Semmy [17]

Answer:

.

10% of 50 coins is/are 5 coins.  So, 5 coins are pennies.

40% of 50 coins is/are 20 coins.  So, 20 coins are dimes.

The number of nickels is  (5 + 9) = 14, according to the condition.

Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.

Now you can easily calculate the total and answer the question

   Total = 5*1 + 14*5 + 20*10 + 11*25 = 550 cents = $5.50.     ANSWER

Ryan, a baker, measured the weights of cakes baked in each batch at his bakery and found that the mean weight of each cake is 50
denpristay [2]

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.
