Answer:
(A)6 kilometers
Step-by-step explanation:
First, we determine the value of a using Pythagoras Theorem.
Therefore:
Distance along the long route = 8 + 15 =23 km
Distance along the shortcut =17 km
Difference =23-17 =6km
Therefore, Mr. Jones bikes 6km less when he takes the shortcut instead of the long route.
Answer:option c is the correct answer.
Step-by-step explanation:
A toaster oven costing $130 offers an extended warranty for 25% of the purchase price. This means that the money value of the warranty is
25/100 × 130 = 0.25 × 130 = $32.5
If the local repair shop will fix a toaster oven for $8, then the number of times that the toaster oven will break in order for the warranty to pay for itself is
32.5/8 = 4.0625
Therefore, it is 4 times
Answer:
d. The mean of the sampling distribution of the sample mean is 140 hot dogs.
Step-by-step explanation:
The number of hot dog vendors sampled is 50
The sample mean of 140 hot dog is obtained by dividing the total number of hot dogs sold by the number of hot dog vendors sampled.
90 + 50 = 140
140 - 7 = 133
130 - 140
