Answer:

-6x+4

Step-by-step explanation:

y-intercept is at 4 which is b.

It goes down 6 units as it decreases from 4 to -2.

Since it decreases 6 is negative

therefore -6x+4

Answer:

the monthly payment is $636.02

Step-by-step explanation:

The calculation of the monthly amount deposited i.e. PMT is shown below:

GIven data

NPER = 15 × 12 months = 180

RATE = 5% ÷ 12 = 0.4167%

PV = $0

FV = $170,000

based on the above information

The formula is given below:

= PMT(RATE;NPER;PV;FV;TYPE)

After applying the given formula, the monthly payment is $636.02

Answer:

A sample size of 385 is needed.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

You feel that a reasonable estimate of the standard deviation is 10.0 hours.

This means that [tex]\sigma = 10[/tex]

What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence?

A sample size of n is needed. n is found when M = 1. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]1 = 1.96\frac{10}{\sqrt{n}}[/tex]

[tex]\sqrt{n} = 1.96*10[/tex]

[tex](\sqrt{n})^2 = (1.96*10)^2[/tex]

[tex]n = 384.16[/tex]

Rounding up:

A sample size of 385 is needed.

Answer:

the probability is 0.0378

Step-by-step explanation:

 Given that;

cumulative distribution function: F (x ) = 1 - ( 1 / ( x + 1)³ )

probability the person's reaction time will be between 0.9 and 1.1 seconds will be;

p( 0.9 < x < 0.9 ) = F( 1.1 ) - F( 0.9 )

p( 0.9 < x < 0.9 ) = [1 - ( 1 / ( 1.1 + 1)³ )] - [1 - ( 1 / ( 0.9 + 1)³ )]

= [1 - ( 1 / ( 2.1)³ )] - [1 - ( 1 / ( 1.9)³ )]

= [1 - 0.107979] - [1 - 0.14579]

= 0.8920 - 0.8542

= 0.0378

Therefore, the probability is 0.0378

Answer:

y = [tex]-2^x[/tex]

Step-by-step explanation:

If the equation of a function is in the form of y = h(x)

When the graph of this function is reflected across x-axis,

Transformed function will be,

y = -h(x)

Further reflected across y-axis, then the transformed function will be,

y = -h(-x)

By this rule,

Given equation when reflected across x-axis,

y = [tex]-(\frac{1}{2})^{x}[/tex]

Further reflected across y-axis,

y = [tex]-(\frac{1}{2})^{-x}[/tex]

y = [tex]-(2^{-1})^x[/tex]

y = [tex]-2^x[/tex]

Answer:

No, the sum of the two smaller sides must be greater than the longer side.

In this case this would be just a straight line.

[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]

The given lengths won't form a triangle. The sum of the 2 smaller sides should be greater (not equal too) than the longest side.

so, the longest side her is 12ft

so the smaller sides are 4ft, and 8ft.

the sum of this two sides is 12ft which same as longest side (not greater)...

so it won't form a triangle, here it will just form points on lines.

Answer:

The average value of g is:

[tex]\displaystyle g_{ave}=\frac{1}{6}e^6-\frac{49}{6}\approx 59.071[/tex]

Step-by-step explanation:

The average value of a function is given by the formula:

[tex]\displaystyle f_{ave}=\frac{1}{b-a}\int_a^b f(x)\, dx[/tex]

We want to find the average value of the function:

[tex]g(x)=e^{3x-3}-4x[/tex]

On the interval [1, 3].

So, the average value will be given by:

[tex]g_{ave}=\displaystyle \frac{1}{3-1}\int_1^3 e^{3x-3}-4x\, dx[/tex]

Simplify. We will also split the integral:

[tex]\displaystyle g_{ave}=\frac{1}{2}\left(\int_1^3e^{3x-3}\, dx-\int _1^3 4x\, dx\right)[/tex]

We can use u-substitution for the first integral. Letting u = 3x - 3, we acquire:

[tex]\displaystyle u=3x-3\Rightarrow du = 3\, dx\Rightarrow \frac{1}{3} du=dx[/tex]

We will also change the limits of integration for our first integral. So:

[tex]u(1)=3(1)-3=0\text{ and } u(3)=3(3)-3=6[/tex]

Thus:

[tex]\displaystyle g_{ave}=\frac{1}{2}\left(\frac{1}{3}\int_0^6 e^{u}\, du-\int _1^3 4x\, dx\right)[/tex]

Integrate:

[tex]g_{ave}=\displaystyle \frac{1}{2}\left(\frac{1}{3}e^u\Big|_0^6-2x^2\Big|_1^3\right)[/tex]

Evaluate. So, the average value of g on the interval [1, 3] is:

[tex]\displaystyle g_{ave}=\frac{1}{2}\left(\frac{1}{3}\left[e^6-e^0\right]-\left[2(3)^2-2(1)^2\right]\right)[/tex]

Evaluate:

[tex]\displaystyle\begin{aligned} g_{ave}&=\frac{1}{2}\left(\frac{1}{3}(e^6-1)-16\right)\\&=\frac{1}{2}\left(\frac{1}{3}e^6-\frac{1}{3}-16\right)\\&=\frac{1}{6}e^6-\frac{49}{6}\approx59.071\end{aligned}[/tex]

Hi there!

[tex]\large\boxed{cos(\frac{\theta}{2} )= \frac{3}{\sqrt{7}}}[/tex]

[tex]\large\boxed{tan(\frac{\theta}{2}) = \frac{\sqrt{5}}{3}}[/tex]

Begin by recalling that:

sin(θ) = O/H,  so:

Opposite side = 3√5

Hypotenuse = 7

We can solve for the adjacent sign using the Pythagorean Theorem:

7² = (3√5)² + b²

49 = 45 + b²

b² = 4

b = 2.

Thus, cosθ = 2/ 7

Use the half angle identity to solve for cos(θ/2):

cos(θ/2) = √(1 + cosθ)

Plug in the value of cosθ:

= √(1 + 2/7) = √9/7, or 3 /√7

Thus:

[tex]cos(\frac{\theta}{2}) = \frac{3}{\sqrt{7}}[/tex]

Calculate tan(θ/2) using the same process but with a different formula:

tan(θ/2) = √(1 - cosθ / 1 + cosθ)

Substitute in the value of cosθ:

tan(θ/2) = √(1 - 2/7)/(1 + 2/7)

= √(5/7)/(9/7) = √5/9 = √5/3

17

Answer:

f(-2) = 3(-2)² - 2(-2) + 1 = 17

Step-by-step explanation:

f(x) = 3x² - 2x + 1

f(-2) = 3(-2)² - 2(-2) + 1

= 3 × 4 + 4 + 1

= 12 + 5

f(-2) = 17

Thus, f(-2) = 3(-2)² - 2(-2) + 1 = 17

Answer:

S^2 = sample variance

x_i = the value of the one observation

\bar{x} = the mean value of all observations

n = the number of observations

Step-by-step explanation:

In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. In other words, it measures how far a set of numbers is spread out from their average value.
