1) Jason flipped a penny many, many times to verify that it lands on heads half the time. He heard that if you apply a layer of

clear coat to the tails side of a penny,it will land on heads more frequently. He decided to test this and coated the tails side of his penny. Jason flipped the coin 200 more times and it landed on heads 54.5% of the time. Do you think his trick worked? Use a 0.05

Answer:

yes theoretically it did work

Step-by-step explanation:

hypothetically it is supposed to land on each side half of the time, but as we all know it's a matter of luck. since after you put on the layer of coating and it landed on heads more thank half of the time (50%), it technically has worked but in a real world application it would be hard to tell/justify.

Use the diagram to find the angle measures of the triangle. Recall that the sum of the angle measures of a triangle is 180 degre
My name is Ann [436]

Answer:

x =29

x+6 =35

4x = 116

Step-by-step explanation:

The sum of the angles of a triangle is 180

x+ (4x) + (x+6) = 180

Combine like terms

6x+6 = 180

Subtract 6 from each side

6x+6-6 = 180-8

6x = 174

Divide each side by 6

6x/6 = 174/6

x =29

x+6 = 29+6 = 35

4x = 29*4 =116

What is the measurement of N?<br> A) 45° <br> B) 90° <br> C) 100° <br> D) 180°
puteri [66]
N would equal 45° since the tiny square means its 90°. 90-45=45.

Answer:
1058.4 in^2

Step-by-step explanation:
Find the surface areas of the rectangular prism and the triangular prisms separately.
Triangular: S = (1/2)lP+B, where l is slant height, P perimeter, and B base area.
14(4)= 56 perimeter of base
13 slant height
B = 14x14 = 196
put together:
S = (1/2)(13 x 56) + 196
S = 560 in^2

Now the rectangular prism
S = 2lw + 2lh + 2wh, where l is length, h height, w width. (delete the first 2lw since they share one side/they're combined shapes.
S = 2(14x8.9) + 2(14x8.9)
S = 498.4 in^2

Add them together: 498.4 + 560 = 1058.4 in^2
