Answer:
D. Grant did not regroup the 4 tens when he subtracted 7.
Step-by-step explanation:
In the process of subtraction, regrouping is important so that each digit in the given numbers are placed appropriately before the required arithmetic operation is performed.
The correct step to Grant's solution are:
360 - 100 = 260
260 - 20 = 240
240 - 7 = 233
Grant's final answer ought to have been 233.
Going through his solution, he made a mistake while subtracting 7 from 240. He failed to regroup the 4 tens when he subtracted 7 from 240. Thus the essence of his wrong answer.
The mean of a dataset is the sum of all data elements divided by the count of the elements.
The location of the 6th score relative to the mean is 5 points below the mean
Let:
<em> Mean</em>
<em> 5 scores</em>
<em> 6th scores</em>
Given that:

The 5 scores that are 1 above the mean implies that:

The mean of a dataset is calculated using:

So, we have:


Open brackets

Multiply both sides by 6

Make b the subject


This means that the 6th score is 5 points below the mean

The time(h), would be the independent variable and the temperature(C) would be the dependent variable.
Answer: 93
Step-by-step explanation:
To solve this we need to follow BIDMAS.
The order of calculations is brackets, division, then multiplication, then addition, then subtraction.
1) (4 + 3) = 7
2) Division: 8 / 2 = 4
3) Multiplication: 3 * 32 = 96
This leaves us with:
96 + 4 - 7
This equals 93.
