Step-by-step explanation:
in two months
Decrease of 25%
so you need to do
25%*12 is 3 minutes
Find the difference from 12 minutes
12-3 is 9 minutes.
therefore, his mile time is 9 minutes in two months
Step-by-step explanation:
Step 1
Subtract the mean from your score. For example, if you scored 33 and the mean is 24, you would get a difference of 9.
Step 2
Divide the difference found in Step 1 by the standard deviation of the data to find the z-score, which is the number of standard deviations away from the mean that your score is. For example, if the standard deviation was 4.5, you would have a z-score of 2.
Step 3
Convert the z-score to a percentile using a z-score chart or converter available online (see Resources section). When converting, be sure to use a one-sided test. For example, a z-score of 2 would be in the 98th percentile.
Answer:
<h3> the area of the triangle is 9cm²</h3>
Step-by-step explanation:
<u>Question in English</u>
The base of the KOS triangle is 6 cm, and the height lowered on this base is half of it. Calculate the area of the KOS triangle and draw another triangle with the same field. Quick, please!
Given that:
The base is 6 cm
height is half of the base, 6 / 2 = 3cm
Area of a triangle is
<h3>Therefore, the area of the triangle is 9cm²</h3>
5(3x)+4=-10 i think that is the correct answer
