Answer:

They do not run at the same rate because Jada ran at a rate of .150km per min, while Andre ran at .133333 km per minute.

Step-by-step explanation:

Andre ran : 2km/15min = .133333km per min

Jada ran: 3km/20min=.150km per minute

.150>.1333, so Jada ran at a higher rate of kilometers per minute.

The Box-and-Whisker Plot represents the ages of 40 people who responded to a telephone survey.
kondaur [170]

Answer:

'A' is true; theoretically, 50% of the data items reside between the first and third quartiles (40 and 67.5)

Step-by-step explanation:

Range is 84-28 which is 56

Median is 51

1.5 x Interquartile Range (IQR) = 1.5(67.5-40) which equals 41.25

Q1 is 40

Q1 - IQR = -1.25

Low outliers are below -1.25 - 41.25; there are not data items below -42

How do you work out this equation
Gnom [1K]

Answer:

x is equal to negative one, and y is equal to negative four.

Step-by-step explanation:

You can do this by solving one of the equations by either x or y, then substituting it into the other.  Let's solve the second one for y:

2y = 3x - 5\\y = \frac{3x - 5}{2}

Now we'll substitute that into the first equation:

9x - 2y = -1\\9x - 2(\frac{3x - 5}{2}) = -1\\9x - 3x + 5 = -1\\6x + 5 = -1\\6x = -6\\x = -1

So we now know that x is equal to -1.  We can simply substitute that into one of the original equations to find y:

2y = 3x - 5\\2y = 3(-1) - 5\\2y = -3 - 5\\2y = -8\\y = -4

We now know that x is equal to -1, and y is equal to -4.  We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:

9x - 2y = -1\\9x - 2(-4) = -1\\9x + 8 = -1\\9x = -1 - 8\\9x = -9\\x = -1

So we know that our answer is correct.

What is the inverse of the following conditional statement?
Lady bird [3.3K]

Answer:

D) If an integer is NOT even then it is NOT divisible by 2.

Step-by-step explanation:

An inverse if/then statement is like an opposite statement. So the statement "if A happens, then B will happen" the opposite would be like saying "if A does NOT happen then B will NOT happen." Hopefully that makes sense :)
