Graph: y-3=1/2(x+2)
Where would i graph this please help me just tell me the points dont go over the top with explanation
The plotted line on the graph represents all the points (x, y) that satisfy the equation [tex]\( y - 3 = \frac{1}{2}(x + 2) \)[/tex].
The graph of the equation [tex]\( y - 3 = \frac{1}{2}(x + 2) \)[/tex] has been plotted. Here are the steps to plot this graph:
1. Rearrange the equation: Convert the given equation into slope-intercept form, [tex]\( y = mx + c \)[/tex], which makes it easier to graph.
The given equation is [tex]\( y - 3 = \frac{1}{2}(x + 2) \)[/tex]. By rearranging, you get [tex]\( y = \frac{1}{2}x + 1 + 3 \)[/tex] which simplifies to [tex]\( y = \frac{1}{2}x + 4 \)[/tex].2. Calculate the y-intercept: This is the point where the line crosses the y-axis, which occurs when [tex]\( x = 0 \)[/tex]. Substituting [tex]\( x = 0 \)[/tex] into the equation gives [tex]\( y = 4 \)[/tex]. So, the y-intercept is (0, 4).
3. Calculate the slope: The slope is [tex]\( \frac{1}{2} \)[/tex] which means that for every 2 units the graph moves horizontally to the right, it moves 1 unit up.
4. Plot the y-intercept: Start at the y-intercept (0, 4) on the graph.
5. Use the slope to find another point: From the y-intercept, move right 2 units and up 1 unit to find another point on the line. You could also move left 2 units and down 1 unit for another point.
6. Draw the line: Connect the points with a straight line to complete the graph.
Emmanuel sold 16 dozen eggs last month. How many eggs did he sell in all?
Answer:
Emmanuel would have sold 192 eggs total
Step-by-step explanation:
one dozen is 12 eggs
16 dozen would be 12 x 16 = 192
Emmanuel would have sold 192 eggs total
Emmanuel sold 16 dozen eggs, and since one dozen equals 12 items, the total number of eggs sold is 192 eggs.
Explanation:The student asked how many eggs Emmanuel sold last month if he sold 16 dozen. To answer this question, we need to understand that one dozen represents 12 items. Therefore, if Emmanuel sold 16 dozens of eggs, we use multiplication to find the total.
First, identify the number of items in a dozen: 12 eggs.Next, multiply the number of dozens sold by the number of items in one dozen: 16 dozens x 12 eggs/dozen = 192 eggs.So, Emmanuel sold a total of 192 eggs last month.
Answering the additional example questions for clarification:
For g., the number is two and the unit is dozen eggs, because 'two' specifies the quantity of dozens, not individual eggs.For h., the unit is dozen eggs because that combines the measurement unit 'dozen' with what's being measured, in this case, eggs.For i., the blank should be filled with the conversion: 1 km = 1000 metersTo identify the number and unit in each quantity provided:
a. The number is one, and the unit is a dozen eggs.b. The number is 2.54, and the unit is centimeters.c. 'A box' is the number, and 'pencils' is the unit.d. The number is 88, and the unit is meters per second.1) In the diagram, l || m. If the measure of angle 3 is 120 find the measure of the following angles
a) angle 4
b) angle 6
c) angle 8
Answer:
a) 60° , b) 120° and c) 60°
Step-by-step explanation:
See the diagram attached to this question.
a) Here, ∠ 4 and ∠ 3 are supplementary angles.
So, ∠ 4 + ∠ 3 = 180° {Here, ∠ 3 is given to be 120°}
⇒ ∠ 4 = 180° - ∠ 3 = 180° - 120° = 60° (Answer)
b) Now, ∠ 3 and ∠ 6 are alternate angles and hence, ∠ 3 = ∠ 6 = 120° (Answer)
c) Here, ∠ 6 and ∠ 8 are supplementary angles.
So, ∠ 6 + ∠ 8 = 180°
⇒ ∠ 8 = 180° - ∠ 6 = 180° - 120° = 60° (Answer)

Forty-seven percent of fish in a river are catfish. Imagine scooping out a simple random sample of 25 fish from the river and observing the sample proportion of catfish. What is the standard deviation of the sampling distribution? Determine whether the 10% condition is met.
The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 catfish in the river.
The standard deviation is 0.0998. The 10% condition is not met because there are less than 250 catfish in the river.
The standard deviation is 0.9002. The 10% condition is met because it is very likely there are more than 250 catfish in the river.
The standard deviation is 0.9002. The 10% condition is not met because there are less than 250 catfish in the river.
We are unable to determine the standard deviation because we do not know the sample mean. The 10% condition is met because it is very likely there are more than 250 catfish in the river.
Answer:
Therefore the correct option is a.) The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 catfish in the river.
Step-by-step explanation:
i) Let p = 0.47
ii) therefore q = 1 - 0.47 = 0.53
iii) sample size, n =25
iii) standard deviation = [tex]\sqrt{\frac{p \times q}{n} } = \sqrt{\frac{0.47 \times 0.53}{25} } = 0.0998[/tex]
Therefore the correct option is
a.) The standard deviation is 0.0998. The 10% condition is met because it
is very likely there are more than 250 catfish in the river.
The standard deviation of the sampling distribution of the sample proportion is 0.0998. To determine whether the 10% condition is met, the total population of catfish should be at least 10 times the sample size.
Explanation:The question asks about determining the standard deviation of the sampling distribution of the proportion of catfish in a river and if the 10% condition is met for the sampling distribution to be approximately normal. First, to calculate the standard deviation of the sampling distribution of the sample proportion (p-hat), we use the formula √[(p(1-p))/n], where p is the population proportion and n is the sample size. In this case, p = 0.47, so 1 - p = 0.53, and n = 25. The standard deviation is then √[(0.47*0.53)/25], which is approximately 0.0998.
Next, the 10% condition checks whether we can consider the population large enough that the sample size doesn't affect the population proportion notably when taking without replacement. This condition states that the sample size, n, should be no more than 10% of the population. If there are indeed more than 250 fish in the river (10 times the sample size), we can be confident that the 10% condition is met. If not, the condition is not met.
Therefore, the correct response would state the standard deviation and appropriately evaluate whether the 10% condition is met based on the estimated number of catfish in the river.

of the building space?
A. 66%
B. 37.4%
C. 3.4%
D. 34%
Option D
The percentage increase of the area of the building space is 34 %
Solution:
A company is expanding its building area from 11,000 square feet to 14,740 square feet
To find: Percentage Increase
The percent increase is given by formula:
[tex]\text{Percent increase } = \frac{\text{Final value - Initial value}}{\text{Initial value}} \times 100[/tex]
From given,
Initial value = 11000
Final value = 14740
Substituting we get,
[tex]Percent\ Increase = \frac{14740-11000}{11000} \times 100\\\\Percent\ Increase = \frac{3740}{110}\\\\Percent\ Increase = 34[/tex]
Thus percentage increase of the area of the building space is 34 %

How much cashews at $1.58 per pound must be mixed with walnuts that cost 78 cents per pound to make a mixture of 40 pounds of nuts that cost $1.50 per pound?
Answer:
Cashew= 36 pounds
Walnut= 4 pounds
Step-by-step explanation:
Given: Cost of Cashew= $1.58 per pound
Cost of walnut= $0.78 per pound
Total weight of mixture= 40 Pound
Cost of mixture= $1.50 per pound.
Lets assume the amount of cashew added in the mixture be "x".
∴ Amount of Walnut in the mixture will be [tex](40-x)[/tex]
Now, forming an equation to total cost and weight of mixture.
⇒ [tex]1.58\times x+0.78 \times (40-x)= 40\times 1.50[/tex]
Using distributive property of multiplication
⇒ [tex]1.58x+31.2-0.78x= 60[/tex]
⇒[tex]0.8x+31.2= 60[/tex]
Subtracting both side by 31.2
⇒[tex]0.8x= 60-31.2[/tex]
⇒[tex]0.8x= 28.8[/tex]
Dividing both side by 0.8
⇒[tex]x= \frac{28.8}{0.8}[/tex]
∴ [tex]x= 36\ pounds[/tex]
Hence, Amount of cashew added in the mixture of nuts is 36 pounds.
Next finding the amount of walnut added in the mixture.
subtituting the value of x
Amount of walnut in the mixture= [tex](40-x)[/tex]
⇒ Amount of walnut in the mixture= [tex](40-36)= 4\ pounds[/tex]
Hence, 4 pounds of walnut added in the mixture.
Final answer:
To make a 40-pound mixture of nuts that costs $1.50 per pound, mix 36 pounds of cashews, which cost $1.58 per pound, with walnuts costing $0.78 per pound.
Explanation:
Let's approach this mixture problem using the concept of weighted averages. We know we want to make a 40-pound mixture of cashews and walnuts that costs $1.50 per pound.
The cashews cost $1.58 per pound and the walnuts cost $0.78 per pound. To find out how many pounds of cashews to mix with walnuts, we can set up the equation:
Let x be the amount of cashews needed.
Since the total weight of the mixture is 40 pounds, the amount of walnuts needed would be 40 - x pounds.
Using the equation for the total cost of the mixture: 1.58x + 0.78(40 - x) = 1.50(40),
we solve for x:
1.58x + 31.2 - 0.78x = 600.8x = 28.8x = 36Therefore, to obtain a 40-pound mixture costing $1.50 per pound, a person should mix 36 pounds of cashews with walnuts.
