Answer:

The variance is 129

Step-by-step explanation:

The variance of a binomial distribution is defined as

np(1-p)

where n is the number of trials, and p is the prob of success. So in your case the variance is:

625\cdot 0.29\cdot 0.71 \approx 129

(I am intentionally rounding to nearest integer to make the variance a meaningful value, since the events are discrete and not fractional measurements)

5(x+2)=6x+3x-14 please solve
zavuch27 [327]

Answer:

5(x+2)=6x+3x−14

Step 1: Simplify both sides of the equation.

5(x+2)=6x+3x−14

(5)(x)+(5)(2)=6x+3x+−14(Distribute)

5x+10=6x+3x+−14

5x+10=(6x+3x)+(−14)(Combine Like Terms)

5x+10=9x+−14

5x+10=9x−14

Step 2: Subtract 9x from both sides.

5x+10−9x=9x−14−9x

−4x+10=−14

Step 3: Subtract 10 from both sides.

−4x+10−10=−14−10

−4x=−24

Step 4: Divide both sides by -4.

−4x

−4

=

−24

−4

x=6

Answer:

x=6

Rewrite the following equation in standard form.<br> y = 10x + 2
Naddika [18.5K]

Answer:  -10x + 1y = 2

Step-by-step explanation:

The standard formula says that  Ax + By = C   where A is the coefficient of the x variable, B is the coefficient of the y variable, and C is the constant value.

   y = 10x + 2   Subtract 10x from both sides of the equation .

-10x     -10x

-10x + 1y = 2

PLZ HELP ASAP!!!!!!!! WILL MARK YOU BRAINLIEST THX!
anygoal [31]

Answer:

The first question is the third choice. Divide by two to get proper squaring. Anytime there is a number in front of the x in a situation like that, always divide by that number on both sides first. Then go from there.

The second question is also the third choice. The square root of 64 is 8. It can't be negative because square rooting is always positive unless you want a weird "i" in there. That's for algebra 2 and beyond so don't worry about it mate.

The lengths of the legs of a right triangle are 4 cm and 6 cm. If the triangle is rotated about one of its legs to create a righ
Assoli18 [71]
If you rotate about the leg of length 4 then the radius of the base of the cone is 6 and the height is 4.
Volume of a cone is V=1/3*pi*r^2*h
V=1/3*pi*6^2*4
=1/3*pi*36*4
=pi*48
=150.8 cm^3

To make sure that is the greatest volume we can figure the other cone.
If you rotate around the leg of length 6 your radius will be 4 and your height will be 6.
V=1/3*pi*4^2*6
V=100.5 cm^3
