20 mins means the hand moves 120 degrees around the clock.

The formula to find the arc length is 2pi×r×a/360

2×pi×15×1/3=30pi×1/3=10pi

so i think the answer would be 10 pi cm

Question 1.1. Suppose a normal distribution has a mean of 20 and a standard deviation of 4.
Nookie1986 [14]
Answer: Question 1.1: It is 1.5 standard deviations away from the mean.

Our value of 26 is 6 units about the mean of 20. If each standard deviation is 4, we just divide 6 by 4. This gives us the number of standard deviations.

Question 2.2 The correct answer is -0.52

If we are 0.52 standard deviations below the mean, then our z-score is simply -0.52. The definition of a z-score is the number of standard deviations from the mean.

the width of a rectangle is 7 meters greater than its length.If the area of the rectangle is 170 square meters, write the quadra
Anika [276]

Answer:

x^2+7x-170 = 0

Step-by-step explanation:

To calculate an area of a rectangle, use the formula A=l*w. We know the width is 7m greater than the length. So w = 7 + x. So the area is A= (7+x)*x.

We also know the area is 170. Substitute this value for A and solve.

170 = (7+x)(x)\\170 = 7x+x^2\\x^2+7x-170 = 0
