The heights in inches of males in the united states are believed to be approximately normally distributed with mean u the mean h

vovikov84 [41]

Answer:

Standard error = 0.83

Step-by-step explanation:

Given that the heights in inches of males in the united states are believed to be approximately normally distributed with mean u

Sample mean for 25 adults randomly taken =

$\bar x = 69.72$ inches

Std deviation of sample s = $4.15$ inches

Since X the height of males is Normal we find that the sample mean also will follow a normal distribution.

By central limit theorem, mean of x would be= sample mean= 69.72

Std error = $\frac{s}{\sqrt{n} } =\frac{4.15}{5} \\=0.83$

Standard error of the mean = std dev/square root of sample size.

Here only sample std deviation is known

So we used it

Standard error = 0.83

Brandon earns a rebate each month on his meals and movie tickets. He earns $0.50 for each movie ticket and $2 for each meal. Las

AURORKA [14]

Let ticket be x and meal be y

So $0.50 for each movie ticket = 0.50x

$2 for each meal = 2y

He purchased 22 tickets, so x = 22

0.50 * 22 = $ 11

Now the total value is $25 (with both ticket and meal)

total = t

0.50x + 2y = t

you know x = 22 and t = 25

11 + 2y = 25

Part A)

2y = 25 -11

y = 14/2

y = 7

Number of meal is 7

Part B)

(don't know about part B)

0.50x + 2y = 25

0.50(22) + 2(7) = 25

11 + 14 = 25

25 = 25

Which polynomial correctly combines the like terms and expresses the given polynomial in standard form? 8mn5 Ă˘â‚¬"" 2m6 5m2n4 Ă

Pani-rosa [81]

The standard form of the polynomial function is $-6m^6+n^6+7mn^5+14m^2n^4-5m^3n^3$ .

The polynomial given is

$8mn^5-2m^6+5m^2n^4-m^3n^3+n^6-4m^6+9m^2n^4-mn^5-4m^3n^3$

Let us rearrange the expression as,

$-2m^6-4m^6+n^6+8mn^5-mn^5+5m^2n^4+9m^2n^4-m^3n^3-4m^3n^3$

Simplifying the above expression as,

$-6m^6+n^6+7mn^5+14m^2n^4-5m^3n^3$

The above expression of the polynomial function is in its standard form.

Hence, the standard form of the polynomial function is $-6m^6+n^6+7mn^5+14m^2n^4-5m^3n^3$ .
