Mean of 72, 75, 78, 72, 73

Answer:

(i) 4000

(ii) $5.00

Step-by-step explanation:

Let no. of shares of Company A be X

Let share price of Company B on Day 7 be $y

Share price of Company B on Day 12 = $(y-0.50)

(i)

Consider Day 7:

4.60x - 2000y = 7400................ (1)

Consider Day 12:

4.80x - 5000(y-0.50) = -5800

4.80x - 5000y + 2500 = -5800

4.80x - 5000y = -8300............... (2)

(1)*2.5:

11.5x - 5000y = 18500................. (3)

(3)-(2):

11.5x - 4.80x - 5000y + 5000y = 18500 + 8300

6.70x = 26800

x = 4000

(ii)

Sub. x = 4000 into (1):

4.60(4000) - 2000y = 7400

-2000y = 7400 - 18400

-2000y = -11000

y = 5.5

Share price of Company B on Day 12

= 5.50 - 0.50

= $5.00

9. First Five terms

If n=0. Then,

[tex] \frac{4(0) - 5}{2}[/tex]

[tex] \frac{0 - 5}{2} = \frac{ - 5}{2} [/tex]

If n=1. Then,

[tex] \frac{4(1) - 5}{2} [/tex]

[tex] \frac{4 - 5}{2} = \frac{ - 1}{2} [/tex]

If n=2. Then,

[tex] \frac{4(2) - 5}{2} [/tex]

[tex] \frac{8 - 5}{2} = \frac{3}{2} [/tex]

If n=3. Then,

[tex] \frac{4(3) - 5}{2} [/tex]

[tex] \frac{12 - 5}{2} = \frac{7}{2} [/tex]

If n=4. Then,

[tex] \frac{4(4) - 5}{2} [/tex]

[tex] \frac{16 - 5}{2} = \frac{11}{2} [/tex]

If n=5. Then,

[tex] \frac{4(5) - 5}{2} [/tex]

[tex] \frac{20 - 5}{2} = \frac{15}{2} [/tex]

If n=6. Then,

[tex] \frac{4(6) - 5}{2} [/tex]

[tex] \frac{24 - 5}{2} = \frac{19}{2} [/tex]

Answer:2.4 or 12/5

Answer:

After solving the problem, the answer is x>1/2. However I do not see the answer choice provided so I do not know the answer to the question

Step-by-step explanation:

Answer:

You need the distance of all four sides so that is:

2 * (5y +1) + 2 * (2y -3) which equals

10y + 2 + 4y -6 and that equals

14y -4

Step-by-step explanation:

Hello there, this is how we will solve your problem.\

here is the equation you gave us.

[tex]{\huge{\boxed{\mathbb{EQUATION}}}[/tex]

[tex]\begin{bmatrix}-5x+y=-3\\ 3x-8y=24\end{bmatrix}[/tex]

we can isolate [tex]x[/tex] and say [tex]x=\frac{-3-y}{5}[/tex]

Now here is our equation, [tex]\begin{bmatrix}3\left(-\frac{-3-y}{5}\right)-8y=24\end{bmatrix}[/tex] After we simplify it we get [tex]\begin{bmatrix}\frac{9-37y}{5}=24\end{bmatrix}[/tex], solve this and we get that [tex]y=-3[/tex], Before we said [tex]x[/tex] equals [tex]-\frac{-3-y}{5}[/tex], So now we can plug in our value that [tex]y[/tex] equaled, and now we have [tex]\frac{-3-(-3)}{5}[/tex]. Two negatives equal a positive and we get that [tex]x=0[/tex].

Step-by-step explanation:

such a scale factor applies to all sides and lines.

we see that DE is 12 units, and AB is 4 units.

so,

12×f = 4

f = 4/12 = 1/3 is the scale factor

control : check the other side

FE = 6 units

6 × 1/3 = 2

so, the corresponding side in the small triangle must be 2 units long.

and indeed, CB is 2 units long. all correct.

130 sin 25 = x

x=54.940374

54.940374+2.75 = 57.7

Answer:

r = 7 cm

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( where r is the radius )

Given A = 154 , then

πr² = 154 , that is

[tex]\frac{22}{7}[/tex] r² = 154 ( multiply both sides by 7 to clear the fraction )

22r² = 1078 ( divide both sides by 22 )

r² = 49 ( take square root of both sides )

r = [tex]\sqrt{49}[/tex] = 7 cm

Answer:

k = -2

Step-by-step explanation:

Divide 22 by -11 as well as -11k by -11

(You have to divide both sides by the number that k is to find your answer)

22 divided by -11 = -2

-11k divided by -11 = k

meaning you would get the answer of k = -2

Answer:

angle x = 30 degrees

Step-by-step explanation:

180-117-33= x

180 - 117- 33= 30

117+33+x=180

117+33=150

180-150=30

x=30

117+33+30=180

180=180

Answer:

320

Step-by-step explanation:

I am assuming we are trying to find 16/5%.

5% is equal to 1/20, so we can make this into :

[tex]\frac{16}{\frac{1}{20} }=16*\frac{20}{1}[/tex]

This is equal to 16 x 20 = 320

Step-by-step explanation:

I guess the question is how many ounces are needed per paint. right ?

the colors are mixed in a ratio 3:5.

what that tells us is that there are 8 units of the whole paint (3+5), and yellow gets 3 out of these 8, and blue 5 out of these 8.

the total is 32 ounces.

so, each of the 8 units represents

32/8 = 4 ounces.

and now we know :

yellow has 3 units

3×4 = 12 ounces

blue has 5 units

5×4 = 20 ounces
