Answer:
13 customers use to text,
10 customers use the Internet,
the probability that a randomly selected customer who is on plan B uses the phone most often to text is
Step-by-step explanation:
A phone company surveys a sample of current customers to determine if they use their phones most often to text or use the Internet.
Plan B:
13 customers use to text,
10 customers use the Internet,
23 customers in total.
The probability that a randomly selected customer who is on plan B uses the phone most often to text is
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
Answer:
5.6% to nearest tenth.
Step-by-step explanation:
Amount after 17 years
= 23300 = 9000(1 + r/365)^(17*365) where r = interest rate as a fraction.
(1 + r/365)^(17*365) = 23300/9000 = 2.588889
Taking logs of both sides:
17*365 log (1 + r/365) = log 2.588889
log(1 + r/365) = log 2.588889 / (365*17)
log(1 + r/365) = 0.0000665775
Removing the logs (by taking each side to the base 10) :
1 + r/365 = 1.000153312
r/365 = 0.000153312
r = 0.05596
As a percent this is 5.596%
Looooking for x so the answer is
X=7
For this, we use the Pythagorean Theorem to calculate for the side length of the triangle. This can only be used given your triangle is a right triangle. It is expressed as:
c² = a² + b²
where c is the hypotenuse.
c² = 3² + 3²
c = 3√2
Therefore, the perimeter is,
P = 3 + 3 + 3√2 = 6 + 3√2 ----------> Second option
