Answer:

<em>Neha and Daniel do not use the same ratio of bananas to oranges</em>

<em>Neha used the grater ratio of bananas to oranges</em>

Step-by-step explanation:

<u>Ratios</u>

The ratio is expressed as a:b, where a and b are whole numbers.

Neha used 4 bananas and 5 oranges in her fruit salad. Daniel used 7 bananas and 9 oranges in his.

We use cross multiplication to find if the ratios of bananas to oranges are the same.

Neha s ratio is 4:5

Daniel s ratio is 7:9

To compare both ratios we use the expression:

\displaystyle \frac{4}{5} =?\frac{7}{9}

The question mark means equality could be true or false.

The cross multiplication consists of multiplying the denominator of one side by the numerator of the other side:

4*9 =? 5*7

Operating:

36 =? 35

The equality is false, thus

Neha and Daniel do not use the same ratio of bananas to oranges

Since the left side of the equality is greater than the second:

Neha used the grater ratio of bananas to oranges

Classify each substance as either a conductor or insulator.
IceJOKER [234]

A sample of mercury-conductor

A piece of glass-insulator

A rubber hose-insulator

A negatively ionized lithium paste-conductor

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

Conductors are substances that allow the flow electricity through them whereas insulators do not permit the flow of electricity through them.

Mercury is  a liquid metal and due to its metallic nature, it is a fair conductor of electricity because metals have free electrons that carry the electric charge through the material.

Rubber and glass are insulators whereas a negatively charged lithium paste is a conductor.

Shalnov [3]

Answer:

P(X>4)=P(\frac{X-\mu}{\sigma}>\frac{4-\mu}{\sigma})=P(Z>\frac{4-4.4}{0.4})=P(z>-1)

And we can find this probability with the complement rule:

P(z>-1)=1-P(z

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the disagreements of a population, and for this case we know the distribution for X is given by:

X \sim N(4.4,0.4)  

Where \mu=4.4 and \sigma=0.4

We are interested on this probability

P(X>4)

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(X>4)=P(\frac{X-\mu}{\sigma}>\frac{4-\mu}{\sigma})=P(Z>\frac{4-4.4}{0.4})=P(z>-1)

And we can find this probability with the complement rule:

P(z>-1)=1-P(z
