Step-by-step explanation:
To find the radius of a circle from the circumference, divide the circumference by pi, then, divide the quotient by 2.
65 is the circumference of Joe's bicycle.
65 ÷ 3.14 = 20.7006369427
20.7006369427 ÷ 2 = 10.3503184714
10.3503184714 ≈ 10.4
Therefore, 10.4 is the radius of the wheel rounded to the nearest tenth.

A graphic designer creates a logo in the shape of an ellipse. The equation x^2/64 + y^2/14.44 = 1, with units in centimeters,
represents the outer edge of the logo. How tall is the logo?
a. 3.8 cm
b. 7.6 cm
c. 8 cm
d. 16 cm
Using the equation of ellipse, the height of the logo is 7.6cm
What is equation for ellipse?The equation of ellipse having a center (h, k) is given as;
[tex]\frac{(x - h)^2}{a^2} + \frac{(y - k)^2}{b^2} = 1[/tex]
where a is the semi-major axis and b is the semi-minor axis. The major axis is the longer of the two axes, and the minor axis is the shorter of the two axes. The center of the ellipse is the point (h, k).
The graph of an ellipse is a closed curve that is similar to a circle, but it is not a circle. The ellipse is wider than it is tall if a > b, and it is taller than it is wide if a < b.
In the given problem;
The equation for an ellipse is
[tex]\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1,[/tex] where a is the semi-major axis and b is the semi-minor axis. In this case, a = √64 = 8 and b = √14.44 = 3.8
Since b = 3.8, the height of the logo = 2b = 2 * 3.8 = 7.6cm

There are eight black balls and two white balls in a bag. What is the probability of picking one black ball without looking?
Answer:
8/10 or simplified will be 4/5
Step-by-step explanation:
Since there are 8 black balls and 10 balls in total, this is the probability
The probability of picking one black ball without looking is, 4/5.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, There are eight black balls and two white balls in a bag.
So, N(B) = 8 and N(W) = 2.
The sample space N(S) = 8 + 2 10.
Therefore, The likelihood of randomly selecting one black ball is,
P(B) = N(B)/N(S).
P(B) = 8/10.

The final exam grade distribution for all students in the introductory statistics class at a local community college is displayed in the table, with A = 4, B = 3, C = 2, D = 1, and F = 0. Let X represent the grade for a randomly selected student from the class.
What is the standard deviation of the distribution?
A) 1.16
B) 1.08
C) 1.41
D) 2.98
The standard deviation of the distribution is 1.08.
Option B is the correct answer.
What is a standard deviation?The standard deviation measures how spread out the data is from the mean, and it is a measure of the average distance of the data points from the mean.
We have,
To find the standard deviation of the distribution, we first need to calculate the expected value (mean) of X.
The expected value of X is:
E(X) = (4)(0.4) + (3)(0.32) + (2)(0.17) + (1)(0.08) + (0)(0.03)
= 1.6 + 0.96 + 0.34 + 0.08 + 0
= 2.98
Next, we need to calculate the variance of X:
Var(X) = (4 - 2.98)²(0.4) + (3 - 2.98)²(0.32)
+ (2 - 2.98)²(0.17) + (1 - 2.98)²(0.08) + (0 - 2.98)²(0.03)
= 0.64(0.4) + 0.0004(0.32) + 0.7921(0.17) + 5.4084(0.08) + 8.6404(0.03)
= 0.256 + 0.000128 + 0.134257 + 0.432672 + 0.259212
= 1.082
The standard deviation of X is the square root of the variance:
So,
SD(X) = √(Var(X))
= √(1.082)
= 1.04 (approximately)
Thus,
The standard deviation of the distribution is 1.08.

A six-sided die is rolled two times. What is the theoretical fractional probability that the first number is even and the second number is odd?
Answer:
The theoretical probability that the first number is even and the second number is odd is [tex]\frac{1}{4}[/tex].
Step-by-step explanation:
Since each dice has six sides, and there are two die, the total amount of different outcomes are [tex]6^2[/tex] or 36. The probability of getting an even number on the first roll is [tex]\frac{3}{6}[/tex] or [tex]\frac{1}{2}[/tex], and the probability of getting an odd number on the second roll is also [tex]\frac{3}{6}[/tex] or [tex]\frac{1}{2}[/tex], so the probability of getting an even number on the first roll and an odd number on the second roll is [tex]\frac{1}{2} * \frac{1}{2} = \frac{1}{4}[/tex].

the table shows the linear relationship between the average height in feet of trees on a tree farm and the number of years till the trees were planted,
what is the rate of change of the average height and feet of the trees on the farm with respect to the number of years since the trees were planted?
Step-by-step explanation:
the equation :
Hn = 7n + 3
where :
Hn : the height of trees at year to-n
n : year to-n (n = 1,2,3,...)
so, the rate of change : increasing 7 feet per year.
The rate of change of the average height and feet of the trees on the farm with respect to the number of years will be 7.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope could be positive or negative.
The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.
The rate of change also refers to the slope.
The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by
Slope = (y₂ - y₁)/(x₂ - x₁).
Taking two points (1,10) and (3,24)
Slope associated with these;
(24-10)/(3-1) = 7
Hence "The rate of change of the average height and feet of the trees on the farm with respect to the number of years will be 7".

the parent cosine function is transformed to create the function m(x) =-2cos(x+π). which graphed function has the same amplitude as function m
Answer: Graph D
Step-by-step explanation: Got it right on plato
The graph of a function with the same amplitude as m(x) is graph D.
Which graphed function has the same amplitude as m(x)?
The general cosine function is written as:
f(x) = A*cos(kx) + M
Where A is the amplitude, k is the angular frequency, and M is the midline.
In our case:
m(x) = -2*cos(x+π).
The amplitude is -2, which means that the distance between a peak and a trough must be twice the absolute value of the amplitude:
2*|-2| = 4
With this in mind, the only graph that meets this requirement is the graph D.

Sara was thinking of a number. Sara divides by 2, then adds 10 to get an answer of 6. What was the original number?
Answer:
The original number was -8
Step-by-step explanation:
You can find this out because -8 divided by 2 is -4 and then plus 10 would become 6
Answer:
-8
Step-by-step explanation:
We know that Sara has a number by which she divides by 2, added 10 and ended up with 6. We are then asked to find the original number she had in mind.
To solve, we need to go backwards, starting with the original number, and applying all the steps she did but with the opposite operation.
6 is her ended number, we know before she added 10, so subtract 10 from 6:
[tex]6-10=-4[/tex]
Now we know that she divided by 2, therefore multiply -4 by 2:
[tex]-4*2=-8[/tex]
-8 was Sara's first number.
