Suppose an ATM PIN must consist of 6 numbers from the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, with repeats allowed. For example, an acceptable PIN could be 955123.
1. How many possible ATM PINs are possible?
2. If someone had one attempt to guess an ATM PIN, what is the probability they would guess correctly with one attempt?
Answer:
1) the no. of possible pins are 6×5×4×3×2×1
=720
2) the probability is 1/720

Answer:
[tex] 2\sqrt{3} [/tex]
Step-by-step explanation:
1. Expand the expression
[tex] \frac{6}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } [/tex]
2. To multiply the fractions, multiply the numerators and denominators seperately
[tex] = \frac{6 \sqrt{3} }{ \sqrt{3} \sqrt{3} } [/tex]
3. Calculate the product : when a square root of an expression is multiplied by itself, the result is that expression.
[tex] \frac{6 \sqrt{3} }{3} [/tex]
4. Reduce the fraction with 3 and the solution is :
[tex] = 2 \sqrt{ 3} [/tex]

What’s x = in this equation
Answer:
5m
Step-by-step explanation:
Applying Pythagoras theorem:
a² + b² = c² (where a is base length, b is the height and c is the hypotenuse of the right triangle)
3² + 4² = c²
c² = 9 + 16 = 25
c = x = [tex]\sqrt{25}[/tex] = 5
∴ x = 5m

a Find the sum of interior angle of the heptagon
Answer:
sum of the interior angles=900°
Answer:
900°
Step-by-step explanation:
To find any shape sum of interior angles ,
we use the formula,
(n-2)180°, where n is the number of sides
So for heptagon,
n=7
using formula,
(7-2)180°
=> 5(180)
=> 900°

Students in Ms. Bell’s geometry class created posters of geometric definitions. Which of the following is the most precise definition?
A. Parallel lines are lines that do not intersect.
B. A line segment is part of a line that has an endpoint.
C. Perpendicular lines are lines that intersect at a right angle.
D. An angle is formed by two lines, two segments or two rays in one plane.
Answer:
C
Step-by-step explanation:
D is missing 2 ideas.
An angle can be formed by a mixture of the types of figures quoted.An angle has common or shared endpoint.B: to me is unclear. A line does not have an endpoint. A ray does.
A: you need to mention that the lines are coplanar.
I think, brief though it is, C is the most complete and at the same time simplest choice.
