The probability it will rain in the next two weeks is 1/9 for this week and 1/5 for next week. What is the probability that it will rain this week and then rain next week?
Answers
Answer: 1/45
Step-by-step explanation:
The probability that it will rain this week and then rain next week will be the multiplication of the both the probability that it'll rain this week and probability that it'll rain next week.
Therefore, the answer will be:
= P(rain this week) × P(rain next week)
= 1/9 × 1/5
= 1/45
Therefore, the answer is 1/45.

I GIVE BRAIN LEST Which of the following is true about an
estuary?
It is all fresh water.
It is all salty water.
It has very few organisms.
It is affected by tides.
Answers
==========================================================
Explanation:
An estuary is where a river pours into the ocean. So that means fresh water mixes with salt water here. This allows us to rule out choices A and B.
According to NOAA, their site says "Estuaries are one of the most productive ecosystems in the world, so there is a great diversity of animals and plants that live there". In other words, a lot of plants and animals live here, so we can rule out choice C.
Choice D is the answer because tides do affect estuaries. This is simply because the ocean is pretty much right next to it, or attached to it. So it's expected that a high tide would cause the water level in an estuary to increase.
Answer:
it is affected by tides that's the conclusion I have come to

(a) Show your work.
(b) Is the product of 1/2x-1/4 and 5x^2-2x+6? equal to the product of 1/4x-1/2 and 5x^2-2x+6? ? Explain your answer
Answers
Answer:
1/2x - 1/4 * 5x^2 - 2x + 6 = 116/4 = 29
A. Work : 1/2x = 2/4x - 1/4 = 1/4x
5x^2 = 25 - 2x = 23x + 6 = 29x
1/4x * 29x = 1/4x * 116/4x = 116/4x = 29
B. 1/4x - 1/2 * 5x2 - 2x + 6 = -29
No, it is not equal to the product up above
Because its basically the same thing but the 1/2 and 1/4x
are switched which makes it negative

During a bean flipping experiment Fiona modeled her data using the function
f(t) = 4.127 (1.468) and Karl modeled his data with the function
k(t) = 0.897 (1.992) where t represents the number of trials and f(t) represents
the number of beans.
At what number of trials would Fiona and Karl have the same number of beans?
A.3
B4
C.5
0.6
Answers
Answer:
C.5
Step-by-step explanation:
Fiona:
After t trials, she would have:
[tex]f(t) = 4.127(1.468)^t[/tex]
Karl:
After t trials, he would have:
[tex]k(t) = 0.897(1.992)^t[/tex]
At what number of trials would Fiona and Karl have the same number of beans?
This is t for which:
[tex]f(t) = k(t)[/tex]
So
[tex]4.127(1.468)^t = 0.897(1.992)^t[/tex]
[tex]0.897(1.992)^t = 4.127(1.468)^t[/tex]
[tex]\frac{(1.992)^t}{(1.468)^t} = \frac{4.127}{0.897}[/tex]
[tex](\frac{1.992}{1.468})^t = 4.6[/tex]
[tex](1.35695)^t = 4.6[/tex]
[tex]\log{(1.35695)^t} = \log{4.6}[/tex]
[tex]t\log{1.35695} = \log{4.6}[/tex]
[tex]t = \frac{\log{4.6}}{\log{1.35695}}[/tex]
[tex]t = 5[/tex]
So the correct answer is 5 trials, option C.
