Answer:

<em>165ft</em>

Step-by-step explanation:

Ratio of actual walkway and a model is :

60 ( Ft ) : 15 ( in) or : 15 : 1

EF = 60 Ft,

FG = 30 Ft,

GH = 30 Ft,

HE = 45 Ft.

60 + 30 + 30 + 45 = 165 Ft

The margin of error can be calculated with the formula:

ME = z · √(p(1-p)/n)

where:
p = sample proportion
n = sample size
z = z-score

In your case:
p = 90 / 120 = 0.75

ME = 2.58 · √(0.75·0.25/120)
= 0.10
= 10%

The margin of error will be 10%.

Members of a junior high basketball team want to brag about how tall they are. First, they measured each player’s height in inch

enyata [817]

First to find the median we need to put the numbers in order from least to greatest.

62, 64, 65, 66, 67, 69, 83

Now take a number from each side

64, 65, 66, 67, 69

Once again.

65, 66, 67

On last time

66

So the median is 66.

Now to find the mean we must add all the numbers up

64+67+83+65+66+62+69

which equals 476

Now divide 476 by the total number of heights which is 7

476/7=68

So the mean is 68

Answers: Mean; 68 Median; 66

At 11:00 a.M., there are 400 members and 150 non-members visiting a museum. After 11:00 a.M., 10 members leave every five minute

alexdok [17]

Answer:

$16:27$

Step-by-step explanation:

GIVEN: At $11:00\text{ A.M.}$ , there are $400$ members and $150$ non-members visiting a museum. After $11:00\text{ A.M.}$ , $10$ members leave every five minutes and $5$ non-members arrive every five minutes.

TO FIND: ratio of members to non-members at $1:00\text{ P.M.}$

SOLUTION:

Total number of members in museum at $11:00\text{ A.M.}$ $=400$

as after every $5$ minutes $10$ members leave

total number of $5$ minutes interval in $2$ hour $=\frac{60}{5}=12$

total members at $1:00\text{ P.M.}$ $=400-10\times24$

$=160$

Total number of non-members in museum at $11:00\text{ A.M.}$ $=150$

as after every $5$ minutes $5$ non-members arrive

total number of $5$ minutes interval in $2$ hour $=\frac{60}{5}=12$

total non-members at $1:00\text{ P.M.}$ $=150+5\times24$

$=270$

ratio of members to non-members at $1:00\text{ P.M.}$ $=\frac{\text{number of members}}{\text{number of non-members}}$

$=\frac{160}{270}$

$=\frac{16}{27}$

Hence the ratio of members to non-members at $1:00\text{ P.M.}$ is $\frac{16}{27}$
