The following are the solution to this question:
Step-by-step explanation:
In the given question, some of the values are missing which is defined in the attached file please find it.
In this question, the data is used to represent a standardized exam's scores, which is normally spread out into the test score that is 1530 and its standard deviation 316.
Formula:
[tex]\to z=\frac{X- \mu}{\sigma } \\[/tex]
If the value of z-score= 1930
[tex]\to z =\frac{1930- 1530}{316 } \\\\ \to z =\frac{400}{316 } \\\\ \to z = 1.27[/tex]
The z-score is 1.27
If the value of z-score= 1250
[tex]\to z =\frac{1250- 1530}{316 } \\\\ \to z =\frac{-280}{316 } \\\\ \to z = -0.886[/tex]
The z-score is -0.886
If the value of z-score= 2250
[tex]\to z =\frac{2250- 1530}{316 } \\\\ \to z =\frac{720}{316 } \\\\ \to z = 2.27[/tex]
The z-score is = 2.27
If the value of z-score= 1420
[tex]\to z =\frac{1420- 1530}{316 } \\\\ \to z =\frac{-110}{316 } \\\\ \to z = -0.348[/tex]
The z-score is = -0.348

The value of x in the equation (12x − 36) = 5x + 18 is .
Answers
Answer:
[tex]x = \frac{54}{7} [/tex]Step-by-step explanation:
(12x − 36) = 5x + 18
First of all remove the parenthesis
That's
12x - 36 = 5x + 18
Next subtract 5x from both sides of the equation
We have
12x - 5x - 36 = 5x - 5x + 18
7x - 36 = 18
Add 36 to both sides of the equation
That's
7x + 36 - 36 = 18 + 36
7x = 54
Divide both sides by 7
[tex] \frac{7x}{7} = \frac{54}{7} [/tex]
We have the final answer as
[tex]x = \frac{54}{7} [/tex]
Hope this helps you
Answer: x=54/7
Step-by-step explanation:
To find the value of x, we need to use algebraic properties to isolate x.
12x-36=5x+18 [subtract both sides by 5x]
7x-36=18 [add both sides by 36]
7x=54 [divide both sides by 7]
x=54/7
Now, we know that x=54/7.
* For his phone service, Goran pays a monthly fee of $24, and he pays an additional $0.06 per minute of use. The least he has been charged in a month is $93.96
*What are the possible numbers of minutes he has used his phone in a month?
*Use m for the number of minutes, and solve your inequality for m.
Answers
Answer:
[tex]m \geq 1166[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = \$24[/tex]
[tex]Charges = \$0.06[/tex] per minute
[tex]Least\ Monthly\ Charges = \$93.96[/tex]
Required
Determine the possible number of minutes
If for 1 minute, he's charged $0.06;
He'll be charged $0.06m for m minutes
Representing this as an inequality, we have:
[tex]Base\ Amount + m\ Charges \geq\ Least\ Monthly\ Charges[/tex]
[tex]24 + 0.06m \geq 93.96[/tex]
Solve for 0.06m
[tex]0.06m \geq 93.96 - 24[/tex]
[tex]0.06m \geq 69.96[/tex]
Solve for m
[tex]m \geq 69.96/0.06[/tex]
[tex]m \geq 1166[/tex]
This implies that, he's charged for at least 1166 minutes

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 1/5 ÷ 3/4 be equation (1)
On simplifying the equation , we get
A = 1/5 x 4/3
A = 4 / ( 5 x 3 )
The value of A = 4 / 15
Therefore , the value of A is 4/15
Hence , the equation is A = 4/15

A merchant mixed 10 lb of a cinnamon tea with 2 lb of spice tea. The 12-pound mixture cost $13. A second mixture included 16 lb of the cinnamon tea and 8 lb of the spice tea. The 24-pound mixture cost $28. Find the cost per pound of the cinnamon tea and of the spice tea.
Answers
Step-by-step explanation:
Let's say c is the price of cinnamon tea, and s is the price of spice tea.
10c + 2s = 13
16c + 8s = 28
Divide the second equation by 4:
4c + 2s = 7
Subtract from the first equation:
6c = 6
c = 1
Use any equation to find s.
s = 1.5
Therefore, the cinnamon tea costs $1 per pound and the spice tea costs $1.50 per pound.

Answers
Answer:
18
Step-by-step explanation:
In the linear regression equation y=a+bx, slope coefficient b represents average unit increases in y variable due to unit increase in x variable.
In the given equation ŷ = 84 + 18x, b=18 represents average unit increases in gas used due to unit increase in degree day.
Hence,on average, gas used increase by 18 for each additional degree-day.

A chain weighs 9 pounds per foot. How many ounces will 5 inches weigh? Round your answer to the
nearest tenth as needed.
Answers
Answer:
60 ounces.
Step-by-step explanation:
A chain weighs 9 pounds per foot.
We are to find the number of ounces 5 inches weigh.
First we find how many feet are in 5 inches.
1 foot = 12 inches
how many feet? = 5 inches.
Cross-multiplying gives;
[tex]\frac{5}{12} * 1 = \frac{5}{12}[/tex] feet
1 foot of the chain = 9 pounds
[tex]\frac{5}{12}[/tex] feet = how many pounds?
Cross-multiplying gives;
[tex]\frac{5}{12} * 9 = 3.75[/tex] pounds
1 pound = 16 ounces
3.75 pounds = how many ounces?
Cross-multiplying gives;
[tex]\frac{3.75 * 16}{1} = 60[/tex] ounces.
The number of ounces will 5 inches weigh is 66.667 oz.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A chain weighs 9 pounds per foot.
We know that
1 foot = 12 inches.
1 pound = 16 ounces.
Now based on this,
= 5 inches 1/12 x foot/ inches x 10 x pound/ feet x 16
= 5 x 10 x 16 / 12
= 66.667 oz.
Hence, the chain weight 66.6667 oz.
