Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)
Answer:
18.) x = 6
20.) x = 11
Step-by-step explanation:
18.)
We know that line segments FC and ED are parallel to each other so they are congruent to each other:
-1 + 2x = 5 + x
-1 + x = 5
x = 6
20.)
We know that line segments DE and CF are parallel to each other so they are congruent to each other:
18 = -4 + 2x
22 = 2x
22/2 = x
11 = x
Hope this helps!
A researcher took a random sample of 100 students from a large university. She computed a 95% confidence interval to estimate the average weight of the students at this university. The confidence interval was too wide to provide a precise estimate. True or false
Answer: False
Step-by-step explanation:
All the 100 students engaged in the experiment were picked on the basis that all the students of the university have a chance of being selected. The selected participants must have represented the whole university well.
So, having a 95% confidence interval that the experiment might have atmost 5% error prone is statistically enough and not too wide to give an accurate estimate.
Question mark 1: Match the triangle to correct function and answer
Answer:
Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16
[tex]x \approx 8.479[/tex]
Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18
[tex]x \approx 17.382[/tex]
Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12
[tex]x \approx 15.900[/tex]
Step-by-step explanation:
Each triangle is solved by means of trigonometric relations:
Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16
[tex]\cos 58^{\circ} = \frac{x}{16}[/tex]
[tex]x = 16\cdot \cos 58^{\circ}[/tex]
[tex]x \approx 8.479[/tex]
Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18
[tex]\tan 44^{\circ} = \frac{x}{18}[/tex]
[tex]x = 18\cdot \tan 44^{\circ}[/tex]
[tex]x \approx 17.382[/tex]
Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12
[tex]\sin 49^{\circ} = \frac{12}{x}[/tex]
[tex]x = \frac{12}{\sin 49^{\circ}}[/tex]
[tex]x \approx 15.900[/tex]

Answer:
) Cluster sample.
Step-by-step explanation:
Here are the options
A) Multistage sample.
B) Stratified sample.
C) Cluster sample.
D) Simple random sample.
E) Convenience sample.
A cluster sample is when a population is divided into groups known as clusters. Samples are then randomly selected from this sample. It is a method of probability sampling used for large populations.
The airline first divided the population of travellers by months travelled. this is the cluster. From within the cluster, 10 samples are then chosen
Advantages of a cluster sample
it is faster it is less expensiveIt reduces variabilityDisadvantages of a cluster sample
it only works well when population can be divided into clustersIt is affected by sampling errorWhat is the equation of the line that passes through the points (15, 9) and (-2, 9)?

Answer:
124858
Step-by-step explanation:
The first 4 digits are simple, you multiply the first digit of the equation by the 2nd digit and then for the other 2 you multiply the first digit of the equation by the 3rd digit.
6 + 2 + 8
6 * 2 = 12
6 * 8 = 48
Then the last 2 digits are the sum of the products of the 1 and 2 and 1 and 3 and subtract it by the 2
12 + 48 = 60
60 - 2 = 58

Find the center, vertices, and foci of the ellipse with equation x squared divided by 9 plus y squared divided by 25
Answer:
[tex]C=(0,0)[/tex]
[tex]F=(\pm 4,0)[/tex]
[tex]V=(\pm 5,0)[/tex]
Step-by-step explanation:
From the question we are told that:
The Equation
[tex]\frac{x^2}{9}*\frac{y^2}{25}[/tex]
Generally
From the Equation
[tex]a^2=25[/tex]
[tex]a=5\\b^2=9\\b=3[/tex]
Therefore
[tex]c=\sqrt{a^2-b^2}[/tex]
[tex]c=\sqrt{25-9}[/tex]
[tex]c=\sqrt{16}[/tex]
[tex]c=4[/tex]
Generally the equation for center is mathematically given by
[tex]C=(h,k)[/tex]
[tex]C=(0,0)[/tex]
Generally the equation for foci is mathematically given by
[tex]F=(h,k \pm c,0)[/tex]
[tex]F=(\pm 4,0)[/tex]
Generally the equation for vertice is mathematically given by
[tex]V=(h,k \pm a,0)[/tex]
[tex]V=(\pm 5,0)[/tex]
Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents
Given:
In a circle, two chords AK and LJ intersect each other inside the circle at M.
Measure of arc AJ = 65 degrees.
Measure of arc KL = 85 degrees.
To find:
The measure of angle KML.
Solution:
Intersecting chords theorem: According to this theorem, if two chords intersect each other inside the circle then the measure of angle on the intersection is half of the sum of intercepted arcs.
Using Intersecting chords theorem, we get
[tex]m\angle KML =\dfrac{1}{2}(arcKL+arcAJ)[/tex]
[tex]m\angle KML =\dfrac{1}{2}(85^\circ +65^\circ )[/tex]
[tex]m\angle KML =\dfrac{1}{2}(150^\circ )[/tex]
[tex]m\angle KML =75^\circ[/tex]
Therefore, the measure of angle KML is 75 degrees.
The price of a movie was reduced from $20 to $5. By what percentage was the price of the video game reduced? A 75% B 20% c 5% D 15%
Answer:
A. 75%
Step-by-step
4 * 5 is 20 but when you bring it back down to five you’d be reducing it 75%
the whole thing in a fraction would be 4/4 to 1/4
The price of a movie was reduced from $20 to $5, By the percentage, the price of the video game reduced was 75%.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
The price of a movie was reduced from $20 to $5.
4 x 5 = 20
so, the whole thing in a fraction would be 4/4 to 1/4
From 100% , reducing it by 75%.
By the percentage, the price of the video game reduced was 75%.

Quadrilateral LMNO is a parallelogram, and LM=24-9 and NO=y-2, find the value of "y" and the length of NO.
Answer:
y = 7
NO = 5
Step-by-step explanation:
Let the side of the parallelogram LM and NO given be 2y - 9 and y - 2
Since LMNO is a parallelogram, hence;
LM = NO
2y - 9 = y - 2
2y - y = -2 + 9
y = 7
Since NO = y - 2
NO = 7 - 2
NO = 5

Answer:
x = - 4
Step-by-step explanation:
Given the expression
[tex]\frac{1}{x-1} = \frac{x-2}{2x^2-2}[/tex]
This can also be expressed as;
[tex]\frac{1}{x-1} = \frac{x-2}{2(x-1)(x+1)}\\1 = \frac{x-2}{2(x+1)}[/tex]
Cross multiply
[tex]2(x+1) = x - 2\\2x+2 = x-2[/tex]
Add 2 to both sides

The cost c per person to participate in a guided camping tour depends on the number of n participating in the tour. This relationship can be described by the function c = – 4n + 60, where 0 < n < 12. What is the rate of change described by this function?
Answer:
-4
Step-by-step explanation:
Given the function :
c = – 4n + 60
Where, c = cost of participation ;
n = number of persons
The cost equation can be related to the slope intercept, equation ;
y = mx + b
Where, m = Slope or rate of change
b = intercept
Comparing the slope intercept equation to the cost equation ;
m = - 4 ; Hence, the rate of change of cost is - 4
