Step-by-step explanation: To write a percent as a fraction in lowest terms, remember that a percent is a ratio that compares a number to 100. In this example, 88% can be written as the ratio 88 to 100 or 88/100. Notice however that 88/100 is not in lowest terms so we need to divide both the numerator and denominator by 4 to get 22/25.

Therefore, 88% can be written as the fraction 22/25.

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. We can think of 88% as the ratio 88 to 100 or 88 divided by 100. Remember that dividing by 100 moves the decimal point two places to the left so 88 divided by 100 would move the decimal point two places to the left which would give us .88 or 0.88.

Therefore, 88% can be written as the decimal 0.82.

Each of the 25 balls in a certain box is either red, blue, or white and has a number from 1 to 10 painted on it. If one ball is

dem82 [27]

Answer:

Probability ball: white - P(W)P(W);

Probability ball: even - P(E)P(E);

Probability ball: white and even - P(W&E).

Probability ball picked being white or even: P(WorE)=P(W)+P(E)-P(W&E).

(1) The probability that the ball will both be white and have an even number painted on it is 0 --> P(W&E)=0 (no white ball with even number) --> P(WorE)=P(W)+P(E)−0P(WorE)=P(W)+P(E)−0. Not sufficient

(2) The probability that the ball will be white minus the probability that the ball will have an even number painted on it is 0.2 --> P(W)−P(E)=0.2P(W)−P(E)=0.2, multiple values are possible for P(W)P(W) and P(E)P(E) (0.6 and 0.4 OR 0.4 and 0.2). Can not determine P(WorE)P(WorE).

(1)+(2) P(W&E)=0 and P(W)−P(E)=0.2P(W)−P(E)=0.2 --> P(WorE)=2P(E)+0.2P(WorE)=2P(E)+0.2 --> multiple answers are possible, for instance: if P(E)=0.4P(E)=0.4 (10 even balls) then P(WorE)=1P(WorE)=1 BUT if P(E)=0.2P(E)=0.2 (5 even balls) then P(WorE)=0.6P(WorE)=0.6. Not sufficient.

Elenna [48]

Answer:
_______________________________________________________
The rewritten equation is:

" - 3x² + 30 + 225 = 0 " ;

which is ultimately simplified to:

" x² − 10 − 75 = 0 " .
___________________________________________________
The number of days is: "15 days" .
___________________________________________________

Explanation:
______________________________________________
Given:

h(x) = - 3x² + 30 + 225 ;

Rewrite as: " - 3x² + 30 + 225 = 0 " ;
__________________________________________________________
Multiply EACH SIDE of the equation by "-1" ; to get rid of the "-3" ;

-1 * {- 3x² + 30 + 225 = 0} ;

to get: " 3x² − 30 − 225 = 0" ;

Divide EACH SIDE of the equation by "3" ; to simplify; since:

"3", "30", and "225" are divisible by "3" ;

{3x² − 30 − 225} / 3 = 0 / 3 ;

to get:
______________________________________
" x² − 10 − 75 = 0 " ;

______________________________________
Let us factor:

-15 + 5 = -10 ;

-15 * 5 = -75 ;
_______________________________________
Rewrite as:

(x − 15) (x + 5) = 0 ;

x = 15; and x = -5 ;
_______________________________________
The number of days cannot be "negative value"; so we stick with:

"x = 15 days"

Y=-x - 3 What so the value of x

Sergeu [11.5K]

Answer:

x=−y−3

Step-by-step explanation:

Step 1: Flip the equation.

−x−3=y

Step 2: Add 3 to both sides.

−x−3+3=y+3

−x=y+3

Step 3: Divide both sides by -1.

$\frac{-x}{-1}$ = $\frac{y+3}{-1}$

x=−y−3
