Step-by-step explanation:
3x-2y=10. 4x-y=6. solve each of the pair of simultaneous linear equation by substitution method
Answer:
x = 2/5, y= -22/5
Step-by-step explanation:
4x−y=6;3x−2y=10
Step: Solve4x−y=6for y:
4x−y+−4x=6+−4x(Add -4x to both sides)
−y=−4x+6
-y/-1 = -4x +6 over -1 (Divide both sides by -1)
y=4x−6
Step: Substitute4x−6for y in 3x−2y=10:
3x−2y=10
3x−2(4x−6)=10
−5x+12=10(Simplify both sides of the equation)
−5x+12+−12=10+−12(Add -12 to both sides)
−5x=−2
-5x/-5 = -2/5 (Divide both sides by -5)
x= 2 /5
Step: Substitute 2/ 5 for x in y=4x−6:
y=4x−6
y=4 ( 2/ 5 ) −6
y= −22 /5
(Simplify both sides of the equation)
x = 2/5, y= -22/5

A random sample of 40 business days from the past year was taken from the store
records. For each day, the net income was determined. The sample standard
deviation was found to be $57.19. How many MORE business days should be
included in the sample to be 95% confident that the sample mean i of daily net
incomes is within $10 of the population mean p of daily net incomes?

The data gives the values of the 29 teams in the National Basketball Association, along with their operating incomes and revenues. Plots and correlations show that revenue predicts team value much better than does operating income. The least-squares regression line for predicting value from revenue is as follows: value = -123.298 + 4.242 revenue (a) What is the slope of this line?: 4.242 (b) The HORNETS are the NBA's most valuable team, valued at $547 million, with $147 million in revenue. Use the line to predict the value of the HORNETS from their revenue. What is the error in this prediction?: -123.298 + (4.242 * 147) = 500.276 547 - 500.278 = 46.724 (c) What is the correlation of revenue and value?: r = ?
Answer:
4.242;
$500.276 ; $46.724
Step-by-step explanation:
Given the regression equation :
value = -123.298 + 4.242 revenue
y = - 123.298 + 4.242x
y = team value ; x = Revenue
(a) What is the slope of this line?
From ;
y = mx + c
Where ; m = slope
Comparing the equation with, the model equation ;
mx = 4.242x ; Hence, slope, m = 4.242
(b) The HORNETS are the NBA's most valuable team, valued at $547 million, with $147 million in revenue. Use the line to predict the value of the HORNETS from their revenue.
Predicted value of hornets based on their revenue :
Revenue = $147,000,000
y = - 123.298 + 4.242(147)
y = - 123.298 + 623.574
y = 500.276
Predicted value is about $500.276 million.
What is the error in this prediction?:
Error = Actual - predicted value
Error = 547 - 500.276 = $46.724 million

7) Grace earns $18 per hour working as a math tutor. Write and solve an
inequality that can be used to find how many hours she must work in a week to
earn at least $378.
_6)
Answer:
The equation is 18h=378
h=21
Step-by-step explanation:
So first you have to set up the equation
so if she makes 18 dollars an hour the first part of the equation would be 18h
She made 378 dollars in one week so now the equation is 18h=378
The answer is h=21 because 378/18 is 21

6. Two numbers are in the ratio of 2:3 If the bigger number is 6. what is the smallest one
_7. What number compared with 6 is the same as 36 compared to 6?
8. There are 24 red roses for every 6 roses. How many red roses are there if there
are 8 roses?
9.There are 7 children for every 2 adults in a plaza. How many adults are there,
if there are 21 children?
10.1f 12 pencils are bought for P60, how much will you pay for 25 pencils
Ratio of two numbers = 2:3
The larger number = 6
Let the smaller number be x.
Which means :
[tex] =\tt 2 : 3 \: = \: x : 6[/tex]
[tex] = \tt \frac{2}{3} = \frac{x}{6} [/tex]
[tex] =\tt 2 \times 6 = 3 \times x[/tex]
[tex] =\tt 12 = 3x[/tex]
[tex] =\tt x = \frac{12}{3} [/tex]
[tex]\hookrightarrow\color{plum}\tt \: x = 4[/tex]
▪︎Therefore, the smaller number = 4
○=> Solution (7) :36 compared to 6 = [tex] \tt \frac{36}{6} [/tex]
Let the number be x.
Which means :
[tex] = \tt \frac{36}{6} = \frac{x}{3} [/tex]
[tex] =\tt \frac{36 \div 2}{6 \div 2} = \frac{x}{3} [/tex]
[tex] =\tt \frac{36}{6} = \frac{18}{3} [/tex]
▪︎Therefore, the fractional number [tex] \tt \frac{18}{3} [/tex] is equal to [tex] \tt \frac{36}{6} [/tex].
○=> Solution (8) :Number of Rose's for 24 red Rose's = 6
This can be written in a ratio as 24:6
Number of roses = 8
Let the number of red roses for these roses be x.
Which means :
[tex] =\tt \frac{24}{6} = \frac{x}{8} [/tex]
[tex] =\tt 24 \times 8 = 6 \times x[/tex]
[tex] =\tt 192 = 6x[/tex]
[tex] =\tt x = \frac{192}{6} [/tex]
[tex]\hookrightarrow \color{plum}\tt x = 32[/tex]
▪︎Therefore, 32 red roses are there if there are 8 roses.
○=> Solution (9) :Number of children for 2 adults = 7
This can be written in a ratio as 7:2
Number of children in the plaza = 21
Let the number of adults be x.
Which means :
[tex] = \tt \frac{7}{2} = \frac{21}{x} [/tex]
[tex] =\tt7 \times x = 2 \times 21 [/tex]
[tex] =\tt 7x = 42[/tex]
[tex] =\tt x = \frac{42}{7} [/tex]
[tex] \hookrightarrow \color{plum}\tt \: x = 6[/tex]
▪︎Therefore, 6 adults were there in the plaza.
○=> Solution (10) :Cost of 12 pencils = P60
Cost of 1 pencil :
[tex] = \tt \frac{60}{12} [/tex]
[tex] =\tt P5[/tex]
Thus, the cost of one pencil = P5
Cost of 25 pencils :
= Cost of one pencil × 25
[tex] =\tt 5 \times 25[/tex]
[tex] \color{plum}=\tt \: P \: 125[/tex]
▪︎Therefore, the cost of 25 pencils = P125
