Answer:

= 486 in²

Step-by-step explanation:

Linear scale factor = Image distance/object distance

Therefore; Linear scale factor = OL'/OL

                                                 = 54/ 12

                                                 = 9/2

Area scale factor is equivalent to the square of linear scale factor

Thus;

Area scale factor = (9/2)²

                             = 81/4

Hence; 81/4 = Area of larger rectangle/Area of smaller rectangle

Area of the smaller rectangle = 4 ×6 = 24 in²

Therefore;

Area of enlarged or larger pic = 81/4× 24

                                                  <u>= 486 in²</u>

The equation of this straight line is y = 50x + 100.

<h3>What is a linear function?</h3>

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

<h3>How to determine the equation?</h3>

In order to determine the equation from this graph of a linear equation, we would find the slope of the straight line by using this formula as follows:

Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope,\;m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}

Slope, m = 100/2

Slope, m = 50.

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

Where:

  • x and y are the points.
  • m is the slope.
  • c is the intercept.

At point (4, 300), we have:

y = mx + c

300 = 50(4) + c

300 = 200 + c

c = 300 - 200

c = 100.

Therefore, the equation of this straight line is y = 50x + 100.

I just stuck. Someone explain.
KatRina [158]

If there are parentheses you add the exponent on the outside to the exponents inside that belong to a variable.

For the three you would just cube it regularly, but for the x you would add the 3 to the 2 that is already on the x

Last school year, the student body of a local university consisted of 30% freshmen, 24% sophomores, 26% juniors, and 20% seniors
tino4ka555 [31]

Answer:

\chi^2 = \frac{(83-90)^2}{90} +\frac{(68-72)^2}{72}+\frac{(85-78)^2}{78}+\frac{(64-60)^2}{60} = 1.66

And the answer would be:

c. 1.66

Step-by-step explanation:

We need to conduct a chi square test

The statistic to check the hypothesis is given by:

\sum_{i=1}^n \frac{(O_i -E_i)^2}{E_i}

the observed values for this case are:

Freshemen=83

Sophomores=68

Juniors = 85

Seniors= 64

The expected values for this case are:

Fres_E =0.3*300= 90

Sop_E =0.24*300= 72

Jun_E = 0.26*300 =78

Sen_E = 0.20*300= 60

Then the statistic would be given by:

\chi^2 = \frac{(83-90)^2}{90} +\frac{(68-72)^2}{72}+\frac{(85-78)^2}{78}+\frac{(64-60)^2}{60} = 1.66

And the answer would be:

c. 1.66

Pls answer 10 points I will mark brainliest
Degger [83]

Answer:

  500 cm³

Step-by-step explanation:

Using the given values in the given formula, we find the volume to be ...

  V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}(3)(5\text{ cm})^3 = 4(125\text{ cm}^3) = \boxed{500\text{ cm}^3}

The volume of the sphere is about 500 cubic centimeters.

_____

<em>Additional comment</em>

The actual value of pi would add about 4.72% to this figure, bringing the estimate to about 523.6 cm³.
