0.8 divided by 0.6 then round to nearst hundredth
Answer: 1.33
Step-by-step explanation:
0.8 divided by 0.6= 1.33333333333
3 is in the hundredths place and 3 is in the thousandths place.
Since the digit in the thousandths place (3) is less than 5, the digit in the hundredths place (3) does not change.
The digits to the right of the hundredths place are dropped.
1.33333333 rounded to the nearest hundredth (two decimal places) = 1.33.
a hypothesis test is conducted at the 0.05 level of significance to test whether or not the population correlation is zero. if the sample consists of 41 observations and the correlation coefficient is 0.60, what is the computed value of the test statistic? round to two decimal places.
The computed value of the test statistic is 4.65 or 4.7
Information given in the query:
significance level = 0.05
Sample size is 41 observations, and the correlation value is 0.60.
Now,
Using the formula, the test statistic to determine whether the population correlation is zero is provided.
:

Answer: A) x^2+y^2 B) x^3+y^3 C) a^2b^2c^2 D) c^2/d^2
Step-by-step explanation:
For A, you add all the powers. This is because the bases are the same. Any number or letter without a visible power on top most likely means that is has a power of 1. Because this is a multiplication question, you have to add the powers. (Example n*n = n^2 or n^3*n^7 = n^10)
This is same for B.
For C, you multiply abc by abc so it's a*a, b*b, c*c. This is because they are inside a bracket. Anything inside the bracket that has a power outside the bracket is multiplied by itself.
For D, you multiply c and d so it's c*c, d*d. This is the same as C.

Cathy has 48m of fencing to make a rectangular pen for her pets. What is the
maximum area?
The area of the square will be 100 square meters. Then the dimensions of the pen of the rectangle will be 10 by 10 which is a square.
What is the area of the square?
Let a be the side length of the square.
Then the area of the square will be
Area of the square = a² square units
Cathy has 40 meters of fencing to build a rectangular pen for her pets.
For the maximum area of the rectangle, the length and width should be congruent.
40 = 4a
a = 10
Then the area of the square will be
A = 10²
A = 100 square meters
The dimensions of the pen of the rectangle will be 10 by 10 which is a square.

Answer:
2. y = x + 13
Step-by-step explanation:
Your points are: (-4, 9) and (2, 15)
To write an equation of a line from two ordered pairs, you first find the slope (m)
To find the slope, you do y2 - y1 / x2 - x1
(-4 is x1, 9 is y1) (2 is x2, 15 is y2)
Plug in the numbers:
15 - 9 / 2 - (-4) ----------------------> 6/6 ----------> 1, m = 1
The next equation we'll use is y - y1 = m(x - x1)
and slope intercept form is y = mx + b
Pick either ordered pair to plug in the coordinates, but this time I'll use
(2, 15) -----> 2 is x1, 15 is y1
y - 15 = m(x - 2)
Since we already know the slope, m, we can simplify the equation.
y - 15 = 1(x - 2)
Distributive property
y - 15 = x - 2
Add 15 on both sides,
y = x + 13

Travis rents an apartment in a historic, all-brick building downtown. The value of the belongings in the apartment is about $11,000. If Travis wishes to insure his belongings while renting, how much will he have to pay for insurance per year? Use the table above to solve.
I did:
it fell under 0.39 for building and 0.43 for contents so I did
0.39 x 12=4.68 then added the 100 dollar bonus and got $104.68
The amount of insurance that Travis will have to pay for the year is of:
$47.3.
What is the amount of insurance that Travis has to pay?He is renting the apartment, in which the belongings are worth $11,000, hence the insurance will be paid over that amount.
The number of hundredths in $11,000 is given by:
11000/100 = 110.
He pays an insurance of $0.43 for each $100 in belongings, hence the total insurance is of:
0.43 x 110 = $47.3.
There is no information regarding the value of the building, hence we are going to consider that he does not pay insurance for the building.
This insurance was taken from the table, as the apartment is in the city (downtown), and all brick, hence the coefficient is of 0.43.

a certain area of the eastern united states is, on average, hit by 6 hurricanes a year. find the prob- ability that in a given year that area will be hit by (a) fewer than 4 hurricanes; (b) anywhere from 6 to 8 hurricanes.
By applying probability method in a Poisson distribution, we find out that the probability that in a given year that area will be hit by fewer than 4 hurricanes is 0.1512 and the probability that in a given year that area will be hit by anywhere from 6 to 8 hurricanes is 0.4015.
It is given that -
On an average, Eastern United States is hit by 6 hurricanes in a year.
We have to find out -
(a) Probability that in a given year that area will be hit by fewer than 4 hurricanes
(b) Probability that in a given year that area will be hit by anywhere from 6 to 8 hurricanes
This is a case of probability which relates to Poisson distribution that provides probability of any random event that occurs within a specific time interval.
Let us assume the number of hurricanes is represented by [tex]X[/tex]. The Poisson distribution can be represented as -
[tex]P(X) = \frac{(lambda)^{X}*e^{-lambda}}{X!}[/tex] -------(1)
Here, [tex]X\\[/tex] = 1,2,3,...
lambda = Average = 6 (in this question)
[tex]e[/tex] = 2.718
(a) Probability that in a given year that area will be hit by fewer than 4 hurricanes
[tex]P(X < 4) = P(X=0) +P(X=1)+P(X=2)+P(X=3)\\= \frac{6^{0}*e^{-6}}{0!}+\frac{6^{1}*e^{-6}}{1!}+\frac{6^{2}*e^{-6}}{2!}+\frac{6^{3}*e^{-6}}{3!}\\=0.0025+0.0149+0.0446+0.0892\\=0.1512[/tex]
Thus, the probability that in a given year that area will be hit by fewer than 4 hurricanes is 0.1512.
(b) Probability that in a given year that area will be hit by anywhere from 6 to 8 hurricanes
[tex]P(6\leq X\leq 8)=P(X=6)+P(X=7)+P(X=8)\\=\frac{6^{6}*e^{-6} }{6!}+\frac{6^{7}*e^{-6} }{7!}+\frac{6^{8}*e^{-6} }{8!}\\=0.1606+0.1376+0.1033\\=0.4015[/tex]

use the properties of vector addition and scalar multiplication from the following theorem. properties of vector addition and scalar multiplication in rn let u, v, and w be vectors in rn, and let c and d be scalars.
The set R^2 with x ≤ 0 and y ≤ 0 is not a vector space.
The 10th axiom cv∈ V does not hold
Let u, v and w be vectors in the vector space V, and let c and d be scalars. A set S is defined as a vector space if it satisfies the following conditions:
1. u+ v ∈V
2. v + w = w + v
3. (u + v) + w = u + (v + w)
4. v + 0 = v = 0 + v
5. v + (−v) = 0
6. 1v = v
7. c(dv) = (cd)v
8. c(v + w) = cv + cw
9. (c + d)v = cv + dv
10. c v ∈V
Given the set of all vectors x, y in R^2 with x ≤ 0 and y ≤ 0
If the scalar c is such that c<0 then c v ∉R^2as cv>0

Answer:
10x + 12y = 100
x + y = 9
Step-by-step explanation:
Define Variables:
Let x = the number of small boxes purchased
Let y = the number of large boxes purchased
Each small box has 10 granola bars, so small boxes have 10x granola bars.
Each large box has 12 granola bars, so large boxes have 12y granola bars. Therefore, the total number of granola bars 10x + 12y equals 100:
10x + 12y = 100
Since a total of 9 boxes were purchased, we know x + y must equal 9.
x + y = 9

What is a slope?The slope of a line can be used to calculate its steepness. The slope or gradient of a line is a number that indicates its direction and steepness.The slope is calculated by dividing the vertical change by the horizontal change between any two distinct points on a line. The ratio is sometimes written as a quotient, which produces the same number for every two distinct points on the same line.How to find the output of the linear function?A linear equation is given by ,
f(x) = mx+ c ---(1)
From the table,
x value increases by 1
y value decreases by 1
The function's slope, or the coefficient that converts an increase in x to an increase in y, is represented by the letter m.So, the coefficient slope(m) magnifies the decrease by 1Substituting slope m = - 1 in (1)
f(x) = -x+ c ---(2)
Substitute (1, 2) in (2)
2 = -1 +c
c = 2 + 1
c = 3
Substitute slope m and c in (2)
f( x ) = - x + 3
