Earth has a mass of 5.97 × 1024 kg and Venus has a mass of 4.87 × 1024 kg. How much more mass does Earth have than Venus? Earth
dezoksy [38]

Answer:

The answer to your question is a = 1.1; b = 24

Step-by-step explanation:

Data

Earth's mass = 5.97 x 10²⁴ kg

Venus' mass = 4.87 x 10²⁴ kg

Process

1.- Subtract the Venus' mass to the earth's mass.

                    5.97

                 <u> -  4.87</u>

                     1.1

2.- Write the result in scientific notation

                      1.1 x 10²⁴ kg

3.- Result

a = 1.1

b = 24

Given a standardized normal distribution (with a mean of O and a standard deviation of 1), determine the following probabilities
Mkey [24]

Answer:

a) P(Z > 1.09) = 0.1379

b) P(Z < -0.22) = 0.4129.

c) P(Z < -1.96) = 0.025, P(Z > -1.96) = 0.025

d) Z = 1.4

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

a. P(Z > 1.09)

This is 1 subtracted by the pvalue of Z = 1.09.

Z = 1.09 has a pvalue of 0.8621

1 - 0.8621 = 0.1379, so

P(Z > 1.09) = 0.1379

b. P(Z < -0.22)

This is the pvalue of Z = -0.22.

Z = -0.22 has a pvalue of 0.4129. So

P(Z < -0.22) = 0.4129.

c) P(Z < -1.96) or P(Z > -1.96)

Z = -1.96 has a pvalue of 0.025. So

1 - 0.025 = 0.975

P(Z < -1.96) = 0.025

P(Z > -1.96) = 0.025

d. What is the value of Z if only 8.08% of all possible Z-values are larger?

Z with a pvalue of 100 - 8.08 = 91.92 = 0.9192, so Z = 1.4

Pauline withdrew $7.50 from her savings account every day for 3 days. Which expression is the best choice to help her determine
artcher [175]

Answer:

\$(-7.50)(3\ days)= - 22.50

Step-by-step explanation:

Given: Pauline withdrew $7.50 each day from her saving account.

          She withdrew money for 3 days.

As Pauline is withdrawing the money, therefore the amount will be in negative

Now finding the expression for total amount of money withdrew.

Total money withdrew = (Money\ withdrew\ each\ day)\times (number\ of\ day)

∴ Total money withdrew = \$ -7.50\times 3\ days= - 22.50

Hence, the expression to determine the total amount of money she withdrew is (-7.50)(3)= -22.5 and Total money she withdrew is -$22.5
