If QRS = MNP, QR = 11, QS = 15, MP = 2x + 1, S = 84, R = 32, and M = (17y - 4),

find the values of x and y.

pls answer quick

Answers

Answer:

x = 7 and y = 4

Step-by-step explanation:

If QRS = MNP, then QR = MN, RS = NP and QS = MP

Given

QR = 11

QS = 15

MP = 2x + 1

Recall that QS = MP

15 = 2x+1

2x = 15-1

2x = 14

x = 14/2

x = 7

Similarly

<Q = <M

<Q + <R + <S = 180

<Q + 32 + 84 = 180

<Q + 116 = 180

<Q = 180 - 116

<Q = 64 degrees

Since <M = 17y - 4

64 = 17y - 4

17y = 64+4

17y = 68

y = 68/17

y = 4

Hence x = 7 and y = 4

Write an expression for the age of:
Her mum

Answers

Answer:

Ebony's brother is x + 4 years old.

Ebony's mum is 3x years old.

Explanation:

Since Ebony is x years old, and her brother is 4 years older than her, the expression is x + 4, as her brother is +4 years older.

Ebony's mum is 3 times Ebony's age, which is x. 3 times x is shortened into 3x.

Answers

Answer:

the x and y is 6 and -4 respectively

Step-by-step explanation:

The computation of solving the system of equations is given below:

Given that

5x - 7y = 58

And,

y = -x + 2

Put y value in the first equation

5x - 7(-x + 2) = 58

5x + 7x - 14 = 58

12x = 58 + 14

12x = 72

x = 6

So y = -6 + 2

= -4

Hence, the x and y is 6 and -4 respectively

Answers

Answer:

The population is: all glass recycled

The sample is: the 10 selected glass items.

The parameter is the proportion of: all his glass that is clear

The statistic is the proportion of: the selected glass that is clear

The population of a distribution is the entire group, while the sample is the selected group from the entire group.

The population is all glass recycled The sample is the 10 selected glass items. The parameter is the proportion of all his glass that is clear The statistic is the proportion of the selected glass that is clear

The population

From the question, we understand that glasses are recycled and then separated into colors.

This means that, the population is all glass recycled

The sample

From the question, we understand that he randomly grabs 10 glass items, and then determine the proportion of clear glasses.

This means that, the sample is the 10 selected glass items.

The parameter

This is the value that summarizes all the glasses that are being recycled.

So, the parameter is the proportion of all his clear glasses

The statistic

This is the value that summarizes the selected glasses.

So, the statistic is the proportion of the selected glass that is clear

A polling company plans to create a probability model for a state election. In a telephone survey of 750 residents who stated they were registered to vote, they found that 318 planned to vote for the Democratic candidate, 268 planned to vote for the Republican candidate, with the remainder were undecided. What is a reasonable probability model for the state election?

Select the correct ANSWERS from the list below

54% plan to vote for the Democratic candidate|

22% are undecided.

18% are undecided.

36% plan to vote for the Republican candidate.

46% plan to vote for the Republican candidate.

42% plan to vote for the Democratic candidate


this decides my grade please only answer if you know it

Answers

Answer:

22% are undecided

36% plan to vote Republican

42% plan to vote Democratic

Step-by-step explanation:

Take 318 and divide it by 750 to find the democratic vote. Round to the nearest whole number.

318/750 = 0.424

Same for Republican except take 268 and divide by 750.

268/750 = 0.357

Add both percentages together. 36% + 42% = 78%

So there is 22% of the population that either did not answer or are undecided.

The correct answers are:

22% are undecided

36% plan to vote Republican

42% plan to vote Democratic

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Total Resident = 750

Out of which 318 planned to vote for the Democratic candidate, 268 planned to vote for the Republican candidate.

So, 318/750 = 0.424

                    = 42.4%

and, 268/750 = 0.357

                       = 35.7%

So, the percentage who decided to vote = 36% + 42% = 78%

Hence, there is 22% of the population that either did not answer or are undecided.

Stacia has 28 red and blue marbles. The ratio of red to blue marbles is 1:6. How many blue marbles does Stacia have?

Answers

Answer:

The total number of blue marbles = 24

Step-by-step explanation:

Total number marbles Stacia has = 28

The ratio of red to blue marbles = 1 : 6

Let 'r' be the number of red marbles.Let 'b' be the number of blue lines

As the total number of marbles is 28. Thus,

r + b = 28

As the ratio of red to blue marbles is 1 to 6.

It means for each red marble 'r', we have 6 blue 'b' marbles. Thus,

b = 6r

now substituting b = 6r in the equation r + b = 28

r + b = 28

r + 6r = 28

7r = 28

divide both sides by 7

7r/7 = 28/7

r = 4

Thus,

The total number of red marbles ⇒ r = 4

The total number of blue marbles ⇒ b = 6r = 6(4) = 24

Therefore,

The total number of blue marbles = 24
