S_A_V [24]
The next day high temperature will be -18.7

The temperature will be considered as 'warmer' as the temperature increased and will be considered as 'colder' if the temperature decreased.
So, if the temperature for the next day is 5 degrees warmer, then it must be:

-23.7 + 5 = -18.7 Degree

​E: A randomly selected person accidentally killing a spider. ​F: A different randomly selected person accidentally swallowing a
alexdok [17]

Answer:

A. E cannot affect F and vice versa because the people were randomly​ selected, so the events are independent.

Step-by-step explanation:

Imagine a situation.

We probably live very far from each other

There is a probability that I kill a spider.

There is a probability that you accidentaly swallows a spider.

Or vice-versa.

If I kill a spider, i won't impact the probability that you accidentaly swallows a spider. So these events are independent, and the correct answer is:

A. E cannot affect F and vice versa because the people were randomly​ selected, so the events are independent.

Solve the following simultaneous equations 2x+5y=0 and 3x-4y=23
Elodia [21]

Answer:

x = 5, y = -2

Step-by-step explanation:

2x + 5y = 0 --- Equation 1

Equation 1×3: <u>6x</u> + 15y = 0 --- Equation 2

3x - 4y = 23 --- Equation 3

Equation 3×2: <u>6x</u> - 8y = 46 --- Equation 3

<em>We will be eliminating 6x from Equation 2. </em>

Equation 3-2: 6x - 8y - 6x - 15y = 46-0

-23y = 46

y = 46 ÷ -23

<u>y = -2 </u>

Substitute y = -2 into Equation 1:

2x + 5y = 0

2x + 5(-2) = 0

2x + (-10) = 0

2x - 10 = 0

2x = 10

x = 10 ÷ 2

<u>x = 5 </u>
