Answer:
~91 chirps/min
Step-by-step explanation:
This exercise is asking us to estimate based on the values in the table. If we know the temperature is 65°F, let's find the closest values given to interpolate (assuming the data is fairly linear, which it appears to be).
Looks like the closest ones are 60° and 68°. We will look at their corresponding chirps/min and guess a number in between those two.
60° -> 81 chirps/min
68° -> 97 chirps/min
Because 65 is closer to 68 than 60, we expect our result to be closer to 97 than 81.
slope = rise/run
=
= 2 chirps/min/°F. So for every °F increase, we expect to increase by 2 chirps/min.
60+5 = 65, so let's add 2*5 = 10 chirps/min to 60 to get 91 chirps/min. This corresponds with what we would have guessed.
120 cm2
132 cm2
156 cm2
276 cm2
Since the squarebase has side 6 cm and triangular side has height 10 cm, the total surface area of square pyramid is 156 cm²
A square pyramid has a square base and four triangular sides, its surface area, A = area of square base + 4 × Area of triangular side.
Area of square base
Area of square with side, L is A = L²
Area of triangularbase
Area of triangle with height and base, L which is the length of the square base is A' = 1/2Lh
Thus, total surface area of square pyramid ,
A" = L² + 4 × 1/2Lh
= L² + 2Lh
Given that the length of the square base is 6 cm and the height of the triangular side is 10 cm.
Now substituting the values of the variables intot he equation, we have
A" = L² + 2Lh
A" = (6 cm)² + 2 × 6 cm × 10 cm
A" = 36 cm² + 120 cm²
A" = 156 cm²
So, the total surface area of square pyramid is 156 cm²

Answer:
C) 156cm²
Step-by-step explanation:
1. 6x6=36
2. 6x10=60
3. 60/2=30
4. 30x4=120
5. 120+36=156cm²
The classification of each quantity as either a parameteror statistic is given thus :
a) X: parameter - A numerical summary of a population, and X represents a population parameter.
b) S: statistic - A numerical summary of a sample, and S represents a sample statistic.
c) o: statistic - Similarly, "o" represents a sample statistic, as it is used to denote the sample standard deviation.
d) u: parameter - "u" represents a population parameter, often used to denote the population mean.
