Answer:
h(-67) = 3158
Step-by-step explanation:
Simply plug in -67 for <em>x</em>:
h(-67) = -49(-67) - 125
h(-67) = 3283 - 125
h(-67) = 3158
Answer:
2 is the correct option.
Step-by-step explanation:
We have the equation
.
We will plot the graphs of the function
and
.
Then, the intersection points of both the graph will be the solution of the equation
.
From the graphs, we see that,
The intersection points of the graphs are (0,1) and (2.337,10.347).
The solution of the equation is the value of 'x' co-ordinate where they intersect.
So, we get, x = 2 is the correct option.
I think it would be $315. i might be wrong tho
Answer:
True, the scores are not valid.
Step-by-step explanation:
The test supposed to be measuring intelligence. We can assume that the intelligence of most people relatively stable (will not change too much over a short amount of time), and can expect it should go upward with brain growth and education. But the test seems to give a huge decrease from the first and second results. Then the third result is a huge increase that even higher than the first test.
We don't know the true value of the subject, but seeing the huge gap for every repetition we can tell that the test result lacks precision.
Answer:
#1
- 150*(1 - 5/8) = 150(3/8) = 56.25
- Option A
#2
- 56.80 + 22.70x = 374.60
- 22.7x = 374.60 - 56.80
- 22.7x = 317.8
- x = 317.8/22.7
- x = 14 months
#3
- Blue = 20 - (9 + 5) = 6
- p(blue) = 6/20 = 0.3 or 30%
#4
- 3 3/4 + 20% of 3 3/4 =
- 3 3/4*1.2 =
- 15/4 * 12/10 =
- 9/2 = 4.5 hr
#5
Actual value = 72 in, expected value = 68 in
- Error = 72 - 68 = 4 in
- Percent error = error/ expected value * 100% =
- 4/68*100% = 5.9% (rounded)
#6
- d + 8% = d + 0.08d = 1.08d
- d*1.08 = 1.08d
#7
<u>Michael</u>
- Data = 42, 43, 45, 4.7, 48
- Mean = (42+ 43+ 45+ 47+ 48) / 5 = 45
- Absolute deviation = (|42 - 45| + |43 - 45| + |45 - 45| + |47 -45| + |48 - 45|)/5 = 2
<u>Nadia</u>
- Data = 36, 37, 46, 50, 51
- Mean = (36+ 37+ 46+ 50+ 51)/5 = 44
- Absolute deviation = (|36 - 44| + |37 - 44| + |46 - 44|+ |50 -44| + |51 - 44|)/5= 6
<u>Nadia had greater mean absolute deviation:</u> 6 - 2 = 4 (seconds)
