Answer:

16 cups of formula

Step-by-step explanation:

you take 16 (<em>the amount of bottles)</em> and multiply it by 4 (<em>the amount one bottle holds</em>)

which gets you 64 then you multiply that by 2 (<em> the amount of children</em>)

which gets you 128

then you divide by 8, because there are <em>8 fl oz in a cup</em>

which gets you 16

16 cups of formula

The scale drawing of a rectangular room measures 10cm long by 6cm wide. The actual width of the room is 9 metres. What is the ac
Snezhnost [94]

Answer:

48 meters

Step-by-step explanation:

The first thing is to calculate the scale, since we know both widths it is possible:

we pass the 9 meters to centimeters = 900 cm

900/6 = 150

So the scale would be 1: 150

Which means that the length is 150 times bigger.

10 * 150 = 1500cm or what equals 15m

the perimeter is the sum of all the sides, therefore:

P = 15 + 15 + 9 + 9

P = 48

Which means that the perimeter of the room is 48 meters

Find the volume of this cylinder. give your answer to 1 decimal place base is 11cm. length is 14cm
nlexa [21]

Answer:

Volume = 1330.6cm³

Step-by-step explanation:

Step one

This problem bothers on the mensuration of solid shapes a cylinder.

We know that the volume of a cylinder is expressed as

V= πr²h

Step two

Given data

Base of the cylinder /diameter = 11cm

Hence radius = 11/2= 5.5cm

Length /height of cylinder = 14cm

Step three

Substituting our given data we have

Volume = 3.142*(5.5)²*14

Volume = 3.142*30.25*14

Volume = 1330.637cm³

to 1 decimal place we have

Volume = 1330.6cm³

A group of 26 canadians were randomly selected among a local group of fitness enthusiasts to participate in an innovative fitnes
Lady_Fox [76]

The appropriate statistical procedure to use here is a two-tailed hypothesis test for the population mean

What is standard deviation?

  • The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean.
  • A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Explanation:

  • Since we are interested in comparing here the mean heart rate for Canadians who participated in this fitness program, to that of the national average,
  • We have to have to conduct a hypothesis test here for sample mean
  • Since we are not trying to find the true population mean based on the sample mean, we do not have to construct a confidence interval
  • As the sample size, n = 26 < 30,therefore we will use the t-test instead of the z-test.

Therefore,  A one-sample t-test for means' is the correct choice.
