Answer:
The answer is 154.8 ml
Step-by-step explanation:
In this question, the amount of pure acid is 18% of the total solution, that is, 18% of 860 milliliters. So
0.18*860 = 154.8 ml
The answer is 154.8 ml
Answer:
By using completing the square method, equation (x - 12) (x + 4) = 9 can be solved as x = (4 + √ 73) or (4 - √ 73)
Answer:
x is three the ratio show you what you need to divide by so triangle a is 3 and triangle b is 8 times larger than triangle a.
Step-by-step explanation:
Answer:
x = 12 hrs to fill the pool
Step-by-step explanation: INCOMPLETE QUESTION
Missed information:
Time for two different sizes hoses to fill a small simming pool (let say that is 3 hours)
Time for one of the two hoses to fill a small simming pool ( lt say that is 4 hours)
With that information we can answer the question
If one of the hoses fill the pool in 4 hours, it will fill 1/4 of the pool in 1 hour
We dont know the other hose how long it take to fill the pool so let call that time x hours then in 1 hour it will fill 1/x of the pool
In 1 Hour the two hoses will fill 1/3 of the pool then
In one hour
1/4 + 1/x = 1/3 Solving for x
( x + 4 )/ 4x = 1/3
3x + 12 = 4x
- x = -12 x = 12 hours
Answer:
e. Two-sample t-test.
Step-by-step explanation:
This is simply because you only have interval level of measure and you are comparing two populations.
Moreso, this hypothesis test is used to determine questions related to the mean in situations where data is collected from two random data samples. The two sample T-test is often used for evaluating the means of two variables or distinct groups, providing information as to whether the means between the two populations differs. It also can be used to compare the responses of males and females who have each received different treatment within an experiment.
