Step-by-step explanation:

6n=150

Answer:

Yes, it appears so.

Step-by-step explanation:

Based on the fact that angle L and angle P are congruent, the angles at point M are also congruent to their opposites. All of this points to triangles MNP and MLK being the same, which would mean that x does equal 15. Sorry I couldn't state any specific laws or anything.

Answer:

$18.50

Step-by-step explanation:

$49.50/3months=$16.50

$16.50+$2=$18.50

Malik joins a gym, then the gym's regular monthly rate will be equal to $18.50.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.

Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given information in the question,

Price paid by Malik in three months = $49.50

Then, monthly price will be,

$49.50/3months = $16.50

Then, the gym's regular monthly rate will be,

$16.50 + $2 = $18.50

Answer:

A. 84 pi feet^2

Step-by-step explanation:

So the lateral area is the rectangular piece on the net

In order for it to be an actual cylinder the 2 circles are congruent

Therefore the radi, area, circumference ect.. are the same.

So the only missing measurement we need to find the lateral area is the length of the rectangular piece

If you visualize a cylinder, the rectangular piece goes around the perimeter/circumference of the circle

So that means that the length of the rectangle is the circumference of the circle

Circumference = 2*pi*r

2 * pi * 6

= 12 pi

Then 7*12 pi

=84 pi

So the lateral area is 84 pi

Answer:

the inside angle beside 101 is 180-101 = 79 degrees.

the angle beside x = 180-(79+38).

that is 63 degrees.

therefore the angle x = 180-63 that's

Answer:

Positive slope- line B

negative y-intercept- line C

slope of 0- line C

Step-by-step explanation:

Positive slope- line B This is because the line is angled upward on the right side

negative y-intercept- line C- the line is below the (0,0) mark

slope of 0- line C This is because the line isn’t angle upward nor downward.

The estimated mean of advertising expenses is $52 million, and the estimated standard deviation is $11.23 million.

To estimate the mean and standard deviation of advertising expenses, we need to calculate the midpoint of each class interval, the product of the midpoint and the frequency, and the squared deviation from the mean.

Here's a table to organize the calculations:

Class Interval (x)     Frequency (f)     Midpoint (x)       fx

25 up to 35                   5                       30                 150

35 up to 45                   10                      40                 400

45 up to 55                   21                      50                1,050

55 up to 65                   16                      60                 960

65 up to 75                   8                        70                  560

To calculate the mean, we need to find the sum of the products of the midpoint and the frequency, divided by the total frequency.

Mean = (fx) / Total Frequency

Mean = (150 + 400 + 1,050 + 960 + 560) / 60

Mean = 3,120 / 60

Mean = 52

Calculate the squared deviation from the mean for each class interval.

(x - mean)² × f

(30 - 52)² × 5 = 484 × 5 = 2,420

(40 - 52)² × 10 = 144 × 10 = 1,440

(50 - 52)² × 21 = 4 × 21 = 84

(60 - 52)² ×  16 = 64 × 16 = 1,024

(70 - 52)² ×  8 = 324 × 8 = 2,592

Calculate the sum of the squared deviations.

Sum of (x - mean)× f = 2,420 + 1,440 + 84 + 1,024 + 2,592

= 7,560

Standard Deviation =√(Sum of (x - mean)² × f / Total Frequency)

Standard Deviation = √(7,560 / 60)

Standard Deviation = √(126)

Standard Deviation = 11.23

Hence, the estimated mean of advertising expenses is approximately $52 million, and the estimated standard deviation is approximately $11.23 million.

Answer:

Normality assumptions are met.

The 90% confidence interval for the proportion of adult drivers that run at least one red light in the last month is (0.4892, 0.5356). The interpretation is that we are 90% sure that the true proportion of all adult drivers than ran at least one red light in the last month is between these bounds.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Out of 1251 adult drivers, 641 of them have run at least one red light in the last month.

This means that [tex]n = 1251, \pi = \frac{641}{1251} = 0.5124[/tex]

Normality assumptions:

We need that: [tex]n\pi[/tex] and [tex]n(1-\pi)[/tex] are 10 or greater. So

[tex]n\pi = 1251*0.5124 = 641[/tex]

[tex]n(1-\pi) = 1251*0.4876 = 610[/tex]

So the normality assumptions are met.

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 - 1.645\sqrt{\frac{0.5124*0.4876}{1251}} = 0.4892[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 + 1.645\sqrt{\frac{0.5124*0.4876}{1251}} = 0.5356[/tex]

The 90% confidence interval for the proportion of adult drivers that run at least one red light in the last month is (0.4892, 0.5356). The interpretation is that we are 90% sure that the true proportion of all adult drivers than ran at least one red light in the last month is between these bounds.

Step-by-step explanation:

The Hypotenuse of triangle, H = 25 cm

Base = 15 cm

Height = 20 cm

We need to find the area of the triangle. The area of a right-angled triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 15\times 20\\A=150\ cm^2[/tex]

So, the area of the triangle is equal to [tex]150\ cm^2[/tex].
