Answer:
1/2 or 0.5.
Step-by-step explanation:
To calculate the probability of two cards chosen not including T, we need to determine the number of favorable outcomes (cards not including T) and the total number of possible outcomes.
From the provided sample space table:
The favorable outcomes for two cards not including T are:
P, M
P, P
P, R
P, M
R, M
R, P
R, R
R, T
There are 8 favorable outcomes.
The total number of possible outcomes is the number of cells in the table, which is 16.
Therefore, the probability of two cards chosen not including T is 8/16, which simplifies to 1/2 or 0.5.
Answer: 9/16
Step-by-step explanation:
hopefully (i think)
16 total options
9 don't include a T
so 9/16 don't include T
9/16 also don't include M, so they have equal probabilities, which makes sense since there are an equal number of each letter card

Answer: Follow these steps.
Step-by-step explanation:
Add the total number of members in the club : 24+45+281+50=400Decipher the number of girls from the percentage given by the total number of members : (18/100)*400 = 72Now subtract the previously existing number of girls from the present number of girls : 72-45=27Subtracting the new number of girls from the total children who joined the club will give the number of boys : 50-27=23Therefore 23 boys joined the club.

Write and solve an equation to show the answer.
Explain when to use division and when to use multiplication to solve an equation. Give examples to support your answer
Answer: 1,796
Step-by-step explanation:
We are given that : At the chicken ranch this morning there were 7,149 chicks.
i.e. The number of new chicks before today = 7,149
Later today some more chicks hatched. now the ranch has 8,945 chicks.
i.e. The number of new chicks after today = 8,945
Then, By Subtraction operation
Number of new chicks hatched today = ( Number of new chicks after today) - (Number of new chicks before today )
= 8,945- 7,149 = 1,796
Therefore , the number of new chicks hatched today = 1,796

The figure formed by (−3, 2), (−4, 1), and (−1, −5) is translated 3 units right and 5 units up. What are the coordinates of the new figure?
(0, 7), (−7, −4), (2, −10)
(−6, −3), (−7, −4), (−4, −10)
(0, 7), (−1, 6), (2, 0)
(−6, −3), (−1, 6), (−4, 0)
Translating the figure involves chaging the position of the figure
The coordinates of the new figure are (0, 7), (1 , 6), and (2, 0)
The coordinates of the new figure
The coordinates are given as:
(−3, 2), (−4, 1), and (−1, −5)
The rule of translation 3 units right and 5 units up is:
(x + 3, y + 5)
So, we have:
(−3 + 3, 2 + 5), (−4 + 3 , 1 + 5), and (−1 + 3, −5 + 5)
Evaluate the sum
(0, 7), (-1 , 6), and (2, 0)
Hence, the coordinates of the new figure are (0, 7), (1 , 6), and (2, 0)

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

A submarine is descending to examine the seafloor 2,100 feet below the surface. It takes the submarine 2 hours to make this descent. Write an equation to represent the relationship between the submarine's elevation and time.
Another submarine’s descent can be represented as y=-240x, where y is the elevation and x is time in hours. How long will it take this submarine to make the descent?
Answer:
-1050
Step-by-step explanation:
I know the answer because descending means going down so 2100 is the big number and its negative to if you do -2100 divided by 2 then you will get -1050.
It would take the submarine 8.75 hours to make the descent of 2100 feet.
Linear equationA linear equation is in the form:
y = mx + b
where m is the rate of change, y, x are variables, and b is the y intercept.
Let y represent the level of the submarine after x hours.
It takes the submarine 2 hours to make a descent of 2100 feet, hence:
y = mx
-2100 = 2m
m = -1050
y = -1050x
Given the equation y = -240x, for 2100 feet descent:
-2100 = -240x
x = 8.75 hours
It would take the submarine 8.75 hours to make the descent of 2100 feet.

Kevin's weekly salary is 865. He receives a 25% raise. How can Kevin find his new weekly salary? Select all that apply.
a. divide 865 by 0.25
b. divide 865 by 1.25
c. multiply 865 by 0.25
d. multiply 865 by 1.25
e. add 865 and 1/4 of 865
f. add 865 and 1 1/4 of 865
Answer:
Option d. (also option e depending on which way you want to calculate it)
Step-by-step explanation:
First, I should point out that percentage basically means 'out of one hundred' so 25% means '25 out of one hundred.' The value of the percentage increase = 25% × 865. The new value = 865 + The value of the percentage increase.
______________________________________
More Simple Explanation:
Alright, so this might not be a super 'mathematical' trick or related to this question but it still works. Basically we just have to convert 25% into a decimal which I do by moving the decimal point 2 numbers to the left. (Since we cannot see the decimal point in the percentage we automatically know that it stays at the end of 25 a.k.a 25.0) So now our number becomes 0.25 (we got rid of the percentage symbol). Now we just multiply 865 by 0.25 to get our answer!
______________________________________
More Mathematical Process *Basically the value and random useless stuff to know lol because my math teacher showed me this and I thought I needed to add this*:
1) Calculate the new value of the number increased by percentage of its initial value
The new value =
865 + The value of the percentage increase =
865 + (25% × 865) =
865 + 25% × 865 =
(1 + 25%) × 865 =
(100% + 25%) × 865 =
125% × 865 =
125 ÷ 100 × 865 =
125 × 865 ÷ 100 =
108,125 ÷ 100 =
1,081.25
2) Calculate the actual change (the difference) between the new value and the initial one
The actual change =
The new value - 865 =
1,081.25 - 865 =
216.25
(For positive numbers, the actual change = The value of the percentage increase)
