Answer:
Thickness of each piece could be given by:
(Height of stack ÷ population of the stack)
(1.875 ÷ 500) = 0.00375
Step-by-step explanation:
Number of pieces of paper in a stack = 500
Height of the stack = 1.875
Diego's guess about the Thickness of each piece of paper = 0.015
Thickness of each piece could be given by:
(Height of stack ÷ population of the stack)
(1.875 ÷ 500) = 0.00375
Comparing Diego's guess with the calculated Thickness,
0.00375 is much lesser than 0.015
Hence, Diego is incorrect.

Answer:
Step-by-step explanation:
Both functions are linear, as the highest power of x is 1 in each case.
The function represented by the table has a slope of 6, since each unit increase in x results in a unit increase of 6 in y.
The function g(x) = 2x + 6 has a slope of 2.
The y intercept of f(x) is (0, -6), which we can read directly from the table.
The y int. of g(x) is 6, which can be read directly from y = 2x + 6.
g(x) has the greater y-intercept: +6 versus -6.

Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What percentage eat less than 10 pieces of candy on halloween
This is the pvalue of Z when X = 10.
has a pvalue of 0.2119
21.19% eat less than 10 pieces of candy on halloween
Answer:
x=9 and y=3
Step-by-step explanation:
Let's solve your system by substitution.
−4x+6y=−18 and y=−2x+21
Rewrite equations:
y=−2x+21;−4x+6y=−18
Step: Solve y=−2x+21for y:
y=−2x+21
Step: Substitute−2x+21foryin−4x+6y=−18:
−4x+6y=−18
−4x+6(−2x+21)=−18
−16x+126=−18(Simplify both sides of the equation)
−16x+126+−126=−18+−126(Add -126 to both sides)
−16x=−144
−16x
−16
=
−144
−16
(Divide both sides by -16)
x=9
Step: Substitute9forxiny=−2x+21:
y=−2x+21
y=(−2)(9)+21
y=3(Simplify both sides of the equation)
Answer:
x=9 and y=3
