Maria invested her savings in two investment funds. The amount she invested in Fund A was $7000 less than the amount she invested in Fund B. Fund Areturned a 7% profit and Fund B returned a 3% profit. How much did she invest in Fund B, if the total profit from the two funds together was $1610?
It is given that,
The amount she invested in Fund A was $7000 less than the amount she invested in Fund B.
So, A=B-7000
And it is given that, Fund A returned a 7% profit and Fund B returned a 3% profit.
The total profit from the two funds together was $1610.
It can be written as,
7% of A +3% of B=1610
Substitute A=B-7000, we get
7% of (B-7000) +3% of B=1610
On solving we get,
[tex]\begin{gathered} \frac{7}{100}(B-7000)+\frac{3}{100}B=1610 \\ \frac{7}{100}B-490+\frac{3}{100}B=1610 \\ \frac{10}{100}B-490=1610 \\ \frac{1}{10}B=1610+490 \\ \frac{1}{10}B=2100 \\ B=21000 \end{gathered}[/tex]Hence, the investment in fund B is $21,000.

The parent function of the function g(x) = (x-h)² + k is f(x) = x2. The vertex of the function g(x) is located at (9,-8).
What are the values of h and k?
g(x) = (x-
².
Answer:
The values of h and k are 9 and -8, respectively
Step-by-step explanation:
This is how to determine the values of h and k
The vertex of the function g(x) is located at (9, –8)
The vertex of a function is represented as:
Vertex = (h,k)
This means that:
(h,k) = (9,-8)
By comparison, we have:
h = 9 and k = -8
So, the values of h and k are 9 and -8, respectively
Sam and Sophia participates in a dice game. Sophia rolls one die. She gets $2 if 5 turns up. She gets $3 if 6 turns up. She loses $10 if 2 turns up. She neither wins nor loses if any other face turns up. Is this game fair?The game is not fair and not favorable to player.The game is not fair, but favorable to player.The game is fair.The game is fair, but not favorable to player.
Hello there. To solve this question, we need to analyze the probabilities for each case and see if the game is fair or not and also favorable to the player.
Sophia rolls a dice. If 5 turns up, she gets $2; If 6 turns up, she gets $3; If 2 turns up, she loses $10; She neither wins nor loses if any other face turns up.
First, let's remember something that will be important: a dice only haves 6 faces.
As we can see, she is winning (getting money) if 2 out of 6 faces turns up (5 and 6), and is losing if 1 out of 6 faces turns up (2). She is neither winning or losing if 3 out of 6 faces turns up (1, 3, 4).
About the fairness of the game, there are only 1 case she loses and 2 cases she wins something. We could only say the game is fair if the amount of winning cases were equal to the amount of losing cases. The game is not fair.
About being favorable, we'll consider it being unfavorable just the case that she loses money. The first and third cases, in which she gets money or doesn't get or lose money are favorable to her.
Since only 1 out of 6 faces makes her lose, then the game is favorable to the player.
Final answer: The game is not fair, but favorable to the player.

Which word or phrase describes the probability that she reaches inwithout looking and pulls out an orange chew?impossiblelikelySubmit Answeran equal chance or 50-50O unlikely
Given that:
- There are 15 strawberry chews in the bag.
- There are 5 cherry chews in the bag.
You know that there is no orange chew in Kaylee's bag. Therefore, knowing this, you can determine that the probability that Kaylee reaches in without looking and pulls out an orange chew is:
[tex]P=0[/tex]By definition, the probability is zero when it is impossible for the events to happen.
Since there is no orange chew in her bag, it is impossible that she reaches in
without looking and pulls out an orange chew.

Upload the picture please,
First you need to find the slope using the formula
Slope = (y2 - y1) / (x2 - x1)
Choose two points from the table
P1 = (6, 38)
P2 = (5, 32)
Identify x1, y1, x2, y2
x1 = 6 y1 = 38 x2 = 5 y2 = 32
Substitute the values to find the slope
slope = m = (32 - 38) / (5 - 6)
= -6/-1
= 6
Find the equation of the line using the formula
y - y1 = m(x - x1)
x1 = 6 y1 = 38
Substitution
y - 38 = 6(x - 6)
Simplify
y - 38 = 6x - 36
Solve for y
y = 6x - 36 + 38
y = 6x + 2

Therefore, when daily output is 106300 units, the cost will be at its lowest.
Define costs.The average cost, or how much it generally costs to produce a unit, can be discovered using the cost function. The average cost function is defined as A(x)=C(x)x, where x > 0. The average cost per unit is calculated by dividing the total cost by the number of units produced. Costing is necessary to make sure that all costs are met and that the group decides on a price that will result in a profit. Finding ALL of a company's costs, including manufacturing, sales, administration, overhead, etc., is the first and most crucial stage. Costs are then divided into fixed and variable costs.
Given,
C=0.04x2 - 8.504x + 25302....... (1), where x is the number of units produced in thousands, gives the cost of generating x thousands of units of lemon-scented widgets in a day.
We must determine the daily production rate that will reduce costs.
dC/dx = 0
The current prerequisite for minimum cost is
0.08x - 8.504 = 0
0.08x = 8.504
x = 106.3
In light of equation (1),
x =106.3

Answer
The answer = 5,184,000,000
There are 5,184,000,000 possible phone numbers.
Explanation
The question told us that telephone numbers are in the form NYZ-ABC-XXXX, then proceeds to give us the restrictions on some of the positions available.
- N can only be numbers: 2-9;
- Y can only be numbers 0-7
- and A&C cannot be 2
We are then told to calculate the number of phone numbers possible.
This question is a special type of permutation and combination.
To solve it, it will be a multiplication of the possible numbers that can take up each position.
N, can only be numbers 2 to 9. Number of possible digits = 8
Y, can only be numbers 0 to 7. Number of possible digits = 8
Z, no restriction, can have numbers 0 to 9. Number of possible digits = 10
A, number cannot be 2. Number of possible digits = 9
B, no restriction, can have numbers 0 to 9. Number of possible digits = 10
C, number cannot be 2. Number of possible digits = 9
X, no restriction, can have numbers 0 to 9. Number of possible digits = 10
X, no restriction, can have numbers 0 to 9. Number of possible digits = 10
X, no restriction, can have numbers 0 to 9. Number of possible digits = 10
X, no restriction, can have numbers 0 to 9. Number of possible digits = 10
Total number of possible phone numbers

Original price of a camera: $799.95Discount: 17%What's the selling price
Answer:
$663.95
Explanation:
Given the following:
Original price of a camera: $799.95
Discount: 17%
Discounted price = 17% of original price of the camera
Discounted price = 0.17*$799.95
Discounted price = $135.99
Selling price = Original Price - Discounted price
Selling Price = $799.95 - $135.99
Selling price = $663.96
Hence the selling price is $663.95

let s1 and s2 be the distance covered by the two buses
s1 + s2 = 350 ................................eqn I
velocity (v) = distance (s)/time (t) .........................eqn II
from eqn II the velocity of the first bus, v1 = s1/t1
s1 = v1t1 .................................eqn III
velocity of the second bus, v2 = s2/t2
s2 = v2t2 ...........................eqn IV
substitute eqn III and eqn IV into eqn I
v1t1 + v2t2 = 350
the time taken for any two moving objects to simultaneously cover any distance is equal. Thus,
t1 = t2 = t
eqn V becomes
v1t + v2t = 350
t(v1 + v2) = 350
v1 = 40
v2 = 60
t(40 + 60) = 350
100t = 350
divide both sides by 100
100t/100 = 350/100
t = 3.5 hours
