Answer:

1 question. How many people are there in your family?

Step-by-step explanation:

let no. of people be x.

restaurant one will be cheaper if:

75 + 12.50x < 14x

75 < 1.50x

x > 50

restaurant two will be cheaper if:

x < 50

If you have 50 people in your family, it's the same for both so just choose anything you'd like

Answer:

The margin of error is $ME = 2.2962$

Step-by-step explanation:

From the question we are told that

The number of student is $n = 500$

The highest amount is $A =$ $200

The lowest amount is $B =$ $75

The sample mean is $x =$ &140

The Standard deviation of this set is mathematically evaluated as

$s = \frac{A-B}{4}$

Substituting values

$s = \frac{200-75}{4}$

$s = 31.25$

The margin of error (ME) is mathematically evaluated as

$ME = t_{n-1}__{\alpha }} * \frac{s}{\sqrt{n} }$

Where $t_{n-1}__{\alpha }}$ is the critical value for $\alpha = 0.05$ i.e the significance level

From the critical value table this is $t_{n-1}__{\alpha }} = 1.649$

So

$ME = 1.649 * \frac{31.25}{\sqrt{500} }$

$ME = 2.2962$

Find the first partial derivatives of the function f(x,y,z)=4xsin(y−z)

Amanda [17]

Answer:

$f_x(x,y,z)=4\sin (y-z)$

$f_x(x,y,z)=4x\cos (y-z)$

$f_z(x,y,z)=-4x\cos (y-z)$

Step-by-step explanation:

The given function is

$f(x,y,z)=4x\sin (y-z)$

We need to find first partial derivatives of the function.

Differentiate partially w.r.t. x and y, z are constants.

$f_x(x,y,z)=4(1)\sin (y-z)$

$f_x(x,y,z)=4\sin (y-z)$

Differentiate partially w.r.t. y and x, z are constants.

$f_y(x,y,z)=4x\cos (y-z)\dfrac{\partial}{\partial y}(y-z)$

$f_y(x,y,z)=4x\cos (y-z)$

Differentiate partially w.r.t. z and x, y are constants.

$f_z(x,y,z)=4x\cos (y-z)\dfrac{\partial}{\partial z}(y-z)$

$f_z(x,y,z)=4x\cos (y-z)(-1)$

$f_z(x,y,z)=-4x\cos (y-z)$

Therefore, the first partial derivatives of the function are $f_x(x,y,z)=4\sin (y-z), f_x(x,y,z)=4x\cos (y-z)\text{ and }f_z(x,y,z)=-4x\cos (y-z)$ .

Given: P is a point on the perpendicular bisector, I of MN.<br> Prove: PM = PN

Hatshy [7]

Answer:

Step-by-step explanation:

I can't make specific statements about the proof because the midpoint is missing.

Givens

There are two right angles created by where the perpendicular bisector meats MN. Both are 90 degrees.

MN is bisected by the point on MN where the perpendicular meets MN

The Perpendicular Bisector is is common to both triangles.

Therefore the two triangles are congruent by SAS

PM = PN Parts contained in Congruent triangles are congruent.
