: Use The TI Calculator To Answer The Question. Find The Probability That A Z-score Will Be Between 0.7 And 1.4. A) 0.242 O B) 0

ZanzabumX [31]

Answer:

$P(0.7$

And we can find this probability with the following difference:

$P(0.7$

We can use the following commands on the ti 84

2nd>VARS>DISTR

And then we look for normalcdf and we input this:

normalcdf(0.7,1.4,0,1)

The other possible code would be:

normalcdf(-1000,1,4,0,1)-normalcdf(-1000,0.7,0,1)

And we got:

$P(0.7$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

For this case we want to find this probability:

$P(0.7$

And we can find this probability with the following difference:

$P(0.7$

We can use the following commands on the ti 84

2nd>VARS>DISTR

And then we look for normalcdf and we input this:

normalcdf(0.7,1.4,0,1)

The other possible code would be:

normalcdf(-1000,1,4,0,1)-normalcdf(-1000,0.7,0,1)

And we got:

$P(0.7$

using the equation representing the height of the firework (h = -16t^2 + v↓0 + h↓0), algebraically determine the extreme value o

Hitman42 [59]

Answer:

y = (-1/15)(x - 3)2 + 15

Step-by-step explanation:

The general equation of a parabola is

y = a(x - h)2 + k

If the halfway line if the origin, i.e. (x, y) = (0, 0), then the ball is kicked at (-12, 0) and it lands at (18, 0). By symmetry, the ball reaches its greatest height halfway between the starting and ending x values, or at x = 3. So, we know three points on this parabola: (-12, 0), (18, 0) and (3, 15).

Let us plug the first point into the generalized equation:

y = (x - h)2 + k

0 = (-12 - h)2 + k

So, k = -(-h - 12)2

or

k = -(h + 12)2, since we can factor out -1 and it becomes squared.

We can also plug (18, 0) into the generalized equation, and get:

0 = (18 - h)2 + k

So, k = -(18 - h)2

Since we have two expressions both equal to k, we can set them equal to each other and eliminate k:

-(h + 12)2 = -(18 - h)2

We can cancel out the negative signs and square out the terms on each side of the last equation.

h2 + 24h + 144 = h2 - 36h + 324

We can cancel out h2 and then solve for h.

24h + 144 = -36h + 324

60h = 180

h = 3

Therefore, the generalized equation becomes

y = a(x - 3)2 + k

We know that if x = 3, y = 15 from out third point.

15 = a(3 - 3)2 + k

So, k = 15

Thus, the equation becomes

y = a(x - 3)2 + 15

We can then pick one of the other points, plug in the corresponding x and y and then solve for a. I choose (18, 0).

0 = a(18 - 3)2 + 15

0 = 152a + 15

Divide this equation through by 15.

0 = 15a + 1

or

a = -1/15

Therefore, the generalized equation is

y = (-1/15)(x - 3)2 + 15
