Answer:

The probability you see a dolphin or a whale on both days is 0.64

Step-by-step explanation:

Consider the provided information.

It is given that the brochure claims an 80% chance of siting a dolphin or a whale.

The provided claims can be written as: 80% or 0.80

Let say first day you see a dolphin or a whale and same happen on the next day.

Thus, the probability is:

0.80 × 0.80 = 0.64

Probability of see them on both days is 0.64

Hence, the probability you see a dolphin or a whale on both days is 0.64

The area of triangle PQR is 273 cm. Given that PQ = 12.8cm and PQR = 107°, find QR.​
storchak [24]

\text{Area of triangle} = \dfrac 12 \times PQ \times QR \times  \sin \angle PQR \\\\\\\implies  273= \dfrac 12 \times 12.8 \times QR \times \sin 107^{\circ}\\\\\implies 273 = 6.4 \sin 107^{\circ}  \times QR\\\\\\\implies QR = \dfrac{273}{6.4 \sin 107^{\circ}} = 44. 606~~ \text{cm}

The linear combination method is applied to a system of equations as shown.
tensa zangetsu [6.8K]

Answer:

(9,3)

Step-by-step explanation:

4(.25x + .5y = 3.75) → x + 2y = 15

(4x – 8y = 12) → x – 2y = 3

2x = 18

Divide both sides by 2

x = 9

Substitute x = 9 into  x + 2y = 15

9 + 2y = 15

Subtract 9 from both sides

2y = 6

Divide both sides by 2

y = 3

Solution

(9, 3)
