Answer:
B) Falce
Step-by-step explanation:
Cylinder base is circle
Answer:
The first one
Step-by-step explanation:
Note the brackets means absolute value so the order of the first one goes like this
-1, 3/2, 2, 3, 3.5
Thus it's from least to greatest
Answer:
The 95% confidence interval is 
.
Step-by-step explanation:
The information provided is:
The critical value for 95% confidence level is:
Compute the margin of error as follows:
Then the 95% confidence interval is:
Thus, the 95% confidence interval is .
Answer:
B.
Step-by-step explanation:
sin∅ = opposite side over hypotenuse
cos∅ = adjacent side over hypotenuse
To find <em>x</em>, there are multiple ways:
tan72° = 6/x
x = 6/tan72°
cos72° = x/15
15cos72° = x
What we know:
quotient 9.2 x 10^6/ 2.3 x 10²
in quotients exponents are subtracted of they have the same base, for example 10^6 and 10² have the same base of 10
What we need to find: quotient 9.2 x 10^6/ 2.3 x 10²
9.2 x 10^6
-------------- = 4 x 10^4
2.3 x 10²
Here in this problem I divided 9.2 by 2.3 and got 4, since the solution was simple and clean meaning no repeated decimals I went ahead and divided the 10^6 by 10^2 and got 10^4.
Another method would be to expand both numbers then divide and do scientific notation again.
Remember to change to normal notation you move the decimal to the right using the number of the exponent.
9.2 x 10^6= 9200000
2.3 x 10²= 230
920000/230=40000
40000= 4 x 10^4 scientific notation
Use the method that is best for you or just know you can use either method to check your work.
