Answer: Second option is correct.

Step-by-step explanation:

Since we have given that

In Δ TSR,

TR= 3

SR= 4

∠STR = 66°

So, we will first congruent the two triangle i.e.

Consider ΔPTQ and ΔTSR,

PT= TR = 3 (∵ Radii of circle )

∠PTQ= ∠STR = 66° (∵ Vertically opposite angles are equal )

TS= QT = 3 ( ∵ Radii of circle )

∴ ΔPTQ ≅ ΔTSR ( By SAS congruence )

So, by CPCT( corresponding parts of congruent triangle ),

PQ= SR = 4

Hence, PQ =4

Therefore, Second option is correct.

Find the roots of the function f(x) = 3x4 - 48.

Andrew [12]

Answer:

$x=\pm 2\text{ or } x = \pm 2i$

Step-by-step explanation:

We are given:

$0=3x^4-48$

Factor:

$0=3(x^4-16)$

Difference of Two Squares:

$0=3(x^2-4)(x^2+4)$

Zero Product Property:

$(x^2-4)=0\text{ or } x^2+4=0$

Solve:

$x^2=4\text{ or } x^2=-4$

Take the square root. Since we are taking an even-root, it requires plus/minus:

$x=\pm 2\text{ or } x = \pm 2i$

Tasya [4]

Answer:

0.25 = 25% probability that it will rain today and ruin your picnic

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Cloudy skies

Event B: Rain

20% of all days start with clouds in the air

This means that $P(A) = 0.2$

50% of rainy days start with rain clouds in the air

50% of 10%. So

$P(A \cap B) = 0.5*0.1 = 0.05$

What is the probability that it will rain today and ruin your picnic

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.2} = 0.25$

0.25 = 25% probability that it will rain today and ruin your picnic
