Question about The Learning Company Achieve! Math & Science Grades 1-3 (381933) for PC, Mac

When there is not enough rain, Friendly Farms needs to supplement with irrigation. The profit when there is sufficient rain during the maximum growth period is $4000 per acre. If it does not rain during this period, the profit is only $1600 per acre. Using this information, what profit per acre, on average, can Friendly Farms expect to make? What math strategy do I use to solve this problem?

First, you need to get the probability of the two events - not enough rain and enough rain.

The probability of not enough rain is 1 less the probability of enough rain.

Supposing that the probability of not enough rain is 0.70, then the probability of enough rain is 0.30.

Therefore to get the profit per acre, you multiply these probabilities with their profits per acre. Hence,

$4000 * 0.30 + $1600 * 0.70 = $2,320 is the average profit per acre.

The above method uses the mathematics principle of the weighted expected returns.

I hope this helps.

3 (6c + 5) + 2 (c + 4) now multiply into the brackets

= 18c + 15 + 2c + 8 now gather like terms

= 20c + 23 and that's it

= 18c + 15 + 2c + 8 now gather like terms

= 20c + 23 and that's it

The Egyptians believed frogs to have been formed from mud and
water, a belief that seems to have materialized as a result of rivers flooding
during the rainy season, at which time frogs reproduced in such quantities that
thousands of tiny frogs and toads invaded walkways and public areas; they even
entered private homes and in general were regarded as pests.
This phenomenon was dubbed "Frog Rain", because such occurrences
always happened after the first heavy rains of the season.
As such frogs became associated with weather predictions because they
would begin croaking just before rains.

It's a municipality with a population of about 60 thousand people, with an ocean to the south, and other municipalities on the other three sides. The climate is "Pacific Rain Forest", i.e., some snow during winter, but lots and lots of rain.

Here are just some answers I was able to search through the web.

That's the most important part. But read the entire section from this site,

- First, the world is built of shape and space, and geometry is its mathematics.
- Second, informal geometry is good preparation. Students have trouble with abstraction if they lack sufficient experience with more concrete materials and activities.
- Third, geometry has more applications than just within the field itself. Often students can solve problems from other fields more easily when they represent the problems geometrically.
- And finally-a related point-many people think well visually. Geometry can be a doorway to their success in mathematics.
- because of geometry their so many beautiful buildings

I don't think you can learn algebraic equations in a low grade. It is simple enough if you just solve by hand or by a calculator.

Solve for y, when x = 1325.

x - 450 = y

1325 - 450 = y

y = 875

Following formula we can use.

S=P(1+RT)

WHERE S =INVEST AMOUNT+PROFIT

P=INVEST AMOUNT

R= RATE OF RETURN

T=TIME IN YEARS

EX : (300+x) = x(1+(5.4/100)*1)

(300+x)*100 = 105.4x

x=30000/5.4

x=5555. 4

S=P(1+RT)

WHERE S =INVEST AMOUNT+PROFIT

P=INVEST AMOUNT

R= RATE OF RETURN

T=TIME IN YEARS

EX : (300+x) = x(1+(5.4/100)*1)

(300+x)*100 = 105.4x

x=30000/5.4

x=5555. 4
