Find the slope of a line parallel to each given line. y=-5/3x+5

Answers

Answer:

m= -5/3

Step-by-step explanation:

M= slope

To find slope, you do y= mx + b

Answer:

[tex]\boxed {\boxed {\sf m= -\frac{5}{3}}}[/tex]

Step-by-step explanation:

First, identify the slope of the line given.

[tex]y= -\frac{5}{3}x+5[/tex]

This line is in slope-intercept form or y=mx+b where m is the slope and b is the y-intercept. The number being multiplied by x is the slope. The number being added or subtracted is the y-intercept.

-5/3 is the coefficient to x (-5/3 and x are being multiplied). So, the slope must be -5/3.

Next, remember that parallel lines have equal slopes. If the line is parallel to y= -5/3x+5, the slope must also be -5/3.

the sides lenghths of a triangle are 9, 12, and 18 is this a right triangle?​

Answers

Answer:

By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.

For the 1,000-meter running event, Abby's mean time is 4.5 minutes with a standard deviation of 0.75 minutes. For the 800-meter event, Abby's mean time is 3.2 minutes with a standard deviation of 0.4 minutes. In the last track meet, Abby ran the 1,000-meter race in 4.1 minutes and the 800-meter race in 3 minutes. In which event did Abby have a better performance?

Answers

Answer:

He performed better in the 800 m race

Step-by-step explanation:

Obtain the standardized score for each event :

Zscore = (score - mean) / standard deviation

1000 meter :

Mean = 4.5 ; Standard deviation = 0.75 ; x = 4.1

Zscore = (4.1 - 4.5) / 0.75

Zscore = - 0.4 / 0.75 = - 0.5333

800 meter :

Mean = 3.2 ; Standard deviation = 0.4 ; x = 3

Zscore = (3 - 3.2) / 0.4

Zscore = - 0.2 / 0.4 = - 0.5

-0.5 > - 0.533

Hence, he performed better in the 800 m race

Answer:

Abby had a better performance in the 800-meter because this z-score was closer to the mean than the z-score for the 1,000-meter.

A ​17-foot ladder is placed against a vertical wall of a​ building, with the bottom of the ladder standing on level ground feet from the base of the building. How high up the wall does the ladder​ reach?

Answers

Answer:

15 feet..

taking base as 8m

Given: ladder = 17 m and base = 8 m

The ladder forms a right triangle with the base of 8 m, the wall will be 15 m and the ladder (hypotenuse) is 17 m.

Let’s say you did not know that this was a standard 8–15–17 right triangle.

This is how you can figure it out:

hypotenuse(h)22 = side2112 + side2222

Let side11 = base and side22 = wall

1722 = 822 + wall22

wall = 172−82−−−−−−−√172−82

wall = 289−64−−−−−−−√289−64

wall = 225−−−√225

wall = 15 feet

Height of wall is 15 feet

Given:

Length of ladder = 17 feet

Base distance from ladder = 8 feet (Missing information)

Find:

Height of wall

Computation:

Length of ladder = hypotenuse

Base distance from ladder = Base

Height of wall = Perpendicular

Using Pythagorean theorem

[tex]Perpendicular = \sqrt{Hypotenuse^2 - Base^2}[/tex]

By putting values

[tex]Perpendicular = \sqrt{17^2 - 8^2}[/tex]

[tex]Perpendicular = \sqrt{289 - 64} \\\\Perpendicular = \sqrt{225} \\\\Perpendicular = 15[/tex]

Height of wall = 15 feet

Help please.

Answers

Answer:

X actually equals 16 becaausw if yiu add 16+4 you get 20 and then you have to multiply 20 by 1 and you get 20 so x=16

Answer:

x = 16

I dont quite understand the x = 48 situation? But thats wrong if that's your answe

Step-by-step explanation:

So you have to find out what x is

in order to do that you have to work out the equation and whatever you do to one side you must do to the other side

simplify 1(x+4) = 20

x + 4 = 20

in order to get rid of 4 on one side you have to subtract it on both sides

so x = 16

In 1999, Quinn et al studied the relation between myopia and ambient lighting at night (for example, from nightlights or room lights) during childhood.Question 1. The data were gathered by the following procedure, reported in the study. "Between January and June 1998, parents of children aged 2-16 years [...] that were seen as outpatients in a university pediatric ophthalmology clinic completed a questionnaire on the childs light exposure both at present and before the age of 2 years."

The study found that of the children who slept with a room light on before the age of 2, 55% were myopic. Of the children who slept with a night light on before the age of 2, 34% were myopic. Of the children who slept in the dark before the age of 2, 10% were myopic.

Studying the SurvivorsThe Reverend Henry Whitehead was skeptical of John Snows conclusion about the Broad Street pump. After the Broad Street cholera epidemic ended, Whitehead set about trying to prove Snow wrong. (The history of the event is detailed here.)He realized that Snow had focused his analysis almost entirely on those who had died. Whitehead, therefore, investigated the drinking habits of people in the Broad Street area who had not died in the outbreak.What is the main reason it was important to study this group?1) If Whitehead had found that many people had drunk water from the Broad Street pump and not caught cholera, that would have been evidence against Snow's hypothesis.2) Survivors could provide additional information about what else could have caused the cholera, potentially unearthing another cause.3) Through considering the survivors, Whitehead could have identified a cure for cholera.In [ ]:# Assign survivor_answer to 1, 2, or 3survivor_answer = ...In [ ]:_ = ok.grade('q7_1')Note: Whitehead ended up finding further proof that the Broad Street pump played the central role in spreading the disease to the people who lived near it.
