assume that random guesses are made for 8 multiple choice questions on an SAT test, so that there are n=9 trials, each with prob

melamori03 [73]

Answer:

$P(x$

Step-by-step explanation:

If we call x the number of correct questions obtained in the 9 attempts, then:

x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.

So, the p of x successes has the following formula.

$P(x) =\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}$

Where:

n = 9

p = 0.6

We are looking for P(x<4)

By definition:

$P(x$

Then:

$P(x\leq3)=\sum_{x=0}^{3} \frac{9!}{x!(9-x)!}*(0.6)^x(1-0.6)^{9-x}$

$P(x\leq3)=0.0994$

Answer: 1000 HK dollars has the same value as 188.15 NZ dollars.

Step-by-step explanation:

We know that:

1 US dollar = 7.76 HK dollars

1 US dollar = 1.46 NZ dollars.

We have 1000 HK dollars, and we want to know the value in NZ dollars.

First, let's rewrite the 1000 HK dollars in US dollars.

Here we use the relation:

1 US dollar = 7.76 HK dollars

Then:

1 = (1 US dollar/7.76 HK dollars)

Then we can write:

1000 HK = (1000 HK)*1 = (1000 HK)*( (1 US /7.76 HK ))

1000 HK = (1000 HK/7.76 HK)* 1 US = 128.87 US

1000 HK = 128.87 US

Now we can use the relationship:

1 US = 1.46 NZ

Then:

1 = (1.46 NZ)/(1 US)

So we can rewrite:

128.87 US = (128.87 US)*1 = (128.87 US)*( (1.46 NZ)/(1 US))

128.87 US = (128.87 US/1 US)*1.46 NZ = 188.15 NZ

Then:

1000 HK = 128.87 US = 188.15 NZ

So we can conclude that 1000 HK dollars has the same value as 188.15 NZ dollars.
