Answer:2.1

Step-by-step explanation:

To find the mean absolute deviation,

find the mean

find the difference between each data value and the mean

take the absolute value of each difference

find the mean of these differences

{2, 2, 5, 7, 10, 10}

Number of values = 10

Sum of values = 2+2+5+7+10+10= 36

Average = 36/10 = 3.6

Deviation from the mean =

Deviation. Absolute value

2-3.6 = -1.6. 1.6

2-3.6 =-1.6. 1.6

5-3.6=1.4. 1.4

7-3.6 =3.4 3.4

10-3.6 =6.4. 6.4

10-3.6 =6.4. 6.4

Sum of absolute values= 1.6 + 1.6+1.4++3.4+6.4+6.4= 20.8

mean absolute deviation

=20.8/10= 2.08

= 2.1 to the nearest tenth

What is the sum of the geometric series?
Dvinal [7]

Essentially this is asking you to sum the first three values of the geometric series that starts with i being 1 and has the rule of (8(\frac{1}{4})^{i-1}).

Since we must sum the first <em>three </em>geometric values we need to see what the value of i will be for the first three. The sigma notation shows us that the first i will be equal to 1. This means the second i is 2 and the third i is 3.

Knowing this you can plug in the corresponding i values into (8(\frac{1}{4})^{i-1}) and sum it all together

(8(\frac{1}{4})^{1-1}) + (8(\frac{1}{4})^{2-1}) + (8(\frac{1}{4})^{3-1})

(8(\frac{1}{4})^{0}) + (8(\frac{1}{4})^{1}) + (8(\frac{1}{4})^{2})

(8(1)) + (8(\frac{1}{4})) + (8(\frac{1}{16}))

(8) + (2) + (\frac{1}{2}))

10 + \frac{1}{2})

\frac{21}{2})

10.5

Shandra's parents put $1,500 in her bank account for college tuition. At an interest rate
gavmur [86]

Answer:

$6,427.99

Step-by-step explanation:

-We first find the effective annual interest rate as follows:

i_m=(1+i/m)^m-1\\\\=(1+0.0825/2)^2-1\\\\=0.084202

#We the use this rate to find the compounded amount after 18 years:

A=P(1+i_m)^n\\\\=1500(1.084202)^{18}\\\\=6427.99

Hence, the amount after 18 years is $6,427.99
