Answer: Hello mate!

In a fair die all the number have the same probability; 1/6

The probability of getting a 4 is the sides with the number 4 divided by the total amount of numbers in the dice, this is 1 divided by, the probability is 1/6

The probability o getting a number divisible by 3 is the number of numbers that are divisible by 3 divided by the total amount of numbers in the dice:

The numbers divisible by 3 are 3 and 6, and in the dice, there are 6 numbers in total, so the probability is 2/6 = 1/3

Solve for n: 21k – 3n + 9p > 3p + 12.
Katyanochek1 [597]
21k - 3n + 9p > 3p + 12....for n
-3n > 3p + 12 - 9p - 21k
n < (3p + 12 - 9p - 21k) / -3
n < -p - 4 + 3p + 7k
n < 2p - 4 + 7k <===

Anyone able to help with this question?
ELEN [110]

Answer:

This is trigonomentry

Use SOHCAHTOA

where :

s is sin

c is cos

t is tan

o is opposite (side)

h is hypotenuse (opposite of 90 degree angle)

and a is adjacent (side)

Sin = o/h

cos = a/h

tan = o/a

in this case we are looking for side BC which is the hypotenuse(h)

and we have the side adjacent(a) to angle 71

since we have a and h determine what to use SIN, COS, OR TAN?

we should use Cos

they‘ve given the angle so we should do this...

Cos71 = \frac{6.3}{h}

Cos71 = \frac{6.3}{BC}

now apply algebra...

6.3/cos71= BC

BC= 19.3507869666

BC = 19.4   (3SF)

3(2+7) - 9 x 7 = 3+8 x 2 x 2 - 4 = 16 ÷ 2 x 5 x 3 ÷ 6 = Please answer! ✨✨
Thepotemich [5.8K]

Answer:

At first, we have 3 expressions that are equal.

3(2+7) - 9 \cdot 7= 3+8 \cdot 2 \cdot 2 - 4

6+21 - 63= 3+32 - 4

-36=31

-36\neq 31

This is not true.
