Answer:
8x+7
Step-by-step explanation:
2(x-4)+6x-5x3
= 2x-8+6x-5x3
=8x-8+15
=8x+7
Answer:
- 4
Step-by-step explanation:
Substitute x = - 2 into the expression
5x + 6 = 5(- 2) + 6 = - 10 + 6 = - 4
The transformation set of values for function is this is an interval to which sine function maps.
You can observe that the interval to which function maps equals to .
So let us take a look at the possible options.
Option A states that shifting up by would result in having an interval which is clearly not true that means A is false.
Let's try option B. Shifting down by to get would mean that has a transformation interval of . This seems to fit our observation and it is correct.
So the answer would be B. If we shift down by one we get , which means that and .
Hope this helps :)
Answer:
a) 0.383
b) 0.375
Step-by-step explanation:
a) Calculate each z-score.
z = (x − μ) / σ
z₁ = (112 − 118) / 12 = -0.5
z₂ = (124 − 118) / 12 = 0.5
Use a calculator or z-score table to find the probability.
P(-0.5 < Z < 0.5) = 0.6915 − 0.3085 = 0.383
b) 0.383 × 16 ≈ 6. So the expected proportion would be 6/16 = 0.375.
Answer:
None
Step-by-step explanation:
The solution to a system of equations given graphically is at the point of intersection of the 2 lines.
In this case the lines are parallel and never intersect.
Thus the system has no solution.
