<span><span>Let x be the maximum speed of the plane and y be the speed of the wind

***Note: D = r*t or r = D/t***

x +y = 525mph |2100mi/4hr = 525mph

x -y = 350mph |2100mi/6hr = 350mph

2x = 875

x = 437.5mph, speed of plane. Wind speed is 87.5 </span><span>

Elza [17]

Answer:

I. x + y = -3 --> y = -x - 3

II. y = 2x


2x = -x - 3

3x = - 3

x = -1


y = 2*(-1) = -2

Using it's concept, the probabilities are given as follows:

19. A. 1/3.

20. F. 1/6.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, there are 1 + 1 + 3 + 4 + 3 = 12 papers. 4 have a score of 6, hence, in item 19, the probability is:

p = 4/12 = 1/3.

Which means that option A is correct.

2 papers have a score greater than 12, hence the probability in item 20 is given by:

p = 2/12 = 1/6.

Which means that option F is correct.

Jill says that 23/1000 can be written as 0.23. Which explains whether or not Jill is correct? A. Yes, Jill is correct. The fract
goldenfox [79]

Answer:

B. No, Jill is not correct, the fraction is equivalent to 0.023.

Step-by-step explanation:

The given fraction is \frac{23}{1000}

Observe that in the denominator there is 1000, which has three zeros after 1.

In changing the given fraction to decimal, there must be 3 significant digits after the decimal.

According to this option (b) is correct.

Moreover, when 23 is divided by 1000, we have

\frac{23}{1000}=0.023

But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.

Hence option (b) is correct,
