the question in English
Mateo will reproduce a photo measuring 5 cm per side on a scale of 3/4
How much will the square side of the copy measure?
Will the size of the copy be larger or smaller than the original?
we know that
the scale factor is equal to 
Let
x----------> the original length side
y--------> the copy length side
we have that
substitute the values
therefore
<u>the answer Part a) is </u>
the length side of the copy measure is 
Part b)
we know that
the size of the original photo is------> 
the size of the copy is------> 
so
therefore
<u>the answer part b) is</u>
The size of the copy be smaller than the original
The formula of a midpoint:
We have:
Substitute
<h3>Answer: (-2, -4)</h3>
The unit rate means we need to find it per one soda can. So, 32/32 is one. We do the same to $3.99. $3.99/32 is about 13 cents.
Unit rate is: 13 cents per soda can
Answer:
Step-by-step explanation:
The question says,
A roulette wheel has 38 slots, of which 18 are black, 18 are red,and 2 are green. When the wheel is spun, the ball is equally likely to come to rest in any of the slots. One of the simplest wagers chooses red or black. A bet of $1 on red returns $2 if the ball lands in a red slot. Otherwise, the player loses his dollar. When gamblers bet on red or black, the two green slots belong to the house. Because the probability of winning $2 is 18/38, the mean payoff from a $1 bet is twice 18/38, or 94.7 cents. Explain what the law of large numbers tells us about what will happen if a gambler makes very many betson red.
The law of large numbers tells us that as the gambler makes many bets, they will have an average payoff of which is equivalent to 0.947.
Therefore, if the gambler makes n bets of $1, and as the n grows/increase large, they will have only $0.947*n out of the original $n.
That is as n increases the gamblers will get $0.947 in n places
More generally, as the gambler makes a large number of bets on red, they will lose money.
5.250
To change a fraction to a decimal fraction divide the numerator by the denominator.
that is 21 ÷ 4 = 5.250 ( to 3 decimal places )
