The solution set -18 and 0 are the true values of the absolute value equation

The absolute value equation that has the a solution set of -18 and 0 is |x + 9| = 9

<h3>How to determine the absolute value equation?</h3>

From the figure, the solution sets of the absolute value equation are given as:

x = {-18, 0}

Calculate the mean of the solution set

Mean = 0.5 * (-18 + 0)

Mean = -9

Calculate the difference of the solution set divided by 2

Difference = (0 + 18)/2

Difference = 9

The absolute value equation is the represented as:

|x - Mean| = Difference

Substitute known values

|x + 9| = 9

Hence, the absolute value equation that has the a solution set of -18 and 0 is |x + 9| = 9

Stock worth $80 a share dropped in value by 15% on Tuesday, then increased by $7 the next Wednesday and, finally, increased by 1

USPshnik [31]

Answer:

The final price of share is $84

Step-by-step explanation:

Initial price of share = $ 80

The price of share is dropped by 15% on Tuesday

Drop in share = 15 % of 80 = 0.15×80 = $12

Price of share after 15% drop in price = $80 -$12 = $ 68

Price of share increased by $7 on Wednesday

Price of share on Wednesday = $68 +$7 =$ 75

on Thursday the price of share was increased by 12%

So the price of share on Thursday = price of share + 12 % of price of share

= $75 +12 % of $ 75

= $75 +0.12 ×$ 75

= $ 75 +$9 = $ 84

The final price of share is $84

What is the best estimated of the total number of students that attended clubs on Friday

s2008m [1.1K]

All you would have to do is round to the nearest 10th number (ex. From 26 to 30) for all the clubs including both boys and girls. Then you add them all together. Rounding makes estimating easier.

A keypad at the entrance of a building has 10 buttons labeled 0 through 9. What is the probability of a person correctly guessin

A keypad at the entrance of a building has 10 buttons labeled 0 through 9. What is the probability of a person correctly guessing a 9-digit entry code if they know that no digits repeat?

Answer:

the probability of a person correctly guessing a 9-digit entry code if they know that no digits repeat is 0.1

Step-by-step explanation:

We know that probability= number of required outcomes /number of all possible outcome.

From the given information;

the number of required outcome is guessing a 9-digit = 1 outcome

the number of all possible outcome = ¹⁰C₉ since there are 10 numbers and 9 number are to be selected.

Since there are only 9-digit that opens the lock;

the probability of a person correctly guessing a 9-digit entry code is

$P =\dfrac{1}{^{10}C_9}$

$P =\dfrac{1}{\dfrac{10!}{9!1!}}$

$P =\dfrac{1}{10}$

P = 0.1
