Answer:
S_n = 99.18
Step-by-step explanation:
The series is;
200, -160, 128...
Now,the common ration would be gotten by dividing two consecutive terms i.e. a2/a1, a3/a2, a4/a3 e.t.c.
Now,
r = -160/200
r = -4/5
Formula for sum of geometric series is;
S_n = a1(1 - rⁿ)/(1 - r)
Where a1 is the first term and n is the number of terms in the series.
In this case;
a1 = 200
n = 10
Thus;
S_n = 200(1 - (-4/5)^(10))/(1 - (-4/5))
S_n = 99.18
A segment has an endpoint at (2, 4) and a midpoint at (4, -2). What are
the coordinates of the other endpoint?
Answer: (6, -8)
Step-by-step explanation: endpoint 1 is 6.3 away from the midpoint. Double that makes 12.6, so find the point that is 12.6 away from the original endpoint. Using a graph helps! I personally use geogebra.

22,5,22,13,12,24,24,9,24,19 range mean median and mode
Answer:
19 is the range.
17.4 is the mean.
20.5 is the median.
24 is the mode.
Step-by-step explanation:
Range - The difference of the largest number and the smallest numberMean - To calculate the mean, add up all the numbers, then, divide the sum by the count.Median - The "middle" number after putting the numbers in numerical orderMode - The most frequently appearing numbers-------------------------------------------------------------------------------------------------------------
22, 5, 22, 13, 12, 24, 24, 9, 24, 19.
Now that we know what these words mean, we can solve this.
Range: 24 - 5 = 19
19 is the range.
-------------------------------------------------------------------------------------------------------------
Now, let's calculate the mean.
Mean: 22 + 5 + 22 + 13 + 12 + 24 + 24 + 9 + 24 + 19 = 174
There are 10 numbers in total.
174 ÷ 10 = 17.4
17.4 is the mean.
-------------------------------------------------------------------------------------------------------------
5, 9, 12, 13, 19, 22, 22, 24, 24, 24
In this case, there are two medians.
So to find the median, we have to add both the medians of this data set, then, divide the sum by 2.
19 + 22 = 41
41 ÷ 2 = 20.5
20.5 is the median.
-------------------------------------------------------------------------------------------------------------
5, 9, 12, 13, 19, 22, 22, 24, 24, 24
24 appears the most; 24 is the mode.

Answer:
A) answer c ; B) X+3.7=15.3 ; C) 15.3 - 3.7 = 11.6 ---> 11.6+3.7=15.3
Step-by-step explanation:
Solution for A: First you have to look for the line underneath the bar says 15.3 as this will represent the total amount of liters in the bucket altogether. This would be bar c since we also know that we have 3.7 liters added but are missing the amount that was previously inside the bucket.
Solution for B: Let X resemble the unknown amount of water. To solve B, we need to write an equation. We know that there was already an amount of water in the bucket prior to us pouring more in so X is our first addend. We then added 3.7 liters of water to the unknown amount so that is our next addend giving you X+3.7=15.3
Solution for C: Now that we know our equation, we do the inverse operation (subtraction) in order to figure out the missing amount of water. This means we do
15.3 - 3.7 = 11.6

Write the equation of the line that passes through the points (7, -3) and (7, 0).
Answer:
x = 7
Step-by-step explanation:
Since the x- coordinates of the 2 points are equal, both 7 , then the line is vertical with equation
x = c
where c is the value of the x- coordinates the line passes through, then
x = 7 ← equation of line
Answer:
I hope this is right, im not sure because they are coincides or the same lines when overlapped, but I tried.
3x+0
Step-by-step explanation:
Using the formula mx+b we can get our answer.
We know that the two points pass through (7, 0)
mx+b is (slope)x+(y-intercept)
The slope of the two lines is 3 so we can replace m for 3:
3x+b
the y-intercept does not exist for these two lines as they are coincides, so we can just put it at 0, so we now have our equation 3x+0.

A slide was installed at the local swimming pool, as shown here
What is the length of the slide?
Answer:
21.47 ft (rounded to the near hundreths)Step-by-step explanation:
Pythagorean Theorem : Right triangle with legs a and b and hypotenuse c
a=19 b = 10 c= x
19² + 10² = x²361 +100 = x²461 = x²x = square root of 461
x= 21.4709... (21.47 )
The required length of the slide installed at the local swimming pool is 21.47 ft.
A slide was installed at the local swimming pool, as shown here, what is the length of the slide is to be determined.
Perpendicular length = 10ft
base length = 19ft
In a right-angled triangle, its side of the right angle triangle, such as hypotenuse, perpendicular, and base are Pythagorean triplets.
Let the length of the slide at the local swimming pool is x,
applying Pythagorean theorem
hypotenuse² = perpendicular² + base²
x² = 19² + 10²
x² = 361 +100
x² = 461
x = √461
x = 21.47 ft
So, x = 21.47 is the length of the slide.
Thus, The required length of the slide installed at the local swimming pool is 21.47 ft.

Kelly's little brother is exactly 3 feet tall. How tall is he in inches?
Answer:
he is 36 inches
Step-by-step explanation:
Answer:
36 inches
Step-by-step explanation:
We know that Kelly's little brother is exactly 3 feet tall, and we know how big he is in inches.
To solve first keep in mind that 1 feet is 12 inches.
Therefore if there are 3 feet, we would multiply the inches 3 times.
12 * 3
= 36
Therefore, Kelly's little brother is 36 inches.

Answer:
∠1 = 142°
reason: angles 1 and 2 are supplementary so they equal 180. 180-38 is 142
∠3 = 38°
reason: angles 2 and 3 are adjacent angles because they are diagonal from each other so they will equal the same measure.
∠4 = 142°
reason: since angle 4 is adjacent to angle 1 and is supplementary to angle 3, it has to be 142
∠5 = 38°
reason: since it is a transversal that means both of the intersections are the same measurements. so angle 5 is 38 since it matches up with angle 2
∠6 = 142°
reason: for the same reason as angle 5. angle 6 matches up with angle 1 so it has to equal 142.
∠8 = 142°
reason: since angle 8 is adjacent to angle 6 it has to equal 142. angle 8 is also a transverse angle to angle 4. and since angle 4 also equals 142, 8 has to also

For the following hypothesis test, determine the null and alternative hypotheses. Also, classify the hypothesis test as two-tailed, left-tailed, or right-tailed. The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months. A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
Choose the correct null and alternative hypotheses below.
A. H0: μ = 22.1 months
Ha: μ > 22.1 months
B. H0: μ = 22.1 months
Ha: μ 22.1 months
C. H0: μ = 22.1 months
Ha: μ < 22.1 months
D. H0: μ > 22.1 months
Ha: μ = 22.1 months
E. H0: μ 22.1 months
Ha: μ = 22.1 months
F. H0: μ = 22.1 months
Ha: μ > 22.1 months
Which of the following is the correct classification of the hypothesis test?
A. Two-tailed
B. Left-tailed
C. Right-tailed
Answer:
Option B:
[tex]H_0: \mu = 22.1[/tex]
[tex]H_a: \mu \neq 22.1[/tex]
Classification:
The hypothesis test is Two-tailed.
Step-by-step explanation:
The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months.
This means that the null hypothesis is that the mean is of 22.1 months, that is:
[tex]H_0: \mu = 22.1[/tex]
A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
At the alternate hypothesis, we test if this mean is different of 22.1, that is:
[tex]H_a: \mu \neq 22.1[/tex]
Which means that the answer is given by option b).
Which of the following is the correct classification of the hypothesis test?
We test if the mean is different from a value, which means that the hypothesis test is Two-tailed.
