The equation of the line passing through the points (- 1, -6) and (7, 2) will be → y = x - 5. The slope will be [m] = 1 and the y - intercept will be -5.
What is the slope intercept form of a straight line?The slope intercept of a straight line is -
y = mx + c
Where -
[m] is the slope of the line.
[c] is the y - intercept.
Given is a straight line passing through the points (- 1, -6) and (7, 2)
We have a straight line that passes through the coordinates as follows -
(- 1, -6)
(7, 2)
The slope of the line can be calculated using the formula -
m = (y₂ - y₁)/(x₂ - x₁)
m = (2 + 6)/(8)
m = 8/8
m = 1
The line is passing through the point (7, 2). We can write -
y = mx + c
y = x + c [m = 1]
2 = 7 + c
c = 2 - 7
c = -5
The equation of the straight line will be -
y = x - 5
Now, the slope of the line will be [m] = 1 and the y - intercept will be -5.
Therefore, the equation of the line passing through the points (- 1, -6) and (7, 2) will be → y = x - 5. The slope will be [m] = 1 and the y - intercept will be -5.

From a normally distributed population, a simple random sample of size 30 is taken. The mean of the sample is 144 and the standard deviation of the sample is 12.
Which interval is the 90% confidence interval for the population mean?
(139.7, 148.3)
142.4, 145.6)
143.3, 144.7)
140.4, 147.6)
The 90% confidence interval for the population mean is (140.4, 147.6), derived from a sample with a mean of 144 and a standard deviation of 12.
Let's break down the steps used to calculate the 90% confidence interval for the population mean:
- Sample mean ([tex]\bar{x}[/tex]): 144
- Sample standard deviation (s): 12
- Sample size (n): 30
- Critical value at 90% confidence (z): 1.645
The formula for the confidence interval is:
[tex]\[ (\bar{x} - z \cdot \frac{s}{\sqrt{n}}, \ \bar{x} + z \cdot \frac{s}{\sqrt{n}}) \][/tex]
Calculate the standard error (SE):
SE = s / sqrt(n)
SE = 12 / sqrt(30)
SE ≈ 2.188
Calculate the margin of error (ME):
ME = z * SE
ME = 1.645 * 2.188
ME ≈ 3.594
Calculate the lower limit (L):
L = [tex]\bar{x}[/tex] - ME
L = 144 - 3.594
L ≈ 140.406
Calculate the upper limit (U):
U = [tex]\bar{x}[/tex] + ME
U = 144 + 3.594
U ≈ 147.594
So, the 90% confidence interval for the population mean is approximately (140.406, 147.594), which rounds to (140.4, 147.6) when considering the appropriate level of precision. Therefore, the correct answer is (D) (140.4, 147.6).

Two circles are concentric if they have the same center.
multiply each equation by a number that produces opposite coefficient for x or y 4x +5y =7
3x-2y=-12
Final answer:
To produce opposite coefficients for x and y in the given equations, we can multiply the first equation by -3 and the second equation by 4. This allows us to eliminate the x variable and solve for y. The solution to the system of equations is x = -2 and y = 3.
Explanation:
To multiply each equation by a number that produces opposite coefficients for x or y, you need to find a number that, when multiplied by the coefficient, results in a value with the opposite sign. For example, if the coefficient is positive, you need to multiply by a negative number, and if the coefficient is negative, you need to multiply by a positive number.
In the given equations, we have:
4x + 5y = 7
3x - 2y = -12
To produce opposite coefficients for x, we can multiply the first equation by -3 and the second equation by 4. This gives us:
-12x - 15y = -21
12x - 8y = -48
Now, we can add these two new equations to eliminate the x variable:
-12x - 15y + 12x - 8y = -21 + (-48)
-23y = -69
To solve for y, we divide both sides of the equation by -23:
y = -69 / -23
y = 3
Now, we can substitute this value of y back into one of the original equations (let's use the first equation) to solve for x:
4x + 5(3) = 7
4x + 15 = 7
4x = 7 - 15
4x = -8
x = -8 / 4
x = -2
Therefore, the solution to the system of equations is x = -2 and y = 3.

A rectangular garden measures 38m by 20m, to the nearest metre. Calculate the maximum possible area of the garden.
Mark draws one card from a standard deck of 52. he receives $ 0.45 for a club, $ 0.55 for an ace and $ 0.75 for the ace of clubs. how much should he pay for one draw?
Mark should pay $0.1692 for one draw.
To calculate how much Mark should pay for one draw, we need to find the expected value, which is the sum of the products of each outcome's probability and its associated value.
Calculate the probabilities:
Probability of drawing a club: [tex]\( \frac{13}{52} = \frac{1}{4} \)[/tex]
Probability of drawing an ace: [tex]\( \frac{4}{52} = \frac{1}{13} \)[/tex]
Probability of drawing the ace of clubs: [tex]\( \frac{1}{52} \)[/tex]
Calculate the expected values:
Club: [tex]\( 0.45 \times \frac{1}{4} = 0.1125 \)[/tex]
Ace: [tex]\( 0.55 \times \frac{1}{13} = 0.0423 \)[/tex]
Ace of clubs: [tex]\( 0.75 \times \frac{1}{52} = 0.0144 \)[/tex]
Sum the expected values:
[tex]\( 0.1125 + 0.0423 + 0.0144 = 0.1692 \)[/tex]
Thus, Mark should pay $0.1692 for one draw.
