For something to be a function, an input (x value) can only have ONE output (y value)

For example:

(2 ,4)

(2, 5) This is not a function because the input has multiple outputs.

So your answer is the 1st option

How can I solve this system of equation with substitution 2a+2x=18 and a+3x=17

3241004551 [841]

First solve for one variable
solve for a in second eqatn

minus 3x both sides
a=17-3x
sub 17-3x for a in first equaiton
2(17-3x)+2x=18
34-6x+2x=18
34-4x=18
minus 34 both sides
-4x=-16
divide both sides by -4
x=4
sub back
a=17-3x
a=17-3(4)
a=17-12
a=5

a is 5
x=4

WORK SECTION (without thoughts)
2a+2x=18 to a+x=9
a+3x=17

a=17-3x
(17-3x)+x=9
17-2x=9
-2x=-8
x=4

a=17-3(4)
a=17-12
a=5

x=4
a=5

Determine whether the statement describes a descriptive or inferential statistic. A recent poll of 3436 luxury car owners in Mic

Reil [10]

Answer:

The statement describes an inferential statistic.

Step-by-step explanation:

The results are being generalized in this vase for the average price of a luxury car in the U.S. by surveying around 3436 luxury car owners.

In inferential statistic, we take the data from the given sample and then we make generalizations about the population.

Determine all critical points the the function:

romanna [79]

$\bf y=x^2-32\sqrt{x}\implies \cfrac{dy}{dx}=2x-32\cdot \cfrac{1}{2}x^{-\frac{1}{2}}\implies \cfrac{dy}{dx}=2x-\cfrac{32}{2\sqrt{x}}
\\\\\\
\cfrac{dy}{dx}=2x-\cfrac{16}{\sqrt{x}}\implies \cfrac{dy}{dx}=\cfrac{2\sqrt{x^3}-16}{\sqrt{x}}\\\\
-----------------------------\\\\$

$\bf 0=\cfrac{2\sqrt{x^3}-16}{\sqrt{x}}\implies 0=2\sqrt{x^3}-16\implies 16=2\sqrt{x^3}
\\\\\\
8=\sqrt{x^3}\implies 2^3=\sqrt{x^3}\implies (2^3)^2=x^3\implies (2^6)^{\frac{1}{3}}=x
\\\\\\
2^{\frac{2}{1}}=x\implies \boxed{4=x}\\\\
-----------------------------\\\\
\textit{the other critical point at }\sqrt{x}=0\implies \boxed{x=0}$

In an effort to cut costs and improve profits, any US companies have been turning to outsourcing. In fact, according to Purchasi

tangare [24]

Answer:

Step-by-step explanation:

This is a binomial probability distribution because there re only 2 possible outcomes. It is either a surveyed company outsourced some part of their manufacturing process in the past two to three years. The probability of success, p would be that a randomly selected company x, outsourced some part of their manufacturing process in the past two to three years. From the information given, p = 54/100 = 0.54

Number of success, x = 338

Number of samples, n = 555

We want to determine the probability that 338 or more companies outsourced some part of their manufacturing process in the past two or three years which is expressed as

P(x ≥ 338)

From the binomial probability calculator,

P(x ≥ 338) = 0.0006

The percentage is 0.0006 × 100 = 0.06%
