Answer:
E is short for 10^x. The number that comes after the E is the power of 10.
So its 7.6*10^12
now that scientifically notation
For standard your gonna need to simplify that
so we know 10^12 is 1000000000000
Multiply the 7.6
7600000000000
hope I helped :)
Answer:
Yes
Step-by-step explanation:
If the diagonals are perpendicular, then the slope of AC will be the opposite reciprocal of the slope of BD.
The slope of AC is:
m = (3 − 3) / (6 − 0) = 0
The slope of BD is:
m = (0 − 6) / (3 − 3) = undefined
The opposite reciprocal of 0 is undefined, so the diagonals are indeed perpendicular.
Specifically, AC is horizontal and BD is vertical.
Answer:
The test statistic is -2.5
Yes, I can reject the null hypothesis at 5% significance level.
Step-by-step explanation:
Null hypothesis: The average number of sardines in a can is 9.75
Alternate hypothesis: The average number of sardines in a can is greater than 9.75
Test statistic (z) = (sample mean - population mean) ÷ sd/√n
sample mean = 9.75
population mean = 10
sd = 1
n = 100
z = (9.75 - 10) ÷ 1/√100 = -0.25 ÷ 0.1 = -2.5
The test is a one-tailed test. At 5% significance level, the critical value is 1.645
Conclusion:
Reject the null hypothesis because the test statistic -2.5 is less than the critical value 1.645
The correct answers are the x = 6 and x = 0.
In order to find this, we can follow the order of operations.
–4|–2x + 6| = –24
Divide by -4
|–2x + 6| = 6
Since it is now equal to a absolute value, we have to solve for the positive and negative versions of the final answer. Let's start with the positive.
-2x + 6 = 6
-2x = 0
x = 0
Now for the negative
-2x - 6 = -6
-2x = -12
x = 6
These would be your two answers.
Answer:
C.
Step-by-step explanation:
Answer:
(0,0) and (1,4)
Step-by-step explanation:
you want to have the same slope as
y=4,which is 4.
so(4-0)/(1-0)=4/1=4
The others do not have the same slope.
5 x 2 - 8
2 x 3 6
-------------- = -------- = 3
5 x 2 - 8 2
