Answer:
14
Step-by-step explanation:
According to order of operations (PEMDAS), you should multiply the numbers on the two sides of the addition sign first. So:
-4 x -5 = 20
and
2 x -3 = -6
Then you add those two numbers together:
-6 + 20 = -14

A shipment of 20 DVDs has arrived at a video rental store. Based on past experience, the manager knows that 10% of all new DVDs sent to the store have a visible defect. The manager tells you to begin inspecting the new DVDs one at a time at random until you find the first DVD that has a defect. If 10% of the DVDs have a visible defect in the new shipment, what is the probability that the first DVD that has a defect is the 3rd one that you inspect? (Round your answer to 3 decimal places.)
Answer:
The probability is 0.081
Step-by-step explanation:
Here, we want to calculate the probability that the 3rd inspection will be defective.
What this means is that the first two would
not be defective.
Probability of having a defective DVD = 10% = 10/100 = 0.1
Probability of not having a defective DVD = 1 -0.1 = 0.9
So the probability of third being defective = Probability of first not defective * Probability of second not defective * Probability of third defective
= 0.9 * 0.9 * 0.1 = 0.081

If a desk is $186with a discount of 50% what is the original retail price for the desk
Answer: $372
Step-by-step explanation:
Let the original retail price be 'x'
Therefore, using the give information, we can form the following equation:
50/100x = 186
Now, solve for x
50/100x = 186
1/2x = 186
x = 186 * 2
x = 372
The original retail price is $372.
Check:
50/100(372) = 186
1/2(372) = 186
186 = 186

Multiply: (x – 4)(x + 5)
(a) x2 + 5x - 20,
(b) x2 - 4x - 20,
(c) x2 - x - 20,
(d) x2 + x - 20.
Answer:
D. x2 + x - 20.
Step-by-step explanation:
(x – 4)(x + 5).
= x(x + 5) -4(x + 5).
= x2 + 5x – 4x – 20.
= x2 + x - 20.

Answer:
[tex]x^3y^5[/tex]
Step-by-step explanation:
[tex]\frac{(x^3y^2)^2(xy^2)}{x^4y} = \frac{(x^6y^4)(xy^2)}{x^4y}=\frac{x^7y^6}{x^4y} =x^3y^5[/tex]
Here , the general rules followed are :-
i) [tex]x^m * x^n =x^m^+^n[/tex]
ii) [tex](x^my^n)^z = (x^m^z)(y^n^z)[/tex]
iii) [tex]\frac{x^my^n} {x^ay^b} = (x^m^-^a)(y^n^-^b)[/tex]

solve for y: 3y=35 pls help
Step-by-step explanation:
Because this is a multiplication equation, and we need to find one of the factors, we divide.
So 35/3=y
35/3=11.6666667
or 11.67/11.7

Which phrase best describes f(x), graphed on the coordinate plane below? On a coordinate plane, a curve goes through two cycles. The first part of the curve approaches x = negative 6, has a maximum at (negative 4, 3), and has a minimum at (negative 2, negative 2). The second part of the curve has a maximum at (1.5, 2.5), has a minimum at (4, negative 3), and approaches x = 6. f(x) is an odd function. f(x) is an even function. f(x) is both odd and even. f(x) is neither odd nor even.
Answer:
It's an odd function.
Step-by-step explanation:
Answer:
a. f(x) is an odd function.

Find a counterexample to show that we don't always have equality.
Answer:
Hello your question is incomplete below is the complete question
Let R be a relation from A to B and S a relation from B to C.
(a) Prove that . [tex]Dom(S \circ R) \subseteq Dom(R)[/tex]
(b) Find a counterexample to show that we don’t always have equality.
answer : (b) Dom ( S o R ) = [ 1 ] and Dom ( R ) = [ 1, ∝ ]
hence: Dom ( S o R ) ≠ Dom ( R )
Step-by-step explanation:
Note : R ⊆ A * B and S ⊆ B * C
A) To prove that [tex]Dom(S \circ R) \subseteq Dom(R)[/tex]
we take note that : S o R ⊆ A x C
ATTACHED BELOW IS THE REMAINING PART OF THE SOLUTION
B) A counterexample to show that we don't always have equality
attached below is a assumptions and solution on how we arrived at the value below
Dom ( S o R ) = [ 1 ] and Dom ( R ) = [ 1, ∝ ]
hence: Dom ( S o R ) ≠ Dom ( R )
A student makes a number of measurements of electrical current in the circuit. The average of the measurements is 12.33 mA. The standard deviation of the sample is 0.14 mA. How should this measurement be written to the correct number of significant figures with error range to show a 95% confidence
Answer:
The way to represent this it is
[tex] 12.33 - \frac{0.27}{\sqrt{n} } < \mu < 12.33 + \frac{0.27}{\sqrt{n} } [/tex]
Step-by-step explanation:
From the question we are told that
The sample mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically represented as
[tex]\alpha = (100-95)[/tex]
[tex]\alpha = 0.05[/tex]
The critical value for [tex]\frac{\alpha }{2}[/tex] is obtained from the normal distribution table that value is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Now the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }[/tex]
[tex]E = \frac{0.27}{\sqrt{n} }[/tex]
Now the error range to show a 95% confidence is mathematically represented as
[tex]\= x - E < \mu < \= x + E[/tex]
[tex] 12.33 - \frac{0.27}{\sqrt{n} } < \mu < 12.33 + \frac{0.27}{\sqrt{n} } [/tex]
Here notice that the significant figure is keep to three to match the significant figure of the given values

Answer: 5-10x

Please help or i am grounded
Answer:
[tex]x=140[/tex]
Step-by-step explanation:
Do not get grounded.
An angle at a point is 360°.
So, [tex]x+120+70+30=360[/tex]
[tex]x+220=360[/tex]
[tex]x=140[/tex]
Remember this All the angles around a point when added gives a 360° !
Thus,
30+ X +70+120 = 360
=> X + 220 = 360
=> X = 140°Some movies are profitable and others are not . Understandably , the movie industry would like to know what makes a movie successful . Data from 728 first-run movies released in 2011 suggest that longer movies actually make less profit. Identify the sample .

The first term of an arithmetic sequence is 2 and the fourth term is 11
Answer:
The sequence has common difference 3, and its general nth term can be written as:
[tex]a_n=3\,n-1[/tex]
Step-by-step explanation:
In order to define the sequence, we recall the formula for the nth term of an arithmetic sequence as:
[tex]a_n=a_1+(n-1)\,d[/tex]
where "d" is the common difference for the sequence (our unknown in this case), and the nth term is our fourth term (n = 4) which equals 11, and the first term is 2:
[tex]a_n=a_1+(n-1)\,d\\11=2+(4-1)\,d\\9=3\,d\\d=9/3\\d=3[/tex]
Therefore our sequence has common difference 3, and its general nth term can be written as:
[tex]a_n=2+(n-1)3\\a_n=3\,n-1[/tex]
choose the correct math expression for :36 minus the quotient of a and 4
