Nesterboy [21]3 years ago

Answer:

The mean would be 82

Step-by-step explanation:

To find the mean you add up all the numbers.

68 + 73 + 95 + 81 + 85 + 90 + 77 + 84 + 75 + 92 = 820

Then you divide that be the amount of numbers are given to you.

820 \div 10 = 82

And that is how you find the mean.

Sorry if it is wrong I'm tired.

Guests arrive in groups of three to a party. 5 people leave the party early. If y is the number of people left at the party, and
Scrat [10]

Answer:

1, 3, 4, and 10

Step-by-step explanation:

To get a y value, substitute the x value into the equation they gave you (y = 3x - 5). For the x value 2:

y = 3(2) - 5

y = 6 - 5

y = 1.

To get a missing x value, solve for x in the equation they gave you. You were given the y value, so you can substitute that into the equation.

(4) = 3x - 5

Add 5 to both sides

9 = 3x

Divide both sides by 3

3 = x

Do the same with 7

(7) = 3x - 5

Add 5

12 = 3x

Divide by 3

4 = x

For the last one, you're given x so substitute it into the equation:

y = 3(5) - 5

y = 15 - 5

y = 10

let f(x) = 2x^2+5-e^x , use the intermediate value theorem to show that the f(x) has a root in the interval [3,4]?
sergiy2304 [10]

9514 1404 393

Answer:

  sign(f(3)) ≠ sign(f(4))

Step-by-step explanation:

The intermediate value theorem tells you that a sign change between f(a) and f(b) means there is a root in the interval [a, b].

Here, we have f(3) ≈ +2.9 and f(4) ≈ -17.6, so there is a root in [3, 4].

_____

The root is approximately 3.27560108885.

Of the eighth graders at the Paxton​ School, 99 played​basketball, 9 played​ volleyball, 10 played​ soccer, 1 played basketball
otez555 [7]
<h2>Answer:</h2>

<em><u>(a). 110</u></em>

<em><u>(b). 95 </u></em>

<em><u>(c). 2</u></em>

<h2>Step-by-step explanation:</h2>

In the question,

Number of students who played Basketball = 99

Number of students who played Volleyball = 9

Number of students who played Soccer = 10

Number of students who played Basketball and Soccer only = 1

Number of students who played Volleyball and Soccer only = 2

Number of students who played Basketball and Volleyball only = 1

Number of students who played Basketball, Volleyball and Soccer only = 2

So,

We can see from the <u>Venn diagram</u> shown below,

Number of students who played only Basketball = 99 - (1 + 2 + 1) = 95

Number of students who played only Volleyball = 9 - (1 + 2 + 2) = 4

Number of students who played only Soccer = 10 - (1 + 2 + 2) = 5

(a).

Number of students who played atleast one of three sports = Sum of all the sections in the Venn Diagram

= (95 + 1 + 2 + 1) + (4 + 2) + 5 = 110

(b).

Students who played Basketball only = 95

(c).

Number of students who play Volleyball and Soccer but not Basketball = 2
