The probability of spinning yellow, tossing heads, and selecting the number 2 is approximately 0.083325 or 8.33%.
To find the probability of spinning yellow, tossing heads, and selecting the number 2, we need to calculate the individual probabilities of each event and then multiply them together.
Given:
Spinner with three equal size sections (red, green, yellow)
Coin toss with two outcomes (heads, tails)
Two cards labeled with 1 and 2
Firstly calculate the probability of spinning yellow:
Since the spinner has three equal size sections, the probability of spinning yellow is 1/3 or 0.3333.
Secondly calculate the probability of tossing heads:
Since the coin has two possible outcomes, the probability of tossing heads is 1/2 or 0.5.
Thirdly calculate the probability of selecting the number 2:
Since there are two cards labeled with 1 and 2, the probability of selecting the number 2 is 1/2 or 0.5.
Lastly multiply the probabilities together:
To find the probability of all three events occurring, we multiply the individual probabilities:
Probability = (Probability of spinning yellow) * (Probability of tossing heads) * (Probability of selecting the number 2)
Probability = 0.3333 * 0.5 * 0.5
Probability = 0.083325
Therefore, the probability of spinning yellow, tossing heads, and selecting the number 2 is approximately 0.083325 or 8.33%.

Answer:
she rides her bike at a rate of 8mph during the second part of the trip.
Step-by-step explanation:
for the first part of the trip, she rides 18 miles in 2 hours which means that she bikes at a rate of 9 miles per hour.
subtracting 18 from 58 gives us the distance she biked during the second part of her trip (which is 40 miles). subtracting 2 from 7 gives us that she biked for 5 more hours. Putting this together means she biked 40 miles in 5 hours.
Now divide miles by hours [tex]\frac{40mi}{5hrs} =8mph[/tex] to get your average rate of change for the second part of the trip.
A friend asked lara to help her divide 456.3 by 100. what should lara tell her? a. move the decimal point three places to the right. b. move the decimal point two places to the right. c. move the decimal point three places to the left. d. move the decimal point two places to the left.
Answer:
Step-by-step explanation:
The correct answer is D. If we are multiplying by 10 we would move the decimal place one place to the right to show that the number is now 10 times bigger. If we multiply by one hundred. We are getting 100 times bigger, so we would move the decimal place 2 places to the right.
The opposite is true if we are dividing. Instead of moving the decimal to the right to show that the number is getting bigger, we move to the left to show that the number is getting smaller. If we are getting smaller by 10, we would move the decimal one place to the left. In this case, we are getting 100 times smaller so we move the decimal two places to the left.

Full factor of 32a^3+ 12a^2
Answer:
4a²*(9a + 3)
Step-by-step explanation:
Factorize:Prime factorize 32 and 12. Then find GCF.
32a³ = 2 * 2 * 2 * 2 * 2 * a³
12a² = 2 * 2 * 3 * a²
GCF = 2 * 2 * a² = 4a²
32a³ + 12a² = (4a²*9a) + (4a²*3)

The table shows how far a distance runner has traveled since the race began. what is her average rate of change, in miles per hour, during the interval 0.75 to 1.00 hours?
The average rate of change will be 5 miles per hour from 0.75 to 1 hour.
The average rate of change is the ratio of change in the y-value or the function value by the change in the x-value.
So according to the question,
the interval between 0.75 to 1 hour is =1-0.75=0.25 hour.
At 0.75 hours elapsed, the distance traveled is 3.5 miles
at 1 hour elapsed, the distance traveled is 4.75miles.
during the interval, 0.75 hours to 1-hour distance travelled=4.75-3.5=1.25 miles.
the average rate of change will be = change in distance traveled during the interval/interval time.
=(4.75-3.5)/(1-0.75)=1.25/0.25=5 miles per hour
Therefore the average rate of change will be 5 miles per hour from 0.75 to 1 hour.

Step-by-step explanation:
a square inscribed in a circle means that the radius of the circle is the same thing as a line drawn from the center of the square to a corner.
this will give you the side measurements for a triangle (look at the attached picture). now use the Pythagorean theorem to find the hypotenuse aka the side length of the square. then multiply it by itself.
Answer: H
Step-by-step explanation:
Finding the DiameterIf we draw a line through a diagonal of the square, two triangles are formed. The angle opposite the diagonal is 90°, as all angles are 90° in a square. One of the properties of a circle state that the angle in a semicircle is always 90°, which means that the diagonal formed a semi-circle.
A semi-circle only forms when a diameter is drawn in a circle, making the diagonal a diameter. This will be useful information, as we can calculate the side length of a square using the length of its diagonal.
A diameter is just twice the length of a radius, so the diagonal of the square would be 6 cm.
[tex]2*3=6[/tex]
Finding the Length of One SideThe diagonal also splits the square into two 45-45-90 triangles. These triangles have a special property that their hypotenuse is √2 times each leg, and all legs are the same length.
Therefore, we can calculate the length of a leg by dividing the hypotenuse by √2.
[tex]\frac{6}{\sqrt{3}}[/tex]
The length of one side of the square is [tex]\frac{6}{\sqrt{3}}[/tex]
Finding the AreaAs we already know the length of one side, we can just square it to get the area.
[tex](\frac{6}{\sqrt{3}})^2[/tex]
[tex]\frac{6^2}{(\sqrt{3})^2}[/tex] [Properties of Exponents]
[tex]\frac{36}{3}[/tex]
[tex]12[/tex]
Hence, the area of the square is 12 cm².
30) A student has not been to class and must pass a 20 question true/false exam to continue in the course. The student will guess on every question and must get at least 14 correct to pass the test. What is the probability that the student will pass the test

In probability theory and statistics, the Bernoulli distribution, named after Swiss mathematician Jacob Bernoulli,[1] is the discrete probability distribution of a random variable which takes the value 1 with probability [tex]p[/tex] and the value 0 with probability [tex]{\displaystyle q=1-p}[/tex]. Less formally, it can be thought of as a model for the set of possible outcomes of any single experiment that asks a yes–no question. Such questions lead to outcomes that are boolean-valued: a single bit whose value is success/yes/true/one with probability p and failure/no/false/zero with probability q.
The student will pass if he at least answers 14 questions correctly .
This can be written as a Bernoulli distribution function [tex]P(Q=i)= 20C_{i} (\frac{1}{2} )^i(1-\frac{1}{2} )^(20-i)[/tex]
P(Q≥ 14) = P(Q=14) + P(Q=15) + P(Q=16) +P(Q=17) + P(Q=18)+ P(Q=19) + P(Q=20)
P(Q=14) = 20[tex]C_{14}[/tex][tex](1/2)^{20}[/tex]
P(Q=15) = 20[tex]C_{15}[/tex][tex](1/2)^{20}[/tex]
P(Q=16) = 20[tex]C_{16}[/tex][tex](1/2)^{20}[/tex]
P(Q=17) = 20[tex]C_{17}[/tex][tex](1/2)^{20}[/tex]
P(Q=18) = 20[tex]C_{18}[/tex][tex](1/2)^{20}[/tex]
P(Q=19) = 20[tex]C_{19}[/tex][tex](1/2)^{20}[/tex]
P(Q=20) = [tex]20C_{20}(1/2)^{20}[/tex]
On summing up all we get,
P(Q≥ 14) = (38760 + 15504 + 4845+ 1140 + 190 + 20 + 1)/2^(20)
= 15115/262144=0.057

The equation in function form is f(x)=-4x+80.
What is linear function?
A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0.
We can find the equation in function form as shown below:
We have given two points (5,60) and (10,40)
Slope of line
m = (40-60)/ (10-5)
m=-20/5
m=-4

y-60=-4x+20
y=-4x+20+60
y=-4x+80
