What is the result when the number 60 is increased by 60%

Mathematics

otez555 [7]3 years ago
7 0

Answer:

96

Step-by-step explanation:

A quick but accurate way to approach this question would be to multiply 60 by 1.60.  We get 1.60(60) = 96.

Note that 1(60) = 60, and that 0.60(60) = 36, and that 60 + 36 = 96.  The earlier method is faster.

KiRa [710]

Answer:

8 Hours

Step-by-step explanation:

Well, it normally takes her 8 hours but you subtract 2 hours now. So she works for 6 hours and the other clerk 10.

6+10=16

Then you divide 16 by two because you are dividing the amount of work they must complete.

16/2=8

I believe it will take them a total of 8 hours.

According to a recent study of 7335 young people in the US, 30% had been arrested for a crime other than a traffic violation by
victus00 [196]

Answer:

a) Statistic.

b) The population proportion is expected to be between 0.29 and 0.31 with a 94% degree of confidence.

Step-by-step explanation:

a) The proportion of 30% is a statistic, as it is a value that summarizes data only from the sample taken in the study from USA Today. Other samples may yield different proportions.

b) We can use the statistic to estimate a confidence interval for the parameter of the population.

The standard error for the proportion is calculated as:

\sigma_p=\sqrt{\dfrac{p(1-p)}{N}}=\sqrt{\dfrac{0.3\cdot 0.7}{7335}}=\sqrt{2.83\cdot10^5}= 0.00535

The margin of error is 0.01. We can use this value to determine the level of confidence that represents.

The formula for the margin of error is:

E=z\cdot \sigma_p=0.01\\\\z\cdot 0.0535=0.01\\\\z=1.87

This z-value, according to the the standard normal distribution, corresponds to a confidence interval of 94%.

The interval for this margin of error is:

p-E\leq \pi \leq p+E\\\\0.30-0.01\leq \pi \leq 0.30+0.01\\\\0.29\leq \pi \leq 0.31

Then, we can conclude that the population proportion is expected to be between 0.29 and 0.31 with a 94% degree of confidence.

if you subtract the least integer from the greatest integer and divide the difference by 3 the quotient is 5
vodomira [7]
Let a and b be integers and b>a, then we can say:

(b-a)/3=5  now multiply both sides by 3

b-a=15

b=15+a

So there are infinitely many pairs of integers that satisfy the conditions given in the problem. For any value a, b will be 15 units greater.

Need help with number 66 plz. Math.
Wittaler [7]

Let l be the length of the I-476. We know that the 22 miles long portion is one sixth of the total. So, if we divide the total by six we get 22:

\dfrac{l}{6} = 22

Multiply both sides by 6:

l = 22\cdot 6 = 132
