Answer:

<h2>35% No Rain Today</h2>

Step-by-step explanation:

0.65 plus p(complement) = one

P(Complement) = 1 minus 0.65 = 0.35 = 35%

I know this as well because I took the test with the same question

Answer:

no rain today = 35%

Step-by-step explanation:

In probability, the Complement Rule states that the sum of the probability of an event and its complement must = 1

i.e

P( Event) + P (Complement) = 1

In this sense, we can think of the complement of an event as the "not-event". I.e the event does not happen.

In our case, the event = "rain today",

hence the complement will be = "not rain today" (i.e no rain today)

using the formula above, we are given that P(rain today) = 65% = 0.65

hence

0.65 + P(Complement) = 1

P(Complement) = 1 - 0.65 = 0.35 = 35%

Answer:

1. =-6

2. =39

3. =-603

_________________________________________________

Explanation: This question's it's about the order of operations. It stands for p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right. (PEMDAS)

1. -4(3-1)+2

Do parenthesis first.

$(3-1)=2$

$-4*2+2$

Then do multiply left to right.

$-4*2=-8$

Add left to right.

$-8+2$

$8-2=6$

*Answer should be have negative sign.*

Answer: → $\boxed{=-6}$

______________________________________________________

2. 3⋅[(30−8)÷2+2]

Do parenthesis first.

$(30-8)=22$

$22/2+2$

Then divide left to right.

$22/2=11$

Add left to right.

$11+2=13$

Multiply left to right.

$3*13=39$

*Answer should be have positive sign.*

Answer: → $\boxed{=39}$

_____________________________________________________

3. 14(1-23)2+13

Do parenthesis first.

$(1-23)=-22$

$14(-22)*2+13$

Then, you multiply left to right.

$14(-22)=-308$

$-308*2=-616$

Add/subtract left to right.

$-616+13$

$616-13=603$

*The answer must be have a negative sign*

Answer: → $\boxed{=-603}$

one teacher want to give each student 4/5 of a slice of pizza, if the teacher has 4 slices of pizza, then how many students will

GuDViN [60]

Answer:

The answer is 5 students.

Step-by-step explanation:

This problem is a division problem.

To solve, divide 4 by 4/5.

There is a strategy for this- Keep, Change, Flip.

Keep the dividend like it is, which is 4 or 4/1.

Change the division to multiplication.

And flip the divisor- 4/5 to 5/4.

When you multiply, you should get 20/4.

Simplify by dividing 20 by 4.

20 divided by 4 is 5.

So the answer is 5 students
