Answer:
The plant grows 1 cm every day is the incorrect statement
Step-by-step explanation:
The graph shows that for every 10 days the plant grows 1 cm
10/2 = 5
so in 5 days the plant would grow half of what it does in 10 days so 1/2 or 0.5 cm
10/10 = 1
so in 1 day the plant would grow a tenth of what it does in 10 days so 1/10 or 0.1 cm

Answer:
x = 2
Step-by-step explanation:
1 - 3x = -5
Subtract 1 from each side
1-3x-1 = -5-1
-3x = -6
Divide each side by -3
-3x/-3 = -6/-3
x = 2
Answer:
34% of lightbulb replacement requests numbering between 47 and 52
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 52
Standard deviation = 5
Between 47 and 52:
52 is the mean and 47 is one standard deviation below the mean.
By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean.
Since the normal distribution is symmetric, of those, 34% are within 1 standard deviation below the mean and the mean(47 and 52) and 34% are within the mean and one standard deviation above the mean(52 and 57).
So
34% of lightbulb replacement requests numbering between 47 and 52
Here is your answer
REASON:
Theorem used: The diagonals of a parallelogram bisect each other.
Let diagonals AC and BD bisect each other at O
So, OA=OC
Now,
3x=4x-6 [OA=3x and OC=4x-6]
4x-3x= 6
x= 6
