Are 16% of M&M’s Green? Mars, Inc. claims that 16% of its M&M plain candies are green. A sample of 100 M&Ms is rando

wolverine [178]

Answer: This result is not unusual.

So, it does not seem that the claimed rate of 16% is wrong

Step-by-step explanation:

Since we have given that

n = 100

p = 0.16

q = 1 - 0.16 = 0.84

So, Mean would be

$np=100\times 0.16=16$

and standard deviation would be

$\sqrt{np(1-p)}=\sqrt{100\times 0.16\times 0.84}=3.67$

Now, if there are 19 green,

so, we will check how it is far,

$\dfrac{19-16}{3.67}=\dfrac{3}{3.67}=0.817$

Since it is 0.817 standard deviations away from the mean.

So, this result is not unusual.

So, it does not seem that the claimed rate of 16% is wrong.

A sphere has a radius of 2.7 centimeters what is it’s volume to the nearest cubic centimeter

-BARSIC- [3]

Answer:

The volume of the sphere is 82.4 cubic centimetre

Step-by-step explanation:

Given:

The radius of the sphere = 2.7 centimetres

To Find:

The volume to the nearest cubic centimetre = ?

Solution:

The volume of the sphere = $\frac{4}{3} \pi r^3$

where r is the radius

On substituting the values,

V = $\frac{4}{3} \pi(2.7)^3$

$V = \frac{4}{3} \pi(2.7)^3$

$V = \frac{4}{3} \pi(19.683)$

$V = \frac{78.732}{3} \pi$

$V= 26.244 \times \pi$

V = 82.4 cubic centimetre
