Answer:
Here's how to solve it.
Step-by-step explanation:
Ok so, a negative integer and positive ALWAYS equals a negative.
Negative and negative equals positive because it cancels out.
Positive and Positive equals positive.
So to answer your question What negative number times by a positive equals -10?
Well 5 * 2 = 10 Right?
So -5 * 2 = -10
Hope this Helps.
1. As you can see in the graph attached, the x axis represents the time in seconds and the y axis represents the height in meters.
2. Therefore, to solve this exercise and calculate <span>how many seconds is the nail 50 m above the ground, you must draw a segment from 50 meters to the curve and then, you need to draw another segment from that point at the curve, to the x axis, as it is shown in the figure attached.
3. You can conclude that </span>the nail is 50 meters above the ground<span> in 3.9 seconds.
Therefore, the answer is: 3.9 s</span>
<u>Answer-</u>
<em>In </em><em>25.15%</em><em> cases their response times is over 30 minutes.</em>
<u>Solution-</u>
Hint- Calculating the z-score (how much standard deviations away from the mean) and then getting the corresponding probability value from normal distribution table we can get solution.
Applying the formula for Z-score,
Here,
X = score = 30,
μ = mean = 22,
σ = standard deviation = 11.9
Putting the values,
(Subtracted from 1 as the values of area to the left of the Z score is given in table, but we need the area right to Z score as response times more than 30 minutes is asked)
C
In order to calculate the new vertices, we simply add 1 to the value of x in each point since the translation is towards the positive x-axis and subtract 3 from the y values of each point since the translation is towards the negative y-axis.
