Answer:

5 cm

Step-by-step explanation:

The formula for the volume of a cylinder is

V = πr²h

Data:

V = 1726 cm³

h = 22 cm

Calculation:

1726 = 3.14 × r² × 22

1726 = 69.08r²

Divide each side by 69.08

24.99 = r²

Take the square root of each side

r = 4.999 cm ≈ 5 cm

The approximate radius of the cylinder is 5 cm.

For the statement? below, write the claim as a mathematical statement. State the null and alternative hypotheses and identify wh
snow_tiger [21]

Answer:

Option E - sigma greater than or equal to $327

Step-by-step explanation:

In this question, we are testing whether the standard deviation of the base price of a certain type of all-terrain vehicle is at least $327.

Now, standard deviation is denoted by the symbol sigma(σ). Since the test is saying it should be at least $327, it means it should either be equal to $327 or greater than $327.

Thus, we would use the symbol ≥ which means "greater than or equal to".

Thus, the claim as a mathematical statement would be;

sigma greater than or equal to $327

steposvetlana [31]

Answer:

Expand  -3(9-x): -27 + 3x

Step-by-step explanation:

-3(9-x)

Apply the distributive law: a(b-c)=ab-ac

a = -3, b=9, c=x

=-3*9-(-3)x

Apply minus - plus rules:

-(-a)=a

= -3*9+3x

Multiply the numbers: 3 * 9 = 27

=-27+3x

Hope this helps! If so, may I get Brainliest and a Thanks?

Thank you, have a good one! =)

Digiron [165]

Answer:

10 hours

Step-by-step explanation:

45 pages per 1 hour and 30 minutes,  or 60 min +30 min =90 min

90 minutes / 45 pages has to be equal to an equivalent fraction where we have 300 pages

90 minutes /45 pages = ? minutes / 300 pages , multiply both sides by 300

? minutes = 90*300/45 = 600 minutes

to read 300-page book will take 600 minutes = 10 hours
