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
Find the slope of the line passing through the pair of points (5,8) (-4,6)
Answer:
0.222
Step-by-step explanation:
the slope of a line is equal to (y2-y1)/(x2-x1)
y1= 8
y2= 6
x1=5
x2=-4
(6-8)/(-4-5)
=0.222

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.

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
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."

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
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."
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

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.
