7h-5(3h-8)=-72
Answer:
h=14
Step-by-step explanation:
7h-5(3h-8)=-72
Combine Like Terms
-8h+40=-72
Subtract 40 on both sides
-8h+40 -40 = -72 -40
Then we get
-8h/8=-112/8 so we divide by 8
h=14
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

g 5. (Sec. 5.1) Suppose the marginal pdfs of two independent rvs X and Y are given byfX(x) = (5x4 for 0 x 10 otherwisefY (y) = (2y3 + y for 0 y 10 otherwise(a) Find the joint pdf of X and Y .
Answer:
f(x,y) = 5x⁴(2y³ +y ) 0<x<1 , 0<y<1 , 0 otherwise
Step-by-step explanation:
Given
F(x) = 5x⁴ for 0<x<1 and 0 otherwise
f(y)= 2y³ +y for 0<y<1 and 0 otherwise
the joint p.d.f is given by
f(x,y) = f(x) * f(y)= 5x⁴(2y³ +y ) 0<x<1 , 0<y<1 , 0 otherwise
The joint pdf is found by multiplying the marginal pdfs.
The two random variables are said to be statistically independent if the joint probability function can be expressed as the product of two marginal functions.
Shares in stock of a new company are selling for $3.75 per share. An investor has $800. Which inequality can be solved to show the number of shares s he can buy?
Given:
Price of each share = $3.75
Total amount invertor has = $800
To find:
The inequality that can be solved to show the number of shares s he can buy.
Solution:
Let x be the number of shares he can buy.
Price of 1 share = $3.75
Price of x shares = $3.75x
An investor has $800.
The price of x shares must be less than or equal to the amount he has. So,
[tex]3.75x\leq 800[/tex]
Divide both sides by 3.75.
[tex]x\leq \dfrac{800}{3.75}[/tex]
[tex]x\leq 213.33...[/tex]
So, the maximum possible integer value of x is 213.
Therefore, the equation inequality is [tex]3.75x\leq 800[/tex] and he can buy 213 shares.
What is an equation of the line that passes through the point ( 1 , 7 ) and is parallel to the line
3x−y=1?
Answer:
(y-1)= 3(x-7)
Step-by-step explanation:
1. you put the equation given in slope intercept form so y=3x-1.
2. you find the slope, parellel lines have the same slope so the slope for the new equation will remain 3.
3. then you write the point-slope form equation
4) make sure to plug in the x1 and y1 values from the coordniates given
The required equation of the line is given as 3x - y = -4.
Given that,
The equation of the line that passes through the point ( 1, 7 ) and is parallel to the line 3x−y = 1 is to be determined.
The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx where x in degrees.
here,
The standard equation of the line is given as,
y = mx + c,
Since the line is parallel to line 3x - y = 1 whose slope is m = 3, and also the slope of the parallel line are equal.
so,
y = 3x + c
Put points (1, 7) in the above equation,
7 = 3 + c
c = 4
y = 3x + 4
Thus, the required equation of the line is given as 3x - y = -4.

Which of the following ordered pairs is represented by a point located on the y-axis?
Select one:
a.(6,-6)
b. (3,3)
c. (0,8)
d. (-5,0)
Answer:
d (-5,0)
Step-by-step explanation:
If a point is located on the x-axis, then the y-coordinate is 0.
d is the only point that sits on the x-axis. I know this because it's y-coordinate is 0.
(0,8) is actually a point sitting on the y-axis.

if 2/3 of the girls in class have brown eye and 1/4 of the girls have blue eyes what fraction of the girls in class have neither blue or brown eyes
Answer:
1/12 have neither blue or brown eyes.
Step-by-step explanation:
First you change the fractions to have an equal denominators. 2/3= 8/12. 1/4= 3/12.
Then you add them
8/12 + 3/12= 11/12
After that you subtract 12/12- 11-12= 1/12

An astronaut is returning to Earth in a spacecraft. If the spacecraft is descending at a rate of 13.81 kilometers per minute, what will its change in height after 5 1/2 minutes?
Answer: -75.955
Step-by-step explanation:
the astronaut is descending 13.81km each minute, so multiply that by 5 and a half minutes you get 75.955. Since he is going down, his height will change by a negative 75.955 instead of a positive one.

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!

m√3/3 - ³11 = ³4
m√3 - 33 = 12
m√3 = 12 + 33

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
