please fast answer. to find the height of the pole, a surveyor uses a theodolite. the theodolite is 4 ft tall. the surveyor stands 140 feet away from the base of the pole . then she measures the angle of elevation to the top of the pole to be 44. what is the height of the pole? round to the nearest foot.
Answers
Answer:
C. 139 ft
Step-by-step explanation:
Height of the pole = x + 4 ft
First, find x using trigonometric function.
Reference angle = 44°
Opposite side length = x
Adjacent side length = 140 ft
Apply TOA, which is:
Tan 44 = opp/adj
Tan 44 = x/140
Multiply both sides by 140
140 × Tan 44 = x
135.196428 = x
x ≈ 135 ft
✔️Height of the pole = x + 4 ft = 135 + 4 = 139 ft

Which value is needed to determine a confidence interval for a sample mean?
OA
the margin of error for the proportion
ов.
the population size
OC.
the sample proportion
OD
the standard error of the mean
Answers
Answer:
D. the standard error of the mean
Step-by-step explanation:
trust me i got it right Plato
The value needed to determine a confidence interval for a sample mean is the standard error of the mean option (D) is correct.
What is a confidence interval for population standard deviation?It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.
The formula for finding the confidence interval for population standard deviation as follows:
[tex]\rm s\sqrt{\dfrac{n-1}{\chi^2_{\alpha/2, \ n-1}}} < \sigma < s\sqrt{\dfrac{n-1}{\chi^2_{1-\alpha/2, \ n-1}}}[/tex]
Where s is the standard deviation.
n is the sample size.
[tex]\chi^2_{\alpha/2, \ n-1} and \chi^2_{1-\alpha/2, \ n-1}[/tex] are the constant based on the Chi-Square distribution table:
α is the significance level.
σ is the confidence interval for population standard deviation.
Calculating the confidence interval for population standard deviation:
We know significance level = 1 - confidence level
It is given that:
The value needed to determine a confidence interval for a sample mean is the standard error of the mean.
CI = X + Z(s/√n)
Here CI is the confidence interval
Z is the confidence level
X is the sample mean
Thus, the value needed to determine a confidence interval for a sample mean is the standard error of the mean option (D) is correct.

Complete question :
A business owner wants to know if it will be profitable to open a new coffee shop in a nearby town.In towns where the shop has been successful,the shop name is recognizable to people 53% of the time .He survey random sample of 12 residents of the town. Find the probability that among these 12 surveyed residents, none of them have ever heard of the coffee shop
Answer:
0.000116
Step-by-step explanation:
Using the binomial probability relation :
Probability of success, p = 0.53
1 - p = 0.47
Number surveyed, n = 12
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability that none has heard of the coffee shop :
P(x = 0) = 12C0 * 0.53^0 * 0.47^12
P(x = 0) = 0.000116

Find the area of the shaded area using the given dimensions:
The shaded area is divided up into two triangles, each with a base of 2 cm and a height of 2 cm. Use the following equation to solve for area:
A = 1/2(bh)
A = 1/2(2 · 2)
A = 1/2(4) = 2 cm²
There are two triangles, therefore:
2 × 2 = 4 cm²

because

a=1 b=4 c=-20
a=1 b =4 c = 20
a=1 b=-4 c=0
2x²+6x+5=0
-2x²+x+5 identify the coefficients
Answers
Step-by-step explanation:
The general form of the quadratic equation is :
[tex]ax^2+bx+c[/tex]
The given equation is x²+4x+20=0
On comparing the given equation and the general equation, we find that
a = 1, b = 4 and c = 20
Hence, the correct option is a=1 b =4 c = 20.
If the equation is 2x²+6x+5=0, then
a = 2, b = 6 and c = 5
If the equation is -2x²+x+5
a = -2, b = 1 and c = 5

*domain is the x-value, input, independent

*range is the y-value, output, dependent

Functions are when each input(x) has one and only one output(y)
If you were to graph a function, no points would line up vertically with one another.
This question would not be a function because an input (number 1 in this case) has more than one output (1 AND -4)
