Since the average is the sum divided by the count, the sum is the average times the count.
So the sum of the weights of the watermelons is 10(4.3)=43 pounds.
The sum of the weights of the pumpkins are 5(3.4)=17 pounds
The sum of the weight of the fruits is 43+17=60 pounds
Dividing by 15 fruits gives an average item weight of 60/15 = 4 pounds
In triangle, ABD,
AD²= AB²+BD²
AB² = AD²-BD²
AB² = 18²-9² = 324-81 = 243
AB = √243
In triangle, ABC,
AC² = AB²+BC²
AC² = (√243)²+(13)²
AC² = 243+169
AC = √412
AC = 20.29
Answer:
y = -300x
Step-by-step explanation:
The y-intercept passes through 0, in this case, we don't have to include the y intercept to the equation. The slope is -300, or vertical/horizontal (rise/run, the formula for finding slope <<) We just include the slope if there is no y intercept. So, y = -300x is the equation!
