Answer:

c. II and III

Explanation:

Anna begins with $274. On Monday, she has a debit of 194.62 followed by a credit of 35.45:

274-194.62 = 79.38 + 35.45 = $114.83

This is not a negative balance, so there is no overdraft.

On Tuesday, she has no debits and a credit of 11.20:

$114.83 + 11.20 = $126.03

No negative balance means no overdraft fee.

On Wednesday, she has a debit of 145.86 and a credit of 24.75:

126.03 - 145.86 = -19.83 + 24.75 = $4.92

No negative balance means no overdraft fee.

On Thursday, she has a debit of 53.35 and a credit of 33.80:

4.92 - 53.35 = -48.43 + 33.80 = -14.63

This is a negative balance, so Anna will have an overdraft fee on Thursday.

On Friday, she has a debit of 31.60 and a credit of 45.77:

-14.63 - 31.60 = -46.23 + 45.77 = -0.46

This is a negative balance, so Anna will have an overdraft fee on Friday.

On Saturday, she has a debit of 12.90 and a credit of 61.63:

-0.46 - 12.90 = -13.36 + 61.63 = $48.27

No negative balance means no overdraft fee.

This means she overdrafts on Thursday and Friday.

A food company originally sells cereal in boxes with dimensions 25 cm by 14 cm by 10 cm. To make more profit, the company decrea

hjlf

Answer:

1.75 cm

Step-by-step explanation:

We are given that the dimensions of the box as 25 cm by 14 cm by 10 cm.

Now, to increase the profit, the dimensions of the box by 'x' cm.

Thus, the new dimensions are (25-x) cm by (14-x) cm by (10-x) cm.

Further, it is given that the volume of the new box is 2,208 $cm^{3}$

As, Volume of the box = Length × Breadth × Height

i.e. 2208 = (25-x) × (14-x) × (10-x)

i.e. $2208 = (25-x) \times (140-24x-x^{2})$

i.e. $2208=x^{3}-x^{2}-740x+3500$

i.e. $x^{3}-x^{2}-740x+1292=0$

On solving this cubic equations, we get that, the solutions are x = 27.6, x = 1.75 and x = 26.8.

Since, the dimensions 25 cm by 14 cm by 10 cm are reduced by x cm.

Thus, if x = 27.6 or x = 26.8, then (10-x) = -17.6 or -16.8, which cannot be possible. So, x = 1.75 cm.

Hence, the dimensions were decreased by 1.75 cm.

The probability of saving a penalty kick from the opposing team is .617 for a soccer goalie. If 7 penalty kicks are shot at the

dsp73

Answer:

0.2754

Step-by-step explanation:

Probability of saving a penalty kick = 0.617

p = 0.617 ; q = 1 - p = 1 - 0.617 = 0.383

number of trials, n = 7

Number of saves, x = 5

Using the binomial probability relation :

P(x = x) = nCx * p^x * q^(n-x)

P(x = 5) = 7C5 * 0.617^5 * 0.383^2

P(x = 5) = 21 * 0.0894181 * 0.146689

P(x = 5) = 0.2754

Find the value of this expression if x= 9. x square + 6 over x-6.

torisob [31]

Hold on, does the equation look like this? (x^2+6)/x-6? Because if so then you'd substitute nine for x first. Then you'd multiply nine by itself getting eighty-one, after that add six to get eighty-seven. substitute nine for x one more and subtract six. take eighty-seven divided by three to get an answer of twenty-nine. But if the equation is saying the square of nine aside from nine squared then you'd have an entirely different problem. That one would look similar to *square symbol*(9)+6/9-6
, You'd solve this by finding the square of nine which is three then you'd add six and get a numerator of nine. Then you go about the bottom the same as you would have in the first equation, subtract six from nine giving you a denominator of three so you now have nine over three which simplified is three.

The two answers are 29 or 3 depending on the equation.

Uncle Joe is cutting boards for bookshelves. If he begins with 9 feet of wood, how many shelves will he cut if each one is 1 1/2

kherson [118]

To get the answer, you divide the length of the board by the size of the pieces wanted, so the equation you get is

9/1.5 = 6

So you can get six 1.5in shelves from a 9ft board
