The cost in dollars, y, of a large pizza with x toppings from Pat’s Pizzeria can be modeled by a linear function. A large pizza with no toppings costs $14.00. A large pizza with 2 toppings costs $17.50. What is the cost of a pizza with 5 toppings? Round to the nearest penny.

Answer 1

Answer:

Answer:

The cost a pizza with 5 toppings is $22.75

Step-by-step explanation:

Consider the provided statement.

It is given that A large pizza with no toppings costs $14.00.

A large pizza with 2 toppings costs $17.50.

We can translate the problem and given into data points: (0, 14) and (2,17.50)

Where x coordinates represents the toppings and y is the cost.

Now the use the point-slope form: $y - y_1 = (y_2-y_1)/(x_2-x_1) (x-x_1)$

Substitute the respective values.

$y - 14 = (17.50-14)/(2-0) (x-0)$

$y - 14 = 1.75 (x)$

$y= 1.75x+14$

Hence, the required equation is $y= 1.75x+14$

Now find the cost of pizza with 5 toppings by substituting x=5 in above equation.

$y= 1.75(5)+14$

$y= 8.75+14$

$y= 22.75$

Hence, the cost a pizza with 5 toppings is $22.75

Answer 2

Answer: First find how much one topping is: subtract the L price from the L2T price: 17.50-14=3.50. Divide by 2: 3.50/2=1.75. Multiply by 5: 1.75•5=8.75. Add the topping cost to the L pizza cost: 8.75+14=22.75. $22.75 :)

Identify each quantity as a parameter or statistic Write "parameter" or "statistic" (without quotations). a) X: parameter b) S: statistic c) o: statistic هما d) u: parameter

Answers

The classification of each quantity as either a parameteror statistic is given thus :

X: parameter
S: statistic
o: statistic
u: parameter

a) X: parameter - A numerical summary of a population, and X represents a population parameter.

b) S: statistic - A numerical summary of a sample, and S represents a sample statistic.

c) o: statistic - Similarly, "o" represents a sample statistic, as it is used to denote the sample standard deviation.

d) u: parameter - "u" represents a population parameter, often used to denote the population mean.

Given that cos42° is simpler to 0.743, What is the sine of the complementary angle?

Answers

The cos of an angle and the sine of its complement are the same number.
Spend a couple of minutes looking at a right triangle, and reviewing the definitions of sin and cos, and you'll see why.

cos(42)=sin(90-42)

So in this case:

cos(42)=sin(48)

As:

A complementary angle is either of two angles whose sum is 90 degrees. {Source: Google}
