PIT_PIT [208]3 years ago
8 0

Answer:

412

Step-by-step explanation:

You have to follow PEMDAS and solve the problem carefully.

\frac{3+(2+8)^{2} }{4*(\frac{1}{2} )^{2} }  =\frac{3+(10)^{2} }{4*(\frac{1}{2} )^{2} } = \frac{3+100}{4*(\frac{1}{2} )^{2} } = \frac{103 }{4*(\frac{1}{2} )^{2} }

\frac{103 }{4*(\frac{1}{2} )^{2} } = \frac{103 }{4*(\frac{1}{16})} } = \frac{103 }{\frac{1}{4} } =\\103*4\\=412

A set of data is described as:
Savatey [412]

The group of measures which would lead to the provided conclusion is the range is 7, the mean of the data is 12, the median is 12 and the mode is 11.

Given that, the data is around 12. If another measurement were taken, it would probably be around 12.

We need to find which group of measures would lead to this conclusion.

<h3>What are the mean, median and mode of the data set?</h3>

The mean of the data is the average value of the given data. The mean of the data is the ratio of the sum of all the values of data to the total number of values of data.

The median of the data is the middle value of the data set when it arrange in ascending or descending order. The data is around 12 which suggests that the median is 12.

Median=12

The mode of a data set is the value, which occurs most times for that data set. The value which has the highest frequency in the given set of data is known as the mode of that data set.

Mean and mode is around the median. For this case, the mean of the data is 12 and the mode is 11.

Mode=11

Mean=12

Thus, the group of measures which would lead to the provided conclusion is the range is 7, the mean of the data is 12, the median is 12 and the mode is 11.

how would a enter a payment that was accepted with a 4 month, 8% note in a payment of a $4800.00 account
Anon25 [30]

Answer:

Enter a payment of 5192.52.

Step-by-step explanation:

Consider the provided information.

The payment is $4800 with a 4 month, 8% note.

The amount can be calculated as:

Amount=p(1+\frac{r}{m})^{mt}

Where <em>p</em> is money invested, <em>r</em> is annual interest rate, <em>t</em> is number of years and <em>m</em> is number of period.

Now substitute p = 4800 r = 0.08 and m = 4 in the above formula.

Amount=4800(1+\frac{0.08}{4})^4

Amount=4800(1+0.02)^4

Amount=4800(1.02)^4

Amount=4800(1.08243216)

Amount=5195.52\ approximately

Hence, enter a payment of 5192.52.
