To calculate the HDD for the month of January in State College, PA, we need to first determine the base temperature. The base temperature is the temperature below which a building needs to be heated in order to maintain a comfortable indoor temperature. In this case, we will use a base temperature of 65 degrees F.

To calculate the HDD, we need to subtract the average daily temperature from the base temperature and sum up the values for each day of the month. If we assume that January has 31 days, we can calculate the HDD as follows:

HDD = (65 - 35) x 31
HDD = 930

So the HDD for the month of January in State College, PA is 930. This means that during the month of January, there were 930 heating degree days, which indicates the amount of heating required to maintain a comfortable indoor temperature. It is important to note that the HDD can vary depending on the base temperature used, so it is important to choose a base temperature that is appropriate for the climate and the building being heated.

The cost per pound of the cinnamon tea and of the spice tea would be = cinnamon $31.76 dollars per pound

spice $58.24 dollars per pound.

The volume of the cinnamon tea = 8 Ib

The volume of the spice tea = 6 Ib

The total volume of mixture = 14 Ib

The volume of the cinnamon tea = 4 Ib

The volume of the spice tea = 16 Ib

The total volume of mixture = 14 Ib

Add the both constitutes of the mixture;

Total volume of cinnamon tea in both mixture = 8+4 = 12 Ib.

Total volume of spice tea in both mixture = 6+16 = 22 Ib

Total weight of the both mixture = 12+22 = 34 Ib

Total price for both mixture = 38+52 = $90

The cost of cinnamon alone;

= 12/34 × 90/1

= 1080/34

= $31.76

The cost of spice tea = 90- 31.76 = $58.24.

Answer: 529.3 downloads

Explanation:

Standard version size = 2.1 MB

High quality version = 4.7 MB

The high-quality version was downloaded twice as often as the standard version

H = 2 S

The total size downloaded for the two versions = 3335 MB

H + S = 3335

We have the system:

H = 2 S (a)

H + S = 3335 (b)

Put A into B

(2S ) + S = 3335

3S = 3335

S= 3335/3

S= 1,111.67 MB

Divide the total MB of standard versions by the size of each standard version.

1,111.67 / 2.1 = 529.3 downloads

As a result, 35% of circus performers work with animals, whereas 70% of the circus's 200 performers work with animals.

Percentages are just fractions with a denominator of 100. We use the percent sign (%) beside a number to indicate that it is a percentage. For instance, if you answered 75 questions correctly out of 100 on a test (75/100), you would have received a 75%. A percentage is a figure or ratio that may be stated as a fraction of 100 in mathematics. If we need to compute the percentage of a number, divide it by the entire and multiply by 100. As a result, the percentage denotes a part per hundred. The term % refers to one hundred percent. The sign "%" represents it.

Here,

To find the percent of performers who work with an animal, we need to divide the number of performers who work with an animal by the total number of performers and multiply by 100.

Let's perform the calculation:

70 / 200 * 100 = 35%

Therefore, 35% of the performers in the circus work with an animal when 70 out of 200 performers in the circus work with an animal.

Answer: mean = 34

median = 33

mode = 33

Step-by-step explanation:

To figure out the mean you add every number and divide them by the number of values you added together so 27 + 31 + 33 + 33 + 35 + 45 = 204 then we would divide that by 6 = 34

To find the median you put all the numbers into order so which it already is meaning now you find the number in the middle which is 33 and 33 if there were two more values you would have to find the mean of them, but in this case its 33

The mode is the number which appears the most which is 33 as it appeared more than 2 times.

What is General intelligence?

General intelligence in mathematics refers to the ability to reason logically, solve problems, and understand abstract concepts in the field of mathematics. It is often referred to as mathematical intelligence or mathematical aptitude.

People with strong mathematical intelligence have the ability to think logically, identify patterns and relationships, and apply mathematical concepts to solve complex problems. They can quickly grasp mathematical concepts and principles, and are able to use mathematical reasoning to analyze data, make predictions, and draw conclusions.

However, it's important to note that mathematical intelligence is just one aspect of intelligence, and does not necessarily predict success in other areas of life. It is possible for someone to excel in mathematics while struggling in other areas, or vice versa.

Moreover, the concept of general intelligence itself has been a subject of debate among psychologists, with some arguing that it is a single, overarching ability, while others argue that intelligence is made up of multiple, more specific abilities.

Here we have total four patterns.

First pattern has 3 square, second has 6 squares , third has 11 squares and 18 squares.

Our first option is 3n.

Step-by-step explanation:

To find the slope (which is the rate of change), use (y1 - y2)/(x1 - x2).

x1 and y1 will be (0, 6)    

x2 and y2 will be (7, 0)

Note that x1 x2 y1 y2 can be any points on the line, I just chose these because they were x and y-intercepts.

(6 - 0)/(0 - 7)  =  6/7

Answer:

Below.

Step-by-step explanation:

I cant draw you a picture but it will be one right triangle inside the other where the vertical tower will be one leg common to 2 triangles and the base of the 2 triangles will be x and x+10 metres.

Tan 30 = h/ (x + 10)

tan 45 = h/x        where h is the height of the tower.

From the second equation  x = h / tan45

Substituting in the first equation;

tan30 = h / (h/tan45 + 10

Tan 30 = 1/ √3 and tan 45 = 1 so

1/ 1.732 = h/ (h + 10)

0.5774 = h/(h + 10)

h = 0.5774h + 57.74

0.4226 h = 57.74

h = 136.6 m to nearest tenth.

Average acceleration is defined as

\(a_{\rm ave} = \dfrac{\Delta v}{\Delta t}\)

Instantaneous acceleration is obtained by letting \(\Delta t\to0\).

\(a = \displaystyle \lim_{\Delta t \to 0} \frac{\Delta v}{\Delta t}\)

As velocity is a function \(v(t)\) of time \(t\), we have for some time interval \(\Delta t\),

\(\Delta v = v(t+\Delta t) - v(t)\)

so that

\(a = \displaystyle \lim_{\Delta t \to 0} \frac{v(t+\Delta t) - v(t)}{\Delta t}\)

and the right side is exactly the derivative of \(v(t)\).

Answer:

y = (-x-1)/2

Step-by-step explanation:

x1 = -3

y1 = 1

x2 = -1

y2 = 0

now

m = rise/run = (y2-y1)/(x2-x1) = (0-1)/(-1+3) = -1/2

so

y = mx + b

0 = -1/2(-1) + b

or, 0 = 1/2 + b

or, 0-1/2 = b

so, b = -1/2

so

y = mx + b

y = -x /2+ -1/2

or, y = (-x-1)/2

The approximate 95% confidence interval for the proportion of coworkers who have received this year's flu vaccine is (0.339, 0.501). Based on this information, it is true that 95% of the coworkers fall within the interval (0.339, 0.501), and we can be 95% confident that the proportion of coworkers who have received the vaccine is between 33.9% and 50.1%. However, it is false to say that there is a 95% chance that a randomly selected coworker has received the vaccine or that there is a 42% chance for a randomly selected coworker to have received the vaccine.

The approximate 95% confidence interval for the proportion of coworkers who have received this year's flu vaccine is (0.339, 0.501). Based on this information, we can determine which of the following statements are true:

a) 95% of the coworkers fall in the interval (0.339, 0.501).

This statement is true. The 95% confidence interval represents the range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. Therefore, we can say that 95% of the coworkers fall within the interval (0.339, 0.501).

b) We are 95% confident that the proportion of coworkers who have received this year's flu vaccine is between 33.9% and 50.1%.

This statement is true. The 95% confidence interval (0.339, 0.501) provides us with a range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. Therefore, we can say that we are 95% confident that the proportion of coworkers who have received the vaccine is between 33.9% and 50.1%.

c) There is a 95% chance that a randomly selected coworker has received the vaccine.

This statement is false. The 95% confidence interval does not represent a probability or chance for an individual coworker. It provides a range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. It does not give information about the likelihood of an individual coworker receiving the vaccine.

d) There is a 42% chance that a randomly selected coworker has received the vaccine.

This statement is false. The 42% represents the proportion of coworkers in the survey who have received the flu vaccine, but it does not represent the chance or probability for a randomly selected coworker to have received the vaccine. The 42% is a point estimate, not a probability.

e) We are 95% confident that between 33.9% and 50.1% of the samples will have a proportion near 42%.

This statement is false. The confidence interval (0.339, 0.501) does not directly provide information about the proportion of samples that will have a proportion near 42%. The confidence interval represents the range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies, but it does not specifically address the proportion of samples near 42%.

perimeter P = 2L + 2W

where

Perimeter P = 56 m

Width W = L - 8 m

find:

length L

width W

solution:

just plugin the values into the formula:

P = 2L + 2W

56 = 2L + 2(L - 8)

56 = 2L + 2L - 16

56 + 16 = 4L

L = 72/4

L = 18 m

solve for W:

substitute L=18 back into the equation W=L-8

W = 18 - 8

W = 10 m

therefore:

length L = 18 m

Width W = 10 m
