Step-by-step explanation:
Given:
for one batch of sidewalk chalk = 
cup plaster of paris.
Number of bathes = 3
We need to find quantity of plaster of paris.
Solution:
For making 1 batch of sidewalk chalk = cup plaster of paris.
For making 3 batches of sidewalk chalk = 
cup plaster of paris.

Answer:
351 carrots
Step-by-step explanation:
13 = 1 tens + 3 units
27 = 2 tens + 7 units
<h3>13 × 27</h3>
13 × 27 = 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27
13 × 27 = 351
Conclusion:
Total Carrots is 351 carrots.
Answer:
0.097 is the probability that the entire batch will be rejected
Step-by-step explanation:
The total number of CDs = 6500
Number of defective CDs = 110
Number of good CDs = 6500-110 = 6390
Out of this batch, 6 are randomly selected, then the probability that the entire batch is rejected is
1 – [probability of accepting the entire batch]
1 – [6390/6500 * 6389/6499*6388/6498*6387/6497*6386/6496*6385/6495]
= 0.097
X^2+12x+6=0 subtract 6 from both sides...
x^2+12x=-6 halve linear coefficient, square it, and add it to both sides...
x^2+12x+36=30 now the left side is a perfect square...
(x+6)^2=30 take square root of both sides...
x+6=30^(1/2) subtract 6 from both sides...
x=-6-30^(1/2) and -6+30^(1/2)
