I found the table that contains the following data:
25 times:
Column No.      1     2     3    4    5    Total

New York         3     2     2    1    2     10
Connecticut      1     1     1    2    0       5
Pennsylvania    1     1     1    1    1       5
Rhode Island    0     1     1    1     2       5

New York: 10/25 or 2/5
Connecticut: 5/25 or 1/5
Pennsylvania: 5/25 or 1/5
Rhode Island: 5/25 or 1/5

300 times * 2/5 = 120 times for New York

Please help please please
Marina CMI [18]

Answer:

C. y = 2x + 8

Step-by-step explanation:

✔️First, find the slope of the line that goes through points (-2, 4) and (6, 20):

Slope (m) = ∆y/∆x = (20 - 4) / (6 - (-2))

Slope (m) = 16/8

m = 2

✔️Find the y-intercept (b):

To do this, substitute (x, y) = (6, 20) and m = 2 into y = mx + b

Thus:

20 = 2(6) + b

20 = 12 + b

20 - 12 = b

8 = b

b = 8

✔️Write the equation by substituting m = 2 and b = 8 into y = mx + b

Thus:

y = 2x + 8

How do I work this out
alukav5142 [94]

9514 1404 393

Answer:

  no, it is good for 2 weeks (almost 3)

Step-by-step explanation:

The volume of the pool is ...

  V = LWH

  V = (20 m)(8 m)(1.8 m) = 288 m³

Then the amount of chlorine powder needed for 1 week is ...

  (300 g/(50 m³)) × (288 m³) = 1728 g

A box of 5000 g holds enough chlorine for ...

  (5000 g)/(1728 g/treatment) = 2.89 treatments

A box of chlorine powder is enough for 2 weeks, not 4.

An architect presents a 3 inch wide by 4 inch deep by 3 inch tall model of a new central campus dorm . If the final building fou
IRISSAK [1]

Answer:

Building depth = 168 ft

Step-by-step explanation:

we must find the relationship (scale) of the model with respect to the building .

wide-m (model) = 3 in

deep-m(model) = 4 in

wide-b (building) = 126 feet

deep-b(building) = x

the measures must be standardized

let's convert feet to inches

12 in      →   1 feet

3   in     →   ?,   then

3 in → 0.25 feet and 4 in → 1/3 feet

now deep-m = x

x=\frac{(1/3)ft*126ft}{0.25ft}=168 ft
