Step-by-step explanation:
(a)
The equation of a line in slope- intercept form is
y = mx + c
Given
y - 3 = - 4(x + 2) ← distribute
y - 3 = - 4x - 8 ( add 3 to both sides )
y = - 4x - 5 ← in slope- intercept form
(b)
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
From the slope- intercept form
y = - 4x - 5 ( add 4x to both sides )
4x + y = - 5 ← in standard form
(10,50)(30,86)
slope = (86 - 50) / (30 - 10) = 36/20 = 1.8
y = mx + b
slope(m) = 1.8
(10,50)...x = 10 and y = 50
now sub and find b, the y int
50 = 1.8(10) + b
50 = 18 + b
50 - 18 = b
32 = b
ur equation is : y = 1.8x + 32
when fahrenheit is 20....y = 20
20 = 1.8x + 32
20 - 32 = 1.8x
-12 = 1.8x
-12/1.8 = x
-6.67 = x....celsius would be -6.67
Answer:
The probability of all three children being girls is 0.125.
Step-by-step explanation:
The events of a boy being born and the girl being born is equally likely.
That is, P (G) = P(B) = 0.50.
The gender of <em>n</em>th baby born is independent of the gender of the (<em>n</em> - 1)th baby born.
Compute the probability of all girls as follows:
P (All three girls) = P (G) × P (G) × P (G)
Thus, the probability of all three children being girls is 0.125.
