Answer:

Step-by-step explanation:

The translation suggests only a change in location and perhaps a change of scale, but the angles remain the same.

So, A is false because ∠D' would be simply 74° like the original.

C is false because ∠F' would be 59° like the original

D is false because D'E' would correspond to DE and not DF.

Answer:

Step-by-step explanation:

(0, -1) (3,3)

(3 + 1)/(3 - 0) = 4/3

y + 1 = 4/3(x - 0)

y + 1 = 4/3x - 0

y = 4/3x - 1

Answer:

Binomial; \mu p=87.5, \sigma p=7.542

Step-by-step explanation:

a distribution is said be a binomial distribution iff

The probability of success of that event( let it be p) is same for every trial
each trial should have 2 outcome : p or (1-p) i.e, success or failure only.
there are fixed number of trials (n)
the trials are independent

here, the trials are obviously independent ( because, one person's debt doesn't influence the other person's)

here n=250

the probability of success(0.35) is same for every trial

(35/100=0.35 is the required p here)

$\mu_{p} =n*p=250*\frac{35}{100} =250*0.35=87.5$

[since, the formula for $\mu _{p} =n*p$ ]

$\sigma _{p} =\sqrt{n*(p)*(1-p)} = \sqrt{250*0.35*(1-0.35)} = 7.542 ( approximately)$

[since, the formula for [tex]\sigma _{p} =\sqrt{n*(p)*(1-p)}

therefore, it is Binomial; \mu p=87.5, \sigma p=7.542

The circumference of a circle is 11 pi inches.

ser-zykov [4K]

9514 1404 393

Answer:

30.25π square inches

Step-by-step explanation:

You can use the formula for area in terms of circumference:

A = C²/(4π)

A = (11π)²/(4π) = (121/4)π = 30.25π . . . square inches

_____

You may be expected to find the radius first:

C = 2πr ⇒ r = C/(2π) = 11π/(2π) = 5.5 . . . inches

Then use the area formula:

A = πr² = π(5.5 in)² = 30.25π in²
