The y-intercept of any straight non-vertical line refers to the y-value of the point where the line crosses the y-axis - that is

, where the x-coordinate is zero.
This can be (choose all that apply)



Group of answer choices

the change of the y-coordinates divided by the change in the x-coordinates

be always the location of the line in the xy coordinate system-that is, where the line hits the y-axis.

always be the location of the line in the xy coordinate system where the line hits the x-axis

the initial value of the output variable when the input variable is time. The y-intercept has an x-coordinate of zero, so if the input variable is time, the y-intercept is referred to as the starting value.

What is the 4th term in the sequence? <br><br> C(1)=56<br> C(n)= c(n-1)•1/2
Anton [14]

Answer:

The 4th term is 7

Step-by-step explanation:

we have

C(n)=C(n-1)\frac{1}{2}

C(1)=56

step 1

Find C(2)

For n=2

C(2)=C(1)\frac{1}{2}

C(2)=(56)\frac{1}{2}=28

step 2

Find C(3)

For n=3

C(3)=C(2)\frac{1}{2}

C(3)=(28)\frac{1}{2}=14

step 3

Find C(4)

For n=4

C(4)=C(3)\frac{1}{2}

C(4)=(14)\frac{1}{2}=7

therefore

The 4th term is 7

xP(x)00.2510.0520.1530.55Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal pl
Nookie1986 [14]

The Solution:

Given:

Required:

Find the standard deviation of the probability distribution.

Step 1:

Find the expected value of the probability distribution.

E(x)=\mu=\sum_{i\mathop{=}0}^3x_iP_(x_i)\begin{gathered} \mu=(0\times0.25)+(1\times0.05)+(2\times0.15)+(3\times0.55) \\  \\ \mu=0+0.05+0.30+1.65=2.0 \end{gathered}

Step 2:

Find the standard deviation.

Standard\text{ Deviation}=\sqrt{\sum_{i\mathop{=}0}^3(x_i-\mu)^2P_(x_i)}=(0-2)^2(0.25)+(1-2)^2(0.05)+(2-2)^2(0.15)+(3-2)^2(0.55)=4(0.25)+1(0.05)+0(0.15)+1(0.55)=1+0.05+0+0.55=1.60

Thus, the standard deviation is 1.60

Answer:

1.60

3. A cone has a heighth and a base with radius r. You want to change the cone so its volume is tripled. What is the new height i
Sphinxa [80]

Answer:

Hence the new height  is 3 times the original height .(h1=3h)

Step-by-step explanation:

Given:

A cone with  has height and base with radius r .

To Find:

What is new height

Solution:

Consider as cone with height h base radius r, and volume v

Here given that only height changes for the cone  i.e. r remains the unchanged or same or constant

The volume for a regular cone is given by ,

V=pie*r^2*h/3

Here V is directly proportional to h i.ee pie ,3 and r being constant

V=K*h

i.e V/h=constant

V1 and h1 are new dimensions for new cone

V/h=V1/h1

Here V1=3V

So V/h=3V/h1

1/h=3/h1

i.e  h1=3h

Hence the height  is 3 times the original height .

$12,800 15% is taken out what's the answer
Anuta_ua [19.1K]

Answer:

$10,880

Step-by-step explanation:

15% = 15 ÷ 100 = 0.15

So 15% of 12800 = 0.15 x 12800 = 1920

Therefore, 12800 - 1920 = 10880

OR

12800 x (1 - 0.15) = 10880
