Answer:
10
Step-by-step explanation:
f(x) = 3x + 1
f^-1 = x-1/3 , it is known as inverse function.
f(3)= 3*3 +1
=9+1
=10
To find inverse,
x=3x + 1
y=3x+1
Exchanging the position or x and y
x=3y+1
x-1=3y
.•. y=x-1/3

The value of x that makes the equation 
true is x=53.67
Step-by-step explanation:
We need to find the value of x that makes the equation true
The equation given is:
Divide both sides by 6
So, the value of x that makes the equation true is x=53.67

Answer:
B
Step-by-step explanation:
A. matched-pair t-test is used ot deterrmine whether two samples are different because sometihng has changed and there are two distributions or there is effectively one distribution. In this scenario only mean of two population is being compared and not the effect of any variable
B. two sample t-test is used to determine whether average between two groups is significantly different or not. In this scenario, mean values of two populatinos are being compared.
C. ANOVAD is used to determine whether means of three or more statistically independent groups are significantly different or not. In this scenario, we have only two groups.
D. Chi-squaed test is used to test relationships between two variables. In this scenario, no relationship is being tested.
E. Inference of regression is used to determine how one population of x-values is dependent on another population of y-values based on the each individual sample values. In this scenario, we are not comparing individual values of two population
Answer:
Step-by-step explanation:
<B and <D = angles
AD and BC = sides
<1 and <4 = angles
so on each side it has 1side and 2 angles, so the conclusion would be: that triangle is going to be ASA. Thank you for asking this question and I'll be happy to Obliged.
