Answer:
3/4b−2/3b=−9 = -108. so, i just used equivalent fractions of both of those numbers :D
Step-by-step explanation:
6/8b - 4/6b = -9
The equation of the line is 
Explanation:
Given that the line passes through the points (-5,-3)
The slope of the line is 
We need to determine the equation of the line.
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Let us substitute the points (-5,-3) and the slope in the above formula.
Thus, we have;
Simplifying, we get;
Subtracting 3 from both sides of the equation, we get;
Hence, the equation of the line in slope - intercept form is
This question is incomplete, the complete question is;
Let X denote the time in minutes (rounded to the nearest half minute) for a blood sample to be taken. The probability mass function for X is:
x 0 0.5 1 1.5 2 2.5
f(x) 0.1 0.2 0.3 0.2 0.1 0.1
determine;
a) P( X < 2.5 )
B) P( 0.75 < X ≤ 1.5 )
Answer:
a) P( X < 2.5 ) = 0.9
b) P( 0.75 < X ≤ 1.5 ) = 0.5
Step-by-step explanation:
Given the data in the question;
The probability mass function for X is:
x 0 0.5 1 1.5 2 2.5
f(x) 0.1 0.2 0.3 0.2 0.1 0.1
a) P( X < 2.5 )
P( X < 2.5 ) = p[ x = 0 ] + p[ x = 0.5 ] + p[ x = 1 ] + p[ x = 1.5 ] + p[ x = 2 ]
so
P( X < 2.5 ) = 0.1 + 0.2 + 0.3 + 0.2 + 0.1
P( X < 2.5 ) = 0.9
b) P( 0.75 < X ≤ 1.5 )
P( 0.75 < X ≤ 1.5 ) = p[ x = 1 ] + p[ x = 1.5 ]
so
P( 0.75 < X ≤ 1.5 ) = 0.3 + 0.2
P( 0.75 < X ≤ 1.5 ) = 0.5
This answer will probably be 3/20 x not sure
M = milk
C= cheese
X=meat
milk = 0.5c
meat = 4c
cheese = 1c
<span>4 +0.5 = 1c = 5.5c</span>
C= 42/5.5 = 7.64
X = 7.64 x 4 = 30.56
M =7.64 * 0.5 = 4.67
30.56 + 3.82 + 7.64 = approximately $42
