Answer:
-4c + 5d
Step-by-step explanation:
3 - 7 = -4, so c is equal to -4.
Since there is only one value for d, d stays the same as 5d.
A) The domain remains the same.
Since, in y = - 2 f(x) , the y is whats being multiplied and therefore changed, not the x or domain.
Therefore D[-6,10] <span>
The range is what changes by a factor of -2.
If the original range was [-8,12], then the new one is
[(-8 x -2),(12 x -2)] = [16 , -24].
However, you must flip the numbers to make the interval true, giving you R [-24,16]</span>
Answer: A.
Step-by-step explanation:
Null hypothesis
: A statement describing population parameters as per the objective of the study. It usually takes "≤,≥,=" signs.
Alternative hypothesis 
: A statement describing population parameters as per the objective of the study. It usually takes ">, <, ≠" signs.
Let p be the proportion of screens that will be rejected.
12 percent of the screens manufactured using a previous process were rejected at the final inspection.
(i.e. p= 0.12)
Objective of the study = whether the new process<em> reduces </em>the population proportion of screens that will be rejected
i.e. p< 0.12
So, the appropriate hypotheses to investigate whether the new process reduces the population proportion of screens that will be rejected:
Answer:
114°
Step-by-step explanation:
The measure of an arc is double the measure of the angle between the chord and the tangent line.
Answer:
The slope of one of the guy wires is m=0.7
Step-by-step explanation:
Divide the vertical distance of the guy wire by the horizontal distance of the guy wire to find the slope of one of the guy wire.
We have
d = 100ft ----- horizontal distance
h = 70ft ------- vertical distance
Then,
m = h/d
Put the values in the given formula:
m = 70/100
m = 0.7
Thus the slope of one of the guy wires is m=0.7
