Answer:

//

Step-by-step explanation:

Bill's answer is wrong because timesing 150 by 1.3 is increasing the number by 30%, not 3%

If he wanted to use this method, he would have ti times 150 by 1.03

Answer:

154.5

Step-by-step explanation:

Bill's method is wrong since 3% is equivalent to 0.03 or 3/100 and not 1.3 so this is where the mistake is. Moreover, Bill's method is not only wrong but also incomplete.

In order to increase 150 by 3% you will have to determine how much is 3% of 150 to have it increased by that specific amount.

<u>Calculations:</u>

150 x 0.03 = 4.5

Now that we know 4.5 is 3% of 150, we can add 4.5 to 150 to increase it by 3%.

150 + 4.5 = 154.5

I need help on this please help!
Licemer1 [7]

Answer:

(b)0.56

(c)0.38

Step-by-step explanation:

(a)

P(Ben Pass) =0.8

Therefore: P(Ben fails)=1-0.8 =0.2

P(Tom Pass) =0.7

Therefore: P(Tom fails)=1-0.7 =0.3

See attached for the completed tree diagram

(b)Probability that both will pass

P(both will pass)=P(Ben pass and Tom pass)

=P(Ben pass) X P(Tom pass)

=0.8 X 0.7

=0.56

(c)The probability that only one of them will pass

Since either Tom or Ben can pass, we have:

P(only one of them will pass)

=P(Ben pass and Tom fails OR Ben Fails and Tom Pass)

=P(Ben pass and Tom fails)+P(Ben Fails and Tom Pass)

=(0.8 X 0.3) + (0.2 X 0.7)

=0.24 + 0.14

=0.38

The slope of the line that contains the points (2, 11) and (0, 5 ) is 3. Which of the following equations represents this line?
taurus [48]

Answer:

C

Step-by-step explanation:

This is your current equation: y= 3x + b. Next, plug in one of your coordinates to the equation. It doesn't matter which one. I'm going to use the second ordered pair, so it should look like this: 5 = 3(0) + b. Multiply 3 and 0 to get 5 = b. So, your equation is y = 3x + 5. The correct answer is C. Hope this helped!

Ik what it is just helping out others 1+1
antiseptic1488 [7]

The question is asking what will we get if we add 1+1.

Let us use an example to understand this.

Example:

Suppose Amy has 1 ice cream and her brother Ruth has also got one ice cream.

Now if they both finished their ice creams, how many total ice creams were finished.

So we see that 1 and 1 add up to give two ice creams and so two ice creams are finished by them both.

Applying this to our question adding 1 and 1 gives us 2.

Answer : 1+1 =2
