Answer:

The  probability that a new fridge does not have a fault

q = 0.985

Step-by-step explanation:

Explanation:-

Given that the probability that a new bridge has a fault = 0.015

That is  'p' = 0.015

we have to find that  the probability that a new fridge does not have a fault

The  probability that a new fridge does not have a fault

         q = 1-p

   ⇒  q =1 - 0.015

        q = 0.985

Answer:

Scale factor(k) = 1/4, and centered at (5, -5).

Labelled the given figure as A, B and C.

The coordinates of the given triangle ABC are;

A = (-3, 7)

B = (-7, -5)

C = (9, 3)

To find the image of the figure after a dilation with scale factor 1/4 centered at (5, -5).

The rule of dilation with scale factor 1/4 and centered at (5, -5) is given by;

(x, y) \rightarrow (\frac{1}{4}(x-5)+5, \frac{1}{4}(y+5)-5)(x,y)→(

Answer:

Expression for area = 3x² - 15x - 42

Step-by-step explanation:

Given that:

Length of rectangle desktop = 3(x+2) = 3x+6 units

Width of rectangle desktop = x - 7

Area of rectangle desktop = Length * Width

Area of desktop = (3x+6)(x-7)

Area = 3x(x-7) +6(x-7)

Area = 3x² - 21x + 6x - 42

Area = 3x² - 15x - 42

Hence,

Expression for area = 3x² - 15x - 42

Answer:

c

Step-by-step explanation:

Answer:

1. 9 inches, 12 inches and 15 inches

2. 54 square inches

Step-by-step explanation:

1. The first part of this question would lead to a quadratic equation. Let the shorter leg be represented by x.

shorter leg = x

other leg = x + 3

hypotenuse = 15 inches

Applying the Pythagoras theorem, we have;

[tex]/15/^{2}[/tex] = [tex]/x/^{2}[/tex] + [tex]/x+3/^{2}[/tex]

225 = [tex]x^{2}[/tex] + [tex](x+3)^{2}[/tex]

225 = [tex]x^{2}[/tex] + [tex]x^{2}[/tex] + 6x + 9

       = 2[tex]x^{2}[/tex] + 6x + 9

2[tex]x^{2}[/tex] + 6x + 9 - 225 = 0

2[tex]x^{2}[/tex] + 6x - 216 = 0

divide through by 2 to have

[tex]x^{2}[/tex] + 3x - 108 = 0

From the quadratic formula;

x = (-b ± [tex]\sqrt{b^{2}-4ac }[/tex] ) ÷ 2a

but, a = 1, b = 3, c = -108

x = (-3 ± [tex]\sqrt{(3)^{2}-4(1)(-108)}[/tex]) ÷ 2

  = (-3 ± [tex]\sqrt{441}[/tex]) ÷ 2

= (-3 ± 21) ÷ 2

Thus,

x = (-3 + 21) ÷ 2 OR x = (-3 - 21) ÷ 2

x = 9 OR x = -12

So that, x = 9 inches

The shorter leg is 9 inches, and the other leg is 12 inches.

2. The area of the triangle can be determined by applying Heron's formula:

A = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

where s is the average value of the sum of the three sides a, b, and c.

Let, a = 9, b = 12 and c = 15

s = [tex]\frac{a +b+c}{2}[/tex]

  = [tex]\frac{(9+12+15}{2}[/tex]

  = 18

A = [tex]\sqrt{18(18-9)(18-12)(18-15)}[/tex]

   = [tex]\sqrt{18*9*6*3}[/tex]

   = [tex]\sqrt{2916}[/tex]

A = 54

Area of the triangle is 54 square inches.

Answer:

The function that best models the given data is;

B. h(t) = -6.73·t² + 14.19·t + 0.83

Step-by-step explanation:

The data in the given table is presented as follows

[tex]\begin{array}{cccccc}Time, \, t(s)&0&0.5& 1.0 & 1.5& 2.0\\Height, \, h \, (m) & 1.0 & 5.42 & 9.71 & 5.9 & 2.6\end{array}[/tex]

Where;

Time, t(s) is the independent variable

Height, h(m) is the dependent variable

Therefore, we have;

When t = 0, h = 1.0

From the given functions, we have the following table of the result of the function generated with Microsoft Excel

[tex]\begin{array}{cccccc}\\t & h & A & B & C& D\\0 & 1.0 & 1.22 & 0.83& 0.83& 1.22\\0.5 & 5.42 & 5.26 & 6.2425 & 9.6075 & 10.17\\1 & 9.71 & 4.39 & 8.79 & 21.75 & 24.03 \\ 1.5 & 5.9 & -1.39& 6.9725& 37.2575 &42.8\\2& 2.6 & -12.08 & 2.29 & 56.13 & 66.48\end{array}[/tex]

By comparison, the function that nest models the given data is the function 'B', given as follows;

h(t) = -6.73·t² + 14.19·t + 0.83.

The proportional relation between time and pushups is given by y = ( 1/6 )x

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

Let the number of pushups be y

Let the total time be represented as x

And , when x = 24 , y = 4

So , 4 = k ( 24 )

Divide by 24 on both sides , we get

k = ( 1/6 )

Therefore , the proportionality constant is k = ( 1/6 )

Hence , the equation is y = ( 1/6 )x
