The sum of 3 consecutive integers is 18. What is the greatest of these integers
VashaNatasha [74]

Answer:

5+6+7=18, so the greatest of these integers is 7.

Step-by-step explanation:

Consecutive integers are numbers that come one right after the other, in chronological order, so by figuring out which numbers add up to 18 that go in chronological order, you will be able to find your greatest integer.

Please answer quickly will give brainliest to correct answer
Mkey [24]

Answer:

a.   π(9^2)(9) - (1/3)(9^2)(9)

step-by-step explanation:

we assume that container a is the whole cylinder, and that container b is the cylinder with the cone carved out.

the formula for the volume of a cylinder is

 vcyl = πr²h

the formula for the volume of a cone is

 vcon = (1/3)πr²h

here, we have r=h=9 in both cases, and we want to find the difference of volumes. filling in the numbers gives

 vcyl - vcon = π(9²)(9) - (1/3)(9²)(9) . . . matches choice a

comment on notation

exponents rarely get copied properly from other applications to brainly, so some editing may be required. if you don't use the equation editor or special mathematical symbols, the plain-text form for an exponent is

 (base)^(exponent) . . . the exponent is signified by a caret (^)

note that grouping symbols may be required. if the exponent has an arithmetic operation in it, then it needs parentheses:

 √(x) = x^(1/2)

 (x^a)(x^b) = x^(a+b)

the use of the word "over" to signify a fraction is unnecessary and ambiguous. the forward slash (/) is usually used for that purpose. as with the caret, any numerator or denominator consisting of more than a single number or letter needs parentheses: (1/a) + (1/b) = (a+b)/(ab). even if you know that the denominator is a single number, as in 1/3, it understanding to put the fraction in parentheses so the appropriate interpretation is clear. (see above for examples. many people write 1/x+1 when they mean 1/(x+1), so if you mean (1/x)+1, it is to write it that way--even though that is how it should be interpreted.)

Find a 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms. The 95% c
Sveta_85 [38]

Answer:

hello your question is incomplete attached below is the complete question

answer : ( 184.019 , 206.219 )

Step-by-step explanation:

The 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms can be calculated using this relationship below

y = Bo + B1 ( 200 )  = 195.118621 , sy =

hence a 95% confidence interval = 195.118621 ± 2.306( 4.813492) i.e.  ( 184.019 , 206.219 )

attached below is the remaining part the solution
