The height distribution of NBA players follows a normal distribution with a mean of 79 inches and standard deviation of 3.5 inch

Shtirlitz [24]

Answer:

The probability will be "0.0111".

Step-by-step explanation:

The given values are:

Mean,

$\mu$ = 79

Standard deviation,

$\sigma$ = 3.5

Now,

⇒ $\sigma\bar x = \frac{\sigma}{\sqrt n}$

$= \frac{3.5}{\sqrt 16}$

$=0.875$

⇒ $P(\bar x > 81) = 1 - P(\bar x < 81)$

So,

= $1 - P{\frac{(\bar x - \mu \bar x )}{ \sigma \bar x} < \frac{(81 - 79) }{0.875} ]$

= $1 - P(z < 2.2857)$

= $0.0111$

Solve each system by elimination.

meriva

Answer:

4.)

a. x= -6 y-3

b. x= 5 y + 13

4 4

3.)

a. x= -4y + -8

5 5

b. x= 3 y+3

Step-by-step explanation:

4.)

a. 5x+6y=-15

Add -6y to both sides.

5x+6y+−6y=−15+−6y

5x=−6y−15

Divide both sides by 5.

5x ÷ 5= -6y-15 ÷5

x= -6 y-3

b. 4x - 5y=13

Add 5y to both sides

4x−5y+5y=13+5y

4x=5y+13

Divide both sides by 4

4x÷4= 5y+13÷4

x= 5 y + 13

4 4

5.)

a. (5x+4y=-8)

Add -4y to both sides

5x+4y+−4y=−8+−4y

5x=−4y−8

Divide both sides by 5

5x÷5= -4y-8÷5

x= -4y + -8

5 5

b. 2x - 3y = 6

Add 3y to both sides.

2x−3y+3y=6+3y

2x=3y+6

Divide both sides by 2.

2x÷2= 3y+6÷2

x= 3y+3

<h3>What are employees' benefits?</h3>

Employee perks and benefits in kind are non-wage compensation provided to employees in addition to their regular income or salary.
A "salary package" or "salary exchange" arrangement is one in which an employee exchanges salaries for some other type of compensation.

To find Lakisha's total job benefits:

If Lakisha's employer pays $2,150 in health insurance and $86 in life insurance per year, and she also gets $3,520 in paid time off per year, then Lakisha's total job benefits per year are equal to:

Total Benefits = Health Insurance + Life Insurance + Paid Time Off + Annual Gross Pay

Total Benefits= $2,150+$86+$3,520+12($4,370)
Total Benefits= $2,150+$86+$3,520+$52,440
Total Benefits=$58,196

Therefore, Lakisha's total job benefits per year are (D) $58,196.
