Lindsey and Justin must survey a random selection of two girls and two boys for each 7th grade class to get the most accurate results, so the correct choice is B.
StatisticsThis is so because, since precise information is required regarding a particular group of students (7th graders), it would be correct to target members of that group to obtain the first samples of information.
That is, by going to the most reliable source, a more reliable sample would be obtained.

(9,7) and K(5, 3) are the endpoints of a line segment. What is the midpoint M of that line
segment?
Write the coordinates as decimals or integers.
M=
Answer:
Step-by-step explanation:
The midpoint of any line segment is the average of the coordinates of the endpoints.
mp=((x2+x1)/2, (y2+y1)/2), in this case we have points (9,7) and (5,3) so
mp=((9+5)/2, (7+3)/2)
mp=(7,5) (x=7 and y=5)

Zoey inflated 24 balloons for the high school dance. If Zoey inflated 15% of the total number of balloons at the dance, how many balloons are there total?
Answer:
Total number of balloons= 160
Step-by-step explanation:
Giving the following information:
Number of balloons inflated by Zoey= 24
Proportion of balloons inflated= 15%
To calculate the total number of balloons, we need to use the following formula:
Total number of balloons = Number of balloons inflated by Zoey / Proportion of ballons inflated
Total number of balloons= 24 / 0.15
Total number of balloons= 160

Brianna has $37 in her checking account. She deposits $150. Then she writes a check for $61. How many dollars does she have in her checking account now?
Answer:
$126
Step-by-step explanation:
A deposit adds money into your checking account, so add $150 to $37.
150+37=187
If you write a check, you take money out, so subtract $61 from $187
187-61=126
Your final answer is $126. Hope this helps!

Which item in nature does NOT follow the Fibonacci Sequence *
Pinecone
Artichoke
Nautilus Shell
Pineapple
Answer:
all follow the sequence
Step-by-step explanation:
Pinecone and Pineapple - Scales and bracts are modified leaves, and the spiral arrangements in pine cones and pineapples reflect the spiral growth habit of stems. To confirm this, bring in a leafless stem from some tree or shrub and look at its buds, where leaves were attached.
Artichoke - The spiral of an artichokes leaves can be described by the Fibonacci Sequence. This sequence is a simple mathematical pattern where each successive number in the sequence is equal to the sum of the two preceding numbers, beginning with 0 and 1.
Nautilus shell - Each number is the sum of the two previous numbers. An approximation of a logarithmic spiral, created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34.
The next day, another group spent a total of $61. Each person in this group paid for general admission, and one person bought a special exhibit ticket. How many people were in this group?
Answer:
3
Step-by-step explanation:
Here is the full question :
This sign shows admission fees and ticket prices for a museum :
General Admission: $18
Tickets to Special Exhibits $7
Tickets to Movies $6
Note: Tickets to the Special Exhibit and the Movie are in addition to the General Admission fee
The next day, another group spent a total of $61. Each person in this group paid for general admission, and one person bought a special exhibit ticket. How many people were in this group?
If only one person bought a special exhibit ticket, the amount spent on general admission = 61 - 7 = $54
Since everyone would have to pay the general admission ticket, we can determine the number of people in the group
number of people in the group = total amount spent on general admission / price of general admission per person
= $54 / $18 = 3

Given:
The equation is:
[tex]3^x\times 9=3^{2n-1}[/tex]
To find:
The value of n in terms of x.
Solution:
We have,
[tex]3^x\times 9=3^{2n-1}[/tex]
It can be written as
[tex]3^x\times 3^2=3^{2n-1}[/tex]
[tex]3^{x+2}=3^{2n-1}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
On comparing the exponents, we get
[tex]x+2=2n-1[/tex]
Add 1 on both sides.
[tex]x+2+1=2n-1+1[/tex]
[tex]x+3=2n[/tex]
Divide both sides by 2.
[tex]\dfrac{x+3}{2}=n[/tex]
Therefore, the value of n is terms of x is [tex]n=\dfrac{x+3}{2}[/tex].

Step-by-step explanation:
On Monday, a museum had 350 visitors. On Tuesday, it had 680 visitors. Estimate the percent change in the number of visitors to the museum. Use pencil and paper. Estimate how many people would have to visit the museum on Wednesday to have the same estimated percent change between Tuesday and Wednesday as between Monday and Tuesday. Explain your answer.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that On Monday, a museum had 350 visitors while on Tuesday, it had 680 visitors. The percent change in the number of visitors to the museum will then be:
= (680 - 350)/350 × 100
= 330/350 × 100
= 94.29%
The number of people that'll have to visit on Wednesday to have the same estimated percent change will be:
= 680 + (94.29% × 680)
= 680 + (0.9429 × 680)
= 680 + 641
= 1321

Use these lengths to find tanx, cosx, and sin x.
Step-by-step explanation:
step 1. tan x = opposite/adjacent = c/b
step 2. cos x = adjacent/hypotenuse = b/a
step 3. sin x = opposite/hypotenuse = c/a
