Show your mastery of multiplying fractions by using the sketchpad to find the product of 3-4 x 37

Answer:

\frac{111}{4}

or

27 \frac{3}{4}

Step-by-step explanation:

Any regular whole number (37 for example) is over one so it would look like \frac{37}{1}. Multiplying fractions involve just multiplying the numerators and denominators together, therefore it would look like \frac{3}{4}×\frac{37}{1}. Now just multiply the top and bottom numbers together and this will leave you with \frac{111}{4} . But if you'd like to make it into a mixed number (more simplified version of \frac{111}{4} ) then you would get 27 \frac{3}{4}.

A box of chocolates contains bars of milk chocolate and dark chocolate. The weight of each bar of milk chocolate and dark chocol
Luden [163]

Answer:

7 milk chocolate

19 dark chocolate

Step-by-step explanation:

It is 2950 ounces in total, and dark chocolate is 100 ounces per bar and milk chocolate is 150 ounces per bar. There are 12 more dark chocolate bars so I multiplied 12 by 100 and that was 1,200. Then I took 2,950-1200=1,750. From there I subtracted 150 and 100 till I got to 0.

Suppose researchers are concerned about the rate of residents reporting no access to health insurance in a particular community.
o-na [289]

Answer:

a) The expected number of households that will have no insurance is 2.4.

b) The standard deviation is 1.3505.

Step-by-step explanation:

For each resident, there are only two possible outcomes. Either they have health insurance, of they do not. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected number of successes is given by:

E(X) = np

The standard deviation is given by:

\sqrt{Var(X)} = \sqrt{np(1-p)}

In this problem, we have that:

A group of 10 households, so n = 10.

24% of residents are living without health insurance, so p = 0.24.

a. What is the expected number of households that will have no insurance?

E(X) = np = 10*0.24 = 2.4

The expected number of households that will have no insurance is 2.4.

b. What is the standard deviation?

\sqrt{Var(X)} = \sqrt{np(1-p} = \sqrt{10*0.24*0.76} = 1.3505

The standard deviation is 1.3505.

Undefined (not a real number)

The square root of -256 would result in an imaginary number so by terms, it's "not real". The imaginary number would be 16i. 16x 16 =256, but since it's negative, it's √16 √16i.

Is absolute value number 6 equal to absolute value NEGATIVE 6?
andreyandreev [35.5K]

Answer:

c

Step-by-step explanation:

The symbol for absolute value is two straight lines surrounding the number or expression for which you wish to indicate absolute value. |6| = 6 means the absolute value of 6 is 6. 6 is 6. 2 minus x.
