Answer:

The cost of one share of the stock on Friday is $41.45

Step-by-step explanation:

The initial cost of one share of the stock on Monday is $41.45.

On Tuesday, the cost goes up by $0.58, so the cost becomes:

$41.45 + $0.58 = $42.03

On Wednesday, the cost goes down by $0.26, so the cost becomes:

$42.03 - $0.26 = $41.77

On Thursday, the cost also goes down by $0.26, so the cost becomes:

$41.77 - $0.26 = $41.51

Finally, on Friday, the cost goes down by $0.06.

So the expression to represent the cost of one share of the stock on Friday is:

$41.51 - $0.06

To evaluate this expression, we simply subtract $0.06 from $41.51:

$41.51 - $0.06 = $41.45

Therefore, the cost of one share of the stock on Friday is $41.45

Answer:

12

Step-by-step explanation:

The square root of 144 is 12. This is because when a number is squared, it means it is multiplied by itself. So, 12 multiplied by 12 is equal to 144. Therefore, the square root of 144 is the value that, when multiplied by itself, gives the result of 144. This value is 12. The square root of 144 is also a perfect square, which means it is a whole number that can be generated by multiplying two equal integers.

Step-by-step explanation:

The probability by the given data is 1%.

We are given that;

set α=0.01

Now,

The probability of making a type I error is the significance level, or alpha (α), which is the threshold we set for rejecting the null hypothesis124. It is also known as the false positive rate3.

If we set α=0.01, it means that we are willing to accept a 1% chance of making a type I error. Hence, the probability that we reject the null hypothesis when it was in fact true is 0.01 or 1%.

Therefore, by probability the answer will be 1%.

The ratio of the cost price and the printed price of the book is 1.2444.

We have,

Let's assume the printed price of the book = P.

As per the problem, the shopkeeper is selling the book at a discount of 10% on the printed price. So the selling price of the book.

= (P - 0.1P)

= 0.9P.

The shopkeeper earns a profit of 12% on selling the book.

So, the selling price of the book is also 112% of the cost price.

That is,

0.9P = 1.12C

where C is the cost price of the book.

Now, let's find the ratio of the cost price and the printed price of the book:

C/P

= (C/0.9P)/(P/0.9P)

= 1.12/0.9

= 1.2444

Therefore,

By completing squares, we can rewrite the quadratic equation as:

(x + 9)^2 = -9

Remember the perfect square trinomial:

(a + b)^2 = a^2 + 2ab + b^2

Here we have the quadratic equation:

x^2 + 103 = -18x + 13

We can rewrite this as:

x^2 + 18x = 13 - 103

x^2 + 18x = -90

x^2 + 2*9*x = -90

We can add 9^2 and subtract 9^2 to get:

x^2 + 2*9*x + 9^2 - 9^2= -90

(x^2 + 2*9*x + 9^2) - 9^2= -90

(x + 9)^2 - 81 = -90

(x + 9)^2 = -90 + 81

(x + 9)^2 = -9

The local maximum of f is at (-5/3, 128/27), and the local minimum is at (4/3, -64/27).

To find the neighborhood maxima and minima of the capability f(x) = (x-3)(x+1)(x+4), we really want to take its subordinate:

f'(x) = (x+1)(x+4) + (x-3)(x+4) + (x-3)(x+1)

f'(x) = [tex]3x^2 + 6x - 20[/tex]

Setting f'(x) equivalent to nothing and settling for x, we get:

[tex]3x^2 + 6x - 20 = 0x^2 + 2x - 20/3 = 0(x+5/3)(x-4/3) = 0[/tex]

Thusly, the basic focuses are x=-5/3 and x=4/3.

To decide the time periods and diminishing, we can utilize the principal subsidiary test. Since f'(x) is a quadratic capability with a positive driving coefficient, it is dependably certain for x < - 5/3 and x > 4/3, and consistently negative for - 5/3 < x < 4/3.

Thusly, f(x) is expanding on the spans (- ∞, - 5/3) and (4/3, ∞), and diminishing on the stretch (- 5/3, 4/3).

To find the nearby maxima and minima, we can utilize the subsequent subsidiary test. Taking the subordinate of f'(x), we get:

f''(x) = 6x + 6

Subbing x=-5/3 and x=4/3, we get:

f''(- 5/3) = - 2 < 0, so f has a neighborhood greatest at x=-5/3.

f''(4/3) = 10 > 0, so f has a neighborhood least at x=4/3.

Thusly, the neighborhood limit of f is at (- 5/3, 128/27), and the nearby least is at (4/3, - 64/27).

The measures of the angles add up to 180°, using that we can see that x = 10.

Now, notice that the 75° angle would be an adjacent angle to (11x - 5)°, then their measures add up to 180°, then we can write:

75° + (11x - 5)° = 180°

We can solve that for x.

75 + 11x - 5 = 180°

Answer:

Step-by-step explanation:

The situation that can be represented by the given equation 340 + 5x - 650 - 8x is:

Sierra started with savings of $340 and spends $8 of her savings every week. Brian started with savings of $650 and adds $5 to his savings every week. The equation represents the difference in savings between Sierra and Brian after x weeks. The term "340 + 5x" represents the total savings of Sierra after x weeks, where she starts with $340 and adds $5 per week. The term "- 650 - 8x" represents the total savings of Brian after x weeks, where he starts with $650 and subtracts $8 per week. By equating the two expressions, we can find the value of x, which represents the number of weeks needed for Sierra and Brian to have the same amount of savings.

The amount of commission Mr. A received last month is C = $ 417.62

Given data ,

Let the amount of commission earned be C

Now , the equation is

The first $1,500 in sales are eligible for a commission rate of 21%, so the commission on this portion of his sales is:

0.21 x $1,500 = $315

The remaining portion of his sales is:

$2,233 - $1,500 = $733

This amount is eligible for a commission rate of 14%, so the commission on this portion of his sales is

On simplifying the equation , we get

0.14 x $733 = $102.62

Step-by-step explanation:

First we set up the equation A(n)=-172 and substitute the given equation for A(n), giving us -172=8+(n-1)(-4). Simplifying, we get -180=(-4n+12), or -4n=-192, or n=48. However, n represents the number of terms in the sequence, and since the sequence starts with n=1, we need to subtract 1 from our answer to get the term number corresponding to A(n)=-172. Therefore, the answer is B) 46.

The value of test statistics is -0.87.

We have,

n=25, mean= 24.4, s=9.2 and a=.05

As t = (x - [tex]\mu[/tex])/(s/√(n))

t = (24.4 - 26)/(9.2/√(25))

t = -0.8695652173913

t = -0.87

The sample size is n = 25, so df= 25 - 1= 24

So, the probabilities for the one tailed test are 0.20 and 0.15 respectively.

A function f(x) = (x⁴ - 5x² + 4) / (x² + x - 2) is discontinuous at  x = 1 and x = -2. And it is a removable discontinuity.

Consider function f(x) = (x⁴ - 5x² + 4) / (x² + x - 2)

We factorise denominator as,

x² + x - 2

= x² + 2x - x - 2

= x(x + 2) - 1(x  + 2)

= (x  + 2)(x - 1)

So, the function f(x) becomes,

f(x) = (x⁴ - 5x² + 4) / ((x  + 2)(x - 1))

A function f(x) is discontinuous when the denominator of f(x) is zero.

i.e.,  (x  + 2)(x - 1) = 0

i.e., x = 1 or x = -2

Also, the factors of the polynomial x⁴ - 5x² + 4 are (x - 2), (x  + 2), (x - 1) and (x + 1)

We can write function f(x) as,

f(x) = (x⁴ - 5x² + 4) / (x² + x - 2)

f(x) = ((x - 2) (x  + 2) (x - 1) (x + 1)) / ((x  + 2)(x - 1))

f(x) = (x - 2)(x + 1)

Now, the function f(x) is continuous.
