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
The best estimate of the number of times Amber would pull out a New York quarter is 120.
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

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.
Answer:
The Index
Step-by-step explanation:
A radical expression is composed of three parts:
The Radicand - The number or term under the horizontal bar of the radical symbol.
Radical Symbol - The Radical Symbol √
Index - The number near the "check" part of the radical symbol.
In the given expression, 4 is the index. We are supposed to find the 4th root of x to the third power.
Hope this helps.
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
