The marketing department of a nationally known cereal maker plans to conduct a national survey to find out whether or not consum

ers of flake cereals can distinguish one of their favorite flake cereals. In the survey, eight people were presented with five bowls of flake cereal, and were told that only one contained their favorite. Suppose that the eight persons in the experiment were unable to identify their favorite cereal and just guessed which bowl it was in. What is the probability that none of the eight guessed correctly

Answer:

Step-by-step explanation:

The probability that a person answered incorrectly is 4/5

P(1st answered incorrectly AND 2nd answered incorrectly AND

3rd answered incorrectly AND 4th answered incorrectly AND

5th answered incorrectly AND 6th answered incorrectly AND

7th answered incorrectly AND 8th answered incorrectly)

Since "AND" mean to multiply, the probability that none of the 8 guessed correctly is

4/5×4/5×4/5×4/5×4/5×4/5×4/5×4/5

=(4/5)^8

=0.16777216

At 1:00 pm the water level in a pool is 13 inches. At 1:30pm the water level is 18 inches. At 2:30pm the water level is 28 inche
SashulF [63]
From the given question we come to know of certain number of facts and they are:
At 1:00 PM the water level of the pond was = 13 inches
At 1:30 PM the water level of the pond was = 18 inches
At 2:30 PM the water level of the pond was = 28 inches
From the above given facts we can easily find the amount of water changing every half an hour.
Amount of increase in water from 1:00PM to 1:30 PM = (18 - 13) inches
                                                                                       = 5 inches
Amount of increase in water level from 1:30PM to 2:30PM = (28 -18) inches
                                                                                             = 10 inches
From the above two deductions we can come to the conclusion the the constant rate of change in water level is 5 inches for every half an hour.

The slope-intercept form of the equation of a line that passes through point (-2, -13) is y = 54 -3. What is the point slope
dangina [55]

Answer:

y+13=5(x+2)

Step-by-step explanation:

<u><em>The correct question is</em></u>

The slope-intercept form of the equation of a line that passes through point (-2, -13) is y = 5x -3. What is the point slope  form of the equation for this line?

we have

y=5x-3

This is the equation of the line in slope intercept form

where

the slope is m=5

the y-intercept is b=-3

Remember that

The equation of the line in point-slope form is equal to

y-y1=m(x-x1)

we have

m=5

point\ (-2,-13)

substitute

y-(-13)=5(x-(-2))

y+13=5(x+2)

(HELPPPPPPP) ples help me with 1, 2, 3
ra1l [238]

Answer:

Okay so number 3 is either undefined or Zero. I always forget which is which.

Step-by-step explanation:

But for 1 and 2 use your solution m=rise/run. Or you could count the ways down, like say, for number 1 it runs over 3 from a point and goes up till the next point. I hope this helps.
