What is the geometric mean between 1 and 16?
vladimir2022 [97]
-4 is also a geometric mean

if we consider a(first element in series)=1 and r(common ratio)=-4 then the series would be

1,-4,16,-64,256,…..,a(-4)^(n-1 )

where n is nth term

from this -4 would be the geometric mean if we consider -4 as common ratio .

If we consider 4 as common ratio then geometric mean should be 4

so you should mention whether common ratio >0 or not (r>0 or not) .

[without ‘r’ value you can’t solve the question but in general most of the teachers will consider r>0.]

So, -4 won’t be geometric mean of 1 & 16

Ten less than 5 times the value of a number is equal to 10 times the quantity of
grandymaker [24]

Answer:

52

Step-by-step explanation:

given that the number is a

The expression for Ten less than 5 times the value of a number is given by

5a - 10

10 times the quantity of  12 more than one-fourth of the number.

a/4 is one-fourth  of number

12 more than one-fourth of the number

a/4 + 12

expression for  10 times the quantity of  12 more than one-fourth of the number. is given by

10(a/4 + 12) = 10a/4 + 12*10 = 2.5a + 120

Given that the above two expression are equal

equating them we have

5a - 10 = 2.5a + 120

adding 10 both sides

=>5a - 10+ 10  = 2.5a + 120 + 10

=> 5a = 2.5a + 130

subtracting 2.5a from both sides

=> 5a - 2.5a = 2.5a + 130 - 2.5a

=> 2.5a = 130

dividing both side by 2.5

=> a = 130/2.5 = 52

Thus, value of a is 52

natka813 [3]

Answer:

0.411^5 times 0.599

Step-by-step explanation:

0.599 chance of landing on heads.

0.411 chance of not landing on heads.

0.411 times 0.411 times 0.411 times 0.411 times 0.411 (for the 5 flips that do not land on heads) times 0.599 (for the time that it does land on heads).
