dedylja [7]

Answer:

I’m pretty sure it’s B)- Z

Step-by-step explanation:

18. The correct table must display the following information.

38% prefer turkey with mayonnaise 20% prefer turkey with mustard 24% prefer ham with mayonnaise 18% prefer ham with mustard

In tables Z and W, each table totals 50 people.

To find the relative frequencies of the data in these tables, divide each number in the table by 50.

In tables X and Y, each table totals 100 people.

To find the relative frequencies of the data in these tables, divide each number in the table by 100.

The only table which is a possible representation of the data collected is table Z.

Whaaaaaaaaaaaaat????

Answer:

  7 pizzas

Step-by-step explanation:

For a difference in price of $58 -25 = $33, a customer gets a difference in number of 5 -2 = 3 pizzas. Then a pizza costs $33/3 = $11.

The cost of 2 pizzas is $22, so the delivery charge is $25 -22 = $3.

For $80, after subtracting the $3 delivery charge, $77 goes to the cost of pizzas. For that amount, $77/$11 = 7 pizzas will be delivered.

Between the time Iko woke up and lunchtime, tue temperature rose by 11 degrees. Then by the time he went to bed, the temperature
Ierofanga [76]

Answer:

T_b=(x-3)\textdegree

Step-by-step explanation:

let x° be temperature when he woke up. Given that the temperature rose  by 11° then later dropped by 14°. Also let T_b be temperature at time she went to bed.

-We add the temperature rise and subtract the temperature drop to find temperature at time she goes to bed.

-The temperature relative to time of waking up can be expressed as:

T_b=x\textdegree\pm\bigtriangleup T\textdegree\\\\T_b=x\textdegree+11\textdegree-14\textdegree\\\\T_b=(x-3)\textdegree

Hence, the temperature relative to the time Iko woke up is (x-3)°
