Answer:

1 1/3

Step-by-step explanation:

Use the formula m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}} to find slope.

Plug in the numbers:

m=\frac{4-(-4)}{3-(-3)}

Solve for the numerator and the denominator:

m=\frac{8}{6}

Simplify:

4/3

Slope is 1 1/3 or 1.333

valina [46]

The question is incomplete, the complete question is;

The radius of the sphere is 10 units.What is the approximate volume of the sphere? Use π = 3.14 and round to the nearest whole cubic unit. cubic units

Answer:

4187 cubic units

Step-by-step explanation:

According to the question;

radius (r) = 10 units

 π = 3.14

Volume of a sphere = 4/3*π*r^3

Substituting values;

V = 4/3*(3.14)*(10)^3

V = 4186.67 cubic units

V = 4187 cubic units (To the nearest whole cubic unit)

Answer:

There are (63) combinations. The notation means "six choose three". Out of six items (flavors) choose three.

(nk)=n!k!(n−k)!.

(63)=6!3!3!.

Think of it this way. There are 6 ways to choose a flavor. Once you choose, there are 5 ways to choose the next. After that, there are 4 flavors left. which is 6!/3!=6⋅5⋅4⋅3⋅2⋅13⋅2⋅1=6⋅5⋅4=120.

But, you could have chosen {chocolate,vanilla,strawberry} and you get the same combination as {vanilla, strawberry, chocolate} so we have to divide by 3!=3⋅2⋅1=6 to account for the order of choosing.

So the number of combinations of flavors is (63)=1206=20.
