(4x² - 3x - 4) - (3x² + 4x - 8) ← distribute by - 1

= 4x² - 3x - 4 - 3x² - 4x + 8 ← collect like terms

= x² - 7x + 4 → B

Step-by-step explanation:

(4 {x}^{2}  - 3x - 4) - (3 {x}^{2}  + 4x - 8) \\  \\  = 4 {x}^{2}  - 3x - 4 - 3 {x}^{2}  - 4x + 8 \\  \\  = 4 {x}^{2}  - 3 {x}^{2}  - 3x - 4x - 4 + 8 \\  \\  =  {x}^{2}  - 7x + 4

Thus option B is the correct answer.

The sale bin in a clothing store contains an assortment of t-shirts in different sizes. There are 7 small, 8 medium, and 4 large
umka21 [38]

Answer:

P(at least 1 large) = 0.648

P(at least 1 large) = 64.8%

Step-by-step explanation:

We have 7 small shirts, 8 medium shirts and 4 large shirts

Total number of shirts = 7 + 8 + 4 = 19 shirts

The probability that at least one of the first four shirts he checks is a large is given by

P(at least 1 large) = 1 - P(no large)

So first we need to find the probability that the none of the first four shirts he checks are large.

For the first check, there are 15 small and medium shirts and total 19 shirts so,

15/19

For the second check, there are 14 small and medium shirts and total 18 shirts left so,

14/18

For the third check, there are 13 small and medium shirts and total 17 shirts left so,

13/17

For the forth check, there are 12 small and medium shirts and total 16 shirts left so,

12/16

the probability of not finding the large shirt is,

P(no large) = 15/19*14/18*13/17*12/16

P(no large) = 0.352

Therefore, the probability of finding at least one large shirt is,

P(at least 1 large) = 1 - P(no large)

P(at least 1 large) = 1 - 0.352

P(at least 1 large) = 0.648

P(at least 1 large) = 64.8%

1. A survey of visitors at a national park was conducted to determine the preferred
fiasKO [112]

Using proportions, it is found that the correct statement is:

D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

In this problem, the table is from a sample of 80 visitors.

Since the <u>proportions stay the same</u>, just the number of visitors change, the correct statement is given by:

D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports.

As from the 80 students, 28 prefer camping and 14 prefer water sports, hence from 200, these numbers will be of 70 and 35 respectively.
