Suppose an opaque jar contains 3 red marbles and 10 green marbles. The following exercise refers to the experiment of picking tw

kow [346]

Answer:

$\frac{5}{13}$

Step-by-step explanation:

Given,

Red marbles = 3,

Green marbles = 10,

So, the total marbles = 3 + 10 = 13,

$\because \text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

Since, here replacement is not allowed,

Thus, the probability of getting a green marble and a red marble

= first red and second green + first green second red

$=\frac{3}{13}\times \frac{10}{12}+\frac{10}{13}\times \frac{3}{12}$

$=2\times \frac{3}{13}\times \frac{10}{12}$

$=\frac{30}{78}$

$=\frac{5}{13}$

Note : The probability of getting a green marble first and a red marble second

= $\frac{10}{13}\times \frac{3}{12}$

$=\frac{30}{156}$

$=\frac{5}{26}$

what is the measure of the base angle,x, of the isosceles triangle shown below? round your answer to the nearest tenth of a degr

MAVERICK [17]

Answer:

x ≈ 49.7°

Step-by-step explanation:

Since, the given triangle is an isosceles triangle,

Two sides having measure 17 units are equal.

Opposite angles of these equal sides will be equal.

Measure of the third angle = 180° - (x + x)°

By sine rule,

$\frac{\text{sinx}}{17}=\frac{\text{sin}(180-2x)}{22}$

$\frac{\text{sinx}}{17}=\frac{\text{sin}(2x)}{22}$ [Since, sin(180 - θ) = sinθ]

$\frac{\text{sinx}}{17}=\frac{2(\text{sin}x)(\text{cos}x)}{22}$

$\frac{\text{sinx}}{17}=\frac{(\text{sin}x)(\text{cos}x)}{11}$

$\frac{1}{17}=\frac{(\text{cos}x)}{11}$

cos(x) = $\frac{11}{17}$

x = 49.68°

x ≈ 49.7°
