What is the probability that a random selected student at harbor high is 17 years old or older.

Mathematics

Triss [41]3 years ago
4 0

Answer:

See below.

Step-by-step explanation:

The table shows the total number of students as 572 (bottom right cell in the table.)

The number of students who are 17 or older are the students in the two groups: 17-18 and 19-20.

There are 151 students with ages 17-18.

There are 34 students with ages 19-20.

The total of all students 17 or older is 151 + 34 = 185.

The probability of choosing a student age 17 or older is the number of students 17 or older (which is 185) divided by the total number of students (which is 572).

p(17 or older) = 185/572 = 0.3234 = 32.34%

We round 32.34% to the nearest integer to get 32%.

The coordinates of A and B are (3k, 8) and (k, -3) respectively. Given that the gradient of the line segment AB is 3, find the v
Vladimir [108]

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)

You have the set of all the integers from (-16) to 26, inclusive. You take two of the
Vesnalui [34]

The greatest difference you can get is 42

The range of the integer is given as:

Smallest = -16

Largest = 26

So, the range is calculated as:

Range = Largest - Smallest

Substitute known values

Range = 26 - (-16)

Evaluate the difference

Range = 42

Hence, the greatest difference you can get is 42
