Answer:
(8, 2)
Step-by-step explanation:
Subtract the two D points.
(-12) - (-3) = -9
21 - 10 = 11
Then, use it to translate.
(17,-9)
(x - 9, y + 11)
= (8, 2)
The image of E(17,-9) under the translation will be (8,2)
Concept:The D and D' points are given First we will subtract D' from D and we will get X pointsTo find translation of of point E we will add X to E pointHow to solve this problem?The steps are as follow:
GivenD(-3,10)
D'(-12,21)
To find X we will subtract D' from DD'-D = (-12+3,21-10)
X(-9,11)
To find translation of E point we will add X points in EE' = (17-9,-9+11)
E' = (8,2)
Therefore the image of E(17,-9) under the translation will be (8,2)

Last year, Amy had $20000 to invest. She invested some of it in an account that paid 8% simple interest per year, and she invested the rest in an account that paid 9% simple interest per year. After one year, she received a total of $1690 in interest. How much did she invest in each account?
Answer:
Amount invested at 8% rate of interest = $11000
Amount invested at 9% rate of interest = $9000
Step-by-step explanation:
Let Amy invested amount in a account with 8% simple interest = $a
Then the interest gained after one year = [tex]\frac{\text{Principal amount}\times \text{Rate of interest}\times \text{Time}}{100}[/tex]
= [tex]\frac{a\times 8\times 1}{100}[/tex]
= 0.08a
Remaining amount for the investment = $(20000 - a)
Interest earned after one year with rate of interest 9%
= [tex]\frac{(20000-a)\times 9\times 1}{100}[/tex]
= $(1800 - 0.09a)
Total interest earned after 1 year = $1690
0.08a + (1800 - 0.09a) = 1690
1800 - 0.01a = 1690
0.01a = 110
a = $11000
Amount invested at 8% rate of interest = $11000
Amount invested at 9% rate of interest = $(20000 - 11000) = $9000

The soccer club has planned a trip to a tournament. The cost of the van is

transportation cost per person drops by $4.50. How many soccer club
members are going to the tournament?
A. 14
B. 11
C. -14
D. -14, 11
Answer: B: 11
Step-by-step explanation:
Just to the quiz for it
An equation is formed of two equal expressions. The number of players going to the tournament is 11.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Since the cost of the van is fixed, therefore, 231. Thus, the two equations can be written as,
P × x = 231(P-4.50)×(x+3)=231Solving the above two equations we will get,
Px + 3P - 4.50x -13.5 = 231
3P - 4.50x - 13.5 = 0
3P - 4.50x = 13.5
3(231/x) - (4.50x) = 13.5
693 - 4.50x² = 13.5x
-4.50x² - 13.5x + 693 = 0
x² + 3x - 154 = 0
x = -14, 11
Since the number of members can not be negative, the number of players going to the tournament is 11.

x = 125.44
Step-by-step explanation:
multiply each side of the equation by 7
17.92(7) = [tex]\frac{x}{7}[/tex](7)
125.44 = 7x / 7
7x / 7 = 1x or x

I will make you Brainliest. Pls answer fast I'm in a test.
Simplifying x + -12 = 36 Reorder the terms: -12 + x = 36 Solving -12 + x = 36 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '12' to each side of the equation. -12 + 12 + x = 36 + 12 Combine like terms: -12 + 12 = 0 0 + x = 36 + 12 x = 36 + 12 Combine like terms: 36 + 12 = 48 x = 48 Simplifying x = 48

There are 12 rolls of film in a box, and 4 are defective. Two rolls are to be selected, one after the other, sampling without replacement. What is the probability of selecting two defective rolls?
Group of answer choices
None of the answers is correct.
7/23
12/132
16/144
1/4
12/144
Using the hypergeometric distribution, it is found that the probability is 12/132
------------------------------------
The rolls are chosen from a sample without replacement, which means that the hypergeometric distribution is used to solve this question.
------------------------------------
Hypergeometric distribution:
The probability of x successes is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
------------------------------------
12 rolls means that [tex]N = 12[/tex]4 defective means that [tex]k = 4[/tex]2 are chosen, which means that [tex]n = 2[/tex]------------------------------------
What is the probability of selecting two defective rolls?
This is P(X = 2). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,12,2,4) = \frac{C_{4,2}*C_{8,0}}{C_{12,2}} = \frac{4 \times 3}{12 \times 11} = \frac{12}{132}[/tex]
12/132 is the probability.
