Answer:

There are 7 places shown in the table which are , →{Rome, Tokyo, Houston, Peru, Miami, Toronto, Canada}

Out of which 5 are cities.

City={Rome, Tokyo, Houston,Miami, Toronto,}=5

It is given that a,place from the city is chosen.

Probability of an Event

           =\frac{\text{Total Favorable event}}{\text{Total possible outcome}}          

Probability of selecting a city from 7 places in which 5 are cities

         P(A)=\frac{_{1}^{5}\textrm{C}}{_{1}^{7}\textrm{C}}\\\\P(A)=\frac{5}{7}\\\\P(A^c)=1-P(A)\\\\=1-\frac{5}{7}\\\\=\frac{2}{7}    

Option B

A parallelogram with sides of 6 and 10 has an area of 30. Find the measure of the small angle of the parallelogram.
dmitriy555 [2]
<span>A = 2 * (0.5ab) + b (10 - a) = ab + 10b - ab = 10b 

10b = 30√2; b = 3√2 

sin α = 3√2 / 6; α = 45 degrees 

Small angle: 45°; Large angle: 135°</span><span>

Virty [35]

Answer:

C) The centers will roughly be equal, and the variability of simulation A will be less than the variability of simulation B.

Step-by-step explanation:

The center for Simulation A and Simulation B will be roughly equal.

Overall Sample size of Simulation A = 1500 * 100 = 150000

Overall Sample size of Simulation B = 2000 * 50 = 100000

Since the sample size for Simulation A is greater, the variability of Simulation will be less.

Therefore, The answer is  C) The centers will roughly be equal, and the variability of simulation A will be less than the variability of simulation B.

PLEASE HELP!!! ASAP The function graphed approximates the height of a rock, in meters, x seconds after it falls from a cliff
nasty-shy [4]

The vertical numbers are the distance and the horizontal numbers are the time in seconds.

Look at where the line is located at the number 20.

It si between the 2 and the 3 on the horizontal line, but you can see it is closer to the 2 than it is the 3, so the time would be 2.2s
