A child bounces a 48 g superball on the sidewalk. The velocity change of the super bowl is from 23 m/s downward to 14 m/s upward
mestny [16]

Answer:

F_{a} = 0.0009866 N

Step-by-step explanation:

For resolving this problem we can use the impulse-momentum theorem; this theorem establishes that  the change in momentum of an object equals the impulse applied to it

The impulse is defined how:

I = F_{a}Δt

    F_{a}:   Average force

    Δt =  Time interval

Then:

mv_{f}-mv{o} = F{a}Δt

(0.048)(14) - (0.048)(-23) = F_{a}(1800)

0.672 + 1.104 = F_{a}1800

1.776 = F_{a}1800

F_{a} = \frac{1.776}{1800}

F_{a} = 0.0009866 N

A soft drink machine outputs a mean of 2323 ounces per cup. The machine's output is normally distributed with a standard deviati
viktelen [127]

Answer:

Area under the normal curve: 0.6915.

69.15% probability of putting less than 24 ounces in a cup.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 23, \sigma = 2

You have been asked to calculate the probability of putting less than 24 ounces in a cup.

pvalue of Z when X = 24. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{24 - 23}{2}

Z = 0.5

Z = 0.5 has a pvalue of 0.6915

Area under the normal curve: 0.6915.

69.15% probability of putting less than 24 ounces in a cup.
