LekaFEV [45]

Answer:

The choice C.

12 \frac{1}{2}

Step-by-step explanation:

( \frac{4}{5}  -  \frac{1}{3} ) \times  {5}^{2}   +  \frac{5}{6}  \\  \\ ( \frac{12}{15}  -  \frac{5}{15} ) \times 25 +  \frac{5}{6}  \\  \\ ( \frac{12 - 5}{15} ) \times 25 +  \frac{5}{6}  \\  \\ ( \frac{7}{15} ) \times 25 +  \frac{5}{6}  \\  \\  \frac{35}{3}  +  \frac{5}{6}  \\  \\  \frac{70}{6}  +  \frac{5}{6}  =  \frac{75}{6}  \\  \\  =  \frac{25}{2}  = 12 \frac{1}{2}

If y varies directly as x, and y is 12 when x is 1.2, what is the constant of variation for this relation? A) 1 B) 10 C) 10.8 D)
Anit [1.1K]
\bf \begin{array}{cccccclllll}&\\
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\&\\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\&\\
y&=&{{ k}}&\cdot&x&\\
&\\
&&  y={{ k }}x&\\
\end{array}& \\\\\\
\textit{we know that }
\begin{cases}
y=12\\
x=1.2
\end{cases}\implies y=kx\implies 12=k\cdot 1.2

solve for "k" to find "k", or the "constant of variation"

Write an expression that evaluates to true if the value of the integer variable number of prizes is divisible (with no remainder
natta225 [31]

Answer:

A=BQ

Step-by-step explanation:

In order to find an expression, you can use the definition of the dividend in a division:

A=BC + R

where A is the dividend, B is the divisor, Q is the quotient (the result of the division) and R is the remainder of the division.

Let A represent the integer variable number of prizes and B represent the integer variable number of participants.

In this case R=0 and B≠0, therefore:

A=BQ

A is divisible by B if A can be written as an integer multiple of B. In other words, you have to find an integer number Q that multiplied by B produces A.

<h3>What is the solution to the answer above?</h3>

Test Statistic F is given by:

= σ²₁/σ²₂

= 0.93²/1.08²

= (0.93/1.08)²

= 0.8611²
