To answer this problem, you have to have a good foundation in factoring polynomial expressions. It has to be taken into account the knowledge in division and fractions.
The expression
(y+7)^2 - 100
can be factored as
[ (y+7) + 10 ] [ (y+7) - 10 ]
Further simplifying the expressions
[ y + 7 + 10 ] [ y + 7 - 10 ]
( y + 17 ) ( y - 3)
So the product of two linear binomials is
(y+17)(y-3)
Answer:
The confidence interval is given for this case
And we can conclude that the true proportion of all American River College students who drink coffee on a regular basis is between 0.262 and 0.438 with a confidence of 0.95
Step-by-step explanation:
For this case we want to determine the confidence interval for the proportion of all American River College students who drink coffee on a regular basis and is given by thsi general formula:
The confidence level for this case is 0.95 and the significance level is and the critical value for this case is
The confidence interval is given for this case
And we can conclude that the true proportion of all American River College students who drink coffee on a regular basis is between 0.262 and 0.438 with a confidence of 0.95
Answer: <u>Acute and Obtuse</u>
Explanation:
The acute angle is the small angle that is less than 90°, and the obtuse angle is the bigger angle. It is more than 90° and is also less than 180°.
Hope this helps!
The questions are all obtuse.
Answer: John must make at least 44 tips to reach his goal.
Step-by-step explanation:
Let x represent the number of tips that John must make this week to reach his goal.
John works at a restaurant and gets paid $80 per week plus $5 per tip. This means that the total amount that John would earn in a week if he makes x tips would be
80 + 5x
This week, John wants to earn at least $300. This is expressed as
80 + 5x ≥ 300
5x ≥ 300 - 80
5x ≥ 220
x ≥ 220/5
x ≥ 44
Answer:
It would be a=1 b=7, a=1 b=120, a=1 b=25, a=1 b=2.5
Step-by-step explanation:
Here you can see that 2 = 14 now if u think about it u can just divide 14 and 2 which you will get 7 which means a=1 and b=7 now for the other questions its all the same just divide
