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,

\begin{gathered} \frac{XY}{CD}=\frac{YZ}{DE} \\  \\ \frac{XY}{1.2}=\frac{4}{3.2} \\  \\ XY=\frac{4}{3.2}\cdot1.2=1.5\operatorname{cm} \end{gathered}

So, the length of XY = 1.5 cm

In the diagram, JOK and MON are straight lines. Angle NOP and Angle NOQ are complimentary angles. Calculate the value of x - y.
Pepsi [2]

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

A sample with mean of 85 and SD of 12 is transformed into z-scores. After the transformation, what are the values for the mean a
MrRa [10]

Answer:

The value remain unchanged.

Step-by-step explanation:

By Z score, we mean:

Z = \frac{x-\mu}{\sigma}, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,

Z =  \frac{85 - 0}{12} = 85/12 = 7.083333.

NB: We assume that mean and standard deviation are in the same units.

7/12+1/3 show your work and how you got your answer and you do all that and don’t scam me I will give branlist
Yanka [14]

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! :)
