Answer:
[tex]w = - 0.5[/tex]
Step-by-step explanation:
Given
[tex]w = 0.3d - 0.5[/tex] [The correct equation]
Required
Find and interpret the 0
To do this, we set [tex]d = 0[/tex]
Substitute 0 for d in [tex]w = 0.3d - 0.5[/tex]
[tex]w = 0.3 * 0 - 0.5[/tex]
[tex]w = 0 - 0.5[/tex]
[tex]w = - 0.5[/tex]

There are 9 red marbles and 4 blue marbles in a bag? What is the ratio blue marbles to all marbles in the bag? Ratio of blue marbles to red marbles
Answer:
4/13
Step-by-step explanation:
There are 9+4=13 marbles in total.
So, the ratio is 4/13.
The ratio of blue marble to all marbles is 4: 13 while blue marbles to red marbles are 4: 9.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
Number of blue marbles = 4
Number of red marbles = 9
Total number of marbles = 9 + 4 = 13
The ratio of blue to total marble = 4/13
The ratio of blue to red = 4/9
Hence "The ratio of blue marble to all marbles is 4: 13 while blue marbles to red marbles are 4: 9.".

Use an exponential expression to calculate the area covered by purple loosestrife 7 years from now. Is this a valid
prediction? What does this result tell you about the constraints on the exponential model?
The area of the wetland that will be covered in purple loosestrife 7 years from now is modeled by this expression.
500(1.2)^7
After evaluating the expression, the model predicts that approximately 1,792 acres of the wetland will be covered in purple loosestrife 7 years from now. This is not a valid prediction because the total area of the wetland is only 1,240 acres. So a constraint on the model is that the value of the expression 500(1.2)^t must be less than or equal to 1,240.
Answer: 500(1.2)^7

A 50 ohm load dissipates 100 W of power. How much voltage is across the load?
Answer:
5000 volts
Step-by-step explanation:
we know v×IR so voltage equals current*resistance so 50*100 so 5000
9514 1404 393
Answer:
about 70.7 V
Step-by-step explanation:
The relation between power and voltage and resistance in a resistive circuit is ...
P = V^2/R
so ...
V = √(PR)
V = √(100·50) = √5000
V ≈ 70.7 . . . . volts

Answer:
B, 5/4s
Step-by-step explanation:
If something increases by 1/4, it means that it is the original number + 1/4 of it.
Ex: x + 1/4x = 5/4x
So if we substitute s for x, the answer must be 5/4s, or B
Bernard designs motorized bicycles at Smart Gear Technologies. His total earnings are
$54,000 this year. Bernard pays $201 in payroll taxes for every $1,000 he earns.
What is Bernard's net income for this year?
Answer: $43146
Step-by-step explanation:
So his total earning is $54,000. He has to pay $201 for every $1,000 he earns. So 54,000/1,000= 54. So now he has to pay 54*201=10854, 54000-10854=43146. His net income for this year is $43146.

It is 11.
no one answered it last time :(
Answer:
Step-by-step explanation:
The perimeter is 28".
The total length of three sides of the square = 28-5-5 = 18", so the side length of the square is 18/3 = 6".
The area of the triangle is ½(6)(4) = 12 square inches.
The area of the square is 6² = 36 square inches.
Total area = 12+36 = 48 square inches.
Which of the following is NOT a common characteristic of a binomial distribution?
Question 28 options:
There are exactly two possible outcomes: success and failure.
The probability of success is the same in all trials.
There are a fixed number of observations.
You should perform x trials until you observe a success.
Each trial is independent
Answer:
You should perform x trials until you observe a success.
Step-by-step explanation:
By process of elimination:
A binomial experiment is a statistical experiment that must meet certain requirements:
Each outcome is either a success (P) or a failure (Q).
All trials are independent.
There are a fixed number of "n" trials.
The probability of success, p, is the same for each trial.
The probability of success, p, is the same for each trial.
You should perform x trials until you observe a success.
We have given that,
There are exactly two possible outcomes success and failure.
We have to determine the following is NOT a common characteristic of a binomial distribution.
By process of elimination
A binomial experiment is a statistical experiment that must meet certain requirements
Each outcome is either a success (P) or a failure (Q).
What is the independent probability?
Independence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes.
All trials are independent.
There are a fixed number of n trials.
The probability of success, p, is the same for each trial.

The perimeter of a rectangle is 54 inches.
Its length is 15 inches.
What is the width (w)?
Answer:
12
Step-by-step explanation:
if the perimeter is 54, and the length is 15,
first double the length (to include both sides of the rectangle):
15(2)=30
subtract that by 54:
54-30=24
to find the width we would divide 24 by 2, because 24 represents both sides of the rectangle:
24/2=12
the width is 12.

Step-by-step explanation:
The coordinates of A = (2,9)
The coordinates of B = (7,4)
Let M (x,y) be the mid point of A and B.
[tex]M(x,y)=(\dfrac{x_1+x_2}{2}),(\dfrac{y_1+y_2}{2})\\\\=\dfrac{2+7}{2}, \dfrac{9+4}{2}\\\\=(\dfrac{9}{2}, \dfrac{13}{2})[/tex]

Answer:
The answer is below
Step-by-step explanation:
A rectangle is a quadrilateral (four sides) with two pairs of equal opposite and parallel sides. All the four angles in a rectangle are equal to 90° (right angle). The diagonals of a rectangle are equal and bisect each other.
The area of a rectangle = length * breadth
a) Area = length * breadth = 8 cm * 3 cm = 24 cm²
b) Area = length * breadth = 5.2 cm * 7.7 cm = 40.04 cm²
