Which of the following checks done during the exterior pre-trip inspection is impossible to complete by yourself?

Fraction is equivalent to a terminating decimal

The best way to compare fractions would be to make them have like denominators. We first , in this case, need to convert from decimal to fraction.

Converting decimals to fractions first requires an understanding of the decimal places that fall after the decimal. One place after the decimal is the tenths place. If you have a decimal that ends at one place after the decimal (or in the tenths place) it can be written as the number after the decimal in the top of the fraction and ten (tenths place) in the denominator. ex. .5 ends one place after the decimal and can be written as 5/10...(read as five tenths).

If a decimal ends at two places after the decimal...(ex. .75)...it ends in the hundredths place, can be written as that number in the numerator and 100 in the denominator....(ex 75/100) and is read as seventy-five hundredths.

one place after the decimal is tenths (over 10), two places is hundredths (over 100), three places is thousandths (over 1000) , four places ten-thousandths (over 10000) and so on.

Because each decimal in your problem has a different amount of decimal places, it makes for different denominators. But, We can add a zero to the end of a decimal without changing it's value; if we add a zero to the end of .5 and make it .50 , we then can write it as 50/100 and would now have like denominators.

if .5 = .50 = 50/100 and .75 = 75/100

we now have the question what fractions can fall between 50/100 and 75/100.

That would be fractions such as 51/100, 52/100, 53/100.......74/100.

A data analyst wants to set up a hypothesis test to determine if the mean number of courses taken in a college semester is diffe

Nadya [2.5K]

Answer:

Step-by-step explanation:

Hello!

What you want to test is if there is a difference between the number of courses taken by students of different years, you can determine 4 populations of students:

Population 1: Freshmen

Population 2: Sophomores

Population 3: Juniors

Population 4: Seniors

To each population you measured the study variable, setting 4 different variables. To compare these variables the best way is to make one test where you compare the four populations at the same time, so the hypothesis is:

H₀: μ₁ = μ₂ = μ₃ = μ₄

H₁: At least one of the population means is different from the others.

The most appropriate test to use to compare the population mean of the 4 groups is an ANOVA.

I hope you have a SUPER day!

Mark invests $4200 in two different accounts. The first account paid 3 %, the second account paid 7 % in interest. At the end of

nexus9112 [7]

Answer:

3% interest account = $2,700

7% interest account = $1,500

Step-by-step explanation:

We have to use equation to find the answer. Again, we are using simple interest to find how much is in each account.

We know, Interest = Capital x Interest rate x year

Let,

3% interest account = X

7% interest account = Y

According to the question,

X*0.03*1 + Y*0.07*1 = 186 ................. (i)

Again, X + Y = 4200 .................. (ii)

From equation (Ii), we get,

or X = 4,200 - Y ...................... (iii)

Putting the value of X in equation (i), we can get,

(4,200 - Y)*0.03*1 + Y*0.07*1 = 186

or, 126 - 0.03Y + 0.07Y = 186

or, 0.04Y = 186-126

or, 0.04Y = 60

or, Y = 1,500

Putting Y = 1,500 in equation (iii), we get

X = 4,200 - 1,500

X = 2,700

Therefore, 3% account had $2,700 balance

7% account had $1,500 balance.

Last winter, Tom earned $47.50 shoveling snow and $122 giving ice-skating lessons. During the summer, he earned twice as much by

siniylev [52]

You would have to add 47.50 + 122 to get 169.5 dollars. to get the amount of money he made in the summer, you would have to multiply 169.5 by 2 which would equal 339 dollars. so he made 339 dollars over the summer :)
