If you are given the hypotenuse and an adjacent
side, which trig function should you use?

Answer:

15 days.

Step-by-step explanation:

1 person : 4 bird houses : 3 days

1 person : 20 bird houses : ? days

from 4 bird houses to 20 bird houses, you multiply by 5.

this means you also have to multiply the days by 5

3*5=15

Jared will have to work for 15 days to make 20 bird houses.

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

  arc = 2πr × [tex]\frac{60}{360}[/tex]

        = 2π × 18 × [tex]\frac{1}{6}[/tex]

        = 36π × [tex]\frac{1}{6}[/tex]

        = 6π ≈ 18.8 cm ( to 1 dec. place )

It is none of the above. The actual answer is 215

Step-by-step explanation:

8.6*50/2=215

Answer:

none of these

Step-by-step explanation:

on map 8.6 cm

scale 2cm: 50mi.

on reality if you divide the 8.5 cm into 2 cm portions and for each you have 50 mi. then you get the result

(8.6 /2)*50 = 215 mi.

Answer:

The number is - 9.

Step-by-step explanation:

(y ÷ 9) - 1 = - 2

(y ÷ 9) - 1 + 1 = - 2 + 1

y ÷ 9 = - 1

y ÷ 9 × 9 = - 1 × 9

y = - 9

Answer:

y = 8x - 64

Step-by-step explanation:

Start with y = mx + b, the slope-intercept equation.  Replace m with 8, x with 7 and y with -8:

-8 = 8(7) + b, or

-8 - 56 + b, or

b = -64

Then the desired equation is

y = 8x - 64

Answer:

+ or - 0.044

Step-by-step explanation:

The margin of error is 0.044.

A Margin of Error is defined as the results will vary from the actual population value by how many percentage points, as indicated by the margin of error.

The margin of error using this formula, where z is the critical value.

[tex]ME = z\sqrt{\dfrac{T(1 - t)}{n} }[/tex]

To determine a margin of error for a sample proportion,

Where n is the sample size and is the sample proportion, these assumptions must be true.

n t ≥ 10

n(1 - t) ≥ 10

Write the proportion of lead to significant as a decimal number first,

42%

= 0.42

Now substitute the sample proportion and the sample size, 479, the assumptions are inserted into the equations to see if they are satisfied.

⇒(479X0.42) 201.18

⇒ (479)(1 − 0.42)

⇒  277.82

Both values are greater than 10, so the assumptions are satisfied, and the margin of error can be calculated.

Determine the margin of error using this formula, where z is the critical value.

[tex]ME = z\sqrt{\dfrac{T(1 - t)}{n} }[/tex]

For a 95% confidence level, z = 1.96.

Substitute the values of z, n, and T into the formula for margin of error and evaluate.

[tex]ME = 1.96\sqrt{\dfrac{0.42(1 - (10.42)}{479} }[/tex]

ME ≈ 0.044

Hence, the margin of error is 0.044.

The true statement about the histogram are

The dataset is given as:

5.5, 6, 7, 10, 7.5, 8, 9.5, 9, 8.5, 8, 7, 7.5, 6, 6.5, 5.5

Using a statistical calculator, we have the following summary:

Mean = 7.43

Median = 7.5

Notice that the median and the mean are approximately equal

i.e. 7.43 ≈ 7.5

When the mean and the median are equal, the histogram would have an approximately normal curve

Also, when the dataset is sorted, we have:

5.5, 5.5, 6, 6, 6.5, 7, 7, 7.5, 7.5, 8, 8, 8.5, 9, 9.5, 10

Notice that there are more data elements between 6 and 9.

Hence, the true statement about the histogram are (a), (d) and (e)

Answer:

A.

Step-by-step explanation:

It was trick question because they all are opinionated, but the first one should be an easy yes or no question. However, if you do not like the president then you would say no because of bias. The rest are supposed to be "biased" because they are asking what you prefer.

"Should the President of the United States serve a six-year term?" is question is biased

Survey bias is a "systematic error introduced into sampling or testing by selecting or encouraging one outcome or answer over others." Due to this "encouragement" for a particular result, surveys may be biassed and only provide one type of consumer perspective.

For first, It presumes that the responder supports the idea that the President should hold office for a six-year term, which may not apply to all respondents.

However, out of bias, you would say "no" if you didn't like the president. The others are supposedly "biassed" since they inquire about your preferences.

Thus, the biased question is Should the President of the United States serve a six-year term?.

The general equation of the sinusoid is  [tex]f(x)=sinx[/tex]

"A sine wave or sinusoidal is a continuous or mathematical curve which is used to describe a smooth periodic oscillation."

We know,

A Sinusoidal function is a function that can be modelled using a sine wave.

The sine graph repeats itself after a period of 2π, which shows the function is periodic with a period of 2π.

f (x) = sin x and f (x) = cos x are similar apart from a phase shift, both functions are sinusoidal.

f (x) = tan x is a trigonometric function, but its graph is completely different.

The graph of a sinusoidal function is a smooth periodic graph.

The graph is continuous all over the x-axis and also it repeats itself after every fixed interval.

∵ A phase shift is the only difference between sine and cosine, any sinusoidal function that can be modelled using sine can also be modelled using cosine.

The general sinusoidal function is  [tex]f(x)=[/tex]±[tex]a.sin(b(x+c))+d[/tex]

Where as,

± controls the reflection across the x - axis, coefficient a controls the amplitude , constant d controls the vertical shift, coefficient b controls the horizontal stretch.

∴ The general equation of the sinusoid is  [tex]f(x)=sin x[/tex]

Do 15^2 +10^2=c^2 than put answer Into \sqrt()

Step-by-step explanation:

Step-by-step explanation:

Ok, so the pythagorean theorem is  a^2 + b^2  = c^

where c is the hypotenuse and b and a are the the other 2 sides

9) 10^2 + b^2 = 15^2

100 + b = 225

-100       -100

b^2 = 125

sqrt of 125 = 5

b = 5

10) 2^2 + 5^2 = C^2

4 + 25 = c^2

sqrt of 29 = c

c = [tex]\sqrt{29\\}[/tex]
