Step-by-step explanation:

Step-by-step explanation:

Solution:

Given,

t1( first term ) a = -15

t2( second term ) b = -9

CD(Common Difference) = ?

We know,

CD = b - a

= -9 - ( - 15 )

= -9 + 15

= 6

Now,

t1 = -15

t2 = -9

t3 = -3

t4 = 3

t5 = a + ( n - 1 )CD

= -15 + ( 5 - 1 ) 6

= -15 + 24

= 9

t50 = a + (n - 1 ) CD

= -15 + ( 50 - 1 ) CD

= -15 + 49 × 6

= -15 + 284

= 269

So the sum of t50 is 269.

Step-by-step explanation:

cosecΘ = \(\frac{1}{sin0}\) = \(\frac{2}{\sqrt{3} }\) ( cross- multiply )

2sinΘ = \(\sqrt{3}\) ( divide both sides by 2 )

sinΘ = \(\frac{\sqrt{3} }{2}\) , then

Θ = \(sin^{-1}\) ( \(\frac{\sqrt{3} }{2}\) ) = 60°

Answer:

C.  60°

Step-by-step explanation:

by definition,  cosec(θ) is the reciprocal of sin(θ)

In other words ,

\(\text{cosec} \left( \theta \right) =\frac{1}{\sin \theta }\)

Then

\(\text{cosec} \left( \theta \right) =\frac{2}{\sqrt{3} }\)

\(\Longleftrightarrow \frac{1}{sin \left( \theta \right) } =\frac{2}{\sqrt{3} }\)

\(\Longleftrightarrow sin \left( \theta \right) =\frac{\sqrt{3} } {2}\)

Then

θ = 60°

The Recommended daily amount of fiber from the expression 8x is 32g.

what are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

Now,

Given Fiber in one serving of cereal=8gm which is 25% of one day need.

Let 8x be the fiber in cereal where x is multiple of 25%.

So, for one day need fiber needed is 100% i.e. x=4.

Therefore, Fiber needed =8*4=32g

Hence,

          The Recommended daily amount of fiber is 32g.

confidence interval: This tells us the degree of certainty or uncertainty that is existent in a sampling method.

To construct a 95% confidence interval for the population mean cholesterol level, we can use the following formula:

CI = x ± t*(s/√n)

where x is the sample mean, s is the sample standard deviation, n is the sample size, and t is the t-value from the t-distribution with n-1 degrees of freedom and a confidence level of 95%.

Substituting the given values, we have:

CI = 224 ± t*(12/√21)

Using a t-table with 20 degrees of freedom (since n-1=20), we find that the t-value for a 95% confidence interval is approximately 2.086.

Thus, the confidence interval is:

CI = 224 ± 2.086*(12/√21)

CI = (219.60, 228.40)

Therefore, the answer is option (c) (219.60, 228.40).

The standard deviation of the data set is approximately 2.7351. the mean of the data set is approximately 2.5833.

The mean and standard deviation for the given data set {0, 1, 1, 1, 2, 2, 2, 3, 3, 4, 5, 10} are as follows:

Mean: 2.5833 (rounded to four decimal places)

Standard Deviation: 2.7351 (rounded to four decimal places)

To calculate the mean, we sum up all the values in the data set and divide the sum by the number of values:

0 + 1 + 1 + 1 + 2 + 2 + 2 + 3 + 3 + 4 + 5 + 10 = 34

Mean = 34 / 12 = 2.8333

Therefore, the mean of the data set is approximately 2.5833.

To calculate the standard deviation, we follow these steps:

1. Find the mean of the data set, which is 2.5833.

2. Subtract the mean from each value in the data set and square the result:

  (0 - 2.5833)^2 = 6.6603

  (1 - 2.5833)^2 = 2.4385

  (1 - 2.5833)^2 = 2.4385

  (1 - 2.5833)^2 = 2.4385

  (2 - 2.5833)^2 = 0.3421

  (2 - 2.5833)^2 = 0.3421

  (2 - 2.5833)^2 = 0.3421

  (3 - 2.5833)^2 = 0.1711

  (3 - 2.5833)^2 = 0.1711

  (4 - 2.5833)^2 = 1.9959

  (5 - 2.5833)^2 = 5.9312

  (10 - 2.5833)^2 = 48.9602

3. Find the sum of all the squared differences:

  6.6603 + 2.4385 + 2.4385 + 2.4385 + 0.3421 + 0.3421 + 0.3421 + 0.1711 + 0.1711 + 1.9959 + 5.9312 + 48.9602 = 71.6206

4. Divide the sum by the number of values (12) and take the square root:

  √(71.6206 / 12) = 2.7351

Therefore, the standard deviation of the data set is approximately 2.7351.

In a hash table of size 6 with chaining, the keys 31, 32, and 19 will be placed in the table as follows:

Key 31: The hash value of 31 will be calculated using a hash function, which will generate a value between 0 and 5. Let's assume that the hash function generates a value of 1 for key 31. The value 31 will be placed in the linked list at index 1 of the hash table.

Key 32: The hash value of 32 will be calculated using the same hash function, which may generate a value different from 1. Let's assume that the hash function generates a value of 3 for key 32. The value 32 will be placed in the linked list at index 3 of the hash table.

Key 19: The hash value of 19 will be calculated using the same hash function, which may generate a value different from 1 and 3. Let's assume that the hash function generates a value of 0 for key 19. The value 19 will be placed in the linked list at index 0 of the hash table.

The evolution of the hash table for each key placement can be illustrated as follows:

Initially, the hash table is empty:
| | | | | | |

After placing key 31 in index 1:
| |31| | | | |

After placing key 32 in index 3:
| |31| |32| | |

After placing key 19 in index 0:
|19|31| |32| | |

As you can see, the values are placed in the linked lists at the respective indices of the hash table. This allows for efficient retrieval of values based on their keys, as the hash table can quickly locate the linked list where the value is stored.

Step-by-step explanation: math

The ascending order of increasing functions are,

y = (3/4)x - 10 < y = (1/2)x - 2 < y = (4/3)x - 7/3 < y = (3/2)x - 11/2

< y = (5/2)x + 10.

The equation of a line in slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

The y-intercept, or (0,b), is the point where the line crosses the y-axis at x = 0. The slope represents the rate of change of the y-axis relative to the x-axis.

When the equation of the form y = mx + b, the slopes of the function can be used to sort them in ascending order.

The equations in ascending order are,

y = (3/4)x - 10 < y = (1/2)x - 2 < y = (4/3)x - 7/3 < y = (3/2)x - 11/2

In a heap, the height is defined as the number of edges on the longest path from the root to a leaf node. The height of a heap with n elements is at most log₂(n+1).

To find the minimum and maximum numbers of elements in a heap of height h, we can use the formula:

The minimum number of elements in a heap of height h is 2^h (a complete binary tree of height h with the minimum number of nodes).

The maximum number of elements in a heap of height h is 2^(h+1) - 1 (a complete binary tree of height h with the maximum number of nodes).

Therefore, the minimum and maximum numbers of elements in a heap of height h are:

Minimum: 2^h

Maximum: 2^(h+1) - 1

Note that not all values of h are valid heap heights. A heap must be a complete binary tree, so its height can only take on values that satisfy the formula: \(h < = log₂(n+1),\)where n is the number of elements in the heap.

The critical value that is used to construct a confidence interval for a proportion depends upon C. the confidence level and the sample size.

The critical value used to construct the confidence interval for proportion depends on:

1) The sample size:

The probability changes as the sample size changes as the distribution of the test statistics is dependent on sample size, thus the critical value will depend on sample size.

2) The confidence level:

The critical value is always calculated by using the confidence level, so it is dependent on it.

The sample proportion is the observed value which is used to perform the test, but not to construct the critical value.
