Answer:
11. (-4, -1)
12. (2, 7)
Step-by-step explanation:
The midpoint is the average of the end point coordinates. For segment AB, the midpoint M is ...
M = (A+B)/2
If you have A and M, you can find the other end point B from ...
2M = A+B . . . . multiply the above equation by 2
B = 2M -A . . . . subtract A from both sides
__
11. The midpoint (M) is ...
M = ((-1, 2) +(-7, -4))/2 = (-1-7, 2-4)/2 = (-8, -2)/2
M = (-4, -1)
__
12. The missing end point is ...
Z = 2Y -X
Z = 2(-4, 8) -(-10, 9) = (2(-4)+10, 2(8) -9)
Z = (2, 7)

In a cheese factory, 4.5-kg blocks of cheese are cut manually. For a large number of blocks, the standard deviation of the cutting process is measured and found to be 0.10 kg. The measurement was done with a scale with an accuracy of 1.5% of the full scale of 12 kg. Calculate the total uncertainty of the weight of the blocks of cheese at a 95 % confidence level.
Answer:
0.2690 kg
Step-by-step explanation:
Given that:
For cutting a 4.5 kg block of cheese; the standard deviation:
[tex]S_x = 0.1 \ kg[/tex]
For a large no of blocks, at 95% confidence level;
Using the t table; where the degree of freedom is infinity or > 30
t-distribution (t) = 2
∴
[tex]P_x = tS_x[/tex]
[tex]P_x = 2 \times 0.1[/tex]
[tex]P_x = 0.2 \ kg[/tex]
The system uncertainty as a result of the accuracy [tex]B_x[/tex] is:
[tex]B_x = 1.5\% \ of \ reading[/tex]
[tex]B_x = (\dfrac{1.5}{100})(12 kg)[/tex]
[tex]B_x = 0.18 \ kg[/tex]
The total uncertainty for a single experiment with a 95% confidence interval will be:
[tex]w_s = ( B_x^2 + P_x^2)^{\frac{1}{2}[/tex]
[tex]w_s = (0.18^2 + 0.2^2)^{\frac{1}{2}[/tex]
[tex]\mathbf{w_s = 0.2690 \ kg}[/tex]

Write an equation of the line passing through the given points.
(3,-25) and (-3,5)
y=
Answer:
y = -5x -10
Step-by-step explanation:
This is the slope-intercept form:
[tex]y-y_{1} = m(x -x_{1})[/tex]
First, we look for the slope. The slope is found by using the equation:
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1}}[/tex]
[tex]m = \frac{5 - (-25)}{-3 - 3} = \frac{30}{-6} = -5[/tex]
m = -5.
Now, given the two points, our y₁ is -25, and our x₁ is 3. Therefore, we substitute these values into the equation, and get:
y - (-25) = -5(x - 3)
y + 25 = -5(x - 3)
y + 25 = -5x + 15
y = -5x + 15 -25
y = -5x -10
Answer:
the answer to the problem is y= -5x - 10

If an organism has 35% of cytosines, how
many adenines will it have?
35%
15%
25%
Answer:
Unknown
Step-by-step explanation:
Since you have 35 C, you will have 35 G. Without knowing the number of thymine, the number of adenine is unknown .
That is all the information you can get from this. Just because there are 35 C and G, there doesn't have to be an equal number of A and T
Answer: 15%

Hal earns n dollars per hour. Next month he
will receive a 296 raise in pay per hour. The
expression n +0.02n is one way to represent
Hal's pay per hour after the raise Write an
equivalent simplified expression that will
represent his pay per hour after the raise.
Answer:
[tex]Total = 1.02n[/tex]
Step-by-step explanation:
Given
[tex]Earnings = n[/tex]
[tex]Raise = 2\%[/tex] --- not 296
[tex]Total = n + 0.02n[/tex]
Required
Simplify the expression for total earning
The total amount is derived from:
[tex]Total = Earnings + Raise * Earnings[/tex]
[tex]Total = n + 2\% * n[/tex]
Express percentage as decimal
[tex]Total = n + 0.02 * n[/tex]
Now, we can solve further:
[tex]Total = n + 0.02n[/tex]
[tex]Total = 1.02n[/tex]
Hence, the simplified expression is 1.02n
Answer:
1.02n
