Diamond is playing a game. In the game she has to spin a spinner
that is divided into 4 equal sections of green, red, blue, and yellow.
What is the probability that on her first spin she will land on green
and then red on her second spin?
Answer: 1/16
In decimal form, this is equivalent to 0.0625
=====================================================
Explanation:
Each of the four sections are of equal area, so that means the probability of landing on any given color is 1/4.
The probability of landing on green first is 1/4, then followed by red is another 1/4. We multiply these fractions. This is valid because each event of spinning the spinner is independent of one another. None of the spins affect any others.
We then get (1/4)*(1/4) = (1*1)/(4*4) = 1/16
The probability of Diamond landing on the green on her first spin and then red on her second spin is 1/16.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required event / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Assuming that each section of the spinner has an equal chance of being landed on, the probability of landing on the green on the first spin is 1/4.
Since each spin is independent of the others, the probability of landing on red on the second spin is also 1/4.
To find the probability of both events happening, we multiply the probabilities of each event:
P(green and red) = P(green) × P(red) = 1/4 × 1/4 = 1/16
Therefore,
The probability of Diamond landing on the green on her first spin and then red on her second spin is 1/16.

The area of a rectangle is at most 400 square centimeters. Write an inequality to represent the possible values for the height, h, for the height. The length is 16cm for one side
Answer:
1ft≤h≤25ft
Step-by-step explanation:
The area of a rectangle is expressed as;
Area = Length * height
A = Lh
If the area of a rectangle is at most 400 square centimeter, this is expressed as;
A ≤400
≤ means at most i.e it can not be greater than 400
Lh ≤ 400
Given L = 16
16h ≤ 400
h ≤ 400/16
h ≤ 25
Hence the possible values of the height are with the range 1ft≤h≤25ft since the dimension can not be negative

Franklin lives in a state that charges property tax on vehicles. He has a SUV worth $1, and the yearly property tax is $12.38 for every $1, of value. How much will he pay in yearly property tax?
Answer: $12.38
Step-by-step explanation:
Property taxes are charged on vehicles and Franklin has an SUV. He will therefore be charged property taxes on the SUV.
The SUV is valued at $1.
The yearly property tax is $12.38 per $1.
Franklin's property tax will therefore be $12.38 because the SUV is worth $1.

What is the independent and dependent variable in this problem?
Answer:
The height (h) of the ball is termed as the dependent variable and the time (t) is called the independent variable.
Step-by-step explanation:
We know that the function
y = f(x)
where y is a function of x.
Here:
The input variable 'x' is called the independent variableThe output variable 'y' is called the independent variable because the value of output y depends upon the value of the input 'x'.Given the function of the height of the ball as a function of time is modeled by the equation
h(t) = -16t² + 90t + 5
As the height of the ball depends upon the time as the height of the ball is a function of time.
Thus, the height (h) of the ball is termed as the dependent variable and the time (t) is called the independent variable.

A x function should not have two y values for the same x value. Therefore, option C is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
In the graph C we can see for x value 1 there are two y-values 2 and 3.
For the x value 2 there are two y-values 2 and 3.
Because an x function should not have two y values for the same x value.

A tram has an initial velocity of 300m/minute ◦ It travels a distance of 0.5km in 20 seconds
◦ What is the acceleration of the tram in m/s2?
If you could please help me, it would be greatly appreciated?
Answer:
Step-by-step explanation:
[tex]d=vt-\frac{at^2}{2} \\ \\ a=\frac{2(d-vt)}{t^2} \\ \\ a=\frac{2(500-300(20)}{20^2} \\ \\ a=-27.5 \frac{m}{s^2}[/tex]
The acceleration of the tram is 1 m/s^2.
To find the acceleration of the tram, we can use the following equation:
acceleration (a) = (change in velocity) / (time taken)
First, let's convert the initial velocity to m/s:
Initial velocity = 300 m/minute
To convert to m/s, we need to divide by 60 (since there are 60 seconds in a minute):
Initial velocity = 300 m/minute ÷ 60 seconds/minute = 5 m/s
Now, let's find the final velocity. The tram travels a distance of 0.5 km in 20 seconds.
Distance traveled = 0.5 km = 500 m (since 1 km = 1000 m)
Time taken = 20 seconds
Now, we can find the final velocity (v) using the formula:
v = (change in distance) / (time taken)
v = 500 m / 20 seconds = 25 m/s
Next, we can find the change in velocity:
change in velocity = final velocity - initial velocity
change in velocity = 25 m/s - 5 m/s = 20 m/s
Finally, we can calculate the acceleration:
acceleration (a) = (change in velocity) / (time taken)
acceleration (a) = 20 m/s / 20 seconds = 1 m/s^2
So, the acceleration of the tram is 1 m/s^2.

Tommy makes $200,000 per year. Tommy's monthly taxes are 10% for Federal Income Tax, 4.2% for Social Security Tax, 1.75% for Medicare Tax, and 0.5% for Local Taxes. What is Tommy's monthly Take Home Pay?
Answer: $13,925
Step-by-step explanation:
Tommy makes $200,000 per year.
He then has to pay taxes of 10% for Federal Income Tax, 4.2% for Social Security Tax, 1.75% for Medicare Tax, and 0.5% for Local Taxes.
His total taxes are therefore:
= 10% + 4.2% + 1.75% + 0.5%
= 16.45%
Taxes in dollars are:
= Monthly salary * taxes
= (200,000/12 months) * 16.45%
= $2,741.67
Monthly take home pay:
= Monthly salary - monthly tax
= 200,000 / 12 months - 2,741.67
= 16,666.67 - 2,741.67
= $13,925
