Answer:
m =
Step-by-step explanation:
3x + 24y = 24
⇔ 3x + 24y - 3x = 24 - 3x
⇔ 24y = 24 -3x
⇔
Thus, is the slope of 3x + 24y = 24
Answer:
First find the 20% markdown price and subtract it from the original price. Then find 6% of the discounted price to get the tax. The tax plus the discounted price is the final price.
Step-by-step explanation:
Two significant Figures I believe because you want to go with the least amount of sig figs that are already in your problem which would be 2 in 7500 because the zeros are not significant
Given the information, we have a direct proportionality. Then, the proportions would be:
solving for x we get the following:
therefore, to paint 11 rooms, we will need 19 1/4 gallons of paint
Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699
