Jimmy’s family moved to a tropical climate. For the year that followed, he recorded the number of days that had a temperature above 40 degrees C each month. His data contained -
14, 14, 10, 12, 11, 13, 11, 11, 14, 10, 13 and 8

For problems 1-8, use the data set below.

1) Find the mean for his data set of days that had a temperature above 40 degrees C.

Answer:

\(-\frac{65}{28}\) or \(-2\frac{9}{28}\)

Step-by-step explanation:

Add all fractions:

\(-1\frac{3}{4}\) + \(-\frac{1}{28}\) + \(-\frac{15}{28}\) = \(-\frac{65}{28}\)

Simplify if needed:

\(-\frac{65}{28}\) = \(-2\frac{9}{28}\)

I took some paper and cut it to the shapes and folded them to see which ones are the answer and got those 2. :3

Answer:

y=

\( \frac{2}{15} \)

x+10

Step-by-step explanation:

we know the y-intercept : (0,10)

picking another point on the line, (2,25)

finding slope is

\( \frac{y2 - y1}{ x2 - x1} \)

so inserting that together is:

\( \frac{2 - 0}{25 - 10} \)

that equals to,

\( \frac{2}{15} \)

and since we already have the y-intercept you take the 10 to replace the b in the equation y=x+b

meaning x = slope and b = y-intercept

equation all together

y =

\( \frac{2}{15} \)

x + 10

Answer:

  see attached

Step-by-step explanation:

The Pythagorean theorem can be used to find the hypotenuse associated with each pair of legs. That tells you ...

  c² = a² +b² . . . . . legs a, b; hypotenuse c

__

For the purpose of this problem, it is convenient to consider a slightly different form of the equation.

For legs √a and √b, the hypotenuse √c is given by ...

  (√c)² = (√a)² +(√b)²

  c = a +b

That is ...

  legs √a, √b ⇒ hypotenuse √(a+b)

__

Since the legs are (mostly) given in terms of square roots, the value under the radical for the hypotenuse is simply the sum of those:

legs: √1, √2 ⇒ hypotenuse √(1+2) = √3

legs: √2, √3 ⇒ hypotenuse √(2+3) = √5

legs: √5, √3 ⇒ hypotenuse √(5+3) = √8

legs: √5, √1 ⇒ hypotenuse √(5+1) = √6

_____

Additional comment

You may not see the leg lengths given as square roots very often. This is a rather unusual set of problems for hypotenuse length.

576 ft²

Step-by-step explanation:

Large rectangle:

21·36=756

Smaller rectangle:

15·12=180

Find leftover area:

756-180

=576 ft²

Hope this helps! :)

Answer:

The area that is left for development in the field outside the playground is 576 ft².

Step-by-step explanation:

To calculate the area left for development in the field outside the playground, we need to subtract the area of the smaller rectangle from the area of the larger rectangle.

The area of a rectangle is the product of its width and length:

\(\boxed{\sf Area\;of\;a\;rectangle=width \times length}\)

The dimensions of the larger rectangle are:

The dimensions of the smaller rectangle are:

Therefore, the development area can be calculated as follows:

\(\begin{aligned}\sf Development \;area&=\sf Area_{large\;rectangle}-Area_{small\;rectangle}\\\\&=(21 \times 36)-(15 \times 12)\\\\&=756-180\\\\&=576\; \sf ft^2\end{aligned}\)

Therefore, the area that is left for development in the field outside the playground is 576 ft².

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666...

B) No, supplementary angles are either of two angles whose sum is 180 degrees.

C) Yes, the triangles are congruent because the triangles have exactly the same size and shape

Step-by-step explanation:

B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.

C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.

Answer:

1) . (x-10)^2)=81    2) x=10±9  

Step-by-step explanation:

Got it right on khan

(x-10)² = 81 is the  equation obtained by completing the square and x=10±9 are the solutions to the equation

The given equation is 2x²-20x=x²-19.

We have to rewrite the equation in the form of (x+c)²=d or (x-c)²=d

2x²-20x=x²-19.

2x²-20x-x² = -19

x²-20x+100=100-19

(x-10)² = 81

Take square root on both sides of the equation.

x-10=±√81

x-10=±9

x=10±9

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

Step-by-step explanation:

We are given that the perpendicular bisector of side AB of ∆ABC intersects side BC at point D.

this means that side AE=BE.

Also, we could clear; ly observe that

ΔBED≅ΔAED

( since AE=BE, side ED common, ∠BED=∠AED

so by SAS congruency, the two triangles are congruent)

Now we are given that:

the perimeter of ∆ABC is 12 cm larger than the perimeter of ∆ACD.

i.e. AB+AC+BC=AC+AD+CD+12

AB+BC=AD+CD+12

as AD=BD

this means that AD+CD=BD+CD=BC

AB+BC=BC+12

AB=12

mark as brainliest

The perimeter of 40 cm. and lengths of two sides of ∆ABC where side AC is 10 cm gives;

Given:

AB = BC

AC = 10 cm.

The perimeter of ∆ABC = 40 cm.

Therefore;

∆ABC is an isosceles triangle

AB + BC + AC = 40

AB + AB + 10 = 40 by substitution property of equality

2 × AB = 40 - 10 = 30

AB = BC = 15 cm.

Using the rule of cosines, we have;

cos(A) = (15² + 15² - 10²) ÷ (2×15×15)

<BED ≈ 180° - (90° + 51.06°) = 38.94°

DB = AB ÷ 2

Therefore;

From the rule of sines, we have;

DE = 7.5/sin(38.94°) × sin(51.06°) ≈ 9.28

According to Pythagorean theorem, we have;

Similarly, we have;

EC ≈ 15 - 11.93 = 3.068

Perimeter of ∆AEC = AE + EC + AC

Which gives;

The perimeter of ∆AEC = 11.93 + 3.068 + 10 ≈ 25
