Answer:
Rick Arico invested $4100 at a yearly rate of 7% and $900 at a yearly rate of 9%.
Step-by-step explanation:
Let x represent the amount invested at 7% yearly rate and let y represent the amount invested at 9%.
$5000 was split and invested at 7% yearly rate and 9% yeatly rate. Therefore:
x + y = 5000 (1)
For the 7% yearly rate:
Interest = (x * 7%) = 0.07x
For the 9% yearly rate:
Interest = (y * 9%) = 0.09y
The total interest = interest for the 7% yearly rate + Interest for the 7% yearly rate = 0.07x + 0.09y
Given that the total interest earned in the year was $368, hence:
0.07x + 0.09y = 368 (2)
To find x and y, we have to solve equation 1 and equation 2 simultaneously. multiply equation 1 by 0.07 and subtract the result from equation 2 to get:
0.02y = 18
y = 18 / 0.02
y = $900
Substitute y = $900 in equation 2:
0.07x + 0.09(900) = 368
0.07x + 81 = 368
0.07x = 287
x = $4100
Therefore Rick Arico invested $4100 at a yearly rate of 7% and $900 at a yearly rate of 9%.

Mae Ling earns a weekly salary of $325 plus a 7.5% commission
on sales at a gift shop. How much would she make in a work week if she sold
$5,800 worth of merchandise? Write in money format.
Answer:
$760
Step-by-step explanation:
Given data
weekly = $325
commission= 7.5%
if she sold $5,800 worth of merchandise
Her earnings will be
Week earning= base salary+ 7.5% of sales
Week earning= 325+ 7.5/100*5800
Week earning= 325+ 0.075*5800
Week earning= 325+ 435
Week earning= $760
If 40 chairs are bought for Rs
10000 then how many
chairs must be
Sold
for
10000
gain 60%?
Answer:
25 chairs
Step-by-step explanation:
If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?
The percent gain = 60%
Number of chairs to be sold = x
Hence:
40 chairs = 10,000
60/100= 40 - x/x × 100
0.6= 40 - x/x
Cross Multiply
0.6x = 40 - x
0.6x + x = 40
1.6x = 40
x = 40/1.6
x = 25 chairs

Answer:y’all it’s all of them ABE
Step-by-step explanation:
The statements that are correct are:
B) The model predicts that studying for 1.5 hours will result in an exam score of 60.
C) The model predicts that studying for 2.5 hours will result in an exam score of 70.
A scatter plot is a collection of points plotted on two axes, horizontal and vertical. Scatter plots are useful in statistics because they illustrate the extent, if any, of correlation between the values of observed quantities or phenomena (called variables).
The scatter plot shows a positive relationship between study time and exam scores, with exam scores generally increasing as study time increases. However, the relationship is not linear and the increase in exam score is not always 10 points for each additional hour of study.
A) is not correct because the relationship between study time and exam score is not linear, and the increase in exam score is not always 10 points for each additional hour of study.
D) is not correct because the wording is unclear, it should be "The model predicts that studying for 4 hours will result in an exam score of (a specific number)".

Answer:
[tex]x = 13[/tex]
Step-by-step explanation:
Given

Find x
From the attachment, we have:
[tex]BC = x + 4[/tex]
[tex]BD = 2x - 7[/tex]
[tex]GE = 51[/tex]
[tex]GF = 57[/tex]
Because both triangles are similar, we use the following equivalent ratios:
[tex]BC : BD = GE : GF[/tex]
Substitute values for each parameter
[tex]x + 4 : 2x- 7 = 51 : 57[/tex]
Convert to fractions
[tex]\frac{x + 4}{2x- 7} = \frac{51 }{ 57}[/tex]
Simplify the right-hand side
[tex]\frac{x + 4}{2x- 7} = \frac{17}{19}[/tex]

Answer: No, it is not commutative. If used a square as an example, centered at (1,1). If a dilation is performed on the square of a scale factor of 3, and the square is translated 5 units downward, then the result would be different than if I switched the order, doing the translation downward first and then performing the dilation centered at (1,1).

Which graph represents (x,y)-pairs that make the equation y=0.5+5 true?
Choice B: (1,0), (3,4), (6,10)
Choice C: (2,6), (4,7), (6,8)
Answer:
Choice C
Step-by-step explanation:
Notice that the equation y = 0.5 x + 5
is a linear equation so the points that are solutions of it must reside on a line. Option A does not show aligned points, so it cannot be a possible answer.
Option B: we look into the given points and notice that just the first one (1, 0) is NOT a solution to the equation because:
y = 0.5 (1) + 5 = 5.5 and not "0"
Option C: This is the correct answer, since all those points satisfy the equation
Point (2, 6) --> y = 0.5 (2) + 5 = 1 + 5 = 6
Point (4, 7) --> y = 0.5 (4) + 5 = 2 + 5 = 7
Point (6, 8) --> y = 0.5 (6) + 5 = 3 + 5 = 8

A professor grades a set of exams and then computes the quartiles:

If the professor curves every grade up by 10 points, then how will Q2 be affected by the curve?
I. It will increase by 10 points
ii. It will be 10 points higher than the median for the noncurved data
III It will be halfway between Q1 and Q3 for the curved data
a. I only
b. II and III
c. I, II and III
d. I and II
e. I and III
Answer:
Answer is c. I, II and II
Step-by-step explanation:
Solution:
Answer is c. I, II and II
It will be increase by 10 points and it will be 10 points higher than the median for the noncurved data. and it will be halfway between Q1 and Q3 for the curved data.
Median for noncurved data = Q2 = 80
Median for curved data = 90
It will increase by 10 points = 90
It will be 10 points higher than the noncurved data = 90-80 = 10 points
if the set contains 20 values then, noncurved data will be:
60 _ _ _ _ 70 _ _ _ _ 80 _ _ _ _ 87 _ _ _ _ 95
Curved data will be: (all grades increased by 10 points)
70 _ _ _ _ 80 _ _ _ _ 90 _ _ _ _ 97 _ _ _ _ 105
Here, we can see median = Q2 = 90, exactly, halfway between Q1 =80 and Q3 = 97
Hence, C is the right answer

Suppose you are given two quadrilaterals, ABCD EFGH. If the similarity ratio of ABCD to EFGH is 4:3, and it EH =
60, find AD
a. 45
0.90
b. 40
d. 80
Please select the best answer from the choices provided
B
Look at image^^^
Answer:
d. 80
Step-by-step explanation:
Similarity ratio of ABCD to EFGH = 4:3.
This implies that the ratio of AD to EH = 4:3
If EH = 60, then:
AD:60 = 4:3
AD/60 = 4/3
Multiply both sides by 60
AD = ⁴/3 × 60
AD = 80
