The location of the coin next to the convex side of a thin spherical glass shell is 3.68 cm.
According to the question,
Radius of curvature : 19 cm
Size of image formed : 1.5cm
Distance of coin from glass shell : 6.5cm
The position of the coin placed next to the convex side of a thin spherical glass shell is calculated as follows;
1/d = 1/f - 1/d'
where;
d' is the position of the coin's image
d position of the coin
f is focal length
Focal length = r/2 =19/ 2 = 9.5 cm
=> 1/d = 1/9.5 - (-1/6.5)
=> 1/d = 1/9.5 + 1/6.5
=> 1/d = 0.1052 + 0.1538
=> 1/d = 0.259
=>d = 1/0.259
d = 3.86 cm
Thus, the position of the coin placed next to the convex side of a thin spherical glass shell is 3.86 cm.

stocks a and b each have an expected return of 12%, a beta of 1.2, and a standard deviation of 25%. the returns on the two stocks have a correlation of 0.6. portfolio p has 50% in stock a and 50% in stock b. which of the following statements is correct?
The correct answer is The standard deviation for Portfolio P is less than 25
This response is accurate because a portfolio made up of two stocks with a correlation of less than one will always have a standard deviation that is lower than the standard deviation of the stocks added in accordance with their weight in the portfolio. For example, in this scenario, both stocks have a weight of 50% and a standard deviation of 25%, so their sum will be.
The portfolio standard deviation will be smaller than 25% since (0.5*25%) + (0.5*25%) = 25%.
Therefore, the standard deviation for Portfolio P is less than 25

Step-by-step explanation:
1. Rearrange Terms
-3(3 + 6b) = 36 - 3b
-3(6b + 3) = 36 - 3b
2. Distribute
-3(6b + 3) = 36 - 3b
-18b - 9 = 36 - 3b
3. Rearrange Terms
-18b - 9 = 36 - 3b
-18b - 9 = -3b + 36
4. Add 9 to both sides
-18b - 9 = -3b + 36
-18b - 9 + 9 = -3b + 36 + 9

A plot of land for sale has a width of x ft. , and a length that is 8ft less than its width. A farmer will only purchase the land if it measures 240 square feet. What value of x will cause the farmer to purchase the land?.
If width i.e. x is 20 ft then the farmer will purchase the land.
Given,
width of land = x ft
length of land = ( x - 8 ) ft
Area of land =240 square feet
To determine x use formula,
Area of land =length * width
[tex]240=(x-8)*x\\\\240=x^2-8x\\\\x^2-8x-240=0\\\\x^2+12x-20x-240=0\\\\x(x+12)-20(x+12)=0\\\\(x+12)(x-20)=0\\\\x=-12\ or\ 20[/tex]
x cannot be negative.
x=20 ft
Thus, if width i.e. x is 20 ft then the farmer will purchase the land.

Of people who died in the United States in recent years, 86% were white, 12% were black, and 2% were Asian. (This ignores a small number of deaths among other races.) Diabetes caused 2.8% of deaths among white people, 4.4% among black people, and 3.5% among Asians. What is the probability that a randomly chosen death is a white person who died of diabetes? (Round your answer to three decimal places.)
The probability that a randomly chosen death is a white person who died of diabetes is 0.024 determined using the law of total probability.
The law of total probability is a fundamental rule that connects marginal probabilities to conditional probabilities and expresses the total probability of an outcome via several distinct events. The rule states that if the probability of an event is unknown, it can be calculated using the known probabilities of several distinct events. It is given by P(A ∩ B) = P(A|B)P(B)
In order to determine the probability of an event (D) with not enough information to calculate it directly, a related event, say W can be taken and use that to calculate the probability for D.
Let the events that a person from a certain race die be denoted as:
P(W) = 0.86; P(B) = 0.12; P(A) = 0.02
Let the events that a person from a certain race dies of diabetes be denoted as:
P(D/W) = 0.0.028; P(D/B) = 0.044; P(D/A) = 0.035
Probability that a randomly chosen death is a white person who died of diabetes
P(W) x P (D/W) = 0.86 x 0.028 = 0.02408 ≈ 0.024

what is the difference between the critical value of z and the observed value of z (test statistic)?
The critical value of z separates the rejection region from the nonrejection region while observed value of z is the value calculated for a sample statistic such as x.
A critical value of z is used when the sampling distribution is normal, or close to normal. The critical value of z refers to the point that cuts off area under graph for the standard normal distribution separating the rejection and nonrejection region of the data. The Critical value of z can indicate what probability any particular variable will have. These values are typically obtained from a table such as the standard normal distribution table. The observed value of z is a value determined for a sample statistic x. It is a test statistic for Z-tests that measures the difference between an observed statistic and its hypothesized population parameter in units of the standard deviation.

The speed of a runner increased steadily during the first three seconds of a race. Her speed at half-second intervals is given in the table. Find lower and upper estimates for the distance that she traveled during these three seconds. t (s) 0 0.5 1.0 1.5 2.0 2.5 3.0 v (t/s)|이 6.2 | 10.8 | 14.9 | 18.1 19.4 20.2 Step 1 We will use either Ls or Rs for the upper and lower estimates. Since the runner's speed is an increasing function, then will give the lower estimate, andR will give the upper estimate. ˇ Step 2 The sub-interval widths At for this situation are At- L--JX
The speed of the runner calculated by the properties of average speed is given by 33.45 feet and the upper limit is 43.45 feet in the last 3 seconds.
The first three seconds of a race saw a runner's speed rapidly grow.
The time is therefore 3 seconds.
The table provides her speed at half-second intervals.
We are aware,
Distance x Time = Speed
Similarly
Distance equals speed x time.
Δt equals 0.5 seconds
Then, the minimum distance travelled overall is equal to
0.5(0 + 6.7 + 9.2 + 14.1 + 17.5 + 19.4).
Terms are multiplied and added.
= 0.5 × 66.9
= 33.45 feet
The maximum distance travelled is equal to
0.5 (6.7 + 9.2 + 14.1 + 17.5 + 19.4 + 20)
= 0.5 × 86.9
= 43.45 feet
As a result, her maximum distance in three seconds is 43.45 feet, and her maximum distance in three seconds is 33.45 feet.

Using law of sine and triangle rule, the value of n will be; 443 inches
What is Sine Rule?The law of sines establishes the relationship between the sides and angles of an oblique triangle(non-right triangle). Law of sines and law of cosines in trigonometry are important rules used for "solving a triangle".
We can apply the sine rule to find the missing angle or side of any triangle using the requisite known data.
The formula is given as;
a / sin A = b / sin B = c / sin C
In this triangle NOP, we can find the value of angle P then;
∠N + ∠O + ∠P = 180
57 + 55 + ∠P = 180 :
since Sum of angles in a triangle is equal 180 degrees
∠P= 180 - 112
∠P = 68
Using law of sine;
p / sin P = n / sin N
490 / sin68 = n / sin57

Avery's songs were played on
commercials and
movies.
The number of movies on which Avery's songs were played is 2 times
How to determine the number of movies on which Avery's songs were played.From the question, we have the following parameters that can be used in our computation:
Songs played in commercial = $40
Songs played in movie = $140
Total earnings = $480
Number of times played on commercial = 7
The above parameters when represented as an equation is
Total earnings = Songs played in commercial * Number of times played on commercial + Songs played in movie * Number of times played in a movie
Substitute the known values in the above equation, so, we have the following representation
40 * 7 + 140 * Number of times played in a movie = 480
Evaluate the products
280 + 140 * Number of times played in a movie = 480
So, we have
Number of times played in a movie = 200/140
