Write the slope-intercept form of the equation of each line.
12x - 11y= 18
Answers
Answer:
y=[tex]\frac{12}{11}x[/tex]+[tex]\frac{-18}{11}[/tex]
Step-by-step explanation:
What you do first is you move the 12x to the other side of the equation to get
-11y=18-12x
Move the 12x to the front to get the slope intercept form set up
-11y=-12x+18
Then divide the whole thing by -11 to get the y to become by itself
y=[tex]\frac{12}{11}x[/tex]+[tex]\frac{-18}{11}[/tex]
The 12/11 will become positive and the b value will become negative
Zack has an old car. He wants to sell it for 15% off its current value. The market value is
$500. How much money would he receive in exchange for the car if he sells it at that rate?
Answers
425 dollars is 500 with a 15% discount
Answer:
$425
Step-by-step explanation:
The easiest way of calculating discount is, in this case, to multiply the normal price $500 by 15 then divide it by one hundred. So, the discount is equal to $75. To calculate the sales price, simply deduct the discount of $75 from the original price $500 then get $425 as the sales price.
Suppose that 65\ee, percent of the 310{,}000310,000310, comma, 000 citizens in a county are registered to vote. A not-for-profit organization takes an SRS of 100100100 of these citizens and finds that 67\gg, percent of those sampled are registered to vote. The organization plans on taking repeated samples like this. What are the mean and standard deviation of the sampling distribution of the proportion of citizens who are registered to vote
Answers
Answer:
mean= 0.65
standard deviation=[tex]\sqrt{\frac{0.65(0.35)}{100}[/tex]
Step-by-step explanation:
The mean of the sampling distribution is 0.65 and the standard deviation is approximately 0.004779.
What is the standard deviation?The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.
The mean of the sampling distribution of the proportion of citizens who are registered to vote is equal to the proportion of all citizens who are registered to vote, which is 65% = 0.65.
The standard deviation of the sampling distribution is equal to the standard error of the proportion, which can be calculated as follows:
standard error = √((65% × 35%) / 100)
= √((0.65 × 0.35) / 100)
= √(0.0227 / 100)
= √(0.0000227)
= 0.004779
Therefore, the standard deviation is approximately 0.004779.

Answers
Answer:
Intwo full revolutions,the wheel will travel 314 cm
Step-by-step explanation:
Recall that in one full revolution, the wheel will tavel the length of the wheel's circumference, That is:
In each revolution the wheel will cover 2 pi R = 2 * 3.14 * 25 cm = 157 cm
Therefore, in2 full revolutions, the wheel will cover twice this amount:
In 2 revolutions the wheel will travel: 2 * 157 cm = 314 cm.

State the postulate or theorem you would use to prove each pair of triangles congruent. If the triangles cannot be proved congruent, pick not possible
Answers
The triangles can be proven similar by the congruent theorem of triangles
What are Congruent Triangles?
Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the two triangles be ABC and DEF
Now , the two triangles will be similar if
The three sides are equal
So , AB = BC = CD and
DE = EF = FD
And the two triangles are congruent if
By ASA theorem - two angles are the same and a corresponding side is the same
And ,
By SAS theorem : Two sides are equal and the angle between the two sides is equal
And ,
By RHS theorem : A right angle, the hypotenuse and a corresponding side are equal
Hence , the triangles ABC and DEF is similar ΔABC ≅ ΔDEF

Fire works are fired vertically upwards from a platform 10 feet above the ground and with an initial velocity of 96 feet per second what is the highest possible point for the fireworks to explode
Answers
Answer:
Here is the answer
Step-by-step explanation:
The highest possible point for the fireworks to explode is to be considered as the 154 feet.
Calculation of the highest possible point:Since the equation is
[tex]h = -16t^2 + 96t 10[/tex]
Now based on this, we have to determine the axis of symmetry
So,
[tex]t = -b \div 2a\\\\= -96 \div 32[/tex]
= 3
Now
[tex]= -16(3)^2 + 96(3) + 10[/tex]
= 154 feet
hence, The highest possible point for the fireworks to explode is to be considered as the 154 feet.
