Answer:

AB=5.6

Step-by-step explanation:

Answer:

AB ≈ 5.6 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos62° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{12}[/tex] ( multiply both sides by 12 )

12 × cos62° = AB , then

AB ≈ 5.6 cm ( to 1 dec. place )

Answer:

x = 76°

y = 128°

z = 16°

Step-by-step explanation:

JKLM is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

x + 104° = 180°

x = 180° - 104°

[tex] \huge \red {\boxed {x = 76\degree}} [/tex]

y + 52° = 180°

y = 180° - 52°

[tex] \huge \purple {\boxed {y = 128\degree}} [/tex]

By inscribed angle theorem:

[tex] 88\degree + z = 2\times 52\degree \\\\

88\degree + z = 104\degree \\\\

z = 104\degree - 88\degree \\\\

\huge \orange {\boxed {z = 16\degree}} [/tex]

Answer:

Step-by-step explanation:

From the given information:

Let X represent the amount of the stock that goes up in the first period; &

Let Y denote the cumulative amount that goes up in the first three periods.

Then,

[tex]X= X_1 + X_2 \\ \\ \\EX= EX_1 +EX_2\\ \\\\Now ; EX = 0 \\ \\ EX = \dfrac{1}{2}\times 1 + \dfrac{1}{2}\times -1 \\ \\ EX = \dfrac{1}{2}-\dfrac{1}{2} \\ \\ EX = 0[/tex]

[tex]Cov(x,y) = Var(X_1) +Var(X_2) \\ \\ =\dfrac{1}{2}(1+1) + \dfrac{1}{2}(1+1) \\ \\ = \dfrac{1}{2}(2)+ \dfrac{1}{2}(2) \\ \\ = 1+1 \\ \\ =2[/tex]

[tex]Var (X) = Var (X_1+X_2)\\ \\ = 2 \ Var(X_1) \\ \\ = 2 \times (1) \\ \\ = 2[/tex]

[tex]Var (Y) = Var (X_1 +X_2+X_3) \\ \\ = 3 \times Var(X_1) = \\ \\ = 3 \times 1\\ \\ = 3[/tex]

∴

[tex]Corr(x,y) = \dfrac{2}{\sqrt{6}} \\ \\ = \dfrac{2}{\sqrt{2\times 3}} \\ \\= \sqrt{\dfrac{2}{3}}[/tex]

Step-by-step explanation:

Answer:

The term rule will be:

[tex]a_n=n+21[/tex]

Step-by-step explanation:

Given the sequence

[tex]22, 23, 24, 25, ...[/tex]

Computing the common difference of all the adjacent terms

[tex]22,\:23,\:24,\:25[/tex]

[tex]23-22=1,\:\quad \:24-23=1,\:\quad \:25-24=1[/tex]

As the difference between all the adjacent terms is the same and equal to

[tex]d=1[/tex]

The first element of the sequence

[tex]a_1=22[/tex]

We know that  An Arithmetic sequence has a constant difference 'd' and is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting [tex]a_1=22[/tex], and [tex]d=1[/tex] in the nth term to get the term rule

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=\left(n-1\right)+22[/tex]

[tex]a_n=n+21[/tex]

Therefore, the term rule will be:

[tex]a_n=n+21[/tex]

Answer:

Step-by-step explanation:

okay so to get 10% of 20 you just move the decimal to the right one so 25.0 would become 2.5 then to find 20% of that you multiply by 2 so 2.5 x 2 = 5 so that means the team lost 5 girls. 25-5=20 therefor there are 20 players on the team this year

Answer:

Her proportion does not have corresponding parts in the same position.

Step-by-step explanation:

Sharon is drawing up a plan for building a reduced Eiffel Tower on her backyard patio. She has room to make a base of 5 feet. Her work is shown below.

What was Sharon’s error in finding the missing height measurement for her reduced tower?

Her proportion does not have corresponding parts in the same position.

For cross products, she needed to multiply 1050(328) and 5(x).

She needed to divide both sides by 1640, instead of 1050.

She needed to round down to 1.5 feet.

Height : base = 1,050 : 328

She has room to make a base of 5 feet.

Height : base = x : 5

1,050 : 328 = x : 5

1,050 / 328 = x / 5

Cross product

1,050 * 5 = 328 * x

5,250 = 328x

Divide both sides by 328

x = 5250 / 328

= 16.006

Approximately 16

Answer:

The answer is "Through which we can infer that perhaps the ABC triangles is obstinate shaped".

Step-by-step explanation:

Paul draws that ABC as well as the Median triangle from and A and B nodes. If the median passes after a certain point, and his marks the point X. Paul now says point X (i.e., a triangle's center) is outside the ABC triangle.  

They may also conclude that perhaps the ABC triangle does have an obtuse angle because the centroid is in the ring in case of even a severe triangle, that centroid is already on the right triangle in case of the triangle and cases of an obtuse-angled rectangle, the angular velocity is an outside ring.

Answer:

y = -2x + 4

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of a line passing through (0, 4) and (2, 0) will be,

m = [tex]\frac{4-0}{0-2}[/tex]

   = -2

Y-intercept of the line 'b' = 4

Therefore, equation of the line will be,

y = -2x + 4

Answer:

8b+7p=20

p = 2b

Step-by-step explanation:

Given that there is a constant speed of 8 km per hour and the number of hours be b so here 8b signifies the distance

Now on the other hand there is a constant speed of 7 km per hour and the number of hours be p so here 7p signfies the distance

So the total distance would be

= 8b + 7p

And, the total km is 20

Now the whole equation would be

8b + 7p = 20

Also it is mentoined that for getting into the park it is twice for getting into the beach

So, it would be

p = 2b

Therefore the system of equations are as follows

8b+7p=20

p = 2b
