Answer:

4. 7/9 (b - 27) > 49/81

=> 7/9b - 21 > 49/81

=> 7/9b - 21 > 7/9

=> 7/9b -21 + 21 > 7/9 + 21

=> 7/9b > 7/9 + 189/9

=> 7/9b > 196/9

=> 7/9b / 7/9 > 196/9 / 7/9

=> To divide fractions, take the reciprocal of the divisor fraction and then multiply.

=> b > 196/9 x 9/7

=> b > 1764 / 63

=> b > 28

4th answer is b > 28

5. This question doesn't make any sense.

=> 11w - 8w greater or equal to 14w

=> 3w greater or equal to 14w.

If we make "w" as any number, this equation will not come true as 14 is larger than 3.

This answer may be correct the equation is like:

3w is smaller or equal to 14w.

Answer:

b > 250/9 and w ≥ 0

Step-by-step explanation:

7/9 (b - 27) > 49/81

First, simplify both sides of the inequality:

7/9b - 21 > 49/81

Add 21 to both sides

7/9b - 21 +21 > 49/81 +21

Multiply both sides by 9/7

9/7 x 7/9b > 49/81 x 9/7

b > 1750/81

Simplify

b > 250/9

11w - 8w ≥ 14w

Simplify both sides once again

3w ≥ 14w

Subtract 14w from both sides

3w - 14w ≥ 14w - 14w

-11w ≥ 0

Divide both sides by -11w

w ≥ 0

The meaning of this problem is that with 7 nurses they can only hire D=13.25

<h3>What is the meaning of this problem.?</h3>

Generally, the equation for the model is mathematically given as

$P=1000D^{0.6}N^{0.3}$

Therefore,

$dv/dD=0.6*1000*D^{0.4}N)^{0.3}$

$dv/dD=600* \frac{N6.1}{D6.1}=0$

Also

$dv/dN=300* \frac{N6.8}{N6.7}=0$

Equations 1 and 2

$300* \frac{D6.8}{N6.7}=600* \frac{N6.1}{D6.1}$

.sub D=(60N)/4

$300* \frac{((60N)/4)6.8}{N6.7}=600* \frac{N6.1}{((60N)/4)6.1}$

N=6.67

N=7

solve for D

D=(60(7))/4

D=13.25

In conclusion, with 7 nurses they can only hire D=13.25

What is the sixth term of the sequence an=-3•2n+1<br>a6=

muminat

Answer:

$a_6=-384$

Step-by-step explanation:

The $n^{th}$ term of the sequence is given as $a_n=-3\cdot 2^{n+1}$ .

To find the sixth term, which is denoted by $a_6$ , we substitute n=6 into the given rule.

This will give us:

$a_6=-3\cdot 2^{6+1}$

Simplify the exponent to get:

$a_6=-3\cdot 2^{7}$

We simplify further to get:

$a_6=-3\cdot 128$

This simplifies to

$a_6=-384$

Answer #1 please ASAP

Ad libitum [116K]

Answer:

4.5

Step-by-step explanation:

To find the median, put the data in order from smallest to largest

1,2,2,3,4,4,5,5,8,10,10,11

The count up the number of data points

Divide by 2

12/2

Split the data into 2 groups, 6 in each, starting at the beginning

1,2,2,3,4,4, 5,5,8,10,10,11

Since there is an even number

Add the last number in first group and the first number in the last group and divide by 2

(4+5)/2 = 9/2 = 4.5

The median is 4.5
