Answer:
the statement that is not supported by the trend in the scatter plot is d) each additional pound adds about one hour of cooking time.
Answer:
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
Step-by-step explanation:
Given;
Confidence interval CI = (a,b) = (0.036, 0.086)
Lower bound a = 0.036
Upper bound b = 0.086
To express in the form;
p-e< p < p+e
Where;
p = mean Proportion
and
e = margin of error
The mean p =( lower bound + higher bound)/2
p = (a+b)/2
Substituting the values;
p = (0.036+0.086)/2
Mean Proportion p = 0.061
The margin of error e = (b-a)/2
Substituting the given values;
e = (0.086-0.036)/2
e = 0.025
Re-writing in the stated form, with p = 0.061 and e = 0.025
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
Answer:
slope is about 1.67
Step-by-step explanation:
2/1.2 ≈ 1.67
hope this helps :)
Answer:
Step-by-step explanation:
Given that:
Batting average = 0.25 after 160 times at bat;
Batting Average = Number of hits / number of times at bat
0.25 = number of hits / 160
Number of hits = 0.25 * 160 = 40
He want batting average to improve to 0.333 ; if he makes hit the next x times at bat ; number of hits is needed to improve batting average
Hence,
New average = number of hits / number of times at bat
0.333 = (number of hits + x) / (160 + x)
0.333 = (40 + x) / (160 + x)

How deep is the cake batter?
Answer:
3.3 cm
Step-by-step explanation:
Given that the cake pan is a right rectangular prism 20cm by 28cm.
Now, Whitney puts 
of batter into the pan, we are to determine how deep the batter is.
Volume of a rectangular prism=Length X Width X Height
Volume of the batter = 20 X 28 X Height
1848 =560 X Height
Height =1848/560
Height=3.3cm
Therefore, the cake batter is 3.3 cm deep.
