Answers
Answer:
33/ 338
Step-by-step explanation:
Red = 6
Blue = 9
P.Red = 6/26 = 3/13
P.Green = 11/26
P. Both in turns = 3/13 * 11/26

Write an equation for the nth term of the arithmetic sequence. Then find a30.
11, 10, 9, 8,
Answers
Answer:
a₃₀ = - 18
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = a₂ - a₁ = 10 - 11 = - 1, then
[tex]a_{n}[/tex] = 11 - (n - 1) = 11 - n + 1 = 12 - n , thus
a₃₀ = 12 - 30 = - 18

Answer: Choice A. y + 5 = -2(x + 2)
================================================
Explanation:
Let's solve the given equation for y so we can find the slope.
3x - 6y = 2
3x = 2+6y
3x-2 = 6y
6y = 3x-2
y = (3x-2)/6
y = (3x/6) - (2/6)
y = (1/2)x - 1/3
The last equation is in y = mx+b form. We see that m = 1/2 is the slope.
Apply the negative reciprocal to go from 1/2 to -2/1 or just -2.
The original slope is 1/2, and the perpendicular slope is -2.
Rule: multiplying any two perpendicular slopes leads to -1 where neither line can be vertical.
Let's plug in m = -2, x1 = -2 and y1 = -5 into point slope form
y - y1 = m(x - x1)
y - (-5) = -2(x - (-2))
y + 5 = -2(x + 2)

What is cybersickness ?Similar to motion sickness, cybersickness is a mix of sensations that develops when there is no actual physical movement. The three types of symptoms are nausea, oculomotor problems, and general disorientation.
Eye strain, weariness, and headaches are examples of oculomotor symptoms that result from overworking the nerve that regulates eye movement.
The symptoms of disorientation can include vertigo and dizziness. Additionally, numerous cybersickness symptoms, including trouble focusing and fuzzy vision, cross over into different categories.
As per the given results, there are two 1s and two 0s in the number lines of the trial. Hence, total response of "yes" is 4.

rohan wants a field in the shape of trapezium . its side along the pond is parallel to and double the side along the road .Area of the field is 10200sqm.What is the length of the side along the river?
plss answer, will mark u the brainlliast
Answers
Answer:
The length of side along the river is 68 m
Step-by-step explanation:
Area of trapezium = 10200 m²
Length of side along the road (a) = x
Length of side along the river (b) = 2x
Height = 200 m
We need to find Length of side along the river.
The formula used is: [tex]Area\: of\: trapezium=\frac{a+b}{2}\times h[/tex]
Putting values and finding length:
[tex]Area\: of\: trapezium=\frac{a+b}{2}\times h\\10200=\frac{2x+x}{2}\times 200\\10200=2x+2\times 100\\\frac{10200}{100} =2x+2\\102=3x\\x=\frac{102}{3}\\x=34[/tex]
So, Value of x = 34
Length of side along the road (a) = x = 34
Length of side along the river (b) = 2x = 2(34) = 68
So, the length of side along the river is 68 m

Alexander's new glasses cost would be the amount of $108.55 which is the correct answer would be an option (B).
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have been given that Alexander's new glasses normally cost $167 at a retailer, but he only paid 65% of the retail cost.
To determine the amount his new glasses cost
We have to calculate 65% of $167 which is the retail cost.
As per the given information, the solution would be:
⇒ 65% of $167
⇒ (65/100)(167)
⇒ (0.65)(167)
⇒ 108.55
Therefore, his new glasses cost would be the amount of $108.55.

Answer:
y = 4x - 4
Step-by-step explanation:
to write a linear equation you need to know 2 components: slope and y-intercept
find slope by selecting 2 points, for example, (1,0) and (2,4)
slope ('m') = difference of y-values 4 - 0 = 4
difference of x-values 2 - 1 1
to find y-intercept ('b'), plug values into the slope-intercept form of a line, which is:
y = mx + b
you need a point and the slope of 4/1; can use any point
we'll use (2,4) where x =2 and y=4 and, again, m = 4
4 = 2(4) + b
4 = 8 + b
-4 = b
Cole and Jamie are raising money for the annual Walk for Hunger in their city. They each have a goal to raise $250. So far, Cole has raised $150 and Jamie has raised $180.
Answers
Answer:
a) For Cole = 60%
b) For Jamie = 72 %
Step-by-step explanation:
Cole and Jamie are raising money for the annual Walk for Hunger in their city. They each have a goal to raise $250. So far, Cole has raised $150 and Jamie has raised $180.
What percent of their goal did each boy raise so far?
a) Percent of Cole's goal
= Amount raised by Cole/ Total amount × 100
= $150/$250 × 100
= 60%
b) Percent of Jamie's goal
Amount raised by Jamie / Total amount × 100
= $180/$250 × 100
= 72%

Answer:
a) profit has a typical curve: negative at low volume, and again at very high volume.
b) $239,407
Step-by-step explanation:
a) The graph is negative below x=1.58, so the break-even point is 158 toys sold. The profit declines steeply above 533 toys sold, to again go negative for 774 toys sold. This sort of curve seems fairly typical.

Which statement comparing the modes to the ranges is true?
Answers
Answer: A. The modes differ by 40 and the ranges differ by 40.
Step-by-step explanation:
The required, modes differ by 40 and the ranges differ by 40. Option A is correct.
To compare the modes and ranges of the given data, let's first find the modes and ranges.
Last Summer:
140, 220, 190, 180, 190
This Summer:
150, 170, 150, 190, 180
The mode is the value that appears most frequently in a dataset, while the range is the difference between the maximum and minimum values in a dataset.
The modes are as follows:
Last summer: The mode is 190 since it appears twice, more frequently than any other value.
This summer: The mode is 150 since it appears twice, more frequently than any other value.
The ranges are as follows:
Last summer: The range is 220 - 140 = 80.
This summer: The range is 190 - 150 = 40.
Now, let's compare the modes to the ranges:
Statement: The modes differ by 40 and the ranges differ by 40. Since the modes differ by 40 and the ranges differ by 40, the statement is true.
Therefore, the correct statement is:
A. The modes differ by 40 and the ranges differ by 40.
