Answer:
D
Step-by-step explanation:
first you have to do 6 times 3 and get 18 then you need to add 3 to that then divided that by 2 then you get your answer
Answer:
Step-by-step explanation:
Considering the given triangle VRN, to determine VR, we would apply the sine rule. It is expressed as
a/SinA = b/SinB = c/SinC
Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes
VR/SinN = VN/SinR = RN/SinV
Therefore
VR/Sin 75 = 22/Sin 39
Cross multiplying, it becomes
VRSin39 = 22Sin75
0.629VR = 22 × 0.966
0.629VR = 21.252
VR = 21.252/0.629
VR = 33.8 m
Answer: 0.8531
Step-by-step explanation:
Let x be the random variable that represents the readings on scientific thermometers .
Given : The readings on scientific thermometers are normally distributed,
Population mean : 
Standard deviation : 
Z-score : 
Now, the z-value corresponding to -1.05 : 
P-value = 
Hence, the probability of the reading greater than -1.05 in degrees Celsius.= 0.8531
3(x-1) = 2x - y
3x-3 = 2x-y
3x-2x+y = 3
x + y = 3 ----> (1)
2(x+y) = 3+3y
2x + 2y = 3 + 3y
2x + 2y - 3y = 3
2x - y = 3 -----> (2)
make equation (1) and (2) together
x + y + 2x - y = 3+3
3x = 6
x = 2
now make x = 2 in equation (1)
x + y = 3
2 + y = 3
y = 3-2
y = 1
(x,y) = (2,1)
