Garden canes have lengths that are normally distributed with mean 208.5cm and standard deviation 2.5cm. what is the probability of the lenght of a randomly selected cane being between 205cm and 210cm
The probability of randomly selecting a can between 205cm to 210cm is 0.8765
Data;
Mean = 208.5cmstandard deviation = 2.5cmNormal DistributionTo solve this problem, we can simply use the formula of probability and substitute the value.
[tex]p\frac{(205-108.5)}{2..5} < \frac{x - 208.5}{2.5} < \frac{210 - 205.5}{2.5}\\p(-1.4 < z < 1.8)[/tex]
Rearranging the equation and solving for the z-values;
[tex]p(z < 1.8-p < z < -1.4)[/tex]
This becomes
[tex]p = 0.9641 - 0.0876 = 0.8765[/tex]
The probability of randomly selecting a can between 205cm to 210cm is 0.8765

8.A golfer swings a club about a pivot point. If the head of the club travels a distance of 26 feet and rotates through an angle of 5 radians, which of the following gives the distance the club head is from the pivot point?
The distance the club head is from the pivot point is about 5.2 feet.
What is a circle?A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.
Let r represent the radius of the circle, that is the distance the club head is from the pivot point. Hence:
Length of arc = angle in radians * radius
26 = 5r
r = 5.2 feet
The distance the club head is from the pivot point is about 5.2 feet.

how many 6/14 feet of rope can you make out of 49/14 peices of rope?
This word problem is another way of saying
How many times can 6/14 go into 49/14
To find this out we divide
(49/14)/(6/14)
We also know that dividing by a fraction is the same as multiplying
=(49/14)(14/6)
=49/6
≈8.16
As we just want how many segments of 6/14 feet rope, we can ignore the decimals/round down getting the answer
Eight pieces of rope can be made our of 49/14 piece of rope.

Find the area of this circle.
A= ?
5 in
Hint: First, plug in the value
of the radius into the
formula for r.
If radius, r = 5in., then we can compute that the area of the circle = 78.55in² or approximately 79in².
Using the formula, Area of Circle = πr²
It is given in the question, r = 5in and as we know that the value of π = 3.142
Now, putting the values from above in the formula of area of circle, we will get:
A = π × 5² = 3.142 × 25 = 78.55
= 79in² (to the nearest whole number).
The space a circle takes up in a two-dimensional plane is known as its area. Alternately, the area of a circle is the area contained within the circumference or boundary of the circle. The sum of the square units inside that circle is another name for it.

A team of 13 basketball players needs to

O Permutation; 39
O Combination; 60
O Combination; 78
O Permutation; 156
The selection of the basketball players is an illustration of combination
The number of ways the basketball players can be chosen is 78
How to determine the number of selectionThe given parameters are:
Number of players (n) =13
Players to select (r) = 2
The number of ways the players can be selected is calculated as:
[tex]^nC_r = \frac{n!}{(n -r)!r!}[/tex]
The equation becomes
[tex]^{13}C_2 = \frac{13!}{(13 -2)!2!}[/tex]
Evaluate the difference
[tex]^{13}C_2 = \frac{13!}{11!2!}[/tex]
Evaluate the factorials
[tex]^{13}C_2 = \frac{13 * 12 * 11!}{11! * 2}[/tex]
Evaluate the quotient
[tex]^{13}C_2 = 13 * 6[/tex]
Evaluate the product
[tex]^{13}C_2 = 78[/tex]
Hence, the number of ways the basketball players can be chosen is 78

In the year 2000, the height of an apple tree was
150 centimeters. In the year 2020, the same tree has
grown to 270 centimeters. What was the average rate
of change in the height of the tree from 2000 to 2020?
In other words: On average, how fast was the tree
growing? Include units.
Answer:
(270+150)/(2020-2000)= 21 - average rate of change in the height per year
Answer:
I think to get the average rate you subtract 150 from 270 centimetres you'll get 120 centimetres then subtract 2000 from 2020 to get 20 now to get the rate divide 120cm by 20 and you will get six so the rate is 6 cm per year
Show that ln(x^3 "-4x)" − ln(x^2 "-2x)=" ln(x + 2).
[tex] ln({x}^{3} - 4x) - ln(x {}^{2} - 2x ) [/tex]
can be written as;
[tex] ln( \frac{ {x}^{3} - 4x }{ {x}^2 - 2x } ) [/tex]
[tex] ln( \frac{x( {x}^{2 } - 4) }{x(x - 2)} ) = ln( \frac{x(x - 2)(x + 2)}{x(x - 2)} ) [/tex]
Now all you have to do, is divide the numerator and denominator by x and by (x-2)
to get,
[tex] ln( \frac{x(x - 2)(x + 2)}{x(x - 2)} ) = ln( \frac{x + 2}{1} ) = ln(x + 2) [/tex]
