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:
5.4
Step-by-step explanation:
Notice that if you create a line that joins line 2.4 and line 9.6 you then form a right triangle with a hypotenuse equal to the radius. Then use the Pythagorean Theorem to solve for the radius:
(4.8^2)+(2.4^2)=C^2
23.04+5.76=C^2
28.8=C^2
√28.8=√C
5.4=C

Answer:
Area of a rectangle = Length × width
So ; Length = 2x + 3
I hope I helped you^_^
The first 3 are functions as their x coordinate (number on the left side of the parentheses) is not repeated in any of the other parentheses
