Answer:
X=32 and Y=51
Step-by-step explanation:
first to find the answer, we must establish that the sum of 3 angles in any triangle will equal 180 degrees, and both triangles are congruent then we can start making equations. Triangle STU has 2 numbers and one equation on it, the equation for the length of NP will give us y, but first we must get X from the equation for angle TUS which is congruent to angle MNP, so first we must add angle M and angle P together to find angle N, 142+24=166, 180-166=14, so angle N and angle U are both equal to 14 degrees, so, 2x-50=14 first add 50 to both sides then divide by 2 giving us 32=X. Now that we have x, we can find y, 2x32-y=13, we can determine m is equal to 13 m because segment SU is congruent to segment NP, SU is 13 meters, thus NP is 13 meters long as well. first multiply 32 and 2 giving 64, then subtract 64 from both sides, giving you -y=-51, but we don't stop here because y itself can't be negative as that's not what's being asked for, so divide both sides by negative 1 giving you Y=51

The plans for constructing a raised vegetable garden use corrugated
metal in a wooden frame. The finished garden is 4 feet long, 30 inches wide, and
32 inches tall.
The metal is only used on the lateral faces, so how many square feet of metal
should be purchased? Round to the nearest square foot
Answer:
35 square feet of metal should be purchased
Step-by-step explanation:
The rule of the lateral area is L.A = perimeter of the base × height1 foot = 12 inchesLet us use the fact above to solve the question
∵ The garden is 4 feet long
∵ Its wide is 30 inches
→ Change it to feet by divide it by 12
∴ Its wide = 30 ÷ 12
∴ Its wide = 2.5 feet
∵ It is 32 inches tall
→ Change it to feet by divide it by 12
∴ Its tall = 32 ÷ 12
∴ Its tall = 8/3 feet
∵ The perimeter of the rectangle = 2(length + width)
∵ Length = 4 feet and wedth = 2.5 feet
∴ The perimeter of the base = 2(4 + 2.5)
∴ The perimeter of the base = 13 feet
→ Substitute it in the rule above
∴ L.A = 13 × h
∵ The height = 8/3 feet
∴ L.A = 13 × 8/3
∴ L.A = 34.666667 feet²
→ Round it to the nearest square foot
∴ L.A = 35 feet²
∴ 35 square feet of metal should be purchased
Let f (x comma y )equals 4 x squared minus 9 x y plus 6 y cubed. Find f subscript x (x comma y ).
Answer:
Fx(x,y) = 8x -9y
Step-by-step explanation:
Given f(x,y) = 4x²-9xy+6y³, we are to find the derivative of the function with respect to x keeping y as constant.
Fx(x,y)
This is known as partial derivative of the function.
Fx(x,y) = 2(4)x^(2-1) - 9y + 0
Fx(x,y) = 8x -9y
Note that the differential of a constant is zero, hence the reason why 6y³ tends to zero since there are no x variable attached.

One of the two points Seamus used to determine the slope of his trendline was (0.00286,4.27). If the slope of his trendline is 8,749 K, what is the y-intercept of his trendline
Answer:
c = -25017.87
Step-by-step explanation:
The slope of his trendline is 8,749 K
The two points that are used to find the slope of his trendline was (0.00286,4.27).
We need to find the y-intercept of his trendline. Slope of equation is given by :
y = mx +c
We need to find c.
Put y = 4.27, m = 8,749000 and x = 0.00286
c = y-mx
c = 4.27- 8,749000 (0.00286)
c = -25017.87
So, the y -intercept of his trendline is 25017.87
The mass of a hummingbird is
4,000 milligrams. Use a
proportion to convert 4,000
milligrams to grams
PLEASE HELPPPPP
Answer:
4 grams
Step-by-step explanation:
There are 1000 milligrams in a gram, so the proportion is 1g/1000mg=xg/4000mg
when you cross multiply, you get 1000xg=4000mg/ divide both sides by 1000 and you get xg=4, meaning x=4 grams
Mike owes his friend $4. Each day, Mike earns $2.
(1) Write an equation that describes the situation in slope-intercept form and explain what the x- and y-values represent.
(2) Graph the situation on a coordinate plane assuming the domain is all real numbers.
(3) What does the x-intercept mean? What does the y-intercept mean?
(4) Does the situation involve direct variation or not? If it does, justify your answer. If it does not, describe how the situation would need to change in order for y to directly vary with x. Then, write a direct variation equation based upon the changed situation.
Answer && Step-by-step explanation:
We know that an equation can be used, 2*x=4
slope int form : y=mx+b
b is not necessary here
1. 4=2x
2 represents the amount of dollars, x represents amount of days, y represents the required result
2. make y, 0: 2x=0
plug in values for x to represent y values
3. x means how much money he has and y is how many days
(x,y)
4. It does involve direct variation. y/x == k
4/2=2 which is exactly what we need to get 4
Answer:
1)
[tex]y=2x-4[/tex]
2)
Please see below for the graphs.
3)
The x-intercept means that Mike will pay off his debt after 2 days.
The y-intercept means that Mike initially owes his friend $4.
4)
No, it does not involve direct variation.
We can change it to direct variation if we remove the debt Mike owes.
The direct variation equation will then be:
[tex]y=2x[/tex]
Step-by-step explanation:
We know that Mike owes his friend $4. Each day, Mike earns $2.
Part 1)
Let y represent the amount of money Mike will have after x days.
Since Mike owes his friend $4, this means that the original amount he has is -4.
However, Mike earns $2 per day. So, our slope will be +2x.
Putting this all together, the equation that represents Mike’s situation is:
[tex]y=2x-4[/tex]
The y represents Mike’s total assets (money). The -4 represents what Mike started with, he $4 he owes. And the 2x represents the amount Mike will have after x days since he earns $2 per day.
Part 2)
Please see the graph below.
To graph by hand, first start by drawing a dot at the y-intercept, (0, -4).
Now, since our slope is 2, this is the same as saying 2/1.
So, draw a dot by going up 2 for every 1 right. Do this at least twice. This should yield three dots.
Finally, connect them with a graph.
I’ve also done it by hand to give you a visual.
Part 3)
So, from the graph, we can see that the x-intercept is (2, 0).
And the y-intercept is (0, -4).
The x-intercept tells us that when x is 2, y is 0.
Therefore, this means that after two days, Mike would’ve paid off his debt of $4.
Similarly, our y-intercept tells us that when x is 0, y is -4.
So, on Day 0, when Mike haven’t earned any money yet, he owes $4 as illustrated by -4.
Part 4)
Remember that direct variation equations must always go through the origin point.
Since our equation does not go through the origin, our equation is not direct variation.
Remember that for a graph to be direct variation, the y-intercept must be 0.
In other words, if Mike doesn’t owe any money at the start, we will have direct variation.
Thus, if the situation changed such that Mike doesn’t owe his friend any money, then we will have a direct variation equation.
Since he doesn’t owe any money, our y-intercept is 0. He will still earn $2 per day. Therefore, our equation will be:
[tex]y=2x[/tex]
Here, our constant of variation is 2, illustrating that Mike earns $2 per day.
And we are done!
A normal die (numbered 1-6) is fair if each outcome is equally likely. Therefore a 1 should come up of the time. If a fair die is rolled 360 times we would expect a 1 to come up 60 times (since 1 over 6 times 360 equals 60 ). If x represents the number of times a "1" is rolled then open vertical bar fraction numerator x minus 60 over denominator square root of 50 end fraction close vertical bar less than 1.96 gives the reasonable range for the number of times a "1" will come up in 360 rolls. If we roll the die 360 times and get a "1" 30 times, is our die a fair die? Show your work using the equation editor.
Answer:
Yes the die is fair as the calculated z= -0.224 is less than the Z∝= 1.96
Step-by-step explanation:
x`- u / s/√n< Z∝
x`- 60 /√50/√360 < 1.96
From the above we find that u = 60 and the sample size n= 360 S= √ 50
Z∝= 1.96
Here p = 1/6 ( the probability of getting a 1 out of 6)
q= 5/6
Since it is normal Standard deviation = √npq = √360 * 1/6*5/6= √50
If x`= 30
then
30 - 60 /√50/√360 < 1.96
-30/7.07*18.973 < 1.96
- 0.224 < 1.96
Yes the die is fair as the calculated z= -0.224 is less than the Z∝= 1.96 the null hypothesis that die rolled is fair is accepted.

A farmer's market sells pecans, walnuts, and cashews. They each have a
different cost and are priced per pound. Alyssa buys three pounds of walnuts
and four pounds of cashews and spends $32. Landon buys seven pounds of
pecans and five pounds of walnuts and spends $65. Tina buys 3 pounds of
pecans and 2 pounds of cashews and spends $22. Find the missing quantity
below.
D
Price per pound for Pecans = $
Answer:
Price per pound for Pecans = $5
Step-by-step explanation:
Let price per pound of walnut be x, price per pound of pecans be y and price per pound of cashew be z.
Thus;
For alyssa;
3x + 4z = 32 - - - (eq 1)
For Landon:
5x + 7y = 65 - - - (eq 2)
For Tina;
3y + 2z = 22 - - -(eq 3)
From eq 3, let's make z the subject;
z = (22 - 3y)/2
Putting this for z in eq 1 gives;
3x + 4((22 - 3y)/2) = 32
3x + 2(22 - 3y) = 32
3x + 44 - 6y = 32
3x - 6y = -12
Divide through by 3 to get;
x - 2y = -4 - - - eq(4)
Multiply through by -5 to give;
-5x + 10y = 20
Add this to eq 2 to get:
5x - 5x + 7y + 10y = 65 + 20
17y = 85
y = 85/17
y = 5
Thus, Price per pound for Pecans = $5

The defect rate for your product has historically been about 1.00%. For a sample size of 400, the upper and lower 3-sigma control chart limits are: UCLp =
Answer: Lower limit = -0.05 and Upper limit = 0.025
Step-by-step explanation:
3-sigma , p chart control limits:
Lower limit = [tex]p-3\sqrt{\dfrac{p(1-p)}{n}}[/tex]
Upper limit = [tex]p+3\sqrt{\dfrac{p(1-p)}{n}}[/tex] , where n= sample size .
Given: p= 0.01 , n= 400
Lower limit = [tex]0.01-3\sqrt{\dfrac{0.01(1-0.01)}{400}}[/tex]
[tex]=0.01-3\sqrt{0.00002475}\\\\= 0.01-3(0.005)=-0.05[/tex]
Upper limit= [tex]0.01+3\sqrt{\dfrac{0.01(1-0.01)}{400}}[/tex]
[tex]=0.01+3\sqrt{0.00002475}\\\\= 0.01+3(0.005)=0.025[/tex]
hence, Lower limit = -0.05 and Upper limit = 0.025
