The probability of the experiment is = 0.375, 0.665.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.The likelihood that an event will occur increases with its probability.A straightforward illustration is tossing a fair (impartial) coin.The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half.acc to our question-

Work out the perimeter of this 6-sided shape.
The perimeter of the rectangle is = 48cm
What is permeter of rectangle?The overall length of the outline determines a shape's perimeter in two dimensions. We add the lengths of all four corners of a rectangle to find its perimeter. Since the opposite sides of a rectangle are always equal, we must determine the length and width of the rectangle in order to determine its perimeter. The rectangle's perimeter can be expressed as the product of its length and width times two. As a linear measurement, the perimeter can be expressed in meters, centimeters, inches, feet, etc.Acc to our question-

Given g(x)=-x-4g(x)=−x−4, solve for xx when g(x)=10g(x)=10.
The solution for x in the function when the function g(x) = 10 is 4
How to determine the solution for x in the function?From the question, we have the following equation that can be used in our computation:
g(x)=x-4
To make the equation legible, we need to rewrite it
So, we have the following representation
g(x) = x - 4
Also from the question, we have
g(x) = 10
This means that we calculate x when g(x) = 10
Substitute the known values in the above equation, so, we have the following representation
10 = x - 4
So, we have the following equation
x - 4 = 10
Add 4 to both sides of the equation
So, we have the following representation
x - 4 + 4 = 10 + 4
Evaluate the equation
x = 14
Hence, the solution is 14

The probability a dry day is followed by a light rain day is 0.07.
Define probability.Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
Given.
Here, the markov chain's three possible states are listed as dry, light rain, and wet.
From the second number in the first row, the chance of a dry day followed by a light rain is calculated as follows: P(dry⇒ light) = 0.01.

find the ratio of 2 meters to 76 centimeters
The ratio of 2 meters to 76 centimetres is 50: 19.
How to find ratios of units?In mathematics, a ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.
In simpler terms, a ratio compares values.
Let's find the ratio of 2 meters to 76 centimetres as follows:
We have to first convert the units so they will be same.
Hence,
1 cm = 0.01 m
76 cm = ?
cross multiply
length in metres = 76 × 0.01
length in metres = 0.76 metres
Therefore, let's multiply the 2 units by 100.
0.76 × 100 = 76 metres
2 × 100 = 200 metres
In ratio, 200 : 76 will be simplified as 50 : 19

Rewrite the equation in Ax+By = C form. Use integers for A, B, and C. y+3=-4(x-6)
Answer:
4x + y = 21
Step-by-step explanation:
1. distribute in the parenthesis first, so the right side of the equation is not -4x+24
Right now the total equation looks like y+3 = -4x+24
2. Now we add the 4x to both sides to cancel it out on the left side, so we're left with:
4x+y+3=24
3. After that we can subtract the 3 from both sides to leave us with:
4x+y=21

Shipping Company A charges $14 plus $2.25 a pound to ship overnight
packages. Shipping Company B charges $20 plus $1.50 a pound to ship
an overnight package. For what weight is the charge the same for the two
companies?
For 8 pounds of weight, the charges be the same for both the companies.
Given, that To ship an overnight package
Shipping Company A charges $14 plus $2.25 per pound
Shipping Company B charges $20 plus $1.50 per pound
Let, the weight be w
And the cost of shipment by company A & B be A(w) & B(w) respectively.
According to the question,
A(w) = 14 + 2.25w
B(w) = 20 + 1.50w
Now, when charges be the same
A(w) = B(w)
14 + 2.25w = 20 + 1.50w
On subtracting 1.50w on both the sides, we get
14 + 2.25w - 1.50w = 20 + 1.50w - 1.50w
14 + 0.75w = 20
Now on subtracting 14 on both the sides, we get
14 + 0.75w - 14 = 20 - 14
0.75w = 6
On dividing both the sides by 0.75, we get
0.75w/0.75 = 6/0.75
w = 8
Hence, weight = 8 pounds.
For 8 pounds of weight, the charges be the same for both the companies.

The Z score of the individual with IQ 90 is -0.67.
It is given that the scores are Normally distributed.
The mean given is 100 while the standard deviation is 15.
Let the IQ distribution be X.
Hence X follows a Normal distribution X~N(100, 225)
where
100 = mean
225 = standard deviation
To find the Z score we need to convert the following into the standard normal distribution.
To do that we need to follow
Z = ((x - μ) / σ)
here
μ = mean of the distribution = 100
σ = standard deviation of the distribution = 15
x = 90
Hence the Z score is
Z = (90 - 100) / 15

PLEASE HELP ASAP!!! Determine if the sequence is arithmetic. If it is, what is the common difference?

Thank you!
Answer:
Yes it is
Step-by-step explanation:
Every new number is 3 less than the last number
n-3
Answer:
Yes, -3
Step-by-step explanation:
An arithmetic sequence is when the numbers in the sequence are subtracted or added by the same value everytime to get the next number. (NOT multiplied or divided, if it's that then it's a geometric sequence)
from 36 to 33, we can see the change is -3
from 33 to 30, it's also -3
from 30 to 37, it's also -3
The common difference is the difference between the two consecutive terms in the sequence, which is -3
Since it's subtracting or adding by the same value everytime to obtain the next value, this sequence is an arithmetic sequence, and the common difference is -3

Based on the amount that she paid in the first month, the amount Ronda will pay for the next month is $396.
When a loan is amortized, it means that one can pay it off by paying the same amount every period until they would have paid off both the loan and the associated interest.
The amortized amount contains:
A portion going towards the principal(debt )
A portion going towards the interest accumulated.

Jada is working on solving a quadratic equation, as shown here.
p^2−5p=0
p(p−5)=0
p−5=0
p=5
She thinks that her solution is correct because substituting 5 for p in the original expression p^2−5p gives 5^2−5(5), which is 25−25 or 0.
Explain the mistake that Jada made.
Writing only p = 5 is a mistake since p = 0 is also a solution of the quadratic equation
How to find the mistake she made in solving the quadratic equation?
Given the quadratic equation: p² −5p = 0
p² −5p = 0
p(p−5) = 0
p = 0 or p−5=0
p = 0 or p = 5
Jada made mistake in the 3rd step instead of him to break the equation into two parts and then equate them to zero i.e he neglected the part where p = 0 and only make use of p-5 = 0
Since the equation has two solutions, p = 0 and p = -5. Therefore, writing only p = 5 is a mistake because when p = 0 is substituted into p² −5p = 0, it also gives 0

A Pre-K teacher has a total of 4/5 ounces of paint. Th teacher puts 1/30 ounces of paint at each table. If the teacher sets up an equal number of tables in the 2 Pre-K classrooms, how many tables does he set up in each classroom?
Answer:
12 tables per classroom.
Step-by-step explanation:
We will assume that the teacher uses all of the 4/5 oz of paint. We can find how many samples of 1/30 oz are contained in the 4/5 oz by dividing:
(4/5)÷(1/30) = (4/5)*(30/1)
(4/5)*(30/1) = (120/5)
(120/5) = 24 samples of 1/30 oz paint in (4/5) oz total paint.
Each of the 2 Pre-K classrooms have the same number of tables, so we can divide 24 samples by 2 to find the number of tables in each classroom,
*24 samples/2 classrooms) = 12 tables/classroom
