Answer:
The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
Step-by-step explanation:
The slope-intercept form of the line equation
where
In our case, we are given
The slope m = -1/2
Point (2, -3)
now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept
-3 = -1/2(2) + b
-3 = -1 + b
b = -3 + 1
b = -2
now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation
y = mx + b
y = -1/2x + (-2)
y = -1/2x - 2
Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

Answer:
140 oranges
Step-by-step explanation:
From the Question, we know that the pyramid has 7 layers
The number of oranges in the first layer is = 1
Hence, the number of oranges in a pile is calculated as:
1² + 2² + 3² + 4² + 5² + 6² + 7²
= 1 + 4 + 9 + 16 + 25 + 36 + 49
= 140 oranges

Answer:
μ = 1.3468
Step-by-step explanation:
Given data:
Observations
0.85
0.88
0.88
1.06
1.09
1.12
1.29
1.31
1.42
1.49
1.59
1.62
1.65
1.71
1.76
1.83
sum of the observations = 21.55
now,
the total number of the given data, n = 16
now, the mean is given as:
Mean = (Sum of all the observation) / (Total number of observations)
on substituting the values in the above formula, we get
Mean = 21.55 / 16
or
Mean = 1.3468
Since, it is given that the data follows normal distribution.
thus, the normal mean can be used as the point of estimator (μ)
i.e μ = 1.3468
