<h2>Answer:</h2>
29%
<h2>Explanations:</h2>
Probability is the likelihood or chance that ab event will occur. Mathematically;
Probability = Expected/Total
From the given table, the total number of male student is the total outcome as shown:
Total outcome = 4 +6+ 2 + 2
Total outcome = 14
If a male freshmen is selected at random, the expected outcome will be 4.
Determine the probability
Hence the probability that the male student is freshman is approximately 29%

Answer:
Diameter of the circle is twice it's radius D=2r.
Circumference of the circle is 2πr.
According to the above problem,
<u>2π(radius)</u>=20 inches
2(radius)=20/π=20/3.14
Diameter=<u>6.37 inches</u>
<h3><u>6.37 inches</u> is the right answer.</h3>
Answer:
40 km on the highway
30 km on the city roads
Step-by-step explanation:
Let x = highway
Let y = city road
The time formula: time = distance / speed.
1) Since we do not know the distance travelled on the highway and city roads but we do know the total time taken, we can say x + y = 70. Set the distances x and y and all equated to 2 hours, since we do not know them, nor do we know the time. This is called a system of equations.
x + y = 70
x/80 + y/20 = 2
2) Solve the system of equations using substitution.
x = 70 - y
---------------
70 - y/80 + y/20 = 2
70 + 3y/80 = 2
y = 30
---------------------------------
x + 30 = 70
x = 70 - 30
x = 40
Therefore, the delivery truck travelled 40 km on the highway and 30 km on the city roads.
