Step-by-step explanation:

the table was filled correctly already by somebody yesterday.

the important thing to remember is that an arc angle is always measured at the center point of the circle. that is the difference to angles between the intersecting lines of arc segments.

it would be really important that you start doing these things yourself. this hands-on experience of these (really basic) questions is designed to help you get a feeling how these things work together, which makes later topics much easier for you.

please tell me what you don't understand here. you only need to apply common sense. no magic voodoo math formulas or strategies.

FAR = 100° FR = 140° VO = 60° FR+VO = 200°

FAV = 80° FV = 60° RO = 100° FV+RO = 160°

OAV = 100° VO = 60° FR = 140° VO+FR = 200°

OAR = 80° RO = 100° FV = 60° RO+FV = 160°

how did we get the measures of the intercepted arcs ? by counting the 20° segments on the arc. the full circle arc represents 360°. always, for every circle. one time around is one time around and therefore 360°, no matter the size of the circle.

when you stand directly on the south pole of the Earth for 24 hours, you will have rotated the full 360° in that time (one rotation per day). if you stand on the equator for 24 hours, the Earth has taken you on one spin of the full 360°. the difference is the absolute arc length and the necessary speed at which we cover the distance of a full arc length.

every 250 million years our whole sogar system rotates once (by the full 360°) around the center of our galaxy.

the degrees have nothing to do with radius, diameter, area, ... of a circle. only with the relative parts of the circumference. when the minute arm of a clock moved for 15 minutes, then it went 90° around the clock's face. after 60 minutes it went the full 360°, and the cycle starts anew.

so, minutes on a clock or hours of the day are just another way of counting degrees around a circle.

what have we noticed with the sum of the measures of the intercepted arcs ?

many things.

e.g.

they are exactly twice as large as the line angles. 100 to 200. 80 to 160.

the sum of 2 pairs of opposing arc angles is always 360°.

...

so, how will we get the line angles based on the sum of the angles of the intersected arcs ?

we cut the sum of the intersected arc angles in half. 200 to 100. 160 to 80.

On a distance-time graph, a constant slope indicates a constant speed or velocity. The slope of a line on a distance-time graph represents the rate of change of distance with respect to time.

If the slope remains constant, it means that the distance covered per unit of time is consistent throughout the entire duration represented by the graph.

When the slope is constant, it implies that the object or subject being represented is moving at a steady pace. This means that for each unit of time, an equal amount of distance is covered. For example, if the slope of the graph is 2, it indicates that for every unit of time (e.g., 1 second), the object or subject is covering 2 units of distance (e.g., 2 meters).

A constant slope can also suggest uniform motion, where the speed remains constant without any acceleration or deceleration. In this case, the object is moving at a steady rate, maintaining the same speed throughout the given time interval.

It's important to note that the slope's magnitude doesn't provide information about the actual speed; it only indicates that the speed remains constant. The actual speed can be determined by examining the scale and units on the graph.

In summary, a constant slope on a distance-time graph indicates that the object or subject is moving at a constant speed or velocity, covering the same amount of distance per unit of time, suggesting either uniform motion or a steady pace.

Resulting function is y = -(1/5)e⁴ˣ - 4, which can be written in the form y = \(ce^{ax}\) + b as y = (-1/5)e⁴ˣ - 4.

To transform the given function y = e⁴ˣ according to the given conditions, we will perform the following steps:

1. Vertically compress With a factor of 5:
y = (1/5)e⁴ˣ

2. Reflect across the x-axis:
y = -(1/5)e⁴ˣ

3. Shift down 4 units:
y = -(1/5)e⁴ˣ - 4

So the resulting function is y = -(1/5)e⁴ˣ - 4, which can be written in the form y = ceᵃˣ + b as y = (-1/5)e⁴ˣ - 4.

Answer:

Step-by-step explanation:

To determine how long it takes for Martin and Gordon to complete the maintenance when working together, we can use the concept of their combined work rates.

Martin takes 4 hours to complete the work, so his work rate is 1/4 of the job per hour (1 job / 4 hours = 1/4 job/hour).

Similarly, Gordon takes 2 hours to complete the work, so his work rate is 1/2 of the job per hour (1 job / 2 hours = 1/2 job/hour).

When they work together, their work rates are additive. Therefore, the combined work rate is:

Combined work rate = Martin's work rate + Gordon's work rate

Combined work rate = 1/4 job/hour + 1/2 job/hour

Combined work rate = 3/4 job/hour

To find the time it takes for them to complete the maintenance when working together, we can use the formula:

Time = 1 / Combined work rate

Time = 1 / (3/4 job/hour)

Time = 4/3 hours

Therefore, the correct option is:

Four thirds

The maintenance takes 4/3 hours (or 1 hour and 20 minutes) when Martin and Gordon work together.

Answer:

\(\huge\boxed{\sf n = 11}\)

Step-by-step explanation:

Total trees = 1260 trees

Maple trees:

\(\displaystyle = \frac{1}{5} \ of \ total \ trees\\\\= \frac{1}{5} \times \ 1260\\\\= \frac{1260}{5} \\\\= 252 \ maple \ trees\)

Beech trees:

Given that:

Maple trees = 3 × beech trees

=> There are 252 maple trees.

252 = 3 × beech trees

Divide 3 to both sides

252 / 3 = beech trees

84 trees = beech trees

\(\boxed{\sf beech \ trees = 84 \ trees\\}\)

Oak trees:

It is said that all other trees are oak trees.

So, oak trees will be:

= total trees - maple trees - beech trees

= 1260 - 252 - 84

= 924 trees

The ratio of oak trees to beech trees:

= 924 : 84

Divide 84 to both sides

= 11 : 1

The question says:

number of oak : number of beech = n : 1

So, from the answer, it is clear that:

n = 11

The sample proportion is 0.530 and the z-critical value is 2.58 and the confidence interval at 99% is ( 0.503, 0.556 ).

Given that,

Because watching TV via digital streaming is becoming more and more common, tv advertising companies are having a harder time connecting with viewers. 53% of the 2343 American adults surveyed by the Harris Poll on November 13, 2012, claimed they had viewed digitally streamed television content on at least one device.

We have to find what is the sample proportion? firstly, the z-critical value is ? What is the confidence interval at 99%?

We know that,

n = 2343

Point estimate = sample proportion = \(\hat p\) = 0.530

1 - \(\hat p\) = 1 -0.530 = 0.470

At 99% confidence level

α = 1-0.99% =1-0.99 =0.01

α /2 =0.01/ 2= 0.005

Z(α /2) = Z0.005 = 2.576

Z (α/2) = 2.576 = 2.58

Margin of error = E = Z (α/2) × √((\(\hat p\) × (1 - \(\hat p\) )) / n)

=2.576 × (√(0.530×(0.470) /2343 )

= 0.027

A 99% confidence interval for population proportion p is ,

\(\hat p\)- E < p < \(\hat p\) + E

0.530 -0.027 < p < 0.530 +0.027

0.503 < p < 0.556

( 0.503, 0.556 )

Therefore, The sample proportion is 0.530 and the z-critical value is 2.58 and the confidence interval at 99% is ( 0.503, 0.556 ).

x + y = 2

Substitute y = x + 8 in the second equation:

x + x + 8 = 2

2x + 8 = 2

2x = -6

x = -3

Now plug this into the first equation

y = -3 + 8 = 5.
