Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4

From the numbers 1, 2, 3, 4, 5, what is the probability of choosing an even number at random?
Answer:
2/5
Step-by-step explanation:
There are only 2 even number in the set out of 5 numbers.
The probability of selection even number at random is 2/5.
What is probability?
Probability is possibility that deals with "occurrence of random event at a time".
According to the question,
From the numbers 1,2,3,4,5
Number of sample space = 5
Number of even numbers = 2
Probability of an event = [tex]\frac{sum of favorable events}{Total number of events}[/tex]
In order to find probability of selection even number at random:
=2/5.
Hence, the probability of selection even number at random is 2/5.

What's the probability of rolling a prime number on a fair die
Answer:
50% chance
Step-by-step explanation:
if it's a six-sided die, the options are 2, 3, and 5. that's three numbers out of six, or half (50%)
Answer:
1/2 ; 50%
Step-by-step explanation:
Probability is number of desired outcomes/number of total outcomes.
In a fair die, there are 6 total outcomes.
Now, let's find how many desired outcomes there are.
We can do this by naming the prime numbers form 1-6.
Prime numbers are numbers that are divisible by 2 positive integers: 1 and itself.
This means that 1, 4, and 6 are not prime numbers.
The prime numbers are: 2, 3, and 5.
So there are 3 desired outcomes.
That means the probability would be 3/6
This can be simplified to 1/2, or 50%
A square has one of its sides increased by 7 inches and the other side decreased by 4 inches. Which of the following represents the area of the square?
Answer:
Step-by-step explanation:
both the length and the width of a square is the same measurement.
so if both measured to "x" then that means one side increase +7.
so one side is x + 7
and the other side decreased -4
so the other side is x - 4
area of square = length x width or just one of the sides to the power of 2
so (x+7) * (x-4) = Area
x^2 + 3x - 21 = area
Answer:
x^2-11x+24
Step-by-step explanation:
The area of a quad is lw
So, the formula would be (x-7)(x-4)
When you multiply it, it turns to be x^2 - 11x + 24
I think thats the answer

Answer: A. Negative correlation
Step-by-step explanation:
A P E X
The scatterplot that represents the monthly values of stock ABC can be approximated by a line with a positive slope represents positive correlation. The correct option is C.
What is correlation?The relationship between variables is described by correlation. It can be either strong or weak, as well as positive or negative.
Correlations show that there is a relationship between two variables, but one does not always cause the other to change.
A positive correlation indicates that as one variable increases, so does the other.
In this case, the scatterplot of the monthly values of stock ABC can be approximated by a line with a positive slope, indicating that as the stock's value increases over time, so does the corresponding month. As a result, it is a positive correlation.
Thus, the correct option is C.

Ellie’s eats 1/4 cups of raisins everyday. If she buys a package that has 6 cups of raisins,how many days of raisins is that ?
Answer:
24
Step-by-step explanation:
Answer:
24 days
Step-by-step explanation:
Alright, so you can set an equation where x is the amount of days this package of raisins can last. Your equation would be 6=1/4x. Now, you solve. Bring the 1/4 over by dividing both sides by it. You get x=24, which is the answer.

Step-by-step explanation:
The results of a survey indicate that the true proportion of households who recycle paper products
is likely in the interval (0.61,0.7).
What is the point estimate of the proportion of households who recycle paper?
Enter your answer, as a decimal, in the box.
Answer:
[tex] 0.61 \leq p \leq 0.70[/tex]
And for this case we can estimate the proportion of households who recycle paper is given by:
[tex] \hat p = \frac{Upper +Lower}{2}[/tex]
And replacing we got:
[tex] \hat p =\frac{0.7+0.61}{2}= 0.655[/tex]
And for this case the answer is 0.655 for the proportion of households who recycle paper
Step-by-step explanation:
For this case we know that the confidence interval for the proportion of interest is given by:
[tex]\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex]
And for this case the confidence interval is given:
[tex] 0.61 \leq p \leq 0.70[/tex]
And for this case we can estimate the proportion of households who recycle paper is given by:
[tex] \hat p = \frac{Upper +Lower}{2}[/tex]
And replacing we got:
[tex] \hat p =\frac{0.7+0.61}{2}= 0.655[/tex]
And for this case the answer is 0.655 for the proportion of households who recycle paper

Answer:
A) 9
Step-by-step explanation:
First you need to find the measure of angle c
Since it's a quadrilateral, the interior angles add up to 360 degrees
Now there's two right angles and one 99 degree angle
Add those and subtract from 360
360 - (90+90+99) = 81
C = 81 degrees
However x is the root of c so root 81 is 9
