Answer:

b = 10

Step-by-step explanation:

P = 2 (l + b)

l = 15

P = 50

Substitute

50 = 2 (15 + b)

multiply

50 = 30 + 2b

subtract

20 = 2b

divide

b = 10

<h3>Given:-</h3>

P = 2 (l + b) when l = 15 and P = 50

To find b

<h2>Solution:-</h2>

P = 2 (l + b) [Given]

Putting the value of P = 50 and l = 15 we get,

50 = 2(15 + b)

$\frac{50}{2}$ = 15 + b

25 = 15 + b

25 - 15 = b

10 = b

So, b = 10

<h3>Value of b is 10. [Answer]</h3>

Nya wants to buy a sweater that had an original price of $55. The sweater is now discounted 20% and the sales tax rate is 5.5%.

suter [353]

Answer:

$46.42

Step-by-step explanation:

a=price after discount (without sales tax)

a/55=20/100

100a=55·20

100a/100=1,100/100 (the 1,100 is from the 55·20)

You get 11 and then you have to subtract 11 from 55.

55-11=44, so a=44

Then you multiply 44·0.055 (you get 0.055 because you have to make 5.5% a decimal. You get 2.42.

You add 2.42 and 44 and you get $46.42

Reil [10]

Answer:

9/10

Step-by-step explanation:

the rule says

$\frac{a}{b} /\frac{c}{d} =\frac{ad}{bc}$

so in our case

a=3

b=4

c=5

d=6

so the division is

$\frac{3*6}{4*5} \\\\=\frac{18}{20}$

we can simplify

$\frac{18}{20} \\\\=\frac{2(9)}{2(10)} \\\\=\frac{9}{10}$

that's our answer

I don't know if you need step by step of the rule, if you need let me know

Answer:

b) Both 1,004 and 251 are greater than 10.

Step-by-step explanation:

p = 0.80

n = 1255

In order to use CLT the distribution of $\hat{p}$ should have np and n(1-p) greater than 10.

np = 1255*0.80

np = 1004

n(1-p) = 1255*0.20

n(1-p) = 251.00

Since Both 1004 and 251 are greater than 10,
