\qquad \qquad \huge \pink {\sf{☁Answer☁}} \\  \\

→ Here,

  • y varies directly as x means that y = kx
  • here value of (k) is not known

by substituting the values of x and y, y = 18 when x = 12

\rm{y = kx} \\  \\  \rm{18 = 12k} \\  \\ \rm{k =  \cancel \frac{18}{12} } \\  \\  \rm{ k = 1.5}

Now, substituting value of k nd x in y = kx

  • x = 132
  • k = 1.5
  • in y = kx

\rm{y = (1.5 \times 60 )} \\  \\ \rm{y = 90}

Leya [2.2K]

from what I know

A=4

B=3

C=2

and a plus adds 0.33 and a minus minuses 0.33

question wants us to find yearly average or average per 1 year

since these grades span over 2 years, we must divide the total average by 2

averagefresh=sum of fresh grades/4 grades per year

averagesoph=sum of soph grades/4 grades per year

yearlyaverage=(averagefresh+averagesoph)/2


freshman:

(C)+(B)+(A)+(C-)=2+3+4+(2-0.33)=10.67


sophomore:

(B+)+(A-)+(C+)+(B-)=(3+0.33)+(4-0.33)+(2+0.33)+(3-0.33)=12


averagefresh=10.67/4=2.6675

averagesoph=12/4=3

yearlyaverage=(2.6675+3)/2=2.83375

so it's about a B^{-} average

Answer:

The equation of the line is y = 3x + 3

Step-by-step explanation:

Looks like you've already found the y-intercept and slope of this graph. Great! That's all the info we need to create an equation.

The equation of a line is always in y = kx+b form, where k is the constant of proportionality (aka the slope) and b is the constant added (aka the y-intercept).

We know the slope is 3 and the y-intercept is 3, so we can put these values into the equation.

y = 3x+3

Hope this helped!

Step-by-step explanation:

A

The probability of wining is 1/4 so it's 25%. so if you win you either win one of 2 object, so we have to divide the chance of wining by the number of object, so (25%)/2

A it's ,12.5% chance of wining the mug

B yes, it will change if she pics the mug first, it will be 25% because it's guaranteed that she will get the mug if she wins
