4.2048 x 105 = 441.504
the standard form should be between 1 and 9 so the decimal point should be after the first digit (4)
it would look like this 4.41504 x 10 to the power of 2 because it moved back two places. hope it makes sense? (:
The missing X value equals 5. The triangle was dilated by a scale factor of 3 and 15 / 3 = 5.
Step-by-step explanation:
For an equation of form Ax + By = C, we are given A, B, and C.
The x intercept is when the line/equation is on the x axis, or when y=0.
Therefore, if we plug y=0 into the equation Ax+By=C, and anything multiplied by 0 is equal to 0, we can say that
Ax + 0 = C
Ax = C
divide both sides by A
x = C/A
Therefore, the x intercept is equal to C/A
Similarly, for the y intercept, or when the line is on the y axis (or when x=0), we have
A*0 + By = C
By = C
divide both sides by B
y= C/B at the y intercept
Answer: slope is 4, y intercept is ( 0,8) , x intercept is (-2,0)
Step-by-step explanation: graph the line using the slope and and y intercept.
Answer and Step-by-step explanation:
given:
Sample size is: n =5000
The sample proportion is: Ṗ = 2739 / 5000 = 54.78%
And the critical value of z for 99% confidence interval is
Z = 2.58
For a 99 % confidence interval we use formula:
Ṗ ± z√(Ṗ(1- Ṗ)/n)
By putting the given values in this formula:
0.54 ± 2.58√(0.54(1-0.54)/5000)
= 0.54 ± 0.018
This gives us upper confidence limit of
0.54 + 0.018 =0.558 = 0.54%
This gives us lower confidence limit of
o.54 – 0.018 = 0.522 = 0.53%
