The heights of young American women, in inches, are approximately Normally distributed with mean μ and standard deviation σ = 2.4. If I want to construct a 99% confidence interval with a margin of error of no more than ± 1 inch, what is the smallest sample I can select?
The smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.
The margin of error (E) for a confidence interval is described as:
E = z × (σ / √n)
where:
E is the desired margin of error
z is the z-score corresponding to the desired confidence level (in this case, 99% confidence level)
σ is the population standard deviation
n is the sample size
In this case, the margin of error is no more than ±1 inch, so E = 1 inch.
Now, determine the z-score corresponding to a 99% confidence level using a standard normal distribution table or statistical software.
For a 99% confidence level, the z-score is approximately 2.576.
Plugging in the known values into the margin of error formula,
1 = 2.576 × (2.4 / √n)
To solve for n, rearrange the formula as follows:
√n = (2.576 × 2.4) / 1
√n = 6.1824
n = (6.1824)²
n ≈ 38.16
Therefore, the smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

A rectangular yard measuring 37' x 43' is bordered and surrounded by fence. Inside, a walk that is 2 foot wide goes all the way along the fence. Find the area of this walk.
Answer:
[tex]A=160ft^2[/tex]
Step-by-step explanation:
Length of yard [tex]l=37ft[/tex]
Width of yard [tex]w=43ft[/tex]
Walk [tex]l_w=2ft[/tex]
Generally the perameter of the fence P is mathematically given by
[tex]P=l+w[/tex]
[tex]P=37+43[/tex]
[tex]P=80[/tex]
Generally the equation for area of walk is mathematically given by
[tex]A=P*l_w[/tex]
[tex]A=80*2[/tex]
[tex]A=160 ft^2[/tex]
Therefore area of walk is
[tex]A=160ft^2[/tex]

Jim had 3 cups. He filled each cup 2 and 1/2 full of water. How much water is there altogether
hi this is due in 10 minutes so im gonna dump some question you you :p
1. A cupcake recipe calls for 4 cups of flour and 2 cups of sugar. Angelica only has 3 cups of flour. How much sugar would she need to keep the ratio equivalent if she uses all the flour she has? Show your mathematical thinking below and then chose the amount of sugar she needs to use
2. Your parents are interested in the amount of sugar in two drinks. The apple juice has 216 grams of sugar for every 8 servings. The soda has 234 grams of sugar for every 9 servings.
3. The Workman's family car travels 165 miles in three hours. Their cousins' family car travels 150 miles in two hours. If the family reunion is 900 miles away for both families, and assuming both families travel at their same rate for the entire trip, who will arrive first? First you will need to find the speed at which each car travels. This is the unit rate - miles per hour
thats all, i dont have much points but here is what i have left :,)
Answer:
1. You need 1.5 cups of sugar because the ratio is that the flour is always double the sugar and 3/2 is 1.5
2. 27 grams of sugar per serving for apple juice and 26 grams of sugar per serving for soda
3. The workman's car goes 55 miles per hour and their cousins goes 75 miles per hour

Answer:
C
Step-by-step explanation:
lol didn't i just answer one of your questions, also give me brainliest pls :)
First, the function was multiplied by 3, which is a vertical dialation by a factor of 3. Then, we subtracted 2 from the function, which is a vertical shift down two units. Therefore, the answer is C
The transformations are applied to the graph of the function should be option c. a vertical dilation by a factor of 3 and a vertical shift down 2 units
What transformation should be applied:Since
First, the function should be multiplied by 3, that represent vertical dilation by a factor of 3. After this, we subtracted 2 from the function, i.e. is a vertical shift down two units.
Therefore, the answer is C a vertical dilation by a factor of 3 and a vertical shift down 2 units.

Answer:
................................
Answer:
23
Solving steps
We know x= -10-15y, so we can subtract it to the equation above
x = -10-15y
2x+5y=35
2(-10-15y) + 5y = 35
(Refer to the 1st image to solve for y)
Y = -11/5
We now know y= -11/5, so we can subtract it to the equation for x.
Y = -11/5
x = -10-15y
x = -10-15(-11/5)
(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)
x = 33 - 10
x = 23

D. F’(-6,0)
Answer:

Step-by-step explanation:
i just had this question
A translation is a transformation that moves every point in a figure in the same direction by the same amount. The coordinates of F' is (-6, 0).
What is translation?A translation is a transformation that moves every point in a figure in the same direction by the same amount. It is also a sort of transformation in which each point in a figure is moved the same distance in the same direction resulting in the same figure again.
Since the transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.
Given a parallelogram EFGH that is been translated 6 units to the left and 3 units up.
Since the coordinates of F' is (0, -3). Therefore, the coordinates of F’ can be written as,
F = (0, -3)
F' = (0 - 6, -3 + 3)
F' = (-6, 0)
Hence, the coordinates of F' is (-6, 0).
