Marco is interested in the number of penguins who live on a particular ice floe. He decides to take an aerial photo of
the floe and create a 20 by 20 grid on the photo. He randomly selects 3 cells and counts the number of penguins in
each. He then finds the mean number of penguins for those 3 cells. Marco repeats this process for a total of 50
samples and makes a dotplot of the 50 means. This graph is an approximation of
O stratified random sampling.

I NEED HELP! I’m on a test!!
Answers
Answer:
=38
Step-by-step explanation:
Use substitution :3
4(8)+6=38
substitute x to 8 then calculate!
There you'll get your answer.
the required value of expression 4x + 6 is 38 when x = 8.
If x = 8, what is the value of 4x + 6 to be determine.
In mathematics, it deals with numbers of operations according to the statements.
The equation is the relationship between variables and is represented as y = 4x +8 is an example of a polynomial equation.
Here, the expression is given as,
y = 4x + 8
now we have x = 8, put this x in y
y = 4(8) + 6
Solving the equation using the PEMDAS rule of mathematics
1St open the parenthesis of 8 then multiply this 8 by 4.
y = 4*8 +6
y = 32 + 6
Now adding 32 and 6 will give 38
y = 38
Thus, the required value of expression 4x + 6 is 38 when x = 8.

Answers
Answer:
I think it’s true.
Step-by-step explanation:
The line best fit has been an estimate and cannot be calculated has been True.
The line best fit can be explained as the line formed by the adjoining of the majority of the points in a scatter plot, The best fit line can be in the shape of a straight line or a curve based on the points on the scatter plot.
The best fit helps in explaining the relationship between the variables in the scatter plot. The best fit has the maxima scattered point as the starting point of the line best fit.
The line best fit has been an estimated line about the straight-line equation fits the plot or not. Thus the measurement of line best fit has not been possible.
The given statement has been True.

2. Solve: 2p+4= - 50
Answers
2p + 4= -50
=> 2p = -50-4
=> 2p = -54
=> p = -54/2
=> p = -27
explanation: subtract 4 from both sides,
(4+(-4)) cancels out so you do (-50(-4)) which gives you (-54). Your equation should look like 2p=-54, then you divide 2 from both sides, 2p divided by 2, leaving the “p” variable by itself, while you also divide -54 by 2, which leave you with the final answer: p=-27
