3. The annual per capita consumption of fresh bananas in the United States can be approximated by a normal distribution, with a mean of 10.4 pounds and a standard deviation of 3 pounds. What is the largest annual per capita consumption of bananas that can be in the bottom 5 % of consumption
Answer:
The largest annual per capita consumption of bananas in the bottom 5% of consumption is 5.465 lb
Step-by-step explanation:
Given
μ = Mean = 10.4 lb
σ = Standard deviation = 3 lb
Using a confidence level of 90%,
We'll need to first determine the z value that correspond with bottom 5% of consumption of banana
α = 5%
α = 0.05
So,
zα = z(0.05)
z(0.05) = -1.645 ----- From z table
Let x represent the largest annual per capita consumption of bananas
The relationship between x and z is
x = μ + zσ
By substitution;
x = 10.4 + (-1.645) * 3
x = 10.4 - 4.935
x = 5.465
Hence, the largest annual per capita consumption of bananas in the bottom 5% of consumption is 5.465 lb

Huma hubna and seema recieved a total of rs 2016 as monthly allowance from their mother such that seema gets 1/2 og what huma gets and hubna gets 1 2/3 times seemas share how much do the three sisters get individually
Answer:
huma's share= Rs.864
Seema's share= Rs.432
Hubna's share= Rs.720
Step-by-step explanation:
Considering 'x' as the share of huma
Therefore , Seema's share will be x/2
And Hubna's share will be 5/3 * x/2 => 5x/6
Total money given in the problem is Rs.2016
In order to find the share of individual, we first have to determine 'x' variable by taking the sum of all shares.
x+x/2+5x/6=Rs.2016
(6x+3x+5x)/6=2016
14x/6=2016
x=2016 * 6/14
x=864.
Therefore,huma's share 'x' will be Rs.864
Seema's share will be = x/2 = Rs.432
And Hubna's share will be = 5x/6= Rs.720
Use the formula to find the lateral area and surface area of prism
Answer:
The answer to your question is 2046 in²
Step-by-step explanation:
Data
length = 30 in
base = 24 in
hypotenuse = 25 in
Process
1.- Calculate the height of the triangle using the Pythagorean theorem
c² = a² + b²
-Solve for b
b² = c² - a²
-Substitution
b² = 25² - 24²
-Simplification
b² = 625 - 576
-Result
b² = 49
b = 7 in
2.- Calculate the area of the base
Area = base x height
Area = 24 x 7 x 2
= 336 in²
3.- Calculate the lateral area
Area = 30 x 25 x2
= 1500 in²
4.- Calculate the last area
Area = 30 x 7
= 210
5.- Final area
Total area = 210 + 1500 + 336
= 2046 in²

Can repeating decimals be written as a fraction?
Answer:
yea i think yea yes yes yes yes
Final answer:
Yes, repeating decimals can be expressed as fractions using a simple algebraic equation.
Explanation:
Yes, repeating decimals can be expressed as fractions. To represent a repeating decimal as a fraction, you can use a simple algebraic equation. Let's take an example:
Consider the repeating decimal 0.3333... Now, let x be the number we want to express as a fraction. We can multiply both sides of the equation by 10 in order to move the decimal point to the right and eliminate the repeating part:
x = 0.3333...
10x = 3.3333...
Now, we subtract the two equations to eliminate the repeating part:
10x - x = 3.3333... - 0.3333...
Combining like terms:
9x = 3
Finally, dividing by 9 gives us the fraction representation of the repeating decimal:
x = 3/9 = 1/3
You pick a card at random .without putting the first card back you pick a second card at random what is the probability of picking a 4 and then picking 4

The probability of drawing a 4 and then another 4 in sequence without replacement from a 52-card deck is 1/221, calculated by multiplying the probabilities of drawing a four on the first and second draws, 1/13 and 1/17, respective
Explanation:
The question involves calculating the probability of drawing two specific cards in sequence without replacement from a standard deck of 52 cards. The condition provided is drawing a 4 first and then drawing another 4 without putting the first card back. To solve this, consider the probability of each event happening.
For the first draw, there are 4 fours in a deck of 52 cards, so the probability of drawing a four (P(A)) is 4/52 or 1/13.
After drawing one four and not returning it, there are now 51 cards left and only 3 fours left. Therefore, the probability of drawing a four as the second card (P(B) given A) is 3/51 or 1/17.
To find the total probability of both events happening in sequence, multiply the probabilities of the individual events: 1/13 * 1/17.
Thus, the probability of drawing a 4 and then another 4 in sequence without replacement is 1/221.

A projectile is fired straight upward with an initial velocity of 400 feet per second. The height of the projectile, h(t), if represented by the function h(t)=-16t^2+400t, where t is the time in seconds. How long does it take the projectile to reach the maximum height?
Taking into account the definition of maximum, minimum and vertex of a quadratic function, it takes 12.5 seconds for the projectile to reach maximum height.
A quadratic function is defined in the form:
y= f (x) = ax² + bx + c
Every quadratic function has a maximum or a minimum, which is the vertex of the parabola. If the parabola has an upward concavity, the vertex corresponds to a minimum of the function; whereas if the parabola has concavity downwards, the vertex will be a maximum.
That is, if the coefficient a is positive the parabola is concave and the vertex will be a minimum of the function, while if a is negative the parabola will be convex and the vertex is a maximum.
The maximum or minimum is reached in [tex]xv=\frac{-b}{2a}[/tex]
The maximum or minimum value of y is obtained by evaluating the function at xv, this is, f (xv).
In this case, the function is:
h(t)= -16t² + 400t
where t is the time in seconds
Being a = -16 and b = 400, the value of a is negative, so the vertex will be the maximum.
You want to know the time it takes for the projectile to reach the maximum height, that is, the maximum in t. That is, you must calculate t using the expression: [tex]t=\frac{-b}{2a}[/tex]
So: [tex]t=\frac{-400}{2x(-16)}[/tex]
Solving:
[tex]t=\frac{-400}{-32}[/tex]
t= 12.5 seconds
It takes 12.5 seconds for the projectile to reach maximum height.

1. What is the measure of angle A'B'C?
a. 20°
b. 40°
C. 60°
d. 80°
Answer:
B
Step-by-step explanation:
Compare triangle ABC with triangle A'B'C. Let's try to prove that they're similar.
BC = 6 + 3 = 9 units
B'C = 6 units
BC/B'C' = 9/6 = 3/2 = 1.5
AC = 2 + 4 = 6 units
A'C = 4 units
AC/A'C = 6/4 = 3/2 = 1.5
These two pairs of corresponding sides have the same ratio, so that's promising.
Also notice that angle BCA = angle B'CA'. So, by SAS Similarity Theorem, we know that triangles ABC and A'B'C are similar.
By definition, similar triangles have the same corresponding angles.
Angle ABC corresponds to angle A'B'C, so they're equal. Since angle ABC = 40 degrees, then angle A'B'C = 40 degrees, as well.
Hope this helps!
Without proper context or a diagram, it's impossible to definitively state the measure of angle A'B'C. However, as an example, if angle A'B'C is in an equilateral triangle, it would be 60 degrees.
Explanation:The question appears to be asking about the measure of an angle, designated as A'B'C. However, without proper context or a diagram to reference, it's impossible to definitively state what the measure of angle A'B'C is. It can be any value depending on the context. But, if A'B'C is a part of a triangle or a particular geometric shape with known properties, we can solve it based on the information given related to that specific shape.
For example, in an equilateral triangle, each angle measures 60°. So, if A'B'C is an angle in an equilateral triangle, it would most likely be 60°. Yet, without sufficient context, this is simply a hypothetical situation.

Suppose ACT Reading scores are normally distributed with a mean of 21 and a standard deviation of 6.1. A university plans to award scholarships to students whose scores are in the top 9%. What is the minimum score required for the scholarship?
Answer: the minimum score required for the scholarship is 29.24
Step-by-step explanation:
Since the scores are normally distributed, it follows the central limit theorem. The formula for determining the z score is
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
Since the university plans to award scholarships to students whose scores are in the top 9%, the scores that would be qualified are scores which are at least 91%(100 - 9 = 91).
Looking at the normal distribution table, the z score corresponding to the probability value of 0.91(91/100) is 1.35
From the information given,
µ = 21
σ = 6.1
Therefore,
1.35 = (x - 21)/6.1
6.1 × 1.35 = x - 21
8.235 = x - 21
x = 8.235 + 21 = 29.24
The minimum ACT Reading score required to be in the top 9% for a university scholarship is approximately 29.2, determined by using a z-score of 1.34, the mean score of 21, and the standard deviation of 6.1.
To determine the minimum ACT Reading score required to be in the top 9% of students, and hence eligible for a scholarship at a university, we utilize the concept of z-scores in a normal distribution. A z-score indicates how many standard deviations an element is from the mean.
First, we need to find the z-score that corresponds to the top 9% of the distribution. Standard z-score tables or calculators will show that the z-score for the top 9% is approximately 1.34. This z-score means the score is 1.34 standard deviations above the mean. Next, we apply the z-score formula:
Z = (X - μ) / σ
Where:
Z is the z-score (1.34 in this case),
X is the ACT score we want to find,
μ is the mean (21 for ACT Reading),
σ is the standard deviation (6.1 for ACT Reading).
We can rearrange the formula to solve for X (the ACT score):
X = Z * σ + μ
Substituting the values we have:
X = 1.34 * 6.1 + 21
X ≈ 29.214
The minimum ACT Reading score required for the scholarship is therefore approximately 29.2 when rounded to the nearest tenth.

If you have a box of candy that is 8 inches long 5 inches wide and 2 inches tall how much space do you have for candy?
Answer:
you would have 80 units of space
Step-by-step explanation:
to find out how much volume there is you have to multiply the base x the width x the height so that would be 8x5x2 and 8x5 is 40 and 40x2 is 80
The box has a volume of 80 cubic inches, determined by multiplying its dimensions: length (8 inches), width (5 inches), and height (2 inches).
To determine the space available for candy in the given box, we need to calculate the volume of the box. The volume of a rectangular box can be found by multiplying its length, width, and height. Here, the box measures 8 inches in length, 5 inches in width, and 2 inches in height.
To find the volume, use the formula:
Volume = Length × Width × Height
In this case, the volume is:
Volume = 8 inches × 5 inches × 2 inches = 80 cubic inches
Therefore, the box has 80 cubic inches of space available for candy.
