Given is a town has 10,000 two-child families. The town should be divided by smaller units and then conduct a survey on these units to account for the number of two-child families per unit. Combine the number per unit and divide by the total population of the town. Construct a table containing the name of the units and the number of two-child family per unit.

Correct answer


The simulation tool could be a coin flip, with heads up representing a girl and tails up representing a boy. One trial would require flipping the coin twice. One table would show the outcome of two coin tosses as tally marks, and indicate whether the results were boy-boy, boy-girl, or girl-girl.

Of 360 consumers polled some purchased ice cream some purchase frozen yogurt and some purchased both if 260 people polled purcha
Xelga [282]

Total customers are = 360

Number of polled people who purchased ice cream = 260

Number of polled people who purchased both ice cream and yogurt = 250

Hence, people who purchased only ice cream are=260-250=10

And 360-10=350 are people who purchased yogurt.

So, people who purchased yogurt only = 360-(250+10)=100

maria and her sister each have a salad and a drink for lunch at a restaurant. a salad costs $4.75 and a drink costs $1.65. what
oksano4ka [1.4K]
The salads in total are $9.50
The waters in total are $3.30

together the total cost is $12.80

First, convert the 15% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 15%) by 100%. So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $12.80 meal cost is. This is always done by multiplying 0.15 by $12.80, or

0.15 x $12.80=$1.92.

So, the amount of tip you are going to leave is $1.92.

This makes the total cost of your meal (to write on your charge slip or other payment)

<span>$12.80 + $1.92 = $14.72.</span>

A parcel has a mass of 500g. Calculate its weight. (Assume the gravitational field strength is 10N/kg).
Elan Coil [88]

Answer:

The weight of the parcel is 5 N

Step-by-step explanation:

we know that

Weight can be calculated using the equation:

 W=mg

where

W ----> weight (W) is measured in newtons (N)

m ----> mass (m) is measured in kilograms (kg)

g ----> gravitational field strength (g) is measured in newtons per kilogram (N/kg)

In this problem we have

g=10\ N/kg

m=500\ g

Remember that

1\ kg=1,000\ g

To convert g to kg

Divide by 1,000

so

m=500\ g=500/1,000=0.5\ kg

substitute the values in the equation

W=(0.5)(10)=5\ N

therefore

The weight of the parcel is 5 N
