Step-by-step explanation:
-3x + 11x - 1 + 7x2 - 4x + 4
Solving like terms
7x2 + 4x + 3

I hope this helps
Step-by-step explanation:
180 Degree Rotation
When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.
Answer:
91.204 cubic feet
Step-by-step explanation:
We are given that
Height of great pyramid, h=480feet
Side of square base, a=755 feet
Height of Danny's pyramid, h'=480/100 feet
Side of square base of Danny's pyramid, a'=755/100 feet
We have to find the volume of Danny's pyramid if the volume of Danny's pyramid is 1/100 the size of great pyramid.
We know that
Volume of square base pyramid, V=
Where a= Side of base
h=Height of pyramid
Using the formula
Volume of Danny's pyramid=
Volume of Danny's pyramid=91.204 cubic feet
Answer:
- A. Paired-sample t-test. --- Wilcoxon Signed-Ranks T test
- B. Independent-sample t-test. --- Mann-Whitney U test
- C. One-way ANOVA, independent samples. --- Kruskal-Wallis H test
- D. One-way ANOVA, repeated measures. --- Friedman test
Step-by-step explanation:
- The nonparametric statistics is a branch of statistics, that seeks out the population distribution that is either being distributed freely or specifically.
- Wilcoxon Signed-Ranks T-test is a hypothesis test used to compare the two or pre related columns that can be matched and maybe a repeated measure on a single sample.
- The Mann-Whitney U test is a null hypothesis and states the probability of a random sample of X and Y from the population is greater than the X and that Y is greater than X.
- Kruskal-Wallis H test is a test of one variance analysis and tests that sample originates from the same distribution.
- The Friedman test is used to find treatment across multiple tested attempts. It involves the ranking of the rows and then considering the values of the column.
Answer:
B) 9π in^2
Step-by-step explanation:
Circumference of a circle is C = πD
Divide 6π by π to get 6 then divide by 2 to get the radius of the circle
Area of a circle is A = πr^2
6/2 = 3 3 = r
π(3)^2 = 9π
