Answer:

m(t)  = 10*1.2^{t}  

Step-by-step explanation:

Given that:

  • The initial value: 10 members
  • The base number: 1.2 (increase by 1.2 factor)  

Let m(t) is the number of member in the club, we have the exponential function as:

m(t)  = 10*1.2^{t}

Hope it will find you well.

one angle of a triangle is 2 / 3 of a right angle . the greater of the other to exceed the lesser by 20 degree. Find the angles
jarptica [38.1K]
2/3 of a right triangle is 60 degrees.  Then x + (x+20) + 60 = 180 total.

2x + 80 = 180, so 2x = 100 and x = 50.  The angles are 50, 70 and 60 (degrees)

in a class of 40 students, 24 are over the age of 21 and 16 are 21 or younger. Biff is over the age of 21. A student is selected
LenKa [72]

Answer:

3. 60% probability the student is over the age of 21.4

4. 4.17% probability Biff was selected if you know the student selected was over the age of 21.

5. 0% probability Biff was selected if you know the student selected was 21 or younger

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcoes.

In this question:

40 students

24 over the age of 21.

16 are 21 or younger.

3. Find the probability the student is over the age of 21.

24 of the 40 students are over the age of 21.

24/40 = 0.6

60% probability the student is over the age of 21.4

4. Find the probability Biff was selected if you know the student selected was over the age of 21.

24 students over the age of 21, one of which is Biff.

1/24 = 0.0417

4.17% probability Biff was selected if you know the student selected was over the age of 21.

5. Find the probability Biff was selected if you know the student selected was 21 or younger

Biff is not 21 or younger, he is over 21, so there are no desired outcomes.

So, 0% probability Biff was selected if you know the student selected was 21 or younger

Write an equation in slope-intercept form for the line that passes through the
Pavlova-9 [17]
Make slope intercept
3x - y = 5
3x = y + 5
y = 3x - 5
Parallel = same slope
Slope = 3
Y = 3x + b
Plug in the point
-2 = 3(-1) + b
-2 = -3 + b, b = 1

Solution: y = 3x + 1

Answer:

Jane's situation is the one which represents a porportional relationship.

Step-by-step explanation:

To verify the proportionality betwen a ratio you have to divide all the ratios and all them have to get the same constant factor.

So, if you divide the matt's ratios you aren't gonna find the same constant factor

12/1=12

20/2=10

31/2=15,5

But if you try with Jane's ones:

12/1=12

24/2=12

36/3=12

This 12 is the known constant factor, which show us that these ratios are proportional.
