Answer:
y = -1/2x - 5/2
Step-by-step explanation:
y = 2x – 1
Current slope is 2, perpendicular is opposite inverse which is -1/2.
y-intercept through point (-5, 0):
y = mx + b
0 = -1/2(-5) + b
0 = 5/2 + b
b = -5/2
Use the perpendicular slope and b above to form new equation of line:
y = mx + b
y = -1/2x - 5/2
There are only 6 blue pens, 5 green pens and 8 red pens in a box.
One pen is taken at random from the box.
Write down the probability that this pen is blue.
Answer:
0.316
Step-by-step explanation:
Probability = (number of outcomes)/(total number of outcomes)
In this case,
the total number of outcomes is 6+5+8 = 19, and
the number of outcomes for getting a blue pen = 6
Hence,
P(blue) = 6/19 = 0.31578947368 ≈ 0.316

Answer:
±1/4, ±1/2, ±1, ±5/4, ±2, ±5/2, ±5, ±10
Step-by-step explanation:
The rational root theorem tells you possible rational roots of this equation would be ...
±(divisor of 10)/(divisor of 4)
The divisors of 10 are 1, 2, 5, 10. The divisors of 4 are 1, 2, 4. Then the possible rational roots are ...

The trigonometric function sin is the ratio of perpendicular to hypotenuse thus sinθ = 5/13.
What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
As per the given right angle triangle,
By sine function.
sinθ = perpendicular/hypotenuse
sinθ = 5/13

1. A senator is thinking about running for president. But she will only do so if more than 60% of the voters view her favorably. She gathers some data to see if she has this level of support. Which statistical method would be best for her to use?
The senator is faced with the making a decision to run for President, based
on the conclusion she can make from the data she gathers.
The statistical method that would be best for her to use is inferential
statistic method such as finding the percentage of supporters she has to a
given confidence level.
Reason:
The two main types of statistical methods are;
Inferential statistics methods; Theses are methods used to reach a
conclusion that extends past the given or available data.
Descriptive statistics methods; Theses are statistical method used as a
summary of a data set.
Given that the senator is trying to draw conclusion based on the data she
gathers, she should use inferential statistic method.
The type inferential statistic method that can be used is the confidence
interval.
From the data collected, the proportion of voters that view her favorably is
used at a given confidence level to determine the true proportion of voters
that view her favorably.
Therefore;
The statistical method that would be best for her to use is the
finding of the confidence interval which is a inferential statistic method.
