What is the distance between J and K

Answer:

180°

because x is the mid pf 0° and 360°

Answer:

7x=28

x = 4

x/9=3

x = 27

5x=125

x = 25

14=x÷2

x = 28

8x=40

x = 5

Answer:

x= -16

Step-by-step explanation:

g(x) =-2x-4

g(6)=-2(6)-4

g(6) = -12-4

g(6)=-16

The value of g(6) for the given function g(x) = -2x – 4 will be -16.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

Given the function,

g(x) = -2x – 4

Now,

g(6) means value of g(x) at x = 6

So,

g(6) = -2(6) - 4

g(6) = -12 - 4 = -16

Hence "The value of g(6) for the given function g(x) = -2x – 4 will be -16".

Answer:

(a) Mean = 55.9

(b) Median = 59

(c) Mode = No mode

(d) Midrange = 93

Step-by-step explanation:

(a) Mean

The formula for finding mean of an ungrouped data = Σx/n

Where

Σ is the sum of all the data

n is the number of data in the set

Therefore,

Σx=615

n = 11

Mean = 615/11

=55.9

(b) Median

Median is the middle number after arranging the set of data in either ascending or descending order.

By arranging the numbers, the middle is 59 which is the Median

(c) mode

Mode is the number that occurs most in a set of data.

From the given set of numbers, all the numbers appear once. Therefore, there is no mode

(d) Midrange

This is the difference between the biggest and the smallest number in a set of data.

Therefore,

the midrange = 97-4

=93

Answer:

x - 5 < -2

Answer is there

Answer:

B. The​ t-distribution has less spread as the degrees of freedom increase​ because, as n​ increases, s becomes closer to sigma by the law of large numbers.

Step-by-step explanation:

The sample standard deviation, s gets considerably closer to the population standard deviation, σ, this trend follows the proposition of the law of large numbers whereby the mean or average value changes as the sample size, n increases. According to the law of large numbers, as the sample size increases, the sample mean gets continously closer to the population mean, sample standard deviation follows this same trend and thus variability or spread decreases as sample size increases.

The plausible reason that explains why the t-distribution will have a less spread as the number of degrees of freedom increases is because: as n​ increases, s becomes closer to by the law of large numbers. (Option B)

Note the following:

Step-by-step explanation:

because of math boom

Answer:

part 1 : y = x^2 + 3x + 5

y = x + 13

solution:

x^2 + 3x + 5 = x + 13

x^2 + 2x -8 = 0

(x+4)(x-2) = 0

x = -4 or x = 2

if x = -4, y = 9

if x = 2 , y = 15

part 2 : x^2 + 2x + 1 = 0

(x + 1)^2 = 0

x = -1

y = 1

Answer:

Step-by-step explanation:

1. In general, restrictions on rational functions refer to values of the variable that make the denominator zero. The function will be undefined in that case. On a graph, such a location will show up as a "hole" or a vertical asymptote.

__

2. If ±2 are excluded from the domain, we expect factors of (x-2)(x+2) in the denominator. That is, the denominator will have a factor of (x²-4). (There may be other factors that do not have real zeros.)

__

3. A rational expression is a fraction the same as any other. The usual rules of addition, subtraction, multiplication, and division apply. For addition and subtraction, it can be useful to identify a common denominator. For multiplication and division, that is not so essential.

Perpendicular drawn from the center to the chord of a circle, bisects the chord.

AB = BC = 6

In right triangle ΔCBD,

By applying Pythagoras theorem,

CD² = BC² + BD²

The exact value of the function for the given x-value is of -5.

Step-by-step explanation:

In this question, we compute the numeric value of the function f(x) for x = -1, that is, we replace every instance of x in the function by -1.

f(x) = 5x for x = -1

[tex]f(-1) = 5(-1) = -5[/tex]

a. Above 337.8 grams.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 325 grams and a standard deviation of 10 grams.

This means that [tex]\mu = 325, \sigma = 10[/tex]

a. Highest 10 percent

This is X when Z has a pvalue of 1 - 0.1 = 0.9, so X when Z = 1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = 10*1.28[/tex]

[tex]X = 337.8[/tex]

So 337.8 grams.

b. Middle 50 percent

Between the 50 - (50/2) = 25th percentile and the 50 + (50/2) = 75th percentile.

25th percentile:

X when Z has a pvalue of 0.25, so X when Z = -0.675.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.675 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = -0.675*10[/tex]

[tex]X = 318.25[/tex]

75th percentile:

X when Z has a pvalue of 0.75, so X when Z = 0.675.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = 0.675*10[/tex]

[tex]X = 331.75[/tex]

Between 318.25 grams and 331.75 grams.

c. Highest 80 percent

Above the 100 - 80 = 20th percentile, which is X when Z has a pvalue of 0.2. So X when Z = -0.841.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.841 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = -0.841*10[/tex]

[tex]X = 316.59[/tex]

Above 316.59 grams.

d. Lowest 10 percent

Below the 10th percentile, which is X when Z has a pvalue of 0.1, so X when Z = -1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.28 = \frac{X - 325}{10}[/tex]

[tex]X - 325 = -1.28*10[/tex]

[tex]X = 312.2[/tex]

Below 312.2 grams

Given numbers are :

0.30 cm and 0.42 cm

We need to find the ratio of the above whole numbers.

Taking 0.3 cm on the numerator and 0.42 cm on the denominator. So,

[tex]\dfrac{0.3}{0.42}=\dfrac{\dfrac{3}{10}}{\dfrac{42}{100}}\\\\=\dfrac{3}{10}\times \dfrac{100}{42}\\\\=\dfrac{10\times 3}{42}\\\\=\dfrac{10}{14}\\\\=\dfrac{5}{7}[/tex]

So, the required fraction is equal to [tex]\dfrac{5}{7}[/tex].

The original price of the play station is $620.

Given that, the cost of the play station=$558 and discount=10%.

We need to find the original price of the play station.

The definition of discount is reduced prices or something being sold at a price lower than that item is normally sold for.

Let the original price be x.

Now, x-10% of x=558

⇒x-0.1x=558

⇒0.9x=558

⇒x=$620

Therefore, the original price of the play station is $620.
