It is given in the question that

Suppose the supply function for product x is given by

$qxs = - 30 + 2px - 4pz.$

And we have to find how much of product x is produced when px = $600 and pz = $60.

And for that, we have to substitute 600 for px and 60 for pz, and on doing so, we will get

$qxs = -30+2(600)-4(60)
\\
qxs = -30 +1200 -240 = 930$

And that's the required answer .

Given: △PTC m∠T=120°, m∠C=30° PT=4 Find: PC.

DaniilM [7]

The law of sines tells you ...

... PC/sin(T) = PT/sin(C)

Multiplying by sin(T), we get ...

... PC = PT·(sin(T)/sin(C))

... PC = 4·sin(120°)/sin(30°) = 4·(√3/2)/(1/2)

... PC = 4√3 ≈ 6.928

On a coordinate plane, solid circles appear at the following points: (negative 2, negative 5), (negative 1, 3), (1, negative 2),

Answer:

Last option: It is not a function because there are two different y-values for a single x-value.

Step-by-step explanation:

It is necessary to remember that, by definition, a relation is a function if each input value (x-value) has one and only one output value (x-value) .

In this case, the following points:

$(-2, -5), (- 1, 3), (1, -2), (3, 0), (4,- 2), (4, 4)$

You can observe that the input value 4 ( $x=4$ ) has two ouput values. These are:

$y=-2\\\\ y=4$

Therefore, since there are two different y-values for a single x-value, you can conclude that the given graph is not a function.

Some of the steps in Liam solution to 3. 5 (1.25x + 0.5) = 10.5 are shown complete the boxes with reasons for lines 2 and 4 of L

babymother [125]

Answer:

x = 2

Step-by-step explanation:

Given the equation;

3. 5 (1.25x + 0.5) = 10.5

Open the parenthesis

3.5(1.25x) + 3.5(0.5) =10.5

4.375x + 1.75 = 10.5

4.375x + 1.75 -1.75= 10.5-1.75

4.375x = 8.75

Divide both sides by 4.375

4.375x/4.375 = 8.75/4.375

x = 2

Hence the solution to the equation is 2

Assume that you plan to use a significance level of α = 0.05 to test the claim that p1 = p2. Use the given sample sizes and numb

dezoksy [38]

Answer:

The calculated value Z = 3.775 > 1.96 at 0.05 level of significance

Null hypothesis is rejected

The Two Population proportion are not equal

Step-by-step explanation:

Given first sample size n₁ = 677

First sample proportion

$p^{-} _{1} = \frac{x_{1} }{n_{1} } = \frac{172}{677} = 0.254$

Given second sample size n₂ = 3377

second sample proportion

$p^{-} _{2} = \frac{x_{2} }{n_{2} } = \frac{654}{3377} = 0.1936$

Null Hypothesis : H₀ : p₁ = p₂.

Alternative Hypothesis : H₁ : p₁ ≠ p₂.

Test statistic

$Z = \frac{p_{1} ^{-}-p^{-} _{2} }{\sqrt{P Q(\frac{1}{n_{1} } +\frac{1}{n_{2} }) } }$

where

$P = \frac{n_{1} p_{1} + n_{2} p_{2} }{n_{1}+n_{2} } = \frac{677 X 0.254+3377 X 0.1936}{677+3377}$

P = 0.2036

Q = 1 - P = 1 - 0.2036 = 0.7964

$Z = \frac{0.254- 0.1936 }{\sqrt{0.2036 X 0.7964(\frac{1}{677 } +\frac{1}{3377 }) } }$

Z = 3.775

Critical value ∝=0.05

Z- value = 1.96

The calculated value Z = 3.775 > 1.96 at 0.05 level of significance

Null hypothesis is rejected

The Two Population proportion are not equal
