It is 10% higher than the theoretical probability.Thats the answer because the theoretical odds are 50-50% (75 heads and 75 tails). 10% of 75 is 15, so 75+15=90, which means that it got a 10% higher than the theoretical probability.

Answer:

Step-by-step explanation:

4x-2y=3

Get into y=mx+b

-4x on each side

Then divide by -2

y=2x- 1.5

Now if a line is parallel to another line the slope will be the same. If perpendicular the slope will be the negative reciprocal. As you said it is parallel the slope is 2.

y = mx+b

y = (slope)x + y-intercept

y= 2x + 1

Sorry if it is wrong but I hope it is right

Answer:

Step-by-step explanation:

These are logically difficult, so it makes sense to me you're asking about this.

so A = 1/2 (big arc - small arc)

and 360 = big arc + small arc

then

360 - small arc = big arc

so rewrite the top equation

A = 1/2(360-small arc -small arc)

63 = 1/2( 360 - 2 small arc)

2* 63 = 360 - 2 small arc

126 = 360 - 2 small arc

2 small arc = 360-126

2small arc = 234

small arc = 234/2

small arc = 117

x = 117°

Answer:

RQ = 49

Step-by-step explanation:

12/28 = 21/RQ (Ratio of sides of similar triangles are equal)

12 x RQ = 21 x 28

RQ = 588 / 12

RQ = 49
