Answer:

13.37 = BC

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = opp / hyp

cos 27 = BC / 15

15 cos 27 = BC

13.36509 = BC

Rounding to the nearest hundredth

13.37 = BC

Answer:

The 99% confidence interval for the true population proportion of adults with children is (0.6367, 0.7433).

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 z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

In a sample of 500 adults, 345 had children.

This means that [tex]n = 500, \pi = \frac{345}{500} = 0.69[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.69 - 2.575\sqrt{\frac{0.69*0.31}{500}} = 0.6367[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.69 + 2.575\sqrt{\frac{0.69*0.31}{500}} = 0.7433[/tex]

The 99% confidence interval for the true population proportion of adults with children is (0.6367, 0.7433).

Step-by-step explanation:

you have to substitute the function g(x) where there's x in the function f(x)

gf(x)=2(x213)-4

if that's x two thirteen then you can multiply the 2 outside the brackets by it

giving you a final answer of

gf(x)=426x-4

Solution :

Let the probability laser works = p

The probability that the system works = [tex]$P(\text{all three component works}) = p^3 $[/tex]

                                                                                                                   = 0.99

Therefore, p = 0.9967

Now for the above probability critical z = -2.72

Hence, the mean life is equal to = [tex]10,000 + 2.72 \times 600[/tex]

                                                     = [tex]10,000+1632[/tex]

                                                     [tex]=11,632[/tex]

The least possible degree of polynomial is 2

Answer:

X=1

f(x)=16^1

=16

X=2

f(x)=16^2

256

X=3

f(x)=16^3

=4096

X=4

f(x)=16^4

=65536

Here are four different ways to rewrite the function f(x) = 16^x, using a different base for each case:

Using base 2:

f(x) = (2^4)^x = 2^(4x)

Using base 3:

f(x) = (3^2)^x = 3^(2x)

Using base 10:

f(x) = (10^(log10(16)))^x = 10^(log10(16) * x)

Using base e (natural logarithm):

f(x) = (e^(ln(16)))^x = e^(ln(16) * x)

In these rewritten forms, the exponentiation of the base is expressed as a simpler expression.

This involves the new base, which helps to illustrate the relationship between the original function and the different bases used.

Answer:

[tex]Fair = 63.4\%[/tex]

[tex]Too\ Long = 29.7\%[/tex]

[tex]No\ Opinion =6.9\%[/tex]

Step-by-step explanation:

Given

[tex]Total=505[/tex] --- customers

[tex]Fair = 320[/tex]

[tex]Too\ Long = 150[/tex]

Required

Complete the table

To complete the table, we simply divide each value by the total number of customers.

So, we have:

[tex]Fair = 320[/tex]

[tex]Fair = \frac{320}{505}[/tex]

[tex]Fair = 0.634[/tex]

Express as percentage

[tex]Fair = 0.634*100\%[/tex]

[tex]Fair = 63.4\%[/tex]

[tex]Too\ Long = 150[/tex]

[tex]Too\ Long = \frac{150}{505}[/tex]

[tex]Too\ Long = 0.297[/tex]

Express as percentage

[tex]Too\ Long = 0.297*100\%[/tex]

[tex]Too\ Long = 29.7\%[/tex]

For the last set, the percentage is calculated using:

[tex]No\ Opinion + Fair + Too\ Long = 100\%[/tex]

So, we have:

[tex]No\ Opinion + 63.4\% + 29.7\% = 100\%[/tex]

[tex]No\ Opinion + 93.1\% = 100\%[/tex]

Collect like terms

[tex]No\ Opinion =- 93.1\% + 100\%[/tex]

[tex]No\ Opinion =6.9\%[/tex]

If f(x) = 7/(1 + x), then

f (2) = 7/3

f '(x) = -7/(x + 1)²   ==>   f ' (2) = -7/9

f ''(x) = 14/(x + 1)³   ==>   f '' (2) = 14/27

f '''(x) = -42/(x + 1)⁴   ==>   f ''' (2) = -14/27

Then the Taylor series of f(x) about a = 2 is

7/3 + 1/1! (-7/9) (x - 2) + 1/2! (14/27) (x - 2)² + 1/3! (-14/27) (x - 2)³

= 7/3 - 7/9 (x - 2) + 7/27 (x - 2)² - 7/81 (x - 2)³

Answer:

f^(-1)(x)=(x-4)^(1/3)+10

Step-by-step explanation:

So to find the inverse we need to first solve the equation y=(x-10)^3+4 for x.

Subtract 4 on both sides:

y-4=(x-10)^3

Cube root (or raise both sides to 1/3 power):

(y-4)^(1/3)=x-10

Add x on both sides:

(y-4)^(1/3)+10=x

Swap x and y:

(x-4)^(1/3)+10=y

Symmetric property of equality:

y=(x-4)^(1/3)+10

So f^(-1)(x)=(x-4)^(1/3)+10.

Answer:

Assuming you meant three jacks:

1 in 5525 or else 1/5525.

Step-by-step explanation:

You start with a full deck of 52 and 4 jacks. After each draw, you reduce both the jacks and total deck by one. Your first draw would be 4/52. The next would be 3/51. The final draw would be 2/50. You multiply each fraction together as you need all of them to happen, and that is your odds of drawing 3 jacks in a row without replacement.

Answer:

5 grams = 500 centigrams = 5000 milligrams = 5000000 micrograms

Step-by-step explanation:

So the only correct answer in your choices is the third option, 5000 milligrams.

Given:

u varies directly with the square of p and inversely with d.

To find:

The equation for the given situation.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

If y is inversely proportional to x, then

[tex]y\propto \dfrac{1}{x}[/tex]

It is given that u varies directly with the square of p and inversely with d. So,

[tex]u\propto \dfrac{p^2}{d}[/tex]

It can be written as:

[tex]u=k\dfrac{p^2}{d}[/tex]

Where, k is the constant of proportionality.

Therefore, the required equation is [tex]u=\dfrac{kp^2}{d}[/tex].

Step-by-step explanation:

First, we can see that the angles inside the polygon form a full circle, as it goes fully around. Therefore, the sum of the angles around the center of the circle (such as m < 7) is 360 degrees. Since it is a regular polygon, and the lines are going from the center to its corners, the 6 angles directly surrounding the center are equal.

Each angle is therefore 360/6 = 60 degrees, so m<7 is 60 degrees.

For m<8, we can see that a line bisects one of the 6 angles surrounding the center. Therefore, m<8 is 1/2 of the angle it bisects, which is equal to 360/6 = 60 degrees, and m<8 = 60/2 = 30 degrees

Finally, we can see that there are 6 sides of the polygon. For a polygon with n number of sides, the sum of its interior angles is equal to (n-2) * 180. Here, there are 6 sides, so the sum of this polygon's interior angles is (6-2) * 180 = 4 * 180 = 720. Because this is a regular polygon, each interior angle is the same, and because there are 6 of them, each one is 720/6 = 120 degrees. As shown in the picture, m < 9 is seemingly one-half of an interior angle, as it is bisected by a line from the center to a corner.

Therefore, m <9  = 120 /2 = 60 degrees

The number of bacteria in a culture is increasing according to the law of exponential growth. There are 125 bacteria in the culture after 2 hours and 350 bacteria after 4 hours.

The overall percent increase after 4 hours is 21% if the number of bacteria in a colony increases by 10% every 2 hours option (G) is correct.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

The number of bacteria in a colony increases by 10% every 2 hours.

Let there be 100 bacteria in the starting

In the first 2 hours :

= (100×10%) + 100

= 10 + 100

= 110

Again after 2 hours:

= (110×10%) + 110

= 11 + 110

= 121

= (121 - 100)

= 21

Thus, the overall percent increase after 4 hours is 21% if the number of bacteria in a colony increases by 10% every 2 hours option (G) is correct.
