Answers
Answer:
W = x^2 - 2yz / - w
0 = x^2 - 2yz - w / +2yz
2yz = x^2 - w // 2z
y = (x^2 -w ) / 2z
So correct answer is D

For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 37 beats per minute, the mean of the listed pulse rates is x=71.0 beats per minute, and their standard deviation is s=18.2 beats per minute. a. What is the difference between the pulse rate of 37 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the pulse rate of 37 beats per minutes to a z score. d. If we consider pulse rates that convert to z scores between −2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 37 beats per minute significant?
Answers
Answer:
See below.
Step-by-step explanation:
(a) Difference = 71 - 37 = 34 beats/minute.
(b) Number of standard deviations = 34 /18.2 = 1.868.
(c) z score = (x - m )/ s where m = mean and s = standard deviation
= (37 - 71) / 18.2 = -1.868.
(d) This z score lies between -2 and 2 so a pulse rate of 37 is not significant.

Find the exact length of the third side. 95 n 76
Answers
Answer:
121.66
Step-by-step explanation:
To solve, use the Pythagorean Theorem, which says c² = a² + b². Enter 95 as a and 76 as b and square them both. This will give you 9025 for a, and 5776 as b. Add them to get 14,801. So, c² = 14,801. Find the square root of this to get approximately 121.66. So, the third side is about 121.66 in length.

What is 22 lb day in oz h?
Answers
Answer:
352 OZ
Step-by-step explanation:
One pound = 16 OZ
take 22 and multiply it by 16
22 x 16 = 352
Answer:
15 ounces per hour
Step-by-step explanation:
This is dimensional analysis, so we need to find conversion factors for ounces per pound and hours per day. Once we have those we write the equation such that the units we need are left and the others cancel:
22lb/1 day x 16 ounces/1 lb x 1 day/24hrs = 14.66666666666 ounces per hour
Since the problem was written with no decimals, our answer probably shouldn't either and in most cases like this we want to round to the nearest whole number, which is 15.

Answers
Answer:6
-3y= 6 - 2x
Answer:
y=-2x-2
Step-by-step explanation:
Parallel means the same slope from the given slope in the statement.
To find the slope-intercept form equation, you must use the point-slope form which is y-y1=m(x-x1).
The given point (0, -1) includes 0 as the x-intercept and -1 as the y-intercept.
Because parallel is the same slope, the slope we'll insert into our equation is -2.
The point-slope form substituted with the given point and slope looks like the following:
y-(-1)=-2(x-0) which can be simplified to y+2=-2x+0
Solve the simplified equation.
y+2=-2x+0
-2 -2
y=-2x-2
That's the final equation.

∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+10)^{\circ}∠A=(7x+10) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ , then find the measure of \angle A∠A.
Answers
Answer:
108 degrees
Step-by-step explanation:
Since angles A and B are supplementary, they both add up to 180. Angle A = 7x+10, and angle B = 7x-26. You can set up the equation A + B = 180, and then plug in angles A and B, which gives you 7x+10 + 7x-26 = 180. Then you just need to isolate x:
Combine like terms: 14x - 16 = 180
Add 16 to both sides: 14x = 196
Divide both sides by 14: x = 14
Now that you know x, you can plug it into the expression for angle A (7x+10):
A = 7(14) + 10 = 98+10 = 108

Marc sold 500 tickets for the school play. Student tickets cost $2 and adult tickets cost $5. Marc's sales totaled $1,789. a) Write a system of equations that can be used to determine how many of each type of ticket Marc sold b) Solve the system to determine how many adult tickets and how many student tickets Marc sold.
Answers
Answer:
a) System of equations will be: [tex]x+y=500\: and\:5x+2y=1789[/tex]
b) Number of adult tickets sold = 263
Number of students tickets sold = 237
Step-by-step explanation:
Let:
Number of adult tickets sold = x
Number of students tickets sold = y
a)
As Marc sold total 500 tickets, the expression will be: [tex]x+y=500[/tex]
Student tickets cost $2 and adult tickets cost $5. Marc's sales totalled $1,789.
The expression will be: [tex]5x+2y=1789[/tex]
So, system of equations will be: [tex]x+y=500\: and\:5x+2y=1789[/tex]
b)
Solve the system to find value of x and y
Let:
[tex]x+y=500--eq(1)\\5x+2y=1789--eq(2)[/tex]
Multiply equation 1 by 2 and subtract
[tex]2x+2y=1000\\5x+2y=1789\\-\:\:\:-\:\:\:\:\:\:\:\:\:-\\------\\-3x=-789\\x=\frac{-789}{-3}\\x=263[/tex]
We get value of x = 263
Now finding value of y by putting value of x in eq(1)
[tex]x+y=500\\263+y=500\\y=500-263\\y=237[/tex]
We get value of y = 237
Number of adult tickets sold = x = 263
Number of students tickets sold = y = 237
