The rate of earning money for both activities will be calculated by dividing the amount earned by the total time spent for each of the activity.

Babysitting: rate = ($30 / 5 hours ) = $6 / hour

Doing chores: rate = ($28 / 4 hours) = $7 / hour

Thus, Holly is able to earn money faster when doing the chores compared to when she do the babysitting if she work for the same amount of time for each.

Answer:

The unit rate for doing chores is $1 more than the unit rate for babysitting.

Step-by-step explanation:

30 divided by 5=6 So that means it was six dollars for babysitting.

28 divided by four=7 So that means it was seven dollars for babysitting.

What is the sign of the product (3) × (−3) × (−2) × (4)?

Free_Kalibri [48]

Answer:

Positive, because the products (3) × (−3) and (−2) × (4) are negative and the product of two negative numbers is positive.

Step-by-step explanation:

Since 1 * -1 = -1, and -1 * -1 = 1, the product of opposite signs produces negative numbers while the product of same signs produces positive numbers. So the product of 1 * 1 * 1 * -1 = -1, while -1 * -1 * -1 * -1 = 1.

Answer:

The mathematical expectation of a student who purchases 10 tickets is -$39.65.

Step-by-step explanation:

A student that purchases 10 tickets out of 2900 has a probability of winning the cruise that can be calculated as:

$p=10/2900\approx0.00345$

Each ticket cost $5, so he has spent $50 for the 10 tickets.

Then, the expected value of this operation is equal to the expected value of the earnings (probability of winning the prize multiplied by the value of the prize), minus the costs:

$E(X)=p\cdot R-C\\\\E(X)=0.00345\cdot3000-50=10.35-50=-39.65$

The mathematical expectation of a student who purchases 10 tickets is -$39.65.
