The probability of drawing a red marble and then a green marble is:

P = 1/6.

<h3>How to find the probability?</h3>

In the jar we have a total of 16 marbles, such that:

  • 10 are green.
  • 2 are blue
  • 4 are red.

First, the probability of getting a red marble is give by the quotient between the number of red marbles and the total number of marbles:

p = 4/16 = 1/4

Now we need to draw a green one, the probability is computed in the same way, but this time there are 15 marbles, because we already took one.

q = 10/15

The joint probability (first drawing red, then green) is given by the product between the individual probabilities:

P = p*q = (1/4)*(10/15) = 10/60 = 1/6

A 6 inch personal pizza has 650 calories, with 240 of those from fat. A 14 inch pizza is cut into 8 slices. Estimate the number
professor190 [17]

<u>Answer:</u>

<em>Number of calories in one slice of a 14 inch pizza is 189.825. </em>

<u>Step-by-step explanation:</u>

Given that 6 inch pizza has <em>650 calories. </em>

Therefore 1 inch pizza has \frac{650}{6} <em>calories. </em>

14 inch pizza will have  

\frac{650}{6} \times 14=216.67 \times 14=1516.66 \ calories

Given that the 14 inch pizza is divided into 8 slices.

Therefore each slice of the 14 inch pizza will have

<em>\frac {1516.66}{8} =189.825 calories</em>

This table shows the input and output values for an exponential function f(x) .
Gre4nikov [31]
The correct answer is:  [B]:  "4 " .
______________________________________
Explanation: 
______________________________________
Refer to the table (provided within the actual question).

Note that the "inputs" ; or "x-values" ; are all listed in "chronological order" ; and are all "one (1) unit apart. and range from:  "x = -3"  to "x = 3" .

When "x = 0" ; the "output" ; or "f(x)"  is "1/4" . 
When "x = 1"  ; the "output" ; or "f(x)" is:  "1" .
_________________________________________________
So; the ratio of these two "outputs"  is:  "¼ : 1"  ; or, write as:
  " (¼) / 1 " ;   and note that:  " (¼) / 1 =  (¼) ÷ 1 = ¼.

However; note that: "1/4" ; or  "1:4" is NOT among the [answer choices given].

However, the ratio of the 2 (two) corresponding "outputs"; chronologically,
going from when "x = 1" ; to "x = 0" ;  is:  "1 : ¼" ; or;  write as:  "1 / (¼)" ; 

And note that:  "1 / (¼)"  =  " 1 ÷ (¼) " = 1 * (4/1) = 1 * 4 = "4" .

This corresponds to:  Answer choice: [B]:  "4<span>" .
</span>_________________________________________________
Let us further confirm that this answer is correct:
_________________________________________________
When x = 3;  the "output" is:  "16" .

When x = 2;  the "output" is:  "4" .

The ratio:  "16/4 = ?  4 ? " ;    →  Yes!
_________________________________________________
When x = 2;  the "output" is:  "4" .

When x = 1;   the "output" is:  "1" .

The ratio:  "4/1  = ?  4 ? " ;    →  Yes!
_________________________________________________
When x = 1;  the "output" is:  "1" .

When x = 0; the "output" is:  "(¼)" .

The ratio:  "1 / (¼)  = ?  4 ? " ;  

   →  "1 / (¼)"  =  " 1 ÷ (¼) " = 1 * (4/1) = 1 * 4 = "4" . YES!
________________________________________________
When  x = 0; the "output" is:  "(¼)" .

When  x = -1; the "output" is:  "(¹/₁₆)" .

The ratio:  "(¼) / (¹/₁₆)  = ?  4 " ? ;  
  
   →  "(¼) / (¹/₁₆) = "(¼) ÷ (¹/₁₆) " =  "(¼) * (¹⁶/₁) = (1*16) / (4*1) = 16/4 = "4" .  Yes!
________________________________________________________
When  x = -1; the "output" is:  "(¹/₁₆)" .

When  x = -2; the "output" is:  "(¹/₆₄)" .

The ratio:  "(¹/₁₆) / (¹/₆₄)  = ?  4 " ? ;  
  
   →  "(¹/₁₆) / (¹/₆₄)  = "(¹/₁₆) ÷ (¹/₆₄)" = "(¹/₁₆) * (⁶⁴/₁)" = (1*64) / (16*1) = 64/16 = "4" . Yes!
__________________________________________________________
When  x = -2; the "output" is:  "(¹/₆₄)" .

When  x = -3; the "output" is:  "(¹/₂₅₆)" ,

The ratio:  "(¹/₆₄)/(¹/₂₅₆)  = ?  4 " ? ;  
  
 → "(¹/₆₄) / (¹/₂₅₆)"  ;
 
       =   " (¹/₆₄) ÷ (¹/₂₅₆)" = " (¹/₆₄) * (²⁵⁶/₁) " = (1*256) / (64*1) = 256/164  =  "4 " . Yes!
__________________________________________________________
  → So; as calculated; the ratio is:  "4" ;  which is:
__________________________________________________________
  →  Answer choice:  [B]:  "4" .

The budget for carter museum's annual party is $10,000.food accounts for 1/2of the budget, beverages for 1/4,and decorations for
Elodia [21]
Hello! So $10,000 is the annual budget. 50% of the budget is spent on food, 25% of it is spent on beverages, 10% is spent on decorations, and the remaining 15% is spent on staff for the party. That's because 50 + 25 + 10 is 85. 100 - 85 is 15. Let's multiply the budget by 15% to find the amount spent on staff. 10,000 * 15% (0.15) is 1,500. There. $1,500 were spent on staff for the party.
