Answer:
I believe the answer is 1.3 but really sorry if I'm wrong
A compass is used to copy an angle.
20 miles an hour is a slope of 20 on the miles versus hours graph.
<em>Graph equivalent ratios following a pattern of moving right 1 and up 2 from the original point. </em>
There's no grid shown. Assuming the ticks are 1 each on x and y, right one up two gives a slope of 2, not 20; check that it doesn't say "up 20". If it does check it, as written don't.
<em>Draw a line from the origin that connects all the points. </em>
Is this one of the checkables? If so CHECK ME. The line will have a constant slope of 20 mph.
Every point on the line is an equivalent ratio.
CHECK ME. Is this different than the last one? Yes, each point on the line has a constant ratio, it's 20 miles per hour.
As the line goes up, the speed increases.
The speed is the slope of the line. As we go along a line with constant slope, the speed doesn't change. Don't check.
Alexander can pick any ratio of miles per hour on the line and he will be biking at 20 mph.
Any pair (h,m) on the line through (0,0) and (1,20) will always have m/h=20mph. He can't really pick any ratio; it's always equivalent to 20mph. But as long as he picks from this line he'll be biking at 20mph, so let's CHECK THIS.
Answer:
<h3>36 and 12</h3>
Step-by-step explanation:
Let the two positive integers be x and y.
If their product is 432, then
xy = 432 ......... 1
Also if the sum of the first plus three times the second is a minimum, then;
p(x) = x + 3y
From 1;
y = 432/x ..... 3
Substitute 3 into 2;
p(x) = x+3y
p(x)= x + 3(432/x)
p(x) = x + 1296/x
Since the expression is at minimum when dp(x)/dx = 0
dp/dx = 1 + (-1296)/x²
dp/dx = 1 -1296/x²
0 = 1 -1296/x²
0 = (x²-1296)/x²
cross multiply
0 = x²-1296
x² = 1296
x = √1296
x = 36
Since xy = 432
36y = 432
y = 432/36
y = 12
Hence the two positive numbers are 36 and 12
Answer / Step-by-step explanation:
To properly understand the principle behind the solving of this question, it would be necessary to define and go through some basic terms and their definition.
Therefore to start with, a completely randomized single factor is a type of experiment in which One factor of two or more levels has been manipulated. e.g, the experiment may be investigating the effect of different levels of cost, expenditure or different advertisements
Also, it should be noted that in the area of groping of the experiment, At this point, Each group of different level receives one of the a levels of the independent variable with participants being treated identically in every other respect. The two-group experiment considered previously is a special case of this type of design.
Consequentially, the answer to the narrative of the question would then be:
N= 3 factors levels x 5 replicates = 15
Degrees of freedom for the factor: a – 1 = 3 – 1 = 2
Degrees of freedom Total = 15 – 1= 14
Degrees of freedom error = Total – factor = 14 – 2 = 12
Bounds of P-value for F = 2.91 with 2 and 12 degrees of freedom are
= 0.01 < P < 0.05
