Show the work for answer, if the area of a pizza is 153.94 square inches, find the length of its diameter
TEA [102]

Answer:

14 inch

Step-by-step explanation:

A = πr^2

153.94 = π * r^2

153.94/π = 49.001 = r^2

√49.001 = r = 7

radius * 2 = diameter

7 * 2 = 14 inch diameter

(35 Points)<br> Evaluate ƒ(x) when x = 6.
pychu [463]

The value of the function is 6

Step-by-step explanation:

The function that we have in this problem is

f(x)=\left \{ {{3x^2+1}, -4

This means that:

when x is between -4 (excluded) and 6 (excluded), the value of the function is 3x^1+2

when x is between 6 (included) and 9 (excluded), the value of the function is 6

In this problem, we are asked to evaluate f(x) when x = 6. Therefore, we are in the second case: therefore, the value of the function is 6,

f(x)=6

You randomly pick two numbers from 1 to 9 (including 1 and 9). A number that is chosen once could be chosen again. If at least o
Mnenie [13.5K]
Assume that you only include whole numbers (1,2,3,4,5,6,7,8,9) and not 3.5 and such
so if 1 is odd and less than 5 then it is
1 or 3, since 5 isn't included
then the other number, to be less than 5 when added,
must be
1+x<5
3+x<5
solve each
1+x<5
subtract 1
x<4
set of answers are 1,2,3

3+x<5
subtract 3
x<2
set of answer is 1
so the possible numbers are
1,2,3
that is 3 numbesr out of 9 so
probability=(total desired outcomes)/(total possible outcomes) so
disred outcomes=3
total possible=9
3/9=1/3
the probabiltiy is 1/3
