Answer:

There is sufficient evidence to conclude that the distribution of responses is different now than it was historically.

Step-by-step explanation:

Since the p-value is less than the alpha significance level you reject the null hypothesis that the histrocial data matches the current.

We don't have enough evidence to conclude that the distribution of responses is different now than it was historically.

Human resources are the people who make up an organization's, business sector's, industry's, or economy's workforce.

A more specific concept is human capital, which refers to the knowledge and skills that individuals possess.

The chi-square goodness-of-fit test has a p-value of 0.089 at a significance level of 0.10. We cannot reject the null hypothesis because the p-value is greater than 0.10.

As a result, we lack sufficient evidence to conclude that the distribution of responses is different now than it was previously.

"We don't have enough evidence to conclude that the distribution of responses is different now than it was historically," is the correct answer.

Thus, this can be concluded regarding the given scenario.

Answer:

12 inches

Step-by-step explanation:

This is a square of sidee length 3 inches.  As there are four (equal) sides, the perimeter of this square magnet is 4(3 inches), or 12 inches.

Answer:

Range of x:  [tex]0\leq x < 12[/tex]    or    [tex]0\leq x\leq 11[/tex]

Largest possible value of [tex]x[/tex] is 19

Mean mark = 11.41 (nearest hundredth)

Step-by-step explanation:

The mode is the number that appears the most, so if the mode is 10, [tex]x[/tex] has to be smaller than 10.

We can say this in two ways:

[tex]0\leq x < 12[/tex]    or    [tex]0\leq x\leq 11[/tex]
since the number of points and players are positive integers.

The median is the middle value when the values in the data set are placed in order from smallest to largest.

If 10 is the median mark, to find the maximum number of 15s, sum the number of players scoring 5 and 10 points and subtract 1:

8 + 11 = 19

Therefore, the largest possible value of [tex]x[/tex] is 19.

The mean is the total of the numbers divided by how many numbers there are.  

To find the total marks, multiply the number of points by the number of players, and sum (using x = 19):

[tex]\textsf{Total points}=5 \times 8+10\times12+15 \times 19=445[/tex]

Total number of players = 8 + 12 + 19 = 39

[tex]\textsf{mean mark}=\dfrac{445}{39}=11.41\:\textsf{(nearest hundredth)}[/tex]

Answer:

0.8L = red

0.64L = yellow

0.06L = white

Step-by-step explanation:

R : Y : W

20 : 16 : 1.5

20 + 16 + 1.5 = 37.5

1.5 ÷ 37.5 = 0.04

0.04 × 20 = 0.8L = red

0.04 × 16 = 0.64L = yellow

0.04 × 1.5 = 0.06L = white

Answer:

Step-by-step explanation:

To solve for y, isolate it on one side of the equation.

First, switch sides.

c=y+a

y+a=c

Then, you subtract by a from both sides.

y+a-a=c-a

Solve.

Answer:

14.3

Step-by-step explanation:

Formula: a^2 + b^2 = c^2

9+196= 205 then find the square root of 205, approximate then use tenths.

Answer:

14.3

Step-by-step explanation:

Use the following equation:

a² + b² = c² , in which the variable c = hypotenuse, and a & b are the other legs.

It is given that the legs measure 3 and 14 respectively. Plug in the given numbers to the given leg variables:

a² + b² = c²

3² + 14² = c²

Simplify. First, solve the powers, and then combine like terms:

(3 * 3) + (14 * 14) = c²

9 + 196 = c²

c² = 205

Next, root both sides of the equation:

√c² = √205

c = √205 = 14.3178

c = 14.3 (Rounded to the nearest tenth).

14.3 is your answer.

The recursive definition of the geometric sequence is given by:

A. [tex]a_n = (0.8)a_{n-1}[/tex]

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The basic recursive relation is given as follows:

[tex]a_n = qa_{n-1}[/tex]

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

In this problem, considering the given sequence, the common ratio is given by:

[tex]q = \frac{6144}{7680} = \frac{7680}{9600} = \frac{9600}{12000} = 0.8[/tex]

Hence option A is correct.

The values are given as:

$12,000 $9,600, $7,680, $6,144

Calculate the common ratio using:

r = a2/a1

So, we have:

r = 9600/12000

Divide

r = 0.8

Recall that:

r = a2/a1

So, we have:

a2/a1 = 0.8

Multiply both sides by a1

a2 = 0.8a1

Rewrite as:

[tex]a_{2} = 0.8a_{2-1[/tex]

Substitute n for 2

[tex]a_{n} = 0.8a_{n-1[/tex]

Hence, the recursive definition of the sequence is (a) [tex]a_{n} = 0.8a_{n-1[/tex]

Answer:

Step-by-step explanation:

If an angle measures x degrees, the measure of its supplement is (180-x) degrees.

This means that x-62.4 = 180-x, meaning that x=121.2.

So, the angles are 121.2 and 58.8 degrees.

Answer:

5.291 x 10⁶

Step-by-step explanation:

Why is 5,291,000 written as 5.291 x 106 in scientific notation?

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 5,291,000 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 5,291,000

New Number: 5.291000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 5 . 2 9 1 0 0 0

Decimal Count: 1 2 3 4 5 6

There are 6 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 5.291 (Please notice any zeroes on the end have been removed)

b = 6

Now the whole thing:

5.291 x 10⁶

Step 4

Check your work:

10⁶ = 1,000,000 x 5.291 = 5,291,000

Answer:

  f(-1) = 3

  f(5) = 20

Step-by-step explanation:

When evaluating a piecewise-defined function, the first step is to locate the argument value in the correct domain. Then the corresponding function is evaluated in the usual way.

__

For x=-1, the relevant piece is the one defined for x < 4:

  f(x) = x² +2

  f(-1) = (-1)² +2 = 3

__

For x=5, the relevant piece is the one defined for x > 4:

  f(x) = 2x +10

  f(5) = 2(5) +10 = 20

The required Henry needs to score 18 points in his next game to have an average of 24 points per game.

The mean of the values is the ratio of the total sum of values to the number of values.

Here,
average = sum of all scores/number of scores

We know that Henry has played four games so far, and his scores are 30, 29, 22, and 21 points. Therefore, the sum of his scores is:

sum of scores = 30 + 29 + 22 + 21 = 102

Let's assume that Henry scores x points in his next game. Then, his total score for all five games will be,

total score = 102 + x

If his average is 24 points per game, we can set up the equation:

24 = (102 + x) / 5

120 = 102 + x

x = 18

Therefore, Henry needs to score 18 points in his next game to have an average of 24 points per game.
