Last weekend, nina mowed lawns and received $60. This weekend she mowed 6 lawns and received $90. what is the constant of proportionality?
Answer:
$15
Step-by-step explanation:
It is given that,
Last weekend, Nina mowed 4 lawns and received $60. This weekend she mowed 6 lawns and received $90.
We need to find the constant of proportionality.
First we can find the money received when she mowed 1 lawn for last weekend.
4 lawns = $60
1 lawn = $15
Then, we will find the money received when she mowed 1 lawn for this weekend.
6 lawns = $90
1 lawn = $15
Hence, the constant of proportionalityis $15.
In a two-factor experiment with 2 levels of factor A and 2 levels of factor B, three of the treatment means are essentially identical and one is substantially different from the others. What result(s) would be produced by this pattern of treatment means?a. a main effect for factor Ab. a main effect for factor Bc. an interaction between A and Bd. The pattern would produce main effects for both A and B, and an interaction
Answer:
The pattern would produce main effects for both A and B, and an interaction
Step-by-step explanation:
When there is a two factor experiment having two types of level of factor A and the two level of factor B also the three of the treatment that are similar and the one is totally distinct from the others
So here the treatment pattern would be the pattern in which the important and main impact would be generated for both A and B and then an interaction
hence, the last option is correct
In a sample of 57 temperature readings taken from the freezer of a restaurant, the mean is 29.6 degrees and the population standard deviation is 2.7 degrees. What would be the 80% confidence interval for the temperatures in the freezer?
Answer:
(29.14 ; 30.06)
Step-by-step explanation:
Given that'
Sample size (n) = 57
Mean (m) = 29.6
Population standard deviation (σ) = 2.7
Confidence interval = 80%
= (1 - 0.8) / 2 = 0.1
Mean ± z * σ/√n
Using the Z probability calculator : Z0. 1 = 1.28
Hence,
29.6 ± 1.28 * (2.7 / √57)
29.6 - (1.28 * 0.3576237) ; 29.6 + (1.28 * 0.3576237)
29.142241664 ; 30.057758336
(29.14 ; 30.06)

0.714 mile per hour
Step-by-step explanation:
slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)
Mile per hour: 5/7 cross multiply with x/1, make into an equation:
7x=5 x 1
7x = 5
x = 0.714

Answer: 2nd one trust me
Step-by-step explanation:
From Allen (1990, 113, 162). The interactive computer system at Gnu Glue has 20 communication lines to the central computer system. The lines operate independently and the probability that any particular line is in use is 0.6. () What is the probability that 10 or more lines are in use? Compare the exact binomial solution and the normal approximation solution to this problem. (ii) Do the assumptions needed for the normal approximation make sense?
Answer:
Binomial = 0.8724
Normal approximation = 0.873
Step-by-step explanation:
Given that :
Sample size (n) = 20
p = 0.6
q = 1 - p = 1 - 0.6 = 0.4
.using normal approximation :
Mean = np
Mean (m) = 20 * 0.6 = 12
Standard deviation (s) = √npq
s = √(20 * 0.6 * 0.4) = 2.1908902
Probability of 10 or more lines in use :
p(x ≥ 10)
Applying for correction:
p(x ≥ 10 - 0.5) = p(x ≥ 9.5)
Using the z formula :
Z = (x - m) / s
Z = (9.5 - 12) / 2.1908902
Z = - 1.141
p(Z > - 1.141) = 0.87307 (Z probability calculator)
p(Z > - 1.141) = 0.873
Using the binomial distribution :
P(x = x) = nCx * p^x * (1 - p)^(n-x)
p(x ≥ 10) = p(x = 10) + p(x = 11) +.... + p(x = 20)
Using calculator :
p(x ≥ 10) = 0.87247
= 0.873

result?
Do you guys know this.
Answer:
0.77
Step-by-step explanation:
You solve the inner first, then move to the outer.
Plug in x = 20 for g(x) = [tex]\frac{2x+2}{x-6}[/tex]. It should give you [tex]\frac{42}{14}[/tex], which simplifies to 3.
You then need to solve f(x) with the given value from g(x), which is 3.
Plug in x = 3 for the equation [tex]\sqrt{0.4x^2-x}[/tex], and you should get [tex]\sqrt{0.6}[/tex].
The answer is roughly 0.77.

Charlie's utility function is U(A, B) = AB, where A and B are the numbers of apples and bananas, respectively, that he consumes. When Charlie is consuming 20 apples and 80 bananas, if we put apples on the horizontal axis and bananas on the vertical axis, the slope of his indifference curve at his current consumption is:____________a. -8.b. -1/4.c. -20.d. -4.e. -1/8.
Answer:
D. -4
Step-by-step explanation:
The formula for calculating the slope of his indifference curve at his current consumption is expressed as:
M = -∆y/∆x
∆y is the change in y axis
∆x is the change in x axis
Since apples are put in the horizontal axis, ∆x = 20
Since banana are on the y axis, then ∆y = 80
Substituting the given values into the formula
M = -80/20
M = -8/2
M = -4
Hence the slope of his indifference curve at his current consumption is -4.
Option D is correct.
whats the y-intercept of y= 1/3 x-1y
Answer:
(0, 0)
Reasoning:
Y-intercept means set x to 0 and solve, therefore;
[tex]y=1/3(0) -1y[/tex]
[tex]y=0-1y[/tex]
[tex]2y=0[/tex]
[tex]y=0/2=0[/tex]
Thus, the y-intercept is (0,0)
I hope this helps you and good luck!
1. Express 0.00456 in standard form.
Answer:
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
Answer: 4.56 x 10^-3
Step-by-step explanation: To convert scientific notation to standard form, all you have to do is move the decimal to the left or the right until you get a number that is more than 1 and less than 10, then count however many spaces you had to move and add that as your exponent over 10 (if you move left, the exponent is positive, and right is negative). Basically, this just lets you know that the actual number is that many times smaller or larger than the number in your answer.
whats inequalities ?
Answer:
An equation looks something like this: 4x2=8
In an equation each value on the opposite side of the equal sign is equal unless its unsolved and u need to solve it.
In an inequality, a <, >, ≥ or ≤ separates 2 values that are unequal. < is a less than sign, > is a greater than sign and so on and so forth. An inequality gives all possible answers for an equation. For example 3x+2≤ 8 is showing us that 3x+2 is any value below or equal to 8. ≤ is a less than OR equal too sign.
in the equation 4x-5≤15 the inequality is showing us that 4x-5 is every possible value below or equal to 20. So an answer could be 19, 18, -5, 7 and basically every number below or equal to 20.

If you wish to emphasize the relation of each group to the whole, what kind of graph would be appropriate?
a.
pie chart
b.
bar graph
c.
pictograph
d.
scatter plot
Answer:
I believe that A. pie chart, is the correct answer.
Step-by-step explanation:
This is because, a pie chart is a graph that shows the percentages of different things as they relate to a whole.
A pie chart would represent this scenario best because it would have different sections for each task, as well as the amount of employees that preform each task. Together, each task would result in the whole amount of employers.
This is why this graph would be the most appropriate.
Hope this helps! :)

Find an explicit description of Nul A by listing vectors that span the null space.
A=[ 10 3 1 5 4 0 −2 ]
Answer:
The answer is "[tex]\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] , \left[\begin{array}{c}-6&2&0&1\\\end{array}\right][/tex]"
Step-by-step explanation:
Given value:
[tex]A= \left[\begin{array}{cccc}1&3&5&0\\0&1&4&-2\\\end{array}\right][/tex]
First you find the general Ax = 0 solution for the free variables.
[tex][A \ \ \ 0]= \left[\begin{array}{cccc}1&3&5&0\\0&1&4&-2\\\end{array}\right]\\\\ R_1\to R_1-3R_2\\\\= \left[\begin{array}{ccccc}1&0&-7&6&0\\0&1&4&-2&0\\\end{array}\right][/tex]
Its general solution is:
[tex]x_1 = 7x_3-6x_4,\ \ x_2=-4x_3+2x_4 \ \ with\ \ x_3, and \ x_4\ free. \ So,[/tex]
[tex]x=\left[\begin{array}{c}x_1&x_2&x_3&x_4\\\end{array}\right] = x_3\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] + x_4\left[\begin{array}{c}-6&2&0&1\\\end{array}\right][/tex]
Null A is: [tex]{\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] , \left[\begin{array}{c}-6&2&0&1\\\end{array}\right] }[/tex]

b. Choose one of the angle measures you found and justify your answer.
Answer/Step-by-step explanation:
Given:
m<3 = 83°
The following are the angle measures of the seven angles including the justification of each answer.
m<1 = m<3 (corresponding angles are congruent)
m<1 = 83° (substitution)
m<2 + m<3 = 180° (same side consecutive interior angles are supplementary)
m<2 = 180° - m<3 (Subtraction property of equality)
m<2 = 180 - 83
m<2 = 97°
m<4 + m<3 = 180° (linear pair)
m<4 = 180 - m<3 (Subtraction property of equality)
m<4 = 180 - 83 (substitution)
m<4 = 97°
m<5 = m<3 (vertical angles are congruent)
m<5 = 83°
m<6 = 180° - m<3 (linear pair theorem)
m<6 = 180 - 83°
m<6 = 97°
m<7 = m<3 (alternate interior angles are congruent)
m<7 = 83°
m<8 = m<6 (corresponding angles are congruent)
m<8 = 97°
