Answer:

You just need to demonstrate that the expression is not equivalent. To do that, we just need to evaluate the expression with a specific number.

$\frac{3}{8}x+2 \neq \frac{3}{2}x+5$

For $x=0$ , we have

$\frac{3}{8}(0)+2 \neq \frac{3}{2}(0)+5\\2 \neq 5$

Notice that the answer is true because 2 is not equivalent to 5.

Therefore, the expression is actually non-equivalent.

Two athletic teams play a series of games; the first team to win 4 games is declared the overall winner. Suppose that one of the

kodGreya [7K]

Answer:

p=0.7103 (4-game series)
p=0.6480 (2-game series)

Step-by-step explanation:

Let X be the random variable equal the the first 4 straight wins. An overall win for the stronger team implies a negative binomial function with the parameters n=4, p=0.6:

$P(X=4)={{i-1}\choose {4-1}}0.6^40.4^{i-4},\ i=4,5,6,7$

#We find probabilities for the different values of i:

$P(X=4)={3\choose 3}0.6^4=0.1296\\\\P(X=5)={4\choose 3}0.6^40.4^1=0.2074\\\\P(X=6)={5\choose 3}0.6^40.4^2=0.2074\\\\P(X=4)={6\choose 3}0.6^40.4^3=0.1659$

Hence, probability of the stronger team winning overall is:

$=P(X=4)+P(X=5)+P(X=6)+P(X=7)\\\\=0.7103$

#Define Y as the random variable for winning 2/3 games.:

$P(Y=2)={1\choose 1}0.6^2=0.3600\\\\P(Y=3)={2\choose3}0.6^20.4=0.2880\\\\P(win)=0.2880+0.3600=0.6480$

Hence, probability of the stronger team winning in 2 out 3 game series is 0.6480

The stronger team has a higher chance of winning in a 4-game series(0.7103>0.6480)

Callie is starting a fruit basket business the largest basket has 30 pieces of fruit but the others have 12 pieces of fruit in e

Elis [28]

Answer:

In the first basket, Callie can make 15 apples, 10 oranges and 5 bananas.

In the second basket, she can make 12 apples, 8 oranges and 4 bananas and

in the third basket, she can make 9 apples, 6 oranges and 3 bananas.

Step-by-step explanation:

The largest basket contains 30 pieces of fruit. So, it contains

1/2 of 30 = 15 apples

1/3 of 30 = 10 oranges and

1/6 of 30 = 5 bananas.

The second and third baskets should contain at least 12 pieces and at most 30 pieces (since the largest basket contains 30 pieces). Also, the number should be divided by 2, 3 and 6. So, it must be a multiple of 6.

Clearly, the number of multiples of 6 between 12 and 30 are 18 and 24.

Hence, the second basket contains 24 pieces of fruits and it contains

1/2 of 24 = 12 apples

1/3 of 24 = 8 oranges and

1/6 of 24 = 4 bananas

The third basket contains 18 pieces of fruits and it contains

1/2 of 18 = 9 apples

1/3 of 18 = 6 oranges and

1/6 of 18 = 3 bananas.
