Remark
Many calculators have a key that will do this in one step. Mine is one of them. So let's start with the answer and then we'll do it the long way.
9C3 = 84. You put it into your calculator as 9 2nF nCr 3 =
Solution
3*4*7 = 84 which is what you set out to show.
Depth of Hank descends = The point he reached - the point where he worked initially
= 57 - 10
= 47 ft
Hence, Hank descends 47 ft.
Ok so mean means average so exmple
mean of 1,2,3+5 would be (1+2+3+5)/4
(sum of terms)/(number of terms)=mean so
number of terms=5 since 5 oranges
sum=(46+39+53+61+49)
so mean=(46+39+53+61+49)/5=248/5=49.6
so the answer would be 49.6 (estimateed to be 50)
Answer:
Randomized block design
Step-by-step explanation:
In the scenario described above, the subjects which are the different car types are grouped into fixed units of 4 called blocks with each unit then assigned randomly to a particular treatment condition, which are the 4 different types of tire. In the end, the mean mileage for each block is taken and compared to that of the other blocks. This type of research design improves the reliability of the result obtained as it also eliminates the occurrence of systematic error in the course of our experiment.
A mathematical expression which best represents the perimeter of this triangle is (15h - 6k + 12m) centimeters.
<u>Given the following data:</u>
Length A = (5h – 4k) centimeters
Length B = (10h + 7m) centimeters
Length C = (5m – 2k) centimeters.
<h3>What is a triangle?</h3>
A triangle can be defined as a two-dimensional shape that comprises three (3) sides, three (3) vertices and three (3) angles.
<h3>How to calculate the perimeter of a triangle.</h3>
Mathematically, the perimeter of a triangle is given by this formula:
<u>Where:</u>
- A, B, and C are length of sides.
Substituting the given parameters into the formula, we have;
