Answer: On a coordinate plane, 4 points are plotted. The points are (1, 375), (2, 225), (3, 135), (4, 81).
Step-by-step explanation:
We have the relation:
f(x + 1) = (3/5)*f(x)
such that the first term is 375
Then:
f(1) = 375.
Using the above relation, we have that:
f(1 + 1) = f(2) = (3/5)*f(1) = (3/5)*375 = 225
Then we have the pair (2, 225)
The next term is:
f(2 + 1) = f(3) = (3/5)*f(2) = (3/5)*225 = 135
Then we have the pair (3, 135)
the next term is:
f(3 + 1) = f(4) = (3/5)*f(3) = (3/5)*135 = 81
Then we have the pair (3, 81)
Then the correct option is the first one; On a coordinate plane, 4 points are plotted. The points are (1, 375), (2, 225), (3, 135), (4, 81).

Answer:
x=4 z=117
Step-by-step explanation:
Answer:
x = 4, z = 117
Step-by-step explanation:
14x + 7 and 63 are vertically opposite angles and are congruent, then
14x + 7 = 63 ( subtract 7 from both sides )
14x = 56 ( divide both sides by 14 )
x = 4
z and 63 are adjacent angles and are supplementary, then
z + 63 =180 ( subtract 63 from both sides )
z = 117

1)Find the angle of elevation of the sun from the ground when a tree that is
14ft tall casts a shadow 16ft long. Round to the nearest degrees
Answer:
[tex]\theta=41.18^{\circ}[/tex]
Step-by-step explanation:
Given that,
The height of the tree, h = 14 ft
The height of the shadow, b = 16 ft
We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,
[tex]\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{14}{16}\\\\\theta=41.18^{\circ}[/tex]
So, the required angle of elevation of the sun is equal to [tex]41.18^{\circ}[/tex].

Answer:
3x - 4y = -4
Step-by-step explanation:
When you put co-ordinate in it then give zero
3(-4)-4(-2)+3=0
3x-4y=-4 equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2).
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is 3x - 4y = 7
Convert it to slope intercept form
-4y = 7 - 3x
4y=-7+3x
y=-7/4+3/4x
y=3/4x-7/4
3/4 is the slope and the parallel line should also have the same slope.
Now equation of line passing through (-4, -2)
-2=3/4(-4)+b
-2=-3+b
-1=b
So y=3/4x-1
3x-4y=-4 is another equation represents the line which is parallel.
Hence, 3x-4y=-4 equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2).

Absolute value is the direct opposite of a number with a positive value on a number line. However, the absolute value is always answered in a positive form of the number meaning that no matter what the number is (even if it's a positive number) the answer will always be that same number, but in positive form.
Remember, if a number is in between two of these " | " then the answer will be that same number but in positive form.

Complete question :
Determine whether the underlined number is a statistic or a parameter.
"In a study of all 4841 students at a college, it is found that 55% own a computer."
Answer:
because the value is a numerical measurement describing a characteristic of a population.
Step-by-step explanation:
The difference between statistic and parameter lies in the fact that, statistics are used in describing the numerical value obtained from a sample of data. While parameter are used to describe the numerical characteristics of a population.
Hence, all students of a college refers to the population(entire students). Therefore, the numerical characteristics obtained from such data would be called a parameter.

Researchers make a one-sample zzz interval to estimate the proportion of adults who would say they learned something new in the past month. Previous studies have suggested that about 40\%40%40, percent would answer "yes" to this question. The researchers plan on using a confidence level of 95\%95%95, percent, and they want the margin of error to be no more than \pm 5\%±5%plus minus, 5, percent.
Answer:
369
Step-by-step explanation:
The researchers need a sample size of 385 to estimate the proportion of adults who would say they learned something new in the past month with a 95% confidence level and a margin of error of no more than ±5%.
What is a margin of error?The margin of error is the amount of error or uncertainty in a statistical estimate, usually an estimate of a population parameter based on a sample.
We have,
To create a one-sample z-interval, the following steps can be followed:
Determine the sample size (n) and the sample proportion p.
Since no sample size or proportion is given in the problem, we cannot proceed with this step.
Determine the level of confidence (C) for the interval. In this case, the researchers want a confidence level of 95%, so C = 0.95.
Find the critical value (z*) for the level of confidence.
This can be done using a standard normal distribution table or a calculator.
For a 95% confidence level, the critical value is 1.96.
Calculate the margin of error (ME) using the formula:
ME = z x √(p x (1 - p) / n)
Since the margin of error is given as no more than ±5%, we can set it equal to 0.05 and solve for the required sample size:
0.05 = 1.96 x √(0.4 x (1 - 0.4) / n)
Solving for n, we get:
n = (1.96 / 0.05)² x 0.4 x (1 - 0.4)
n ≈ 384.16
Since the sample size must be a whole number, we round up to the nearest integer and get n = 385.
Therefore,
The researchers need a sample size of 385 to estimate the proportion of adults who would say they learned something new in the past month with a 95% confidence level and a margin of error of no more than ±5%.
