You want one non-zero digit in front of the decimal. Count how many times the decimal must move to be behind the first non-zero digit. This is the power on the ten. If it moves to the left, the power is negative. If you must move it to the right it is positive.

I counted 7 moves to get to behind the 6.

The correct answer is 6.85 x 10-7 . Check the exponent of the 10 then move the decimal point that many places to the left.

ATM personal identification number (PIN) codes typically consist of four-digit sequences of numbers. Find the probability that i

oksian1 [2.3K]

Answer:

(a) 0.0001 or 0.01%

(b) 0.01 or 1%

Step-by-step explanation:

Since there are 10 possible numeric digits (from 0 to 9), and there is only one correct digit, there is a 1 in 10 change of getting each digit right.

The probability that if you forget your PIN, then you can guess the correct sequence

(a) at random:

$P=(\frac{1}{10})^4=0.0001=0.01\%$

(b) when you recall the first two digits.

$P=(\frac{1}{10})^2=0.01=1\%$

Complete the equation of the line whose slope is 5 and y intercept is (0,4)

irina1246 [14]

y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)

Solution:

Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)

The equation of line in slope intercept form is given as:

y = mx + c ---- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given that, slope = m = 5

y intercept is (0, 4)

So, c = 4

Substitute c = 4 and m = 5 in eqn 1

y = 5x + 4

Thus the equation of line is found
