Answer:

The time the patient expected to survive after diagnosis is 29 years.

Step-by-step explanation:

It is provided that the mean survival time after diagnosis for a certain disease is 15 years with a standard deviation of 5 years.

That is,

\mu=15\\\sigma=5

An individual's predicted survival time is <em>a</em> = 2.8 standard deviations beyond the mean.

Compute the time the patient expected to survive after diagnosis as follows:

X=\mu+a\sigma

    =15+(2.8\times 5)\\\\=15+14\\\\=29

Thus, the time the patient expected to survive after diagnosis is 29 years.

Two hikers hike from a first mountain to a second mountain. The next day, they hike from the second mountain to the hollow. The
miskamm [114]

Answer: on the first day, they hiked 9 miles.

On the second day, they hiked 16 miles.

Step-by-step explanation:

Let x represent the distance that the two hikers hiked from the first mountain to the second mountain.

Let y represent the distance that the two hikers hiked from the second mountain to the hollow.

The total distance is 25mi. This means that

x + y = 25 - - - - - - - - - - - - - -1

If the distance between the second mountain and the hollow is 7mi more than the distance from the first mountain to the second mountain, it means that

y = x + 7

Substituting y = x + 7 into equation 1, it becomes

x + x + 7 = 25

2x = 25 - 7

2x = 18

x = 18/2 = 9

y = x + 7 = 9 + 7

y = 16

Colin and Brian were playing darts. Colin scored 141. Brian scored 154 more than Colin. What was their combined score?
Aliun [14]

Answer:436

Step-by-step explanation:

Since Colin scored 141 and Brian scored 154 more than Colin that would be (154+141). So Brian scored 295, so you add Brian's score and Colin's so 295+141, the total score is 436
