0=-16t^2 +10 \\\\16t^2=10\\\\t^2=\dfrac{10}{16}=\dfrac{5}{8}\\\\t=\sqrt{\dfrac{5}{8}} \vee t=-\sqrt{\dfrac{5}{8}}\\\\t=\dfrac{\sqrt5}{\sqrt8} \vee t=-\dfrac{\sqrt5}{\sqrt8}\\\\t=\dfrac{\sqrt5}{2\sqrt2} \vee t=-\dfrac{\sqrt5}{2\sqrt2}\\\\t=\dfrac{\sqrt{10}}{2\cdot2} \vee t=-\dfrac{\sqrt{10}}{2\cdot2}\\\\t=\dfrac{\sqrt{10}}{4} \vee t=-\dfrac{\sqrt{10}}{4}

Answer:

plus or minus √10 / 4

Step-by-step explanation:

0=-16t^2 +10 becomes easier to solve if we rewrite it as 16t^2 = 10.

Then t^2 = 10/16 = 5/8, and t = plus or minus √(5/8), or

                                             t = plus or minus (√5) / √8), or

                                             t = plus or minus (√5)√8         √5*2√2

                                                                         ------------- = -------------------

                                                                                 8                    8

or                                                                 plus or minus √10 / 4

PLEASE HELP ASAP!
puteri [66]

The answer is B

To figure this out, all you have to do is put 2/3 into a ratio with 6 so it looks like 2/3:6 now get rid of the fraction by multiplying both sides by 3/2 to make the left side 1 and the right side 4.

Laura's school is holding an outdoor activities celebration event for its 20th anniversary. Laura decides to participate in the
Pachacha [2.7K]

Probabilities are used to determine the chances of Laura winning an activity

  • The value of p is 1/12
  • The expected score of the game is -1/6
  • The probability that she has a total score of 5 after two rounds is 0

<h3>How to calculate the value of p</h3>

To calculate the value of p, we make use of the following probability formula

\sum P(x) = 1

So, we have:

\frac 3{12} + \frac 1{12} + \frac 4{12} + \frac 2{12} + p + \frac 1{12} = 1

Collect like terms

\frac 3{12} + \frac 1{12} + \frac 4{12} + \frac 2{12} + \frac 1{12}  + p= 1

Evaluate the sums, on the left-hand side

\frac{11}{12} + p = 1

Subtract 11/12 from both sides

p = \frac 1{12}

Hence, the value of p is 1/12

<h3>(b) How to calculate the expected score</h3>

This is calculated using the following expected value formula

E(x) = \sum x * P(x)

So, we have:

E(x) = -3 * \frac{3}{12} -1 * \frac 1{12} + 0 * \frac 4{12} + 1 * \frac 2{12} + 2 * \frac 1{12} + 4 * \frac 1{12}

Evaluate the products

E(x) =  -\frac{9}{12} - \frac 1{12}  + \frac 2{12} + \frac 2{12} + \frac 4{12}

E(x) =  -\frac 2{12}

Simplify

E(x) =  -\frac 1{6}

Hence, the expected score of the game is -1/6

<h3>(c) The probability that she has a total score of 5 after two rounds</h3>

From the table, we have:

P(5) = 0

For after two rounds, we make use of the following equation

P(5) * P(5) = 0 * 0

P(5) * P(5) = 0

Hence, the probability that she has a total score of 5 after two rounds is 0
