A genetic disease is found in a family that affects the immune system, lungs, heart, and kidneys. A DNA analysis of several affected and unaffected family members determines that the disease is caused by a mutation in a single gene. What type of inheritance pattern is shown in this disease?(1 point)

y = x3 – 4x2 + 2x – 5
y = x 3 – 4 x 2 + 2 x – 5
y = x3 + 4x2 – 2x – 5
y = x 3 + 4 x 2 – 2 x – 5
y = x3 + 4x2 + 2x – 5
y = x 3 + 4 x 2 + 2 x – 5
y = x4 + 4x3 – 2x2 – 5x
y = x3 + 4x2 - 2x - 5
The table shows the amount of milk that Wisconsin dairy farms produced from 1940 to 1997. Use a linear model to estimate milk production in 1990. Year Milk Produced (in billions of lbs.) 1940 7 1972 7 1997 8 (1 point) Responses 15.1 15.1 12.5 12.5 7.5 7.5 2.5
To estimate the milk production in 1990 using a linear model, we can use the given data points from 1940, 1972, and 1997.
Using the formula for the equation of a line (y = mx + b), where y is the milk production (in billions of lbs.) and x is the year, we can find the slope (m) and y-intercept (b) by using the two given data points (1940, 7) and (1997, 8).
m = (y2 - y1) / (x2 - x1)
= (8 - 7) / (1997 - 1940)
= 1 / 57
≈ 0.0175
Using the point-slope form of a line (y - y1 = m(x - x1)), we can now solve for the y-intercept (b) using the point (1940, 7).
7 - 0.0175(1940) = b
7 - 33.95 = b
b ≈ -26.95
Therefore, the equation for the linear model is:
y = 0.0175x - 26.95
To estimate the milk production in 1990, we substitute x = 1990 into the equation:
y = 0.0175(1990) - 26.95
= 34.825 - 26.95
≈ 7.875
Hence, the estimated milk production in 1990 is approximately 7.875 billion lbs.
