Its the distributive property


anyanavicka [17]4 years ago

We have been given the equation

-3(x+2)=9

The first steps is given as -3x-6=9

In this step, Tyra has distributed the term -3 over the parenthesis, as shown below

-3(x+2)=9\\-3\cdot x+ (-3)(2)=9\\-3x-6=9

We know the distributive property is given by

a(b+c)=ab+ac

Therefore, we can say that Tyra has used distributive property in the first step.

C is the correct option.

HD, JD, and KD are the perpendicular bisectors of triangle EFG. Find each length
erik [133]
Since all three are perpendicular bisectors, the segment it bisects is equal on both sides.

Let's do segment EF.
HD bisects EF, therefore EF is split in half. All you have to do is add 16 to itself. This will be the same for the remaining two sides of that triangle. I'm hoping that was the only lengths you needed.

Find the volume of the sphere. Round your answer to the nearest tenth.
Viktor [21]

Answer:

Volume of sphere = 44.57 cm³

Step-by-step explanation:

Given:

Diameter of sphere = 4.4 centimeter

Value of π = 3.14

Find:

Volume of sphere

Computation:

Radius of sphere = Diameter of sphere / 2

Radius of sphere = 4.4 / 2

Radius of sphere = 2.2 centimeter

Volume of sphere = [4/3][π][r³]

Volume of sphere = [4/3][3.14][2.2³]

Volume of sphere = [4/3][3.14][10.648]

Volume of sphere = [1.333][3.14][10.648]

Volume of sphere = 44.568

Volume of sphere = 44.57 cm³

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 11.7 years, and standard deviation of
lesya692 [45]

Answer: 9.2 years

Step-by-step explanation:

Given the following :

Mean(m) = 11.7 years

Standard deviation (s) = 1.2 years

Recall the z-score formula :

Z = (x - m) / s

We can find the z-score by locating the value of 2% in the negative z-table, then solve for x.

2% = 0.02

0.02 falls most closely to 0.02018whuch is under - 2.05.

Using the z-score value in the formula above :

-2.05 = (x - 11.7) / 1.2

Cross multiply

(-2.05 × 1.2) = x - 11.7

-2.46 = x - 11.7

x = - 2.46 + 11.7

x = 9.24 years
