Answer:
The probability is 3.125%
Step-by-step explanation:
From the question, we are told that the probability that it rains on a particular day is 50% = 50/100 = 1/2
So the probability that it rains for the 5 days continuously will be ;
1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/32 = 0.03125
which is 3.125%
The group with need to fill the spoon a total of 3 times this is because 1/8+1/8+1/8=3/8
Answer:
<h3>Question 1</h3>
<u>Function given:</u>
<u>In the vertex form:</u>
- y = x² + 4x + 4 - 8 = (x + 2)² - 8
Axis of symmetry is the vertical line passing through the vertex.
<u>The vertex is</u>
<u>Axis of symmetry is </u>
<u>y- intercept is </u>
- x = 0 ⇒ y = -4, so the point (0, -4)
<u>Two other points are</u>
- x = 1 ⇒ y = (1 + 2)² - 8 = 9 - 8 = 1, the point is (1, 1)
- x = -1 ⇒ y = (-1 + 2)² - 8 = 1 - 8 = -7, the point is (-1, -7)
<em>See the graph with all the points plotted</em>
<h3>Question 2</h3>
<u>Function given:</u>
<u>In standard form:</u>
<u>In vertex form:</u>
- y = - 2x² + 4x - 2 + 8 = -2(x - 1)² + 8
<u>The vertex:</u>
<u>Axis of symmetry is </u>
<u>y - intercept </u>
- x = 0 ⇒ y = -2(-1)² + 8 = -2 + 8 = 6, the point is (0, 6)
<u>Two other pints:</u>
- x = -1 ⇒ y = -2(-1 - 1)² + 8 = -8 + 8 = 0, the point is (-1, 0)
- x = 2 ⇒ y = -2(2 - 1)² + 8 = -2 + 8 = 6, the point is (2, 6)
<em>The graph is attached with the points plotted.</em>
This can be solve using trigonometric function. since the
given side is the adjecent of the angle which is length of the shadow and the
unknown is the side opposite the angle, which is the height of chad.
Tan (a) = opposite / adjacent
Opposite = tan(23) * 14.3 ft
Opposite = 6.1 ft is the hieght of Chad
Can you re right this so I can actually understand it
