Answer:
probability of getting no heads: 1/ 8
probability of at least two tails: 1/4
Step-by-step explanation:
To calculate the probability of getting no heads, multiply the probability of not getting heads for each coin. A coin has two sides: heads and tails; the probability of not getting heads would be 1/2.
1. Multiply the probabilities for each coin
1/2 · 1/2 · 1/2 = 1/8
To calculate the probability of getting at least two tails, multiply the probability of getting tails for two coins and the probability of flipping either heads or tails for the remaining coin. Because it is at least two tails, the remaining coin can flip to either heads or tails.
1. Multiply the probabilities for each coin
1/2 · 1/2 · 2/2 = 1/4
Answer:
Actual area = 21600 Sq.miles
Step-by-step explanation:
We are given;
length; L = 4 inches
Width; W = 6 inches
The scale of the map; 1 inch for every 30 miles i.e. 1 : 30
Since the scale is 1:30, let's find the find the actual dimensions and then the actual area
For the Length,
Since 1 inch represents 30 miles,
Then, 4 inches = (4 × 30)/1 = 120 miles
For the width;
Since 1 inch represents 30 miles,
Then,6 inches = (6 × 30)/1 = 180 miles
Therefore, the actual dimensions are 120 miles and 180 miles
Now, formula for area of rectangle = length × width
Thus;
Actual area = 120 × 180
Actual area = 21600 Sq.miles
Answer:
67.6
Step-by-step explanation:
first, to find the mean you add up all the numbers and you would get 338. Next, you divide by how many numbers there are (5) so 338 divided by 5 equals 67.6
Answer:
63‾√2
Step-by-step explanation:
Answer:
Step-by-step explanation:
For this equation you want to start with signing the equation for the best line of fit. You’re going to take your year in and your rabbitsFrom the table and you’re going to find the slope in the Y intercept which would be your MX and you’re B. If you used as most you want to pull up a table in the graphing calculator and into your data there when you get there and the next box under your table you’re going to put y1~mx1+b There it will show you your slope and your intercept along with other things you will need to know for the equation when you get here sleeping when you said you’re going to round to the second decimal place and then you should get y=8.2x-16451.3 Which will be your best line of fit. Now when you’re trying to estimate the number rabbit at the farm In 2016 you want to put your year where X is so you’ll input your 2016 where x is and you should get 8.2(2016)-16451.3From there you solve it and you’re around to the second decimal space and there you have your just wanna sit and your estimate
