Percentage is a value by a fraction of 100.
120 marks is equivalent to 60%
this means from the whole amount, 60 % of the whole amount is 120 marks
we need to find the full marks
if 60 % --- 120
then 1 % --- $\frac{120}{60}$
full marks are 100 %
therefore 100 % - $\frac{120}{60} * 100$
100 % --- 200 marks
full marks are 200 marks

Since 120 is 60 percent we know that 2/3*120+120 will be 100 percent

2/3*120=80
so 80+120=200

So, full marks is 200

Choose the correct answer for each of the following questions Find the y-intercept for following equation F(X)=-(X+1)^21- -12- -

devlian [24]

Solution

Find the y-intercept for following equation:

$f(x)=-(x+1)^2$

Using the slope equation formular:

$\begin{gathered} y=mx+c \\ f(x)=-(x+1)^2 \\ f(x)=-x^2-2x-1 \end{gathered}$

The value of y when x = 0

$\begin{gathered} f(0)=-0^2-2(0)-1 \\ y=-1 \end{gathered}$

Hence the answer is - 1

The number of minutes Magdeline spent talking on her cell phone each month for the past five months were 494, 690, 502, 478, and

snow_lady [41]

Answer:

542 minutes

Step-by-step explanation:

currently our mean is =530

i got that by adding all the number out which equal too =2,650

and divide it by how many number there are which is 5

2,650/5=530

After some trial and error i found it

so you add 494+690+502+478+486+542=3,192

3,192/6=532

and that was our goal

so the 6th month she talked on the phone for 542 minutes

What is the equation of a line that passes through the points (-3, 4) and (2,8)?

ziro4ka [17]

Given that the line passes through the two points (-3,4) and (2,8)

We need to determine the equation of the line.

<u>Slope:</u>

The slope of the line can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the points (-3,4) and (2,8) in the above formula, we get;

$m=\frac{8-4}{2+3}$

$m=\frac{4}{5}$

Thus, the slope of the line is $m=\frac{4}{5}$

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Substituting the point (-3,4) and $m=\frac{4}{5}$ in the above formula, we have;

$y-4=\frac{4}{5}(x+3)$

$y-4=\frac{4}{5}x+\frac{12}{5}$

$y=\frac{4}{5}x+\frac{12}{5}+4$

$y=\frac{4}{5}x+\frac{32}{5}$

Thus, the equation of the line is $y=\frac{4}{5}x+\frac{32}{5}$
