Answer:
Yes
Step-by-step explanation:
[tex]3\frac{1}{6}[/tex] + [tex]5\frac{7}{8}[/tex]
When adding two fractions, both denominators must be the same
To do this, multiply [tex]3\frac{1}{6}[/tex] by 4 to make it into [tex]3\frac{4}{24}[/tex]
And multiply [tex]5\frac{7}{8}[/tex] by 3 to turn it into [tex]5\frac{21}{24}[/tex]
The new equation is:
[tex]3\frac{4}{24}[/tex] + [tex]5\frac{21}{24}[/tex] = 8[tex]\frac{25}{24}[/tex]
Since you can make a whole number from [tex]\frac{25}{24}[/tex], the number 8 becomes a 9
and the new answers becomes [tex]9\frac{1}{24}[/tex]

For f (x) = 2x+1 and g(x) = x2 - 7, find (fºg)(2).
Answers
Answer:
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8

In the year 2005, a person bought a new car for $24500. For each consecutive year
after that, the value of the car depreciated by 9%. How much would the car be worth
in the year 2008, to the nearest hundred dollars?
Answers
because, in three years it would have depreciated by 18% (9%*3=18) so you would subtract 18% off of $24500
Answer:
18500
Step-by-step explanation:
Percent decrease:
\text{Multiply by }(1-r)=(1-0.09)=(0.91)
Multiply by (1−r)=(1−0.09)=(0.91)
2005: \color{green}{24500}
2005:24500
2006: \color{green}{24500} (0.91) = \color{blue}{22295}
2006:24500(0.91)=22295
2007: \color{blue}{22295} (0.91) = \color{red}{20288.45}
2007:22295(0.91)=20288.45
2008: \color{red}{20288.45} (0.91) = \color{orange}{18462.49}
2008:20288.45(0.91)=18462.49

A group of veterinary researchers plan a study to estimate the average number of enteroliths in horses suffering from them. Previously research has shown the variability in the number to be σ = 2. The researchers wish the margin of error to be no larger than 0.5 for a 99% confidence interval. To obtain such a margin of error the researchers need at least:
A. 53 observations.
B. 107 observations.
C. 106 observations.
D. 54 observations.
2.
A group of veterinary researchers plan a study to estimate the average number of enteroliths in horses suffering from them. The number of enteroliths is determined by surgery or ultrasound. This requires the participation of a radiologist and a surgeon in the study. The researchers decide that they should only enroll horses seen at the best veterinary hospital in the country to ensure correct counts. Such a hospital will typically see the most severe cases. The researchers will enroll the first 100 horses seen beginning on the day the study is funded. The resulting interval is likely biased because:
A. the first 100 horses seen is not an SRS of all horses with enteroliths and therefore never representative.
B. a sample of 100 horses is too small to obtain an unbiased estimate.
C. the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths.
D. All of the above

This requires the participation of a radiologist and a surgeon in the study. The researchers decide that they should only enroll horses seen at the best veterinary hospital in the country to ensure correct counts. Such a hospital will typically see the most severe cases. The researchers will enroll the first 20 horses seen beginning on the day the study is funded. The researchers will calculate a 95% confidence interval. The procedure is not valid because the:
A. sample size is too small for the central limit theorem to apply.
B. average number is not an integer and does not reflect any actual observation.
C. None of the above. The procedure is valid.
D. data are counts and, therefore, not Normally distributed.
4.
In a test of hypothesis for a mean, which statement is CORRECT?
A. The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.
B. As long as the population distribution consists only of positive values, sample size does not matter.
C. The population distribution can be any distribution because the sample mean is always Normally distributed.
D. The population must be normal because that is the only case when the sample mean is Normally distributed.
5.
A "false negative," in which no effect is detected when in reality one exists, is an example of:
A. a Type I error.
B. the power of the test.
C. a Type II error.
D. None of the above
Answers
Answer:
1.) 107 observations
2.) the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths
3.) A. sample size is too small for the central limit theorem to apply.
4.) The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.
5.) a Type I error
Step-by-step explanation:
n = [(Zcritical * σ) ÷ E]²
n = sample size
Zcritical at 99% = 2.58
E = error margin = 0.5
Standard deviation, σ = 2
n = [(2.58 * 2) ÷ 0.5]²
n = [5.16 ÷ 0.5]²
n = (10.32)²
n = 106.5024
n = 107 observations
B.) The thought or decision that the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths will introduce a bias in the study.
C.) For central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30
D.) Distribution must be normal it approximately normal, obeying the central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30
what is the density of the oak board? it is 5.5 inches wide, 1.5 inches thick and 3 feet long
Answers
multiply 5.5 the width with 1.5 by 3 which gives you 24.75 inches feet long.
5.5 x 1.5 x 3=24.75 that's your answer.
Answer:297 cubic inches, other person is incorrect.
Step-by-step explanation:5.5 inches* 1.5inches * 3 feet
Convert 3 feet to inches and you have 36 inches. So now it becomes 5.5inches*1.5inches*36inches = 297 cubic inches

Chicago, Illinois has an elevation of 600 feet. Seely, California is -200 feet. What does 0 represent in the context of this situation?
Answers
Answer:
Sea level
Step-by-step explanation:
In geography, 'Elevation' is measured in relation to sea level, so sea level would be zero.
Thus, Chicago is 600 feet above sea level and Seely, California is 200 feet below sea level.
If there were nothing but flat land all the way from Seely to the ocean, sea water would come in and cover Seely. Fortunately for the people in Seely. California's coastal mountain range is between the town and the ocean, so that does not happen.
Answer:
It represents the "SEA LEVEL"

The function h is defined by the following rule.
Find h(x) for each x-value in the table.
Answers
Answer:
64, 8, 1, 1/8
Step-by-step explanation:
So for -2 you have h(-2) = [tex](\frac{1}{8})^{-2}[/tex] to make the power a +2 just flip it so (8/1) which is 8, so now you have [tex]8^{2}[/tex] = 64
Do the same for -1 so h(-1) = [tex](\frac{1}{8})^{-1}[/tex] = [tex]8^{1}[/tex] = 8
Anything to the zero power is = 1 so h(0) = 1
(1/8)^1 is just [tex]\frac{1}{8}[/tex]

---the system of simoultanious equation
X+2y+z=6
2x+y+2z=6
X+y+z=5
Answers
Answer:
The system of equations has no solution.
Step-by-step explanation:
Let the following system of linear equations:
[tex]x +2\cdot y + z = 6[/tex] (1)
[tex]2\cdot x + y + 2\cdot z = 6[/tex] (2)
[tex]x + y + z = 5[/tex] (3)
Since the quantity of equations and variables are the same, there is only one solution to this system. First, we clear [tex]x[/tex] in (3):
[tex]x = 5 - y - z[/tex]
And make substitution both in (1) and (2):
[tex](5-y-z) +2\cdot y + z = 6[/tex]
[tex]2\cdot (5-y-z)+y+2\cdot z = 6[/tex]
[tex]y = 1[/tex] (4)
[tex]y = 4[/tex] (5)
Which lead to a contradiction, since [tex]4\ne 5[/tex]. Therefore, the system of linear equations has no solution.

Answers
Answer:
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees. Both angles are 36 degrees so that's 72 degrees.
Angle L = Angle J (Opposite angles are equal)
Angle L = 98
Angle K + Angle L = 180 (Adjacent angles are supplementary)
Angle K + 98 = 180
Angle K = 180 - 98
Angle K = 82
Angle M = Angle K (Opposite angles are equal)
Angle M = 82
