400x4 is 1 mile so 400x8 is 2 miles so 3,200 is 2 miles minus 400 because she already walked that so the answer is 2,800
Answer:The value of the z-score tells you how many standard deviations you are away from the mean. ... A positive z-score indicates the raw score is higher than the mean average. For example, if a z-score is equal to +1, it is 1 standard deviation above the mean. A negative z-score reveals the raw score is below the mean average.
Step-by-step explanation:
Given:
The inequality is:
To find:
The solution for the given inequality and graph of it.
Solution:
We have,
Divide both sides by -20 and change the sign of inequality because inequality is divided by a negative number.
Therefore, the solution for the given inequality is .
All the value less than 4 are in the solution set. It means all the values on the left side of 4 are in the solution set.
Since 4 is not included in the solution set, therefore there is an open circle at 4.
The graph for the given inequality is shown below:
Step-by-step explanation:Step 1: Simplify both sides of the equation.
8(2x+3x+2)=−4x+148
(8)(2x)+(8)(3x)+(8)(2)=−4x+148(Distribute)
16x+24x+16=−4x+148
(16x+24x)+(16)=−4x+148(Combine Like Terms)
40x+16=−4x+148
40x+16=−4x+148
Step 2: Add 4x to both sides.
40x+16+4x=−4x+148+4x
44x+16=148
Step 3: Subtract 16 from both sides.
44x+16−16=148−16
44x=132
Step 4: Divide both sides by 44.
44x
44
=
132
44
