1 Solve 8x - 9 = 15 for x.
Anna [14]

Answer:

x= 3

Step-by-step explanation:

8x - 9 =15

+9 on both sides

8x = 15 + 9

Add 15 and 9 to get 24

8x = 14

Divide 8 by both sides

x = 3

Sonam sold two cars for nu. 55055 each. one has gained him 16% while the other made him loss 16%. how much does he loss or gain
statuscvo [17]

Answer: Total Loss or Gain = $0

<u>Step-by-step explanation:</u>

Gain:   $55,055 (1 + 0.16)

        = $55,055 (1.16)

        = $63,863.80

Profit = $8,808.80

Loss:   $55,055 (1 - 0.16)

        = $55,055 (0.84)

        = $46,246.20

Loss = -$8,808.80

Profit + Loss

= $8,808.80 - $8,808.80

= 0

Answer:

c=\frac{16}{39}

Step-by-step explanation:

The probability density function is :

f(x)=c(1-\frac{1}{16}x^{2})

With 0 < x < 3

To be a valid probability density function :

\int\limits^b_a {f(x)} \,dx=1

Where a < x < b

And also

f(x) ≥ 0 for a < x < b

Applying this to the probability density function of the exercise :

\int\limits^3_0 {c(1-\frac{1}{16}x^{2})} \, dx=1

c\int\limits^3_0 {(1-\frac{1}{16}x^{2})} \, dx=1

c(3-\frac{1}{16}\frac{3^{3}}{3})=1

c(\frac{39}{16})=1

c=\frac{16}{39}

We can verify by replacing ''c'' in the original probability density function and integrating :

\int\limits^3_0 {\frac{16}{39}(1-\frac{1}{16}x^{2})} \, dx=

=\frac{16}{39}.(3)-\frac{1}{39}.(\frac{3^{3}}{3})=\frac{16}{13}-\frac{3}{13}=\frac{13}{13}=1

Also, f(x) ≥ 0 for 0 < x < 3
