Answer:

g=8 and f=6

Step-by-step explanation:

Area of ABCD=f×g

or,48=fg

or,48/g=f.........(i)

we have,

AD=BC=f

Now,

Area of ABCD+Area of ADE=Area of ABCE

f×g+1/2×DE×AD=60

or,48/g×g+1/2×4×f=60

or,48+2f=60

or,2f=12

therefore,

f=6

And,

48/g=6

or,48=6g

therefore,

g=8

A Mathematics paper consists of 12 questions of which not more than ten are to be answered. Given that the number of candidates

RUDIKE [14]

The probability that a candidate chosen at random from among these two sets of candidates will have selected questions 1, 2 and 3 is 0.4179.

<h3>How to calculate probability?</h3>

The probability that a candidate chosen at random from among these two sets of candidates will have selected questions 1, 2 and 3 will ba calculated thus:

= [(9C6 /12C9) × 1/2] + [(9C7)/12C10) × 1/2]

= 42/220 + 18/66

= 0.1909 + 0.2727

= 0.4179

In conclusion, the probability is 0.4179.

Help!!!!!! show all work

Gnom [1K]

Hi There!

----------------------------------------------

Part A:

Slope Intercept Form: y = mx + b

m = slope (slope = $\frac{y2 - y1}{x2 - x1}$ )

b = y intercept

$m=\frac{4 - 6}{(-2)- (-6)} = \frac{-2}{4} = \frac{-1}{2}$

b = 3

Answer: y = -1/2x + 3

----------------------------------------------

Part B:

Just substitue f(x) for y.

Function Notation = f(x) -1/2 + 3

----------------------------------------------

Part C:

This function given looks almost the same but the slope is different while the one stated in the question has a slope of +2 and the equation given at the start with the slope being -1/2.

----------------------------------------------
