Experimental is the actual measured desiredoutcome/totaltrials

total trials=10+12+28=50

green is 28
so 28/50 or 14/25 is the experimental proablity of doing green

theoretical is desired/total possible,
total possible=total number of marbles=5+8+12=25
desired=8, so 8/25 is theoretical probablity of draing green



I would expect the experimental proabblity to approach the value of the theoretical proabblity, not sure why tho

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

Find the inverse function of <br><br> y=x^5+9
ollegr [7]

Answer:

\sqrt[5]{x - 9}

Step-by-step explanation:

y=x^5+9

To find inverse function make x the subject, first:

y=x^5+9

y - 9 = x^5

x = \sqrt[5]{y - 9}

y^{-1}  = \sqrt[5]{x - 9}

so  inverse function of y=x^5+9 is  \sqrt[5]{x - 9}

Solve for x: -5(2x-5)=8+(5-2x)<br><br> -4/3<br> -2<br> 3<br> 3/2
Nataliya [291]

Answer:

x =  \frac{17}{13}  = 1 \frac{4}{13}

Step-by-step explanation:

-5(2x - 5) = 8 + (5 - 2x)

-10x + 25 = 8 + 3x

-10x - 3x = 8 - 25

-13x = -17
