A shopper buys cat food in bags of 33​ lbs. Her cat eats \frac{3}{4}
4
3

​ lb each week. How many weeks does one bag last?

Answers

Total of 44 weeks does one bag last.

What are Fractions?

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Here, a is called the numerator and b is called the denominator

Total amount of cat food = 33 lbs in one bag

Amount of food cat eats each week = 3/4 lb = 0.75 lb

Number of weeks one bag of cat food last = 33 / 0.75

                                                                       = 44

Hence one bag of cat food will last for 44 weeks.

What is the difference between the theoretical and experimental probabilities of getting heads?

A. 0.5
B. 0.0
C. 0.3
D. 0.1

Answers

Answer:

c 0.3

Step-by-step explanation:

there is are 50/50 chance when a coin is flipped but according to the data it is 80/20 so if to take 80-50=30 so it is a 0.3  change in probability.

The difference between the theoretical and experimental probabilities of getting heads is 0.3.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

A fair, unbiased coin was flipped 10 times.

The result is shown in the table.

Total number of outcomes = 10

For the experimental probability,

Number of heads = 2

Experimental Probability of getting heads, E = 2/10 = 0.2

For the theoretical probability,

Theoretical Probability of getting heads, T = 1/2 = 0.5

Difference = 0.5 - 0.2 = 0.3

Hence the difference is 0.3.

Answers

Answer:

Part E

When reflected across x axis, your y coordinate will be negative and the x coordinate will be the same. ex.

Mississipi has the lowest income at 40.6 thousand dollars.Mississippi also has about 207 bacherlors degree per 1000 people what does the linear model estimate for that number of bachelors degrees per 1000 per person for Mississippi based on the median income? How good is this estimate?

Answers

Answer: A linear model is a type of mathematical equation that describes the relationship between two variables, such as median income and the number of bachelor's degrees per 1000 people. In order to estimate the number of bachelor's degrees per 1000 people for Mississippi based on the median income, you would need a linear equation that describes that relationship.

Without that equation, it's not possible to estimate the number of bachelor's degrees per 1000 people for Mississippi based on the median income.

Additionally, without more information about the data that the model was trained on, the correlation between median income and the number of bachelor's degrees per 1000 people and how accurate and reliable the model is, it's difficult to determine the goodness of this estimate. However, in general, a linear model may provide only a rough estimate, especially if the relationship between the variables is complex or non-linear.

The total area is 360 square meter.

What is Area?

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.

Given:

We get Three Rectangle

First Rectangle:

length = 12 m

width = 16 m

So, Area = 12 x 16 = 192 square meter.

Second Rectangle:

length = 8 m

width = 12 m

So, Area = 8 x 12 = 96 square meter.

Third Rectangle:

length = 12 m

width = 6 m

So, Area = 12 x 6 = 72 square meter.

Thus, the total area = 192 + 96+ 72 = 360 square meter.

r = R/100

r = 2.6/100

r = 0.026 rate per year,

Then solve the equation for A

Answers

The rate of change of the surface area A(t) of the prism is 136 kilometers per minute.

What does rate of change mean?

An indicator of how one quantity changes in proportion to another is called a rate of change. If x and y are the independent and dependent variables, respectively, then the rate of change is equal to y-to-x conversions. Positive or negative change rates are possible.

Surafce area of a prism is equal to

2(Area of base) + (perimeter of base)(height)

It is given that db/dt= -7 and dh/dt -=10.

At a particular instant b= 4km, h=9 km.

Now we will substitute the values in this formula:

[tex]\frac{ds}{dt}=-4*4*7-4*4*7+ 4*9*10\\\frac{ds}{dt}=136[/tex]

A perfect square trinominal is the square of a binomial. Perfect square trinomials are in the form
a^2 + 2ab + b^2
or
a^2 - 2ab + b^2

Looking at the options, first check the leading term is a perfect square. They all are so we can’t eliminate anything. Next we check if the last term is a positive perfect square. The third option is not positive so we can eliminate that one.
Finally we check the center term. The first one does not have a middle term so we can eliminate that one.
The center term must be 2 times the square root of the first times the square root of the last.
The second option - square root of first term is 2m, square root of last term is 3n. 2*2m*3n is 12mn. That is not the middle term so the second option is not right.
The last option - square root of first term is 4x, square root of last term is 3y. 2*4x*3y is 24xy. That is the middle term. So the last option is the correct answer.

The length of an arc of a circle is one-eighth the circumference of the circle.Find the angle subtended by this arc at the centre if the radius of the circle is 14cm​

Answers

Given:

The radius of the circle is 14 cm.

The length of an arc of a circle is one-eighth the circumference of the circle.

To find:

The angle subtended by this arc at the center.

Solution:

Formula for arc length is:

[tex]s=2\pi r\times \dfrac{\theta }{360^\circ}[/tex]           ...(i)

Where, r is the radius and [tex]\theta [/tex] is the central angle.

The length of an arc of a circle is one-eighth the circumference of the circle.

[tex]s=\dfrac{1}{8}(2\pi r)[/tex]            ...(ii)

Where, [tex]2\pi r[/tex] is the circumference of the circle.

Using (i) and (ii), we get

[tex]2\pi r\times \dfrac{\theta }{360^\circ}=\dfrac{1}{8}(2\pi r)[/tex]

[tex]\dfrac{\theta }{360^\circ}=\dfrac{1}{8}[/tex]

[tex]\theta =\dfrac{360^\circ}{8}[/tex]

[tex]\theta =45^\circ[/tex]

Therefore, the central angle is 45 degrees.
