Can someone do this for me please?! Just the answer pls

A. What do you notice about each exterior angle measurement when you arrange the triangles so that the three angles form a strai

AysviL [449]

The sum of angles inside a triangle is the sum of angles 1, 2 and 3, which form a straight line, therefore 180 degrees.

The sum of the exterior angles
angle exterior angle
1 2+3
2 1+3
3 1+2
total 2+3+1+3+1+2=2(1+2+3)=2(180)=360 degrees.

Managers at an automobile manufacturing plant would like to estimate the mean completion time of an assembly line operation, . T

Vinil7 [7]

Answer:

The appropriate answer is "144".

Step-by-step explanation:

Given:

Population standard deviation,

$\sigma=10.4$

Margin of error,

$E=1.7$

$CL=95$ %

$CL=1-\alpha$

Or,

$\alpha=1-CL$

$=1-0.95$

$=0.05$

Now,

Critical value,

= $Z_{\frac{\alpha}{2} }$

= $Z_{\frac{0.05}{2} }$

= $1.96$

The minimum sample size will be:

⇒ $n=\frac{Z^2_{\frac{\alpha}{2} }(\sigma)^2}{E^2}$

By putting the values, we get

$=\frac{(1.96)^2(10.4)^2}{(1.7)^2}$

$=\frac{415.5074}{2.89}$

$=143.774$

or,

$=144$

Which is an exponential decay function? f start bracket x end bracket equals Three-fourths start bracket Seven-fourths end brack

Rainbow [258]

Answer:

The exponential decay function is $f(x)=\frac{3}{2}(\frac{8}{7})^{-x}$ ⇒ 3rd answer

Step-by-step explanation:

* Lets explain the exponential decay function

- The general form of an exponential Function is $f(x)=a(b)^{x}$ ,

where a is the initial value and b is growth factor

- If b > 1 , then the function is exponential growth function

- If 0 < b < 1 , then the function is exponential decay function

- The function $f(x) = a(b)^{-x}$ can be written as

$f(x)=a(\frac{1}{b})^{x}$

# <em>Remember</em>: if 0 < b < 1 , then 1/b > 1 , then change the negative

sign of the power by reciprocal the growth factor to decide the

function is growth or decay

* Lets solve the problem

1. $f(x)=\frac{3}{4}(\frac{7}{4})^{x}$

∵ b = 7/4

∵ 7/4 is greater than 1

∴ f(x) is an exponential growth function

2. $f(x)=\frac{2}{3}(\frac{4}{5})^{-x}$

- Change the (-x) to x by reciprocal (4/5) to (5/4)

∴ $f(x)=\frac{2}{3}(\frac{5}{4})^{x}$

∵ b = 5/4

∵ 5/4 is greater than 1

∴ f(x) is an exponential growth function

3. $f(x)=\frac{3}{2}(\frac{8}{7})^{-x}$

- Change the (-x) to x by reciprocal (8/7) to (7/8)

∴ $f(x)=\frac{3}{2}(\frac{7}{8})^{x}$

∵ b = 7/8

∵ 7/8 is greater than 0 and smaller than 1 ⇒ 0 < 7/8 < 1

∴ f(x) is an exponential decay function

* The exponential decay function is $f(x)=\frac{3}{2}(\frac{8}{7})^{-x}$
