For the given number of shares 1,239 and cost price per share is $19.36 and selling price per share $27.93 then gain percent is equal to
44.27%( nearest hundredth place).
As given in the question,
Total number of shares = 1,239 shares
Cost price per share = $19.36
Cost price of 1,239 shares = 1,239 × 19.36
= $ 23987.04
Selling price per share = $27.93
Selling price of 1,239 shares = 1,239 × 27.93
= $ 34605.27
Selling price > Cost price
Gain amount = 34605.27 - 23987.04
= $10618.23
Gain percent = [(10618.23) /(23987.04) ] × 100
= 44.2665..
= 44.27%
Therefore, for the given number of shares 1,239 and cost price per share is $19.36 and selling price per share $27.93 then gain percent is equal to 44.27%( nearest hundredth place).

Students in the HC States Advisory are covering one of their homeroom walls with wallpaper. The wall is rectangular and has a perimeter of 408 ⅜ inches. The students are using square stickers with a side length of 2 ⅜ inches to cover the wall. If they need exactly 18 stickers to completely cover the width of the wall, how many whole stickers can they fit across the length of the wall?
Answer:
cm2 to inch2 conversion. Conversion square centimeters to square inches, cm2 to inch2. The conversion factor is 0.15500031000062; so 1 square centimeter ...
Step-by-step explanation:
A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
The perimeter of a rectangle.
= 2 ( length + width)
The number of 2(3/8) inches tickets to fit into the length of the wall is
154 tickets.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
The perimeter of a rectangle.
= 2 ( length + width)
The wall is rectangular and has a perimeter of 408 ⅜ inches.
This means,
408 (3/8) = 2 (length + width)
3267/8 = 2 (length + width) _____(1)
Now,
The total width of the wall.
= 2 width
Now,
Length of the square stickers = 2 (3/8) inches = 19/8 inches
The number of stickers needed to cover the width of the wall = 18
2 width = 18 x 19/8 inches.
2width = 18 x 19/8
width = 171/8 inches
Now,
From (1) we get,
3267/8 = 2 (length + width)
3267/8 = 2 (length + 171/8)
3267/8 - 342/8 = 2 length
2925/(8 x 2) = length
2length = 2925/(8 x 2)
2length = 2925/8
The number of stickers to cover the total length.
= 2925/8 ÷19/8
= (2925 x 8)/ (19 x 8)
= 154
Thus,
The number of 2(3/8) inches tickets to fit into the length of the wall is
154 tickets.

Two friends, Karen and Jodi, work different shifts for the same ambulance service. They wonder if the different shifts average different numbers of calls. Looking at past records, Karen determines from a random sample of 37 shifts that she had a mean of 4.5 calls per shift. She knows that the population standard deviation for her shift is 1.1 calls. Jodi calculates from a random sample of 32 shifts that her mean was 5.3 calls per shift. She knows that the population standard deviation for her shift is 1.5 calls. Test the claim that there is a difference between the mean numbers of calls for the two shifts at the 0.05 level of significance. Let Karen's shifts be Population 1 and let Jodi's shifts be Population 2. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places
The Test value for difference between the mean numbers of calls for the two shifts at the 0.05 level of significance is 31.94
According to the question,

Sample size : n₁ = 37
Sample mean = 4.5
Sample standard deviation : s₁ = 1.1
Jodi's data ,
Sample size : n₂ = 32
Sample mean = 5.3

Answer:
$83.44=======================
GivenFunction c(d):
c(d) = 0.24d + 34Find the value of c(d) when d = 206:
c(206) = 0.24*206 + 34 = 49.44 + 34 = 83.44Answer:
Cost = $83.44
Step-by-step explanation:
The given equation is,
→ c(d) = 0.24d + 34
Now the required cost will be,
→ c(d) = 0.24d + 34
→ c(206) = 0.24(206) + 34
→ c(206) = 49.44 + 34
→ c(206) = $83.44
Hence, the cost is $83.44.

Step-by-step explanation:
Answer:
Minimum Unit Cost = $14,362
Step-by-step explanation:
The standard form of a quadratic is given by:
ax^2 + bx + c
So for our function, we can say,
a = 0.6
b = -108
c = 19,222
We can find the vertex (x-coordinate where minimum value occurs) by the formula -b/2a
So,

how do you subtract mixed fractions?
Answer: Making them into improper fractions will really help you with subtracting mixed fractions! For example 2[tex]\frac{1}{5} \\[/tex] - 1[tex]\frac{1}{4}[/tex].
Making them into improper fractions will turn the expression into [tex]\frac{11}{5}[/tex] - [tex]\frac{5}{4}[/tex].
Turn the denominators into the greatest common multiple, so the greatest common multiple of 5 and 4 is 20. Meaning you multiply [tex]\frac{11}{5}[/tex] by 4 and [tex]\frac{5}{4}[/tex] by 5.
You now have [tex]\frac{44}{20} -\frac{25}{20}[/tex], which is much easier to work with. Simply subtract the numerators, and you should get [tex]\frac{19}{20}[/tex].

The factorization of given expression would be,

Mathew drives m miles in x hours. How many hours would he save if he drove the same distance at k miles per hour
The time saved will be: x - m/k This is a simple exercise in manipulating symbols. Let's take a look at the problem and break it down. "Stanley drives m miles in x hours" This statement immediately gives us 2 variables; "m" to represent how many miles the trip is and "x" for the number of hours it took Stanley to drive that far. Now let's look at the next statement. "How many hours would he save if he drove the same distance at k miles per hour?" This statement gives us another variable "k" for a new speed and gives us the question to answer. How many hours would Stanley save if he made the trip at a different speed. Since we're interested in hours saved, we need 2 different time values. They are 1. How much time did Stanley originally take? 2. How much time will the new speed make Stanley take? Looking at m, x, and k. We can immediately see that x is the original time that Stanley took. So we have that value. But we don't have any value for how long will it take at a new speed. But can we calculate it? And the answer to that is YES. The time it will take is the distance divided by the new speed. And that would be m/k. And since we're looking for savings, we just need to subtract the two time values. So our equation becomes x - m/k where x = original time taken m = distance of trip k = new speed to drive at.

A model is probably overfitting the training data if it performs well on the training data but poorly on new examples (or we got extremely lucky on the training data). Obtaining more data, simplifying the model (choosing a simpler technique, reducing the amount of parameters or features utilized, or regularizing the model), or lowering the noise in the training data are all potential remedies for overfitting.
