Answer:
Probability = 0.356
Step-by-step explanation:
Probability of flooding = 25/100
= 0.25 lets call it p
So probability of not flooding = 1-0.25= 0.75. Lets call it q
So to find the probability of flooding in 1 out of 6 we use combination.
Probabilty = 6C1p^1q^5
Probabilty= 6 *0.25^1 *0.75^5
Probability = 0.356
The Daily News reported that 54% of people surveyed said that they would vote for Larry Salva for mayor. Based on the survey results, if 23,500 people vote in the election, how many people are expected to vote for Mr. Salva?
Answer:
12,690 people are expected to vote for Mr Salva
Step-by-step explanation:
Here, we want to know the number of people that is expected to vote for a particular candidate in an election given that 54% of people surveyed had said they would vote for the candidate.
Now to calculate the number of people expected to vote for Mr Salva, what we need to do is to find the number out of 23,000 that actually represents a percentage of 54%
To do this, we find 54% of 23,500
mathematically, we have;
54/100 * 23,500
= 12,690

The required number of boxes that the Taylor family eats in a week is 3 3/4 boxes.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is the fraction?Fraction is defined as the number of compositions that constitutes the Whole.
Here,
As of the given conditions,
1 person can eat 3/4 of box in one week
There are 5 persons in the family,
Total box of cereal that can be eaten = 5(3/4)
= 15/4

Area of a Circle

Answer:
Circle 1 = 24 pi in² = 452.2 in²
Circle 2 = 706.5 in²
Circle 3 = 271.6 in²
Step-by-step explanation:
In order to find the Diameter of a circle, you have to multiply the radius by 2. According to circle 1, 12in (radius) multiplied by 2 gets you 24 pi in².
In order to find the area, you multiply the radius² and then multiply it by pi or 3.14.
Is green the circumference or the diameter??? Had a little bit of confusion in that part, but I gave you the area only for Circle 2 and 3. For circle 1 I found the diameter (24 pi in²) and the area.

This diagram shows a block of stainless steel. The mass of the block is 930g.
Calculate the density of stainless steel.
Giving away brainliest! PLEASE HELP :)
Answer:
the answer is 7.75 g/cm3
Step-by-step explanation:
hope this helps
The density of the given block of stainless steel is 7.75 g/cubic cm. The value is obtained by the ratio of its mass to its volume.
What is the density of the cuboid?The cuboid has rectangular faces with length(l), width(w), and height(h). So, the density of the material which is required to make the cuboid is calculated as follows:
Density = mass/volume
Where the volume of the cuboid is the product of length, width, and height.
I.e., Density = mass/ (l × w × h)
Calculation:The given block has
length(l) = 8cm
width(w) = 5cm
height(h) = 3cm
The mass of the block is given as 930g
So, the density of the stainless steel is
Density = 930g/(8 × 5 × 3) cm³
= 930/120 (g/cm³)
= 7.75 g/cm³
Therefore, the density of the block is 7.75 g/cubic cm.

Plzzzzzzz help In the number 3.9928, how does the value of the 9 in the tenths place compare to the value of the 9 in the hundredths place? Drag and drop a fraction into the box to correctly complete the statement. The value of the 9 in the tenths place is the value of the 9 in the hundredths place.
Answer:
This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place
or
The value of 9 in the tenth place is 10 times the value of 9 in the hundredth place
Step-by-step explanation:
The decimal we are considering is 3.9928
The 9 in the tenth place has a value of 0.9
The value of 9 in the hundredth place has a value of 0.09
Now, what fraction of the 9 in the tenth place is the 9 in the hundredth place.
To mathematically get this, we just need to place the value of 9 in the hundredth place over the value of 9 in the tenth place;
Mathematically, that would be;
0.09/0.9 = 0.1 = 1/10
This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place
or
The value of 9 in the tenth place is 10 times the value of 9 in the hundredth place

Answer:

Step-by-step explanation:
3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)
Combine like terms
3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)
15(12x2+x+1) = 15(12x2+x+1)
Divide by 15
(12x2+x+1) = (12x2+x+1)
Since they are the same
x can be any real value
Answer:
All real values of x
Step-by-step explanation:
3(12x²+x+1)+12(12x²+x+1)=15(12x²+x+1)
(12x² + x + 1)(3+12) = 15(12x²+x+1)
15(12x²+x+1) = 15(12x²+x+1)
Since both sides are identical, all real values of x will satisfy the equation

Suppose S and T are mutually exclusive events, P(S) = 30%, and P(T) = 24%. Find P(S or T).
A) 6%
B) 54%
C) 720%
D) 7.2%
Answer: 54%
Step-by-step explanation:
In probability and logic theory, two events are said to be mutually exclusive or disjoint when both events cannot occur or happen at the same time.
A clear example of mutually exclusive event is the set of outcomes of a single toss of a coin which can either result in heads or tails, but can not be both.
P(S) = 30%, and P(T) = 24%
P(S or T) = P(S) or P(T) = 30% + 24%
= 54%

If P(A) = 0.25, P(B) = 0.60 and P(A and B) = 0.15, are the event A and B independent? Explain/show work.
Answer:
yes, event A and B independent
Step-by-step explanation:
given data
P(A) = 0.25
P(B) = 0.60
P(A and B) = 0.15
solution
we know here P(A and B) = 0.15
so we know here for independent
P(A and B) is = P(A) × P(B) .......................1
so we take here R.H.S here in equation 1 and put here value
P(A) × P(B)
P(A) × P(B) = 0.25 × 0.60
P(A) × P(B) = 0.15
so it is equal to L.H.S = R.H.S
so, we can say that A and B are independent

Which function best models the data?
y = 9,958(0.972)x
y = 0.972(9,958)x
y = 9,219x– 150
y = –150x + 9,219
Answer:
A
Step-by-step explanation:
y = 9,958(0.972)x
Function which best models the given data is -150x + 9219.
What is the solution of an equation?A solution is an assignment of values to the unknown variables that makes the equality in the equation true.
According to the given question
y represents the number of bees.
and, x represents the number of days.
Since, we have to find the function to represent the given data.
As, we know the given data are the solution of any function, so they must satisfy the function. For this we will take any value of x and y and check whether it satisfy the given function or not.
From the given data,
Let check for the point (0, 1000).
Substitute (0, 1000) in the given function one by one.
For, y = 9,958(0.972)x
At, x = 0
We get y = 0
⇒ ( 0, 1000) is not the solution of the function 9958(0.72)x
For, y = 0.972(9,958)x
At, x = 0
we get y = 0
⇒ (0, 1000) is not the solution for the function 0.972(9958)x
For, y = 9219x - 150
At x = 0
we get y = -150
⇒ (0, 10000) is not the solution of function, 9219x -150
For, y = -150x + 9219
At x = 0
y = 9219 which is nearly equals to 10000 because y is the estimated number of bees.
⇒ (0, 10000) is the solution of the given function y = -150x + 9219 .
Hence, the function which best models the given data is -150x + 9219.

According to the latest survey the mean world lifespan is 68.8 years the university of Oregon wants to see if the average life span of the residence of Oregon differs from the world average suppose a study followed a random sample of 26 Oregonians and found their average lifespan to be 72.8 years with a standard deviation of 2.5 years
Answer:
Step-by-step explanation:
We would set up the hypothesis test.
For the null hypothesis,
µ = 68.8
For the alternative hypothesis,
µ ≠ 68.8
This is a two tailed test.
Since the number of samples is small and no population standard deviation is given, the distribution is a student's t.
Since n = 26,
Degrees of freedom, df = n - 1 = 26 - 1 = 25
t = (x - µ)/(s/√n)
Where
x = sample mean = 72.8
µ = population mean = 68.8
s = samples standard deviation = 2.5
t = (72.8 - 68.8)/(2.5/√26) = 8.16
We would determine the p value using the t test calculator. It becomes
p < 0.00001
Assuming a significance level of 0.05, then
Since alpha, 0.05 > than the p value, then we would reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average life span of the residence of Oregon differs from the world average.
