Assume that we are interested in the average length of 1015 fishes in Square Lake, WI. Also assume that all information for all 1015 fishes in this lake is known. Suppose, the average length of all 1015 fishes in Square Lake is 98.06 mm. Derek randomly selects 50 fishes from the Square Lake and obtains and average length of 101.04 mm. Using this information, describe the Individual, Variable, Parameter and Statistic.
Answer is given below
Step-by-step explanation:
given data
average length of all 1015 fishes = 98.06 mm
randomly selects 50 fishes average length = 101.04 mm
solution
When we get here, we mean to measure, so here we measure a fish in a square lake. And the variable means that a fish varies from fish to fish, so the length of the fish in the squares parameter mean that all individuals in the population so the parameter is average length of all 1015 fish in square lakestatics is selct of individual in sample so statistic is average length of random sected so fish in square lakeLeon bought a dozen daisies for $3.75. To the nearest hundredth, approximately how much did Leon pay for each daisy?
Answer: $0.31
Step-by-step explanation:
A dozen = 12
Cost of 12 daises = 3.75
Cost of one daisy = 3.75/12 = 0.3125
0.3125 to the nearest hundredth = 0.31
What is the distance between-21 and 6 on a number line in units
Answer: 27
Step-by-step explanation:
-21 to 6= 27
The difference between the numbers -21 and 6 is 27.
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
Given that the two numbers are -21 and 6. The distance between the two numbers will be calculated as,
Distance = 6 - ( -21 )
Distance = 6 + 21
Distance = 27
Hence, the difference is 27.

If

and
g(x) = 5x +7
Find
g(f(x)) = [? ]x2 +
Help pls
The composite function g(f(x)) is equivalent to 10x^2 - 1
Composite functionsThis are also referred to as function of a function. Given the following functions;
f(x) = 2x^2 - 5
g(x) = 5x + 7
In order to determine the composite function g(f(x))
g(f(x)) = g(2x^2 - 5)
Replace x with 2x^2 - 5 in g(x) to have;
g(f(x)) = 5(2x^2 - 5) + 7
g(f(x)) = 10x^2 - 18
Hence the composite function g(f(x)) is equivalent to 10x^2 - 1

Write a ratio in simplest form to express 8 inches over 3 feet
Answer:
Step-by-step explanation:
8 inches : 3 feet
12 x 3 = 36 inches
8 inches: 36 inches = 2 inches: 9 inches
The ratio in simplest form to express 8 inches over 3 feet is 2:9.
To express the ratio of 8 inches to 3 feet in simplest form, we need to convert the measurements to a common unit.
Since both measurements involve length, we can convert inches to feet or feet to inches.
We know that 1 foot = 12 inches
So 3 feet = 12×3
=36 inches.
Now the ratio 8 inches over 3 feet is equal to 8 inches over 36 inches.
8/36
Divide numerator and denominator by 4:
2/9
Hence, the ratio in simplest form to express 8 inches over 3 feet is 2:9.

∠B = 126
Step-by-step explanation:
∠A = ∠B
where
∠A = 8x + 78°
∠B = 2x + 114°
8x + 78° = 2x + 114°
8x - 2x = 114 - 78
6x = 36
x = 36/6
x = 6
plugin x into ∠B = 2x + 114°
∠B = 2x + 114°
∠B = 2(6) + 114°
∠B = 126

Answer:
i think x=-1 and y=3. ....
Answer:
x = -1 , y = 3
Step-by-step explanation:
2x+5y = 13
-x+4y = 13
Decide whether to add or subtract the two equations by using Different Add Same Subtract (DASS) or in case below as its SUBTRACT
i apply (SDSS).
We subtract 5y as this is easier equation either positive prioritises or if both positive then easier number becomes priory.
Results to SDSS before substituting Y if 5y etc was subtracted
2x+5y = 13 Subtract -5
2x+5y -5y = 13 -5y
2x= 13 - 5y then Divide by 2
2x / 2 = 13/2 - 5y/2 Show then
x = 13 - 5y / 2 + 4y = 13 Simplify
simplify 13 - 13y / 2 as y = 3
as 13/2 = 6.5 and 2.5 +4 = 6.5
y = 3
Substitute y = 3
