Answer:
Step-by-step explanation:
no
as
P(A∩B)=P(A)×P(B)
and P(A)>1/2
also
P(A)≤1
similarly P(B)>1/2
and
P(B)≤1
P(A)×P(B)≤1
so P(A and B) not greater than 1

A 4 1/2 ounce hamburger patty has 25 1/2 grams of protein. Determine the grams of protein per ounce each type of food.
Select from the drop down menus to correctly complete each statement
Answer:
Option c. 5.7 grams
Option b. 5.3 grams
Step-by-step explanation:
(a) A [tex]4\frac{1}{2}[/tex] ounce hamburger patty has [tex]25\frac{1}{2}[/tex] grams of protein.
first we convert mixed fraction to improper fraction.
Amount of protein a [tex]\frac{9}{2}[/tex] ounce hamburger patty has = [tex]\frac{51}{2}[/tex] grams
∴ Amount of protein a 1 ounce hamburger patty has = [tex]\frac{\frac{51}{2} }{\frac{9}{2} }[/tex]
= [tex]\frac{51}{2} \times \frac{2}{9}[/tex]
= [tex]\frac{51}{9}[/tex]
= [tex]\frac{17}{3}[/tex] = [tex]5\frac{2}{3}[/tex] = 5.7 grams
(b) A 6 ounces of fish has 32 grams of protein.
∴ The amount of protein a 1 ounce of fish has = [tex]\frac{32}{6}[/tex]
= 5.3 grams
A hamburger patty has approximately 5.7 grams of protein per ounce.
A fish has approximately 5.3 grams of protein per ounce.
Which is a correct expansion of (2x+3)(2x^{2} -5)?
Answer:
4x^{3} + 6x^{2} -10x -15
Step-by-step explanation:
(2x+3)(2x^{2} -5)
2x × 2x^{2} + 2x× (-5) + 3× 2x^{2} + 3 ×(-5)
=4x^{3} -10x + 6x^{2} -15
= 4x^{3} + 6x^{2} -10x -15

SHARE THE TREASURE 3
Captain Salamander and his crew have found 24 bars of gold.
The captain decides that he is going to share all the treasure out.
He puts 1/3 of the bars to aside for himself.
He gives 1/4
of the bars to his friend Bill
He shares out 7 bars with the rest of his crew.
How many bars does he have left?
Z
/ 17
.
Answer:
3 bars
Step-by-step explanation:
Total no. of gold bars = 24.
Fraction of bar captain allocated to himself = 1/3 of the bars
no. of bars he allocated to himself = 1/3 of 24 = 1/3 * 24 = 8
Fraction of bar captain allocated to his friend bill = 1/4 of the bars
no. of bars he allocated to his friend bill = 1/4 of 24 = 1/4 * 24 = 6
No . of bars captain allocated to rest of crew = 7
Total no of bars which are allocated altogether =
no. of bars he allocated to himself +no. of bars he allocated to his friend bill +No . of bars captain allocated to rest of crew
substituting the value of above summation variable as calculated above we have
Total no of bars which are allocated altogether = 8+6+7 = 21
No. of bars left = total no. of bars - Total no of bars which are allocated altogether = 24 - 21 = 3
Thus 3 gold bars are left.
Solve plzzzz As attached
Answer:
Step-by-step explanation:
Basically, we're solving for a.
w = 3(2a + b) - 4
w = 6a + 3b - 4
-6a + w = 3b - 4
-6a = -w + 3b - 4
a = (w - 3b + 4)/6

Solve the equation by completing the square. x2 + 20x + 82 = 7
Answer:
{-15, -5}
Step-by-step explanation:
The constant on the left needs to be the square of half the x-coefficient:
(20/2)^2 = 100
To get it to that value, we can add 18 to both sides of the equation:
x^2 +20x +100 = 25 . . . add 18 to both sides of the equation
(x +10)^2 = 25 . . . . . . . . write the left side as a square
x +10 = ±√25 = ±5 . . . . . take the square root
x = -10 ±5 = {-15, -5}
The solutions are x = -15 and x = -5.

The solution to 2x2 – 11 = 87 is .
Step-by-step explanation:
Step 1: Subtract 87 from both sides
[tex]2x^2 - 11 - 87 = 87 - 87[/tex]
[tex]2x^2 - 11 - 87 = 0[/tex]
Step 2: Factor
[tex]2x^2 - 11 - 87 = 0[/tex]
[tex]2(x + 7)(x - 7) = 0[/tex]
[tex]x + 7 = 0[/tex] and [tex]x - 7 = 0[/tex]
[tex]x = -7[/tex] and [tex]x = 7[/tex]
Answer: [tex]x = -7, 7[/tex]

Solve: -(1/4)m + 5 = 16
Answer:
m=-44
Explanation: distribute the negative and add -1/4 to m and then take the 5 away from 16 and then multiply both sides
Answer:
M = - 44
Step-by-step explanation:
You will start by subtracting 5 on both sides of the equation.
- (1/4)m + 5 =16
-5 -5
Simplify
- 1/4 m =11
Multiple both sides by - 4
(-1/4m)(-4)= 11 (- 4)
The final result is m equals negitive 4.
M = -44
HELPPPPP What is the combine legth of all the buttons longer than 1 inch
What’s the correct answer for this?
Answer:
(x + 5)² + (y - 7)² = 13
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 5, 7) and r = [tex]\sqrt{13}[/tex] , thus
(x - (- 5))² + (y - 7)² = ([tex]\sqrt{13}[/tex] )² , that is
(x + 5)² + (y - 7)² = 13 ← equation of circle

in a basketball game . Tina made 9 baskets . each dasket was worth either 2 or 3 points how many different numbers could represent the total points that Tina could have made?? answer me
Answer:
Tina could make are 10 Possible total points.
They number of possible total points are; 18, 19, 20, 21, 22, 23, 24, 25, 26 and 27.
Step-by-step explanation:
This is a zero-sum sort of deal. If tina makes 9 baskets, they can be all 2 points or all 3 points.
Let's make some number of 2 points "n". Then, the number of 3 points has to be 9 - n. The logic is exactly the same if we considered the number of 3 points made to be "n".
Thus, the maximum of this relationship is when n = 0.
Hence, 9 baskets gives the following possible permutations:
1) 0 number of 2 points and 9 number of 3 points = 27 points
2) 1 number of 2 points and 8 number of 3 points = 26 points
3) 2 number of 2 points and 7 number of 3 points = 25 points
4) 3 number of 2 points and 6 number of 3 points = 24 points
5) 4 number of 2 points and 5 number of 3 points = 23 points
6) 5 number of 2 points and 4 number of 3 points = 22 points
7) 6 number of 2 points and 3 number of 3 points = 21 points
8) 7 number of 2 points and 2 number of 3 points = 20 points
9) 8 number of 2 points and 1 number of 3 points = 19 points
10) 9 number of 2 points and 0 number of 3 points = 18 points
So the number of possible points Tina could make are; 18, 19, 20, 21, 22, 23, 24, 25, 26 and 27.
Wesson Company sold 10,000 units of its only product in the first half of the year. If sales increase by 12% in the second half of the year, which cost will increase?
