A Professor at a University sent his phone number in a disorderly manner to his students. The disordered phone number was 640011

28454.
To know his real phone number, he gave the student the following conditions:

1. Eight (8) must come between two zeros (0's).

2.The first number after the first condition is met must not be an odd number and it must be greater than 5.

3. The seventh number must be 1.

4. The fifth and sixth numbers must be two numbers whose difference is 1 and the bigger number must come first.

5. The fifth and sixth numbers are greater than 2.

6. The ninth and tenth numbers are the same.

7. The eighth number is greater than the last number.

8. The phone number must be 11 digits.

Answer:

You get an perpendicular line through given point.

Step-by-step explanation:

In this method of drawing perpendicular line through given point,

you will draw an arc from given point R, so as to cut given line at A and B.

now ,length RA will be equal to length RB (radius of circle)

now, with length RA you will place compass at A and B to cut the arcs at point P (let) on other side of given line.Now, join PA and PB.  

The closed RAPB makes a rhombus and diagonal bisect perpendicularly in rhombus.

so you get an perpendicular line through given point.

You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Y
Luda [366]

Answer:

T = 4.541

Step-by-step explanation:

We don't have the standard deviation for the population, so we use the t-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 4 - 1 = 3

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 3 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.98}{2} = 0.99. So we have T = 4.541

9) v - 15 = -27 10) n + 16 = 9
Alik [6]

Answer:

9) v= -12  

10) n= -7

Step-by-step explanation:

9) v - 15 = -27

Add 15 from both sides

i.e. v - 15 + 15 = -27 + 15

v = -12

10) n + 16 = 9

Subtract 16 from both sides

i.e. n + 16 - 16 = 9 - 16

n = -7

Hope this helps!!!
