Step-by-step explanation:
Since the relationship is linear then the slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, - 1) and (x₂, y₂ ) = (10, 1) ← 2 ordered pairs from the table
m = [tex]\frac{1+1}{10-5}[/tex] = [tex]\frac{2}{5}[/tex]
The point (0, - 3 ) indicates c = - 3 , then
y = [tex]\frac{2}{5}[/tex] x - 3 ( multiply through by 5 to clear the fraction )
5y = 2x - 15 ( subtract 2x from both sides )
5y - 2x = - 15 → B

Exterior angle is same as the sum of non-adjacent interior angles.#18
m∠3 = 43° + 22° = 65°#20
123° = 90° + m∠4 ⇒m∠4 = 123° - 90° = 33°18) Solution
By using exterior angle is same as the sum of non adjacent interior angles.
→ m<3 = 43° +22°
→ 65°
20) Solution
By using exterior angle is same as the sum of non adjacent interior angles.
→ 123° = 90° + m<4
→ m<4 = 123°-90°
→ 33°

The answer is A. 6.4 and 5.6 and D. 39 and 27.
Step-by-step explanation:
A. 6.4 and 5.6 = 1.6 and 1.4
6.4 / 1.6 = 4
1.4 * 4 = 5.6
So A is correct.
D. 39 and 27 = 13 and 9
39 / 13 = 3
9 * 3 = 27
So D is correct.

Consultant plans a survey to determine what % of the patients in a particular hospital were satisfied with the care they received after a major treatment. How many such patients should be surveyed so the margin of error for a 90% confidence interval is within .05? Suppose it is known from a past survey that such a % may be about 80%.
Answers
Solution:
Required margin of error = 0.05
Estimated population proportion p = 0.8
Significance level = 0.10
The [tex]\text{provided estimate population proportion}[/tex] p is 0.8
The significance level, α = 0.1 is [tex]z_c=1.645[/tex], which is obtained by looking into a standard normal probability table.
The number of patients surveyed to estimate the population proportion p within the required margin of error :
[tex]$n \geq p(1-p)\left(\frac{z_c}{E}\right)^2$[/tex]
[tex]$=0.8\times (1-0.8)\left(\frac{1.64}{0.05}\right)^2$[/tex]
= 173.15
Therefore, the number of patients surveyed to satisfy the condition is n ≥ 173.15 and it must be an integer number.
Thus we conclude that the number of patients surveyed so the margin of error of 90% confidence interval is within 0.05 are n= 174.
(a) The diagram shows four angles around a point
1. Write down an equation in x and y
2. Simplify your equation
3.Find y when x=65°
Answers
Answer:
Step-by-step explanation:
The degrees around a point = 360, so
1. x + 95 + 3y + 80 = 360 so
2. x + 3y = 185
3. 65 + 3y = 185 and
3y = 120 so
y = 40
Answer:
y=40
Step-by-step explanation:
sum of all 3 angles : 240
3y+240=360
3y=360-240=120
y=3÷120
y=40

Answers
Answer:
9
Step-by-step explanation:
A sandwich shop advertises 108 combinations (one meat + one cheese).
There are 3 types of bread and 4 cheeses.
Number of combinations:
3 × 4 = 12 combinations
Therefore, the number of different meats that they do offer is calculated as:
= 108 combinations/ Number of combinations for meat and cheese
108 combinations/12 combinations
= 9 different meats

We are given the equation below:
[tex] \large{ {p}^{2} = \frac{9}{36} }[/tex]
Use the property below:
[tex] \large \boxed{ {x}^{2} = \frac{a}{b} \longrightarrow x = \pm \frac{ \sqrt{a} }{ \sqrt{b} } \: \: (a \geqslant 0 \: \: and \: \: b > 0)}[/tex]
From the equation:
[tex] \large{p = \pm \frac{ \sqrt{9} }{ \sqrt{36} } } \\ \large{p = \pm \frac{3}{6} \longrightarrow p = \pm \frac{1}{2} }[/tex]
Hence the answer is p = ± 1/2.

What is the equation of a circle with center (7, 2) and radius 2?
Answers
Answer:
(x - 7)² + (y - 2)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (7, 2 ) and r = 2 , then
(x - 7)² + (y - 2)² = 2² , that is
(x - 7)² + (y - 2)² = 4 ← equation of circle
