URGENT Question HELP FAST!!!!!

Answer:

Part A

Part B

Step-by-step explanation:

Given data:

Find the mean of the data above:

Find absolute deviations, an absolute value of the difference of data and the mean:

Find mean absolute deviation:

Correct choice is C

Less mean absolute deviation is the sign of more consistent data.

Since Ryan Shafer has smaller mean absolute deviation, he has been more consistent 7 < 7.25

Correct choice is B.

Answer:

a) 16 meters ; b) 8 seconds

Step-by-step explanation:

The function can be represent with a parabola whose vertex is its maximum point

for answer the first question we have to find the y of the vertex

first of all we have to find the x

Vertex (x) = -b/2a = -8/-2 = 4

if we substitute t with 4, we can find the y

Vertex (y) = -(4^2) + (8*4) =

= -16 + 32 = 16

so the answer is 16 meters

for answer the second question we have to find where the parabola intercepts the x axis, that means solve the associated equation:

-t^2 + 8t = 0

t^2-8t = 0

t(t-8) = 0

t = 0

t = 8

the parabola intercept the x axis in (0,0) and in (8,0)

if we find the distance between this two points we can answer to the question

8-0 = 8 seconds

Answer:

right and scalene

Step-by-step explanation:

all the sides are different in length, so it's a scalene triangle, plus, it has a right angle, which makes it a right angled triangle.

Step-by-step explanation:

tan3 = 200/x

x = 200/tan3

The question is incomplete. The right question is:

A ranger spots a fire while on a 200-foot observation tower. The angle of depression from the tower to the fire is 3°. To the nearest tenth of a foot, how far away is the fire from the base of the tower?​

The distance between the fire and the base of the tower is 3816.2 feet.

Heights and Distances is a trigonometric application-based concept, where we try to form a right-angled triangle of the given conditions, take the angles of elevation and depression and try to find the unknowns.

We are given that a ranger spots a fire while on a 200-foot observation tower. The angle of depression from the tower to the fire is 3°.

We are asked to find the distance between the fire and the base of the tower.

We let the 200-foot observation tower be AB. Let the point of fire be C. Join BC and AC to complete the right-angled triangle ABC, with ∠B = 90°. The ranger from the top of the tower has a 3° angle of depression to the fire. We draw the horizontal line of sight AD. Now the angle of depression can be shown by the ∠DAC = 3°.

We let the distance between the fire and the foot of the tower be x foot.

∠BCA = ∠DAC = 3° (alternate angles).

Also, ∠BAC = 180° - 90° - 3° = 87° (using angle sum property of triangles)

In ΔABC,

tan ∠BAC = BC/AB (tan θ = perpendicular/base)

or, tan 87° = x/200

or, x = 200*tan87° = 200*19.0811 = 3816.22 = 3816.2 (rounding to nearest tenth).

∴ The distance between the fire and the base of the tower is 3816.2 feet.

Answer:3/2

Step-by-step explanation:

Answer:

Dave and Anna:

1. Income highlight:

combined take home pay of $900/week

Total income: 4(900) - because 4 weeks in most months = $3600

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

2. Expense highlights:

bi-weekly mortgage of $675

property taxes of $1800

Car expenses $160

Car insurance: $128

House insurance: $35

Saving for kids: $200

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

Expense calculations:

Mortgage bi-weekly = 675 x 2 = $1350/month

Property taxes = 1800/12 months/year = 150/month

everything else is already monthly

1350 + 150 + 160 + 128 + 35 + 200 = 2,023

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

income - expenses

$3600 - 2023 = $1,577 surplus

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

Jacob:

Income highlights:

Canada Pension Plan $848/month

Old Age Security: $484/month

Total income: $1332

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

Expense highlights:

property tax: $3000/yr = $250/month

burial expenses: $100/month (for 6 more months)

golfing: $500/year = $41.67/month

bowling: $100/year = $8.33/month

Total expenses: 250 + 100 + 41.67 + 8.33 = 400

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

Income - expenses:

1332 - 400 = $932 surplus

Answer:

x = 12    y = 24     z = 12[tex]\sqrt{3}[/tex]

Step-by-step explanation:

you are correct.  x = 12

The dotted line has a length of 12 also

The dotted line is the shorter leg of the 30-60-90 triangle.

So, z = 12[tex]\sqrt{3}[/tex] and y = 24

Answer:

62 degrees

Step-by-step explanation:

HJ is a line which means its 180 degrees if HIL is 118 degrees then LIJ is 62 degrees and due to the lines being parallel then MLN is also 62 degrees

So, we know that ∠HIL = 118, and we also know that a line is 180 degrees. This means that ∠HIL +∠JIL = 180. We can use simple arithmetic and substitution to find that 180-118= 62, so ∠JIL = 62.

We have another line, Line N, so we know that the line is equal to 180 as well! Because ∠JIL and ∠ILM are both on this line, ∠JIL +∠ILM = 180. ∠JIL = 62, so 180 - 62 = 118.

Lastly, Line N is still equal to 180, so ∠ILM + ∠MLN = 180. In this case, we have 180-118=62, so ∠MLN = 62.

Or, using theorems, there is an easier way to do this.

The corresponding angles theorem tells us that "If a transversal intersects two parallel lines, the corresponding angles are congruent." So, we can see that both ∠MLN and ∠JIL are corresponding so they are congruent. First, however, we need to find ∠JIL, and if we look at our work from above, we see that ∠JIL = 62. Since ∠JIL and ∠MLN are congruent, or the same, ∠MLN is also 62.

✧ We know , Reflection of a point on x - axis remains the x - co-ordinate same but the sign of y - coordinate changes i.e P ( x , y ) ⇢ P' ( x , - y ). So, the image of the point ( 8 , 10 ) under the reflection on x - axis is :

A ( 8 , 10 ) ⇢A' ( 8 , -10 )
