Answer:

x=0

Step-by-step explanation:

(x – 3)(x + 9) = –27

To get the solution we solve for x

(x – 3)(x + 9) = –27

USe FOIL method to multiply (x – 3)(x + 9)

x^2 +9x-3x-27

x^2 + 6x - 27

(x – 3)(x + 9) = –27

x^2 + 6x - 27=-27

Add 27 on both sides

x^2 + 6x=0

x(x+6)=0

x=0 and x+6 =0

x=0 , x=-6

So x=0 is one of the solution

Answer: To solve this question, you would first measure yourself and your self and your shadow, and then the shadow of the tower while the sun is in spot in the sky, you will then use the ratio (your height/your shadow) = (towers height/ towers shadow)

You will then cross multiply and divide to find the towers height

On Monday the price of a company’s stock is $30 per share. On Tuesday, the stock price drops $3, on Wednesday it rises $7, on Th

erastova [34]

Answer:

The price at the end of the week is $33.

Step-by-step explanation:

We are given that on Monday the price of a company’s stock is $30 per share. On Tuesday, the stock price drops $3, on Wednesday it rises $7, on Thursday it rises $3, and on Friday it drops $4.

The price of a company’s stock on Monday = $30 per share

So, the mathematical statement that represents the situation is given by;

Price of company’s stock on Monday = $30

On Tuesday, the stock price drops $3, so the price of company’s stock on Tuesday = Price of company’s stock on Monday - Drop in price on Tuesday

= $30 - $3 = $27

On Wednesday, the stock price rises $7, so the price of company’s stock on Wednesday = Price of company’s stock on Tuesday + Rise in price on Wednesday

= $27 + $7 = $34

On Thursday, the stock price rises $3, so the price of company’s stock on Thursday = Price of company’s stock on Wednesday + Rise in price on Thursday

= $34 + $3 = $37

On Friday, the stock price drops $4, so the price of company’s stock on Friday = Price of company’s stock on Thursday - Drop in price on Friday

= $37 - $4 = $33

Hence, the price at the end of the week is $33.

For bone density scores that are normally distributed with a mean of 0 and a standard deviation of 1, find the percentage of sc

Shkiper50 [21]

Answer:

a) Scores of 2 and higher are significantly high

b) Scores of -2 and lower are significantly low

c) Scores between -2 and 2 are not significant.

Step-by-step explanation:

Mean = 0

Standard deviation = 1

a. significantly high (or at least 2 standard deviations above the mean).

2 standard deviations above the mean is:

0 + 1*2 = 2

So scores of 2 and higher are significantly high

b. significantly low (or at least 2 standard deviations below the mean).

2 standard deviations below the mean is:

0 - 1*2 = -2

So scores of -2 and lower are significantly low

c. not significant (or less than 2 standard deviations away from the mean).

2 standard deviations above the mean is:

0 + 1*2 = 2

2 standard deviations below the mean is:

0 - 1*2 = -2

So scores between -2 and 2 are not significant.
