• commutative property
• addition property of equality
• 2x=8
• distributive property
• division property of equality
• x=4
• multiplication property of equality
• subtraction property of equality
Answers
Answer:
See below
Step-by-step explanation:
[tex]2(x+5)-3 =15[/tex]
Using the distributive property in the LHS we get
[tex]2x+10-3 =15[/tex]
[tex]2x+7=15[/tex]
Now add -7 both sides. So we have the subtraction property of equality.
[tex]2x+7+(-7)=15+(-7) \text{ This is what I meant for add}[/tex]
[tex]2x+7-7=15-7[/tex]
[tex]2x=8[/tex]
Now divide both sides by 2. So we have the division property of equality
[tex]\dfrac{2x}{2} =\dfrac{8}{2}[/tex]
[tex]x=4[/tex]

The mean and standard deviation for number of battery crimes in the U.S. from 1985 to 2000 are X = 326,845 and sx = 27,569. The mean and standard deviation for number of property crimes in the U.S. for the same time period are y = 634,235 and Sy = 42,268. The correlation coefficient is r = 0.92. Find the equation for the least- squares regression line for number of property crimes compared with number of battery crimes.
A: y = 1.41 + 173,214.37x
B: y = 173,214.37 + 1.41x
C: y = 421,052.69 + 0.65x
D: y = 0.65 + 421,052.69x
E: Unable to determine the equation
Answers
Answer:
The correct answer is: A
Step-by-step explanation:
The value of the slope and intercept is:
=0.92(42268/27569)
=1.410518
a=y-bx
=634235-1.410518×326845
=173214.3716
The eququation for the least-square regression line is:
y=173214.3716 + 1.4105518x
Round to the 2 decimal place:
=173,214.37 +1.41x
The equation for the least squares regression line for number of property crimes compared with number of battery crimes is (b) y = 141x + 173214.37
How to determine the least square regression equation?The given parameters are:
Mean x, μ = 326,845 Standard deviation of x, σ = 27,569Mean y, μ = 634,235 Standard deviation of y, σ = 42,268Correlation coefficient, r = 0.92Calculate the slope (m) using:
m = r * Sy/Sx
This gives
m = 0.92 * 42268/27569
Evaluate
m =1.41051761036
Approximate
m = 1.41
The y-intercept (c) is calculated using:
c = μy -m * μx
So, we have:
c = 634235 - 1.41051761036 * 326845
Evaluate
c = 173214.371642
Approximate
c =173214.37
The least-square regression line equation is represented as:
y = mx + c
So, we have:
y = 141x + 173214.37
Hence, the equation for the least squares regression line for number of property crimes compared with number of battery crimes is (b) y = 141x + 173214.37

In exercise teacher wants each student in her class to have at least 48 ft.² of space on the floor. What is the largest number of student she will allow in a classroom with a student exercise area of this size?
Answers
Answer: D. 50 students
pls give me brainliest.
Step-by-step explanation: First we find the area of the classroom which is worked out below and it is the shape of a rectangle;
Area of a rectangle = Length * Breadth
= 60 ft * 40 ft
= 2400 ft²
Now to find the number of students that she will allow in the classroom, we have to divide the area of the classroom which is 2400 ft²by the amount of space allocated to each student which will be;
=
= 50
This means she will allow 50 students into her class.

A small submarine starts at - 1.260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes What expression represents the new position of the submarine in relation to sea level?
Answers
Answer:
The submarine is at -1260 ft.
It descends 5 ft/min for 12 min.
12 min * 5 ft/min = 60 ft.
It descended 60 ft, so you must subtract 60 ft from -1260 ft.
-1260 ft + (-5)(12) ft = -1260 ft - 60 ft = -1320 ft
The error in the last line in the problem is that (-5)(12) = -60, not 60.
The correct line is:
-1260 + (-5)(12) = -1260 - 60 = -1320

A bag had 7 orange rocks , 6 green rock , 1 white rock ,7 black rocks , and 2 yellow you randomly pull a rock from the bag ,keep it out , and then pull out another one .
What is the probability of getting a yellow rock and then a n orange rock ?
Answers
Answer:
[tex]Probability = \frac{7}{253}[/tex]
Step-by-step explanation:
Given
[tex]Orange = 7[/tex]
[tex]Green = 6[/tex]
[tex]White = 1[/tex]
[tex]Black = 7[/tex]
[tex]Yellow = 2[/tex]
Required
Probability of selecting a yellow then orange rock
From the question, we understand that the probability is that of without replacement.
Since the yellow, is first picked.
We need to determine the probability of picking a yellow rock, first.
[tex]P(Yellow) = \frac{n(Yellow)}{Total}[/tex]
[tex]P(Yellow) = \frac{2}{7 + 6 + 1 + 7 + 2}[/tex]
[tex]P(Yellow) = \frac{2}{23}[/tex]
The rock has reduced by 1;
Next is to determine the probability of picking an orange rock
[tex]P(Orange) = \frac{n(Orange)}{Total - 1}[/tex]
[tex]P(Orange) = \frac{7}{7 + 6 + 1 + 7 + 2- 1}[/tex]
[tex]P(Orange) = \frac{7}{22}[/tex]
The required probability is calculated as thus:
[tex]Probability = P(Yellow) * P(Orange)[/tex]
[tex]Probability = \frac{2}{23} * \frac{7}{22}[/tex]
[tex]Probability = \frac{14}{506}[/tex]
[tex]Probability = \frac{7}{253}[/tex]

The sports store made $564 from selling pool rafts this week (Monday-Friday). Of that amount, it made $132.56 on Monday and $107.38 on Tuesday. IT made an equal amount of money on Wednesday, Thursday, and Friday. How much money did the store make from selling pool rafts on Friday?
Answers
Answer:
Amount made from selling pool rafts on Friday is equal to $108.02
Step-by-step explanation:
Total amount made from selling pool rafts = $564
Amount made from selling pool rafts on Monday = $132.56
Amount made from selling pool rafts on Tuesday = $107.38
Let amount made on each of the days - Wednesday, Thursday, and Friday be equal to $x.
Therefore,
[tex]132.56+107.38+x+x+x=564\\239.94+3x=564\\3x=564-239.94\\3x=324.06\\x=\frac{324.06}{3}\\ x=$108.02[/tex]
So,
amount made from selling pool rafts on Friday is equal to $108.02
