it is 10 divided by 18 which is 0.5
Answer:
positive ! the answer would be 97
Step-by-step explanation:
since you are subtracting a negative ( - - ) that automatically makes the answer positive. anytime you see subtraction sign next to a negative sign, you add !! (94 + 3 = 97! )
No solutions
Set equations equal to each other
-3.5x - 3.5 = -3.5x + 3.5
The -3.5x on both sides of the equation cancels out, leaving
-3.5 = 3.5
But -3.5 does NOT equal 3.5, so the solution to the system of equations is false. This means that there are no solutions.
For a normal distribution with mean 54 and standard deviation 5 95.4% of them fall between 44 and 64
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
Therefore., from the normal distribution table:
P(44<x<64) = P(-2< z < 2) = P(z < 2) - P(z < -2) = 0.9772 - 0.0228 = 0.9544
Hence, About 95.4% of them fall between 44 and 64.

Answer:
Step-by-step explanation:
Looking at the diagram,
Line DT is parallel to line line BM, therefore, triangle DHT is similar to triangle BHM. This means that
DH/DB = TH/MH
DH = 15 + 6 = 21
TH = 9 + x
Therefore
(9 + x)/21 = 9/6
Cross multiplying, it becomes
6(9 + x) = 21 × 9 = 189
54 + 6x = 189
Subtracting 54 from the left hand side and the right hand side of the equation, it becomes
6x + 54 - 54 = 189 - 54
6x = 135
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 135/6
x = 22.5
