Answer:

The answer is "6.635776".

Step-by-step explanation:

If the proportion estimation is not given, then the approximate is true. So, it is in the top condition, which referring its overall error margin that is equal to 0.5.  

Therefore the margin of error=0.05   With z=2.576  

[tex]\to 0.05=2.576 \times \sqrt{(0.05 \times \frac{0.05}{N})}\\\\\to 0.05=2.576 \times \sqrt{( \frac{0.0025}{N})}\\\\\to \sqrt{N}= \frac{2.576 \times 0.05}{0.05}\\\\\to \sqrt{N}= 2.576[/tex]

square the above equation:

[tex]\to (N)^2= (2.576)^2\\\\\to N^2= 6.635776\\\\[/tex]

So the number of required residents=6.635776

Complex my way

Answer:   The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon. 1,440/10 = 144.

Answer:

Number of Nickels = 19

Number of pennies = 5

Step-by-step explanation:

The type of coins that Janessa has = nickels and pennies.

Janessa has a total number of 24 coins

The sum of the nickels and pennies = $1.00

Let us represent the number of nickels as x

The number of pennies as y

Hence, our system of equations is :

x + y = 24..... Equation 1

x = 24 - y

A nickel is worth 5 cents.

1 nickel = $0.05

A penny is worth 1 cent.

1 penny = $0.01

Therefore,

$0.05× x + $0.01 × y= $1.00

0.05x + 0.01y = 1.00........Equation 2

Substitute 24 - y for x in Equation 1

0.05(24 - y) + 0.01y = 1

1.2 - 0.05y + 0.01y = 1

1.2 - 1 = 0.05y - 0.01y

0.2 = 0.04y

y = 0.2/0.04

y = 5

We have 5 pennies

x = 24 - y

x = 24 - 5

x = 19

We have 19 nickels

Answer:

[tex]x \leq 1[/tex]

Step-by-step explanation:

Write it out:

[tex]\frac{1}{2} -\frac{1}{4}x \geq \frac{1}{4}[/tex]

Get x alone

Subtract 1/2 from both sides

[tex]-\frac{1}{4} x \geq -\frac{1}{4}[/tex]

Divide both sides by -1/4 (NOTE: Dividing by a negative you must flip the sign)

[tex]x \leq 1[/tex]

(170 - 50)/8 = X

Step-by-step explanation:

X = amount of people

(170 - 50)/8 = X

Inequality

X = Number of People

50+(8*X) [tex]\leq[/tex] 170

The x statement is x ≤ 15. An inference is a statement that expresses the relationship between two (or more) expressions using one of the five signs listed below.

Therefore,

(170 - 50)/8 = X

X = Number of People Over 50 (170 - 50)/8 = X

Inequality (8 × X) ≤ 170

An inequality is a statement that expresses the relationship between two (or more) expressions using one of the five signs listed below.

Answer:$15 = 100 x rate x (2/52)

The 2/52 represents 2 weeks out of 52 weeks in a year

So 15/100 = rate x (2/52)

.15 = rate x (2/52)

If you divide by (2/52) on both sides, you get: 3.9 = rate

Don't be fooled by this answer, because it is not in percent form. In order to get it into percent form you need to multiply by 100. So the percent of interest paid on the loan is 390%.

In a lot of these problems you can predict around the percentage before you even do the problem. In this problem, you can tell that the percentage is going to be high because the loan has accrued $15 interest in just two weeks (15% in just two weeks!)

So if there is 15% interest in two weeks, you know it is going to be a very high annual percentage.

Answer:

C. Yes, because the ratios are equivalent between each pair of values.

Step-by-step explanation:

A relationship between two quantities is proportional if the ratio of the two quantities are the same for all the given possible pairs of values.

In the table given, the ratio of block to mins in the first given pair of values is 3/6 = 3/6 = ½.

In the second given pair, it is 7 to 14 = 7/14 = ½. The same ratio is gotten for the others as well.

Therefore, the table represents a proportional relationship.

The answer is: "C. Yes, because the ratios are equivalent between each pair of values."

Answer:

The greatest number of identical arrangements is 6 units of 9 roses and 7 tulips each.

Step-by-step explanation:

Tulips represent the limiting quantity. In this case, the easiest and most effective approach is determining the ratio of roses to tulips to get how many roses must be left along with a minimum quantity of tulips in a unit. That is:

[tex]x = \frac{54\,roses}{42\,tulips}[/tex]

[tex]x = \frac{27\,roses}{21\,tulips}[/tex]

[tex]x = \frac{9\,roses}{7\,tulips}[/tex]

The greatest number of identical arrangements is 6 units of 9 roses and 7 tulips each.

Answer:

x=4

Step-by-step explanation:

it tel you that f(x) = 7 so replace "f(x)" for 7 in the equation. You then get 7 = 4x - 9 so now you solve for x. You have to isolate x so you add 9 to the other side since you do the opposite of -9. Once you add 9 and 7, then divide the answer by 4. You should get 4 = x.

Work:

f(x) = 4x - 9

7 = 4x - 9

7 + 9 = 4x

16 = 4x

16 ÷ 4 = x

4 = x

Answer:

There is something wrong with the question because you cannot earn more interest during a year than the principal if you earn only 9% or 11%. You would have to earn more than 100%, so I will do this calculation based on $17,170 (not $171,700) earned in interest per year.

let S = amount received from short term note, and L = amount received from long term note

0.11S + 0.09L = 17170

S + L = 170000

S = 170000 - L

0.11 (170000 - L) + 0.09L = 17170

18700 - 0.11L + 0.09L = 17170

1530 - 0.02L = 0

1530 = 0.02L

L = 1530 / 0.02 = $76,500

S = 170000 - 76500 = $93,500

Answer:

Experimental but not double-blinded study

Step-by-step explanation:

The type of study being described is an Experimental but not double-blinded study. That is because it is a study that has a control group, dependent variable, and an independent variable all used in order to acquire specifically targetted data from the results that are derived from the experiment itself. Also since the scientists/researchers know exactly which lab sections are getting the extra review material (independent variable), then that makes this a non-double-blinded study.

Answer:

d = 1.67 miles

Step-by-step explanation:

Given that,

Speed of a person,  [tex]s=3\dfrac{1}{3}\ mph[/tex]

We need to find how many miles can you walk in 30 minutes, given the  same pace.

30 minutes = 0.5 h

[tex]3\dfrac{1}{3}\ mph = \dfrac{10}{3}\ mph[/tex]

Speed = distance/time

[tex]d=v\times t\\\\d=\dfrac{10}{3}\ mph\times 0.5\ h\\\\d=1.67\ miles[/tex]

So, the person will cover a distance of 1.67 miles

The equation of the line is equal to y=-5x/4 +c

The slope-intercept form of a line is represented by y=mx+c where m=slope and c is the y-intercept of the line

Given here: The given line passes through (4,6) and (9,2)

We know the slope intercept form is given by

y=mx+c

putting (4,6)  in the equation we get

6=4m+c

Again substituting (9,2) in the equation we get

2=9m+c

Thus solving this two equations we get the value of m=-5/4 and c=11

Hence, The equation of the line is equal to y=-5x/4 +c
