Answer:
The pizza heats up an average of 7.50 degrees per minute
Step-by-step explanation:
The table shown
Time (minutes) Temperature (degrees Celsius)
1 2.52
7 47.547
13 92.592
Since the pizza was heated at a constant rate, we can model the experiment as a line, where the slope represents how fast the pizza was heated
Slope
m = (y2 - y1)/(x2 - x1)
Let
(x1,y1) = (7, 47.547)
(x2,y2) = (13, 92.592)
m = (92.592 - 47.547)/(13-7)
m = 7.5075
The pizza heats up an average of 7.50 degrees per minute
Answer:
35
Step-by-step explanation:
You have to divide 280 by 8 and that's how you get it.
The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.
<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the cost of white chocolate chip and y represent the cost of oatmeal dough, hence:
12x + 6y = 192 (1)
Also:
6x + 12y = 222 (2)
From both equations:
x = 9, y = 14
The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.

Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H_0: p1 - p2=0
H_a: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575
