Answer:
A 0.8t equal 10000 bacteria B. 160,000 bacteria C. 2.5 minutes
Step-by-step explanation:
(20000-10000)/t equal to (100,000-10000)/(t+10)
Answer:
the piece of fabric and ribbon are the same length. in that case, its 0
Step-by-step explanation:
Answer:
B -0.104
Step-by-step explanation:
Step 1: Write the formula for correlation
r = total xy
√Total x² x Total y²
Step 2: Make a table to calculate all values
Table is attached in the picture below
Step 3 : Solve
Mean of X = Total X/ Total number of X
= 507/12
= 106.33
Mean of Y = Total Y/ Total number of Y
= 1276/ 12
= 42.25
r = total xy
√Total x² x Total y²
r = -352.05/ √3656.25 x 3122.66698
r = -0.104
-0.104 is negative
This negative correlation means there is an inverse correlation between variables.
The factored form of 9x^2 + 12x + 4 is:
(3x+2)(3x+2) or (3x+2)^2
When you are rounding to the nearest tenth, you only look at the number right to the tenths which in this case is 5, so you round up the 6 to a 7, which will be.
8.7
