Answer:
1156πcm²
Step-by-step explanation:
Diameter = 68cm
Therefore radius = 68 ÷ 2 = 34cm
Area of a circle = πr²
= π × 34cm × 34cm
= π × 1156cm
= 1156πcm²
NOTE: In case you're given the value of pi, substitute it into the formula to get your answer
Answer:
1.39
Step-by-step explanation:
Given the quadratic equation :
2x^2+3x-8 = 0
We could apply the quadratic equation formula :
a = 2 ; b = 3, c = - 8
The formula is stated as :
-b±sqrt(b² - 4ac)/2a
To save computation tune, we could use a calculator :
The roots are : - 2.886 ; 1.386
The positive solution rounded to the nearest hundredth is : 1.39
Answer:
Probability that the respondent has a pet given that the respondent has had a pet is
or 0.46.
Step-by-step explanation:
We are given the following results below;
37% have a pet now and have had a pet.
63% do not have a pet now.
81% have had a pet.
19% do not have a pet now and have never had a pet.
Let event B = respondent has a pet now
Now, Probability that the respondent has had a pet = P(A) = 0.81
Probability that the respondent has a pet now and has had a pet =
= 0.37
So, Probability that the respondent has a pet given that the respondent has had a pet is given by = P(B/A)
<u>This conditional probability is solved as ;</u>
P(B/A) =
=
= 0.46.
Answer:
B. (1.5, 1.5).
Step-by-step explanation:
Point A has coordinates (-3, -3) and point B is (6, 6).
The mid point is ((-3+6)/2 , (-3+6)/2)
= (3/2 , 3/2)
= (1.5, 1.5) (answer).
Answer: 24c + 13
Step-by-step explanation:
f(x) = 6x + 1
(4c + 2)
f(4c + 2) = 6(4c + 2) + 1
f(4c + 2) = 24c + 13
