What integer is having 3 dollats
faust18 [17]

Answer:

Why is 3 an integer?

They are the numbers you usually count and they will continue on into infinity. Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4… Integers include all whole numbers and their negative counterpart e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4

The ratio of boys to girls in the entire 6th grade is 3 to 2. Given this ratio, which two class compositions are possible?
gtnhenbr [62]

Answer:

<em>There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:</em>

<em>There might be 3 boys and 2 girls.</em>

<em>There might be 6 boys and 4 girls.</em>

<em>There might be 9 boys and 6 girls.</em>

<em>There might be 12 boys and 8 girls.</em>

<em>etc...</em>

<em>In each case the ratio stays the same - 3 : 2.</em>

<em>Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.</em>

Step-by-step explanation:<em>hope this help.</em>

Suppose flights on standard routes between two given cities use on average 3,087 gallons of kerosene with standard deviation of
Radda [10]

Answer:

15.866%

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 3,282 gallons of kerosene

μ is the population mean = 3,087 gallons of kerosene

σ is the population standard deviation = 195 gallons

For x > 3282 gallons

z = 3282 - 3087/195

z = 1

Probability value from Z-Table:

P(x<3282) = 0.84134

P(x>3282) = 1 - P(x<3282) = 0.15866

Converting to percentage

0.15866 × 100 = 15.866%

The percent of flights on these particular routes that will burn more than 3,282 gallons of kerosene is 15.866%

48/8=42/x <br> x=42<br> x=7<br> x=8<br> x=6
DedPeter [7]

Answer:

x=7

Step -by -step explanation:

Given that,

\frac{48}{8}= \frac{42}{x}

We first simplify the left hand side of the equation to obtain

6=\frac{42}{x}

we then cross multiply to get

6x=42

We divide both sides of the equation by the coefficient of x (i.e 6) to get the value of x.

\implies\frac{6x}{6}=\frac{42}{6}

Therefore,

x=7
