Answer:
0.3085,0.2417,0.0045
Step-by-step explanation:
Given that X, the amount of money spent at shopping centers between 4 P.M. and 6 P.M. on Sundays has a normal distribution with mean $85 and with a standard deviation of $20.
X is N(85, 20)
To convert into std normal variate we use the following formula
a) the probability that he has spent more than $95 at the mall
=
b. the probability that he has spent between $95 and $115 at the mall
=
c. If two shoppers are randomly selected, what is the probability that both shoppers have spent more than $115 at the mall
=product of two probabilities since independent
= 
Since the length and width of the pictures are given in cm, let's convert all lengths to cm.
Remember that 1 m = 100 cm
3.6 m = 360 cm
1.8 m = 180 cm
The area of a rectangle is A = LW. The area of the board is
A = LW = 360 cm * 180 cm = 64,800 cm^2
The area of each picture is 6 cm * 6 cm = 36 cm^2
To see how many pictures fit in the board, we divide the area of the board by the area of one picture.
(64,800 cm^2)/(36 cm^2) = 1,800
Answer: 1,800 pictures

Answer:
Step-by-step explanation:
3. Find the measure of ZC. 4. Find the value of x. 85°. 40+36 t C +90=180 ... 2x+ 85++35=360/35. 3x + 120 360. 3x=240. X=80. A. B. 5. Two angles are ... If 2 parallel lines are cut by a ... 4. Find y if m27 = 68 and m26 = 3y - 2. If 2. 11 lines are cut by a transversal, ... An auxiliary Line is sometimes useful when solving for.
Given: ABCD ∥gram,
BK ⊥ AD , AB ⊥ BD
AB=6, AK=3
Find: m∠A, BK
To proof
as given BK ⊥ AD
thus ΔABK is a right triangle.
thus by using the pythagoras theorem
we have
AB² = BK² + AK²
BK² = AB ²- AK²
= 6² - 3²
= 36 - 9
= 27
Hence
BK = <u>
unit</u>
Now find the value m∠A
by using the trignometric function
FORMULA
cosA = 
cosA = 
= 
m∠A = 60°
hence proved
