Answer: -14 degrees F
Explanation:
Draw a vertical number line. Plot -3 on that line. Then move down 11 units to arrive at -14. Think of it like being in basement level 3 of a building, going down 11 floors, to get to basement level 14.
2 × 3 = 6
6 squared = 36
36 + 3 = 39
Hope this helps!
Answer:
1st, 2nd and 6th options
Step-by-step explanation:
Given
- x + = 6x ( multiply through by 6 to clear the fractions )
4 - 6x + 1 = 36x ← option 1 will have the same solution set
----------------------------------------------------------------------
Adding the 2 fractions on the left side gives
+ - x = 6x , that is
- x = 6x ← option 2 will have the same solution set
------------------------------------------------------------------------
From
4 - 6x + 1 = 36x ( add 6x to both sides )
5 = 42x ← option 6 will have the same solution set
Answer:
Reece log 54 miles
Step-by-step explanation:
The ratio of miles Reece runs to miles Samuel runs is 2 to 3.
Samuel logs 81 miles
the ratio 2 to 3 means that if Reece ran 2 miles Susan would run 3 miles, so Reece runs with respect to Susan is 2/3
R = Miles Reece runs
R = 2/3 * 81mi
R = 54mi
Reece log 54 miles
Answer:
We can be 95% confident that consumers spend between $4.04 and $15.96 less at Store A than the consumers spend at Store B.
Step-by-step explanation:
Confidence Intervals give an estimate as range of values for a statistic concerned at a <em>confidence level</em>.
In this case the statistic is the mean difference between Store A and Store B purchase amounts and the confidence level is 95%.
Confidence Interval can be calculated using M±ME where
- M is the sample mean difference between Store A and Store B purchase amounts
- ME is the margin of error from the mean
