What is one way to remember that one-fourth is the same as 0.25? Next, explain how 1/2 is the same as 0.5.

1 answer:

4 0

One way to remember 0.25 = 1/4 is that a dollar is 1.00 and 0.25 can multiply 4 times into 1.00

One way to remember 0.5 = 1/2 is that 0.5 is half of a dollar

A taxi ride cost $1.25 plus $0.75 per mile. If the total cost of the trip is $12.50, how many miles did the passenger travel?

Talja [164]

Roughly 15 miles
d.15
$12.50 -1.25=11.25
11.25 divided by o.75= 15.0714286 so roughly 15 or 16ish

naomi's fish is 40 millimeters long. her guinea pig is 25 centimeters long. how much longer is the guinea pig than her fish

horrorfan [7]

Hi there!

The correct answer is 6.25 times.

This is how you get there:

1) First off, you are going to need to have the same unit (either cm or mm). I used millimeters for this problem. 25cm=250mm

2) This next part is very easy to get wrong. You need to figure out what you are dividing, and by what. Simply look at the problem. <span><em>"How much longer is the guinea pig than her fish?" </em>This shows what numbers you should be getting. The guinea pig is 250mm long, where the fish is only 40. This means that her guinea pig should be larger. 250÷40=6.25

If you did this problem the other way, you would've ended up with .16. If you put the sizes into perspective, you will notice that this is highly unlikely.

I hope that I have been able to simplify this problem for you!

Answer:

a) 0.0392

b) 0.4688

c) At least $39,070 to be among the 5% most expensive.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 29858, \sigma = 5600$
