Mary drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 7 hours. When Mary drove h
ELEN [110]
There are two separate equations for this question that use the same variable.

Mary took 7 hours to complete a trip with traffic. This would use the following expression:

7x

Mary took 4 hours to complete the same trip without traffic. The average rate of speed was 27 mph faster than the trip with traffic. This uses the following expression:

4(x+27)

Both trips had the same distance. From the information provided, we can set up the following equation:

7x = 4(x+27)

x represents the average rate of speed on both trips.

Distribute 4 to each term in parentheses:

4 \times x = 4x
4 \times 27 = 108

7x = 4x + 108

Subtract 4x from both sides:

3x = 108

Divide both sides by 3 to get x by itself:

x = 36

The average speed for the slower trip is 36 mph.

We can plug this value into the first equation:

7(36) = 7 \times 36 = 252

Mary lives 252 miles away from the mountains.

It is believed that the average amount of money spent per U.S. household per week on food is about $98, with standard deviation
il63 [147K]

Answer:

yes, we can reject the hypothesis

Step-by-step explanation:

The null hypothesis  

H0 = mean weekly food budget for all households in this community is $98

Let´s find z

z= (x – mean) / standard deviation / √sample size

z = (100 – 98) / 10 / √100

z = 2

Using  a Z table we can find probability  

P (z>2) = 0.0228

Since P < α , results are significant and we can reject the hypothesis
