Answer:
A boxplot offers us information that can be used to compare two variables. In particular, if one variable is quantitative and the other variable is qualitative, a boxplot is generated for each category of the qualitative variable. Therefore, through this graph it is possible to analyze the relationship between the amount of money spent on food and the gender of the person.
A circular diagram offers information for a single variable, especially of a qualitative type.
A histogram offers us information for a single variable, especially quantitative type.
A relational analysis between two variables could be done using options (D) or (E), however one of the variables of interest is of qualitative type and the other is of quantitative type, so the scatterplot and the two-way table.

Step-by-step explanation:
Hello,
Basically, we need to prove that is irrational
Let s assume that is rational
it means that we can find p and q (q different from 0) two integers <u>with no common factors other than 1 </u>
so that
And then we can write that
So is even so it means that p is even
so is divisible by 2*2=4
as it means that is even, meaning q is even
wait, p and q are then even !? but by definition they have no common factors. This is not possible.
so our assumption that is rational is false
So it means that this is irrational
and then is irrational too
Hope this helps
10×14= 140hrs
1351/140=$9.64 per hour
Answer:
y = 128(4.926)^x
Step-by-step explanation:
Exponential function: y = ab^x
x = 0, y = 128
128 = ab^0
128 = a
--------------------
a = 128, y = 371,293, x = 5
371,293 = 128 x b^5
b^5 = ( 371,293 / 128 )
b = (fifth root) 5^√2900.7265625
b ≈ 4.926
----------------------------------------
y = 128(4.926)^x
I hope this helps!
