(-2) + 9[/tex] as is 13.
Given that,
f(x) = -3x - 2
To determine
[tex]f(-2) + 9[/tex]
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given function f(x) = -3x - 2
Put x = -2 and add the function with 9
= [tex]f(-2) + 9[/tex]
= -3(-2) -2 + 9
= 6 - 2 + 9
= 13
Thus, the required simplified value of the function as [tex]f(-2) + 9[/tex] is 13.
