Multiply both sides by 2.3, ( tan 6° x 2.3 = f )
Regroup terms, 2.3 tan 6 = f.
F = 2.3 tan 6°
So the answer is tan 6 = tan 6 I think
Answer:
-9 1/4
Step-by-step explanation:
Answer:
z = 3
Step-by-step explanation:
Δ UWV and Δ UWX are similar triangles , thus corresponding angles are congruent , that is
∠ UWV = ∠ UWX , substitute values
9z - 24 = z ( subtract z from both sides )
8z - 24 = 0 ( add 24 to both sides )
8z = 24 ( divide both sides by 8 )
z = 3
Answer:
B. Sample mean used to estimate a population mean.
C. Sample variance used to estimate a population variance.
D. Sample proportion used to estimate a population proportion.
Step-by-step explanation:
This is because the mean of the sampling distribution of the mean tends to target the population mean. Also, the mean of the sampling distribution of the variance tends to target the population variance.
This means that the sample mean and variance tend to target the population mean and variance, respectively, instead of systematically tending to underestimate or overestimate that value. This is why sample means and variances are good estimators of population means and variances, respectively. This is also true for proportions but not true for medians, ranges and standard deviations.
Answer:
g⁻¹(x) = 2 + ∛x
Step-by-step explanation:
g(x) = (x - 2)³ Rename g(x) as y
y = (x - 2)³
Solve for x :
y = (x - 2)³ Multiply each side by 3
∛y = x - 2 Add 2 to each side
∛y + 2 = x
x = ∛y + 2 Switch x and y
y = ∛x + 2 Rename y as g inverse
g⁻¹(x) = 2 + ∛x
See the graphs of g(x) and g⁻¹(x) below.
g(x) is the red line. g⁻¹(x) is the blue line.
Each graph reflects the other about the dashed line representing the function y = x.
