Answer:

A. The standard deviation is np(1 - p).

Step-by-step explanation:

The variance of the number of successes/failures is measured by (σ2x) is n * P * ( 1 - P ).

The standard deviation (σx) is square root of [ n * P * ( 1 - P ) ]

The mean is np.

Lilit [14]

Answer:

Firstly you need to put the equation in form of. y =ax+b

Let us do it

We have

2x-2y=18

-2y=18-2x

-y=(18) /2 - (2x)/2

-y =9-x

Mutiply by - to remove it beside y

Y=-9+x

Which is y=x-9

Slope =a=1

Yintercept=b=-9

(6,-13);y=2/9x- 5 write it in slope-intercept form
Amiraneli [1.4K]

Answer:

y=2/9x-14.33

Step-by-step explanation:

y=2/9x- 5

then y=2/9x+b

enter points (6,-13)

-13=12/9+b

-13-12/9=b

-14.33=b

y=2/9x-14.33

In the triangles, XY = MP and YZ = PN. Triangles Y X Z and P M N are shown. The length of side X Z is 23 inches. The length of s
ziro4ka [17]

Answer:

m\angle Y = 85\°

Step-by-step explanation:

In Triangles YXZ and PMN

XY \cong MP\\YZ \cong PN

Since the third side of  triangle subtended by two congruent sides will always be congruent, the two triangles are congruent by SSS congruence theorem.

Therefore:\triangle XYZ \cong \triangle MPN\\

If the measure of angle P = 85°

Since P and Y are in the same positions(as seen in the diagram) in the two triangles respectively, the measure of angle Y is also 85 degrees.

What is the value of 100?
Nesterboy [21]

Answer:

10

Step-by-step explanation:

Means back the numbers into multiples of several small numbers

Like:; 1. We take LCM of 40

Just break into multiples of small number

40= 2×2×2×5

2. We take LCM of 50

50= 5×5×2

So LCM for 100 is 2×2×5×5

after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)

Then write the the single number in place of two multipled numbers

Like:; 2×2 is written as 2 // 3×3 is written as 3

So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)

write pairs in single number 2×5

And so we get 2×5=10

So we find root of 100 that is 10
