Answer:

25

Step-by-step explanation:

Using the Pythagorean theorem, we need to calculate

15^2+20^2=x^2, which simplifies to:

225+400=x^2,

625=x^2

and since 25^2 equals 625, the answer is AC=25

Step-by-step explanation:

Let's take the given equation

[tex]\frac{7}{14}-\frac{3}{14}[/tex]

Let's also remember the bottom number (denominator) does not change or go away ever!

So we will subtract the top numbers (numerator) and we will get

Suppose we want to formulate a 95% confidence interval for the population proportion and we would like our margin of error to be not greater than 0.04. We have no history with this characteristic, so we have no idea as to what the proportion might be. Conservatively, what is the minimum sample size we should anticipate using? (NOTE: Round up to the nearest whole number)

Answers

Answer:

The minimum sample size we should anticipate using is 601.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

We have no history with this characteristic, so we have no idea as to what the proportion might be.

This means that we use [tex]\pi = 0.5[/tex], which is when the largest sample size will be needed.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

What is the minimum sample size we should anticipate using?

This is n for which M = 0.04. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.04 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.04\sqrt{n} = 1.96*0.5[/tex]

[tex]\sqrt{n} = \frac{1.96*0.5}{0.04}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.04})^2[/tex]

[tex]n = 600.25[/tex]

Rounding up, 601

The minimum sample size we should anticipate using is 601.

Identify the vertex of the graph. Tell whether it is a minimum or a maximum.

Answers

Answer:

Vertex = (-1, 2)

Maximum

Step-by-step explanation:

The middle point of the graph is at x coordinate -1 and the point is at the top while the graph slopes down so it is a maximum point and not a minimum point.

which of the following is not a function? ANSWER FAST PLEASE!!!

Answers

Answer:

D. cannot be an f(x)=y function.

Step-by-step explanation:

An f(x) = y function has to have a specific property - there can be only one value for the same x - and the value has to be the same every time.

D. gives us all xs equal to 9, but with different ys - hence it cannot be an f(x) = y function (it could be an f(y) = x function though, but I assume that's not "allowed" under the problem statement).

B has two equal xs, but both times y=0, so it doesn't make it an invalid function.

Patty purchased rose bushes and geraniums for her yard. Patty spent $206 on 14
rose bushes and 12 geraniums. The price of a geranium is $5 less than twice the
cost of a rose bush. What is the cost of one rose bush?

Answers

9514 1404 393

Answer:

  $7

Step-by-step explanation:

Let r and g represent the costs of a rose bush and a geranium, respectively. The given relations are ...

  14r +12g = 206

  g = 2r -5

Using the second equation to substitute for g in the first equation, we have ...

  14r +12(2r -5) = 206

  38r -60 = 206

  38r = 266

  r = 266/38 = 7

The cost of one rose bush is $7.

Answer:

x = 17

Step-by-step explanation:

area = L x W

45 = (x-2)(x-14)

45 = x² - 14x - 2x + 28

simplify:

x² -16x - 17 = 0

(x + 1)(x -17 ) = 0

x = -1    not applicable

x = 17

Proof:

(17-2)(17-14) = 45

15 x 3 = 45

45 = 45
