The amount of gravel and the area it covers are examples of ratios.
A weight of 7 lb can cover 1 square foot, while 315 lb can cover an area of 45 square feet.
The relevant parameters are:
To find the number of pounds needed for 1 square foot , perform the following calculation:
Thus, we have:
Cross multiply
So, we have:
1 square foot, and 315 lb will encompass an area of

In theory, each letter has an equal chance of appearing since there are 15 of each. With 5 letters available, the total count is 75 balls, and each letter has a probability of being selected.
This suggests a theoretical frequency of , meaning on average, any specific letter should be drawn 250 times, so the answer is D.
The adjusted equation , indicating that the graph has been altered 4 units leftward and 6 units downward.
Clarification:
The parent equation is .
The transformed equation is .
Applying the function transformation rules, it's clear that the parent function has been modified into the function
.
According to the function transformation rules,
indicates shifting the function b units to the left.
Thus, the transformed function reflects a shift 4 units to the left.
Additionally, from the function transformation rules, we understand that,
indicates shifting the function b units downward.
Consequently, the transformed function mirrors a shift of 6 units downward.
In summary, the adjusted equation , shows the graph shifted 4 units to the left and 6 units downward.
