Answer:
24
Step-by-step explanation:
there are six sides of a dice, numbered one through six. 5 and 6 are greater than four, so there is a 2/6 chance that you will roll a number greater than 4, or 1/3. multiply 72 times 1/3 and that equals 24. 24 out of the 72 (24/72 = 1/3)times is how much you could expect to get a number greater than 4.
4k^2=5k
4k^2-5k=0
k(4k-5)=0
4k-5=0 => x2=5/4=1.25
k=1.25
Answer:
Expected number of guests is 100.4.
Step-by-step explanation:
It is given that there are 161 guest if there is a heavy snow fall.
Also, the probability for a heavy snow fall is 0.40.
Therefore, P(X = 161) =0.4.
It is also given that there are 60 guests if there is a light snow fall.
The probability for a light snow fall is 1 - 0.4 = 0.6.
Therefore, P(X = 60) = 0.6.
Expected number of guests = (161)P(X = 161) + (60)P(X = 60)
= 161(0.4) + 60(0.6)
= 64.4 + 36
= 100.4
Answer:
$10.12
Step-by-step explanation:
first, find the price of one ounce of halibut, by dividing $27 by 16 because there are 16 ounces in a pound, and you get 1.6875. then you multiply that by how many ounces you are buying, which is 6, so your answer is 10.125. round to the nearest cent.
<u>Answer</u>
D
<u>Explanation</u>
9⁽¹/²⁾² = (9⁽¹/²⁾)²
= 9¹/² × 9¹/² (Since the base are the same, we can add the power.)
= 9⁽¹/² ⁺¹/²⁾
= 9 ¹
= 9
The correct simplification is D.
