A gallon of gas costs $4.34.Greg puts 12 gallons of gas in his car,He has a 50-dollar bill.Tell how much Greg will have left,or

Lerok [7]

Greg will need $2.08 more money to buy 12 gallons of gas.

<h3>Further explanation</h3>

A gallon of gas costs $4.34

Greg puts 12 gallon of gas

Greg has $50

First, we are going to calculate how much money does Greg needs for 12 gallon of gas:

= 12 gallon of gas x cost/gallon

= 12 x 4.34

= 52.08

To multiply the decimal it's just the same way as the whole number multiplication, except for the placement of the decimal point in the answer. For the example

4.34 ⇒ 2 decimal place

<u> 12 x</u> ⇒ 0 decimal place

868

52.08 ⇒ 2 decimal place

By doing the same process as the whole number multiplication we got the answer is 52.08, but don't forget to add the decimal point/decimal place. The first factor has 2 decimal place, the second factor has 0 decimal place, so the answer will have two decimal place (2+0 = 2), by adding the decimal place.

The next step , 12 gallon of gas cost $52.08, if he has $50 so it cost more than the money he has, We are going to do a subtraction:

$52.08

<u>$50.00 </u>- ⇒ <em>we put zero so we can the borrowing (regrouping)</em>

$ 2.08

To subtract a decimal number, we need to line up the decimal point, add trailing zero as a placeholder and then do the subtraction

Square GYTD has vertices G(−4,3) , Y(0, 3) , T(0,−1) and D(−4,−1) . Square GYTD is translated 2 units left and 2 units up to

Sliva [168]

we know that

If square GYTD is translated $2$ units left and $2$ units up to produce square G'Y'T'D'

that means

the rule of transformation is

$(x,y)-------> (x-2,y+2)$

<u>Find the coordinates of the image</u>

$G (-4,3)------->G'(-4-2,3+2)=G'(-6,5)$

$Y (0,3)------->Y'(0-2,3+2)=Y'(-2,5)$

$T (0,-1)------->T'(0-2,-1+2)=T'(-2,1)$

$D (-4,-1)------->D'(-4-2,-1+2)=D'(-6,1)$

therefore

<u>the answer is the option</u>

G'(−6, 5), Y'(−2, 5), T'(−2, 1) , and D′(−6, 1)

Students who have completed a speed reading course have reading speeds that are normally distributed with a mean of 950 words pe

VikaD [51]

Answer:

36.04% probability that at most two of them would read at less than 850 words per minute

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the binomial probability distribution.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Percentage of students who read less than 850 words per minute.

Pvalue of Z when X = 850. The mean is $\mu = 950$ and the standard deviation is $\sigma = 200$

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{850 - 950}{200}$

$Z = -0.5$

$Z = -0.5$ has a pvalue of 0.3085.

30.85 of students read less than 850 words per minute.

If 10 students are selected at random, what is the probability that at most two of them would read at less than 850 words per minute

This is $P(X \leq 2)$ when $n = 10, p = 0.3085$ . So

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{10,0}.(0.3085)^{0}.(0.6915)^{10} = 0.0250$

$P(X = 1) = C_{10,1}.(0.3085)^{1}.(0.6915)^{9} = 0.1115$

$P(X = 2) = C_{10,2}.(0.3085)^{2}.(0.6915)^{8} = 0.2239$

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0250 + 0.1115 + 0.2239 = 0.3604$

36.04% probability that at most two of them would read at less than 850 words per minute

patricia wants to have her living room carpet cleaned she found three different companies that would clean the carpet for $198 t

topjm [15]

Answer:

company 1 final price: $148.5

company 2 final price: $168

company 3 final price: $132

thus, the best choice is company 3 because it costs the least and all services are the same

Step-by-step explanation:

company 1 is offering 25% off the price of their service

company 2 is offering $30 off the price of their service

company 3 is offering a 1/3 discount off the price of their service

the price of the cleaning is $198

company 1: 25% discount = 75% of the original price $198, which would be $198 * 3/4, or $148.5

company 2: $30 dollars off, which means $198 - $30 or $168

company 3: 1/3rd discount, meaning the product after the discount is only 2/3rd of the original price. 2/3rd of $198 is $132, so the final price after the discount is $132
