.

Answers

Answer 1

Answer:

[tex]Median = 13[/tex]

Step-by-step explanation:

Given

See attachment for dot plot

Required

The center of data

This implies that, we calculate the median

From the attached plot,

[tex]n = 13[/tex] --- number of observation

So, the median is:

[tex]Median = \frac{n + 1}{2}[/tex]

[tex]Median = \frac{13 + 1}{2}[/tex]

[tex]Median = \frac{14}{2}[/tex]

[tex]Median = 7th[/tex]

The median is at the 7th position

At the  7th position, is 13

Hence:

[tex]Median = 13[/tex]

350 people watched a beauty contest. Some paid GH¢20.00 each while others paid GH¢30.00 each. The total amount collected was GH¢8,800.00. Find how many paid the two different rates.

Answers

Answer: 170 people paid GH¢20 and 180 people paid GH¢30

Step-by-step explanation:

Let the number of people that paid GH¢20 be represented by x.

Let the number of people that paid GH¢30 be represented by y.

Based on the above information given, we can form an equation which will be:

x + y = 350 ....... i

20x + 30y = 8800 ....... ii

Multiply equation i by 20

20x + 20y = 7000 ...... iii

20x + 30y = 8800 ...... iv

Subtract iii from iv

10y = 1800

y = 1800/10

y = 180

Since x + y = 350

x = 350 - y.

x = 350 - 180

x = 170

Therefore, 170 people paid GH¢20 and 180 people paid GH¢30

Derrick started a new job at McDonald's. He makes $10 per hour. Which
equation models his total weekly earnings y, in terms of the number of
hours he works x? *

Answers

Answer:

10x=y.

Step-by-step explanation:

10 represents the amount he earns an hour. X represents the number of hours so 10x. 10 times the amount of hours equals y (total amount of money)

Answer:

y = 10x

Step-by-step explanation:

The total earnings, y, is equal to the hourly rate, 10, times x, the hours worked.

y equals 10 times x, or, in equation form, y = 10x.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 26 inches, and the length of the base is 18 inches. Find the triangle's perimeter. Round to the nearest tenth of an inch.

Answers

Answer:

if it was 29inches it would be 78.7

Step-by-step explanation:

The given altitude and the base length of the triangle can be used for

finding the lengths of the other two sides.

The perimeter of the triangle is approximately 73.0 inches

Reasons:

The altitude is the perpendicular bisector of the base of the triangle

Length of the altitude = 26 inches

Length of the base of the triangle, b = 18 inches

Required:

The perimeter of the triangle

Solution:

The base length of the two congruent triangles formed are [tex]\dfrac{18 \, cm}{2}[/tex] = 9 cm

each.

Therefore;

The length of the hypotenuse side, L, is given by Pythagoras's theorem as

follows;

L² = 9² + 26² = 757

The hypotenuse side, L = The length of the equal sides of the isosceles triangle

Therefore, the perimeter of the triangle, P = b + 2·L

Which gives;

To the nearest tenth, the perimeter of the triangle, P = 18 + 2·√(757) ≈ 73.0

The perimeter of the triangle, P ≈ 73.0 inches

In a congressional district, 55% of the registered voters are Democrats. Which of the following is closest to the probability of getting less than 50% Democrats in a random sample of size 100?
Is this an example of a sample proportion OR a sample mean?

Answers

Answer:

sample mean

Step-by-step explanation:

Using the normal distribution and the central limit theorem, considering that this is a sample proportion, as we are dealing with percentages, it is found that there is a 0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.

Normal Probability Distribution

In a normal distribution 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]

It 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, which is the percentile of X. By the Central Limit Theorem, the sampling distribution of sample proportions of a proportion p in a sample of size n has mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex].

In this problem:

55% of the registered voters are Democrats, hence [tex]p = 0.55[/tex].A sample of size 100 is taken, hence [tex]n = 100[/tex]

The mean and the standard deviation of the sampling distribution of sample proportions are given by:

[tex]\mu = p = 0.55[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.55(0.45)}{100}} = 0.04975[/tex]

The probability of getting less than 50% Democrats in a random sample of size 100 is the p-value of Z when X = 0.5, hence:

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

By the Central Limit Theorem

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

[tex]Z = \frac{0.5 - 0.55}{0.04975}[/tex]

[tex]Z = -1.01[/tex]

[tex]Z = -1.01[/tex] has a p-value of 0.1562.

0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.

Megan's age is three years more than four times her daughter's age. If Megan's daughter's age is $d$ , Megan's age is

Answers

Answer: 4d + 3

Step-by-step explanation:

Megan's daughter's age = d

Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:

= (4 × d) + 3

= 4d + 3

Therefore, Megan's age is 4d + 3.

For example, if the daughters age is 7 years, Megan's age will be:

= 4d + 3

= 4(7) + 3

= 28 + 3

= 31 years

What two numbers multiply to get 18 but add to get -12

Answers

Answer:

-6+3[tex]\sqrt{2}[/tex] and -6-3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

xy = 18

x+y = -12

y = -12-x

x(-12-x) = 18

-12x - x² - 18 = 0

-x² - 12x - 18 = 0

-(x² + 12x + 18) = 0
