Vicky drew a scale drawing of a city. She used the scale 1 inch : 2 yards. If the actual width of a neighborhood park is 62 yard

klemol [59]

Answer:

The park is <u>31 inches</u> wide in the drawing.

Step-by-step explanation:

Given:

Vicky drew a scale drawing of a city. She used the scale 1 inch : 2 yards.

The actual width of a neighborhood park is 62 yards.

Now, to find the width of park in drawing.

Let the width of park in drawing be $x.$

The scale drawing of the city is 1 inch : 2 yards.

So, 1 inch is equivalent to 2 yards.

Thus, $x$ is equivalent to 62 yards.

Now, to get the width of park in drawing by using cross multiplication method:

$\frac{1}{2} =\frac{x}{62}$

By cross multiplying we get:

$62=2x$

Dividing both sides by 2 we get:

$31=x$

$x=31\ inches.$

Therefore, the park is 31 inches wide in the drawing.

If a sample proportion is 0.65, which range of possible values best describes

Snezhnost [94]

The range of possible values that best describes an estimate for the population parameter is; (0.5, 0.8)

<h3>How to estimate proportion?</h3>

The range of possible values that best describes an estimate for the population parameter is; (0.5, 0.8).

When we are talking about population parameters, we also have to look at the way of estimating the population, we have to add two extremes and divide by 2.

Thus, the correct one is;

(0.5 + 0.8)/2 = 0.65

Find the midpoint of segment JT when the coordinates are J(-3,18) and T(7,-10). Show all work

nignag [31]

Given two points (x₁,y₁) and (x₂,y₂), the midpoint of the segment will be:
( (x₁+x₂) / 2 , (y₁+y₂)/2 ).
In this case:
J(-3,18)
T(7,-10)

The midpoint will be:
( (-3+7)/2 , (18-10)/2 )=(4/2 , 8/2)=(2, 4).

Answer: the midpoint of segment JT is (2,4)
