Answer:

Letter B matches the probability.

Step-by-step explanation:

Lucy throws a fair six sided dice.

Probability of the dice landing on a number between 1 and 6 = \frac{\text{Favorable outcome}}{\text{Number of events}}

= \frac{1}{6}

On a number line fraction \frac{1}{6} can be represented by,

An small section (A to B) will represent the fraction = \frac{1}{6}

Therefore, letter B will match the probability of a dice landing on a number between 1 and 6.

erastova [34]

Answer:

(a) The probability that a randomly selected alumnus would say their experience surpassed expectations is 0.05.

(b) The probability that a randomly selected alumnus would say their experience met or surpassed expectations is 0.67.

Step-by-step explanation:

Let's denote the events as follows:

<em>A</em> = Fell short of expectations

<em>B</em> = Met expectations

<em>C</em> = Surpassed expectations

<em>N</em> = no response

<u>Given:</u>

P (N) = 0.04

P (A) = 0.26

P (B) = 0.65

(a)

Compute the probability that a randomly selected alumnus would say their experience surpassed expectations as follows:

P(C) = 1 - [P(A) + P(B) + P(N)]\\= 1 - [0.26 + 0.65 + 0.04]\\= 1 - 0.95\\= 0.05

Thus, the probability that a randomly selected alumnus would say their experience surpassed expectations is 0.05.

(b)

The response of all individuals are independent.

Compute the probability that a randomly selected alumnus would say their experience met or surpassed expectations as follows:

P(B\cup C) = P(B)+P(C)-P(B\cap C)\\=P(B)+P(C)-P(B)\times P(C)\\= 0.65 + 0.05 - (0.65\times0.05)\\=0.6675\\\approx0.67

Thus, the probability that a randomly selected alumnus would say their experience met or surpassed expectations is 0.67.

Solve the system of equations x+y=4 and 3x+7y=32 by combining the equations
Nesterboy [21]

Answer:

x = -1

y = 5

Step-by-step explanation:

x+y=4

3x+7y=32

<em><u>To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.</u></em>

x+y=4,3x+7y=32

<em><u>Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.</u></em>

x+y=4

<em><u>Subtract y from both sides of the equation</u></em>.

x=−y+4

<em><u>Substitute −y+4 for x in the other equation, 3x+7y=32.</u></em>

3(−y+4)+7y=32

<em><u>Multiply 3 times −y+4.</u></em>

−3y+12+7y=32

<em><u>Add −3y to 7y.</u></em>

4y+12=32

<em><u>Subtract 12 from both sides of the equation</u></em>.

4y=20

<em><u>Divide both sides by 4</u></em>.

y=5

<em><u>Substitute 5 for y in x=−y+4. Because the resulting equation contains only one variable, you can solve for x directly.</u></em>

x=−5+4

<em><u>Add 4 to −5.</u></em>

x=−1
