Hi there!
Slope intercept form: [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope
The slope of a line is the same as its [tex]\frac{rise}{run}[/tex], or in other words, the number of units the line moves upwards over the number of units the line moves to the right.
In the graph, we can see that for every 2 units it moves right, it moves down 1 units. Therefore, our slope is [tex]-\frac{1}{2}[/tex]. This is negative since it is traveling downwards.
Plug [tex]-\frac{1}{2}[/tex] into [tex]y=mx+b[/tex] as m:
[tex]y=-\frac{1}{2} x+b[/tex]
2) Determine the y-intercept
In the graph, we can see that the line crosses the y-axis when y is equal to -3. Plug -3 into [tex]y=-\frac{1}{2} x+b[/tex] as b:
[tex]y=-\frac{1}{2} x-3[/tex]
I hope this helps!

Find the area of the smaller sector round to the nearest tenth. Need help fast!!
Answers
The area of the sector is 76. 95 m
How to determine the area of a sector
Using the formula;
Area of sector of a circle = /360° (r2)
where r is the radius of the circle
is the angle of the sector
From the diagram,
= 77°
r = 10. 7m
= 3. 142
Substitute into the formula
Area of the sector = 77/ 360° * (3. 142* 10. 7 * 10. 7)
Area of the sector = 0. 2139 * 359. 72
Area of the sector = 76. 95 m
Thus, the area of the sector is 76. 95 m

What is the surface area of the square pyramid, in square inches (Please Help)
Answers
Answer:
220.8 in.²
Step-by-step explanation:
Area of the pyramid = area of the square + 4(area of the triangle)
Area of square = s²
s = 9.2 in.
Area of the square = 9.2² = 84.64 cm²
✔️Area of the 4 triangles = 4(½*bh)
b = 9.2 in.
h = 7.4 in.
Area = 4(½*9.2*7.4) = 136.16 in²
✅Surface area = 84.64 + 136.16 = 220.8 in.²

Using the diagram, calculate the values of the unknown variables: a, b, and c.
Answers
Answer:
a = 82
b = 130
c = 118
Step-by-step explanation:
A quadrilateral is inscribed in a circle. So, it is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
a° + 98° = 180°
a° = 180° - 98°
a° = 82°
a = 82
By inscribed angle theorem:
a° = 1/2(b° + 34°)
82° * 2 = b° + 34°
164° - 34° = b°
b° = 130°
b = 130
Again by inscribed angle theorem:
76° = 1/2(c° + 34°)
76° *2 = c° + 34°
152° - 34° = c°
c° = 118°
c = 118

Each day for the next 4 days, there is a 20% chance of a thunderstorm. Use the simulation shown, where the digits 1 and 2 represent days with a thunderstorm, to estimate the probability of a thunderstorm on at least 2 of the next 4 days. Round your answer to the nearest tenth of a percent if necessary.
Answers
Answer:
It’s 6/1
Step-by-step explanation:
The estimated probability of a thunderstorm on at least 2 of the next 4 days is 6/16, or 0.375, or 37.5% (rounded to the nearest tenth of a percent).
What is probability?Probability is the measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible, and 1 indicating that the event is certain to occur.
To estimate the probability of a thunderstorm on at least 2 of the next 4 days, we can use the simulation as follows:
The outcomes with at least 2 thunderstorms are: 112, 121, 122, 211, 212, and 221.Out of the 16 possible outcomes (each day can either have a thunderstorm or not), the number of outcomes with at least 2 thunderstorms is 6.Therefore, the estimated probability of a thunderstorm on at least 2 of the next 4 days is 6/16, or 0.375, or 37.5% (rounded to the nearest tenth of a percent).Thus, this is only an estimate based on the given probability of a thunderstorm each day, and the actual probability may be different.
