Answer: d. the census bureau got the result 57,005 plus or minus 742 using a method that will capture the true median income 90% of the time when used repeatedly.
Step-by-step explanation:
No t-value has been included in this interval so it cannot be correctly labeled a confidence interval.
This invalidates options a to c.
Option d is therefore the correct answer because it states that the census bureau simply got those results above without claiming that the results constituted a confidence interval.

Using the graph. which of the following ordered pairs represents solutions to this inequalities? Select all that apply
(0,10)
(5,12)
(8,6)
(10,4)
(12,5)
(15,2)
Answer:
(8,6) and (10,4)
Step-by-step explanation:
solutions to the system of inequalities are in the purple shaded area, coordinates not landing in the purple shaded area are incorrect. The purple shaded area represents solutions for both lines red and blue.
Incorrect answers:
(0,10) because it lands in the blue shaded area ( meaning its the solution for only line blue and not line red)
(5,12) because it lands in the red shaded area ( meaning its the solution for only line red and not line blue)
(12,5) in red only
(15,2) in red only
Use technology to find the P-value for the hypothesis test described below. The claim is that for a smartphone carrier's data speeds at airports, the mean is μ=11.00 Mbps. The sample size is n=14 and the test statistic is t=1.484. P-value=nothing (Round to three decimal places as needed.)
Solution :
The null and alternative hypothesis is given by
[tex]$H_0: \mu = 11$[/tex]
[tex]$H_a: \mu \ne 11$[/tex]
Assume that the level of significance, α = 0.05
The t-test statistics is, t = 1.484
Degree of freedom :
df = n - 1
= 14 - 1
= 13
The P-value is given by
P-value = 2P (T>|t|)
= 2P(T>|1.484|)
= 2P(T>1.484)
= 2(=T.DIST.RT(1.484,13))
= 0.05

Select the statement that describes this expression: 13 + fraction 1 over 2 x (6 ÷ 2 + 6) A: 13 more than half of 6 more than the quotient 6 and 2 B: 13 more than half of the quotient of 6 and 6 minus 2 C:Half of 13 multiplied by the quotient of 6 and 2 plus 3 D:13 plus half of 6 divided by 2, then subtract 6
Answer:
"13 plus half of 6 divided by 2, then add 6"
Step-by-step explanation:
We need to select the statement that describes this expression :
[tex]13+\dfrac{1}{2}\times (\dfrac{6}{2}+6)[/tex]
Here 13 is added to half of 6 divided by 2 and then add 6.
Hence, this is the correct answer "13 plus half of 6 divided by 2, then add 6).

V101.08 is your questions answer
Answer:
10
Step-by-step explanation:
Firstly, check for square roots above and below rt(101) that you know.
Below: rt(100) = 10
Above: rt(121) = 11
As rt(100) is the closest to rt(101), your answer will be 10.
Hope this helps! :D
Hi. Please i need help with this . No jokes .
Answer:
I) The roots are:
First Case:
[tex]x=-2\text{ or } x=-6[/tex]
Second Case:
[tex]x=2\text{ or } x=6[/tex]
II) Possible values of p are:
First Case:
[tex]p=-12[/tex]
Second Case:
[tex]p=4[/tex]
Step-by-step explanation:
We have the equation:
[tex]x^2-(4+p)x+12=0[/tex]
We know that one of the roots is three times the other.
And we want to find the roots of the equation and the possible values for p.
To find our solutions, we can use the process of factoring.
If we have an equation in the form:
[tex]x^2+bx+c=0[/tex]
We want to find two numbers, say, k and j, such that:
[tex]\displaystytle kj=c\text{ and } k+j=b[/tex]
After finding them, we can factor as such:
[tex](x+k)(x+j)[/tex]
So, -k and -j will be our zeros.
Therefore, for our equation, we will find two numbers k and j such that:
[tex]\displaystyle kj=12\text{ and } k+j=-(4+p)[/tex]
Notice that for the first criterion, we can simply list all the factors of 12.
So, according to the first equation, possible values of k and j are:
1 and 12; 2 and 6; or 3 and 4.
Then, our roots will be -1 and -12; -2 and -6; or -3 and -4, respectively.
However, remember that one of our roots is three times the other.
Therefore, the only candidates that work will be the second option.
Hence, k and j are 2 and 6.
Therefore:
[tex]k=2\text{ and } j=6[/tex]
With this information, we can now determine p. Since:
[tex]k+j=-(4+p)[/tex]
Then it follows that:
[tex]\begin{aligned}(2)+(6)&=-(4+p)\\8&=-(4+p)\\-8&=4+p\\p&=-12\end{aligned}[/tex]
Hence, our equation is:
[tex]x^2-(4+-12)x+12=0[/tex]
Or, factored:
[tex]x^2+8x+12=0 \text{ or } (x+6)(x+2)=0[/tex]
So, our roots are x=-6 and x=-2 when p=-12.
However, we also need to consider the negative factors of 12.
Factors of 12 also include -2 and -6.
Hence, our k and j can also be k=-2 and j=-6.
Then, in this case, our p is :
[tex]\begin{aligned} (-2)+(-6)&=-(4+p)\\-8&=-(4+p)\\8&=4+p\\p&=4\end{aligned}[/tex]
Therefore, for our second case, k=-2 and j=-6. Then p=4. So, our equation is:
[tex]x^2-(4+4)x+12=0[/tex]
Or, factored:
[tex]x^2-8x+12\text{ or } (x-2)(x-6)=0[/tex]
Hence, when p=4, our roots are x=2 and x=6.

Answer:
Step-by-step explanation:
1/4a + 1/3a + 8 = 22
Collect like terms
1/4a + 1/3a = 22 - 8
Simplify
3a+4a/12 = 14
7/12a = 14
Divide both sides by 7/12
a = 14 ÷ 7/12
= 14 × 12/7
= 168/7
= 24
a = 24
Check:
1/4a + 1/3a + 8 = 22
1/4(24) + 1/3(24) + 8 = 22
24/4 + 24/3 + 8 = 22
6 + 8 + 8 = 22
22 = 22
