Answer:
(0.46, 0.52)
Step-by-step explanation:
The formula for Confidence Interval with Proportion
CI = p ± z × √p(1 - p)/n
Where
p = Proportion = x/n
x = 346
n = 706
p = 346/706
p = 0.49
z = z score of Confidence Interval 90% = 1.645
Therefore:
CI = 0.49 ± 1.645 × √0.49(1 - 0.49)/706
CI = 0.49 ± 1.645 × √0.49 × 0.51/706
CI = 0.49 ± 1.645 × 0.0188139843
CI = 0.49 ± 0.0309490042
Hence:
Confidence Interval is
0.49 - 0.0309490042
= 0.4590509958
≈ 0.46
0.49 + 0.0309490042
= 0.5209490042
≈ 0.52
Therefore , the confidence interval of the population proportion is
(0.46, 0.52)

4. The total number of tickets sold at the Friday night football game was
1,650. Each adult ticket cost $3.50 and each student ticket cost $2.00.
The total revenue for ticket sales was $4,650. Which system of
equations could not be used to determine the number of adult
tickets, a, and student tickets, s, sold at the game?
a + s = 1650
A) 3.5a + 2s
4650
1650 - Sa
B) 3.5a + 25
4650
a + s = 1650
C) 3.5a - 4650
2s
D) a+s=1650 2a+3.5s= 4650
Answer
a + s = 1,650
3.5a + 2s = 4,650

A soccer coach fills a jug with 10 liters of water before practice. Which object has a volume closest to that of the water jug? coffee mug fish tank soda can swimming pool
Answer:
fish tank
Step-by-step explanation:
Volume refers to the space occupied by an object. The three dimensional measurement is used to find the volume of an object. Length, width and height of the object helps in finding the volume of it.
According to the given question, the volume of a jug with 10liters of water in it will be closest to that of the volume of the fish tank. There are various sizes in which fish tanks are available. From the given options, coffee mug and soda can can be very small to hold a capacity of 10 liters. At the same time, swimming pool will hold water in multiples of 100 liters. Therefore, the most suitable option will be a fish tank.

Need help, please
Given:
The figure of a triangle with mid segment.
To find:
The value of x.
Solution:
According to triangle mid-segment theorem, the mid-segment of a triangle is parallel to the base and the length of the mid-segment is half of the base.
Using the triangle mid-segment theorem, we get
[tex]AB=\dfrac{1}{2}EG[/tex]
[tex]x+14=\dfrac{1}{2}(17+x)[/tex]
[tex]2(x+14)=17+x[/tex]
[tex]2(x)+2(14)=17+x[/tex]
On further simplification, we get
[tex]2x+28=17+x[/tex]
[tex]2x-x=17-28[/tex]
[tex]x=-11[/tex]
Therefore, the value of x is -11.
There are 20 students in the drama club. Next year, 5
students will leave the drama club and some students
will join. If d is the number of students who will join the
drama club, write an expression to represent the total
number of students in the drama club next year.
Answer:
27
Step-by-step explanation:
Let d = number Of drama club members
let y = number of yearbook club members
now you can write two equations, one for the total number of students, and one for the difference between them.
d + y =64
d - y = 10
to solve for d, add these two lines together (so as to remove the y’s)
2d + 0y = 74
d = 37
now substitute back into one of the formulas
d+y=64
37+y=64
subtract 37 from each side,
y = 27
