There are a couple of things that can help make it easier to construct a table of values.
1) recognize the axis of symmetry for this quadratic is ...
x = -b/(2a) = -25/(2(-5)) = 2.5
So, choosing numbers either side of t=2.5 will cut your work in half.
h(2) = h(3)
h(1) = h(4) . . . for example
2) use Horner form to make manual evaluation easier.
h = (-5t +25)t +2 or = (5 -t)(5t) +2

Based on the average predictions of 50 economists, the U.S. gross domestic product (GDP) will expand by 2.5% this year. Suppose the sample standard deviation of their predictions was 2%. At the 10% significance level, test if the mean forecast GDP of all economists is less than 3%.

Answer:
3:37:43.8
Step-by-step explanation:
The relevant relation is ...
time = distance / speed
time = (700 mi)/(192.9 mi/h) ≈ 3.628823 h
≈ 3:37:43.8 . . . . HH:MM:SS
The driver's time was about 3 hours, 37 minutes, 43.8 seconds.
_____
Additional comment
Multiply 60 minutes by the fraction of hours to get minutes.
60×0.628823 ≈ 37.729393 . . . minutes
Multiply 60 seconds by the fraction of minutes to get seconds.
60×0.729393 ≈ 43.76 . . . seconds

Step-by-step explanation:
how do I add odd number fractions for example 5/9 and 3/5?
Answers
Answer:
if the denominators are not the same, then you have to use equivalent fractions which do have a common denominator. To do this, you need to find at least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with common denominator. Then add and simplify
Answer:
[tex]\frac{52}{45}[/tex] or [tex]1\frac{7}{45}[/tex]
Step-by-step explanation:
In order to add two fractions with different denominators, you will have to find its least common denominator (LCD):
The LCD of 9 and 5 is 45.
Next, we'll start with 5/9:
Divide 45 by 9, which results in 5. Then, multiply the numerator by 5:[tex]\frac{5}{9} = \frac{5*5}{45} = \frac{25}{45}[/tex]
The same goes with 3/5:
Divide 45 by the denominator, 5, then multiply 5 by the numerator 3:
[tex]\frac{3}{5} = \frac{9*3}{45} = \frac{27}{45}[/tex]
Now, we can finally add 25/45 and 27/45 since they have the same denominator. Doing so results in a sum of 52/45:
[tex]\frac{25}{45} + \frac{27}{45} = \frac{52}{45}[/tex]
If you have to transform 52/45 into a proper fraction (which will result in a mixed fraction), then it will be [tex]1\frac{7}{45}[/tex].

The missing value in the ratio that we have in the question is obtained as 54.
What is a ratio?To find the missing value, we can set up a proportion using the given equivalent ratios.
The equivalent ratios are 6:5 and ___:45.
We can write the proportion as:
6 / 5 = ___ / 45
Let the missing number be x in the expression that has been written in the question or problem that we have here thus we have that;
6/5 = x/45
x = 6 * 45/5
x = 54
Thus we would have the missing value that is here as 54.

Rewrite as an exponential equation.
Answers
Step-by-step explanation:
The first technique we will introduce for solving exponential equations involves two functions with like bases. Recall that the one-to-one property of exponential functions tells us that, for any real numbers b, S, and T, where
b
>
0
,
b
≠
1
,
b
S
=
b
T
if and only if S = T.
In other words, when an exponential equation has the same base on each side, the exponents must be equal. This also applies when the exponents are algebraic expressions. Therefore, we can solve many exponential equations by using the rules of exponents to rewrite each side as a power with the same base. Then we use the fact that exponential functions are one-to-one to set the exponents equal to one another and solve for the unknown.
For example, consider the equation
3
4
x
−
7
=
3
2
x
3
. To solve for x, we use the division property of exponents to rewrite the right side so that both sides have the common base 3. Then we apply the one-to-one property of exponents by setting the exponents equal to one another and solving for x:

x
−
7
