Answer:

The answer is "0.03125".

Step-by-step explanation:

Two types of undergraduates exist. Its chance for selecting the very first person who is part of degree studies will be 1/2. The probability will also be 1/2 for the 2nd person, as well as, the 3rd, 4th, and 5th person. For 5 random samples, the probability of the graduate therefore is

\to \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} =  \frac{1}{32}=0.03125

Equilateral triangle ABC has a perimeter of 96 millimeters. A perpendicular bisector is drawn from angle A to side BC at point M
a_sh-v [17]

Answer:

16 mm  

Step-by-step explanation:

Since ABC is an equilateral triangle, all three sides are the same length.  The perimeter is found by adding together all of these equal sides; letting x represent the length of a side of the triangle, this gives us

x + x + x = 96

Combining like terms,

3x = 96

Dividing both sides by 3,

3x/3 = 96/3

x = 32

Since AM is a perpendicular bisector, it splits BC into two congruent sections. This means the length of MC, half of BC, will be 32/2 = 16.

Find the values of m and n<br> Need help, thank you!!!
Wewaii [24]

Answer:

m=45 degrees

n=15 degrees

Step-by-step explanation:

m=45 degrees because other 2 angles in it's triangle =90+45=135 degrees

180 degrees in any triangle so m=180-135=45 degrees.

m+n=60 degrees so n=60-45=15 degrees

Identify the initial value in each formula below, and state whether the formula models exponential growth or
kaheart [24]

Answer:

Intial Value: f(t) = 2 , Exponential Growth

Step-by-step explanation:

To find the initial value, all we have to do is find the value of f(t) at t = 0

In this case the given equation becomes

f(t) = 2(\frac{5}{3})^0

from the law of indices we know that any number with the power 0 is equal to 1 (except 0 with the power 0)

a^0 = 1

hence the above equation becomes

f(t) = 2(1)\\ f(t) = 2

so the initial value is 2.

To find out whether this is exponential growth or exponential decay we need to see whether the base value of the power t is less than 1 or greater than 1, i.e. from

(\frac{5}{3} )^t

is

\frac{5}{3} > 1  or \frac{5}{3} < 1

if the value is greater, then with each increment in power, the total value will increase while if it is less than 1 then with each increment in power the total value will decrease.

Hence since \frac{5}{3} > 1 then this is an exponential growth
