Answer:

-9/5 or -1.8

Step-by-step explanation:

3x+27=-2x+18 add 2x to both side

5x+27=18 minus 27 from both side

5x=-9 divide 5

x=-9/5, in decimal form=-1.8

Answer:-9/5

Step-by-step explanation:

3x + 27 = -2x + 18

    -27           -27

-3x = -2x - 9

+2x   +2x

5x = -9

5x/5 = -9/5

x= -9/5

Answer:

b) 1.75       c) 0.875

Step-by-step explanation:

lt is given that a couple plans to have children until they get a girl, but they agree that they will not have more than three children even if all are boys.

a) The possible combination for the number of children  that a couple might have  :

  X             1st girl      1st boy, 2nd girl       1st ,2nd boys,3rd girl    1,2,3rd boys Probability-   0.5                 0.25                        0.125                           0.125

b) Expected number of children   :

   1(0.5) + 2 ( 0.25 ) + 3 ( 0.125)  + 3( 0.125)

   =  1+ 0.75

   = 1.75

c) Expected number of boys :

     0 x 0.5  + 1 x 0.25  + 2 x 0.125 + 3 x 0.125

    =    0.875

Answer:

the answer is 225cm3

Answer: See explanation

Step-by-step explanation:

1. The population in a research are the group of people that the research study carried out by a researcher will affect. In this case, the population will be 3456.

2. The sample study are those that took part in the research. In this case, the sample study will be 104 since they're the ones that took part and returned the questionnaires.

Answer:

B: $90.

Step-by-step explanation:

The expression for this problem can be represented as

Total Cost = $44 + 2c

Since one chair costs $23, the total cost would be:

Total Cost = $44 + 2($23)

2 × 23 = 46

Total Cost = $44 + $46 = $90

The total cost is $90, choice B.

Team of volunteers help to pack meals for charity. They can pack 125 meals in an hour. How many meals would be packed in 20 hours?

Answer:

Step-by-step explanation:

Your question isn't well written but I guess that you want to calculate the difference that exist beteeeh11 hour and 10 hour 25 minute. Thus will be:

= 11 - 10:25

= 35 minutes

It should be noted that 60 minutes = 1 hour.

Answer:

Step-by-step explanation:

Answer:

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228

Step-by-step explanation:

Step(i):-

Given mean of the Population = 500

Given standard deviation of the Population = 50

Let 'X' be the random variable in normal distribution

Given  X = 600

[tex]Z = \frac{x-mean}{S.D} = \frac{600-500}{50} = \frac{100}{50} =2[/tex]

Step(ii):-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = P(z≥2)

                  = 0.5 - A(2)

                 = 0.5 -0.4772

                = 0.0228

Final answer:-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228

answer is C

Answer:

Step-by-step explanation:

in order to simplify the form, you will remove the parenthesis first,

2w^3+4w^2+5+3W^3+W^2+4W=

=5W^3+5W^2+4W+5

CHOICE C

Answer:

10

Step-by-step explanation:

h(x) = 4 - 2x

h(-3) = 4 - 2*(-3)

       = 4 + 6

      = 10

Hey there!

The answer is no, they would not return to the original price of $200.

This is because when you decrease 200 by 20%, you get 160. Then, if you increase 160 by 20%, you get 192. This is because 20% of 200 and 20% of 160 is different.

Hope this helps! Have a great day, and good luck on your assignment!

Step-by-step explanation:

calculator, dude.

Answer:

Its 3,464 *smh

If you had 99 barrels of oil, then multiplied it why 36, how much would u have?

Answer - 3,464

Answer:

in the triangle ACB

∠ACB+90+34=180-----> ∠ACB=180-(90+34)----> ∠ACB=56°

∠ACD and ∠ACB-----> are supplementary angles

so

∠ACD+∠ACB=180-----> ∠ACD=180-56----> 124°------> x=124°

the answer Part 1) is x=124°

Part 2)

∠ACB+∠BCF+80=180-----> ∠BCF=180-(∠ACB+80)---> 180-(56+80)

∠BCF=180-136----> 44°-----> y=44°

the answer Part 2) is y=44°

Answer:

16 2/3%

Step-by-step explanation:

rate of return is the profit (1750 - 1500) over the original investment

Answer: A. Side a is 26 inches long, side b is 20 inches long, and side c is 10.

Step-by-step explanation:

Scale factor for drawing = 2:1

Dimensions of drawing :  10 in, 5 in, 13 in

Dimension of object = Scale factor x Dimension of drawing

Sides of object:

2 x 10 in =20 in   [b]

2 x 5 in = 10 in  [c]

2 x 13 in = 26 in.  [a]

Hence, the correct option is

A. Side a is 26 inches long, side b is 20 inches long, and side c is 10.

Answer:

Side a is 2.5 inches long, side b is 5 inches long and side c is 6.5 inches long.
