Answer:

The value is  [tex]n =29 \ employees [/tex]

Step-by-step explanation:

Generally the number of employee to survey(sample size) is mathematically represented as

       [tex]n = [ \frac{z *  \sigma }{E} ]^2[/tex]

Here E is the margin of error which is given as E = 47

So substituting 1.645 for z and   155 for  [tex]  \sigma[/tex]

     [tex]n = [ \frac{1.645 *  155 }{47} ]^2[/tex]

=>    [tex]n =29 \ employees [/tex]

Step-by-step explanation:

Answer:

1421235

Step-by-step explanation:

2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 x 45 = 1421235

2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 ➗ 45 = 701.844444444

If its multiplication the answer is = 1421235

If division the answer is = 701.844444444 (calculator) or 701 r 38 (my brain)

Question: 11.23 x 10 to the power of 5, the answer is 11.2300000.

Explanation: multiple 10 x 10 x 10 x 10 x 10 = 10,000, then multiple 11.23 x 10,000 = 112300000, add the decimal places = 11.2300000.

Question: 11/20 a repeating or terminating decimal,

Answer: is terminating.

Question: 7 * 73 + 43, the answer is 554.

Explanation: multiple 7 x 73 = 511 + 43 = 554. If division then divide 7 into 73 = 10.4285714286 + 43 = 53.4285714286 (calculator answer). 7 into 73 = 1 r 3 = 1.3 + 43 = 44.3 or 44 r 3 (my brain answer).

Answer:

b = 40

Step-by-step explanation:

-b/4 = - 10              Multiply both sides by 4

-b/4 * 4 = - 10 * 4

- b = - 40               Multiply both sides by -1

(-1) * (-b) = (-40)(-1)

b = 40

Answer:

500 gallons

Step-by-step explanation:

25/5=5 5*100=500

Answer:

You need 500 gallons for 25 fish

Answer: 24

Step-by-step explanation:

Chocolate bars sold in first week:

= 2x² + 3x − 1

where x = 2

= 2x² + 3x − 1

= 2(2)² + 3(2) − 1

= (2×4) + 6 - 1

= 8 + 6 - 1

= 13

Second week

= 3x² - 2x + 3

= 3x² - 2x + 3

= 3(2)² - 2(2) + 3

= 12 - 4 + 3

= 11

Total chocolate sold = 13 + 11 = 24

2(x+5)>8

Step-by-step explanation:

x>-1

hope that's it

Hi!

I can help you with joy!

No worries, we can solve this inequality easily. :)

First of all, let's use the Distributive Property and distribute 2:

[tex]\rm{2(x+5)>8[/tex]

[tex]\rm{2x+10>8[/tex]

Now, move 10 to the right, using the opposite operation:

[tex]\rm{2x>8-10[/tex]

Subtract:

[tex]\rm{2x>-2[/tex]

Final Step: Divide both sides by 2.

[tex]\rm{x>-1[/tex] (Answer)

Hope it helps!

Answer:

The costs of the two plans would be equal with 200 minutes.

Step-by-step explanation:

From the information given, you can write the following:

18+0.08x=10+0.12x, where x is the number of minutes of calls

Then, you can solve for x:

18-10=0.12x-0.08x

8=0.04x

x=8/0.04

x=200

According to this, the answer is that the costs of the two plans would be equal with 200 minutes.

Answer:

move 5m over the sign so it is like this m-5m>-4 subract it will be-4m>-4 divide both sides by-4 m=1 negative divided by a negative is a positive

the answer is m<1

I subtracted 5 from both sides to get m-5m>-4

I simplified it to -4m>-4

divided both sides by -4 and got m<1 as the answer

Answer:

for A=[tex]\frac{7b-7}{6}[/tex] and for B=[tex]\frac{6a+7}{7}[/tex]

Step-by-step explanation:

For A

[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]

[tex]6a-3+3=7b-10+3[/tex]

[tex]6a=7b-7[/tex]

[tex]\frac{6a}{6}=\frac{7b}{6}-\frac{7}{6}[/tex]

[tex]a=\frac{7b-7}{6}[/tex]

For B

[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]

[tex]7b-10=\left(6a-3\right)[/tex]

[tex]7b-10=6a-3[/tex]

[tex]7b-10+10=6a-3+10[/tex]

[tex]7b=6a+7[/tex]

[tex]\frac{7b}{7}=\frac{6a}{7}+\frac{7}{7}[/tex]

[tex]b=\frac{6a+7}{7}[/tex]

Answer:

1,104 points

Step-by-step explanation:

First I figured out how many seconds it took to finish the game (132)

Then I figured out how many points he got by multiplying 30x50=1,500

After that, I multiplied 3 and the number of seconds that it took to finish the game (3x132) and that gave me the answer of 1,104 points
