Answer:
x=1 ,y=-5
Step-by-step explanation:
3x + 10y = 47
5x - 7y = 40
____________
21x + 70y = 329. equ 1
50x - 70y = 400. equ 2
subtract equ 1 from 2
=71x = 71
divide both sides by the 71
71/71 = 71/71
x = 1
_________
to find y
substitute x into either equ 1 or equ 2
am using equ 2
5x - 7y = 40
5(1) - 7y = 40
5 - 7y = 40
7y = 5 - 40
7y = -35
divide both sides by the coffecient of y

What's Yo Question ?
Suppose a hawk can fly 78 miles in 3 hours. An owl can fly 99 miles in 4 hours. Which raptor can fly faster and by how much?
Answers
Answer:
The Hawk can fly faster
Step-by-step explanation:
First, take 78/3 that will give you the miles per hours the hawk flys.
78/3 = 26 miles/ per hour
Then, do the same for the owl.
99/4 = 24.75 miles an hour.
To find out how much faster the hawk in than the owl suntract the owls miles per hour from the hawks miles per hour.
24.75 - 26 = 1.25 miles faster
The conversion of ammonium cyanide to urea is a second-order reaction. This means that the concentration C of ammonium cyanide at time t is given by 1/C = kt + 1/C0, where C0 is the initial concentration and k is the rate constant. Assume the initial concentration is known to be 0.1 mol/L exactly. Assume that time can be measured with negligible uncertainty.
a. After 45 minutes, the concentration of ammonium cyanide is measured to be 0.0811 ? 0.0005 mol/L. Estimate the rat? constant k, and find the uncertainty in the estimate.
b. Use the result in part (a) to estimate the time when the concentration of ammonium cyanide will be 0.0750 mol/L, and find the uncertainty in this estimate.

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 37 ounces and a standard deviation of 7 ounces. Use the Empirical Rule, also known as the 68-95-99.7 Rule. Do not use Tables or Technology to avoid rounding errors. Suggestion: sketch the distribution in order to answer these questions. a) 68% of the widget weights lie between and b) What percentage of the widget weights lie between 23 and 44 ounces
Answers
Answer:
a) 68 % will lie between 30 and 44 ounces
b) between 23 and 44 ounces will lie 81,5 %
Step-by-step explanation: See Annex
a) Normal Distribution N ( 37, 7)
The Empirical Rule establishes that 68 % of values will be at
μ ± 1 σ where μ is the mean and σ the standard deviation
Then: 37 - 7 = 30 and 37 + 7 = 44
68 % of the values will lie between 30 and 44 ounces
b) And between 23 and 44 we should find:
We have 95 % of values between
μ ± 2*σ
In our case to the left of the value (mean 0 ) and up to the value 23 we get 95/2 = 47,5 % and to the right of the value (mean 0 ) and up to 44 we half 68/2 = 34 %
Then between 23 and 44, we have 47,5 + 34 = 81,5 %

If your car gets 28 miles per gallon and you travel 30 miles round-trip to work five days a week, how much do you pay each 4-week
month if gas is $3.05 a gallon? (Round your answer to 2 decimal places.)
please help
Answers
Answer:
You'd pay $65.35 every 4 weeks
Step-by-step explanation:
First you have to gather all the miles.
30 miles x 5 = 150
So that is 150 miles/per week
Then you have to devide the miles by how many gallons per gas you travle.
150/28 miles per gallon = 5.3571....
That how many gallons you'll need a week.
Now, you times the gallons by the price of the gas
5.3571... x $3.05 = $16.3392...
Finally you times the amoutn of money for a week time 4 weeks.
$16.3392... x 4 = $65.35 (to the two decimal mark)
Hope this helped you! : )
A student taking a Calculus class makes the following statement:
”If f(1) > 0 and f(3) < 0, then there exists a number c, between 1 and 3 such that f(c) = 0.”
Is the statement true? If it’s true, explain why, if it is false, explain why, or give an example that disproves it.
Answers
Explanation:
Imagine that f(x) was a road without any gaps. The road can be straight or it can be curved somehow.
Now imagine that a horizontal line is the border between two countries. The country up north is the positive country and the southern country is negative.
f(1) > 0 means we're in the northern country since f(x) is positive here
then f(3) < 0 means we're now in the southern negative country
Somewhere along the road we must have crossed the border at least one time. This must be the case because the road does not have any gaps in it and we cannot teleport. This is what it means to be a continuous function. To draw a continuous curve, you cannot lift your pencil up.
So because f(x) transitions from positive to negative, this means f(x) = 0 at some point at least once. So that's why there exists a c such that f(c) = 0

Answers
Answer:
(a) [tex]\hat y=69.04-0.083\cdot x[/tex]
(b) D. For every unit increase in commute time, the index score falls by 0.083, on average.
Step-by-step explanation:
(a)
Form the least-squares regression line using Excel as follows:
Go to Data → Data Analysis → Regression
A dialog box will open.
Select the X and Y variable.
Press Ok.
The regression output is attached below.
The least-squares regression line is:
[tex]\hat y=69.04-0.083\cdot x[/tex]
(b)
The slope of a regression line is the average rate of change in the dependent variable (y) with 1 unit change in the independent variable (x).
Here the slope value is -0.083. This value implies that with 1 minute change in the commute times the Well-Being Index Score falls by 0.083 units.
The intercept of a regression line is the average value of the dependent variable (y) when the independent variable (x) value is 0.
Here, the intercept value is 69.04. This value implies that for a person with commute time 0, their Well-Being Index Score is 69.04.
The correct option is:
D. For every unit increase in commute time, the index score falls by 0.083, on average.

Last week she worked 43 hours.
a. What is her regular gross pay?
b. What is her hourly overtime rate?
c. What was her overtime pay?
d. What was her total pay for the week?
Answers
Answer:
Step-by-step explanation:
gross pay = 640
hourly overtime rate= 24
Overtime pay= 72
Total pay for the week= 712
Her regular gross pay is 640. the hourly overtime rate is 24. Overtime pay= 72 and Total pay for the week= 712
What is Regular gross pay ?Regular gross pay is that pay which the person earn on daily basis or it is a fixed amount which he gets after completing a month.
Here, We have to find out the regular gross pay which includes the daily earning of a person.
Lynda regularly works a 40-hour work week and earns $16.00 per hour.
So, her regular gross pay = number of hours × rate per hour
= 40 × $16
= $640
Hence, the gross pay = 640
Her regular gross pay is 640. the hourly overtime rate is 24. Overtime pay= 72 and Total pay for the week= 712

Step-by-step explanation:
Technically, all 48 people came in red or blue cars, but I'm assuming that's not what the question is asking.
To find how many people came in blue cars, we do 2/3*48 which is equal to 32 people.
To find how many people came in red cars, we do 1/8*48 which is equal to 6 people.
