Answer:
Step-by-step explanation:
A goblet contains 3 red balls, 2 green balls and 6 blue balls.
Total balls = 3 + 2 + 6 = 11 balls
we choose a ball and then another ball without putting the first one back.
The probability that the first ball will be red = =
Second event is done without replacing the first ball so total ball will be 10
The probability that the second ball will be blue = =
=
P = ×
=
The probability that the first ball will be red and the second ball will be blue is
<em><u>Solution:</u></em>
Given that,
Actual volume of his bathtub is 37 gal
Estimate is 31 gal
<em><u>Find the absolute error</u></em>
Absolute Error = | Measured Value - Actual Value |
Absolute Error = | 31 - 37 |
Absolute Error = 6
<em><u>Find the percent error</u></em>
Substituting we get,
Negative sign means percent decrease
Thus percent error is 16.22 %
Answer:
The density of oak is <u>0.695</u> grams per cubic centimeter.
Step-by-step explanation:
Given:
Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.
Now, to find the density of oak in grams per cubic centimeter.
Mass (m) = 2.85 kilograms.
So, using conversion factor we convert into grams:
Volume (v) = 4100 cubic centimeters.
Now, to get the density by using formula:
Therefore, the density of oak is 0.695 in grams per cubic centimeter.
Step-by-step explanation:
It is given that, a mouse covered a distance of 3/24 miles over a distance of 3 hours. Each hour, the mouse traveled the same distance. Distance traveled in 1 hour can be calculated by dividing 3/24 miles by 3. So,
Matt calculations shows that the distance is 3/8 hours. While dividing 3/24 by 3, he doesn't take reciprocal of 3 as a result he get 9 on numerator and 24 on denominator. Simplified fraction of 9/24 is 3/8. But the correct answer should be 1/24 hours.
