The probability that an event will happen is 5/8 . What is the probability that the event will not happen?
Answer:(please note im not sure)
3/8 (i think).
Step-by-step explanation:
The probability of this not happening in an event is 3/8.
Probability is a measure of the likelihood or chance that a particular event or outcome will occur. It quantifies the uncertainty associated with different possible outcomes in a given situation. In other words, probability helps us understand the likelihood of an event happening.
The probability of not happening of an event is calculated by subtracting the probability of happening of an event.
The probability of not happening of an event is,
P(not) = 1 - P
P(not) = 1 - 5/8
P(not) = 3 /8
Therefore, the probability that the event will not happen is 3/8.

What number is 62% of 250? Round your answer to the nearest hundredth, if necessary.
Answer: 155
Step-by-step explanation: Well percent means over 100 so we can set up an equation for this problem by reading it from left to right.
What number means x, is means equals,
62% is 62/100, of means times 250.
So we have the equation x = 62/100 · 250.
Simplifying on the right side side of the equation, notice that 62/100 reduces to 31/50 so we have x = 31/50 · 250.
Think of the 250 as 250/1.
So we can cross cancel the 250 and 50 to 50 and 1.
So we 31 times 5 over 1 or 155.
So 155 is 62% of 250.

3. Find the area of the triangle.
A. 21.2 in
B. 10.5 in
C. 21 in
D. 42 in
Answer:
C. 21 in² . . . . your answer selection is correct.
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
where b represents the base of the triangle, and h represents the height of the opposite vertex above that base.
The figure shows you that half the base is 3 in and the height is 7 in, so the area is ...
A = (1/2b)h = (3 in)(7 in) = 21 in² . . . . matches choice C

This remains the same on the moon as on Earth. --> MASS
This results from the pull of gravity. --> WEIGHT
This relates to the amount of matter in an object. --> MASS
This will change in space. --> WEIGHT
mass is a SCALAR, weight is a VECTOR
Step-by-step explanation:
In physics:
- The mass of an object is a scalar quantity that gives a measure of the "amount of matter" in an object. It is an intrinsec property of the object, therefore its value does not depend on the location of the object.
- The weight of an object is the force of gravitational attraction exerted on the object. Being a force, it has a magnitude and a direction. Its magnitude is given by
[tex]F=mg[/tex]
where m is the mass of the object and g is the acceleration due to gravity at the location of the object. Therefore, its value depends on the location.
Now we can identify correctly each statement given:
This remains the same on the moon as on Earth. --> MASS
This results from the pull of gravity. --> WEIGHT
This relates to the amount of matter in an object. --> MASS
This will change in space. --> WEIGHT
mass is a SCALAR, weight is a VECTOR

Panchito Pantera has 100 coins(Quarters and dime). He has a totalof $22.How many quarters does he have?? dimes??
There are 20 dimes and 80 quarters
Solution:
Let "d" be the number of dimes
Let "q" be the number of quarters
1 dime = $ 0.10
1 quarter = $ 0.25
Panchito Pantera has 100 coins
Therefore,
number of dimes + number of quarters = 100
d + q = 100 ----------- eqn 1
He has a total of $22. Thus we frame a equation as:
number of dimes x 0.10 + number of quarters x 0.25 = 22
[tex]d \times 0.10 + q \times 0.25 = 22[/tex]
0.1d + 0.25q = 22 --------- eqn 2
Let us solve eqn 1 and eqn 2
From eqn 1,
d = 100 - q ------- eqn 3
Substitute eqn 3 in eqn 2
0.1(100 - q) + 0.25q = 22
10 - 0.1q + 0.25q = 22
0.15q = 22 - 10
0.15q = 12
Divide both sides by 0.15
q = 80
Substitute q = 80 in eqn 3
d = 100 - 80
d = 20
Thus there are 20 dimes and 80 quarters
Next Tuesday, Cordelia is catering a proposal dinner for her brother. If she wants to serve her macaroni and cheese at this dinner for 2, she will use _____ cup(s) of Parmesan cheese. The recipe includes that 1/2 Cups of Parmesan cheese serves 4 people.
Answer: [tex]\frac{1}{4}\ cups[/tex]
Step-by-step explanation:
For this exercise it is important to analize the information given in the exercise.
According to the data provided in the exercise, the recipe says that [tex]\frac{1}{2}\ cups[/tex] of Parmesan serves four people.
The, let be "x" the amount of cups of Parmesan cheese that Cordelia will use for her brother's proposal dinner.
In this case, since the proposal dinner is for two people, you can set up the following proportion:
[tex]\frac{4}{\frac{1}{2}}=\frac{2}{x}[/tex]
Finally, you must solve for "x" in order to find its value, as you can observe below:
[tex]8=\frac{2}{x}\\\\8x=2\\\\x=\frac{2}{8}\\\\x=\frac{1}{4}[/tex]
Therefore, knowing the value of "x", you can determine that Cordelia will use [tex]\frac{1}{4}\ cups[/tex] of Parmesan cheese for the proposal dinner.

11. Which equation would help you find the
1 missing side length in the right triangle shown
A - 122-102=c2
B- 122+ b2= 102
c. 12(2)+ 10(2) = c(2)
D. 122+ 102 = c3
Answer: A-122-102=c2
Step-by-step explanation: This is the answer to the missing side length in the right triangle shown.
Option B: 122 + b^2 = 102^2 is the correct equation to find the missing side length in the right triangle.
The equation that would help you find the missing side length in the right triangle is option B: 122 + b2 = 1022.
In a right triangle, the Pythagorean theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, 122 is the length of one side and 102 is the length of the other side. By rearranging the equation, you can solve for the missing side length, b.
Let's rewrite the equation using the proper square notation:
122 + b2 = 1022
122 + b2 = 10404
b2 = 10404 - 122
b2 = 10282
b = √10282
b ≈ 101.4

Answer: it’s 20
We have, 120% × x = 24
or,
120/100 × x = 24
Multiplying both sides by 100 and dividing both sides by 120,
we have x = 24 × 100/120
x = 20

A right prism has a base that is an equilateral triangle. The height of the prism is equal to the height of the base. If the volume of the prism is 81, what are the lengths of the sides of the base?
Length of side of base is 5.45
Step-by-step explanation:
Step 1: Volume of a right prism = Area of the base × Height = 1/2 × base × height of base × height of prismHere, since the base is an equilateral triangle and it is given that height of the prism is equal to that of the base, measures of base and height are equal.
⇒ Volume = 1/2 × b × h × h (b and h are equal)
⇒ 81 = 1/2 × b³
⇒ b³ = 162
⇒ b = ∛162 = 5.45

A Galapagos cactus finch population increases by half every decade. The number of finches is modeled by the expression
,
where d is the number of decades after the population was measured. Evaluate the expression for d = −2
Given :
The number of finches is modeled by the expression :
⇒ [tex]45\cdot1.5^d[/tex]
where [tex]d[/tex] is the number of decades after the population was measured.
To evaluate the expression for d=-2
Solution:
In order to evaluate the given expression to find the number of finches at [tex]d=-2[/tex], we will plugin [tex]-2[/tex] for [tex]d[/tex] in the expression and simplify it.
Plugging in [tex]d=-2[/tex] in the expression:
⇒ [tex]45\cdot 1.5^{-2}[/tex]
Using negative exponent property. [[tex]a^{-x}=\frac{1}{a^x}[/tex]
⇒ [tex]45\cdot \frac{1}{1.5^2}[/tex]
⇒ [tex]45\cdot \frac{1}{2.25}[/tex]
