The statement in this problem that does not represent a inferential statistic is given by:
c. 15% of the people surveyed have the first name hugo.
What is an inferential statistic?An inferential statistic is one that makes inference or predictions about a population based on a sample.
In this problem, an inferential statistic is the sample proportion of 15% for the population of Lyon, France or Europe(as Lyon is in France and France in Europe).
In option C, the inference is for the sample and not for any population, hence it is not an inferential statistic.

Solve the equation E = v + Ir for r
A. r = E-v / I
B. r = I(E - v)
C. r = v + I / E
D. r = E - v - I
Show ALL Work
Answer:
A. [tex]\text{r} = \frac{\text{E}-\text{v}}{\text{I}}[/tex]
Step-by-step explanation:
E = v + Ir
E - v = Ir (subtract by v on both sides)
(E-v)/I = r (divide by I on both sides)
[tex]\therefore \text{r} = \frac{\text{E}-\text{v}}{\text{I}}[/tex]

Answer: m=12
Step-by-step explanation:
Answer:
m=12
Step-by-step explanation:
m - 3 = 9
You have to make sure
that m stands alone,
that's making m the subject.
So -3 have to cross the equal to sign,
to become +3
m = 9 + 3
m = 12

Assuming that all the grapes have the same probability of being randomly picked:
a) 0.11b) 0.24How to find the probabilities?
We know that there are 8 green grapes and 15 red grapes on the bowl, so there is a total of 23 grapes.
a) Here we need to find the probability that both grapes are green. Remember that the probability of getting a green grape is equal to the quotient between the number of green grapes and the total number of grapes, this is:
P = 8/23
But then he must take another, because he already took one, the number of green grapes is 7, and the total number of grapes is 22, so for the second grape the probability is:
P' = 7/22.
The joint probability is the product of the two individual probabilities:
prob = (8/23)*(7/22) = 0.11
b) For the first green grape we know that the probability is:
P = 8/23
Then he must get a red grape. There are 15 red grapes and 22 grapes in total, so the probability is:
P' = 15/22
Then the joint probability is:
prob = (8/23)*(15/22) = 0.24

How to find the simple interest rate if P=$4,000. T=2 years . And I= $320
And pls explain how I can find simple interest in every question bc I’m stressing about math finals
Answer:
3.2
Step-by-step explanation:
Formula to find the simple interest rate :
S.I. = [tex]\frac{PRT}{100}[/tex]
Formula to find R (simple interest rate) :
R = [tex]\frac{100*S.I.}{P*T}[/tex]
Since you have I (interest amount), we can use this formula instead :
R = [tex]\frac{I}{PT}[/tex]
R = [tex]\frac{320}{4,000*2}[/tex] = 4%/year or 0.04
Now plug this into the first formula
S.I. = [tex]\frac{4,000*0.04*2}{100}[/tex] = 3.2

Write an equation to match each graph.
I already tried y=[x] that didn’t work
Answer:
y=|x|
Step-by-step explanation:
We know
general modulus function passes through origin as |0| is 0
And it's symmetric on both sides of y axis .
As it's not one -one function
Means
f(-1)=|-1|=1f(1)=|1|=1So the graph is y=|x|
Answer:
y = |x|
Step-by-step explanation:
The equation for the part of graph to the right of the y-axis is:
y = x where y ≥ 0
The equation for the part of graph to the left of the y-axis is:
y = -x where y ≥ 0
So we can see that both a positive and negative value of x gives the same positive value of y.
Therefore, we can create an equation for the graph by using the absolute value of x:
⇒ y = |x|
Absolute value means how far away a number is from zero.
"x" is x away from zero and "−x" is also x away from zero.
So the absolute value of x is x, and the absolute value of −x is also x.
The bars either side of the x shows that we want the absolute value of x.
In practice, think of "absolute value" as removing any negative sign in front of a number.
With y = x → when x = 1, y = 1 and when x = -1, y = -1
With y = |x| → when x = 1, y = 1 and when x = -1 we think of it as x = 1, so y = 1
