At 10:00 a.M., Han and Tyler both started running toward each other from opposite ends of a 10-mile path along a river. Han runs

ehidna [41]

Answer: 1. Han run 2.5 miles after a half hour.

2. No, they will not meet within 1 hour.

Step-by-step explanation:

Here, Han runs at a pace of 12 minutes per mile.

Or, we can say that he can run with the speed of 5 miles per hour. (because, speed = 1/pace and 12 minutes = 1 miles ⇒ 60 minutes = 5 miles)

Similarly, If Tyler runs at a pace of 15 minutes per mile ⇒ Tyler run with the speed of 4 miles per hour.

Therefore,

1) The distance covered by Han in half an hour = 1/2 × 5 = 2.5 miles

(because distance = speed × time)

Now, 2) the time at which Han and tyler will meet,

T= Total distance/ ( the sum of their speed)

$T= \frac{10}{5+4} = \frac{10}{9}$

⇒ $T = 1\frac{1}{9}$ hours > 1 hour

That is, they will not meet within 1 hour.

According to a U.S. news poll, 38% of students in the class of 2013 had done an internship during their time as an undergraduate

11Alexandr11 [23.1K]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Percentage of students in the class of 2013 has done an internship during their time as an undergraduate student = 38% = p₀

Number of architecture majors = 100

We need to check that whether students at her university had an internship rate that was higher than the national average.

Proportion for her university = 43% = p₁

Here, n = 100

Since n > 30.

so, we can use z-test.

Z-test is generally use to identify whether two means are different when the standard deviation is given.

Hence, it is safe to use the z-test for p.

Therefore, option 'a' is correct.

which shape had a larger area: a rectangle that is 7 inches by 3/4 inch, or a square with side length of 2.5 inches? Show your r

Brums [2.3K]

In order to find the area for a rectangle, you must multiply length times width, which would be 7 x 3/4 which is 5.25. In order to find the area for a square, you do length^2, also know as length x length. Which would be 2.5^2 which is 2.5 x 2.5 which is 6.25. 6.25 is larger than 5.25, so the square has a larger area.
