Answer:
y=-2/3x-3 is the equation in slope intercept form
Step-by-step explanation:
Hope this helps (:
We first calculate the z-score corresponding to x = 1075 kWh. Given the mean of 1050 kWh, SD of 218 kWh, and sample size of n = 50, the formula for z is:
z = (x - mean) / (SD/sqrt(n)) = (1075 - 1050) / (218/sqrt(50)) = 0.81
From a z-table, the probability that z > 0.81 is 0.2090. Therefore, the probability that the mean of the 50 households is > 1075 kWh is 0.2090.
Answer:
Step-by-step explanation:
I'm pretty sure that the equation for slope is y2 -y1
-----------
x2 - x1
Substitute in the info, and simplify to find the slope.
Answer:
We add the two fractions:
6 3/8 + 7 2/5 = 13 31/40 boxes of candy bars.
Answer:
Step-by-step explanation:
Check if the relationship is linear. Verify the difference between areas.
We can see the difference is not common.
It means we can exclude options B and C.
The remaining options are quadratic (A and D).
<u>Try the last column with option A:</u>
- 4813 = 45² + 1908
- 4813 = 3933
- False
<u>Verify the last option:</u>
- 4813 = 45² + 44*45 + 808
- 4813 = 4813
- Correct
We can check and confirm the other columns are correct as well.
