The results of a poll show that between 43% and 55% of the population support an increase in sales tax to pay for a new sports stadium.
a) What is the point estimate?
b) What is the margin of error?
Answers
Answers:
a) The point estimate is 49%b) The margin of error is 6%==========================================================
Explanation:
The point estimate is the midpoint of the two ends. We add up the endpoints and divide by 2 to get the midpoint. We have p = 0.43 and q = 0.55, so we get the midpoint (p+q)/2 = (0.43+0.55)/2 = 0.98/2 = 0.49, then this converts to 49%. Meaning 49% is exactly at the midway point of 43% and 55%
---------
The margin of error is the distance from the midpoint to either endpoint. If we try to aim for 49%, but have some error, then we have an error of 55-49 = 6%, or we could say 49-43 = 6%; either way the margin of error is 6 percentage points.
The formula we can use is (q-p)/2 where p and q are the left and right endpoints of the interval. So in this case, we'd have,
(q-p)/2 = (0.55-0.43)/2 = 0.12/2 = 0.06 = 6% margin of error
---------
Side note: We can think of it as if 49 is the center and 6 is the radius of the circle. We want to hit the center of the circle, but we have an error of 6 (meaning that's how far we could go in either direction).

Answer:
Your value of z is 71 degrees. The value of x is 11.
Step-by-step explanation:
You can determine the value of z by knowing that z and the 71 angle are vertical angles. Vertical angles are congruent to each other. We know that the x angle and the 71 angle are supplementary, or that they equal 180. So, set up the equations, and solve for x. :

The cost of buying salad from a salad bar is at least $4.50 per pound. Which inequality represents the price per pound of salad?
x ≥ 4.50
x = 4.50
x < 4.50
x > 4.50
Answers
Step-by-step explanation:
We know from the problem that the salad is going to cost at least $4.50 per pound. Therefore, it is entirely possible for the cost to exceed $4.50, but it cannot be lower than $4.50 because then it would not be equal to $4.50.
So, there would be a greater-than sign pointing toward the s (which I seemingly cannot depict on here for some reason...)
Answer: x ≥ 4.50
Because the cost is at least $4.50 per pound

What volume of coppr ( density 8.96g/cm3)would be needed to balance a 2.28 cm3sample of lead (density 11.4g/cm30 on a two-pan laboratory balance
Answers
Answer:
2.9 cm³
Step-by-step explanation:
Note: For the copper and the lead to balance, they must have thesame mass.
Applying,
D' = m'/V.................... Equation 1
Where D' = density of the lead, m' = mass of the lead, V = Volume of the lead.
make m' the subject of the equation
m' = D'V................ Equation 2
From the question,
Given: D' = 11.4 g/cm³, V = 2.28 cm³
Substitute these values into equation 2
m' = (11.4×2.28)
m' = 25.992 g
Similarly,
for copper,
D = m/V............... Equation 3
Where D = density of copper, m = mass of copper, V = volume of copper.
make V the subject of the equation
V = m/D.............. Equation 4
where, m = m' = 25.992 g
Given: D = 8.96 g/cm³
Substitute these values into equation 4
V = 25.992/8.96
V = 2.9 cm³

Last Sunday Lily and Maddie went to Sarah’s Sweet Shop and purchased one cupcake and one brownie. Their bill was $4.50.
The next day they brought their friend Jessica and purchased 3 cupcakes and one brownie. This time their bill was $9.50.
Let x represent the price of each cupcake.
Let y represent the price of each brownie.
2.The first equation in the system is: x+y=4.50x+y=4.50
3.The second equation in the system is : 3x + y = 9.50
4.Solve the system from question 3 to find the price per cupcake.
5.Find the price per brownie.
6.Find the total cost to purchase 4 cupcakes and 4 brownies from the shop.
Answers
Answer:
Each cupcake cost $2.50 and each brownie cost $2.00
Step-by-step explanation:
Let x represent the price of each cupcake and let y represent the price of each brownie.
Lily and Maddie bought one cupcake and one brownie for $4.50. Hence the equation is:
x + y = 4.50 (1)
Also Jessica purchased 3 cupcakes and one brownie for $9.50. Hence the equation is given by:
3x + y = 9.50 (2)
To find the price of each cupcake and brownie, we solve equation 1 and 2 simultaneously. To find x, subtract equation 1 from equation 2:
2x = 5
x = $2.50
Put x = $2.50 in equation (1):
2.50 + y = 4.50
y = $2.00
Therefore each cupcake cost $2.50 and each brownie cost $2.00

slope.
Answers
Step-by-step explanation:
would you still like me to help you with this question
Angle of depression of the slope is 24. degree.
Angle of depression is equal to the angle of elevation.
sine = the vertical drop/ the ski slope
sine = 100/250
= 2/5 = 0.4.
sine - 1 (0.4) = 23.57 which is about 24 degree.
Therefore, the correct angle of depression of the slope is approximately 24 degree.
