Can Someone Help Me Find The Values Of Y And Z?

Answers

Answer 1

Answer:

y= 134.5 and z= 44.5 :)

Step-by-step explanation:

6z-87=180

6z=267

267/6=44.5

180-44.5=134.5

Answer 2

Answer:

y=99, z=81

Step-by-step explanation:

the angle above y is corresponding to 81, so if you substitute 81 in that place then it'll be angles on a straight line;

81 + y =180

(add like terms)

y =180 - 81

=99.

thus, y is 99. Once you do that, y and z are on a straight line so you solve for x using the formula for angles on a straight line;

y + (6z - 87)

(substitute y with 99)

99 + 6z - 87 =180

6z + 12 =180

(add like terms)

6z =180-12

6z =168

(divide both sides by six)

6z /6= 168/6

z = 28

(then you solve everything that was in the bracket for z)

(6z - 87)

(substitute z with 28)

=6 × 28 - 87

=168 - 87

=81

therefore, y =99 and z =81

Thanks :)

Answers

Answer:

w = - 15

Step-by-step explanation:

Assuming you mean

[tex]\frac{w+3}{3}[/tex] = - 4 ( multiply both sides by 3 to clear the fraction )

w + 3 = - 12 ( subtract 3 from both sides )

w = - 15

Answer:

w= -5

Step-by-step explanation:

w+3/3= -4

w= -4-1... which is  (-4) + (-1) so,

w= -5

Answers

Answer: 4.15 degrees

Step-by-step explanation:

Refer to the data set of 20 randomly selected presidents given below. Treat the data as a sample and find the proportion of presidents who were taller than their opponents. Use that result to construct a​ 95% confidence interval estimate of the population percentage. Based on the​ result, does it appear that greater height is an advantage for presidential​ candidates? Why or why​ not?

Answers

Complete Question

The data for this question is shown on the first uploaded image

Answer:

The 95% confidence interval estimate of the population percentage is  

   [tex] 33.2\% <  p < 76.8 \% [/tex]

Step-by-step explanation:

On the data the first value is the height of the president while the other value is the height of his opponent

    The sample size is  n  =  20  

Looking at the data we see that out of the 20  presidents that only 11 is taller than their opponent

 So the proportion of presidents that are taller than their opponents is  

      [tex]\^ p = \frac{11}{20}[/tex]  

=>   [tex]\^ p = 0.55[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of   is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

   [tex]E = Z_{\frac{\alpha }{2} } *  \sqrt{\frac{\^ p (1- \^ p) }{n}} [/tex]

  [tex]E = 1.96 *  \sqrt{\frac{0.55 (1- 0.55) }{20}} [/tex]

   [tex]E = 0.218[/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex]\r p -E <  p <  \r p +E[/tex]

=>    [tex]0.55-0.218 <  p < 0.55+ 0.218 [/tex]

=>    [tex]0.332 <  p < 0.768 [/tex]

Converting to percentage

        [tex](0.332*100)\% <  p < (0.768 *100) \% [/tex]

=>    [tex] 33.2\% <  p < 76.8 \% [/tex]

Step-by-step explanation:

find the vector from A to A'  or any of the other non prime to prime points.. the vector will be the same...  soooo

take the origin point as P1 , then take the destination point a P2

and subtract P2-P1

P2 = A' = (6,-2)

P1 = A = (2, 1)

(6-2, -2-1) = (4,-3)

your vector can be place at the origin.. and go 4 in the x direction and -3 in the y direction and you get that translation.. make sense?

A leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours. After the leak is fixed, the height of the water is 4.75 feet. The equation 4.75 = x + (negative 0.25) can be used to find x, the original height of the water in a pool.

What was the original height of the water in the pool in feet?

Answers

Answer:

Assuming the leak took 2 hours to fix, the original height of the pool is 5 feet.

Step-by-step explanation:

This is probably the most simple "high school" problem I've seen in a while. All you have to do is move the negative 0.25 to the other side to isolate x. That gives you 4.75 + 0.25, or 5 feet.

The original height of the water in the pool was 5 feet.

Given that there is leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours.

After the leak is fixed, the height of the water is 4.75 feet.

The equation 4.75 = x - 0.25 can be used to find x, the original height of the water in a pool.

we need to find the original height of water,

To find the original height of the water in the pool, we can use the given information and equation.

Let's break down the equation: 4.75 = x - 0.25

Here, x represents the original height of the water in the pool, and -0.25 represents the decrease caused by the leak.

The equation states that after the leak is fixed, the height of the water in the pool is 4.75 feet. This means that the final height (4.75 feet) is equal to the original height (x) minus the decrease caused by the leak (-0.25 feet).

To solve for x, we can isolate it on one side of the equation.

Adding 0.25 to both sides of the equation, we get:

4.75 + 0.25 = x - 0.25 + 0.25

Simplifying the equation, we have:

5 = x

Therefore, the original height of the water in the pool was 5 feet.

Sadie has $1 worth of nickels and dimes. She has twice as many nickels as dimes. Write a system of equations that could be used to determine the number of nickels and the number of dimes that Sadie has. Define the variables that you use to write the system.

Answers

N + 2d =1
This is the system of equations because it is 2 times more than nickels

The system of equations which can be used to model the scenario are :

n = 2d _____________(1)

0.05n + 0.10d = 1 _____(2)

Let :

Number of dimes = d

Number of nickels = n

Number of nickels = 2 × number of dimes

n = 2d - - - - - (1)

Worth of nickels and dimes:

A dime = $0.10A nickel = $0.05

The total worth of nickel and dimes can be expressed thus :

(Worth per nickel × number of nickels) + (worth per dime × number of dimes)

(0.05 × n) + (0.10 × d) = 0.05n + 0.10d = 1

What is the equation of a line that passes through the point (-7,-8) and parallel to y=5/7x-5.

Answers

Answer:

The equation of the line that passes through the point (-7, -8) and parallel to the given line is y = 5/7·x - 3

Step-by-step explanation:

The coordinates of the point the line passes = (-7, -8)

The equation of the line the required line is parallel to is y = 5/7·x - 5

The slope of of the given line is therefore in slope and intercept form with the slope = 5/7 and the y-intercept = -5

The slope of a line parallel to another line are equal, therefore the slope of the required line = The slope of the given line = 5/7

The equation of the required line in point slope form is therefore;

y - (-8) = 5/7 × (x - (-7))

y + 8 = 5/7 × x + 5/7 × 7

y + 8 = 5/7 × x + 5

∴ y = 5/7 × x + 5 - 8 = 5/7 × x - 3

y = 5/7 × x - 3

The equation of the line that passes through the point (-7, -8) and parallel to y = 5/7x - 5 is y = 5/7·x - 3.

A numerical expression is a form where we express a statement by number and their operations.

According to the given phrase six times the quantity four which is 6(4) plus a number.

6(4) + n.

What we have done here is we formed a numerical expression from a given statement.

Suppose we have given sum of 4 and thrice of a number is 10.

Answer:

[tex]y=\frac{1}{2}x+2[/tex]

Step-by-step explanation:

To find the equation for the line, lets try to find the slope and y-intercept of the line.

From looking at the graph, we can see that the line intersects the y-axis at y = 2. So the y-intercept would be 2.

The slope of the line would be the rise divided by the run. Looking at the graph, we can see that for every 2 the line moves in the x-direction, it moves 1 in the y-direction. This means that the rise is 1 and the run is 2. So the slope would be 1/2.

So we now know that the slope is 1/2 and the y-intercept is 2, we can now plug the information into the slope-intercept form.

Slope-intercept form is:

y = mx + b

where m is the slope and b is the y-intercept.

Plugging in we get

[tex]y=\frac{1}{2}x+2[/tex]

And now we have the equation of the line.
