A chocolate company produces 2 types of chocolate type A and type B. The company selects 25 random packages of each type to chec

k their weight and finds that one package of type Ahas an incorrect weight and 3 packages of type B have an incorrect weight. How many packages should the company predict have an incorrect weight when it checks 2000 of each type?​

Answer:

80 chocolates type 'a' and 240 chocolates type 'b"

Step-by-step explanation:

if the company selects 2000 random chocolates of each type we ca predict that the amount of chocolates that have an incorrect weight will be:

Type 'a': 2000x0.04 = 80

Type 'b': 2000x0.12 = 240

The company is expected to find 80 chocolates type 'a' and 240 chocolates type 'b' that have incorrect weight.

1. Find the surface area for the given prism. (11<br> 8 in.<br> 10 in.<br> 14 in,
DedPeter [7]

Answer:

SA = 664 square inches

Step-by-step explanation:

Surface area is the area of all the sides added together.  A prism has six sides.

Take the dimensions and change them so each of the numbers are multiplied with the others.

14 * 10 * 8

14 * 10 = 140

14 * 8 = 112

10 * 8 = 80

Multiply each answer by 2 because there are two sides that have the same dimensions.

14 * 10 = 140 * 2 = 280

14 * 8 = 112 * 2 = 224

10 * 8 = 80 * 2 = 160

Add the areas together.

280 + 224 + 160 = 664  

SA = 664 square inches

Which matrix represents the system of equations shown below? 3x-5y=12 4x-2y=15
tatuchka [14]

Answer:

\left[\begin{array}{ccc}3&-5  &|12\\4&-2  &|15\\\end{array}\right]

Step-by-step explanation:

When making a matrix of two equations with the variables x and y, the result will be a matrix with three columns:

  • a column for the values of x in each equation
  • a column for the values of y in each equation
  • a column for the independent values of each equation

since our system of equations is:

3x-5y=12\\ 4x-2y=15

we can see that the value for x in the first equation is 3 and in the second equation is 4, thus the first column will have the numbers 3 and 4:

\left[\begin{array}{ccc}3&&\\4&&\\\end{array}\right]

Now for the values of y we hvae -5 in the first equation and -2 in the second equation, we update the matrix with another column with the values of -5 and -2:

\left[\begin{array}{ccc}3&-5&\\4&-2&\\\end{array}\right]

Finally, the last column is the independent values of each equation (or the results) in the first equation that number is 12 and in the second equation is 15, thus the matrix is:

\left[\begin{array}{ccc}3&-5&12\\4&-2&15\\\end{array}\right]

usually there is a line separating the columns for the values of x and y, and the independent values:

\left[\begin{array}{ccc}3&-5  &|12\\4&-2  &|15\\\end{array}\right]

this is the matrix of the system of equations

Hallar la ecuación de la recta que pasa por los puntos A(1,3) y B(3,7). Representarla gráficamente. Indicar su pendiente.
Fynjy0 [20]

Answer:

<h2>A</h2>

Step-by-step explanation:

la recta:

y-yo=m(x-xo) (*)

P=(xo,yo)

m=\frac{Ya-Yb}{Xa-Xb}

substituindo:

m=\frac{3-7}{1-3}\\\\m=2

Seja P=A=(xo=1,yo=3), utilizando a formula (*)

y-3=2(x-1)\\y=2x-2+3\\y=2x+1
