Zero is a solution for which inequality?
Helen [10]

Step-by-step explanation:

0 is right in the middle of all negative and all positive numbers.

0 is therefore larger than any negative number and smaller than any positive number.

and 0×n = 0, always, no matter what n is.

-0 = +0 = 0.

so, of course, only

4.1m > -16.4

is correct.

0 is not greater than 16.4.

0 is not smaller than -16.4.

What is the inverse of the function f(x) = 2x – 10?
noname [10]

Answer:

The inverse f-1(x) = ( x + 10)/2.

Step-by-step explanation:

f(x) = 2x - 10

Find x in terms of f(x):

2x = f(x) + 10

x = (f(x) + 10))/ 2

Replace x by the inverse f-1(x) and f(x) by x:

f-1(x) = (x + 10)/2.

The weights of certain machine components are normally distributed with a mean of 5.19 ounces and a standard deviation of 0.05 o
Brums [2.3K]

Answer:

The  weight that separate the top 8% by 5.2605 and the weight that separate bottom 8% by 5.1195.

Step-by-step explanation:

We are given that

Mean,\mu=5.19

Standard deviation,\sigma=0.05

We have to find the two weights that separate the top 8% and the bottom 8%.

Let x1 and x2 the two weights that separate the top 8% and the bottom 8%.

Z-value for p-value =0.08 =-1.41

For 8% bottom

Z=\frac{x_1-\mu}{\sigma}=-1.41

\frac{x_1-5.19}{0.05}=-1.41

x_1-5.19=-1.41\times 0.05

x_1=-1.41\times 0.05+5.19

x_1=5.1195

For 8% top

p-Value=1-0.08=0.92

Z- value=1.41

Now,

\frac{x_2-5.19}{0.05}=1.41

x_2-5.19=1.41\times 0.05

x_2=1.41\times 0.05+5.19

x_2=5.2605

(x1,x2)=(5.1195,5.2605)
