Answer:
Its 88
Step-by-step explanation:
Given;
ABCDE is similar to VWXYZ
so, the corresponding segments are proportional
We need to find the length of XY
XY is corresponding to CD
CD = 1.2 cm
Finding another two corresponding sides
DE = 3.2 cm , YZ = 4 cm
so,
So, the length of XY = 1.5 cm
Answer:
x - y = 118
Step-by-step explanation:
Since ∠ NOP and ∠ NOQ are complimentary then ∠ POQ = 90°
Since JOK is a straight line then
∠ JOP + ∠ POQ + ∠ QOK = 180 , that is
76 + 90 + y = 180
166 + y = 180 ( subtract 166 from both sides )
y = 14
Since MON is a straight line then
∠ MOK + ∠ KOQ + ∠ QON = 180, that is
x + 14 + 34 = 180
x + 48 = 180 ( subtract 48 from both sides )
x = 132
Thus
x - y = 132 - 14 = 118
Answer:
The value remain unchanged.
Step-by-step explanation:
By Z score, we mean:
Z = 
, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,
Z = 
= 85/12 = 7.083333.
NB: We assume that mean and standard deviation are in the same units.
Answer: 11/12
Step-by-step explanation:
7/12 and 1/3 don’t have the same denominator, so you can’t just add them right away. You have to give them the same bottom number. 1/3 = 4/12, so you can do it like this:
7/12 + 4/12 = 11/12
11/12 is in simplest form, so that should be correct! Hope this helps! :)
