Answer:
C
Step-by-step explanation:
Option c (20, 24, 26) doesn't follow the Pythagoras triplet, it is a not right-angle.
What is the right triangle?The right-angle triangle is a triangle in which the measure of two sides of a triangle is smaller than the longest side of the triangle.
To find the right angle triangle it should satisfy the Pythagoras theorem
a. 12, 16, 20
[tex]12^{2} +16^{2} = 144 + 256[/tex]
= 400
[tex]20^{2}[/tex] = 400
Since it follows the Pythagoras triplet, it is a right-angle triangle.
b. 15, 36, 39
[tex]15^{2} +36^{2} \\= 1521[/tex]
[tex]39^{2} =1521[/tex]
Since it follows the Pythagoras triplet, it is a right-angle triangle.
c. 20, 24, 26
[tex]20^{2} + 24^{2} \\= 976[/tex]
[tex]26^{2} = 676[/tex]
Since it does not follow the Pythagoras triplet, it is a not right-angle triangle.
d. 30, 40, 50
[tex]30^{2} +40^{2} \\= 2500\\50^{2} = 2500[/tex]
Since it follows the Pythagoras triplet, it is a right-angle triangle.
Hence, option c doesn't follow the Pythagoras triplet, it is a not right-angle.

Answer:
25 km/h
Step-by-step explanation:
The relation between speed, time, and distance is ...
speed = distance/time
distance = speed × time
__
The distance relation is used to find the distance on the first line of the table. The problem statement tells you all of the distances are the same.
The speed relation is used to find the speed on the remaining lines of the table. For the average speed, the total distance and total time are used in the computation.
The average speed is 25 km/h.

Mr. Allen has a class of 18 students. He can spend S18 on each student to buy math supplies for the year. He first buys all of his students calculators, which
costs a total of $124.20. After buying the calculators, how much does he have left to spend on each student?
Answer
$199.8
Explanation:
Find the total amount of money he had in the begining. It says that he can spend $18 on each student. He has 18 students so you would multiply that by the $18 he can spend which gives a total of $324 then you subtract the total cost of the calculators from it which then gives you $199.8

The length of a rectangle is 3 yd more than twice the width, and the area of the rectangle is 54 yd?. Find the dimensions of the rectangle.
Answer:
The length of the rectangle is 37 yards, and the width of the rectangle is 17 yards.
Step-by-step explanation:
Given that the length of a rectangle is 3 yards more than twice the width, and the area of the rectangle is 54 yards, the following calculation must be performed to find the dimensions of the rectangle, knowing that the area of a rectangle arises from multiplying its base by its height:
2X + 3 + X = 54
3X + 3 = 54
3X = 54 - 3
X = 51/3
X = 17
(17 x 2) + 3 = 37
Therefore, the length of the rectangle is 37 yards, and the width of the rectangle is 17 yards.

Answer:
968
Step-by-step explanation:
The area of the top and sides is given by the formula ...
A = LW +2H(L +W)
A = (20 cm)(18 cm) +2(8 cm)(20 cm +18 cm)
A = (360 +16(38)) cm² = 968 cm²
Since the tiles are 1 cm², 968 tiles are needed.

Here are summary statistics for randomly selected weights of newborn girls: n=250, x_=32.9 hg, s= 6.9 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 31.9 hg < μ < 34.5 hg with only 19 sample values, x_=33.2 hg, and s=2.6hg? What is the confidence interval for the population mean μ?
Answer:
a) ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) ( 31.74 , 34.66 )
Step-by-step explanation:
n = 250
x ( mean ) = 32.9
std = 6.9
95% confidence interval
df = n - 1 = 250 - 1 = 249
a) construct confidence interval estimate
calculate for the margin of error
= [tex]t_{0.05/2} ,_{250-1} ( \frac{s}{\sqrt{n} } )[/tex] ( using excel function: T.INV.2T(0.025,249) )
= 2.255 ( 6.9 / 15.81 )
= 0.98
Hence the confidence interval for the population
= ( x - 0.98 < μ < x + 0.98 )
= ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) when n = 19
x = 33.2 and std = 2.6
margin of error = [tex]t_{0.05/2} ,_{19-1} ( \frac{s}{\sqrt{n} } )[/tex] = 2.45 * ( 2.6 / 4.36 ) = 1.46
confidence interval
= ( 33.2 - 1.46 , 33.2 + 1.46 )
= ( 31.74 , 34.66 )
Use △GHJ, where A, B, and C are midpoints of the sides.
When AB = 3x+8 and GJ = 2x+24, what is AB?
There are 900 students at a school. You receive two thirds of he votes for best student ever! About how many
votes would you expect to receive?
Answer:
~600 votes
Step-by-step explanation:
Notice how 900 is a multiple of 3. Multiplying by 2/3 is the same as saying as divide the total by 3, then multiply that result by 2. Thusly, 900/3=300 and 300*2=600. Therefore, you should expect around 600 votes.

Can anyone help me with my homework
Answer:
1) NO
2) YES
3) YES
4) YES
Step-by-step explanation:
A function is a relation that maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs).
The condition for a function is that each element in the domain can be mapped into only one element in the range.
(Or each input can be mapped into only one output).
Now let's apply this theory to the exercises here.
In all the cases we have relations, so we need to check if one (or more) of the inputs is mapped into more than one output.
Also remember that in the point notation (x, y) the first value is the input and the second is the output.
1)
Here we can see the points (-1, 5) and (-1, 2)
So the input -1 is mapped into two different outputs, 5 and 2.
This means that this is not a function.
2)
In this case, we can see that all the inputs are different (1, -2, 3, 5), so this is a function.
3)
Again, here we can see that each input is being mapped into only one output, then this is a function.
4)
In a graph, the horizontal position represents the input value and the vertical position represents the output value.
One way to tell if a graph belongs to a function or not, is to see if there is a vertical line such that more than one point intersects that line. If that happens, then we have two points with the same input value but different output value and the relation is not a function.
In this case, we can see that this does not happen, and then we can conclude that the graph represents a function.

Answer:
PQ=36
Step-by-step explanation:
If the triangles are similar, then they must have a common ratio between them.
RQ corresponds with CB, so [tex]\frac{84}{18}=\frac{14}{3}[/tex]
If the ratio is [tex]\frac{14}{3}[/tex], then [tex]\frac{168}{\frac{14}{3}}=36[/tex], so PQ=36.

9514 1404 393
Answer:
12. C
13. D
Step-by-step explanation:
12. For interest r on principal P compounded n times per year for t years, the account balance is ...
A = P(1 +r/n)^(nt)
For P=800, r=0.05, n=365, t=6, this becomes ...
A = 800(1 +0.05/365)^2190 . . . . matches choice C
Note: if you're familiar with the formula, you will notice choice C is the only one with 'n' in the right place.
__
13. The form of an exponential function is ...
y = a·b^x . . . . . . . . where 'a' is the initial value, and 'b' is the growth factor
The form of the equation eliminates choices A and B.
Here, the initial value is 1.87, eliminating choice C.
Matching the problem statement to the form of the exponential function we see that the equation of choice D is appropriate.
