Answer:

Sum of the areas of two shaded regions = 100 unit² (Approx.)

Step-by-step explanation:

Given:

Radius of circle = 6 units

Angle of one unshaded area = 160'

Find:

Sum of the areas of two shaded regions

Computation:

Angle of one shaded area = 180' - 160'

Angle of one unshaded area = 20'

Sum of the areas of two shaded regions = 2[θ/360][πr²]

Sum of the areas of two shaded regions = 2[160/360][(3.14)(6)²]

Sum of the areas of two shaded regions = 2[160/360][(3.14)(36)]

Sum of the areas of two shaded regions = [0.888][113.04]

Sum of the areas of two shaded regions = 100.46

Sum of the areas of two shaded regions = 100 unit² (Approx.)

Answer:

$f(1) = {(1)}^{3} + 3 {(1)}^{2} - 9(1) + 5 \\ (x - 1) = 0 \rightarrow \: x = 1 \\\frac{{x}^{3 } + {3x}^{2} - 9x + 5}{x - 1} = {x}^{2} + 4x - 5 \\ (x + 5)(x - 1) = 0 \\ x = - 5 \: or \: x = 1 \\ \color{red}\boxed{x_{1} = 1} \\\color{yellow} \boxed {x_{2} = 1} \\ \color{green}\boxed{x_{3} = - 5}$

The answer would be C and F

If 7/12 is multiplied by a fraction less than 1 what would be the product

olga55 [171]

Answer:

<em>Examples below</em>

Step-by-step explanation:

We have the fraction

$\frac{7}{12}$

It's required to multiply it by any fraction less than 1. Let's select the following fractions. All of them are less than 1 because the numerator is less than the denominator:

$\frac{1}{7}$

$\frac{4}{5}$

$\frac{6}{35}$

The required products are:

$\frac{7}{12}\cdot \frac{1}{7}=\frac{7}{7*12}=\frac{1}{12}$

$\frac{7}{12}\cdot \frac{4}{5}=\frac{4*7}{12*5}=\frac{7}{15}$

$\frac{7}{12}\cdot \frac{6}{35}=\frac{6*7}{12*35}=\frac{1}{10}$

The answer choices below represent different hypothesis tests. Which of the choices are one-tailed tests? Select all correct ans

Lapatulllka [165]

Answer:

H0:p=0.46, Ha:p<0.46

H0:p=0.39, Ha:p<0.39

Step-by-step explanation:

A one tailed test occurs in such a way that the value/results gotten is one sided and can either be lesser or greater than the particular given value but cannot be both.

Thus, in this case a one sided test includes

H0:p=0.46, Ha:p<0.46

H0:p=0.39, Ha:p<0.39
