A large western state consists of 3744 million acres of land. Approximately 89% of this land is federally owned. Find the number of acres that are not federally owned.
411.84 million acres
Step-by-step explanation:Hi there !
100% - 89% = 11% (not federally owned)
3744 m ............ 100%
x m........................11%
x = 11×3744/100
= 41184/100
= 411.84 million acres are not federally owned
Good luck !

Complete each trinomial such that it can be rewritten in the form a(x+b)^2 or a(x-b)^2
1.5x^2+6x+...
Answer:
[tex]1.5x^2+6x+6[/tex]
Step-by-step explanation:
Collect 1.5 from everything, noticing that [tex]6= 1.5\times 4)[/tex]
[tex]1.5(x^2+4x + b^2)[/tex]
Now let's remember that the square of a binomial is [tex](x+b)^2 = x^2+2xb+b^2[/tex], confronting with what we have inside the bracket, [tex]2bx = 4x \implies b=2[/tex]
Our completed bynomial becomes [tex]1.5(x^2+4x+4) = 1.5x^2+6x+6[/tex]
Answer:
1.5x² + 6x + 6
Step-by-step explanation:
1.5x² + 6x + ? = a(x + b)²
a = 1.5
2ab = 6
ab = 3
b = 3/1.5
b = 2
So, inputting all the values :-
a(x + b)²
1.5(x + 2)²
1.5(x² + 4x + 4)
1.5x² + 6x + 6
1. The National Institutes of Health funded a study of a random sample of 856 people
age 71 and older in the United States. They found that 9.7% of these people suffer

from Alzheimer's Disease.
a. Identify the population of interest in this study.
b. Is .097 (the decimal version of 9.7%) a parameter or a statistic? What symbol
do
you use to represent it?
c. Determine a 95% confidence interval for the proportion of elderly Americans
who have Alzheimer's disease.
d. Check and comment on whether the technical conditions required for this
(
confidence interval are satisfied.
e. If you were to determine instead a 90% CI, how would it differ and
how would it be similar to the result in part c? (Do not bother to do the
calculations.)
f. Determine how many people would have to be studied in a new sample if
you want to estimate the population proportion to within = .02 with 99%
confidence. (Use the result of the current sample in your determination of the
new sample size.)
The population in the study are the people that are 71 years of age and older in the United States.
What is a population?Population simply means the representative sample of a larger group. Here, the population in the study are the people that are 71 years of age and older.
Also, 0.097 is a statistic because it describes the proportion of the people that suffer from the disease for the sample of 856.
The technical conditions are that the sample should be collected from a normal distribution. In this case, since the sample size is large, then the sampling distribution of the sample means is normal.

Answer:
Second option from the top
Step-by-step explanation:
First, let us simplify x + 2 < -3
x + 2 < -3
x + 2 - 2 < -3 - 2
x < -5
Now we can more clearly see which graph is correct.
-> Since we are using < / > and not ≤ / ≥ the dot will be opened and not closed. This rules out the first and third options.
-> Next, we need the direction of the line. Since < is facing to the left, our line will also be going to the left.
-> To satisfy all requirements, since all graphs start at -5 already, the correct answer is the second option from the top.
Answer:
it's the second one
Step-by-step explanation:
it's all just common knowledge
the sign is a less than sign so the sign is an open dot. That eliminated two options. And whatever way the less than sign is pointing is the way the arrow goes

What is the slope intercept form of (-4,-5); and slope 1/2
Answer:
[tex]y=0.5x-3[/tex]
Step-by-step explanation:
Given the following question:
Point A = (-4, -5) = (x, y)
[tex]m=\frac{1}{2} =0.5[/tex]
To find the slope intercept form of the given information we will have to use the formula y = mx + b where m equals the slope.
[tex]y=mx+b[/tex]
[tex]-5=0.5(-4)+b[/tex]
[tex]0.5\times-4=-2[/tex]
[tex]-5=-2+b[/tex]
[tex]-2+2=0[/tex]
[tex]-5+2=-3[/tex]
[tex]b=-3[/tex]
[tex]y=0.5x-3[/tex]
Which means your answer is "y = 0.5x - 3."

Which of the following would be a correct interpretation of a 99% confidence interval such as 4.1<μ<5.6?
Choose the correct answer below.
A.
It means that 99% of all data values are between 4.1 and 5.6.
B.
There is a 99% chance that μ will fall between 4.1 and 5.6.
C.
It means that 99% of sample means fall between 4.1 and 5.6.
D.
We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of μ.
Explanation:
Imagine you randomly selected n items to form a sample, and you did this 100 times. Each time doing a trial like this, we generate a confidence interval. We expect about 99 of those times to have a confidence interval containing the true value of μ. This is what it means when we say "We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of μ."
Help please I don’t understand
Answer:
Step-by-step explanation:
Given the following 3 points:
x y
-56 66
-42 58
-28 50
Check the slope of two line segments between the three points:
(58 - 66)/(-42 - (-56))
= -8/14
= -4/7
(50 - 58)/(-28 -(-42))
= -8/14
= -4/7
As the slopes are the same, the 3 points are on a straight line with slope of - 4/7:
y = -4x/7 + C
Substitute x = -28 , y = 50 into the equation
50 = -4(-28)/7 + C
50 = 16 + C
C = 34
y = -4x/7 + 34
Y-intercept at x = 0:
= 34

find the value of mn if ab= 9cm, bc= 7.2cm, and LM= 12cm
Answer:
9.6 cm
Step-by-step explanation:
Since the shapes are similar, we can write a proportion. Let x be the length of MN.
9/12 = 7.2/x Write a proportion.
9x = 12(7.2) Use cross products.
9x = 86.4 Multiply.
x = 9.6 Divide both sides by 9.
Side MN is 9.6 cm.
