Given:
The height of 44 students (in centimeter) are presented in the given frequency distribution.
To find:
The median of the given data.
Solution:
The given intervals are inclusive first make the intervals exclusive by adding 0.5 in upper limit and by subtracting 0.5 from the lower limit.
The complete frequency distribution table is shown below:
Height Frequency L <cf
182 - 188 1 181.5 - 188.5 44
175 - 181 3 174.5 - 181.5 43
168 - 174 6 167.5 - 174.5 40
161 - 167 15 160.5 - 167.5 34 Median class
154 - 160 12 153.5 - 160.5 19
147 - 153 4 146.5 - 153.5 7
140 - 146 3 139.5 - 146.5 3
We have, [tex]n=44[/tex].
[tex]\dfrac{n}{2}=\dfrac{44}{2}[/tex]
[tex]\dfrac{n}{2}=22[/tex]
The 22th term is include in the class 160.5 - 167.5 because is cf is greater than 22 but the cf of o preceding class is less than 22. So, it is the median class is 160.5 - 167.5.
Formula for median:
[tex]Median=l+\dfrac{\dfrac{n}{2}-cf}{f}\times h[/tex]
Where, l is the lower limit of median class, cf is the cumulative frequency of preceding class, f is the frequency of median class and h is the size of the class.
Now, [tex]l=160.5,f=15,cf=19,h=7[/tex].
[tex]Median=160.5+\dfrac{22-19}{15}\times 7[/tex]
[tex]Median=160.5+\dfrac{3}{15}\times 7[/tex]
[tex]Median=160.5+1.4[/tex]
[tex]Median=161.9[/tex]
Therefore, the median of the given data table is 161.9.

In the following triangle, angle A measures 49° and angle C measures
62.
Answer:
The measure of angle B is 69°.
Step-by-step explanation:
All angles of the triangle should add up to 180°, so you add angle A and angle C together, and then subtract that number from 180.
49 + 62 = 111
180 - 111 = 69
69°

What is the height, x, of the equilateral triangle?
Given:
The figure of an equilateral triangle with side length 14 in.
To find:
The height x of the equilateral triangle.
Solution:
We know that the height of an equilateral triangle is:
[tex]h=\dfrac{\sqrt{3}}{2}a[/tex]
Where, a is the length of side of the equilateral triangle.
It is given that the height of the triangle is [tex]x[/tex].
Putting [tex]a=14,h=x[/tex] in the above formula, we get
[tex]x=\dfrac{\sqrt{3}}{2}(14)[/tex]
[tex]x=\sqrt{3}(7)[/tex]
[tex]x=7\sqrt{3}[/tex]
Therefore, the height of the triangle is [tex]x=7\sqrt{3}[/tex].

Answer:
F - 20 songs
Step-by-step explanation:
Sandra has $120. Each gift card costs $12.
$120 ÷ $12 = 10. So, Sandra buys 10 gift cards.
Each gift card can be used to download 10 songs. So, 10 gift cards can be used to download 10 × 10 = 100 songs.
There are 5 children. Each child can download 100 ÷ 5 = 20 songs.

Essentially, what we're looking at here are two alternate interior angles.
Wait. What? Alternate interior angles?
It sounds like some super fancy math jargon, but it's a fairly simple concept that I'll try my best to explain. First, let's look at lines L and M as two parallel lines, meaning that these two are lines with equal slopes, and will never intersect. See that line that goes in between the parallel lines L and M? That's called a transversal. It's basically a line that goes through two parallel lines.
Now we know that there's a transversal going through the parallel lines. So what? Well, there's a couple of special attributes to transversals. See the two angles, 7x-7 and 4x+14? As you can tell, these two angles alternate in the interior space between the transversal and the parallel lines.
Alternate interior angles are equal. There's a way to prove that they're equal, but I won't bore you with the specifics since that's not what the question's asking.
If the angles need to be equal for lines L and M to be parallel, we can make an equation that'll solve for x:
7x - 7 = 4x + 14
Subtract 4x from both sides:
7x - 4 x - 7 = 4x - 4x + 14
3x - 7 = 14
Add 7 to both sides:
3x - 7 + 7 = 14 + 7
3x = 21
Divide both sides by 3 to completely isolate x:
[tex]\frac{3x}{3}[/tex] = [tex]\frac{21}{3}[/tex]
x = 7
And that's our answer! If you need me to explain anything any further, just ask!

Find the area of this triangle.
Round to the nearest tenth.
Answer:
42.4 m²
Step-by-step explanation:
The formula for the Area of this triangle = 1/2 absinθ
a = 8m
b = 12m
θ = 62°
The area of the triangle =
1/2 × 8m × 12m × sin 62
= 42.38 m²
Approximately = 42.4 m²

In a small town of 5,832 people, the mayor wants to determine the proportion of voters who would support an increase to the food tax. An assistant to the mayor decides to survey 1,000 randomly chosen people to construct a 90% confidence interval for the true proportion of people who would support the increase in food tax. Of the sample, 363 people say they would support the increase. Are the conditions for inference met?
Yes, the conditions for inference are met.
No, the 10% condition is not met.
No, the randomness condition is not met.
No, the Large Counts Condition is not met.
Answer:
No, the 10% condition is not met is the answer.
1,000/5,832 is 0.1714, or ~17%, which is more than 10% of the population.
No, the 10% condition is not met.
Ratio:
'Ratio is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another.'
Proportion:
'A proportion is an equation in which two ratios are set equal to each other.'
According to the given problem,
Total number of people in the town = 5832
Number of people to be surveyed = 1000
Ratio of number of people chosen to the total population = [tex]\frac{1000}{5832}[/tex]
= 0.17
Therefore percentage of people to be surveyed = 0.17 × 100
= 17%, which is more than 10%
Hence, we can conclude that the 10% condition is not met.
