slope=4/5 passing though (5,3) whats the point slope form
slope intercept form
Answer:
4
Step-by-step explanation:
The slope-intercept form of the equation is y = (4/5)x -1.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that slope=4/5 passing through (5,3). The equation of the line can be written as,
y = mx + c
3 = ( 4 x 5/5) + c
c =-1
The equation will be:-
y = mx + c
y = (4/5)x -1

Compare the tow numbers below 9.657 and 6.475 how much smaller is the 7 in the second number
Step-by-step explanation:
Given the values 9.657 and 6.475. Before we can know how much smaller is the 7 in the second number compare to the first, we need to get their place values first.
For 9.657
The place value of 7 in this value is 7 thousandth
7 thousandth = 7/1000 = 0.007
For 6.475
The place value of 7 in this value is 7 hundredth
7 hundredth= 70/1000 =7/100 = 0.07
Hence the value of 7 in the first is smaller that that of the second.TO know by how much, we will take the ratio of the two values
Find their ratios:
0.07/0.007 = 7/100 ÷ 7/1000
= 7/100×1000/7
= 7000/700
= 10
This means that the place value of 7 in 9.657 is 10 times smaller than the value of 7 in 6.475
b is (4,-10) and c is (10,-4) what is the length of bc ? Explain with full detail ! Pls
Answer:
m=1
Step-by-step explanation:
y=mx+b
m = y 2 − y 1/ x2 − x 1
m = − 4 − ( − 10 )/ 10 − ( 4 )
m = − 2 − 5 ⋅ − 1/ − 1 (− 5 + 2 )
m = 3 − 1 /( − 5 + 2 )
Add
− 5 and 2
m = 3/ − 1 ⋅ − 3
Multiply
− 1 by − 3
m = 3/ 3
Divide 3 by 3 .
m = 1

A pair of shoes that normally sells for $82.88 goes on sale for 35% off what is the final sale price
Answer:
$29.01
Step-by-step explanation:
According to my calculations, an item with an original price tag of $82.88 that is marked down by 35% will have a sales price of $53.87 -- a savings of $29.01.
(1 - (30 / 100)) * $30.00
Sale Price = (1 - 0.30) * $30.00
Sale Price = 0.70 * $30.00
Sale Price = $21.00
136 cars were sold during the month of April. 71 had air conditioning and 72 had automatic transmission. 55 had air conditioning only, 56 had automatic transmission only, and 9 had neither of these extras. What is the probability that a randomly selected car had automatic transmission or air conditioning or both
Answer:
0.93382
Step-by-step explanation:
Let
The event where a car has air conditioning (ac) be A
The event where a car has an automatic transmission be B
[tex]P(\text{Car has ac and cars that don't have automatic transmission})=P(A\cap B')=\dfrac{71}{136}[/tex]
[tex]P(\text{Car has car has an automatic transmission and no ac})=P(B\cap A')=\dfrac{56}{136}[/tex]
[tex]P(\text{Car has no ac and cars that don't have automatic transmission})=P(A'\cap B')=\dfrac{9}{136}[/tex]
The probability of a chosen car which has ac or automatic transmission or both
[tex]P(A\cup B)=1-P(A\cup B)'\\\Rightarrow P(A\cup B)=1-P(A'\cap B')\\\Rightarrow P(A\cup B)=1-\dfrac{9}{136}\\\Rightarrow P(A\cup B)=0.93382[/tex]
The probability that a randomly selected car had automatic transmission or air conditioning or both is 0.93382

a concrete stepping stone measures 20 square inches. what is the area of 30 such stones?
Answer:
12000
Step-by-step explanation:
If you mean one side of the stepping stone is 20 inches then you would multiply 20 by 20 to get the area of one, since that would be multiplying length times width (the area formula). The area of one would result in 400 and you would then multiply this by the thirty tiles (400 times 30) to get 12000.
Answer:
12000

What is the equation of the line that passes through the point (-6, -2) and has a
slope of -1/6?
The equation of the line that passes through the point (-6, -2) and has a slope of -1/6 will be y = -(1/6)x - 3.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope is - 1/6. Then the equation is given as,
y = -1/6 x + c
The equation passes through (-6, -2). Then we have
-2 = - (1/6) (-6) + c
- 2 = 1 + c
c = - 3
Then the equation is given as,
y = - (1/6)x - 3
The equation of the line that passes through the point (-6, -2) and has a slope of -1/6 will be y = -(1/6)x - 3.

You are riding on a zip line. Your speed is 15 miles per hour. What is your speed in feet per second?
Answer:
22 feet per second
Step-by-step explanation:
The speed on the zip line is 22 feet per second.
let's use the conversion rate below
1 miles = 5280 foot
1 hour = 3600 seconds
The rate is measured in miles per hour. Let's convert it to feet per seconds. Therefore,
Let convert the distance first
1 miles = 5280 foot
15 miles = ?
cross multiply
distance in miles = 5280 × 15 = 79200 foots
let convert the hours to seconds
3600 seconds = 1 hour
Therefore,
speed in foot per seconds = 79200 / 3600 = 22 ft/secs

What is the equation of a line that has a slope of -5 and passes through the point (0, 2)?
A.y = -5x
B.y = 2x - 5
C.y = -5x + 2
Answer: y=-5x+2
Step-by-step explanation: Luckily for you, they already pretty much gave you all the information you need for this problem. Keep in mind that the standard form for linear equations is y=mx+b, where m is slope and b is figure 0, or the y-intercept. So, all you have to do is substitute the values for the given information. You know that -5 is the slope, m, and (0,2) is the y-intercept, or b (you know that this is the y-intercept because x is at zero). So, you'd be left with y=-5x+2.

what is 14 divided by 2/7 in simplest from
Answer:
98/2
Step-by-step explanation:
The numbers in 14 divided by 2/7 are labeled below:
14 = whole number
2 = numerator
7 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
14 x 7
2
=
98
2
Thus, the answer to 14 divided by 2/7 in fraction form is:
98
2
To make the answer to 14 divided by 2/7 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
98 / 2 = 49
The answer is rounded to the nearest two decimal points if necessary.
98/2 can be simplified to 49/1.
49/1 is an improper fraction and should be written as 49.
the simplest form of 14 divided by 2/7 is 49.
To divide 14 by 2/7, we can convert the division operation into multiplication by taking the reciprocal (flipping) of the divisor. The reciprocal of 2/7 is 7/2. So, we have 14 multiplied by 7/2.
To simplify this further, we can cancel common factors between the numerator of 14 and the denominator of 2. Both 14 and 2 share a common factor of 2. Dividing both by 2, we get 7 and 1 respectively.
Therefore, the division 14 divided by 2/7 simplifies to 7 multiplied by 7/1, which equals 49. Thus, the simplest form of 14 divided by 2/7 is 49.

Complete Question
Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal places
x 1 2 3 4 5
P(x) 0 0.31 0.12 0.23 0.4
Answer:
The value is [tex]\sigma = 0.89[/tex]
Step-by-step explanation:
From the question we are told that
The probability distribution is
x 1 2 3 4 5
P(x) 0 0.31 0.12 0.23 0.4
So
[tex]x^2[/tex] 1 4 9 16 25
Generally the mean is mathematically represented as
[tex]E(X) = \sum [x * P(x)][/tex]
=> [tex]E(X) = (1 * 0) + (2 * 0.31 ) + (3 * 0.12 ) + (4 * 0.23) + (5 * 0.4 )[/tex]
=> [tex]E(X) = 3.9[/tex]
Generally
[tex]E(X^2) = \sum [X^2 * P(x)][/tex]
=> [tex]E(X^2) = (1 * 0) + (4 * 0.31 ) + (9 * 0.12) + (16 * 0.23) + (25 * 0.4)[/tex]
=> [tex]E(X^2) =16[/tex]
Generally the variance of this probability distribution is
[tex]V(X) = E(X^2) - [E(X)]^2[/tex]
[tex]V(X) = 16 - 3.9^2[/tex]
[tex]V(X) = 0.79[/tex]
Generally the standard deviation of this probability distribution is
[tex]\sigma = \sqrt{V(x)}[/tex]
=> [tex]\sigma = \sqrt{0.79}[/tex]
=> [tex]\sigma = 0.889[/tex]
