Q.1. The potter at a pottery store makes two sizes of vases. The larger size takes six hours to make, and the smaller size takes 1.5 hours to make. The potter works 30 hours a week. She needs to make at least six total vases a week, including at least two of each size. Give one example of how many of each type of vase the potter can make.
Answers
Answer:
Step-by-step explanation:
Let x and y be the large (x) and small (y) vases the potter makes in one week.
We are told that the large and small vases require 6 hours for each large(x) and 1.5 hours for each small (y) vase. The combination of large and small vases made in one week thus requires a total time of:
6x + 1.5y = total hours/week
We are told that the potter works 30 hours per week, so:
6x + 1.5y = 30 hours
We also learn that she needs to make at least 6 vases in a week, so:
x + y => 6
Plot the two equations:
6x + 1.5y = 30, and
x + y => 6
This will produce the attached grap, Vases1. The inequality appears as the shaded area in the upper area. Any point in the shaded area satisfies the inequality of x + y => 6. The x and y intercepts are at (0,6) and (6,0), representing either all large (x) or small vases (y).
The lines intersect at (4.67,1.33). This represents a fictional combination of 4.67 large and 1.33 small vases. This results in 6 vases (4.67 + 1.33) that require a total of 30 hours to make (6*4.67 + 1.5*1.33) = 30 hours. If you want to select whole number answers, they appear at (0,6), (2,4), (4,2), and (6,0). (x,y or large,small). All combinations result in 6 vases, but eould require less than the 30 hours of time available. Any whole number combination in the area below the line 6x + 1.5y = 30, but above the line x+y =>6 are valid, such as (4,4). This area is shown in Vases2. The valid area for making choices has the darkest shade, where the two inequalities are both satisfied.

Events A and B are overlapping.

Find P(A or B).

Answers
5/11 is the final answer.
P(A) = 4/11P(B) = 3/11When events are overlapping
formula: P(A or B) = P(A) + P(B) - P(A and B)
=======
P(A or B) = 4/11 + 3/11 - 2/11
P(A or B) = 7/11 - 2/11
P(A or B) = 5/11
Answer:
5/11
Step-by-step explanation:
Given:
P(A) = 4/11P(B) = 3/11P(A ∩ B) = 2/11We can construct a Venn diagram to help answer this question (see attached).
Place 2/11 in the overlapping part. Then calculate the remaining probabilities:
P(A) - P(A ∩ B) = 4/11 - 2/11 = 2/11
P(B) - P(A ∩ B) = 3/11 - 2/11 = 1/11
P(A' ∩ B') = 1 - 5/11 = 6/11
So P(A ∪ B) = 2/11 + 2/11 + 1/11 = 5/11

Step-by-step explanation:
1st step: 1/4 divided by 8, which is 1/4 divided by 8/1
Then for the 2nd step, you have to find the reciprocal of the 2nd fraction, so you just reverse it
2nd step: 1/4 X 1/8
3rd step. 1X1/4X8 = 1/32
You can also think of it like this. He started with 4 pieces. Each piece was then divided into 8 parts. So 8X4=32 is the total number of pieces. He's only eating 1 of those, so he's only eating 1/32

Step-by-step explanation:
Each time when we we cut the ribbon for making a ribbon, the length will be reduced. So, repeated subtraction is division.
To find the number of bracelets, divide the total length of the ribbon by the length required for making a bracelet.
Fraction division:
Use KCF method
Step1: Keep the first fraction
Step2: Change division to multiplication
Step3: Flip the second fraction
Number of bracelets = total length ÷ length required for making a bracelet.
[tex]= 5\dfrac{1}{3} \div \dfrac{2}{3}\\\\= \dfrac{16}{3} \div \dfrac{2}{3}\\\\= \dfrac{16}{3}*\dfrac{3}{2}\\\\= 8[/tex]

Step-by-step explanation:
Use PEDMAS
[3 *2⁵ + 13*(-2) ] + 7[8-(4-9) ] = [3*2⁵ + 13*(-2)] +7[ 8 - (-5) ]
{calulate the inner most parentesis (4- 9 = -5)}
= [3*32 + 13*(-2) ] + 7* [ 8+5]
{Find the exponent 2⁵ = 32}
= [ 96 + (-26) ] + 7* 13
{Here 3 & 32 aree multiplied & 13 and (-2) are multiplied and 8 is added to 5}
= 70 + 91

What is addition of algebraic expression?Addition of Algebraic Expressions is the process of collecting like terms and adding them. Identify and add the coefficients of like terms and sum them to find the final expression of given problems.
The given algebraic expressions are 7x/x²-4 and 2/x+2
Here, 7x/x²-4 can be written as 7x/(x+2)(x-2)
Now, 7x/x²-4 + 2/x+2
= 7x/(x+2)(x-2) + 2/x+2
= (7x+2(x-2))/(x+2)(x-2)
= (7x+2x-4)/(x²-4)
= (9x-4)/(x²-4)

How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
For this case, we're given the rule y = x + 8
The table given is:
x y
2

Evaluating 'y' for the given values of x from the table according to the rule 'y = x + 8', we get:
Case 1: x = 2y = x + 8
y = 2 + 8
y =10
Case 2: x = 0y = x + 8
y = 0 + 8
y =8
Case 3: x = 4y = x + 8
y = 4 + 8
y =12
Thus, the completed table would be:
x y
