The meters of fencing that is needed is = 3.36m

The garden is designed in a trapezoid form with sides= a; 3.3m and b; 5.28m.

The area of the trapezoid garden = 13.92 m²

Therefore the meters of fencing needed which is height = ?

The formula for the area of trapezoid = A = (a+b/2)h

From the formula make h the subject of formula;

h = A *2/a+b

h = 13.92*2/3.3+5.28

h =27.84/8.28

h= 3.36m

Therefore, the meters of fencing that is needed is = 3.36m.

The best estimate of the profit when 350 pounds of food are produced is $5300

The quadratic regression is given as:

[tex]f(x) = -0.0817x^2 + 102.24x - 20421[/tex]

When 350 pounds are produced, it means that:

x = 350.

So, we have:

f(350) = -0.0817(350)^2 + 102.24(350) - 20421

Evaluate

f(350) = 5354.75

Approximate

f(350) = 5300

Hence, the best estimate is $5300

Answer:

10.16

Step-by-step explanation:

average change =  9.16 - 4.35 / 2020 - 1996  = 0.2

Cost = 9.16 + (2025 -2020) x 0.2 = 10.16

So the answer is $10.16

Answer:

0.2 = 1/5

0.333 = 1/3

-1.000001 = -1 1/1000000

-√4 = -2

3√1000 = 30

48/6=8$

Answer:

I think it's

G: 71

H: 109

K: 151

M: 29

Step-by-step explanation:

This shows many straight angles, which we can use to find the answers.

H and 71 are on one, every right angle is 180 degrees, so we subtract 71 from 180 and get 109. G and 71 are vertical angles which makes them the same, therefore G is also 61.

M and 151 are on another straight angle, so we do the same thing, subtract 151 from 180 and we get 29. There is a line under that and M and the little unmarked angle are vertical angles so they are the same making the little one 29, making K also 151.

Answer:

f(3) = 2

Step-by-step explanation:

Remark

The formula starts out as

f(x)= 2x - 4        

So what is telling you is that were ever you see a variable on the right, it can from the x on the left.

If you change the variable on the left, you must also do it on the right.

f(3) = 2*3 -4

f(3) = 6-4

Answer:

19.00 x h + 25.00 =

What you make in a day if you work for h hours.

Step-by-step explanation:

You automatically make $25.00 when you show up.

So the equation is asking for how many hours. If you get $19 per hour

then it would be $19.00 x h (how many hours you worked) + $25.00.

Example:

If you worked for 5 hours and one day, then the equation would be

19.00 x 5= 95

95 + 25 (for showing up that day) = 120

So if you worked 5 hours for one day you would make 120

(This was just an example to further explain how the equation worked)

therefore we know that..

2x+5x = 21

on solving for x,

7x=21

x= 21/7

x=3

now, by putting the value of x in (i),

2x = 2×3 = 6

therefore, there are 6 boys in the classroom.

Answer:

C) 20.97 AED

Step-by-step explanation:

To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as [tex]\displaystyle E(X)=\mu=\sum xP(x)[/tex].

Here, x represents values of the random variable X, [tex]P(x)[/tex] represents the corresponding probability, and symbol [tex]\displaystyle \sum[/tex] represents the sum of all products [tex]xP(x)[/tex]. Here we use the symbol [tex]\mu[/tex] for the mean because it is a parameter. It represents the mean of a population.

In this case, the expected value of the ticket is [tex]\displaystyle E(X)=\mu=\sum xP(x)=12(0.08)+18(0.15)+20(0.31)+22(0.08)+24(0.15)+25(0.23)=20.97[/tex]

This means that Ahmad can expect to win 20.97 AED for the ticket.
