Answer:
y = 2x + 11
Step-by-step explanation:
Slope-intercept form (y=mx+b) of linear equations highlights the slope (m) and the y-intercept (b) of a line.
Slope = m = rise/run = (y2-y1)/(x2-x1) = (15-21)/(2-5) = -6/-3 = 2
substitute 2 back into the equation.
y = mx + b
y = 2x + b
use one of the provided points to solve for b.
y = 2x + b
15 = 2(2) + b
15 = 4 + b
11 = b
y = 2x + 11

What is the elevation of the bottom of
the canyon?
Answer:
145 feet.
Step-by-step explanation:
Given that:
An underwater canyon begins at depth = 40 ft
Depth of canyon = 105 ft
To find:
The elevation of the bottom of the canyon = ?
Solution:
Kindly refer to the image attached for the given dimensions.
A is the sea level.
B is the point at which the canyon starts and
C is the bottom of the canyon.
As per question statement, we are given that:
AB = 40 feet
BC = 105 feet
And we have to find the distance AC = ?
It is clearly observable that:
So, the elevation of the bottom of the canyon is 145 ft.
Answer:
0.9533
Step-by-step explanation:
(a) Probability that a randomly selected woman's height is less than 65 inches:
Using the z-score formula:
�
=
�
−
�
�
Z=
σ
X−μ
Where:
�
X = 65 inches
�
μ = 64.3 inches
�
σ = 2.7 inches
�
=
65
−
64.3
2.7
≈
0.2593
Z=
2.7
65−64.3
≈0.2593
Now, find the probability associated with this z-score, which is approximately 0.6010 (rounded to four decimal places).
(b) Probability that the mean height of 43 randomly selected women is less than 65 inches:
Using the Central Limit Theorem:
�
μ (mean of the sample means) remains 64.3 inches.
�
sample mean
σ
sample mean
(standard deviation of the sample means) is calculated as
2.7
43
≈
0.4115
43
2.7
≈0.4115.
Now, find the z-score for a sample mean of 65 inches:
�
=
65
−
64.3
0.4115
≈
1.6924
Z=
0.4115
65−64.3
≈1.6924
The probability associated with this z-score is approximately 0.9533 (rounded to four decimal places).
