Answer 1
Answer:

The probability that it will rain tomorrow and the football game will be postponed is 16% option (B) 16% is correct.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

It is given that;

There is an 80% chance of rain tomorrow and a 20% chance the football game will be postponed.

P(rain) = 80%

In decimal

P(rain) = 0.80

P(football game will be postponed) = 20%

In decimal:

P(football game will be postponed) = 0.20

The probability that it will rain tomorrow and the football game will be postponed:

P= P(rain)xP(football game will be postponed)

P = 0.80x0.20

P = 0.16

In percent; multiply it by 100

P = 0.16x100

P = 16%

Thus, the probability that it will rain tomorrow and the football game will be postponed is 16% option (B) 16% is correct.

Solve the following simultaneous equations using an appropriate method. a) 7x + 3y = 16
y = 4x - 1

b) 2x + y = 8
4x + 3y = 16

c) -3x + 2y = 19
4x + 5y = 13

d) -3x + 7y = 9
4x - 3y = 7

e) -4x + 5y = -7
x = 23 - 3y

f) y = -x
y = -2/5x - 1/5

Good evening ,

Look at the photo below for the answer.

:)

Answer:

a) x = 1 , y = 3

Step-by-step explanation:

a) 7x + 3y = 16

y = 4x - 1

or

3y + 7x = 16 ... (i)

y - 4x = -1 ... (ii)

Solving the simultaneous equation by substitution;

Equation (ii) tells us that y = 4x - 1

Substituting that in (i) gives;

3(4x - 1) + 7x = 16

12x - 3 + 7x = 16

19x = 16 + 3 = 19

x = (19)/(19) = 1

y = 4(1) - 1 = 3

Solve the systems of equations 3x-4y=-2 and -x+8y=-23

Answers

We can use the subtraction method in order to solve for this system. First, line up the equations:

3x - 4y = -2
x + 8y = -23
_________
Our goal is to essentially get rid of one of the variables. We can do so by multiplying the first equation by 2:

6x - 8y = -4
x + 8y = -23
__________
7x = -27

x = -27/7

Input x into one of the equations to solve for y:
-27/7 + 8y = -23
-27 + 56y = -161
56y = -134
y = -134/56
y = -67/28

(-27/7, -67/28)

Well, you wrote a list of 10 numbers, and
you called the list "Their answers".

If their answers are written as a list of 10 numbers,
