Your teacher is giving away candy from a bag. The bag contains 5 Reese's Peanut
Butter Cups, 4 Snickers, 3 Sour Patch, & 6 Skittles. Find the probability that you and
your friend choose Snickers. Find P(Snickers n Snickers).
Answers
Answer:
P(Snickers n Snickers) = [tex]\frac{2}{51}[/tex]
Step-by-step explanation:
Given
Bag of candy
5 Reese's Peanut Butter Cups,
4 Snickers
3 Sour Patch
6 Skittles
Required
Calculate P(Snickers n Snickers)
To solve this question, it'll be assumed that you and your friend selected snickers at a consecutive time.
First, we need to calculate the total number of candy
Total = 5 + 4 + 3 + 6
Total = 18 candies
P(Snickers n Snickers) means P(Snickers and Snickers);
i.e. the probability of selecting snicker twice
Number of snickers = 4;
So, the probability of you selecting a snicker first is [tex]\frac{4}{18}[/tex]
This is gotten by dividing number of snickers by total candies.
At this point, there are 4 - 1 snickers left and there are 18 - 1 candies left;
So, the probability of your friend selecting a snicker is [tex]\frac{4 - 1}{18 - 1}[/tex].
So, P(Snickers n Snickers) = [tex]\frac{4}{18}[/tex] * [tex]\frac{4 - 1}{18 - 1}[/tex]
P(Snickers n Snickers) = [tex]\frac{4}{18}[/tex] * [tex]\frac{3}{17}[/tex]
P(Snickers n Snickers) = [tex]\frac{2}{9}[/tex] * [tex]\frac{3}{17}[/tex]
P(Snickers n Snickers) = [tex]\frac{2}{3}[/tex] * [tex]\frac{1}{17}[/tex]
P(Snickers n Snickers) = [tex]\frac{2}{51}[/tex]
Hence, the probability of you and your friend choosing snickers is [tex]\frac{2}{51}[/tex]

a plumber works $22 per hour. the hourly rate increases 3% each year. a. write a function the represents the plumbers hourly rate after t years b. what is the plumbers hourly rate after 8 years.
Answers
Answer:
Step-by-step explanation:
Assuming t = two years
3% of $22.00 = .66
step-by-step
3 percent *22.00 =
(3:100)*22.00 =
(3*22.00):100 =
66:100 = 0.66
A) .66x2 = 1.32 + 22.00 = 23.32
after 2 years the plumber will make $23.32 per hour
B) .66x8 = 5.28 = 22.00 = 27.28
after 8 years the plumber will make $27.28 per hour
The required hourly rate for a plumber after 8 years will be $27.86 per hour.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
here,
As mentioned in the question, a plumber works for $22 per hour. the hourly rate increases by 3% each year.
Let y be the hourly rate of the plumber after t years,
[tex]y = 22 [1 + 0.03]^t\\y = 22[1.03]t[/tex]
Put t = 8
[tex]y = 22 [1.03]^8\\y = 27.86[/tex]
Thus, the required hourly rate for a plumber after 8 years will be $27.86 per hour.

If the graph of h is translated vertically upward by 4 units, it becomes the graph of a function g.
Find the expression for g(x).
Answers
Answer:
[tex]g(x)=x^2+1[/tex]
Step-by-step explanation:
The given function is
[tex]h(x)=x^2-3[/tex]
If a function translated vertically upward by p units, then we need to add p in the function value to get the new function.
It is given that if the graph of h is translated vertically upward by 4 units, it becomes the graph of a function g. So,
[tex]g(x)=h(x)+4[/tex]
[tex]g(x)=x^2-3+4[/tex]
On simplification, we get

Therefore, the required function is [tex]g(x)=x^2+1[/tex].

Water makes about 3/4 of a person’s weight. If a student weighs 100 lbs., how much of his weigh is water?
Answers
Answer:
75 pounds
Step-by-step explanation:
To solve this problem, find 3/4 of 100.
To multiply fractions, multiply the numerators by each other and the denominators by each other.
3/4 * 100/1
Evaluating 3*100 and 4*1, the fraction becomes 300/4.
Now, divide 300 by 4 to get the final answer. 300/4 = 75. Therefore, 75 pounds of the students weight is water.
Answer:
75 lbs
Step-by-step explanation:
3/4 * 100

The probability that a sequence will contain exactly one zero is true in options {B}, {C} and {D}.
We can write the formula for probability as -
P{Event} = (no. of favorable outcomes)/(Total no. of favorable outcomes)
For the sequence {A} -
000, 001, 010, 011, 100, 101, 110, 111
P{one zero} ≠ 7/8
For the sequence {B} -
001, 011, 101, 111
P{one zero} = 7/8
For the sequence {C} -
000, 010, 011, 101, 111
P{one zero} = 2/8
For the sequence {C} -
000, 001, 010, 011, 100, 101, 110, 111

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. the equations that can be solved to get a unique solution. the power of the equation must be in one degree.
First we need to find the slope we will use rise over run to get 2.
The correct equation will replace x with any of the x values in the chart and if we get the same y values as the chart then that equation is correct.
y= 2x-3
If x = 2 and y = 1

Answer:

Step-by-step explanation:
"Variable b is 7 more than variable c" can be expressed mathematically as
b = c + 7
"Variable b is 1 less than variable c" can be expressed mathematically as
b = c - 1

b = c + 7
b = c - 1
best models the relationship between b and c

In ABC, A is a right angle. And B = 45 degrees. What is the length of BC
A) 54ft
B) 17√ 3ft
C) 17√ 2ft
D) 17ft
Answers
Given that this is an isosceles triangle (triangle with two congruent sides) and is 45 degrees on both sides then this would be considered a 45-45-90 triangle
The rule for this type of triangle is that going from a congruent side (for example segment AC) to BC would result in your multiply by the square root of 2.
Multiplying square roots and whole numbers are fairly easy, just combine it like multiply with a variable. Since the rule for a 45-45-90 triangle is to multiply the side length by the square root of 2 to get the hypotenuse then you would multiply 17 by the square root of 2 which will give you answer choice C.
If you encounter a similar problem like this but with the hypotenuse to the side length then you would do the OPPOSITE of multiplying by the square root of 2 (which would be dividing the hypotenuse by the square root of 2).
