A computer is programmed to scan the digits of the counting numbers. For example, if it scans 1 2 3 4 5 6 7 8 9 10 11 12 13 then
Charra [1.4K]

I believed it is "401"

1-9 = 9 digits

10-99 = 90 which is 180

100-200 = 100 which is 300 digits

9+180= 189

1392-189= 1203

1200÷300=400 which 1200 digits

401 is the 1392 number scanned

Your parents will retire in 20 years. They currently have $300,000 saved, and they think they will need $1,450,000 at retirement
Tanya [424]
N=20 periods (years)
present value, P = 300,000
future value, F= 1450000
i=annual interest rate

F=P(1+i)^n
1450000=300000(1+i)^{20}
(1+i)^{20}=1450000/300000
(1+i)^{20}=29/6
(1+i)=(29/6)^{1/20}
i=(29/6)^{1/20}-1
i=(29/6)^{1/20}-1
=1.081963-1
=0.081963
=8.1963%

Answer: they need to earn 8.1963% or more to achieve their goal.

Given the follow statistics about scores on the last math test, what is the best description of the shape of the distribution?
julia-pushkina [17]

The shape of the distribution, is symmetric, is the best description of   statistics about scores.

<h3 /><h3>What is standard deviation ?</h3>

The standard deviation is the positive square root of the variance of this data set. Variance of a data set is the sum of squared differences of the data values from its mean to the total count of data values.

The given data in the problem is;

Mean = 78%

Standard deviation = 4%

Min = 64

Median = 78

Q1 = 72

Q3 = 84

Max = 99

The condition for the symmetric distribution is found as;

(\rm Q_2-Q_1)=Q_3-Q_2)

From the data we have;

(\rm Q_2-Q_1)=Q_3-Q_2)\\\\ (\rm Q_2-Q_1)= (\rm 84-78)= 6 \\\\ Q_3-Q_2)=(78-72) = 6 \\\\

So that , (\rm Q_2-Q_1)=Q_3-Q_2).

Hence, the condition of symmetry is followed.

To learn more about the symmetry, refer to the link;l

6. (5 points) Graph using two intercepts; show your work in finding the intercepts. 6x - 3y = 18
Setler [38]

Answer:

Divide both sides by 18. The new coefficients will be the reciprocals of the intercepts:

6x-3y=18 \rightarrow \frac6{18}x - \frac3{18}y = 1 \rightarrow \frac x3-\frac y6 =1 The two intercepts are then 3 and -6.

(I know, dividing by 3 both sides of the equations would have made the whole process way easier).

Alternatively, plug x = 0 to find the y intercept and y=0 to find the x intercept. Either way the graph will look something like the one I'm sketching on paint.
