Answer: 9 Apples

Step-by-step explanation:

Given the following :

Total number of bags = 12

Mean of the distribution(m) = 8

Number of apples (x):

6 - - - - 7 - - - - 8 - - - - 9 - - - - 10

Frequency (f) :

1 - - - - 4 - - - - 2 - - - - 3 - - - - 1

Therefore :

Let number of apples in the 12th bag = y

Frequency of 12th bag : (12 - 11) = 1

Mean of distribution(m) :

Sum of ( f * x) / sum of f

Sum of (f * x) = (6*1)+(7*4)+(8*2)+(9*3)+(10*1)+(y*1)

Sum of (f * x) = (6+28+16+27+10+y) = 87 + y

Sum of f = 12

From :

m = Sum of ( f * x) / sum of f

8 = (87 + y) / 12

87 + y = 12 * 8

87 + y = 96

y = 96 - 87

y = 9

Number of apples in 12th bag is 9 apples

Use a net to find the surface area of the right triangular prism shown:

erma4kov [3.2K]

Answer:

256 ft²

Step-by-step explanation:

Net comprises: 2 equal triangles, 2 equal rectangles and 1 smaller rectangle

Area of a triangle = 1/2 x base x height

⇒ area of one triangle = 1/2 x 10 x 7 = 35 ft²

Area of a rectangle = width x length

⇒ area of larger rectangle = 6 x 12 = 72 ft²

⇒ area of smaller rectangle area = 6 x 7 = 42 ft²

⇒ Total area = (2 x 35) + (2 x 72) + 42 = 256 ft²

You need 550 mL of a 50% alcohol solution. On hand, you have a 55% alcohol mixture. How much of the 55% alcohol mixture and pure

vitfil [10]

We need 500 ml of alcohol mixture and 50 ml of water.

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

The 50% concentration of the final solution is a result of mixing the 55% concentration with water, which is 0% concentration. Multiply the concentration of each liquid times the # of ml you will use, add these and divide by the total ml to get 50%

x = the number of ml of the 55% alcohol mixture

y = the number of ml of water

x + y = 550

$\frac{{0.55 x + (0) y }}{550} =0.50$

Again, the 0 above represents the water which is 0% concentration

$\frac{0.55 x}{550}$ = 0.50

0.55 x = 275

x = $\frac{275}{0.55}$ = 500

plug 500 into the equation x + y = 550

500 + y = 550

y = 50

Use 500 ml of the 55% solution and 50 ml of water.
