<p><strong>What is the least common denominator for the fractions below? (Round the answer to the nearest integer.)</strong></p>
Correct Answer : C
We determine least common denominator (LCD) using prime factorization of denominators as follows
2=1*2
3=1*3
5=1*5
Thus, LCD of 2, 3, 5 = 2*3*5=30

To find the circumference of the flower bed (which is a circle), you use the formula π×diameter\pi \times \text{diameter}π×diameter. With a diameter of 5 feet and using π≈3.14\pi \approx. 3.14π≈3.14, the calculation is 3.14×5=15.73.14 \times 5 = 15.73.14×5=15.7 feet, which is the required length of the barrier.

To calculate the average rate of change per month, we first determine the total change in the account balance and then divide that by the number of months over which the change occurred.
The change in the balance from March 15 to August 15 is:
Changeinbalance=1450−1140=310
Now, we calculate the number of months between March 15 and August 15:
Numberofmonths=5months
Next, we find the average rate of change per month:
Averagerateofchangepermonth = = 62
Correct Answer is C
Explanation
To solve this problem, we need to find the mean, mode and median of the above data set.
From the data set, the mode of the data is 2 and 8. They are the most occurring elements in the data set.
Mean of data is total divided by number of elements
Total=1+ 1 + 2+ 2+ 2+ 2+ 3 +3+ 7+ 7+8+8+ 8+ 8+ 9+9=80
Number of elements=16
Mean=80/16=5
Median will fall in between the (N/2)th and (N/2+1)th position
(N/2)th =16/2 =8th position and (16/2+1)th =9th position
Since the data is arranged in ascending order as below
1, 1, 2, 2, 2, 2, 3, 3, 7, 7, 8, 8, 8, 8, 9, 9
Element in 8th position = 3
Element in 9th position =7
So median average of the two elements=(3+7)/2=5
Now the data could be presents as follows in the distribution curve
This is because the data set has two modes, meaning the data is bimodal.
Correct Answer is A
Explanation
In direct proportion relation we utilize the relationship as:
Variable∝Variable 2
Thus from the given case,
Force∝stretch
We introduce a constant term, K to remove the sign of proportionality as
Force=K* stretch
Let’s find the value of K, using Force=132 N and stretch of 0.07 m
132 N=K*0.07 m
K=132 N/0.07 m=1885.7 N/m
Now substitute this value of K in the following equation
Force=1885.7 N/m * stretch
For a stretch of 0.1 m, the force needed is
Force=1885.7 N/m * 0.1 m=188.57 N=188.6 N
