Answer:
Option (B)
Step-by-step explanation:
By applying multiplication property of the matrices,
Therefore, system of equations formed will be,
5x + 2y + z = 16
7x - 5y + 2z = 3
-5x + 3y + z = 12
Option (B) will be the correct option.
Answer:
The answer for this question would be 85 and 17/20 or /20
Step-by-step explanation:
You must first find the LCD of these terms (everything that is separated by the addition signs).
The LCD is 20 because:
2 x 10 = 20
5 x 4 = 20
4 x 5=20
and there is no number lower than 20 that all of these numbers share in their multiplication table.
Now you must multiply every term by the number you used to make its denominator 20. Since 2 x 10 = 20, the new term would be:
60 10/20
Since 5 x 4 = 20, the new term would be:
4 12/20
Since 4 x 5 = 20, the new term would be:
20 15/20
Now we put all the whole numbers and numerators together to get:
60 + 4 + 20 = 84 - whole numbers
10 + 12 + 15 = 37 - numerators
84 37/20 = 85 17/20 or 1717/20
After the first 18 years, the population of 1500 will be doubled to 3000.
After the next 18 years, making 36 years total, the population of 3000 will double to 6000.
There are 10 boys because half of 10 is 5 5+5 equals 10
The question requires stating the Null and Alternative hypothesis for the scenario described :
Answer:
H0 : μ = 24
H1 : μ < 24
Step-by-step explanation:
The claim or hypothesis to be tested in a statistical problem or analysis is the alternative hypothesis. This is usually the opposite of the Null hypothesis which is the usually the initial truth until there is significant evidence provided using statistical test to prove otherwise.
The null hypothesis, H0 in the scenario above is :
H0 : μ = 24 ( average battery life is 24 hours)
The alternative hypothesis is the claim, that is. The mean battery life not up to 24 hours ;
H1 : μ < 24
