The U.S. Food and Drug Administration (FDA) performed a study that compared the carbohydrate content (as a percentage of weight)

of several major brands of corn and potato chips. Fourteen brands of corn chips were sampled and 14 brands of potato chips were sampled. Data was collected and the following 95% confidence interval was computed for the difference in means. Intrepret the 95% confidence interval for the difference in the mean carbohydrate content between the Corn Chip and Potato Chip groups. The C.I. is: (27.292,39.836)

Answer:

95% confidence interval for the difference in the mean carbohydrate content between the corn chip and potato chip group is between a lower limit of 27.292 and an upper limit of 39.836.

Step-by-step explanation:

Confidence interval is given by mean +/- margin of error and is expressed by enclosing the lower and upper limits of the mean separated by a comma in parentheses.

95% confidence interval for the difference in mean carbohydrate content between the corn chip and potato chip groups is given as (27.292, 39.836). This means that the difference in mean carbohydrate content between the two chip groups is between 27.292 and 39.836.

Cheddar Cheese

Complete question :

Cheddar Cheese

$3/lb

Swiss Cheese

$5/lb

Keisha is catering a luncheon. She has $30 to spend on a mixture of Cheddar cheese and Swiss cheese. How many pounds of cheese can Keisha get if she buys only Cheddar cheese? Only Swiss cheese? A mixture of both cheeses?

What linear equation in standard form can she use to model the situation?

Answer:

10 lbs of cheddar cheese

6 lbs of Swiss cheese

$3a + $5b = $30

Step-by-step explanation:

Given that :

Cheddar cheese = $3/lb

Swiss cheese = $5/lb

Total amount budgeted for cheese = $30

How many pounds of cheese can Keisha get if she buys only Cheddar cheese?

Pounds of cheedar cheese obtainable with $30

Total budget / cost per pound of cheddar cheese

$30 / 3 = 10 pounds of cheedar cheese

Only Swiss cheese?

Pounds of cheedar cheese obtainable with $30

Total budget / cost per pound of Swiss cheese

$30 / 5 = 6 pounds of Swiss cheese

A mixture of both cheeses?

What linear equation in standard form can she use to model the situation?

Let amount of cheddar cheese she can get = a

Let amount of Swiss cheese she can get = b

Hence,

(Cost per pound of cheddar cheese * number of pounds of cheddar) + (Cost per pound of Swiss cheese * number of pounds of Swiss cheese) = total budgeted amount

(3 * a) + (5 * b) = $30

$3a + $5b = $30

Se van a transportar sacos que contienen 50 kg de azúcar cada uno, el camión que se va utilizar para el transporte de los sacos
LekaFEV [45]

Function: 50x=8000 (maximum number of packages: 160)

Step-by-step explanation:

In this problem, we have:

C=8 ton = 8000 kg is the capacity of the truck (the amount of mass that can be stored in the truck)

p = 50 kg is the mass of each package that need to be stored in the truck

We can find the number of packages that can be transported as follows: calling this number x, the total mass of x packages is

p\cdot x

This amount should be at most equal to the capacity of the truck, therefore:

px=c

And substituting the numbers,

50x=8000

And solving the equation, we can found the number of packages that can fit into the truck:

x=\frac{8000}{50}=160

Use the net as an aid to compute the surface area of the triangular prism.
Harrizon [31]

Answer:

Option C. 564\ mm^{2}

Step-by-step explanation:

we know that

The surface area of the triangular prism using the net is equal to the area of two triangles plus the area of three rectangles

so

SA=2(\frac{1}{2})(10)(12)+2(13)(14)+(10)(14)

SA=60+364+140

SA=564\ mm^{2}
