Answer:
Step-by-step explanation:
A. S=strawberry, C=chocolate
S+C=14 equation 1
2s+3c=30 equation 2
B. -2(s+c)=-2(14) multiply equation 1 by -2 to use elimination method
-2s+-2c=-28 modified Equation 1
2s+ 3c=30. Equation 2
C=2 add above two equations.
solve for s
s+c=14
s+2=14
s=12
Used elimination method since it was easier to add the two equations.
check answer by inputting s,c values in either equation.
2s+3c=30
2(12)+3(2)=30
24+6=30
30=30

Answer: Mean = 218.9.</h3><h3>Median = 229</h3><h3>Mode = Zero mode.</h3>
Step-by-step explanation:
Given blood cholesterol level was measured for each of 8 adults (in mg/dL) are:
264, 191, 160, 148, 262, 212, 268, 246
In order to find the mean, we need to add all those 8 numbers and divide by 8.
Therefore, mean = 
<h3>Mean = 218.9.</h3>
In order to find the median, we need to arrange them in ascending order:
148, 160, 191, 212, 246, 262, 264, 268.
The middle most two values are 212 and 246.
Therefore, median = 
<h3>Median = 229.</h3>
<h3>Therefore, Mode = Zero mode.</h3>
A line has an arrow on each end of the line. A segment has a dot or point on each end of the line.
Answer:
-58
Step-by-step explanation:
8*3*-2=-48
-48-2*5=-58
Answer:
Total ribbons = 3 + 12 = 15So, 3/15 = black12/15 = greenTherefore the probability Lila selects the black ribbon first is 12/15Because Lila has taken one
