20.8,15,17
21.2,4,7
22.7,24,25
23.3,9,10
24.12,13,25
Answer:
Step-by-step explanation:
Apply the Pythagorean Theorrem. Find the sum of the squares of the two shortest sides and determine whether this sum equals the square of the longest side:
#19: 5^2 + 12^2 = ? = 13^2
25 + 144 = ? = 169 This is true, so you do have a right triange in #19.
#21: 2^2 + 4^2 = ? = 7^2, or 4 + 16 = ? = 49 This is false. Not a right
triangle.
Apply this same approach (Pythagorean Theorem) to the remaining problems.

The lengths of a certain species of fish are approximately normally distributed with a given mean ll and standard
deviation. According to the Empirical Rule, what percentage of the fish will have lengths within 1 standard deviation
of the mean?
-34%
-47.5%
-68%
-99.7%
The percentage of fish which will have the lengths within 1 standard deviation of the mean is 68%.
What is Empirical Rule?Empirical rule is a rule for normally distributed data which defines that almost all the data observed ranges between three standard deviations from the mean.
According to empirical rule,
68% of the data lies in the standard deviation of ±1.
95% of the data lies in the standard deviation of ±2.
99.7% of the data lies in the standard deviation of ±3.
Given,
The lengths of a certain species of fish are approximately normally distributed with a given mean and standard deviation.
According to the Empirical Rule, 68% of the fish will have lengths within 1 standard deviation of the mean.
Hence the required percentage is 68%.

A certain bank offers a car loan with a fixed annual interest rate. Justine applied for the loan and used the entire amount to buy a car worth $43,000. He had to pay the bank for five years for a total amount of $51,600. How much would be the yearly interest if Justine borrowed $50,000 instead? *
0 points
Answer: $10000
Step-by-step explanation:
From the question,
Principal = $43000
Time = 5 years
Rate = Unknown
Simple Interest = $51,600 - $43000 = $8600
We need to calculate the rate of interest which will be:
Interest = PRT/100
8600 = (43000 × 5 × Rate) / 100
Cross multiply
8600 × 100 = 215000 × Rate
Rate = 860000 / 215000
Rate = 4%
Assuming Justine borrowed $50,000 instead, the yearly Interest will be:
= (50000 × 5 × 4%)
= 50000 × 5 × 0.04
= $10000
Find the value of x and y. Triangle MNP = triangle TUS
Answer:
x = 32, y = 51
Step-by-step explanation:
Since the triangles are congruent then corresponding sides and angles are congruent, that is
∠ U = ∠ N
∠ N = 180° - (142 + 24)° = 180° - 166° = 14° , then
2x - 50 = 14 ( add 50 to both sides )
2x = 64 ( divide both sides by 2 )
x = 32
and
NP = US
2x - y = 13
2(32) - y = 13
64 - y = 13 ( subtract 64 from both sides )
- y = - 51 ( multiply both sides by - 1 )
y = 51
Using the triangle theorem, the values of x and y is 32° and 51° respectively
From △MNP
∠M + ∠N + ∠P = 180° (Sum of interior angles in a triangle)
N = 180 - (142 + 24)
N = 180 - 168
N = 14°
Equate the expression :
2x - 50 = 14
2x = 14 + 50
2x = 64
x = 64 / 2
x = 32°
From ; 2x - y = 13 _____(1)
Substitute x = 32 into the expression ;
2(32) - y = 13
64 - y = 13
64 - 13 = y
51° = y
Therefore, the values of x and y is 32° and 51° respectively.

Answer:
∠ X = 80° , ∠ V = 60°
Step-by-step explanation:
(a)
Since XY and WX are congruent then the triangle is isosceles and the 2 base angles are congruent, that is
∠ W = ∠ Y = 50° , so
∠ X = 180° - (50 + 50)° ← sum of angles in triangle
∠ X = 180° - 100° = 80°
(b)
Since the 3 sides are congruent then the triangle is equilateral with the 3 angles congruent, each 60°
∠ V = 60°

“28 is 40% of what number?” i got 70, is that correct?

70
You got it correct :)
Step-by-step explanation:
[tex]\frac{28}{y} =\frac{40}{100}[/tex]
y × 40 = 100 × 28
40y = 2800
40y ÷ 40 = 2800 ÷ 40

20 people applied for a job. Everyone either has a school certificate or diploma or even both. If 14 have school certificates and 11 diplomas how many have a school certificate only
Given:
Either has a school certificate or diploma or even both = 20 people
Having school certificates = 14
Having diplomas = 11
To find:
The number of people who have a school certificate only.
Solution:
Let A be the set of people who have school certificates and B be the set of people who have diplomas.
According to the given information, we have
[tex]n(A)=14[/tex]
[tex]n(B)=11[/tex]
[tex]n(A\cup B)=20[/tex]
We know that,
[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]
[tex]20=14+11-n(A\cap B)[/tex]
[tex]20=25-n(A\cap B)[/tex]
Subtract both sides by 25.
[tex]20-25=-n(A\cap B)[/tex]
[tex]-5=-n(A\cap B)[/tex]
[tex]5=n(A\cap B)[/tex]
We need to find the number of people who have a school certificate only, i.e. [tex]n(A\cap B')[/tex].
[tex]n(A\cap B')=n(A)-n(A\cap B)[/tex]
[tex]n(A\cap B')=14-5[/tex]
[tex]n(A\cap B')=9[/tex]
Therefore, 9 people have a school certificate only.

Step-by-step explanation:
3(x +2 ) = 18 {Use distributive property: a(b +c) =a*b + a*c}
3*x +3*2 = 18
3x + 6 = 18 {Subtract 6 from both sides}
3x = 18- 6
3x = 12 {Divide both sides by 3}
x = 12/3
x = 4
