Add 4x^2+6x+9 to 2x^2+3x-9

Answer:

2/3

Step-by-step explanation:

outcomes are (1,2,3,4,5,6)

No. Of outcomes =6

no. More than 2 are : (3,4,5,6)

Therefore the probability is 4/6 = 2/3

The probability of rolling a number more than 2 is 2/3

Probability is the measure of the chances of an event happening.

Probability of an event is calculated by dividing the number of favorable outcomes of the given event divided by the total number of given outcome

Let E be an event , Probability of the event  E,

P(E) = outcomes favorable to E/ total outcomes

In an experiment a single six sided die is rolled

Therefore the possible outcomes are {1,2,3,4,5,6}

Total number of possible outcomes = 6

Let E be the of rolling a number greater than 2

Possible outcomes in E are {3,4,5,6}

number of favorable outcomes of E , n(E) = 4

The probability of E , P(E) = n(E) / total number of outcomes = 4/6  = 2/3

Therefore the probability of rolling a number more than 2 is 2/3 = 0.667

Answer:

7

Step-by-step explanation:

20.00 - 3.87 = 16.13

2.28 x 7 = 15.96

Number of key chain he can buy is 7 keychain

Given that;

Amount spend in shopping mall = $3.87

Cost of each key chain = $2.28

Amount he has = $20

Find:

Number of key chain he can buy

Computation:

Assume;

Number of key chain he can buy = a

So,

2.28a + 3.87 = 20

2.28a = 16.13

a = 16.13 / 2.28

a = 7.074

Number of key chain he can buy = 7

Answer:

Step-by-step explanation:

Given the length of the bugs as shown;

Lady bug = 3/8

Ant = 1/4

Firefly = 7/8

Honey bee = 0.8

Deer tick = 0.2

Before we arrange the length in ascending order (shortest to longest), we will have to represent them in percentage.

Lady bug = 3/8×100

= 300/8

= 37.5%

Ant = 1/4×100

Ant = 25%

Firefly = 7/8 × 100

Firefly = 87.5%

Honey bee = 0.8×100

Honey bee = 80%

Deer tick = 0.2×100

Deer tick = 20%

On rearranging in ascending order:

20%, 25%, 37.5%, 80%, 87.5%

Based on the insect

Deer tick, Ant, ladybug, honey bee, Firefly

Based on their length:

0.2, 1/4, 3/8, 0.8, 7/8

Answer:

We want to find:

[tex]y'*dx = dy[/tex]

Where:

[tex]y = x^4*sin(9x)[/tex]

Remember that when we have a function like:

f(x) = g(x)*h(x)

The derivation gives:

f'(x) = g'(x)*h(x) + g(x)*h'(x)

In this case we can define:

f(x) = y

g(x) = x^4

h(x) = sin(9x)

These functions are easy to differentiate:

g'(x) = 4*x^3

h'(x) = 9*cos(9*x)

Then we have:

[tex]y' = \frac{dy}{dx} = 4x^3*sin(9x) + x^4*9cos(9x)[/tex]

Then we can write:

[tex]dy = (4x^3*sin(9x) + 9x^4*cos(9x))dx[/tex]

Answer:

This might seem like an obvious thing to do, but Murphy points out that the date printed on the packaging isn't always an expiration date. A carton of eggs may not always need to be thrown out as soon as the date passes. The date is usually just an indicator of the egg's freshness.

"The expiration dates are not expiration dates. Sometimes they are, but most of the time, the printed date is a best used-by date or sell-by date," Murphy tells INSIDER. "So, that does not always mean that the eggs have gone bad. Food can be bad before the date. Eggs and other dairy products are temperature sensitive. If you left your carton of eggs out on the counter for an extended period of time, the eggs would actually go bad before the date."

Per Murphy, "bad," however, means that you shouldn't eat the egg because it has the potential to make you sick. But, eggs can still be fresh even if they have passed their sell-by or used-by date.

"The fresher an egg is, like a lot of things, the better it tastes. In terms of freshness, a company can put a sell-by date or best used-by date on the carton. There is no regulation on that. The date is a good indicator of freshness," said Murphy. "The closer you get to the date, the less fresh the eggs are going to be. But, just because you've hit that date or gone beyond it doesn't mean that the eggs are necessarily bad."

Step-by-step explanation:

The easiest way to tell whether or not a carton of eggs has gone bad is to do the float test. To conduct the float test, take one egg and place it in a bowl of room temperature water, according to Murphy. If the egg sinks to the bottom and lies flat on its side, it is still fresh. If the egg stands up on its end like it's standing up, then the egg has gone bad.

"When an egg is first laid and it's truly really fresh, it's completely full there is very little air inside. But, egg shells are porous. So, as time goes by the inside starts to evaporate and is replaced by air," said Murphy. "The amount of air in the egg depends on what happens to the egg when it is dropped into water. Generally, if an egg actually floats that's the point when an egg has gone bad."

Step-by-step explanation:

The percentage  of women who would like to stay at home and take care of their family due to the fact that they have a child younger than 18 is  [tex]p_1  =  57\%[/tex]

The percentage of women who would rather work outside their home due to the fact that they don't have children is   [tex]p_2 =   58\%[/tex]

The  margin of error is [tex]E = 0.031[/tex]

Gnerally the point estimate of all US women with a child under 18 that would like to stay at home is mathematically represented as

       [tex]\^ p =  \frac{57}{100}[/tex]

       [tex]\^ p = 0.57[/tex]

Gnerally the interval estimate for the proportion of all US women with a child under 18 that would like to stay at home is mathematically as

       [tex]\^ p -E  < p <  \^ p +E[/tex]

=>    [tex]0.57 -0.031 <p<  0.57 + 0.031[/tex]

=>    [tex]0.539 <p< 0.601[/tex]

The volume of a cube is 17 cubic inches.

The formula used to find the volume of a cube is given by :

Answer:

Step-by-step explanation:

Tye length of the ramp can be gotten using Pythagoras theorem.

Horizontal distance = 10ft.

Vertical distance = 3ft

Length of the ramp² = 10²+3²

Length of the ramp² = 100+9

Length of the ramp² = 109

L² = 109

L =√109

L = 10.44ft

Hence the length of the ramp is 10.4ft to the nearest tenth

Answer:

150 adults, 270 kids.

Step-by-step explanation:

We can make a set of equations with the given information:

Adult=X

Kids=Y

3x+1y=720

x=y=420

420-X=Y

3x+420-x=720

2x+420=720 720-420=300

300/2=150

X=150, there were 150 adult visitors which means there are 270 children
