Answer:

False.

Step-by-step explanation:

It is not possible to create a regular tessellation with a regular heptagon. A regular tessellation refers to a pattern of repeating shapes that completely covers a flat surface without any gaps or overlaps. The only regular polygon shapes that can form regular tessellations are the equilateral triangle, square, and hexagon. Regular heptagons do not have the symmetry necessary to form a repeating pattern that covers a flat surface without gaps or overlaps.

The shape of this histogram is skewed to the right since the highest frequency is found in the first class, and the frequencies decrease as the numbers increase.

The class width, also known as the class interval, is the difference between the upper and lower boundaries of a class. In this frequency distribution, the class width is 9 since the lower boundary of the first class is 54.5 and the upper boundary of the last class is 90.5. We can calculate the frequency of each class by counting how many numbers fall within the class boundaries. For example, the first class has 72 observations since there are 72 numbers that fall between 54.5 and 63.5. To calculate the relative frequency of each class, we divide the frequency of each class by the total frequency. For example, the relative frequency of the first class is 0.312 since 72/231 = 0.312. Once the frequencies and relative frequencies have been calculated, a histogram can be made to represent the data. The shape of this histogram is skewed to the right since the highest frequency is found in the first class, and the frequencies decrease as the numbers increase.

To determine how many cakes Lionel makes in one hour, we can use the following formula:

cakes per hour = total cakes / total hours worked

On Monday, Lionel made 7 cakes in some number of hours, so we don't know how many cakes he made per hour that day. However, on Tuesday, he made an additional 6 cakes (13 total cakes - 7 cakes made on Monday), and he worked for 2 hours longer than he did on Monday. Therefore:

cakes per hour on Tuesday = 6 cakes / 2 hours = 3 cakes per hour

So Lionel made 3 cakes per hour on Tuesday. We don't have enough information to determine how many cakes he made per hour on Monday.

The linear function relationship between the change in the median home value and the year, indicates that we get;

a) The home values increased at a higher rate in Connecticut

b) The median home value in West Virginia in 2010 is $80,721

c) The home values in both states are equal in 1915

A linear function relationship can be expressed in the form; y = m·x + c. Where, m is the slope of the graph of the function and c is the y-intercept.

a) The rate of increase of the home value, where the values of the house change linearly can be found as follows;

Rate of change of home value for West Virginia =  [tex]\frac{72800-33200}{200-1950} = 792[/tex]

The home values in West Virginia increases by about $792 per year

Rate of change of home values for Connecticut = [tex]\frac{166900-71900}{2000-1950} =1900[/tex]

The home values in Connecticut increases by $1900 each year

Therefore;

b) The increase in the home value in West Virginia per year is $792, therefore, the home value in 2010 can be found as follows;

The number of years between 2010 and 2000 = 2010 - 2000 = 10

Home value in 2010 = Home value in 2000 + 792 × 10

Home value in 2010 = $72800 + $792 × 10 = $80720

c) The equation for the median home value for West Virginia can be presented as follows;

y - 33200 = 792×(x - 1950)

y = 792×(x - 1950) + 33200

The equation for the median home value for Connecticut can be presented as follows;

y - 71900 = 1900×(x - 1950)

y = 1900×(x - 1950) + 71900

When the home values in West Virginia is equal to the home value in Connecticut, we get;

792 × (x - 1950) + 33200 = 1900 × (x - 1950) + 71900

1900·x - 792·x = 1900 × 1950 - 792 × 1950 + 33200 - 71900 = 2121900

1108·x = 2121900

x = 2121900/1108 ≈ 1915.07

The year the median value will be the same in both states is about 1915

Answer:

64.34 feet.

Step-by-step explanation:

To solve this problem, we can use trigonometric ratios, specifically the tangent ratio.

Let's denote the height up the wall that the ladder reaches as "h". We can then set up the following equation:

tan(65°) = h/30

To solve for h, we can multiply both sides by 30:

30 tan(65°) = h

Using a calculator, we can find that tan(65°) is approximately 2.1445. Multiplying this by 30 gives us:

h ≈ 64.34 feet

Therefore, the ladder reaches approximately 64.34 feet up the wall. Rounded to the nearest hundredth of a foot, the answer is 64.34 feet.

Looking at the derivative, we see that it is defined for all values of t, so there are no vertical tangents.

The critical spots where the slope of the curve is zero or undefinable must be located in order to identify the points of horizontal tangency.

Our first step is to determine y's derivative with regard to x:

dy/dx = 3t^2 - 0

In the event that the derivative is set to zero, we obtain:

3t^2 = 0

t = 0

We gain one crucial insight from this at (22, 0).

The places where the derivative is undefinable must be located in order to determine the vertical tangent. There are no perpendicular tangents when looking at the derivative because it is defined for all values of t.

The big-o for the expected work performed by a call to fib(n) (where n < maxmemo) will be constant.

If the function is implemented with memoization, i.e., storing the results of previously calculated Fibonacci numbers to avoid redundant calculations, the expected work performed by a call to fib(n) would be O(1) for n < maxmemo, regardless of the number of previous calls made to fib.

This is because if the function has already calculated fib(n) earlier, it can simply look up the result in the memoized dictionary and return the stored value without performing any additional calculations. Otherwise, it would calculate fib(n) once and store the result in the memoized dictionary for future lookups.

Therefore, the expected work performed by a call to fib(n) is constant, O(1), as long as the previously calculated Fibonacci numbers are stored in memory using memoization. The number of previous calls made to fib has no impact on the expected work performed by a call to fib(n) as long as n is less than maxmemo.

Measure of angle G is 62.5°.

For a regular polygon of any number of sides, the sum of its exterior angle is 360° (full angle).

In triangle EFG,

Measure of angle E = 55°

Measure of angle F should be less than 180 = x/2°

By the triangle sum theorem, the Sum of measures of all interior angles of triangle = 180°

m(∠E) + m(∠F) + m(∠G) = 180°

55° + x/2° + x/2= 180°

The post-neonatal mortality rate for the year is 1.1×10⁻⁷.

The post-neonatal mortality rate in a year is applicable when the death day lies between 28 and 364. First, divide the number of post-neonatal deaths by the number of live births. Then multiply the obtained value by 1000 to get the post-neonatal mortality rate.

It is known that 1 billion units = 10⁹ units. So, 20 billion live births will be 20×10⁹ live births. Also, the number of post-neonatal deaths is 2200.

So, use the formula, post-neonatal mortality rate = (the number of post-neonatal deaths)/(the number of live births).

post-neonatal mortality rate = 2200/(20×10⁹)

Divide the 8-digit student ID by the leftmost 3 digits to find q and r using the Quotient Remainder Theorem. If your 8-digit student ID is 12345678, then d = 123, n = 45,678, q = 371, and r = 45.

Suppose your 8-digit understudy ID is 12345678. Then, at that point, we can take the furthest left three digits to get d = 123. Also, we can take the excess 5 digits to get n = 45,678.

To find q and r, we can utilize the condition n = dq + r and address for q and r.

To begin with, we really want to see as the biggest various of d that is not exactly or equivalent to n. We can do this by separating n by d and taking the floor of the outcome:

q = ⌊n/d⌋ = ⌊45,678/123⌋ = 371

Then, we can track down the rest of taking away the result of d and q from n:

r = n - dq = 45,678 - 123 × 371 = 45,678 - 45,633 = 45

Along these lines, in the event that your 8-digit understudy ID is 12345678, d = 123, n = 45,678, q = 371, and r = 45.

The Remainder Leftover portion Hypothesis expresses that for any whole number n and positive whole number d, there exist whole numbers q and r with the end goal that n=dq+r, where q is the remainder and r is the rest of.
