4/3x
Step-by-step explanation:
Answer: 7 candy bars
Step-by-step explanation:
First we need to subtract the cost of the magazine from the total cost
$34-$6=$28
Now the $28 that remains is the cost of all the candy bars, so if we divide by the price, we will get the amount.
$28/$4=7 candy bars
Answer:
The expression that represents his total time is given by "t = 7.5/s" where s is his speed against the wind.
Step-by-step explanation:
In order to solve this problem we will assign a variable to Curtis speed on the first leg of the trip, this will be called "s". Since the speed on the first part is "s" and the speed on the second part is 20% higher, then the speed on the second part is "1.2s". Each leg of the course is 9 miles long, therefore the time it took to go each way is given by:
time = distance/speed
First part:
t1 = 9/s
Second part:
t2 = 9/1.2s = 7.5/s
The expression for the whole course is the sum of each, so we have:
t = t1 + t2
t = 9/s + 7.5/s
t = (9 + 7.5)/s = (16.5)/s
Answer:
Step-by-step explanation:

</em>
- <em>Consider a t distribution with 24 degrees of freedom. Compute P(-1.27˂t˂1.27) . Round your answer to at least three decimal places.
</em>
- <em>
</em>
- <em>Consider a t distribution with 5 degrees of freedom. Find the value of c such that P(t≤c)=0.05 . Round your answer to at least three decimal places.</em>
The area of a circe is π*r²
you are given that diameter=30 feet and the radius is half the diameter
so the area is
π*15² = 706.86 ft²
