Find the diagonal of a television screen 30 inches wide by 35 inches tall.
Round answer to the nearest tenth (if necessary).
Answer:
46.1 in
Step-by-step explanation:
Given data
Width= 30in
Height= 35in
To find the diagonal, we have to use the Pythagoras theorem
z^2= x^2+y^2
z^2= 30^2+ 35^2
z^2= 900+1225
z^2= 2125
z= √2125
z= 46.09
Hence the diagonal of the TV is 46.1 in

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
What is the length of the arc shown in red?
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]

Which survey question is biased?
A. "Should the President of the United States serve a six-year term?"
B. "Which meal-breakfast, lunch, or dinner-is your favorite meal of the day?"
C. “During which month do you prefer to go on vacation?"
D. “Do you prefer white bread or healthy, whole-wheat bread?”
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
What is Survey bias?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?.

What is the equation of the sinusoid?
Will mark brainliest plz help
The general equation of the sinusoid is [tex]f(x)=sinx[/tex]
What is sinusoidal?"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]

(31 points) Wilson County School District consists of 2,548 students. The district decided to conduct a survey regarding their new dress code policy. Wilson County School District surveyed 479 of their students and found that 42% of those surveyed disliked the new dress code policy. What is the margin of error, assuming a 95% confidence level?
Answer:
+ or - 0.044
Step-by-step explanation:
The margin of error is 0.044.
What is a Margin of Error?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.

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

b^2 = 125
sqrt of 125 = 5
b = 5

Which statements are true about a histogram with one-minute increments representing the data? Select three options.
A histogram will show that the mean time is approximately equal to the median time of 7.5 minutes.
The histogram will have a shape that is left-skewed.
The histogram will show that the mean time is greater than the median time of 7.4 minutes.
The shape of the histogram can be approximated with a normal curve.
The histogram will show that most of the data is centered between 6 minutes and 9 minutes.
Answer:
A, D, E
Step-by-step explanation:
GOT IT RIGHT ON EDGE
The true statement about the histogram are
(a) the median and the mean are approximately equal(d) the histogram would have an approximately normal curve(e) there are more data elements between 6 and 9.How to interpret the histogram?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
