Answer:
Remember that £ has a greater value compared to $ and vice versa.
Multiply each number. Remember that when multiplying a negative and positive number, the outcome will be negative
7 x -5 = -35
-35 x 4 = -140
-140 is your answer
hope this helps
Use the formula i = p*r*t.
Here, p = $100000, r = 0.05 and t = 1 (year)
The interest would be i = $100000*0.05*1 = $5000 per year.

Therefore, the simplified expression is:

Answer: Rejecting the mean weight of each cake as 500 gram when H subscript 0 equals 500
Step-by-step explanation:
Given that :
Null hypothesis : H0 =500
Alternative hypothesis : Ha < 500
Type 1 Error: Type 1 error simply occurs when we reject the Null hypothesis when the Null is true. Alternatively, type 11 error occurs when we fail to reject a false null hypothesis.
Hence, in the scenario above, a type 1 error will occur when we reject the mean weight as 500 even though the Null hypothesis is True.
