Answer:
Its d
Step-by-step explanation:A probability of 1 indicates an event will definitely happen.
The true statement is D; probability of 1 indicates an event will definitely happen.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence . An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty.
It is a numerical representation of the likelihood or likelihood that a particular event will occur, Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1.
The correct statement is D; A probability of 1 indicates an event will definitely happen.

What is the inverse operation do use to solve for t?
t - 19=2
We use addition, or rather the addition property of equality.
t-19+19=2+19

Step-by-step explanation:
Addition is the inverse operation.
inverses:
addition/subtraction
multiplication/ division

An online clothing company sells custom sweatshirts. The company charges $4.99 for shipping plus $20 for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Answer:
20x+4.99=y
Step-by-step explanation:
Each sweatshirt cost $20, but we don't know how many sweatshirts someone will buy so we use X, representing the amount of sweatshirts. There is a shipping charge of $4.99, so we have to add that to the cost of the sweatshirts. 20x+4.99. Y is the total cost.

Step-by-step explanation:
We know that 6z-31+something is going to be equal to 180 degrees, because it is supplementary. But what is that something? We see 67 degrees. Do you think this is a corresponding angle to the something that we need to find? Yes, it is! So we know that 6z-31+67 is equal to 180. So, z is 24. Now, since we know the value of the something (67 degrees because of corresponding angles) we can find yet another pair of supplementary angles. 67+x=180! Kind of neat, huh? So, x is equal to 113.

Please help. I don't know-how
Answer: 4
You would set this up like so:
125 ≤ 29.50 + 19.50x
Subtract 29.50 from both sides.
You should be left with 95.50 ≤ 19.50x
From here, you wanna divide both sides by 19.50 (we do this to isolate the x)
You would get 4.89.
Since Tamesha can't buy half a shirt, you don't wanna round up. So, the answer should be 4.
Step-by-step explanation:
Trust Milky. Milky smart!
Answer:
she can buy 4 shirts
Step-by-step explanation:
maximum that she can spend = $125
dress = $29.50
shirt = $19.50
first, take 29.50 and subtract it from 125
⇒ 125 - 29.50 = $95.50 remaining
then take 95.50 and it divide it by 19.50 to determine how many shirts she can buy
⇒ [tex]\frac{95.50}{19.50}[/tex] = 4.897
⇒ 4 shirts
to solve:
take 4 shirts and multiply it by 19.50
⇒ 4 x 19.50 = $78
then take the product and add 29.50
⇒ 78 + 29.50 = 107.50
take the maximum money and subtract 107.50 from it
⇒ 125 - 107.50 = 17.5
Tamesha would have $17.50 remaining.

When Shawn cleaned his room he found that the ratio of clean clothes to dirty clothes was 3 to 5 if 46 articles of clothing were discovered how many were clean
Answer:
17.25
Step-by-step explanation:
Ratio of clean clothes to dirty clothes = 3 : 5
Clean clothes = 3
Dirty clothes = 5
Total ratio = 3 + 5 = 8
Total clothing article = 46
how many were clean
Number of clean clothes = ratio of clean clothes / total ratio × total clothing article
= 3/8 × 46
= 0.375 × 46
= 17.25

The coordinates for three points of a rectangle are (2, 6) (2, 9) and (8, 6). What is the coordinate for the fourth point in the rectangle? The coordinates for the fourth point in the rectangle is

[tex]C = (8,6)[/tex]
Required
Determine the 4th point
The coordinate point of a horizontal or a vertical rectangle is given as:
(x1,y1), (x2,y2), (x3,y3), (x4,y4)
Where:
[tex]x_1 = x_2[/tex] [tex]x_3 = x_4[/tex] [tex]y_1 = y_3[/tex] [tex]y_2 = y_4[/tex]
So, we have:
[tex]A = (2,6)[/tex] --- [tex](x_1.y_1)[/tex]
[tex]B = (2,9)[/tex] ---- [tex](x_2.y_2)[/tex]
[tex]C = (8,6)[/tex] ---- [tex](x_3,y_3)[/tex]
Using the above equations:
[tex]x_3 = x_4[/tex][tex]=8[/tex]
[tex]y_2 = y_4[/tex] [tex]= 9[/tex]
Hence, the coordinate of the 4th point is:
[tex](x_4,y_4) = (8,9)[/tex]

What is the Pythagorean theorem?In the Pythagorean theorem, the sum of the squares of the sides of a right-angled triangle is equal to the square of the longest side i.e, the hypotenuse of the triangle.
z² = x² + y²
The given triangle is a right-angled triangle. This means that we can use the Pythagorean theorem.
∴ y² + 12² = 13²
⇒ y² + 144 = 169
⇒ y² = 169-144
⇒ y² = 25
⇒ y = 5
Therefore, we have solved for the value of y and found that y = 5. The correct answer is option C.
