Answer: Choice 2
invalid. The inner circle is plants, and the outer circle is those with cells.
=========================================================
Further Explanation:
If we throw a dart at random, and we land in the inner circle (plants), then we automatically land in the outer circle (has cells).
Now imagine the dart landed in the "has cells" circle, but outside the smaller circle. This could be stuff like animal cells, bacteria, etc. So just because something has cells it does not automatically make it a plant. Saying "an iris has cells" is not enough info to be able to tell it's a plant or not. This means the conclusion of "irises are plants" is shaky at best.
This is why the overall argument structure is invalid.

Suppose that for a function g (x), g (4) = 7. Select all of the statements that are true.
A. 4 is in the range of g.
B. For a value a, it is possible that g (a) = 4.
C. For a value y, it is possible that g (4) = y.
D. The point (4,7) is on the graph of y = g (x).
E. The point (7,4) is on the graph y = g (x).
Answer:
B and D
Step-by-step explanation:
The wording in the answer choices make a huge difference. It is possible implies that there is a possibility
A is false. The range of a function is the output value of the function for the input value in the domain of the function. So we can say with certainty that 7 is in the range since it is an output. But we cannot state that 4 is in the range because we have only one output value 7 for g(4)
A good example is a constant function such as g(x) = 7. Here, whatever the value of x, the y value is always 7. This represents a horizontal line passing through y = 7. So the range is just a single number {7}
B can be true. It is possible but not a certainty that f(a) = 4 for some value of a. For example, consider the function g(x) = x + 3.
At x = 4, g(4) = 4 .1 + 3 = 7
At x = 1, g(1) = 1 + 3 = 4 so it is possible for 4 to be an output
C is false. A well-defined function has only a unique value for a specific input of x. So we cannot get two different values for a single x value.
D is true. Since at x =4, y = g(x) = 7, this corresponds to a point on the graph. The point will be (x=4, y =7) or (4,7)
E is false. The x, y coordinates have been interchanged in this answer choice
The true statements are B and D.
The wording in the answer choices make a huge difference.
It is possible implies that there is a possibility
A. 4 is in the range of g.
A is false.
The range of a function is the output value of the function for the input value in the domain of the function. So we can say with certainty that 7 is in the range since it is an output. But we cannot state that 4 is in the range because we have only one output value 7 for g(4)

So the range is just a single number {7}

B can be true.
It is possible but not a certainty that f(a) = 4 for some value of a.
For example, consider the function g(x) = x + 3.
At x = 4, g(4) = 4 .1 + 3 = 7
At x = 1, g(1) = 1 + 3 = 4 so it is possible for 4 to be an output.
C. For a value y, it is possible that g (4) = y.
C is false.
A well-defined function has only a unique value for a specific input of x. So we cannot get two different values for a single x value.
D. The point (4,7) is on the graph of y = g (x).
D is true.
Since at x =4, y = g(x) = 7, this corresponds to a point on the graph.
The point will be (x=4, y =7) or (4,7)
E. The point (7, 4) is on the graph y = g(x).
False. The statement doesn't provide any information about g(7), and we cannot determine whether the point (7, 4) lies on the graph of the function y = g(x) based solely on the given information.

an angle measures 2.8 degrees more than the measure of its supplementary angle. what is the measure of each angle?
The measure of each of the supplementary angles are: 88.6° and 91.4°.
What are Supplementary Angles?Based on the definition of supplementary angles, the sum of two angles that are supplementary equals 180 degrees.
Given the following:
Let one of the angles equal x
The second angle would be expressed as: x + 2.8
Therefore, we would have the equation:
x + 2.8 + x = 180 [supplementary angles]
2x + 2.8 = 180
2x = 180 - 2.8
2x = 177.2
x = 177.2/2
x = 88.6
Thus:
One of the angles = x = 88.6°
Th second angle is: x + 2.8 = 88.6 + 2.8 = 91.4°
Therefore, the measure of each of the supplementary angles are: 88.6° and 91.4°.

The Average return rate for the investment will be 3.2%.
The Return Rate can be defined as a profit that is made on investment .
In the Question
let the investment be "x" .
25% stocks in Company A have return rate of 6%.
Investment in Company A = (25% of x)
Return is 6% of investment = (25% of x) + 6% of (25% of x)
Return from company A= (25% of x)(1+0.06) ...as 25%=0.25 & 6%=0.06
= 0.25*x*(1.06) ...(i)
40% stocks in Company B have return rate of 2.5%.
Investment in Company B = (40% of x)
Return is 2.5% of investment = (40% of x) + 2.5% of (40% of x)
Return from company A = (40% of x)(1+0.025) ...
= 0.40*x*(1.025) ...(ii)
Stocks in Company C = 100 - 25 - 40 = 35%
35% stocks in Company C have return rate of 2%.
Investment in Company C = (35% of x)
Return is 2.5% of investment = (35% of x) + 2% of (35% of x)
Return from company C = (35% of x)(1+0.02) ...

A: 59
B: 170
C: 1,700
D: 5,882
Answer:
1,700
Step-by-step explanation:
5x10^-7 is 0.0000005, while 8.5x10^-4 is 0.00085
0.00085/0.0000005=1700
Thus5 x [tex]10^{-7}[/tex] is 1700 times smaller than 8.5 x [tex]10^{-4}[/tex].
Option C is the correct answer.
Given,
5 x [tex]10^{-7}[/tex] and 8.5 x [tex]10^{-4}[/tex]
We need to find how many times smaller is 5 x [tex]10^{-7}[/tex] than 8.5 x [tex]10^{-4}[/tex].
What are exponents?Exponents are the power of a given number.
Example: a²
a - base
2 - exponent
Compare 5 x [tex]10^{-7}[/tex] and 8.5 x [tex]10^{-4}[/tex].
5 x [tex]10^{-7}[/tex] can be written as 5 / 10000000
8.5 x [tex]10^{-4}[/tex] can be written as 8.5 / 10000
Now,
5 / 10000000 = 0.0000005
8.5 / 10000 = 85 / 100000 = 0.00085
We see that,
0.0000005 is less than 0.00085
Now,
0.0000005 x 1700 = 0.00085
5 x [tex]10^{-7}[/tex] is 1700 times smaller than 8.5 x [tex]10^{-4}[/tex].
We can also write as:
5 x [tex]10^{-7}[/tex] x 17 x 10 ²
= 5 x 17 x [tex]10^{-7}[/tex] x 10²
= 85 x [tex]10^{-7 + 2}[/tex]
= 85 x [tex]10^{-5}[/tex]
= 85/10 x 10 x [tex]10^{-5}[/tex]
= 8.5 x [tex]10^{-5 + 1}[/tex]
= 8.5 x [tex]10^{-4}[/tex]
Thus 5 x [tex]10^{-7}[/tex] is 1700 times smaller than 8.5 x [tex]10^{-4}[/tex].

A population of mold decays at a rate of 30 mold spores per day. If the initial population of mold spores is 1560 spores, how many days will it take for the population to be less than 1000 mold spores?
By using a linear equation, we can see that after the 19 day the population will be less than 1000 mold spores.
How many days will it take for the population to be less than 1000 mold spores?We know that the population decays at a rate of 30 spores per day, and we have an initial population of 1560 mold spores.
Then, the population of spores after x days is given by the linear equation:
P(x) = 1560 - 30*x
The population will be exactly 1000 spores when:
P(x) = 1000 = 1560 - 30*x
We need to solve that for x.
30x = 1560 - 1000 = 560
x = 560/30 = 18.67
So after 18.67 days the population is 1000, this means that after the 19 day the population will be less than 1000 mold spores.

Step-by-step explanation:
57 m / 30 m/s = time in the air = 1.9 s
vertical drop for 1.9 s
vertical d = 1/2 a t^2 = 17. 7 m
For the point P(13,
14) and Q(18, 9), find the distance
d(P,Q) and the coordinates of the midpoint M of the
segment PQ
given points P( 13 ,14) and Q( 18,9 )
we have to calculate distance
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}d = distance(x_1, y_1) = coordinates of the first point(x_2, y_2) = coordinates of the second point[/tex]
d= [tex]\sqrt{( 18-13)^2+(9-14)^2}[/tex]
d=5[tex]\sqrt{2}[/tex]
now calculating midpoints
s= 13+18 /2 =31/2
t= 14+9 / 2= 23/2

A crab moves at a speed of 0.14 kilometers per hour. How far can it travel for 0.25 hours?
Answer:
0.14×0.25= 0.035 KM
so it can travel 0.035KM in 0.25 hr
Answer:
0.035 kilometers
Step-by-step explanation:
Proportions:
0.14 kilometers ⇒ 1 hour
A kilometers ⇒ 0.25 hour
A = 0.14 kilometers * 0.25 hour / 1 hour
A = 0.035 kilometers
The total cost of an annual pass for admission to a national
park plus camping for x days can be modeled by the function
f(x) = 20x + 80. A senior citizen pays $20 less than half of
this price for x days. What is the total cost for a senior citizen to
go camping for three days in the park?
The total cost paid by the senior citizen for 3 days = $50
Function word problemsThe function representing the total cost of the annual pass is:
f(x) = 20x + 80
A senior citizen pays $20 less than half of this price for x days
The total cost paid by the senior citizen = [tex]\frac{f(x)}{2} -20[/tex]
The total cost paid by the senior citizen =[tex]\frac{20x+80}{2} -20[/tex]
Simplify the resulting expression:
The total cost paid by the senior citizen =10x + 40 - 20
The total cost paid by the senior citizen = 10x + 20
x represents the number of days
Substitute x = 3 into the resulting equation
The total cost paid by the senior citizen for 3 days =10(3)+20
The total cost paid by the senior citizen for 3 days = $50
