​

Answer:

162m²

Step-by-step explanation:

distance from corner to center = 1/2 of the diagonal

all sides are equal, and this has 4 sides, so it is a square

9m = 1/2 of diagonal

multiply both sides by 2 to isolate the diagonal

18m = diagonal

area of square = length²

length * √2 = diagonal

given the diagonal, we can find the length and then the area

length * √2 = diagonal

divide both sides by √2 to find the length

18m/√2 = length ≈12.7

square the length to find the area

area = 162 m²

Answer:

-2

Step-by-step explanation:

f(2)= 2^2 + 2(2) - 10

The measure of each arc.

a. JL =  132

b. KM =147

c. JLM = 200

d. JM =120

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint.

The measure of JL

=m JK+ m KL

= 53+79

= 132

The measure of KM

=m KL+ m LM

= 79+68

=147

The measure of JLM

= 53+68+79

= 200

The measure of JM

=360-200

=120

The margin error is 2.82%.

A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample

The margin of error for a sample proportion is given by

[tex]z_{\alpha /2}\sqrt{ \frac{p(1-p)}{n} }[/tex]

where p is the sample proportion and n is the sample size.

Consider the  confidence level of 95%, then  [tex]z_{\alpha /2}[/tex] = 1.96

p = 53% = 0.53 and n =1200

Thus, Margin of error=

[tex]z_{\alpha /2}\sqrt{ \frac{p(1-p)}{n} }[/tex]

=1.96[tex]\sqrt{ \frac{0.53(1-0.53)}{1200} }[/tex]

=1.96*0.0144

=0.0282

= 2.82%

Hence, margin error is  2.82%.

Answer:

(z+7)*(z+4)

Step-by-step explanation:

The first term is,  z2  its coefficient is  1 .

The middle term is,  +11z  its coefficient is  11 .

The last term, "the constant", is  +28

Step-1 : Multiply the coefficient of the first term by the constant   1 • 28 = 28

Step-2 : Find two factors of  28  whose sum equals the coefficient of the middle term, which is   11 .

     -28    +    -1    =    -29

     -14    +    -2    =    -16

     -7    +    -4    =    -11

     -4    +    -7    =    -11

     -2    +    -14    =    -16

     -1    +    -28    =    -29

     1    +    28    =    29

     2    +    14    =    16

     4    +    7    =    11    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  4  and  7

                    z2 + 4z + 7z + 28

Step-4 : Add up the first 2 terms, pulling out like factors :

                   z • (z+4)

             Add up the last 2 terms, pulling out common factors :

                   7 • (z+4)

Step-5 : Add up the four terms of step 4 :

                   (z+7)  •  (z+4)

            Which is the desired factorization

Answer: Choice G   [tex]\left| \frac{p-n}{n} \right|[/tex]

============================================================

Explanation:

Pick a positive number for p, and a negative value for n. Make sure that p is further away from 0 than n is (so that [tex]|p| > |n|[/tex] is a true statement).

I'll go for these values

Replace every copy of p with 5, and replace every copy of n with -2. Then evaluate or simplify. Use your calculator if needed.

Let's start with choice F.

[tex]F = \left| \frac{p-n}{p} \right|\\\\F = \left| \frac{5-(-2)}{5} \right|\\\\F = \left| \frac{5+2}{5} \right|\\\\F = \left| \frac{7}{5} \right|\\\\F = \left| 1.4 \right|\\\\F = 1.4\\\\[/tex]

Now onto choice G

[tex]G = \left| \frac{p-n}{n} \right|\\\\G = \left| \frac{5-(-2)}{-2} \right|\\\\G = \left| \frac{5+2}{-2} \right|\\\\G = \left| \frac{7}{-2} \right|\\\\G = \left| -3.5 \right|\\\\G = 3.5\\\\[/tex]

Next up is evaluating the expression for choice H.

[tex]H = \left| \frac{p+n}{p-n} \right|\\\\H = \left| \frac{5+(-2)}{5-(-2)} \right|\\\\H = \left| \frac{5-2}{5+2} \right|\\\\H = \left| \frac{3}{7} \right|\\\\H \approx \left| 0.4286\right|\\\\H \approx 0.4286\\\\[/tex]

Then let's compute expression J.

[tex]J = \left| \frac{p+n}{p} \right|\\\\J = \left| \frac{5+(-2)}{5} \right|\\\\J = \left| \frac{5-2}{5} \right|\\\\J = \left| \frac{3}{5} \right|\\\\J = \left| 0.6 \right|\\\\J = 0.6\\\\[/tex]

Lastly, compute expression K.

[tex]K = \left| \frac{p+n}{n} \right|\\\\K = \left| \frac{5+(-2)}{-2} \right|\\\\K = \left| \frac{5-2}{-2} \right|\\\\K = \left| \frac{3}{-2} \right|\\\\K = \left| -1.5 \right|\\\\K = 1.5\\\\[/tex]

-----------------------------------

To summarize, when plugging p = 5 and n = -2 into each expression, we got these results:

Expression G leads to the largest output.

Therefore, [tex]\left| \frac{p-n}{n} \right|[/tex] has the largest value when p > 0 and n < 0.

The expression |(p-n)/n| has the greatest value. Therefore, option G is the correct answer.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, p is a positive number, n is a negative number, and |p| > |n|.

Let us consider p=5 and n=-2

Now,

F) |(p-n)/p|

= |(5-(-2))/5|

= |7/5|

= 1.4

G) |(p-n)/n|

= |(5-(-2))/(-2)|

= |7/(-2)|

= 3.5

H) |(p+n)/(p-n)|

= |(5-2)/(5-(-2))|

= |3/7|

= 0.43

J) |(p+n)/p|

= |(5-2)/5|

= |3/5|

= 0.6

K) |(p+n)/n|

= |(5-2)/2|

= |3/2|

= 1.5

The expression |(p-n)/n| has the greatest value. Therefore, option G is the correct answer.

Answer: 5 hours

Step-by-step explanation:

[tex]speed=\frac{distance}{time}[/tex]

Andy speed = 7.5/3 = 2.5 mph

William speed = 15/4 = 3.75 mph

1. Write an equation that represents the question

let h = # of hours it takes William to catch up with andy

   2.5h + 6.25 = 3.75h

2. subtract 2.5h from both sides

   6.25 = 1.25h

3. Divide 1.25 from both sides

   [tex]\frac{1.25h}{1.25} =\frac{6.25}{1.25}[/tex]

   h = 5

Therefore, we know it will take 5 hours for William to catch up with andy.

The distance from the centre of the ground to the boundary based on the area given is 93.58 meters.

From the information given, the area of a round cricket oval is 27500 square meters. The information simply wants us to calculate the radius which will be calculated thus:

Area of a circle = πr²

πr² = 27500

(3.14) × r² = 27500

r² = 27500/3.14

r² = 8757.96

r = ✓8757.96

r = 93.58

Therefore, the distance from the centre of the ground to the boundary is 93.58 meters.

Step-by-step explanation:

If 21 people study French and everyone studies some language, then the other 4 people must be Spanish only students. 25 - 21 =4

Since 13 people study Spanish,

13-4=9

9 people must study both Fr and Sp.

If 9 people study BOTH, then

21-9=12,

12 people must be the Fr only people.

The arch-looking, upsidedownU is intersect.

Fr intersect Sp are the StudyBOTH people.

P(Both) = Both/Total

= 9/25

If you need %, divide 9÷25 and times by 100. That's 36%

F' means Not French people, which is Spanish only people (thankfully there are no No-Language-studiers bc they would count too)

P(F')
