MA_775_DIABLO [31]3 years ago
4 0

Mean: $620, Mode: $600

Let's sort the rank stats.

First quartile: $580

Median: $610

Third quartile: $645

85th percentile: $685

OK, we're ready.  What happened to a and b?

c. $645 is the third quartile, 75th percentile.  That means 25% of the salaries are higher.

Answer: 25%

d.  $685 is the 85th percentile, 15% greater.

Answer: 15%

e.  The mean is the sum of all the salaries divided by the count.  

Mean = Sum / Count

So the sum is the count times the mean,

Sum = Count × Mean  = 100 × $620 = $62,000

Big payroll.

Answer: $62,000

The figure below shows rectangle ABCD.
kipiarov [429]

Answer: We can find out the missing statement with help of below explanation.

Step-by-step explanation:

We have a rectangle ABCD with diagonals AC and BD ( shown in given figure.)

We have to prove: Diagonals AC and BD bisect each other.

In triangles, AED and BEC.

\angle ADB \cong \angle CBD ( By alternative angle theorem)

AD\cong BC ( Because ABCD is a rectangle)

\angle CAD\cong \angle ACB  ( By alternative angle theorem)

By ASA postulate,\triangle AED\cong \triangle BEC

By CPCTC, BE\cong ED and CE\cong EA

⇒ BE= ED and CE=EA

By the definition of bisector, AC and BD bisect each other.

Help!!! Will give brainliest to correct answer.....
zlopas [31]
I believe the answer is C.

93.53 - 21.41 = 72.12

If you simplify C, its answer becomes equivalent to the answer of the original problem:

(90 - 20) + (3 - 1) + (0.5 - 0.4) + (0.03 - 0.01)

70 + 2 + 0.1 + 0.02

72.12

Help asap will give brainliest!!!!
GarryVolchara [31]

Answer:

C

Step-by-step explanation:

ley y = f(x) and rearrange making x the subject

y = \frac{1}{x+5} - 1 ( add 1 to both sides )

y + 1 = \frac{1}{x+5} ( multiply both sides by (x + 5)

(y + 1)(x + 5) = 1 ← expand factors using FOIL

xy + 5y + x + 5 = 1 , that is

xy + x + 5y + 5 = 1 ( factor first/second and third/fourth terms on left side )

x(y + 1) + 5(y + 1) = 1 ← factor out (y + 1) from each term on left side

(y + 1)(x + 5) = 1 ( divide both sides by (y + 1) )

x + 5 = \frac{1}{y+1} ( subtract 5 from both sides )

x = \frac{1}{y+1} - 5

Change y back into terms of x with x = f^{-1} (x) , then

f^{-1} (x) = \frac{1}{x+1} - 5 where x ≠ - 1

a card is drawn at random from a standard 52 card deck has a 1/13 chance of being at 8. What is the probability of the car not b
Free_Kalibri [48]

Answer:

12/13

Step-by-step explanation:

There are 52 cards in the deck

4 are aces

That leaves 52-4  or 48 that are not aces

P(not an aces) = cards that are not aces / total

                        = 48/52

                       =12/13

An electrical power company is looking to expand into a new market. Before they commit to supplying the new area with electricit
TiliK225 [7]

Answer:

atleast 385

Step-by-step explanation:

Given that an electrical power company is looking to expand into a new market. Before they commit to supplying the new area with electricity, they would like know the mean daily power usage for homes there.

Population std deviation = \sigma = 50

Sample size =n

STd error of sample mean = \frac{50}{\sqrt{n} }

Margin of error for 95% would be Critical value ( std error)

Here since population std dev is known we can use Z critical value= 1.96

1.96*\frac{50}{\sqrt{n} }19.6^2\\n>384.16

Sample size should be atleast 385
