\huge \boxed{\mathfrak{Question} \downarrow}

  • ( 7 p ^ { 2 } + 3 p ) - ( 5 p ^ { 2 } + 4 ). Solve for standard form.

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

( 7 p ^ { 2 } + 3 p ) - ( 5 p ^ { 2 } + 4 )

To find the opposite of 5p²+4, find the opposite of each term inside the bracket.

7p^{2}+3p-5p^{2}-4

Combine 7p² and -5p² to get 2p².

\boxed{ \boxed{ \bf \: 2p^{2}+3p-4 }}

Help binomial distributions
Ymorist [56]

We have the formula to compute the probability of having exactly k successed over n trials, given a probability p of success (and implicitly a probability 1-p of failure), which is


P(\text{k successed on n trials}) = \binom{n}{k}p^k(1-p)^{n-k}


Now, the probability of at least 3 successes is the union of the following event: exactly three successes,exactly four successes and exactly five successes.


We can compute their probability and sum them:\binom{5}{3}\left(\frac{3}{7}\right)^3\left(\frac{4}{7}\right)^2 + \binom{5}{4}\left(\frac{3}{7}\right)^4\left(\frac{4}{7}\right)^1 + \binom{5}{5}\left(\frac{3}{7}\right)^5 \approx 0.36788


So, the answer is about 36.79%

prove that if two circles are tangent externally then the common internal tangent bisects a common external tangent.
Scilla [17]

Explanation:

Consider the attached diagram.

Circles A and B have mutual tangents CF and DE that intersect at point F.

We know that the two tangents to a circle from an external point are congruent, so ...

  FE≅ FC

  FD ≅ FC

By the transitive property of congruence, both segments congruent to FC are congruent to each other:

  FD ≅ FE

Therefore, CF is a bisector of DE.

Help ASAP Please). Show your work: It takes the earth 24 h to complete a full rotation. It takes Mercury approximately 58 days,
Westkost [7]

58 days * 24 hrs / day = 1392 hrs

30 mins / 60 mins = 0.5

1392 hrs + 15 hrs = 1407 hrs

1407 hrs + 30 mins = 1407.5 hrs
