Answer:
There is loss of 10%
Step-by-step explanation:
The total sum of money invested [tex]= 13000[/tex] dollars
In the first year, the Investment values decreases by 40%. The final investment value after one year
[tex]\frac{(100-40)}{100} * 13000\\7800[/tex]
Now in the second year the investment increases by 50%. The final investment value after second year
[tex]\frac{100+50}{100} *7800\\1.5 * 7800\\11700[/tex]
The investment value after second year is less than that of total sum invested
% loss
[tex]\frac{13000-11700}{13000} * 100\\10[/tex]percent
There is loss of 10%
Help plz, these questions are very confusing :/
Answer:
1.
cos ∅=b/h=24/25
:.b=24
h=25
by using Pythagoras law
h²=p²+b²
25²=p²+24²
p²=25²-24²
p=√7²=7
now
sin ∅=P/h=7/25
tan∅=p/b=7/24
2.cos ∅ is your answer
sec∅-sin∅tan∅
1/cos∅-sin²/cos∅
(1-sin²∅)/cos∅
cos²∅/cos∅
cos∅
3.
tan²∅-sec²x

Answer:
y=2x+3 C
Step-by-step explanation:
The first point (0,3) tells us the y intercept of 3 and we can use the slope formula to figure out that the slope is 2.
Divide the rational expressions
(X/x+1)(2/x)
( 1 + 1 )( 2/x )
(2)(2/x)
4/x

order the numbers 0.3, 2/5, -0.85, 0.09, 3/4, 3/20 least to greatest
Answer:
-0.85, 0.09, 3/20, 0.3, 2/5, 3/4
Step-by-step explanation:
Turn all the fractions into decimals
2/5 -> .4
3/4 -> .75
3/20 -> .15
Then order them
-.85, 0.09, 0.15, 0.3, 0.4, 0.75
Two college instructors are interested in whether or not there is any variation in the way they grade math exams. They each grade the same set of 10 exams. The first instructor's grades have a variance of 58.9. The second instructor's grades have a variance of 84.8. Test the claim that the first instructor's variance is smaller. (In most colleges, it is desirable for the variances of exam grades to be nearly the same among instructors.) The level of significance is 10%. (Recall: that the larger of the 2 variances needs to be in the numerator as the test is 1-tailed to the right)
Answer:
Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Step-by-step explanation:
1)Formulate the hypothesis that first variance is equal or greater than the second variance
H0: σ₁²≥σ₂² against the claim that the first instructor's variance is smaller
Ha: σ₁²< σ₂²
2) Test Statistic F= s₂²/s₁²
F= 84.8/ 58.9= 1.4397
3)Degrees of Freedom = n1-1= 10-1= 9 and n2 = 10-1= 9
4)Critical value at 10 % significance level= F(9,9)= 2.4403
5)Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.

Find an equation for the line below?
Please help I’m not very good with figuring out graphing
Answer:
y = 1/3x + 8/3
Step-by-step explanation:
To find an equation use two points to gather the slope and y-intercept.
(1, 3) (-5, 1)
Slope:
y2 - y1 / x2 - x1
1 - 3 / -5 - 1 = -2 / -6
-2 / -6 = 1 /3
y = 1/3x
y intercept is 8/3
Equation: y = 1/3x + 8/3

What is the area of the square? A square with the left side labeled 4 units.
Answer:
Area = 16 units
Step-by-step explanation:
Area = length * width Length = x Width = w
A = (x) (w)
Because the shape is a square we know all 4 sides are equal, the lenth and width are the same sizes.
x = 4 units
w = 4 units
A = 4*4
A= 16 units
Which equation demonstrates the multiplicative identity property?
(-3+5i)+0=-3+5i
(-3+5i)(1)=-3+5i
(-3+5i)(-3+5i)=-16-30i
(-3+5i)(3-5i)= 16+30i
Answer:
(-3+5i)(1)=-3+5i
Step-by-step explanation:
The multiplicative identity is given by :
[tex]a\times 1=a[/tex]
Where
a can be any number
Out of 4 options, in option (2), (-3+5i) is multiplied by 1 and after multiplying we get (-3+5i).
Hence, the correct option is (b).

Tim says 1/8 of this model is shaded. Lucy says 8/8 of this model is shaded.
Answer:
Step-by-step explanation: Lucy is correct because all of the squares are filled, and therefore instead of 1 square filled, 8 are, this is why lucy is correct :)
Answer:
Lucy is correct.
Step-by-step explanation:
We can see that the ENTIRE model is shaded ( all eight squares).
So Lucy is correct since she stated that 8 out of 8 (8/8) squares are shaded.
8/8 = 1, so whole.
1/8 would mean that only one out of eight squares is shaded, so Tim is NOT coorrect.

A play has two different male roles, two different female roles and two different roles that can be either gender. Only a man can be assigned to a male role, and only a woman can be assigned to a female role. If five men and six women audition, in how many ways can the six roles be assigned?
There are total 66,000 ways the six roles can be assigned.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Since only a man can play a male role,
We have 5 options for the first male role and 4 options for the second male position (because a guy cannot play both roles).
So there are 5x4 = 20 options for male roles.
Next, consider how many different ways the female positions can be filled. Because only a woman can play a female role,
We have six options for the first female role and five options for the second female position (because a woman cannot play both roles).
So there are 6x5 = 30 possibilities for female roles.
Finally, consider how many different ways the gender-neutral roles can be filled. Because any of the 11 actors can play these parts,
We have 11 options for the first gender-neutral role and 10 options for the second (because one actor cannot play both roles).
So there are 11x10 = 110 possibilities for gender-neutral jobs.
To find the total number of ways the six roles can be assigned,
we multiply the number of ways to fill each set of roles,
Hence,
20 x 30 x 110 = 66,000.

Suppose that you are attempting to buy a house, and you are bargaining with the current owner over the sale price. The house is of value $200,000 to you and $100,000 to the current owner; so, if the price is between $100,000 and $200,000, then you would both be better off with the sale. Assume that bargaining takes place with alternating offers and that each stage of bargaining (an offer and a response) takes a full day to complete. If agreement is not reached after seven days of bargaining, then the opportunity for the sale disappears (you will have no house and the current owner has to keep the house forever). Suppose that you discount the future according to the discount factor 0.3 per day and the current owner discount the future at discount factor of 0.6 per day. The real estate agent has allowed you to decide whether you will make the first offer. Should you make the first offer or let the current owner make the first offer? Why? Suppose that you have to make the first offer, what will be your offer that is going to be acceptable to the current owner?
Answer:
the answer is to make the first offer!
Step-by-step explanation:
Since the surplus ($100000) is rapidly depleting, and though the second individual collects the whole surplus, it is already less than half of the surplus from the previous day. So, once you make the first bid, any offer above 100,000 would be fair to the second person and if he rejects the offer, he will only be able to get 100,000 the next day. You will raise the payout by 100000(1 ) this way.
