In fact, weather on consecutive days depends on similar atmospheric conditions and therefore consecutive days are not independent events.With the weather forecast of the previous exercise, the probability that it rains over the weekend (either Saturday or Sunday) isA. 0.7516B. 0.3758 C. 0.2484D. Because consecutive days are not independent, we cannot compute P(rain both days) with the information given.
Question is incomplete :
The weather forecast for the weekend is a 46% chance of rain for Saturday and a 54% chance of rain for Sunday. If we assume that consecutive days are independent events, What is the probability that it rains over the weekend (either Saturday or Sunday)? Please use 3 decimal places.

Answer:
0.7516 ;
D.) Because consecutive days are not independent, we cannot compute P(rain both days) with the information given.
Step-by-step explanation:
Let :
Saturday = A ; Sunday = B
P(A) = 0.46 ; P(B) = 0.54
If A and B are independent :
P(AuB) = P(A) + P(B) - P(AnB)
P(AnB) = P(A) * P(B) = 0.46 * 0.54 = 0.2484
P(AuB) = 0.46 + 0.54 - 0.2484
P(AuB) = 0.7516
If A and B are not independent, and how the weather on Saturday affect the weather on Sunday and vice versa. Hence, we cannot compute AuB

That means ...
x = 2.5 × 4 = 10
y = 2.5 × 3 = 7.5
hi what is 24/30 simplified to
Answer:
12/15 or .8
Step-by-step explanation:
So first you divide both the numerator and denominator by 2 because it’s the biggest number that goes into both 24 and 30
24 and 30 simplified by 2 gives us 12 and 15
you can’t simplify any further so your answer is 12/15
If you want a decimal, then you divide 24 by 30 and your answer is .8

It’s for question 4
Answer:
$6,000
Step-by-step explanation:
We have to start by finding the conversation rate.
So, we can divide 9,600 by 8 to find how much the ratio is being multiplied by.
9,600 / 8 = 1200
Now that we know the conversion rate, we can multiply by five to find how much the expenses really cost, according to the ratio.
1200 * 5 = 6000
Their expenses this month are 6000

The area of a rectangle 320in^2. The ratio of the length to the width is 5:4. Find the length and the width
Answer:
30 in length 24inches width
Step-by-step explanation:
Multiply the multiples if 5 and 4 together until you reach 720.
5*4=20
10*8=80
15*12=180
20*16=320
25*20=500
30*24=720
Your length is 30 in and your width is 24in.
gordon rolls a fair dice 660 times. how many times would gordon expect to roll a two?
Answer:
110
Step-by-step explanation:
a probabability of rolling a 2 on a dice is 1/6, and times that by 660 is 660/6 which equals 110
hope this helps!
please give brainliest. Thanks!
Answer:
110 times
Step-by-step explanation:
The probability (P) of rolling a 2 is
P(2) = [tex]\frac{1}{6}[/tex]
expected number = [tex]\frac{1}{6}[/tex] × 660 = 110

When a number is decreased by 8.3%, the result is 50. What is the original number to the nearest tenth?
I'm pretty sure the answer would be 2.
Sorry if it's wrong
If a quantity is decreased by x% the new value of that quantity is (100 -x)% of the old one.The value of original number nearest to tenth is 55.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The percentage of decrease = 8.3%
The number obtained after decrease = 50
Since the number obtained after decrease is the original number minus the decrement in the number by 8.3%.
Thus, the expression for original number N is given by,
N - 8.3% of N = 50
=> N - (8.3 / 100) × N = 50
=> (91.7 / 100) × N = 50
=> N = 50 × (100 / 91.7)
=> N = 54.52
Nearest to tenth its value is 55.
Hence, the original number nearest to tenth is 55.
