<h2><u>Given</u> :</h2>

Length of parallel sides = 10 cm and 12 cm

Height = 7 cm

<h2><u>What </u><u>To</u><u> Find</u> :</h2>

Area of trapezium

<h2><u>Formula</u><u> Using</u> :</h2>

\begin{gathered} {\underline{\boxed{ \rm {\red{Area  \: of \:  trapezium \:  =  \:  \frac{1}{2} \:  \times  \: (a \:  +  \: b) \:  \times  \:Height }}}}}\end{gathered}

Where ,

  • a and b is Parallel sides

<h2><u>Solution</u> :</h2>

\begin{cases}  \large\bf\purple{ \implies} \rm \:Area  \: of \:  trapezium \:  =  \:  \frac{1}{2} \:  \times  \: (10 \:  +  \: 12) \:  \times  \:7 \\  \\  \large\bf\purple{ \implies} \rm \:Area  \: of \:  trapezium \:  =  \:  \frac{1}{2} \:  \times  \: 22\:  \times  \:7 \\  \\  \large\bf\purple{ \implies} \rm \:Area  \: of \:  trapezium \:  =  \:  \frac{1}{ \cancel2} \:  \times   \:  \cancel{22} \:  ^{11} \:  \times  \:7 \\  \\ \large\bf\purple{ \implies} \rm \:Area  \: of \:  trapezium \:  =  \:11 \:  \times  \: 7 \\  \\ \large\bf\purple{ \implies} \rm \:Area  \: of \:  trapezium \:  =  \:77 \:  {cm}^{2}  \end{cases}

Answer:

77 cm²

Step-by-step explanation:

We know that

Area of trapezium = ½ (a + b) × h

Area = ½ × (10 + 12) × 7

Area = ½ × 22 × 7

Area = 11 × 7

Area = 77 cm²

The vertex of the parabola below is at the point (1,3), and the point (2,6) is
Inessa05 [86]

Answer:

B. y=3(x-1)2 + 3

Step-by-step explanation:

Given that

vertex of the parabola is at the point (1,3)

let's verify, if the option B is the correct equation of the parabola.

y=3(x-1)^2 + 3\\ \\y=3(x^2+1-2x) + 3\\\\y=3x^2+3-6x + 3\\\\y=3x^2-6x + 6....Eq1

comparing to standard equationof parabola (standard quadratic equation), we get

a=3, b=-6 and c=6

to find the vertex we use formula for x- coordinate as x=-b/2a

x=-(-6)/2(3)\\\\x=6/6\\x=1

to find y put x=1 in the Eq1, we get

y=3(1)^2-6(1)+6\\\\y=3-6+6\\\\y=3

vertex =(x,y) = (1, 3)

thus vertex of the parabola from the equation y=3(x-1)2 + 3 is (1,3), thus verified

For a specific species of fish in a pond, a wildlife biologist wants to build a regression equation to predict the weight of a f
sashaice [31]

Answer: First of all, we will add the options.

A. Yes, because 3 inches falls above the maximum value of lengths in the sample.

B. Yes, because the regression equation is based on a random sample.

C. Yes, because the association between length and weight is positive.

D. No, because 3 inches falls above the maximum value of lengths in the sample.

E. No, because there may not be any 3-inch fish of this species in the pond.

The correct option is D.

Step-by-step explanation: It would not be appropriate to use the model to predict the weight of species that is 3 inches long because 3 inches falls above the maximum value of lengths in the sample.

As we can see from the question, the model only accounts for species that are within the range of 0.75 to 1.35 inches in length, and species smaller or larger than that length have not been taken into consideration. Therefore the model can not be used to predict the weights of fishes not with the range accounted for.
