Answer:
[tex]W=9.41 pound[/tex]
Step-by-step explanation:
From the question we are told that:
Total amount spent [tex]n=\$=70[/tex]
Rate [tex]r= \$7.44\ per\ pound[/tex]
Generally the equation for Total pound of coffee W is mathematically given by
Total pound of coffee=Total amount spent/Rate
[tex]W=\frac{n}{r}[/tex]
[tex]W=\frac{70}{7.44}[/tex]
[tex]W=9.41 pound[/tex]

The function f(x) varies inversely with x and f(x)=0.5 when x = 0.3. What is f(x) when x = 2.4? A)5.76 B)0.0625 C)0.30 D)0.15
Answer:
B) 0.0625
Step-by-step explanation:
f(x) = k / x
f(x)=0.5 when x = 0.3
f(x) = k / x
0.5 = k / 0.3
Cross product
0.5 * 0.3 = k
k = 0.15
What is f(x) when x = 2.4?
f(x) = k / x
f(x) = 0.15 / 2.4
f(x) = 0.0625
The answer is B) 0.0625
Determine the period.
Answer:
the period is the to top points of the highest points on top of the crests
The period of function is,
P = 5
Since, In order to find the period of a graph in general, first, find the period of the parent function, and divide that by the absolute value of the coefficient of the independent variable.
Here, Graph of function is shown.
Hence, The period of function is,
P = 10/2
P = 5
Because there is two wave are shown.
Therefore, The period of function is,
P = 5

Answer: Hello your question is incomplete below is the complete question
In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport. in the same district, 19 of 67 randomly selected high school juniors play a varsity sport. a 95 percent confidence interval for the difference between the proportion of high school seniors who play a varsity sport in the school district and high school juniors who play a varsity sport in the school district is to be calculated. What is the standard error of the difference
answer : 0.0695
Step-by-step explanation:
First step : Determine the sample proportions
For P1 = 16 / 85 = 0.188
For P2 = 19 / 67 = 0.284
Next determine the Standard error of the difference using the relation below
Standard Error = [tex]\sqrt{\frac{p1(1 - p1)}{n1} + \frac{p2(1-p2)}{n2} }[/tex] ------- ( 1 )
where : P1 = 0.188

If a card is drawn at random from a standard 52-card deck, what is the probability that
the card drawn is:
Note: Give your answer as a fraction in simplest form or as a decimal rounded to the
nearest thousandths place.
a) a face card?
b) a red card?
c) a queen?
d) a club?
e) an Ace or 10?
Answer:
a) 12/52 = 3/14
b) 26/52 = 1/2
c) 4/52 = 1/13
d) 13/52 = 1/4
e) 8/52 = 2/13
Step-by-step explanation:
a) there are 12 face cards and 52 in the deck
b) half the cards are red, the other half black
c) one queen in each of four suits
d) the deck is broken up into 4 equal suits (hearts, diamonds, spades, clubs) so there are 13 of each.
e) like the answer in part C, there is one of each card in each of the four suits. that gives us four aces and four tens.

Part 1
Answer: (x+5)(x+10) - 50 = 126Other answers are possible.
-------------
Explanation:
The old width was 5, but then it increases to x+5. The old length was 10, but now it's x+10.
The area of any rectangle is length times width.
So the area of the larger rectangle is (x+5)(x+10). Subtract off the old area of 5*10 = 50 and we get (x+5)(x+10) - 50 as the area of the L shape. Set this equal to 126 to finish setting up the equation. This is one possible answer out of many others. This is because we could expand out the (x+5)(x+10) into x^2+10x+5x+50 or simplify that to x^2+15x+50, as two possible options.
==========================================================
Part 2
Answer: x = 6-------------
Explanation:
Solve the equation we set up in the previous part
(x+5)(x+10) - 50 = 126
x^2+10x+5x+50-50 = 126
x^2+15x = 126
x^2+15x-126 = 0
Apply the quadratic formula from here
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(15)\pm\sqrt{(15)^2-4(1)(-126)}}{2(1)}\\\\x = \frac{-15\pm\sqrt{729}}{2}\\\\x = \frac{-15\pm27}{2}\\\\x = \frac{-15+27}{2} \ \text{ or } \ x = \frac{-15-27}{2}\\\\x = \frac{12}{2} \ \text{ or } \ x = \frac{-42}{2}\\\\x = 6 \ \text{ or } \ x = -21\\\\[/tex]
Another method you could use is factoring, so you could say:
x^2+15x-126 = 0
(x-6)(x+21) = 0
x-6 = 0 or x+21 = 0
x = 6 or x = -21
The issue with this is that it may take a while to do this trial and error approach.
Whichever method you used, you'll end up with two solutions. One of those solutions doesn't make sense though. We can't have a negative length or distance value, so we ignore x = -21.
The only practical solution is x = 6
If x = 6, then the old height goes from 5 to x+5 = 6+5 = 11
If x = 6, then the old length goes from 10 to x+10 = 6+10 = 16
The new larger rectangle is 11*16 = 176 sq ft, in which we subtract off the 50 sq ft to get 176-50 = 126 sq ft, and this matches with the 126 given to us. Therefore, the answer is confirmed.

f(2) = 4 + 3
Then simplify.
f(2) = 7
Find the surface area of the composite figure.
Answer:
470
Step-by-step explanation:
there are several surface areas.
1. the 4 side walls of the big block = 4*12*7 = 336
2. top and bottom of the big block = 2* 7*7 = 98
3. subtract the small rectangular area from the top area covered by the small block = 2*7 = 14
4. the 3 (visible) side walls of the small block on top =
3* 2*7 = 42
5. the small top and bottom areas of the small block =
2* 2*2 = 8
so, 1.+2.-3.+4.+5. = 470

To evaluate g(7) substitute x = 7 into g(x) , that is
g(7) = [tex]\frac{7}{8}[/tex] × 7 - [tex]\frac{1}{2}[/tex]
= [tex]\frac{49}{8}[/tex] - [tex]\frac{4}{8}[/tex]

b. y=-4x-12
c. y=4x-12
d. y=-4x+12
Answer:
D igjdghhhgghgjgyigtyytttttrttuu
Answer:
C y = 4x - 12
Step-by-step explanation:
(1,-8) means x=1, y=-8
(4,4) means x=4, y=4
so, for which of the offered equations are both pairs right ?
a -8 = 4x1 + 12 = 16 wrong already for the first pair
b -8 = -4x1 - 12 = -16 wrong already for the first pair
c -8 = 4x1 - 12 = -8 hey, right !
4 = 4x4 - 12 = 16 - 12 = 4. hey, right
d -8 = -4x4 + 12 = -16 + 12 = -4. wrong already for the first pair
so, C describes an equation that covers both points. it is a linear function (no squares or so), and so it is a line function passing through both points.

Answer:
$120.29
