Answer:

7.4 m/ $s^{2}$ .

Step-by-step explanation:

When an object rotates around a fixed center in a circular path of radius R then centripetal force acts on the object ,

Centripetal acceleration equals

$\frac{v^{2} }{r}$ Where,

v is the velocity of the object rotating in circular motion

and r is the radius of the circle.

Here , r = 65 meters.

v = 22 m/s.

Thus centripetal acceleration equals $\frac{22^{2} }{65}$

= 7.44 m/ $s^{2}$ .

Thus option A is the best option i.e., 7.4 m/ $s^{2}$ .

Assume the resting heart rates for a sample of individuals are normally distributed with a mean of 75 and a standard deviation o

Shalnov [3]

Answer:

a) 0.975

b) 0.16

c) 0.475

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 75

Standard deviation = 5

We also have that since the normal distribution is symmetric, 50% of the measures are below the mean and 50% are above.

a. The relative frequency of rates less than 85 using the 68-95-99.7 rule is

85 is two standard deviations above the mean.

So all the 50% below the mean is below 85

And of the 50% above the mean, 95% is less than 85. So

0.5 + 0.95*0.5 = 0.975

b. The relative frequency of rates greater than 80 using the 68-95-99.7 rule is

80 is one standard deviations above the mean.

Of the 50% above the mean, 68% is less than 80. So 100-68 = 32% is more than 80.

0.32*0.5 = 0.16.

c. The relative frequency of rates between 65 and 75 using the 68-95-99.7 rule is

Within the mean and two standard deviations below the mean.

So 95% of 50%

0.95*0.5 = 0.475

Mrs. Smith needed to split 28 students into 4 equal groups for the race. Which step could help her to work 30 divided by 3?

Anastaziya [24]

Answer:

Procedure in option C only works.

Step-by-step explanation:

We have to select the process in which Mrs. Smith can help her to work 30 divided by 3.

(A) (27 divided by 9) + (9 divided by 3) = 3 + 3 = 6

But (30 ÷ 3) = 10 ≠ 6

(B) (24 divided by 4) + (4 divided by 4) = 6 + 1 = 7 ≠ 10

(C) (21 divided by 3) + (9 divided by 3) = 7 + 3 = 10

(D) (20 divided by 4) + (10 divided by 4) = 5 + 2.5 = 7.5 ≠ 10

So, procedure in option C only works. (Answer)

Again, we can prove the procedure in the following way:

$\frac{30}{3} = \frac{21 + 9}{3} = \frac{21}{3} + \frac{9}{3}$

{Which is the distributive property of division}
