A company says its premium mixture of nuts contains 10% Brazil nuts, 20% cashews, 20% almonds, and 10% hazelnuts, and the rest are peanuts. You buy a large can and separate the various kinds of nuts. Upon weighing them, you find there are 112 grams of Brazil nuts, 183 grams of cashews, 207 grams of almonds, 71 grams of hazelnuts, and 446 grams of peanuts. You wonder whether your mix is significantly different from what the company advertises. a) Explain why the chi-square goodness-of-fit test is not an appropriate way to find out. b) What might you do instead of weighing the nuts in or- der to use a test

Circumference of a circle with the given radius 36 inches

Answers

the answer is 226.19 in

Answer is 226.08 inches As circumference is 2πr Where π=3.14 radius r = 36 inches Circumference will be 2 π r 2 x 3.14 x 36 6.28 x 36 226.08 So the answer will be 226.08 inches

A sample of liquid has a mass of 24g and a volume of 16ml what is the density of the liquid

Answers

The density of the liquid will be 1500 kg per cubic meter.

What is density?

The density is the ratio of mass to volume of any substance.

Let m be the mass of the object and v be the volume of the object.

Then the density D will be

D = m / v kg / cubic m

More the density means the number of the molecules will be more in a unit volume.

A sample of liquid has a mass of 24g and a volume of 16ml.

We know that one kg equals to 1000 grams.

24 g = 0.024 kg

We know that one ml equal to 10⁻⁶ cubic meters.

16 ml = 16 × 10⁻⁶ cubic meters

Then the density of the liquid will be

Density = 0.024 / 16 × 10⁻⁶

Density = 1500 kg per cubic meter

Thus, the density of the liquid will be 1500 kg per cubic meter.

More about the density link is given below.

density = mass/volume

so,

The ideal width of a certain conveyor belt for a manufacturing plant is 50 in. Conveyor belts can vary from the ideal width by at most 7/32 in.

Answers

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

If the ideal is 50 and the max variation is 7/32in, then that's 7/32 under 50 and 7/32 over 50.
So, 50-7/32= 49 25/32, and 50+7/32 = 50 7/32.
So the acceptable width is 49 25/32 to 50 7/32.

Answer;

The acceptable width is 49 25/32 and 50 7/32

That is; 49 25/32 ≤ x ≥ 50 7/32

Explanation;

-If the ideal is 50 and the max variation is 7/32 inches, then that's 7/32 under 50 and 7/32 over 50.

Therefore; 50-7/32= 49 25/32, and 50+7/32 = 50 7/32.

x ≤ 50 7/32 and x ≥ 49 25/32

Thus; the acceptable width is 49 25/32 ≤ x ≥ 50 7/32.
