ira [324]
Question: Please help lily team won 8 out of 12 games.At that rate,how many games will her team win if it plays 21 games?The ratio is now: 8 : 12 = X : 21, where x is the unknown value of win they have and 21 is the total number of games they played=> 8 : 12 = x : 21=> 8 * 21 =   168 / 12 = 14Thus, the new ratio is 8 : 12 and 14 : 21they will be winning 14 games out of 21 plays<span>

x \geq -9; x \leq 6 or in interval notation [-9,6]

To find out what are the steps in solving the below inequality:

Given equation is 2x - 3 > 15

The absolute value function takes any term and transforms it to its non-negative form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent.

−15≤2x-3≤15

First, subtract 3  from each segment of the system of equations to isolate the x term while keeping the system balanced:

−15−3≤2x-3−3≤15−3

−18≤2x-6≤12

−18≤2x-6≤12

Now, divide each segment of the system by 2 to solve for x while keeping the system balanced:

-\frac{18}{2}\leq \frac{2x}{2} \leq \frac{12}{2}

-9 \leq x \leq 6

or

x \geq -9; x \leq 6

or in interval notation [-9,6]

on the horizontal axis.

The lines will be a solid line because the inequality operators contain "or equal to" clauses.

We will shade between the lines to show the interval:

Hence the steps to solve an inequality has been show

Put a lid on it! The supplier is considering two changes to reduce to 1% the
bija089 [108]

Answer:

A) 3.996 inches

B) 0.01

C) option B

Step-by-step explanation:

Note: The diameter of the lid is between : 3.95 and  4.05

A) calculate the supplier set mean diameter

std = 0.02 inch

P( x < 3.95 ) = 1% = 0.01

= P ( Z < (\frac{3.95 - u }{0.02}) ) = P ( Z < -2.3263 ) = 0.01

therefore :

(\frac{3.95 - u }{0.02})  = -2.3263

hence :<em> u </em>= 3.996 inches ( mean diameter )

B) At mean diameter = 3.98 calculate the value of std

P ( X < 3.95 ) = 0.01

= P ( Z < ( \frac{3.95-3.98 }{std } ) )  = P ( Z < -2.3263 ) = 0.01

therefore

( \frac{3.95-3.98 }{std } ) = -2.3263

hence std = 0.01 inch

C) option B is preferable because its mean diameter is smaller and  the percent of lids too large to fit is considered more carefully using option B
