IF you are solving for d:
isolate the D, do the opposite of PEMDAS.
-d/6 + 12 = -7
(subtract 12 from both sides)
-d/6 + 12 (-12) = -7 (-12)
-d/6 = -19
(multiply 6 to both sides)
-d/6(6) = -19(6)
-d = -19(6)
-d = -144
-d/-1 = -144/-1
d = 144
hope this helps
Answer:
10g/cm^3
Step-by-step explanation:
Density is calculated by dividing the mass over volume.
d = m/v ( where d is density,
m is mass and
v is volume).
In this question, the value for volume is unknown as we were only given length.
STEP 1:
so we find volume first by using the length of side given.
Volume of a cube = (length of side )^3
volume = (2cm)^3 , volume = 2cm x 2cm x 2cm = 8cm^3
STEP 2:
we put the value for volume into the density formula'
d = mass / volume
d = 80g / 8cm^3
d = 10g/cm^3
Answer: the known variable; the to-be-predicted variable
Step-by-step explanation:
In statistics, linear regression is a technique to model the relationship between two variables ( one independent and other dependent).
It requires some previous data to plot a best fit line.
It is used to predict the values for dependent variable for each independent variable.
Here, independent variable = known variable and dependent variable = is to be predicted
Hence, Linear regression describes the extent to which <u>the known variable</u> predicts <u>the to-be-predicted variable</u>.
Answer:
48 people.
Step-by-step explanation:
The sequence is 3 5 7 ...
The common difference is 2 so by the 7th stop 6 lots of people have boarded and the total is:
3 + 5 + 7 + 9 + 11 + 13 = 48 people.

Answer:
D) 90 inches
Step-by-step explanation:
There are 36 inches in a yard (3 feet)
To find how many inches, multiply the numbers.
2.5 × 36
90 inches
