Answer:
its the last one I think.
I will explain this answer with the help of number line which i have shown below.
Considering sea level as starting point i.e origin i will depict how far Trina had gone below sea level and how much Jessie went above sea level.
Distance Traveled by Trina below sea level = - 85.5 meter
Distance Traveled by Jessie above sea level =87.9 meter
Considering sea level as origin i.e 0
Total distance traveled by Trina= 0-(-85.5)=85.5 meter
Total distance Traveled by Jessie = 0+87.9=87.9 meter
So,Trina is nearer to sea level than Jessie.
Now Trina wants to hang glide at the same number of meters above sea level as she scuba dived below sea level.
Then Distance traveled by Trina=85.5 meter
No,she will not fly higher than Jessie because Jessie has traveled 87.9 meter.
Find the mean, median, and mode of the date.<br> 4, 8, 11, 6, 4, 5, 9, 10, 10,4
exis [7]
Answer:
Mean: 7.1, median: 7, mode: 4
Step-by-step explanation:
The mean, also known as the average, is equal to the sum of all the numbers divided by how many numbers there are.
4 + 8 + 11 + 6 + 4 + 5 + 9 + 10 + 10 + 4 = 71
10 numbers
71/10 = 7.1
The median is the number in the middle of the set.
4, 4, 4, 5, 6, 8, 9, 10 ,10 ,11
6 and 8 are in the middle, and the number between 6 and 8 is 7.
The mode of a set of numbers is the most common number. In this case, the number is 4 as it appears 3 times.
Answer:
When you multiply an odd number of negatives you get a negative result. When you multiply an even number of negatives you get a positive result.
First, multiply normally.
25x10x5
1100
Then determine whether the sign is positive or negative. Since there is an odd number of negatives, the sign is negative.
So, the answer is -1100.

Answer:
(a + 4)(a + 6)
Step-by-step explanation:
f(a) = a² + 10a + 24
I think you are asking us to factor the quadratic.
1. Multiply the leading coefficient and the constant
1 × 24 = 24
2. Find two numbers that multiply to give 24 and add to give 10.
Possible pairs are 1, 24; 2, 12; 3, 8; 4, 6
Start with the numbers near the end of the list.
By trial and error, you will find that 4 and 6 work:
4 × 6 = 24 and 4 + 6 = 10
3. Rewrite 10a as 4a + 6a
a² +4a + 6a +24
4. Factor by grouping the first two and the last two terms
a(a + 4) + 6(a + 4)
5. Distribute the a + 4
(a + 4)(a + 6)
a² + 10a + 24 = (a + 4)(a + 6)
