Hi! If you know angles this is the perfect question. Please help thank you!!! <3

ElenaW [278]

Answer:

x = 60

Step-by-step explanation:

Add up all the angles, they make 360 since it forms a full circle

(2x-10) + (2x+40) +90 = 360 Combine like terms

4x + 120 = 360 solve for x

4x = 240

x = 60

△ABC is a right triangle with right angle at ∠B .

GuDViN [60]

We can use the tangent function to find the value of angle C.

tan ∠C = 29/38
tan ∠C = 0.76315789473

Now we will do inverse of tangent on both sides.

∠C ≈ 37°

Hope this helps :)

You and a friend play a game where you each toss a balanced coin. If the upper faces on the coins are both tails, you win $1; if

oksian1 [2.3K]

Answer: The mean and variance of Y is $0.25 and $6.19 respectively.

Step-by-step explanation:

Given : You and a friend play a game where you each toss a balanced coin.

sample space for tossing two coins : {TT, HT, TH, HH}

Let Y denotes the winnings on a single play of the game.

You win $1; if the faces are both heads

then P(Y=1)=P(TT)= $\dfrac{1}{4}=0.25$

You win $6; if the faces are both heads

then P(Y=6)=P(HH)= $\dfrac{1}{4}=0.25$

You loose $3; if the faces do not match.

then P(Y=1)=P(TH, HT)= $\dfrac{2}{4}=0.50$

The expected value to win : E(Y)= $\sum_{i=1}^{i=3} y_ip(y_1)$

$=1\times0.25+6\times0.25+(-3)\times0.50=0.25$

Hence, the mean of Y : E(Y)= $0.25

$E(Y^2)=\sum_{i=1}^{i=3} y_i^2p(y_i)\\\\=1^2\times0.25+6^1\times0.25+(-3)^2\times0.5\\\\=0.25+1.5+4.5=6.25$

Variance = $E[Y^2]-E(Y)^2$

$=6.25-(0.25)^2=6.25-0.0625=6.1875\approx6.19$

Hence, variance of Y = $ 6.19

Summer is approaching, so workers at the Lawrenceville Community Center are filling the pool. The volume of water in the pool x

Vanyuwa [196]

9514 1404 393

Answer:

The pool is being filled

Step-by-step explanation:

The function definition tells you ...

f(5) = the volume of water in the pool 5 minutes after they start

f(10) = the volume of water in the pool 10 minutes after they start

So, the inequality ...

f(5) < f(10)

means the volume of water in the pool 10 minutes after they start is greater than it is 5 minutes after they start. In short, they are filling the pool.
