Answer:
no, the triangles are not similar
Step-by-step explanation:
The given ratios tell you corresponding side ratios are ...
ED : DC : EC = 8 : 10 : 12 = 4 : 5 : 6
AB : BC : AC = 12 : 15 : 21 = 4 : 5 : 7
Corresponding sides do not have the same ratios. The given information can be used to prove the triangles are NOT similar.

Answers
Answer:
Step-by-step explanation:
From the given information:
Note that the possible values of Y are 0 and 1 because;
y = 0 if X = 0 and y = 1 if X = ±1
∴
[tex]P(Y =0) = P(X = 0) =\dfrac{1}{3}[/tex]
[tex]P(Y = 1) = P(X = -1 \ or \ 1) \\ \\ = P(X = -1) + P(X = 1)[/tex]
[tex]= \dfrac{1}{2}+ \dfrac{1}{6}[/tex]
[tex]=\dfrac{3+1}{6}[/tex]
[tex]= \dfrac{2}{3}[/tex]
b)
[tex]E(|X|) = \sum |x| P(X=x) = ( 1 \times \dfrac{1}{2}) + ( 0\times \dfrac{1}{3}) + ( 1 \times \dfrac{1}{6})[/tex]
[tex]= \dfrac{2}{3}[/tex]
Mila bought slippers worth PHP240.00 with a discount of 25% how much money will she pay
A.PHP 180.00
B.PHP 200.00
C.PHP 220.00
Answers
Answer:
A.PHP 180.00
Step-by-step explanation:
Given the following data;
Selling price = PHP240.00
Discount = 25% = 25/100 = 0.25
To find the amount she paid;
Discount price = 240 * 0.25
Discount price = PHP60
Amount paid = Selling price - discount price
Amount paid = 240 - 60
Amount paid = PHP180
Therefore, Mia would pay PHP180 for the slippers.

What is the area, in square feet, of the rectangle shown below?
Answers
Answer:
D
Step-by-step explanation:
= 34/5 × 19/4
= 646/20
= [tex]32 \frac{6}{20} [/tex]
The area of the given rectangle is [tex]32\frac{6}{20}[/tex] square feet
For better understanding check the calcualtion here .
Calcualtion :
Area of the rectangle is the space inside the given triangle .
Formula : Formula to find the area of the triangle is length times width
Length and width are given as mixed fractions
Lets convert mixed fractions into improper fractions
[tex]Length =6\frac{4}{5}=\frac{6 \cdot 5+4}{5}=\frac{34}{5} \\Width=4\frac{3}{4}=\frac{4 \cdot 4+3}{4}=\frac{19}{4}[/tex]
Now we find out the area
[tex]Area= length \cdot width \\Area=\frac{34}{5} \cdot \frac{19}{4} \\Area= \frac{646}{20}[/tex]
Now we divide the number and find out the quotient and remainder
[tex]Area= \frac{646}{4} \\Quotient = 32 \\remainder =6\\Area= 32\frac{6}{20}[/tex]
The area of the given rectangle is [tex]32\frac{6}{20}[/tex] square feet

Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
32.3 , 28.8 , 29.1 , 29.5 , 30.8 , 31.0 , 17.5 , 34.5 , 23.5 , 33.0 , 31.7 , 28.6 , 27.4
Reordered data:
17.5, 23.5, 27.4, 28.6, 28.8, 29.1, 29.5, 30.8, 31.0, 31.7, 32.3, 33.0, 34.5
The mean ; m
Mean, m = Σx /n
Σx = 377.7
n = sample size = 13
m = Σx / n = 377.7 / 13 = 29.05
Median = 1/2(n+1)th term
= 1/2(14) = 7th term = 29.5
Range = maximum - minimum
Range = 34.5 - 17.5 = 17
Lower quartile (Q1) = 1/4(n+1)th term
1/4(14)th term = 3.5th term
(3rd + 4th) / 2
= (27.4 + 28.6) / 2
= 28
Upper quartile (Q3) = 3/4(n+1)th term
3/4(14)th term = 10.5th term
(10th + 11th) / 2
= (31.7 + 32.3) / 2
= 32
IQR = Q3 - Q1
IQR = 32 - 28 = 4
Variance : (V) = Σ(x - m)²/n-1
[(32.3-29.05)^2 +(28.8-29.05)^2 + (29.1 - 29.05)^2 + (29.5-29.05)^2 + (30.8-29.05)^2 + (31.0-29.05)^2 + (17.5 - 29.05)^2 + (34.5-29.05) ^2 + (23.5-29.05)^2 + (33.0-29.05)^2 + (31.7-29.05)^2 + (28.6-29.05)^2 + (27.4 - 29.05)^2] / 12
Variance = 19.76
Standard deviation = sqrt(variance)
Standard deviation = sqrt(19.76)
Standard deviation = 4.45

The cost of shipping a package is $2.75 per pound. Jeremy wants to ship a package that has a mass of 15 kg. How much will it cost Jeremy to ship this package? Use 1 kg = 2.2 lbs.
Answers
Answer:
$90.75
Step-by-step explanation:
First we convert kilograms to pounds.
1 kg = 2.2 lb
15 kg = 15 * 2.2 lb = 33 lb
Cost of shipping: $2.75/lb
Cost of shipping 33 lb: 33 lb * 2.75/lb = $90.75

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.5 parts/million (ppm). A researcher believes that the current ozone level is not at a normal level. The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the value of the test statistic. Round your answer to three decimal places.
Answers
Answer:
The value of the test statistic is [tex]t = 2.1[/tex]
Step-by-step explanation:
Our test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected value, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
The level of ozone normally found is 7.5 parts/million (ppm).
This means that [tex]\mu = 7.5[/tex]
The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7.
This means that [tex]X = 7.8, \sigma = 0.7, n = 24[/tex]
Test Statistic:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{7.8 - 7.5}{\frac{0.7}{\sqrt{24}}}[/tex]
[tex]t = 2.1[/tex]
The value of the test statistic is [tex]t = 2.1[/tex]

Answer:
∡A = 48°
∡B = 58°
∡BCA = 74°
Step-by-step explanation:
start by finding m∡BCA; this angle is supplementary with ∡BCD and the pair must add up to 180. therefore, m∡BCA = 74°
all three interior angles of a triangle must add up to 180:
74 + 4y + 3y + 22 = 180
96 + 7y = 180
7y = 84
y = 12
substitute '12' for 'y' in 3y + 22 to get 58
