which of the following graphs shows the solution set to t > 4 or t < -1
The graph that shows the solution set of the inequality t > 4 or t < -1 is given by the image presented at the end of the answer.
How to graph the solution set of the inequality?The inequality for this problem is defined as follows:
t > 4 or t < -1.
It is a compound inequality, as it has two conditions.
The first condition is given as follows:
t > 4.
Which means that numbers to the right of t = 4 are graphed, with an open circle representing an open interval.
The second condition is given as follows:
t < -1.
Which means that numbers to the left of t = -1 are graphed, with an open circle also representing an open interval.
The open intervals are because none of the conditions contain the equal symbol.

An experiment consists of rolling a standard six-sided die once. Event A is "rolling a 5{}^{\prime\prime} and event B is "rolling an odd number."
Are the events dependent or independent? Why?
Select the option that correctly answers both questions.
A) Events A and B are dependent, because P(A)≠P(B|A).
B) Events A and B are independent, because P(A)=P(B|A)=1/12.
C) Events A and B are dependent, because P(B)≠P(B|A).
Events A and B are dependent, because P(A)≠P(B|A). The correct option is A.
How to illustrate the events?From the information, the experiment consists of rolling a standard six-sided die once. Event A is "rolling a 5 and event B is "rolling an odd number."
Events A and B are dependent because the outcome of event A (rolling a 5) affects the probability of event B (rolling an odd number). The probability of rolling a 5 is 1/6, while the probability of rolling an odd number given that you have already rolled a 5 is 0. The probability of rolling an odd number is 1/2, and thus P(A) ≠ P(B|A)
In simple terms, Events A and B are dependent because outcome of event A affects the probability of event B happening.

$108.96
Answer:
Sure, here is a more casual and friendly way to explain how to calculate the weighted dollar amount of the savings account:
"Hey there! To find out the weighted dollar amount of the savings account, you just need to do a little math. First, multiply the amount invested in the savings account by the return on investment (ROR). Then, divide that number by the total ROR for all investments.
So, if you have $2,700 invested in the savings account and it has an ROR of 3.6%, the weighted dollar amount of the savings account would be:
($2,700 * 3.6%) / (3.6% + 1.8% + 13.6% - 1.2%) = $104.04

According to this postulate, two triangles are congruent if their two angles and included sides are congruent with each other.
What do you meant by Congruence Postulate?If the sides and angles of one triangle are the same as the sides and angles of another triangle, then two or more triangles are said to be congruent. Three postulates—ASA (angle-side-angle), SAS (side-angle-side), and SSS—that are demonstrated in the lesson can also be used to assess for congruency.
If, for example, triangle ABC has a hypotenuse of 5 cm and a leg of 4 cm and triangle PQR has a hypotenuse of 5 cm and a leg of 4 cm, then these two triangles have the same dimensions and, according to the HL theorem, are congruent to one another.

f(x) = 4x² + 9x +9
Find f(-1)
Answer:
4
Step-by-step explanation:
To find f(-1), we can plug -1 into the equation in place of x and simplify:
f(-1) = 4(-1)² + 9(-1) + 9
f(-1) = 4 + (-9) + 9
f(-1) = 4 - 9 + 9
f(-1) = 4 - 0
f(-1) = 4
Therefore, f(-1) = 4.
Use function composition to determine if f(x) and g(x) are inverse functions.
f(x)=\sqrt[3]{x-1} and g(x)=x^3+1
By function composition, f(x) and g(x) are inverse functions
How to use function composition to determine if functions are inverse functions?A function is a relationship between inputs where each input is related to exactly one output.
f(x)= ∛(x-1) and g(x)=x³+1
To confirm the inverse relationship using composition.
If f(g(x)) = g(f(x)) then they are inverse functions
Let's confirm:
f(g(x)) = f(∛(x³+1))
= ( ∛((x³+1)-1 )
= ∛(x³)
= x
g(x)=x³+1
g(f(x)) = g(∛(x-1) )
= (∛(x-1))³ + 1
= x-1+1
= x
Since f(g(x)) = g(f(x)) then they are inverse functions

Each small box of paper weighs 30 pounds and each large box of paper weighs 75 pounds. A total of 18 boxes of paper were shipped weighing 900 pounds altogether. Graphically solve a system of equations in order to determine the number of small boxes shipped, x, and the number of large boxes shipped, y.
The paper company shipped 10 small boxes and 8 large boxes.
How to solve an equationAn equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the number of small boxes shipped and y represent the number of large boxes shipped.
Each small box of paper weighs 30 pounds and each large box of paper weighs 75 pounds.
A total of 18 boxes of paper were shipped, hence:
x + y = 18
y = 18 - x (1)
Also, they weighed 900 pounds, hence:
30x + 75y = 900
but y = 18 - x, hence:
30x + 75(18 - x) = 900
30x - 75x + 1350 = 900
x = 10
y = 18 - x = 18 - 10 = 8

Answer: LCM(6,8)
Step-by-step explanation: Each of six slices of the first pasta has the area 1%2F6 of the entire pan.
Each of eight slices of the second pasta has the area 1%2F8 of the original pan.
David will cut each 1%2F6 in 4 equal pieces to get 1%2F24.
he also will cut each 1%2F8 in 3 equal pieces to get 1%2F24.
Then he will meet his goal.
Notice that the number 24 is the Less Common Multiple of the numbers 6 and 8: 24 = LCM(6,8).
Answer:
There would be six pieces in each pan.
Step-by-step explanation:
1. To make the number of pieces in each pan equal, the total number must be the same.
2. 8 pieces from the first pan + 6 pieces from the second pan = 14 pieces.
3. Divide 14 by 2 to get the same number of pieces in each pan:
14/2 = 7
4. Round down 7 to get six pieces in each pan.

Suppose tortilla chips cost 29.5 cents per ounce. If a bag cost $3.91, how many ounces are in the bag of chips?
There are approximately 13.38 ounces of chips in the bag.
What is division?
Division is one of the four basic mathematical operations of arithmetic, along with addition, subtraction, and multiplication. It is the inverse operation of multiplication, and it is used to find out how many times one number is contained within another number.
To find out how many ounces of chips are in the bag, you can use the formula:
cost of bag / cost per ounce = number of ounces
In this case, you know that the cost of the bag is $3.91 and the cost per ounce of chips is 29.5 cents per ounce.
First, you need to convert the cost per ounce from cents to dollars. 29.5 cents is equal to 0.295 dollars (29.5 cents / 100 cents = 0.295 dollars)
So, you can substitute these values into the formula:
3.91 / 0.295 = 13.38
Hence, there are approximately 13.38 ounces of chips in the bag.
