sweet [91]3 years ago
5 0

The volume of the large cylinder will be twice the volume of the small cylinder.

<u>Step-by-step explanation:</u>

Let the radius of the cylinder be 'r'

Let the height of the cylinder be'h'

Volume of the small cylinder=π r² h

Volume of the large cylinder= π r² (2h)

Volume of large cylinder/volume of small cylinder= 2/1

The large cylinder volume is twice the volume of the small cylinder.

A horticulturist working for a large plant nursery is conducting experiments on the growth rate of a new shrub. Based on previou
Jet001 [13]

Answer:

Test statistic = - 3.354

We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.

Step-by-step explanation:

H0 : μ = 3

H1 : μ < 3

The test statistic = (xbar - μ) / (s/ √n)

Xbar = 1.50

μ = 3

s = 3

n = 45

Test statistic = (1.5 - 3) / (3/ √45)

Test statistic = - 1.5 / 0.4472135

Test statistic = - 3.354

Pvalue, using the Pvalue from Z score calculator :

Pvalue = 0.00039826

α = 0.05

Pvalue < α ; We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.

If f(x)=x+4/x, g(x)=x-2 and h(x)=4x-1 what is f(h(g(x)))?
Paul [167]

Answer:

hello : f(h(g(x)))= (4x - 9) + 4 /(4x - 9)

Step-by-step explanation:

calculate : h(g(x))  

h(g(x)) = h(x - 2) = 4 (x -2) -1 = 4x - 8 -1

h(g(x))  = 4x - 9

calculate : f(h(g(x)))

f(h(g(x))) = f (4x - 9) = (4x - 9) + 4 /(4x - 9)

How many significant figures will there be in the answer to the following problem?<br> 7500×45.0879
Alchen [17]
Two significant Figures I believe because you want to go with the least amount of sig figs that are already in your problem which would be 2 in 7500 because the zeros are not significant
