<h2>Answer:</h2>

City B is more predictable because there is less variability.

<h2>Step-by-step explanation:</h2>

Smaller variability= numbers closer together

When the numbers are closer together, the data is more consistent making it easier to predict.

Greater variability= numbers father apart

When the numbers are farther apart, the data is less consistent and very hard to predict.

<h2><u>Hope that helped! ;p</u></h2>

The price of a shirt is marked down from $12.50 to $10,00. What is the percent decrease of the shirt?

choli [55]

Answer: 20%.

Step-by-step explanation:

Given, The price of a shirt is marked down from $12.50 to $10.00.

Previous price = $12.50

New price = $10.00

Change in price = Previous price - New price

= $12.50 - $10.00

= $2.50

Now, the percent decrease of the shirt = $\dfrac{\text{Change in price}}{\text{Prevoius price}}\times100$

$=\dfrac{2.50}{12.50}\times100\\\\=20\%$

Hence, the percent decrease of the shirt = 20%.

The area of circle B is 121 times greater than the area of circle A. The radius of circle B is 44. What is the radius of circle

xxMikexx [17]

<em>Formula:</em>
$\bigg( \dfrac{radius_1}{radius_2} \bigg)^2 = \dfrac{area_1}{area_2}$

<em>Plug in the values:</em>
$\bigg( \dfrac{r}{44} \bigg)^2 = \dfrac{1}{121}$

<em>Simplify LHS:</em>
$\dfrac{r^2}{1936} = \dfrac{1}{121}$

<em>Multiply by 1936 on both sides:</em>
$r^2 = \dfrac{1936}{121}
$

<em>Simplify RHS:</em>
$r^2 = 16$

<em>Square root both sides:</em>
$r = 4$

Answer: The radius is 4 units. (Answer B)

Please help me out with this problem!!!

Ronch [10]

Answer:

y = 3x - 2

Step-by-step explanation:

The equation is linear and expressed in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Given (0, - 2 ) then c = - 2

Calculate the multiplier using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1,1) ← 2 ordered pairs from the table

m = $\frac{1+2}{1-0}$ = 3, hence

y = 3x - 2 ← equation relating x and y
