S_A_V [24]

Answer:
9<sqrt(97)<10

Step-by-step explanation:
Perfect squares:
1
4
9
16
25
36
49
64
81
100
121
144
169
....so on

97 is between 81 and 100
So square root of 97 is between sqrt(81)=9 and sqrt(100)=10.

9<sqrt(97)<10

MariettaO [177]

Answer:

a triangle, I'm guessing 20ft and 24 ft on the outsides,

would be:

Equation to get the area of a triangle: (A*B)/2

(20*24)/2=Area

20*24= 480

480/2= 240

area= 240

Alex17521 [72]

Answer:

The require expected value of x is $\frac{9}{2}$

Step-by-step explanation:

Consider the provided information.

Mike will play a game in which he will toss a penny, a nickel, and a dime at the same time.

The probability of head is $\frac{1}{2}$

He will be awarded 3 points for each coin that lands with heads faceup.

Let the random variable x represent the total number of points awarded on any toss of the coins.

Thus the expected value is:

$\text{Expected value}=\sum x_i p(x_i)$

$\text{Expected value}=3\times \frac{1}{2}+3\times \frac{1}{2}+3\times \frac{1}{2}$

$\text{Expected value}=\frac{9}{2}$

Hence, the require expected value of x is $\frac{9}{2}$
