Carmela randomly selected 85 stamps from a stamp collection. Eleven of these were commemorative stamps.
What is the interval estimate for the proportion of commemorative stamps in the entire collection if the sampling method had a margin of error of ±0.035 ?
(0.075, 0.145)
(0.285, 0.355)
(0.082, 0.089)
(0.095, 0.165)
Answer:
(0.095, 0.165)
Step-by-step explanation:
Confidence interval :
Phat ± margin of error
Margin of Error = 0.035
Phat = x / n
Phat = 11 / 85 = 0.1294117
Hence,
Phat ± 0.035
Lower boundary = 0.1294117 - 0.035 = 0.0944
Upper boundary = 0.1294117 + 0.035 = 0.1644
(0.0944, 0.1644)
Answer:
The answer is (0.095, 0.165)

Sheila threw the discus 24 meters, which was 0.38 meter farther than Tiesha threw the discus. How far, in meters, did Tiesha throw the discus?
Answer:
23.62 meters
Step-by-step explanation:
Find how far Tiesha threw the discus by subtracting 0.38 from 24:
24 - 0.38
= 23.62
So, Tiesha threw the discus 23.62 meters
A milk truck has a diameter of 10 and feet and a height of 50 feet. How much milk can the truck hold?
Answer:
The mentioned milk truck can hold:
3927 ft^3 of milk.Step-by-step explanation:
As you can see, the question is asking about the volume of the milk truck, to obtain the volume of a cylinder, first we must to find the area of the surface side, in this case is a circle, to find the area of a circle when we have the diameter is:
Area of a circle = [tex]\pi *\frac{\ D^{2} }{4}[/tex]Where D is the diameter given (10 feet), now we replace and operate:
Area of a circle = [tex]\pi *\frac{\ (10 ft)^{2} }{4}[/tex]Area of a circle = [tex]\pi *\frac{\ 100 ft^{2} }{4}[/tex]Area of a circle = [tex]\pi *25 ft^{2}[/tex]Area of a circle = 78.54 ft^2 approximatelyNow, with the data of the area, we can calculate the volume with the formula below:
Volume of a cylinder = Area of the circle * heightVolume of a cylinder = 78.54 ft^2 * 50 ftVolume of a cylinder = 3927 ft^3With the calculations, we can see the milk truck can hold 3927 cubic feet of milk with those dimensions.
HURRY PLEASEE!! A new health drink has 140% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 50mg. How many milligrams of the vitamin are in the drink?
Answer:
50+0.4*50
Step-by-step explanation:
Because it has 140% of the RDA and the RDA is 50, that means it has 50 and 40% or 0.4 of 50. So the answer is 70 mg.
Three yrs hence, a men will be three time his brother age and the sum of present age is 18 find their present age
Answer:
Step-by-step explanation:
Let the age of a man = x
Age of his brother = y
Three yrs hence, a man will be three time his brother age
This is written as:
x + 3 = 3(y + 3)
x + 3 = 3y + 9 .... Equation 1
The sum of present age is 18
= x + y = 18
x = 18 - y
We substitute 18 - y for x in Equation 1
find their present age
18 - y + 3 = 3y + 9
Collect like terms
21 - 9 = 3y + y
12 = 4y
y = 12/4
y = 3 years
x = 18 - y
x = 18 - 3
x = 15 years

What is the length of AC?
Answer:
10 + 20 = 30
Step-by-step explanation:
If you subtract 5 from 25 you get 20 which is the length distance from b to c. Let's do the same to 15, 15 - 5 = 10. So now let's add our given lengths: 10 + 20 = 30.
The perimeter of a rectangular parking lot is 286 m.
If the width of the parking lot is 56 m, what is its length?
Answer:
87 metres
Step-by-step explanation:
The perimeter of the parking lot is 286 metres, while it is 56m in width.
The formula for the perimeter of a rectangle is:
[tex]P = 2(l+w)\\P = 2l + 2w[/tex]
with l and w as the the length and width, respectively.
The problem has two givens, perimeter and width.
[tex]286 = 2l + 2w\\286 = 2l + 2(56)\\286 - 112 = 2l\\174 = 2l\\\frac{174}{2} = l\\l=87[/tex]
The length of the lot is 87 meters.
Describe and correct the error a student made when writing the quadratic function f(x)=2(x+3)^2-4 in standard form
The student did not
A. Compute 9-4 correctly
B. Compute (x+3)^2 correctly
C. Distribute 2 to all necessary terms
The function in standard form is f(x)=
Answer:
y = 2x^2 + 12x + 14
Step-by-step explanation:
Write this equation in standard form. Start by performing the exponentiation:
y = 2(x^2 + 6x + 9) - 4
Perform the indicated multiplication:
y = 2x^2 + 12x + 18 - 4, or
y = 2x^2 + 12x + 14: This is the quadratic function in standard form.
The value of the quadratic function in standard form is,
⇒ f (x) = 2x² + 12x + 14
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The function is,
⇒ f (x) = 2 (x + 3)² - 4
Now, We get;
The value of the quadratic function in standard form is,
⇒ f (x) = 2 (x + 3)² - 4
⇒ f (x) = 2 (x² + 9 + 6x) - 4
⇒ f (x) = 2x² + 18 + 12x - 4
⇒ f (x) = 2x² + 12x + 14
Thus, The value of the quadratic function in standard form is,
⇒ f (x) = 2x² + 12x + 14

Write the point-slope form of the equation of the line through the given points.
(4,-4), slope = -2
Oy+4 = –2(x – 4)
Oy - 4= 2(x + 4)
Oy+2 = 4(x - 4)
Oy - 2 = 4(x +4)
Terms
Answer:
first option
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = - 2 and (a, b ) = (4, - 4 ) , then
y - (- 4) = - 2(x - 4) , that is
y + 4 = - 2(x - 4)
