Answer:

A: 4 / 24 (or 1/6) B: (24 - 3) / 24 = 21/24 (or 7/8) C and D: Theoretical probability for each number is 1/6 on each roll, and we expect 4 occurrences of each number, on average. 2 came up as expected. 6 came up 3/4 as often as expected. Or "Not-6" came up 21 instead of 20 times, slightly more often than expected.

Which pair of triangles can be proved congruent by the SAS postulate?
Olenka [21]
C. â–łADE and â–łEBA

Let's look at the available options and see what will fit SAS.

A. â–łABX and â–łEDX
* It's true that the above 2 triangles are congruent. But let's see if we can somehow make SAS fit. We know that AB and DE are congruent, but demonstrating that either angles ABX and EDX being congruent, or angles BAX and DEX being congruent is rather difficult with the information given. So let's hold off on this option and see if something easier to demonstrate occurs later.

B. â–łACD and â–łADE
* These 2 triangles are not congruent, so let's not even bother.

C. â–łADE and â–łEBA
* These 2 triangles are congruent and we already know that AB and DE are congruent. Also AE is congruent to EA, so let's look at the angles between the 2 pairs of congruent sides which would be DEA and BAE. Those two angles are also congruent since we know that the triangle ACE is an Isosceles triangle since sides CA and CE are congruent. So for triangles â–łADE and â–łEBA, we have AE self congruent to AE, Angles DAE and BEA congruent to each other, and finally, sides AB and DE congruent to each other. And that's exactly what we need to claim that triangles ADE and EBA to be congruent via the SAS postulate.

What is the equation of a line that passes through point r(−4, −3) and has a slope of 7?
Firlakuza [10]
Slope m= 7
From general equation of a line;
y=mx+c
y=7x+c

Finding value of c by replacing for;
y=-3
x=-4
-3=7*(-4)+c
-3=-28+c
c=25
y=7x+25

Express 16 = 2x as a logarithmic equation.
Dmitrij [34]
If you meant
16=2ˣ then
remember
y=a^x translates to log_ay=x

so
16=2^x translates to log_216=x

What do you know about Scientific Notation
Helga [31]

Answer:

Scientific notation is a way of expressing, and handling, a mathematical expression used to represent a decimal number between 1 and 10 (multiplied by ten), so large numbers can be made with using less digits. An example would be writing 4 x 10³ for 4,000.
