1-Jace receives a shipment of 700 oranges.He randomly selects 25 oranges to weigh.In that sample, 2 oranges weigh 5 ounces.How m
Nat2105 [25]

Answer: 56 oranges

Step-by-step explanation:

In a sample of 25 oranges, 2 oranges weigh 5 ounces.

Proportionally represented, that would be:

= 2 / 25

Assuming the 25 is representative for all 700 oranges, the number of oranges that can be expected to weigh 5 ounces from the shipment is:

= Proportion of 5 ounces oranges from sample * Total number of oranges

= 2/25 * 700

= 56 oranges

Its not telling me how to do this, please help
kenny6666 [7]

Step-by-step explanation:

Actually, it tells you exactly what to do.

First, translate, i.e., move over, the coordinates up by 3:

(1, 4)\rightarrow (1+3, 4+3) = (4, 7)

Then reflect this point about the x-axis and to do this,

(x, y) \rightarrow (x, -y)

(4, 7) \rightarrow (4, -7)
