Find the equation of the line with slope m
= -1/2 that contains the point (-10, 1).
In slope intercept form
Answer:
y = - [tex]\frac{1}{2}[/tex] x - 4
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )
~~~~~~~~~~~~~~~~~
m = - [tex]\frac{1}{2}[/tex]
( - 10, 1 )
y - 1 = - [tex]\frac{1}{2}[/tex] [ x - ( - 10 )]
y - 1 = - [tex]\frac{1}{2}[/tex] x + ( - [tex]\frac{1}{2}[/tex] )(10)
y = - [tex]\frac{1}{2}[/tex] x - 4

A multiple choice test contains 25 questions with 5 answer choices. What is the probability of correctly answering 8 questions if you guess randomly on each question?
Answer: 0.0623
Step-by-step explanation:
The probability of correctly answering 8 questions if you guess randomly on each question is 0.062348.
It is given that multiple choice test contains 25 questions with 5 answer choices.
To find probability of correctly answering.
What is probability?The extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases possible.
Given that:
The probability of each correct answer is [tex]p_{s}[/tex][tex]=\frac{1}{5}[/tex]
The probability of 8 successful answers in 25 independent trials for a binomial probability distribution is:
p(k|n)=[tex]\frac{n!}{(n-k)!*n!}[/tex][tex]p_{s}^{k} (1-p_{s})^{n-k} \\[/tex]
p(8|25)=[tex]\frac{25!}{(25-8)!*8!}[/tex][tex]{\frac{1}{5} }^{k} (1-1/5)^{25-8} \\[/tex]
p(8|25)=0.062348
So, the probability of correctly answering 8 questions if you guess randomly on each question is 0.062348.

Note:if you need to ask any question please let me know.Suppose that angle P = 3x + 14 and angle Q = 3x - 27. If these angles are supplementary, angle Q would need to be ___ degrees.
Answer:
Q = 69.5 degrees
Step-by-step explanation:
3x + 14 + 3x - 27 = 180
6x - 13 = 180
6x = 193
x = 32.1667
Q = 3(32.1667) - 27
Q = 69.5

MN has endpoints at M(2,5) and
N(-4, 3). In what quadrant is the midpoint
of MN?
A Quadrant |
B Quadrant II
C Quadrant IIl
Answer:
quad 2
Step-by-step explanation:
Midpoint = (x1 + x2)/2,(y1 + y2)/2
x1 = 2
x2 = - 4
y1 = 5
y2 = 3
midpoint = (2 - 4)/2,(5 + 3)/2
midpoint = -2/2, 8/2
midpoint = -1,4
-1 for x puts you in quad 2 or 3
4 for y puts you in quad 2 because you are going up.
The final answer is in quad 2

1/4 luke's marbles are white, 3/8 are blue, and the rest are 30 yellow marbles. How many of the marbles are white.
Answer:
It is 20 white marbles
step by step explanation:
Fraction of the yellow marbles:
[tex]1 - \frac{1}{4} - \frac{3}{8} = \frac{3}{8} [/tex]
let total number of marbles be x :
[tex]{ \sf{ \frac{3}{8} \: of \: x = 30 \: yellow \: marbles}} \\ \\ \frac{3}{8} \times x = 30 \\ \\ 3x = 30 \times 8 \\ 3x = 240 \\ x = 80[/tex]
Total marbles = 80 marbles
for white marbles:
[tex] = \frac{1}{4} \times 80 \\ \\ = 20[/tex]

Find the equation of the line that is parallel to y = 2x - 3 and passes through the
point (0,7).
Answer: [tex]y=2x+7[/tex]
Step-by-step explanation:
Let's introduce couple variables [tex]m_{1}[/tex] (slope of your equation) and [tex]m_{2}[/tex] (slope of the equation we need to find.
Parallel lines have the same slope, therefore: [tex]m_{1} = m_{2}[/tex], where [tex]m_{1}=2[/tex] and this means that [tex]m_{2} = 2[/tex] as well.
Given that we will use point-slope equation form with the point (0,7):
[tex]y-y_{1} =m(x-x_{1} )\\[/tex] where [tex](x_{1}, y_{1} )[/tex] is the point
Let's substitute:
[tex]y-7=2(x-0)\\[/tex]
And calculate:

Now we just need to isolate [tex]y[/tex] by subtracting 7 from both sides:
[tex]y=2x+7\\[/tex]
That's it!
Here's the graph to show the results:
