Amy rolls a number cube ten times and gets 3 four times! If she rolls the number cube 240 times, how many times should she get a

Answer:

Amy should not use her previous luck of rolling a 3 four times because theoretical probability remains the same even after an event favoring one side has occurred by chance.

Step-by-step explanation:

Assuming that this number cube has 6 sides, there is only 1 side that has a 3 on it. For this reason, every time the cube is rolled there is a 1 in 6 chance that the number will be a 3. If she rolls the number cube 240 times, 1 out of 6 rolls would be a 3. This means that 240/6 equals the number of times she would get a 3. Moreover, Amy would role the number 3 on 40 different times after rolling the cube for a total of 240.

Factorise completely 3m^2-48​
Helen [10]

Answer:

3 (m^2 - 16)

Step-by-step explanation:

factoring means taking out a common multiple of all the terms in the expression

in this case, if you multiply 3 and m^2, 3 and -16, you would get 3m^2-48​

so you take the three and put it outside of the parenthesis that contains the factored terms

this leaves you with 3 (m^2 - 16)

Answer:

The y-intercept is at the point (0, 9).

Step-by-step explanation:

WE have the y intercept when x = 0:

-7(0) - 5y = -45

-5y = -45

y = -45/-5 = 9.

What is the area of a sector with a central angle of 2π/9 radians and a radius of 16.7 ft?
Y_Kistochka [10]

Answer:

Area of the sector is 97.30 square feet.

Step-by-step explanation:

The area of the sector is given by

A=(\frac{\theta}{2})r^2

Plugging the known values in this formula to find the area of the sector

A=(\frac{2\pi/9}{2})(16.7)^2\\\\A=\frac{2\pi}{18}\cdot16.7^2

Use the value of π as 3.14

A=\frac{2\cdot3.14}{18}\cdot16.7^2

Simplifying, we get

A=97.3016

Rounded to the nearest hundredth, we get

A=97.30
