Answer:
Rounding to the nearest cent, it cost $30 per gallon.
18 = .75x
/.75 /.75 (divide both sides by .75 to isolate x)
24 = x
24 total students
Hope this helps!
Hey there! I'm happy to help!
We want to figure out what x is. Let's use a trigonometric ratio of our 35 degree angle to find it.
We see that x is opposite of the 35 degree angle. We also see that our hypotenuse 4.1 m. The hypotenuse is always across from the right angle.
The trigonometric ratio that deals with opposite and hypotenuse is the sine, which is the opposite divided by the hypotenuse. This gives us the following equation.
We want to solve for x, so we simply multiply both sides 4.1
If we evaluate this on our calculators, we get 2.351663389......
We round this to the nearest tenth, giving us 2.4 m.
Have a wonderful day! :D

Step-by-step explanation:
Answer:
P(a junior or a senior)=1
Step-by-step explanation:
The formula of the probability is given by:
P (AB) = P(A)
Where P(A) is the probability of occurring an event A, n(A) is the number of favorable outcomes and N is the total number of outcomes.
In this case, N is the total number of the students of statistics class.
N=18+10=28
The probability of the union of two mutually exclusive events is given by:
Therefore:
P(a junior or a senior) =P(a junior)+P(a senior)
Because a student is a junior or a senior, not both.
n(a junior)=18
n(a senior)=10
P(a junior)=18/28
P(a senior) = 10/28
P(a junior or a senior) = 18/28 + 10/28
Solving the sum of the fractions:
P(a junior or a senior) = 28/28 = 1
