The data below are the monthly average high temperatures for New York City. What is the five-number summary? 40, 40, 48, 61, 72,

yawa3891 [41]

Answer:

B) Sample minimum: 40, Sample maximum: 84

Q1: 45, Median: 63, Q3: 77

Step-by-step explanation:

The first step is to write the temperatures in crescent order:

40, 40, 42, 48, 54, 61, 65, 72, 76, 78, 84, 84,

The sample minimum is the lowest value = 40

The sample maximum is the highest value = 84.

Since there are 12 numbers, the sample median is the average between the 6th and 7th terms:

$M = \frac{61+65}{2}\\ M=63$

The first quartile is the average between the 3rd and 4th terms:

$Q_1 = \frac{42+48}{2}\\ Q_1=45$

The third quartile is the average between the 9th and 10th terms:

$Q_3 = \frac{76+78}{2}\\ Q_3=77$

Therefore, the answer is:

B) Sample minimum: 40, Sample maximum: 84

Q1: 45, Median: 63, Q3: 77

Distance formula

$\boxed{\sf \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

Now

#1

$\\ \tt\Rrightarrow AB=\sqrt{(3-3)^2+(-2-8)^2}=\sqrt{100}=10units$

#2

$\\ \tt\Rrightarrow OK=\sqrt{(5-7)^2+(-2+2)^2}=\sqrt{4}=2units$

#3

$\\ \tt\Rrightarrow LM=\sqrt{(-4-4)^2+(6+4)^2}=\sqrt{64+100}=\sqrt{164}\approx 13units$

#4

$\\ \tt\Rrightarrow PC=\sqrt{(5-2)^2+(1-3)^2}=\sqrt{9+4}=\sqrt{13}=3.2units$

#5

$\\ \tt\Rrightarrow QR=\sqrt{(-2+10)^2+(3-9)^2}=\sqrt{64+36}=\sqrt{100}=10units$

Suppose A and B represent two different school populations where A > B and A and B must be greater than 0. Which of the follo

lina2011 [118]

C. A^2 +B^2 will be the largest because we know that (a+b)^2 = a^2 +2ab +b^2

so than you check these other choices this ie the largest sure

Find the value to make the equation true<br><br> 1) ?/1 = 14/17

Serggg [28]

Answer:

14/17

Step-by-step explanation:

Find the value to make the equation true

1) ?/1 = 14/17

x : 1 = 14 : 17

x = 1 * 14 : 17

x = 14 : 17

x = 14/17

Which statements are true about exponential decay functions? Check all that apply. The domain is all real numbers. As the input

lorasvet [3.4K]

<h2>Answer:</h2>

The correct options are:

The domain is all real numbers.

The base must be less than 1 and greater than 0.

The function has a constant multiplicative rate of change.

<h2>Step-by-step explanation:</h2>

We know that the exponential function is given by:

$f(x)=ab^x$

where a>0 and b are constants.

Also, it represents a growth function if b>1

and a decay function if 0<b<1

where b is the base.

x belongs to whole of the real numbers( since the exponential function is well defined for all the real values of x.

Hence, the domain of the function is all the real numbers )

Also, the graph of a decay function decreases continuously i.e. with the increasing input value the output value decreases.

The exponential decay function always have a constant multiplicative rate of change i.e. b.
