David requires $13.5 to buy 2 more pumpkins.

Firstly calculating the cost of one pumpkin and then calculating the desired answer.

Cost of one pumpkin = total cost ÷ number of pumpkins

Keep the values in formula to find the cost of one pumpkin

Cost of one pumpkin = 33.75 ÷ 5

Performing division on Right Hand Side of the equation

Cost of one pumpkin = $6.75

Now, the amount required to buy 2 more pumpkins = 2 × 6.75

Performing multiplication on Right Hand Side of the equation

The amount required = $13.5

Thus, the amount required by David is $13.5.

Given that there will be 14 fires in a year, there will be an expected number of fires. There are more than 1000 points available in this question. We must determine the probability that a woman owned.

In a year, a fire will harm one in 12 homes. That is, given if n is equal to 12 and that the value of x is equal to 1, the probability of x being equal to 1 is also equal to 1. Hence, due to fire damage. We discovered that the probability value p equals 0.014, and we are aware that, in general, binomial probability, or the probability that x equals x, is equal to c x, p to the power of x times q to the power of n minus x. Substituting all of these values into the formula, where q = 1 - p, gives us the value of 12 c 1, or 0.014. The total power of 1 for q is 1 minus p, or 1 minus 0.014. 11 points is the power of 12 as a whole less 1. The result of simplification is 0.143865, so Therefore, we have determined that the likelihood of one out of every twelve homes experiencing fire damage is 0.143865 percent.

The inequality to determine when the cost of viewing n videos using

plan A is less than the cost of viewing n videos using plan B.

8 + 3n < 5n

Plan A is less expensive when n is greater than 2.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Two monthly plans:

Plan A:

Cost per video = $3

Flat rate per month = $8

Plan B:

Cost per view = $5

Flat rate = zero

The inequality to determine when the cost of viewing n videos using

plan A is less than the cost of viewing n videos using plan B.

8 + 3n < 5n

Solving for n.

8 < 5n - 3n

8 < 2n

8/4 < n

n > 2

This means when n is greater than 2 we get,

The cost of viewing n videos using plan A is less than the cost of viewing n videos using plan B.

Thus,

The inequality to determine when the cost of viewing n videos using

plan A is less than the cost of viewing n videos using plan B.

8 + 3n < 5n

Answer:

-4

Step-by-step explanation:

gradient = (y_2 - y_1)/(x_2 - x_1)

gradient = (14 - 6)/(-10 - (-8)) = 8/(-2) = -4

Easier to have it in the form

y=mx+c

y =x/3 + 14/3

Unfortunately not whole numbers so it won't go perfect through the edges of the boxes

Then you just make some x and y values yourself

Good starting point is 0 for both

ie when x is 0 then y =14/3

when y = 0 then x = -14

Which is off the graph in this case.

But using that idea if you pick an x or y value yourself you should be able to calculate its corresponding value.

You technically only need 2 sets of coordinates as it is a straight line but if you calculate more you can guarantee your line is correct

The probability that the athlete is either a football player or a basketball player is 93%.

What is probability?

Football players= 51%

Basketball players= 43%

Both football and basketball= 1%

Probability = Football players + Basketball players

- Both football and basketball

Probability= 51% + 43% -  1%

Probability= 93%

Inconclusion The probability that the athlete is either a football player or a basketball player is 93%.

Answer: Jennine must walk 11.36 blocks.

Step-by-step explanation:

Since each step is 18" long and she takes 1550 steps per block, a block must equal to 1550*18", or 27,900".

27,900" is roughly 0.44 miles.

Therefore 5mi. /0.44mi.  = ~11.36 blocks

8 families do not have cat or dog. And the probability of a family having a dog is 0.42

Here Given that,

We have total 59 families.

26 only have cat.

14 only have a dog.

And 11 have both cat and a dog

Now, we will show this information on Venn diagram

for Venn diagram see the attachment.

Now, we can say that 26+14+11=51 families have pets at home.

So,  we will find out that how many families do not have cat or dog

So,  

we have 59 total families and from 59 families 51 have cat or a dog or both at home.

So,

Families do not have cat or dog = 59-51

Families do not have cat or dog = 8

therefore,

8 families do not have a cat or a dog.

Now, we will choose one family and find out the probability of that family having a dog.

So, we have 59 total families and out of 59 families 14+11= 25 families have a dog at home.

So,

The probability of a family having a dog =(families that have a dog)/(total families)

The probability of a family having a dog =25/59

The probability of a family having a dog =0.42

Income that is earned comes under total earnings after taxes are deducted which one has already paid. Some of the income which is earned can include union strike benefits, specific retirement pensions, and long-term disability benefits.

Statistics, originally "description of states, countries") is the field dealing with the collection, organization, analysis, interpretation and presentation of data. When applying statistics to  scientific, industrial, or social problems, it is common to start with a statistical population or  model under study. A population can be various groups of people or things such as: For example, "everyone living in that country" or "all atoms that make up a crystal". Statistics deals with all aspects of data, including the planning of data collection with a view to designing surveys and experiments.

The volume of sphere in the diagram by entering the given radius into the volume formula is 36π cubic units.

Given that the volume of sphere is (4/3)×π×r³ and the radius is 3 units.

We want to the find the volume of sphere.

As we are given that the radius is 3 units and the volume of the sphere is (4/3)πr³.

So, firstly, we will substitute the value r=3 in the above formula, we get

V=(4/3)×π×(3)³

Now, we will simplify the above expression, we get

V=4π×9

V=36π cubic units

Hence, the volume of the sphere by entering the given radius into the volume formula for a sphere is 36π cubic units.
