Answer:

11.88... below is the explanation,... ;->

Step-by-step explanation:

1.35 * 8.8 = 11.88

The fastest and simplest way to remember how to multiply decimals is in the following:

#1: Take away the decimal points (1.35 becomes 135 and 8.8 becomes 88).

#2: Multiply the numbers as whole numbers (135 * 88 = 11880).

#3: Look at the original decimals you were trying to multiply and see how many numbers where on the RIGHT side of the decimal point. In the decimal 1.35 there are 2 numbers to the RIGHT side of the decimal point (1.35 (the 3 and the 5)). In the decimal 8.8 there is 1 number to the RIGHT of the decimal point (8.8 (the 8))

#4: You have 3 numbers between both of your decimals that are on the RIGHT of the decimal point (the 3 and the 5, and then the 8) so the final step is take the number 11880 (currently the decimal point is at 11880.0) and move it 3 spaces to the LEFT of the decimal point (one 1188.0) (two 118.80) (three 11.880) and that is your final answer,...

Hope that helped,... Chow,...!

1. Explain a method of determining the correct degree and classification of a polynomial.

Rainbow [258]

A polynomial can be classified according to the number of expressions that it has in a given equation. A monomial has only one expression having a coefficient (number) and a variable (letter). A binomial has two expressions, same as the definition of the monomial. And a trinomial has three expressions, same as the definition of a monomial. We can determine the degree of a polynomial by looking at the exponents of the given polynomial. If an expression has two variables with different exponents, you can add their exponent to determine their degree.

So the polynomial, 4x²y + 5xy is classified as a 3rd degree binomial because the first term, 4x²y has a variables x² and y. The x² has an exponent 2 and y has an exponent 1. Adding the two makes it three.

Lily has $2. 75 in her pocket, consisting of dimes and quarters. If there are 17 coins in all, how many of each does she have?.

Nikitich [7]

Answer:

Lily has 7 Quarters and 10 Dimes

Step-by-step explanation:

Let's use pennies instead of $.

Let D and Q stand for the numbers of Dimes and Quarters, respectively.

We are told that there are 17 coins total:

D + Q = 17

We also learn that they amount to 275 (pennies). We can write that as:

10D + 25Q = 275 [Each D is worth 10 pennies, etc.]

We have two equations and two unknowns. We can rearrange one equation to find the value of either of the unknowns, and then use that it the second equation.

I'll rearrange the first:

D + Q = 17

D = 17 - Q

Now use this value of D in the second equation:

10D + 25Q = 275

10(17-Q) + 25Q = 275

170 - 10Q + 25 Q = 275

15Q = 105

Q = 7 : 7 Quarters.

Since D + Q = 17:

D + 7 = 17

D = 10 Dimes

==========================================

Let's check these results:

Q = 7 Quarters

D = 10 Dimes

1. Is this 17 coins in total? (7+10 = 17) YES

2. Does this add to $2.75? (10*10) + (7*25) = 275 cents?

(100 + 176) = 275 (cents) YES

============================

Lily has 7 Quarters and 10 Dimes

According to a recent study of 7335 young people in the US, 30% had been arrested for a crime other than a traffic violation by

victus00 [196]

Answer:

a) Statistic.

b) The population proportion is expected to be between 0.29 and 0.31 with a 94% degree of confidence.

Step-by-step explanation:

a) The proportion of 30% is a statistic, as it is a value that summarizes data only from the sample taken in the study from USA Today. Other samples may yield different proportions.

b) We can use the statistic to estimate a confidence interval for the parameter of the population.

The standard error for the proportion is calculated as:

$\sigma_p=\sqrt{\dfrac{p(1-p)}{N}}=\sqrt{\dfrac{0.3\cdot 0.7}{7335}}=\sqrt{2.83\cdot10^5}= 0.00535$

The margin of error is 0.01. We can use this value to determine the level of confidence that represents.

The formula for the margin of error is:

$E=z\cdot \sigma_p=0.01\\\\z\cdot 0.0535=0.01\\\\z=1.87$

This z-value, according to the the standard normal distribution, corresponds to a confidence interval of 94%.

The interval for this margin of error is:

$p-E\leq \pi \leq p+E\\\\0.30-0.01\leq \pi \leq 0.30+0.01\\\\0.29\leq \pi \leq 0.31$

Then, we can conclude that the population proportion is expected to be between 0.29 and 0.31 with a 94% degree of confidence.
