The sum of two numbers is 80. Their difference is 38. What is the product of these two numbers?
xz_007 [3.2K]

Answer:

The product of these two numbers is 1239.

Step-by-step explanation:

Given that

a + b = 80

a -  b = 38

Add both equation :

a + b = 80

a -  b = 38

2a = 118

a = 59

Put value of a in any 1st equation

a + b = 80

b =  80 - 59

b = 21

<em>Product : </em>

a x b = 59 x 21

        = 1239

A student from the community college is selected at random. Find the probability that the student is between 26 and 35 inclusive
Ksivusya [100]

The question is incomplete! The complete question along with answers and explanation is provided below!

Question:

The age distribution of students at a community college is given below:

Number of students under 21: 416

Number of students 21-25: 402

Number of students 26-30: 210

Number of students 31-35: 55

Number of students over 35: 24

Total number of students: 1107

A student from the community college is selected at random. Find the probability that the student is between 26 and 35 inclusive. Round approximations to three decimal places.

Answer:

Probability of age 26-35 = 0.239 or 23.9 %

Step-by-step explanation:

The no. of students in the age 26-35 = no. of students of age 26-30  + no. of students of age 31-35

The no. of students in the age 26-35 = 210 + 55

The no. of students in the age 26-35 = 265

Total no. of students: 1107

Probability of age 26-35 =  The no. of students in the age 26-35/ Total no. of students

Probability of age 26-35 = 265/1107

Probability of age 26-35 = 0.239

Probability of age 26-35 = 23.9 %

Which of the following graphs best represents the solution to the pair of equations below? y = −x + 6 y = 2x − 3 A coordinate pl
spayn [35]

Answer:

The lines are 

i)  y=-x+6

ii) y=2x-3

The solution of the system of equations is found by equalizing the 2 equations:

-x+6=2x-3

-2x-x=-6-3

-3x=-9

x=-9/(-3)=3

substitute x=3 in either i) or ii):

i)  y=-3+6=3

ii) y=2(3)-3=6-3=3

(the result is the same, so checking one is enough)

This means that the point (3, 3) is a point which is in both lines, so a solution to the system.

In graphs, this means that the lines intersect at (3, 3) ONLY

Answer: The graph where the lines intersect at (3, 3)
