Answer:
3
Step-by-step explanation:
Using any two pairs from the table if values, say, (5, 16) and (7, 22), the slope of the line is the change in y over change in x.
Thus:
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (5, 16) = (x_1, y_1) [/tex]
[tex] (7, 22) = (x_2, y_2) [/tex]
Plug in the values
[tex] slope (m) = \frac{22 - 16}{7 - 5} = \frac{6}{2} = 3 [/tex].
Slope of the line is 3.

Answer:
g(f(x)) = x² + 6x + 9
General Formulas and Concepts:
Algebra I
Composite FunctionsCombining Like TermsStep-by-step explanation:
Step 1: Define
f(x) = x² + 6x + 7
g(x) = x + 2
g(f(x)) is x = f(x)
Step 2: Find g(f(x))
Substitute: g(f(x)) = (x² + 6x + 7) + 2Combine like terms: g(f(x)) = x² + 6x + 9Two airplanes leave the same airport heading different directions. After 2 hours, one airplane has traveled 710 miles and the other has traveled 640 miles. Describe the range of distances that represents how far apart the two airplanes can be at this time
Answer:
Step-by-step explanation:
710 + 640 = 1350m
There are 125 people on a mountain trail. If 55 people on the trail are children, what percentage of the people on the trail are children?
Answer:
44%
Step-by-step explanation:
.44 x 125 equals 55 n
Answer:
The percentage of people who were children = 44%
Step-by-step explanation:
Total people = 125Children on the trail = 55We need to determine the percentage of the people on the trail who are children.
All we need is to divide 55 by the total number of people i.e. 125 and then multiply the result by 100.so
Children percentage = 55 / 125 × 100
= 0.44 × 100
= 44%
Therefore, the percentage of people who were children = 44%

Find the slope, if it exists, of the line containing the pair of points.
(8,-6) and (3,9)
Answer:
The slope is -3
Step-by-step explanation:
the equation for finding the slope between two different points is:
M= (y2-y1)/(x2-x1)
Or in other words the change in y over the change in x.
M= (9+6)/(3-8) = 15/-5 = -3.
(sidenote: I added 9 and 6 for the change in y because you cannot subtract a negative number. Instead you have to add it.)

Bill and Ted are each saving money for a trip to Europe. Bill started with $75 and saves an additional $15 per week. Ted began with $120 and saves an additional $10 per week. After how many weeks, x, will they have the same amount of money saved? Explain how you arrived at your answer.
Answer:
9 weeksStep-by-step explanation:
After x weeks Bill will save money:
75 + 15xAnd Ted will save:
120 + 10xSince they save same amount, we have equation:
75 + 15x = 120 + 10x15x - 10x = 120 - 755x = 45x = 45/5x = 9 weeksA number with no variable attached is called a what
Answer:
constants
Step-by-step explanation:
That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.
The term or number with no variable attached is called a constant as in the polynomial or expression.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
A number consists of the expression with no variable.
As we know, the expression is a combination of numbers, variables, and operators.
If we take an example of the polynomial.
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm p(x) = a_0+a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
Here a₀ is a constant because the term a₀ has no variables.
Thus, the term or number with no variable attached is called a constant as in the polynomial or expression and the constant value does not change.

If an article was bought for £400 and was sold for £336 what is the loss persentages
Answer:
Hey mate!
Here is your answer > >
C.P of an article=Rs.400
S.P.of an article=Rs.336
C.P.> S.P., there is a loss
Loss=C.P.-S.P.
=> Loss=400-336
=Rs.64
Loss%=Loss/C.P.×100
=64/400×100
=16%

Answer:
The number of yards in 5 miles will be: 8800 miles
Step-by-step explanation:
The double numbers line shows the ratio of yards to miles.From the number line, it is clear that
at 2 miles, the number of yards is 3520.Thus,
The unit rate = 3520 yards / 2 miles
= 1760 yards / per mile
Thus, the number of yards in 5 miles will be:
1760 × 5 = 8800 miles
Therefore, the number of yards in 5 miles will be: 8800 miles

In 1908, W.S. Gossett performed a sleep study on 10 subjects, comparing the number of hours of sleep obtained by each subject with and without (in that order) the application of the drug hyoscyamine. The paired differences d were as follows: 1.0, 0.8, 1.1, 0.1, - 0.1, 4.4, 1.5, 1.6, 4.6, 3.4 At the 1% significance level, is the drug effective in increasing sleep
Answer:
Since the calculated value of t= 2.8782 does not fall in the critical region so we accept H0 and may conclude that the drug is not effective in increasing sleep.
Step-by-step explanation:

∑18.4 ∑59.76
1: We state our null hypothesis as
H0 : μd= 0 against the claim Ha: μd ≠ 0
2: The significance level is set at ∝ = 0.01
3: The test statistic under H0 is
t= d`/ sd /√n
4:The critical region is t ≥ t ( 0.005) 9 = 3.250
5:Computation:
d`= ∑d/n= 18.4/10= 1.84
Sd² = ∑(di- d`)²/n-1 = 1/n-1 [∑di²- (∑di)² /n]
= 1/9 [59.76 - (18.4)²/10]
=(59.76 - 33.856)/9
= 25.904/9
= 2.8782
6: Conclusion:
Since the calculated value of t= 2.8782 does not fall in the critical region so we accept H0 and may conclude that the drug is not effective in increasing sleep.
This is because we have taken H0 as the mean of the difference is zero.
This can only be zero when the drug is not effective.
During a thunderstorm, 4
inches of rain fell in 2 1/2
hours. What was the rate of rainfall in inches per hour?
Answer: 1.6 in per hour
Answer:
hourly rate.
Step-by-step explanation:
As others have noted, it is a simple mathematical division problem (4/2.5) and the average is 1.6 inches per hour.
However, if this is for sizing civil works such as culverts or plumbing storm water drainage systems to mitigate flooding, the highest rate per hour must be known and usually the highest ten minutes rainfall rate expressed as an hourly rate.
For example, if 4.0 inches fell over that 2.5 hours, nothing says that a rain band did not dump 3 inches in the first hour, (3 inches per hour cumulative) or 0.75 inches in a ten minute period (4.5 inches per hour rate), with the remainder of the storm tapering off to lesser rates. So the average is correct, but the peak hour is much more important for practical purposes.

Kevin Fast pulled a CC- 177 Globemaster airplane 8.8m. he plane weighed 188 tons. How many pounds did the lane weigh?
Answer:
376000 pounds
Step-by-step explanation:
What's required of this question is to convert the given weight of plane from tons to pounds
Given
[tex]Weight = 188\ tons[/tex]
Required
Get pounds equivalent
From standard unit of measurements
[tex]1\ ton = 2000\ pounds[/tex]
Multiply both sides by 188
[tex]188 * 1\ ton = 188 * 2000\ pounds[/tex]
[tex]188\ tons = 376000\ pounds[/tex]
Hence, the weight of the plane in pounds is 376000

Answer:
D. x = 3
Step-by-step explanation:
We would like to find out for what value of x does f(x) = g(x). This is essentially the same as asking us to find the x-value for which f(x) = k, where k is some number, and g(x) = k, as well.
Looking at the two tables provided, we notice that when x = 3, both f(x) and g(x) equal -2. So, the answer is D.

In 1923, a certain country underwent one of the worst periods in history of hyperinflation, which is extraordinarily large inflation in prices. At the peak of the hyperinflation, prices rose 11,000% per month. At this rate, by what percentage would prices have risen in 1 year? In 1 day? (Assume 30 days per month.)
The annual inflation rate is ___ x 10 ^ ___%
(Type whole numbers.)
The daily inflation rate is ___ %.
(Round to the nearest whole number as needed.)
Answer: 3.498 * 10^26 % ; 16.9% per day
Step-by-step explanation:
Inflation rate = 11,000 per month
Hence, price after a month :
Final price = initial price (1 + rate)
Final price = 1 + 11000/100
Final price = (1 + 110) * initial price
Final price = 111 times the initial price
Hence inflation over the 12 month period :
(111)^12 = 3.498 * 10^24
(3.498 * 10^24) * 100% = 3.498 * 10^26 %
The daily inflation rate :
Number of days = 30
30th root of 3.498 * 10^24 = 1.169
(1.169 - 1) = 0.169
0.169 * 100% = 16.9% per day
