It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of ( $x_{1}$ ; $y_{1}$ ) and ( $x_{2}$ ; $y_{2}$ ) is $x_{1}$ * $x_{2}$ + $y_{1}$ * $y_{2}$ = (-6)*(-3)+4*6=18+24=42

To use an automated teller machine at a certain bank, you must enter a 3-digit code, using the digits 1 dash 9. How many 3-d

3241004551 [841]

Answer:

729 , 3- digit codes are possible

Step-by-step explanation:

To use an automated teller machine at a certain bank, you must enter a 3-digit code, using the digits 1 dash 9.

We need a 3 digit code using digits 1 to 9

so total of 9 digits are used

also repetition of digits are permitted

In a 3 digit code, first digit can be any number from 0 to 9

so 9 possible numbers for first digit.

since repetition is allowed so second and third digit also have any number between 0 to 9

3 digit code

------ , ------- , --------

9 possibilities for each place

---9--- , ----9--- , ----9----

9 *9 *9 = 729

so 729 , 3- digit codes are possible

Craig is practicing his baseball pitching he kept track of the speed of each of his throws yesterday,and made the histogram

Morgarella [4.7K]

Using it's concept, there is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

From the histogram, the number of pitches is given by:

1 + 5 + 3 + 4 + 1 + 2 = 16.

Of those, 2 were between 70 and 75 mph, hence the probability is given by:

p = 2/16 = 1/8 = 0.125.

There is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.
