Answer:
0.167772
Step-by-step explanation:
Given that eight persons were asked to cooperate in an experiment. Five very small bowls of flake cereals were placed in front of a person
Since each one makes only guess probability for correct guess is
=
Each person is independent of the other
Hence X no of persons out of eight persons selected to guess correctly is binomial with n =8 and p = 0.2
Required probability
=the probability that none of the eight guessed correctly
=
Answer:
<em>The freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.</em>
Step-by-step explanation:
The model for the freezing point of water T at altitude a is:
T(a)= 0.0001a+32
The slope of this equation is the coefficient of the variable a. Since the slope is positive, it means the freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.
For example, when a=1000, the freezing point is:
T(1000)= 0.0001*1000+32 = 32.1°F
When a=1001, the freezing point is:
T(1001)= 0.0001*1001+32 = 32.1001°F
Note the increase of 1 foot in altitued meant an increase of 32.1001-32.1 = 0.0001°F
Answer: Angle 1 is 36
Angle 2 is 54
Step-by-step explanation:
x+18+3x=90
4x+18=90
4x=72
x=18
18+18=36
18*3=54
Answer:
Angle 3= 37 degrees, Angle 2 = 143 degrees, Angle 4= 143 degrees
Step-by-step explanation:
Angle 3 is across from Angle 1 so they are equal to each other. Now to find Angles 2 and 4, cover angles 2 and 3 with your hand so you are just looking at 1 and 4, they are on a line. Lines are 180 degrees, so since angle 1 we know is 37 degrees, then 180-37= 143 degrees for angle 4. Now, 2 and 4 are opposites of each other, and share the same value of 143 (just like how we found angles 1 and 3 to be equal bc they are across from each other)
