So firstly, factor out h on the left side:
Next, divide both sides by h:
Lastly, subtract both sides by b and your answer will be
Cot(x)=-3. find sin(x)

Answer:
The Estimate the number of students who took the scores between 82 and 98 = 16
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data The scores on a math test are normally distributed with a mean μ = 74
standard deviation of Population
S.D (σ) = 8
Let 'x' be the random variable of Normal distribution
<u><em>case(i)</em></u>:- when x = 82
<u><em>case(ii)</em></u>:- when x = 98
The probability that test scores between 82 and 98.
P(82≤x≤98) = P(1≤z≤3)
= P(z≤3) - P(z≤1)
= 0.5+A(3)-(0.5+A(1))
= A(3) -A(1)
= 0.4986 - 0.3413
= 0.1573
<u><em>Final answer</em></u>:-
The Estimate the number of students who took the scores between 82 and 98
= 100 X 0.1573 = 15.73 ≅16
Answer:
Table (4)
Step-by-step explanation:
Slope of a line passing through two points and
is,
m =
From the table (1),
Two points lying on the graph are (2, 1) and (6, -1).
Slope of the line = =
From the table (2),
Two points lying on the linear function are (0, 8) and (2, 4).
Slope of the line = = -2
From the table (3),
Two points are (-4, 4) and (-2, 5).
Slope of the line = =
From table (4),
Two points lying on the function are (-2, 0) and (0, 4).
Slope of the line =
Therefore, Table (4) represents a linear function with slope 2.
