The AP Statistics class at the Hallways School for Girls takes a random sample of 50 students (from the school population of 698) and asks them if they get
enough sleep. 18 of the respondents say "yes."
a. Check that all conditions for using the normal approximation to the sampling distribution are met in this scenario.
b. Construct a 95% confidence interval for the proportion of students at the Hallways School for Girls that will say they get enough sleep
c. Before doing this poll, Anna hypothesized that only 25% of all Hallways girls will say they get enough sleep. Based on your data and answer from
part (a) do you think Anna's hypothesis should be rejected? Should it be accepted?
d. If 42% of all girls at Hallways School for Girls would actually say they get enough sleep, what is the probability of getting a sample with as few (or
fewer) "yes" answers as the AP class got?

A friend asked Lara to help her divide 456.3 by 100. What should Lara tell her?
Answer:
Dividing 100 by 456.3 would be 4.563. Lara would need to tell her to look at the zeros, and how many places to move. Dividing by 100 is basically moving the numbers 3 places to the right. Hope this helped ☆

Substitution method of simultaneous equations
3x-4y=7
2x+y=12
Answer: x=5, y = 2
Step-by-step explanation: screenshots
What is the equation for the graph shown?
Answer:
y = 2x/3 + 4
Step-by-step explanation:
The line passes through (-6, 0) and (0, 4)
slope = (4 - 0)/(0 - (-6)) = 4/6 = 2/3
y = (2/3)x + b
when x = 0, y = 4, so
4 = (2/3)*0 + b
b = 4
so
y = 2x/3 + 4

Sw/ati is substituting t = 5 and t = 9 to determine if the two expressions are equivalent.
8 (4t - 3) 32t - 24
Which statement is true?
Both expressions are equivalent to 264 when t = 9.
Both expressions are equivalent to 157 when t = 5.
Both expressions are equivalent to 46 when t = 5.
The expressions are not equivalent.
Answer:
Both expressions are equivalent to 264 when [tex]\displaystyle t = 9.[/tex]
Step-by-step explanation:
All you are doing is substituting 9 for t:
[tex]\displaystyle 8[4(9) - 3]\:32[9] - 24 \\ \\ 264 = 264[/tex]

there was a blizzard. Snow was falling at a rate of 4 1/2 inches per hour. If the snow kept accumulating at the same rate, how long would it take for 5 feet of snow to accumulate?
Answer:
13 1/3 Hours
Step-by-step explanation:
5 feet = 60 inches
4 1/2 inches = 1 hour
60 inches = 1 ÷ 4 1/2 x 60
= 13 1/3 hours
If the snow keeps accumulating, it would take 13 1/3 hours for 5 feet of snow to accumulate.

If a salesman averages a new order every other week, he will break the office record for the year. However, after 32 weeks he is four orders behind schedule. In what proportion of the remaining weeks does he have to obtain a new order to break the record?
The proportion of remaining weeks that he has to obtain a new order to break the record is: 0.7 = 70%.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
He needs a new order every other week, that is, 0.5 orders per week, hence over one year = 52 weeks, the number of orders is:
O = 0.5 x 52 = 26 orders.
Over the first 32 weeks, the expected number was:
E = 0.5 x 32 = 16.
He was four orders behind schedule, that is, he had 12 orders, hence he needed 26 - 12 = 14 orders in the remaining 52 - 32 = 20 weeks, hence the proportion is:
p = 14/20 = 0.7.

Answer:

Step-by-step explanation:
Consider the series.
∞∑n=1 (3^n+1 / 3n+1)
Does the series converge or diverge?
Select answers from the drop-down menus to correctly complete the statements.
Put 1
[tex]\\ \rm\Rrightarrow \left(\dfrac{3^{1+1}}{3(1)+1}\right)[/tex]
[tex]\\ \rm\Rrightarrow 3^2/4=9/4=2.2[/tex]
Put 2
[tex]\\ \rm\Rrightarrow \left(\dfrac{3^{2+1}}{3(2)+1}\right)=3^3/7=27/7=3.8[/tex]
R is
3.8/2.2=19/11Its greater than 1 .
So diverge series.Answer:
[tex]r=\dfrac{12}{7}[/tex]
series diverges
Step-by-step explanation:
To find the common ratio (r) of a geometric series, divide the (n+1)th term by the nth term.
When n = 1:
[tex]a_1=\dfrac{3^{1+1}}{3(1)+1}=\dfrac{3^2}{4}=\dfrac94[/tex]
When n =2:
[tex]a_2=\dfrac{3^{2+1}}{3(2)+1}=\dfrac{3^3}{7}=\dfrac{27}{7}[/tex]
Therefore,
[tex]r=\dfrac{a_2}{a_1}=\dfrac{\frac{27}{7}}{\frac{9}{4}}=\dfrac{12}{7}[/tex]
A series that converges has a finite limit. If |r| < 1, then the series will converge.
A series that diverges means either the partial sums have no limit or approach infinity. If |r| > 1 then the series diverges.
Therefore, as the limit of the series approaches infinity and it's r value is greater than 1, the series diverges.

Use a net to find the surface area of the right triangular prism shown:
Answer:
256 ft²
Step-by-step explanation:
Net comprises: 2 equal triangles, 2 equal rectangles and 1 smaller rectangle
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 10 x 7 = 35 ft²
Area of a rectangle = width x length
⇒ area of larger rectangle = 6 x 12 = 72 ft²
⇒ area of smaller rectangle area = 6 x 7 = 42 ft²
⇒ Total area = (2 x 35) + (2 x 72) + 42 = 256 ft²
