Answer:
0.4394
Step-by-step explanation:
given that an auto parts store is examining how many items were purchased per transaction at the store as compared to their online website
The data is shown below:
Frequency Frequency*Midpt
Midpt Online Total Online Total
1-3 2 40 147 80 294
4-6 5 60 103 300 515
7-9 8 15 32 120 256
10-12 11 5 18 55 198
120 300 555 1263
Thus we find total items purchased on line = 555
and total items overall purchased = 1263
Hence the probability that a randomly selected item was purchased online
=
Answer:
-62.8 is the answer .......................
-5(x – 3) = x + 27
multiply the bracket by -5
(-5)(x)=-5x
(-5)(-3)=15
-5x+15=x+27
Move +15 to the other side. Sign changes from +15 to -15.
-5x+15-15=x+27-15
-5x=x+27-15
-5x=x+12
Move +x to the other side. Sign changes from +x to -x.
-5x-x=x-x+12
-6x=12
Divide both sides by -6
-6x/-6=12/-6
Answer: x=-2
Answer:
x=27, y=18
Step-by-step explanation:
Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.
