Answer: Add 11 to the other side of the equation, giving you 81. Then, since x is square you are going to need to square root both sides (
this symbol). When you do that, you should get what x is! Let me know if you still need help!
Answer:
Two standard deviations
Step-by-step explanation:
The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;
one standard deviation lie within 68% of the mean
Two standard deviations lie within 95%
Three standard deviations lie within 99.7%
Hence, for the question given, 95% fall within 2 standard deviations of the mean
Answer:
<u>I'll give the choices by the number below:</u>
- 1. 45 miles. Taken from the table at day 0.
- 2. 39 miles. Given for Miguel.
- 3. Jose's. His goal has a greater value 45 > 39.
- 4. 5 miles a day. Change per day as per table.
- 5. 6.5 miles a day. Given.
- 6. Miguel's. Comparing 6.5 > 5
Answer:
-1
Step-by-step explanation:
1.)Reorder the terms:
7(8 + x) = 49
(8 * 7 + x * 7) = 49
(56 + 7x) = 49
2.)Solving
56 + 7x = 49
3.)Solving for variable 'x'.
4.)Move all terms containing x to the left, all other terms to the right.
5.)Add '-56' to each side of the equation.
56 + -56 + 7x = 49 + -56
6.)Combine like terms: 56 + -56 = 0
0 + 7x = 49 + -56
7x = 49 + -56
7.)Combine like terms: 49 + -56 = -7
7x = -7
8.)Divide each side by '7'.
x = -1
9.)Simplifying
x = -1
