A’B’ and AB are equal in lenght
When we rotate an object it’s length does not chance only it’s position.
(270 degrees it means you rotate 3 times)
Answer:
She has 16 brownies
Step-by-step explanation:
Initially cut rectangular pan in to two halves.
Then cut each half in half again.
Now total pieces = 4
Now repeat cutting half on other side:
total pieces =8
Now divide each half into another half.
total pieces = 8 x 2 = 16
As can be shown in figure:
Black = first half
pink = dividing each half into another half.
Number 5 should be no solution becuase the n's cancel out.
For 6:
Part A is -2 because slope represents the change in weigh/change in time (-2/1 or -2)
Part B is y=-2x+231 (-2 is the slope and 231 is the y-intercept)
For part C, based on the slope, we can find that her weight will go below 200 at week 16 when it is 199
Hope this helps!
Answer:
The statistical test to use in comparing the number or words spoken for people with and without licenses is independent sample t test.
Step-by-step explanation:
The sample test to use is an Independent Samples t Test. The reason for using this statistical test is because it takes two independent groups; calculates and compares the means of these groups so as to determine if statistical evidence exists such that the associated population means are significantly different.
In this case, there are two groups of passengers (40, in total);
Group 1 are those who have driving licence while group 2 are those who do not.
Depending on the response from these two groups, the independent sample t test calculates the mean and compares the number or words spoken for people with and without licenses to know passengers experience.
