X-ounces of an oil blend,
y - ounces of glycerin
x + y = 4 ⇒ y = 4 - x
1.5 x + y = 5.50
1.5 x + 4 - x = 5.50
0.5 x = 5.50 - 4
0.5 x = 1.50
x = 3
y = 4 - 3 = 1
There are 3 ounces of an oil blend and 1 ounce of glycerin.
Solution
Mean = Sum of the numbers / The number of data.
The smallest data can by any value.
The answer is 1) can be any value.
Thank you.
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
The number of freshmen entering college in a certain year = 621
It is considered as discrete data.
Since we know the definition of Discrete which refers to all types of data which take only numerical values.
It is based on counts.
According to question, we have given the exact number of freshmen instead of any range or interval.
Hence, Third option is correct.
Raul took 2 hours and 30 mins to bike 31 1/4 miles. Well 31 1/4 is equivalent to 31.25 and 2hr 30mins is equivalent to 2.5. Now we need to divide the distance by the time to get the rate in mph. 31.25/2.5 = 12.5 So Raul rode at 12.5 miles per hour.
Hey there!!
3 ( x - 6 ) + 15 = 4 ( x - 1 ) + 4
3x - 18 + 15 = 4x - 4 + 4
3x - 3 = 4x
- 3 = x
x = -3
The mistake is , you have written -4 + 4 = 8
- 4 + 4 = 0
and - 18 + 15 = - 3 ( not - 33 )
correct it, you will get it
Hope helps!
