Answer:

2

Step-by-step explanation:

(4 - 5) - (13 - 18 + 2)

According to PEMDAS, we should simplify the parentheses first.

= (-1) - (-3)

When you subtract a negative number, you are actually adding.

= -1 + 3

Now, add.

= 2

Hope this helps!

Find the distance between points A (10,-1) and B (-2,5). Round to the nearest tenth
bija089 [108]

Answer:

<h2>The answer is 13.4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (10,-1) and B (-2,5)

The distance is

|AB|  =  \sqrt{ ({10 + 2})^{2} +  ({ - 1 - 5})^{2}  }  \\  =  \sqrt{ {12}^{2}  +  ({ - 6})^{2} }  \\  =  \sqrt{144 + 36}  \:  \:  \:  \:  \:  \:  \:   \\  =  \sqrt{180}  \\  = 6 \sqrt{5}  \:  \:  \\  =13.416407

We have the final answer as

<h3>13.4 units to the nearest tenth</h3>

Hope this helps you

What is the chance of rolling a 4 with a single die three times in a row
kumpel [21]

The key thing to remember when you're working a problem like this is that
the cube has no memory ... it doesn't know what happened on the last roll,
so the chance of any particular thing happening on the 2nd roll, or on the
100th roll, is the same as it was on the first roll.

Probability of success = (number of ways to succeed) / (total possibilities)

Number of ways for a 4 to come up . . 1
Total possible results of the roll . . . . . 6

Probability of rolling a 4 . . . . . 1 / 6 .

Probability of rolling two 4s . . . (1/6) x (1/6)

Probability of rolling three 4s . . (1/6) x (1/6) x (1/6) =  1/216 = about <em>0.46%</em> .

For this question, I would first see what one child is equal toby divide the children by the percentage.
15÷3= 5
Each child is worth 5%. If you know each child is worth 5%, and the total number of students are 100%, then you can divide.
100÷5= 20
There are 20 students in the class. To make sure our answer is right, we can check to see if 3 students are 15 percent.
3÷20= .15×100= 15
So yes, there are 20 students in the class.
