Answer:
435 in.²
Step-by-step explanation:
Surface area of the square pyramid = area of the square base + ½(Perimeter of base)(slant height)
Area of base = s²
s = 15 in
Area = 15² = 225 in²
Perimeter of the base = 4(15) = 60 in
Slant height = 7 in
Surface Area = 225 + ½(60)(7)
= 435 in.²

Emergency rooms have reason to suspect that visits increase on the weekends. A recent report indicates that Monday through Thursday represent 10% per day of the weekly total visits while Friday accounts for 15%, Saturday 25% and Sunday 20%. If your ER has the following pattern, Monday, 120, Tuesday, 130, Wednesday 110, Thursday 95, Friday 160, Saturday 280 and Sunday 105.
Does your facility have the same pattern as the recent report at the 10% level?
1. Yes
2. No
Answers
Answer:
i think i am pretty sure its a yes
No, the facility dose not have the exact pattern as the recent report at the 10% level.

Given that the observed frequency and expected proportion exists given
For Monday
expected frequency = proportion [tex]*[/tex] frequency = 0.1 [tex]*[/tex] 1000 = 100
(O-E)²/E. = ( 120 - 100 )² / 100 = 4.0.
observed frequency (O), expected frequency (E)
For Tuesday
E = 0.1 [tex]*[/tex] 1000 = 100
(O-E)²/E = ( 130 - 100 )² / 100 = 9.0
For Wednesday through Sunday
Then perform Chi-squared test
X² = Σ(O-E)²/E = 63.642
∝ = 0.1
df = 6
hence P-value = 0.000 ( = chi sq dist rt(test-stat,df)
since P-value < ∝ ; we will fail to reject Ha hence we reject [tex]$H_{0}[/tex].

if y=12 and x=89, then what is the value of z?
Answers
Answer:
z = 166°
Step-by-step explanation:
Given:
x = 89
y = 12
An angle with its vertex in a circle = ½(intercepted arcs)
Thus:
x = ½(y + z)
Substitute
89 = ½(12 + z)
Multiply both sides by 2
2(89) = 12 + z
178 = 12 + z
178 - 12 = z
z = 166°

The given figure is an octagon. The sum of interior angles in an octagon is 1080. Thus, one can form an equation, add up all of the angle measures, and set the equation equal to 1080. Then simplify and use inverse operations to find the value of the parameter (t).
(150) + (3t + 34) + (5t) + (5t) + (3t + 37) + (7t - 49) + (5t - 16) + (5t) = 1080
Simplify,
33t + 156 = 1080
Inverse operations,
33t + 156 = 1080
-156 -156
33t = 924

t = 28
Omar the tent maker wishes to support a 13.4-ft tent wall by attaching 25-ft cable to the top of it, and then anchoring the cable to the ground. If the cable is pulled tight, how far from the base of the tent will it be anchored?
Answers
Answer:
21.11 ft
Step-by-step explanation:
This question would be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
13.4² + b² = 25²
179.56 + b² = 625
b² = 625 - 179.56
b = 445.44
find the square root of 445.44
b = 21.11 ft

concrete cost for the pillar?
If necessary, refer to the list of cometry formulas
For your calculations, do not round any intermediate stops, and use the it button on the ALEKS calculator Round your answer to the nearest cent.
Answers
Answer:
The cost of concrete for the pillar would be $ 15,260.40.
Step-by-step explanation:
Given that a concrete pillar has the shape of a cylinder and it has a diameter of 6 meters and a height of 5 meters, if concrete costs $ 108 per cubic meter, to determine how much did the concrete cost for the pillar the following calculation must be done, knowing that the volume of a cylinder is calculated with the following formula = πxr²xh:
3.14 x (6/2) ² x 5 = X
3.14 x 3² x 5 = X
3.14 x 9 x 5 = X
3.14 x 45 = X
141.3 = X
141.3 x 108 = X
15,260.4 = X
Therefore, the cost of concrete for the pillar would be $ 15,260.40.

Brazil's government estimates that farmers cut down 10,590 square miles (27,430 square kilometers) of rain forest. That is an area larger than Vermont, and it shows an increase from the deforestation of the previous year. In fact, the 2004 figure is nearly that of 1995, in which the Amazon lost a record 11,229 square miles (29,080 square kilometers) of trees.
