the school store has1200 pendls in stock and sells and sells an average of 25 pencils per day the manager reorders when the number of pencils in stock in 650

Answer:

9.375 days

Step-by-step explanation:

Let d be the number of days the do 1 work(job). The speed A can do the job is (1/3)/(5)=1/3 × 1/5=1/15. The speed B can do the job is (2/5)/(10)=2/5 × 1/10=2/50=1/25. (These speeds have units work per 1 day)

So the amount of work done in d days for A is 1/15×d=d/15 and that same amount of days B does 1/25×d=d/25 work.

We are trying to figure out when they ddo 1 work together.

We need to solve

d/15+d/25=1

Multiply both sides by 75=least common multiple of 15 and 25.

75d/15+75d/25=75

Reducing:

5d+3d=75

Combine like terms:

8d=75

Divide both sides by 8:

d=75/8

d=9.375

The total number of seeds that Josiah would plant would be = nR×S

To determine the total number of seeds that Josiah will plant will be to add the seeds in the total number of rooms he planted.

Let each row be represented as = nR

Where n represents the number of rows planted by him.

Let the seed be represented as = S

The total number of seeds he planted = nR×S

Therefore, the total number of seeds that was planted Josiah would be = nR×S.

Bijective (I believe)

Step-by-step explanation:

A bijective function, f: X → Y, where set X is {1, 2, 3, 4} and set Y is {A, B, C, D}. For example, f(1) = D.

The slope of the tangent line to the curve at P(0.25, 20).

The point P(1/4,20) lies on the curve y = 5/x.

If Q is the point (x,5/x) and we have to find the slope of the secant line PQ for various values of x.

We have the following values of x:If x = 0.35, the slope of PQ is:

(5/0.35 - 20) / (0.35 - 0.25)

= (14.29 - 20) / 0.1= -57.1

If x = 0.26, the slope of PQ is: (5/0.26 - 20) / (0.26 - 0.25)= (19.23 - 20) / 0.01= -77.7

If x = 0.15, the slope of PQ is: (5/0.15 - 20) / (0.15 - 0.25)= (33.33 - 20) / -0.1= -133.3

If x = 0.24, the slope of PQ is: (5/0.24 - 20) / (0.24 - 0.25)= (20.83 - 20) / -0.01= -83.3

Based on the above results, guess the slope of the tangent line to the curve at P(0.25, 20).

We can observe that as we take x closer to 0.25, the slope of the secant line PQ is decreasing, and from the above calculations, we can guess that the slope of the tangent line to the curve at P(0.25, 20) is approximately -80.

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Using the arrangements formula, it is found that there is a 0.0178 = 1.78% probability that all the girls are ahead of all the boys.

The number of possible arrangements of the n elements is the factorial of n, that is:

\(A_{n} = n!\)

The total number of outcomes is the arrangement of 8 elements, hence:

T = 8! = 40320

The desired number of outcomes is all-girls(5!), then all-boys(3!), hence:

D = 5! × 3! =120× 6=720

Hence, the probability is:

p = D/T =720/40320 = 0.0178

There is a 0.0178 = 1.78% probability that all the girls are ahead of all the boys.

The net price for 20 boxes of computer paper with a unit price of ​$12.65 and a single trade discount rate of 40​% is ​$151.80.

1. First, determine the discount amount by multiplying the unit price by the discount rate.az
$12.65 (unit price) x 0.40 (40% discount rate) = $5.06 (discount amount)
The unit price is ​$12.65, so the total price for 20 boxes would be:
$12.65 x 20 = $253

2. Next, calculate the net price for one box of computer paper by subtracting the discount amount from the unit price:
Now, we need to apply the single trade discount rate of 40%. To do this, we can use the formula:

Discount = total price x discount rate

Discount = $253 x 0.40

Discount: = $101.20
$12.65 (unit price) - $5.06 (discount amount) = $7.59 (net price per box)

3. Finally, find the net price for 20 boxes of computer paper by multiplying the net price per box by the number of boxes:
The discount is $101.20, so the net price would be:

Net price = total price minus discount

Net price = $253 - $101.20

Net price $151.80
$7.59 (net price per box) x 20 (boxes) = $151.80 (net price for 20 boxes)

So, the net price for 20 boxes of computer paper with a 40% discount is $151.80.

From the 64 values in the table on the left, count how many fall within the given ranges under the "classes" column in the table on the right. The "frequency" is the number of values in the data that belong to a given "class".

For example, "< -16.0" means "values below -16.0". Only one number satisfies this: -16.2 (first row, third column). So the frequency for this class is just 1.

Then for the range "-15.9 - 13.0", which probably means "numbers between 15.9 and -13.0, inclusive", the frequency is 0 because every number in the table is larger than the ones in this range.

And so on.

The correct answer is D. 8 feet. is the least possible whole number measure for the third side.

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Therefore, to find the least possible whole number measure for the third side, we need to determine the smallest possible sum of the two given sides.

Given side lengths:

Side 1 = 3.1 feet

Side 2 = 4.6 feet

The sum of these two sides is:

3.1 + 4.6 = 7.7 feet

To find the least possible whole number measure for the third side, we need to find a whole number that is greater than 7.7 feet.

Among the given options:

A. 1.6 feet

B. 2 feet

C. 7.5 feet

D. 8 feet

The only option that meets the criteria is option D, 8 feet. Since 8 is the smallest whole number greater than 7.7, it is the least possible whole number measure for the third side.

Therefore, the correct answer is D. 8 feet.

The value of x for which (f - g)(x) = 0 is x = 12.

To find the value of x for which (f - g)(x) = 0, we need to subtract g(x) from f(x) and set the resulting expression equal to zero. Let's perform the subtraction:

(f - g)(x) = f(x) - g(x)

= (16x - 30) - (14x - 6)

= 16x - 30 - 14x + 6

= 2x - 24

Now, we can set the expression equal to zero and solve for x:

2x - 24 = 0

Adding 24 to both sides:

2x = 24

Dividing both sides by 2:

x = 12

Therefore, the value of x for which (f - g)(x) = 0 is x = 12.

each side of a line equals 180 degrees, so subtracting 180-121=c gives you 59 degrees.

a and c are congruent angles so they are also equal to each other

a) The mean of the sampling distribution would be 0.39. This is because the true proportion of smartphone users is given as 39%, and when we draw a random sample of investors, the sample proportion of smartphone users would be expected to be close to the true proportion.

b) The mean cannot be determined. This statement is incorrect. Based on the information given, the mean of the sampling distribution can be determined and it would be 0.39.

c) If the sample size were increased to 400, the mean would still be the same.

The shape and symmetry characteristics of the sampling distribution would remain approximately the same. Increasing the sample size helps to improve the accuracy and precision of estimating the proportion, but it does not affect the mean. The mean would still be 0.39, reflecting the true proportion of smartphone users.

Answer:

The slope of a linear model can be calculated using the formula:

m = Δy / Δx

where:

Δy = change in y (the dependent variable, in this case, total cost)

Δx = change in x (the independent variable, in this case, number of candy bars)

This is essentially the "rise over run" concept from geometry, applied to data points on a graph.

In this case, we can take two points from the table (for instance, the first and last) and calculate the slope.

Let's take the first point (3 candy bars, $6.65) and the last point (25 candy bars, $48.45).

Δy = $48.45 - $6.65 = $41.8

Δx = 25 - 3 = 22

So the slope m would be:

m = Δy / Δx = $41.8 / 22 = $1.9 per candy bar

This suggests that the cost of each candy bar is $1.9 according to this linear model.

Please note that this assumes the relationship between the number of candy bars and the total cost is perfectly linear, which might not be the case in reality.
