Write The Equation on the line.​

Answer:

Actual Mean = 43

Step-by-step explanation:

Given Mean = 38

No of observations = 9

we know,

Mean = Sum / N

38 = Sum/ 9

Sum = 38 x 9 = 342

Since the observation 27 was mistakenly taken instead of 72, we subtract 27 from the sum and add 72.

New sum = 342 - 27 = 315 again, 315 + 72 = 387

The no. of observations stays the same.

Actual mean = New Sum / N

= 387/9

=43

Step-by-step explanation:

arithmetic mean =38

n=9

mean=sum/n

sum=mean×n=38×9=342

mistakenly observation 27 is taken instead of 72

new sum becomes =342+72-27=387

now

new mean =new sum/n=387/9=43

the actual mean of the data is 43.

the first one is correct

i can prove it but its hard on this app and it has a long solution

you can prove it by Thales law

hope this helps

Answer:

a. 405/4

b. 1/32

Step-by-step explanation:

a. (5x8 + 5) / 8 x 18

= 45/8 x 18

= 405/4

b. 3/8 ÷ 12

= 3/8 x 1/12

= 1/32

Answer:

-73

Step-by-step explanation:

if f is 73

and they made f negative, they just made 73 negative too.

i don't know if there is more in that expression

Equality Properties

Step-by-step explanation:

Step 1: Define

3 - 4r ≥ 15

Step 2: Solve for r

Step 3: Compare

This is true. -3 is less than or equal to -3.

Answer:

I think 15 I dont see it in the options but im going to explain my answer

Step-by-step explanation:

4 + 4 = 8, 13 - 8 = 5 x 6 = 30 divided by 2 is 15

SO 8 x 13 = 104 - 15 = 89 so therefore its 89!

Answer:

3/2 is greater than 1

Step-by-step explanation:

A little trick to immediately know if a number is more or less than when it involves fractions versus whole numbers is that improper fractions will always be greater than 1.

If you want to confirm this, dividing 3/2 equals 1.5, ergo 1.5 > 1.

In essence, improper fractions will always represent a number greater than one contrasted to proper fractions because if you put it on a perspective (let's say you have 13 pie slices but you only needed 12, that means there is a pie slice that's extra that makes it greater than the original pie slices).

Answer:

Common-size percent for cash = 5.73 % (Approx.)

Step-by-step explanation:

Given:

Total cash = $26,200

Total assets = $457,000

Total equity = $156,630

Find:

Common-size percent for cash

Computation:

Common-size percent for cash = [Total cash/Total assets]100

Common-size percent for cash = [26,200/457,000]100

Common-size percent for cash = 5.73 % (Approx.)

Answer:

1/5

Step-by-step explanation:

Chance is also referred to as probability

probability = Number of event/Total samples space

If there are 6 black socks,8 white socks,2 red socks, and 4 blue socks in a drawer, the total number of socks will be the sample space

Sample space = 6 + 8 + 2 + 4

Sample space = 20socks

Total number of blue socks is the event

Number of event = 4 blue socks

Chance that the socks is blue = n(E)/n(S)

Chance that the socks is blue = 4/20

Chance that the socks is blue = 1/5
