Three fair quarters are tossed, and a tail appears on at least one of them. What is the probability that at least one head appea

nirvana33 [79]

Answer:

Probability that at least one head appears is $\frac{6}{7}$

Step-by-step explanation:

Given : Three fair quarters are tossed, and a tail appears on at least one of them.

To find : What is the probability that at least one head appears?

Solution :

When three fair quarters are tossed the sample form is

$\{HHH,HHT,HTH,HTT,THH,THT,TTH,TTT\}$

According to question,

In a sample space a tail appears on at least one of them.

i.e. Total outcomes is $\{HHT,HTH,HTT,THH,THT,TTH,TTT\}=7$

Favorable outcome is getting at least one head appears

i.e. Favorable outcome is $\{HHT,HTH,HTT,THH,THT,TTH\}=6$

Probability that at least one head appears is

$\text{Probability}=\frac{\text{Favorable outcome }}{\text{Total outcome}}$

$\text{Probability}=\frac{6}{7}$

Therefore, Probability that at least one head appears is $\frac{6}{7}$

A group of robins took 78 days to fly 3000 miles. On average about how many miles did the robins flight each day? Explain why yo

Irina-Kira [14]

Answer:

$34.48\text{ miles}$

Step-by-step explanation:

GIVEN: A group of robins took $78$ days to fly $3000$ miles.

TO FIND: On average about how many miles did the robins flight each day.

SOLUTION:

Total number of days taken by robins to fly the distance $=78$

Total distance traveled by robins $=3000\text{ miles}$

Now,

Average miles robins flights each day $=\frac{\text{total miles traveled by robin}}{\text{total days taken}}$

$=\frac{3000}{78}$

$=34.48$

Hence robin flight average $34.48$ miles each day.

What are the coordinates of N?

Nataliya [291]

Answer:

$(c,b) are the coordinates of N$

Step-by-step explanation:

as N is the mid-point of QR

BY USING MID-POINT FORMULA

$N(x,y)=(\frac{x1+x2}{2},\frac{y1+y2}{2})$

PUTTING THE VALUES OF COORDINATES

$N(x,y)=(\frac{0+2c}{2},\frac{2b+0}{2})$

$N(x,y)=(\frac{2c}{2},\frac{2b}{2})$

$N(x,y)=(c,b) are the coordinates$
