Answer:
In this problem, given the focus at (2,4) and directrix at y = 8. then it is implied that the parabola is facing downwards. The vertex hence is at the middle of the focus and the directrix, hence at (2, 6). The general formula of the parabola is y-k = -4a ( x-h)^2. Substituting, y -6 = -1/8 *(x-2)^2. Answer is A.

Benjamin has 10 marbles in a bag. 4 are red, 2 are blue, 3 are green, and 1 is yellow.
Part A: What is the probability of drawing a color other than blue?
Part B: You draw two marbles with replacement. What is the probability of drawing a red, then a blue?
Part C: What is the probability that you draw a yellow and then draw a red without replacement?
Answer:
A) 4/5
B) 2/25
C) 2/45
Step-by-step explanation:
A) P(not blue) = 8/10 or 4/5
B) P(red,blue) = 4/10 x 2/10 = 2/25
C) P(yellow,red) = 1/10 x 4/9 = 2/45

8x + 7 = 6x + 15
what is x
Answer:
x = 4
Step-by-step explanation:
i am smart
Answer:
X=4
Step-by-step explanation:
Simplifying
8x + 7 = 6x + 15
Reorder the terms:
7 + 8x = 6x + 15
Reorder the terms:
7 + 8x = 15 + 6x
Solving
7 + 8x = 15 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
7 + 8x + -6x = 15 + 6x + -6x
Combine like terms: 8x + -6x = 2x
7 + 2x = 15 + 6x + -6x
Combine like terms: 6x + -6x = 0
7 + 2x = 15 + 0
7 + 2x = 15
Add '-7' to each side of the equation.
7 + -7 + 2x = 15 + -7
Combine like terms: 7 + -7 = 0
0 + 2x = 15 + -7
2x = 15 + -7
Combine like terms: 15 + -7 = 8
2x = 8
Divide each side by '2'.
x = 4
Simplifying. Hope this helps :D

Point 4,6 is reflected across line y= X and then dilated by a factor of 1/2 using the origin as the center of dilation. What is the resultant point?
9514 1404 393
Answer:
(3, 2)
Step-by-step explanation:
Reflection across y=x swaps the coordinates:
(x, y) ⇒ (y, x)
Dilation by a factor of 1/2 multiplies each coordinate by 1/2.
(x, y) ⇒ (x/2, y/2)
The combination of these transformations gives you ...
(x, y) ⇒ (y/2, x/2)
(4, 6) ⇒ (3, 2)

The manufacturer of running shoes conducted a study on its newly developed jogging shoe. Listed are the type and frequency of the nonconformities and failures found. A Pareto chart to show the major problem areas is given below. (Round your answers to 1 decimal place.) Type of Nonconformity Frequency Type of Nonconformity Frequency Sole separation 36 Lace breakage 13 Heel separation 92 Eyelet failure 8 Sole penetration 60 Other 16
Answer: Hi your question is poorly structured I believe your question is construct a pareto chart to show the major problem areas
answer : attached below is the pareto chart.
Step-by-step explanation:
Rearranged table starting from highest frequency
The type of Nonconformity Frequency Percentage
Heel separation 92 40.89
sole penetration 60 26.67
Sole separation 36 16
Other 16 7.11
Lace breakage 13 5.8
Eyelet failure 8 3.5
Total = 36 + 13 + 92 + 8 + 60 + 16 = 225
Next step : determine the percentages of the various Nonconformity
sole separation = 36 / 225 ) * 100 = 16%
lace breakage = ( 13/225 ) * 100 = 5.8% = 6%
Heel separation = ( 92/225 ) * 100 = 40.89% = 41%
Eyelet Failure = ( 8 /225 ) * 100 = 3.5% = 4%
sole penetration = ( 60 / 225 ) * 100 = 26.67% = 27%
other = ( 16 / 225 ) * 100 = 7.11% = 7%

To make 1000 containers of ice cream you need: 600 units of milk, 275 units of cream, and 120 units of flavor. Each ingredient is contained in tanks like the ones pictured below. Note the capacity of each container. Adjustments to one ingredient must be followed by corresponding adjustments to the other ingredients. If the pump on the milk tank pumps milk out at a rate of 50 units per minute, how long would it take to empty the 1000 unit milk tank
Answer:
It will take 20 minutes to pump out 1000 unit milk tank
Step-by-step explanation:
The pump on the milk tank pumps milk out at a rate of 50 units per minute,
1 minute = 50 units
x minutes = 1000 units
Using the unitary method x= = 1000*1/50= 20 minutes
It will take 20 minutes to pump out 1000 unit milk tank
Question #1
Correct answer is E,

Unfortunately, doing this kind of problem by hand would take a very long time. So I recommend using a graphing calculator. Specifically, one that can handle numeric integration. You'll need to find the area under the curve from t = 0 to t = 3. This will tell you the change in velocity during the time period from t = 0 to t = 3 seconds. You should find that
[tex]\displaystyle \int_{0}^{3}\frac{t+3}{\sqrt{t^3+1}}dt \approx 6.71005[/tex]
If you want to do this by hand, you can use Riemann rectangles to break up the area and find the area of each rectangle. Though use of a calculator is recommended here as well.
This result will add onto the initial velocity of 5 to get a final approximate result of 5+6.71005 = 11.71005 which rounds to 11.710
A bookshelf costs $300 normally. Today it is on sale and decreased by 20% However there is
also a 4% sales tax. What is the new cost of the bookshelf?
Answer:
249.60
Step-by-step explanation:
300 x .8 (100%-20%)=240
240 x .04 (4% sales tax)=9.60
price = 240+9.60=249.60

Answer:
10.5, 31.5, and 6.
Step-by-step explanation:
So to find the answers here, we must find the value of t, when h equals 1.
To do this, lets take a h-t value we already know, and solve.
We can use: when h=2 t equasl 21:
2h=21t
So if we divide both sides by two we get:
2h/2=21t/2
=
h=10.5t
So know we know for every one h, t is 10.5
This can be verifyed with 4h = 42t. Which after solving, equals 1h=10.5t
So now that we have a value for t, lets get our solutions.
First off, we have 1h=__t?
Well, we have already made this one clear. It would be 10.5t, since for every 1h we have 10.5t
Next up, we have 3h=___t
All we have to do it multiply 10.5 by 3 to solve this:
10.5*3
=
31.5
So this is our second fill in answer.
Finally we have ___h=63t
We must divide both sides by 10.5, which is equal to 1t, to find this answer:
63/10.5
=
6
So our last fill in answer is 6.
Hope this helps!

How do you graph y = 2/3x + 1

Step-by-step explanation:
Easy way: use a graphing calculator.

Manually: plot the y-intercept and another point.
The given equation is in slope-intercept form:
y = mx + b . . . . . . . slope m, y-intercept b
For this line, the slope is 2/3, and the y-intercept is 1.
This means the line crosses the y-axis at y=1. You can plot that point on your graph.
The slope of 2/3 means the line will rise 2 units for each 3 units to the right. 3 units right of the y-axis is x=3. 2 units up from y=1 is y=3. So, another point on the line is (x, y) = (3, 3). Plot that point and draw a line through the points you have identified.
