Rounding 17.2 to one significant figure gives you 17. This is because when the digit after the decimal point is below 5, you simply keep the number as is, but if it's 5 or above, you round up.

tester [12383]
Sari's claim is incorrect because dividing 120.78 by 9.9 equals approximately 12.2, and since 12 is less than 12.2, her estimate is not actually greater than the true result.

Which expression is equivalent to StartFraction 3 x Superscript negative 6 Baseline y Superscript negative 3 Baseline Over 15 x
zzz [12365]

Answer:

The appropriate expression is 1 Over 5 x Superscript minus 8 Baseline y Superscript minus 13 Baseline EndFraction

Step-by-step explanation:

In order to simplify the expression \frac{3x^{-6}y^{-3} }{15x^{2}y^{10} } where x ≠ 0, y ≠ 0, we must work through the given expression.

\frac{3x^{-6}y^{-3} }{15x^{2}y^{10} }\\= \frac{3}{15} x^{-6-2}y^{-3-10}\\ = \frac{3}{15}x^{-8}y^{-13} \\ =\frac{1}{5}x^{-8}y^{-13} \\

The appropriate expression is 1 Over 5 x Superscript minus 8 Baseline y Superscript minus 13 Baseline EndFraction

Marc mows lawns for $25 each lawn, plus $5 for every hour he spends mowing. The equation for his total earnings per lawn is y =
tester [12383]

Answer:

The constant pay of $25 signifies the intercept

Step-by-step explanation:

To address this query, we first need to comprehend and relate it to the formula for a straight line.

i.e y= mx+c  this represents the line's equation

where m= slope

           y= dependent variable

           x= independent variable

          c= intercept

Given

y= 25+5h

by comparing the two expressions, we can observe that

25 is equivalent to c, which denotes the intercept

Step-by-step explanation:

Meaning of each probability:

P(H): Likelihood of the game occurring at home

P(W): Likelihood of the game resulting in a win.

P(H and W): Likelihood that the game is both at home and a win.

P(H|W): Likelihood of a win occurring when at home.

P(W|H): Likelihood of winning at home games.

Which probabilities are necessary to determine the fraction of home games that were victories?

This is the probability of winning a home game. Hence, the answer is:

E. P(W | H)
