YES!

Step-by-step explanation:

if its less than 1, then ur reducing

ex. = 1 x 0.5 = 0.5

If its greater than 1, then ur increasing

Answer:

Gavin is correct

Step-by-step explanation:

Since the problem is using a denominator of 10, I will convert 1 (1 representing the full length of the board before being sawed) to a fraction over 10

1 = 10/10

Subtract everything Gavin sawed off from the board

10/10 - 2/10 - 5/10 - 1/10

Only subtract the numerators; the denominators will stay the same

8/10 - 5/10 - 1/10

3/10 - 1/10

2/10

Gavin says he has 2/10 of the board left to use

Since we concluded we still have 2/10, he is correct

Answer:

Step-by-step explanation:

By applying sine rule in the given triangle,

cos(25°) = [tex]\frac{\text{AC}}{AB}[/tex]

cos(25°) = [tex]\frac{b}{400}[/tex]

b = 400[cos(25°)]

b = 362.52

b = 363 ft

By applying sine rule in the given triangle,

sin(25°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(25°) = [tex]\frac{a}{400}[/tex]

a = 400[sin(25°)]

a = 169.05

a = 169 ft

m∠A + m∠B + m∠C = 180°

25° + m∠B + 90° = 180°

m∠B = 180° - 115°

m∠B = 65°

Answer:

  G.  84.5 cm

Step-by-step explanation:

Assuming the lateral area is 6760π cm², we can find the height from ...

  A = 2πrh

  r = A/(2πh) = (6760π cm²)/(2π·40 cm) 6760/80 cm = 84.5 cm

The radius of the can is 84.5 cm.

Answer:

1.2×10⁸ is greater than 6×10³ by a factor of 2×10⁴, or 20000.

Step-by-step explanation:

You can solve this simply by dividing the first one by the second one:

[tex]\frac{1.2\times 10^8}{6\times 10^3} \\\\= \frac{1.2}{6} \times \frac{10^8}{10^3} \\\\= \frac{12}{6} \times \frac{10^7}{10^3} \\\\= 2.0 \times 10^4 \\\\[/tex]

Answer:

Squared differences between actual and predicted y

Step-by-step explanation:

The least squares regression method used in predictive modeling for linear regression models produces a best fit line which will minimize the square of the mean difference between the actual and projected or predicted values of the dependent, y variable. Hence, the when the sum of the squared value of the difference between the actual and predicted values (residual) are taken, the fit which gives the minimum sum of squared value is the best fit line upon which the estimated regression equation is based.

The true statement is that the estimated regression equation by least squares method minimizes the sum of the (c) Squared differences between actual and predicted y.

In regression, the least square method is used to estimate quantities.

This is done in order to minimize the sum of the squares of the differences between the observed values and the estimated values.

In this case, the observed value and the estimated values represent the actual and predicted y

Hence, the true statement is that the estimated regression equation by least squares method minimizes the sum of the (c)
