Answer:
75%
Step-by-step explanation:
List out known probabilities
[tex]\Pr(shirt) = 0.65 = \frac{65}{100} = \frac{13}{20}\\ \Pr(pants) = 0.40 = \frac{30}{100} = \frac{6}{20}\\\Pr(shirt \cap pants) = 0.20 = \frac{20}{100}=\frac{1}{5}[/tex]
recall equation
[tex]\Pr(A \cup B)=\Pr(A)+\Pr(B)-\Pr(A \cap B)[/tex]
Plug in values
[tex]\Pr(shirt \cup pants)=\frac{13}{20}+\frac{6}{20}-\frac{1}{5}\\\\therefore \Pr(shirt \cup pants) = \frac{15}{20} =\frac{3}{4} = 75\%[/tex]

Step-by-step explanation:
(2.3x10^5) + (3.6x10^6)
Answer:
3.83 * 10^6
Step-by-step explanation:
When adding exponents, both the exponents and the bases should be the same. In this scenario, the bases are the same but not the exponents. What we should do is to decrease or increase one of the exponents and shift the decimal point over in one of the numbers to either left or right. I like to think of decrease, increase, and shifts as inward shifts and outward shifts when dealing with exponents in scenarios like this one. When I increase an exponet by an amount of times, the decimal point shifts left by the same amount of times. That's an outward shift. When the exponet decreases by an amount of times, the decimal point shifts right by the same amount of times. That's an in ward shift. There are two ways that we can simplify this scenario.
Way One:
(2.3 * 10^5) + (3.6 * 10^6)
(1) Raise the exponent 5 to 6 and move the decimal point in 2.3 to the left once. Now the bases and exponents are equal.
(0.23 * 10^6) + (3.6 * 10^6)
(2) Now add 0.23 and 3.6 then keep 10^6 for your exponential scenario.
3.83 * 10^6
(3) Check to make sure that there is only one number before the decimal. (in this case there is just one number before the decimal)
Final Answer: 3.83 * 10^6
Way Two:
(2.3 * 10^5) + (3.6 * 10^6)
(1) Decrease the exponent 6 to 5 and move the decimal point in 3.6 to the right once. Now the bases and exponents are equal.
(2.3 * 10^5) + (36 * 10^5)
(2) Now add 2.3 and 36 then keep 10^5 for your exponential scenario.
38.3 * 10^5
(3) Check to make sure that there is only one number before the decimal. (in this case there are two numbers before the decimal point; more steps!)
Not Yet Complete: 38.3 * 10^5
(4) Move the decimal point over until there is only one number before the decimal point and raise the exponent 5 to 6. (use the outward shift process!)
3.83 * 10^6
(5) Check for any flaws in your answers. (none left! we are done!)
Final Answer: 3.83 * 10^6
Overall, whatever way you choose to do this, you will get the same answer. I hope this helps and let me know if I am wrong! :D

Need help finding constant rate of change!
Answer:
[tex]m = \frac{4}{7}\\[/tex]
Step-by-step explanation:
Given
The attached graph
Required
The constant rate of change (m)
This is calculated as:
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
From the graph, we have:
[tex](x_1,y_1) = (3,4)[/tex]
[tex](x_2,y_2) = (10,8)[/tex]

[tex]m = \frac{8-4}{10 - 3}[/tex]
[tex]m = \frac{4}{7}\\[/tex]
At the beginning of a basketball season the Panthers won40 games out of 17 games at this rate how many games will they win in a normal 120 game season
Answer:
51
Step-by-step explanation:
The problem states "the Panthers won 40 games out of 17 games"
It is impossible to win more games than the number of games.
Perhaps the problem should state "the Panthers won 17 games out of 40 games"
If this is correct, then we can answer the question with a proportion.
17 wins is to 40 games as x wins is to 120 games
17/40 = x/120
40 * x = 17 * 120
Divide both sides by 40.
x = 17 * 3
x = 51
Answer: 51

Step-by-step explanation:
8. Dates prior to 1 Jan 1788 are those in 1787. The three states admitted in 1787 are listed as Delaware, Pennsylvania, New Jersey. It is usually convenient to list elements of a set in lexicographical order:
A = {Delaware, New Jersey, Pennsylvania}

Answer:
https://www.gigacalculator.com/calculators/volume-of-sphere-calculator.php this the link for the marth calculate
find the volume of a sphere. Only a single measurement needs to be known in order to compute the volume of a sphere and that is its diameter. For example, if the diameter is known to be 20 feet, then calculate the volume by using the first formula above to get 4/3 x 3.14159 x (20/2) 3 = 4.1866 x 1000 = 4188.79 ft 3 (cubic feet).

Answer:
1979
91%
Step-by-step explanation:
Given the relation :
P = (318t + 6792) / (1.19t + 107.36)
P = % of household with PC
t = years since 2000
1.) We need to find t, when P = 85%
P = 0.85
0.85 = (318t + 6792) / (1.19t + 107.36)
0.85(1.19t + 107.36) = (318t + 6792)
1.0115t + 91.256 = 318t + 6792
Collect like terms :
1.0115t - 318t = 6792 - 91.256
−316.9885t = 6700.744
t = 6700.744 / - 316.9885
t = - 21.138760
t = - 21 years
2000 - 21 years = 1979
Percentage who had computer in 2014
t = 2014 - 2000 = 14
P = (318(14) + 6792) / (1.19(14)+ 107.36)
P = (4452 + 6792) / (16.66 + 107.36)
P = 11244 / 124.02
P = 90.6627
P = approximately 91%
A=1/2 bh; solve for b
I need help anyone help me with this
Answer:
b=2A/h
Step-by-step explanation:
[tex]A = \frac{1}{2} bh \\ \\ \therefore \: 2 A = bh \\ \\ \therefore \: b = \frac{2 A}{h} [/tex]
Answer:
b = 2A/h
Step-by-step explanation:
To isolate b, you should first "get rid" of the 1/2. The best way to do this to multiply both sides of the equation by 2. The left side becomes 2A, while the right becomes bh (1/2 multiplied by its reciprocal, 2, becomes 1). Next, you have to move the h to the left side, and you could do so by dividing both sides by h. The left side becomes 2A/h, and the right is just b by itself, getting you b = 2A/h.

What is transformation on the graphs?The function provided by the basic function f(x) and the constant
g(x) = f(x - k),
horizontally moving the f(x) k unit coordinates may be drawn.
The shift's direction depends on the value of k. Specifically,
The base graph moves k units to the right if k > 0, and
The base graph moves k units to the left if k < 0.
Given that the parent function is f(x) = IxI.
From the definition,
the transformed function is moved horizontally to 3 units to the right.
So, the function is g(x) = Ix + 3I.
Therefore, g(x) = Ix + 3I.

Answer:
y - 2 = 0
Step-by-step explanation:
find slope first:
(2-2)/(5+1) = 0/6 or 0
now use 'y=mx+b' to find the y-intercept (the 'b'):
2 = 0(5) + b
2 = b
so, in slope-intercept form, the equation is:
y = 2
but, in standard form, the equation is:
