Answer:
x = 26
y = 9
Step-by-step explanation:
(5x - 17)° + (3x - 11)° = 180° (angles in a straight line)
Solve for x
5x - 17 + 3x - 11 = 180
Collect like terms
5x + 3x - 17 - 11 = 180
8x - 28 = 180
Add 28 to both sides
8x = 180 + 28
8x = 208
Divide both sides by 8
x = 208/8
x = 26
Also:
(2y + 5)° + 90° + (3x - 11)° = 180° (angles on a straight line)
Plug in the value of x and solve for y
2y + 5 + 90 + 3(26) - 11 = 180
2y + 5 + 90 + 78 - 11 = 180
Collect like terms
2y + 162 = 180
Subtract 162 from both sides
2y = 180 - 162
2y = 18
y = 9 (dividing both sides by 2)
The equation for a line is mx + b = y where m is the slope and b is the y intercept. To find the slope, we need to use the equation
.



Therefore, m is equal to -1. Normally, we would then have to plug in m and one of the points to find b. However, because the point (0,5) is the y-intercept (the y-intercept is the point on the line where x is equal to 0), we can skip this step and go straight to forming the final equation, which is
.

Answer:
0.397
Step-by-step explanation:
In the experiment, if the coin is flipped 4 times, the outcomes in which there is a single heads out of the 4 flips are:
HTTT,THTT,TTHT and TTTH
The probability of flipping a head, P(Head)=0.18
Therefore: The probability of flipping a tail, P(Tail)=1-0.18=0.82
We can then calculate the probability that there is a single heads out of the 4 flips
=P(HTTT)+P(THTT)+P(TTHT)+P(TTTH)
=(0.18 X 0.82 X 0.82 X 0.82) + (0.82 X 0.18 X 0.82 X 0.82) + (0.82 X 0.82 X 0.18 X 0.82 )+ (0.82 X 0.82 X 0.82 X 0.18)
