Question Completion

PIE CHART NUMBERS:

Excellent 9%
Good 41%
Fair 36%
Poor 13%
Other 1%

Answer:

0.000063

Step-by-step explanation:

Number of Respondents, n=1400

Probability that they would rate their financial shape as excellent = 0.09

Number of Those who would rate their financial shape as excellent

=0.09 X 1400

=126

Therefore:

The probability that 4 people chosen at random would rate their financial shape as excellent

$=\dfrac{^{126}C_4 \times ^{1400-126}C_0}{^{1400}C_4} \\=\dfrac{^{126}C_4 \times ^{1274}C_0}{^{1400}C_4}\\=0.000063 $(correct to 6 decimal places)$

Martin wants to build an additional closet in a corner of his bedroom. Because the closet will be in a corner, only two new wall

Gekata [30.6K]

The relationship between the length & the width of the closet and the length of the wall is an illustration of a linear equation.

The equation for f(l) is: $f(l) = 1.5l$ .
The desired length and width are 8m and 4m

Given that:

$l = 2w$

Divide both sides by 2

$w = 0.5l$

Equation of f(l)

The sum of the length and the width is represented as: f(l).

So, we have:

$f(l) = l + w$

Substitute $w = 0.5l$

$f(l) = l + 0.5l$

$f(l) = 1.5l$

See attachment for the graph of f(l)

The desired dimension

From the question, we understand that the total length is 12m.

This means that:

$f(l) = 12$

So, we have:

$1.5l = 12$

Divide both sides by 1.5

$l = 8$

Recall that:

$w = 0.5l$

$w = 0.5 \times 8$

$w = 4$

Hence, the desired length and width are 8m and 4m, respectively.
