You have 3 quarters, 5 dimes, 7 nickels, and some pennies.-if the ratio of dimes to the total number of coins you ha e is 1:4, how many pennies are there?
The number of pennies there are, given the types of coins you have are 5 pennies.
How to find the number of pennies ?Since we have 5 dimes, we can set up the equation:
1/4 = 5/x
where x is the total number of coins.
Solving for x, we can cross-multiply:
1x = 45
x = 20
So we have a total of 20 coins.
Subtracting the number of quarters (3), dimes (5), and nickels (7), we get:

The length of a rectangular frame is represented by the expression 3x + 6, and the width of the rectangular frame is represented by the expression 3x + 4. Write an equation to solve for the width of a rectangular frame that has a total area of 120 square inches.
The width of the rectangle is 10 inches
How to determine the width?The given parameters are:
Length = 3x + 6
Width = 3x + 4
Area = 120
The area of a rectangle is
Area = Length * Width
So, we have:
(3x + 6) *(3x + 4) = 120
Expand
9x^2 + 12x + 18x + 24 = 120
Evaluate the like terms
9x^2 + 30x - 96 = 0
Using a graphing calculator, we have:
x = 2
Substitute x = 2 in Width = 3x + 4
Width = 3 * 2 + 4
Evaluate
Width = 10
Hence, the width of the rectangle is 10 inches

Suppose that a classroom has 4 light bulbs. The probability that each individual light bulbs work is 0. 6. Suppose that each light bulb works independently of the other light bulbs. What is the probability that none of the 4 light bulbs work?.
Answer:
0.0256 or 16/625 or 2.56%
Step-by-step explanation:
The problem states that each light bulb operates independently of the other, so the probability doesn't change for each light bulb based on how many other light bulbs are working.
The probability of each light bulb working is 0.6 out of 1. However, we want the probability of it being broken.
1 - 0.6 = 0.4
This is the probability of one light bulb being broken. But there are 4 lightbulbs.
We can multiply 0.4 by itself 4 times, as the probability stacks.
0.4 * 0.4 * 0.4 * 0.4 = 0.0256 (Also achieved by raising 0.4 to the power of 4)
To get the percentage, multiply it by 100. 2.56%
0.4 is equal to 40% or 40/100. If you simply, that fraction is equal to 2/5
2/5 * 2/5 * 2/5 * 2/5 = 16/625 (Also achieved by raising 2/5 to the power of 4)
What is the sum of a° + c°?

230°
240°
Answer:
300°
Step-by-step explanation:
Given from the diagram:
Angle a° = 180° (Single angle on a straight line)
Angle c° + 60° = 180° (Sum of angles on a straight line)
Angle c° = 180° - 60° = 120°
Angle a° + c° = 180° + 120° = 300°
Answer:
a + c = 300°
Step-by-step explanation:
a = 180°
c = 180° - 60° = 120°
a + c = 180° + 120° = 300°

The term "transition matrix" is used in various contexts of mathematics. In linear algebra, it is sometimes used to represent changes in a coordinate matrix. In Markov chain theory, it is used as an alias for a stochastic matrix, a matrix that describes a transition.
The transition matrix P is regular if there are only positive entries in the power of P. If the transition matrix is regular, a Markov chain is a normal Markov chain. For example, if you take the power of the matrix D in succession, the entry for D will always be (or will be) positive.

A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the true proportion is 0.03. If 476 are sampled, what is the probability that the sample proportion will be less than 0.04
The probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.
The true proportion (p) is given to be 0.03.
Therefore, Mean (μ) = p = 0.03.
The standard error of sampling distribution can be calculated using the formula σ = √[{p(1 - p)}/n], where n, is the sample size, that is, n = 476.
Therefore, σ = √[{0.03(1 - 0. 03)}/476] = 0.00782.
Since, np = 14.28 and n(1 - p) = 461.72 are both greater than 5, we assume the sample is normally distributed.
Since, we are asked to find the probability that the sample proportion is less than 0.04, we using our calculator, enter as following:
Normalcdf(-100000000,0.04,0.03,0.00782), which gives us the value 0.8995 or 89.95%.
Thus, the probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.

36. Dennis set off from Town A at 10 A.M., driving at an average rate of speed of 52 mph. He reached
Town B at 2 PM. If William set off 1 hour 25 minutes earlier than Dennis and took the same route
at an average rate of speed of 40 mph., at what time would William reach Town B?
The time William would arrive in town B IS 1 : 47 pm.
What time will William arrive in town B?The first step is to determine the distance and the time of Dennis's travel.
Time = 14 hours (2 pm + 12) - 10 hours = 4 hours
Distance = time x average speed
4 x 52 = 208 miles
The second step is to determine the time of William's travel:
Distance / average speed = time
208 / 40 = 5.20 = 5 hours 12 minutes
Time William left for the trip = 10 am - 1 hour 25 minutes = 8 :35am
Time he would reach town B = 8 : 35am + 5 hours 12 minutes = 13 hours 47 minutes = 1 : 47 pm
