Given:
Triangle base: 8 yards
Triangle height: 3 yards

The area of a triangle is solved using this formula:

Area = (height * base) / 2

Using the given data:

Area of a triangle = (3 yards * 8 yards)/2
Area of a triangle = 24 square yards / 2
Area of a triangle = 12 square yards.

The area of the given triangle is 12 square yards.

The equation for area of a triangle is given below.

Area of Triangle = 0.5*Base*Height

Since we are given that the base is 8 yards and height is 3 yards...

Area of Triangle = 0.5 * 8 yards * 3 yards = 12 yards^2

Answer:

y = -x - 6

Step-by-step explanation:

Parallel lines have same slope

y = -x + 9 {y = mx + c}

m = -1

(x₁, y₁) = (7 , -13)

Equation: y - y₁ = m(x -x₁)

y - [-13] = -1(x -7)

y+ 13 = -x + 7

y = - x + 7 - 13

y = -x - 6

This claim is to be investigated at .01 levels. “Forty percent or more of those persons who retired from an industrial job befor

Degger [83]

According to the described situation, we have that:

The null hypothesis is $H_0: p < 0.4$

The decision rule is:

z < 2.327: Do not reject the null hypothesis.

z > 2.327: Reject the null hypothesis.

The value of the test statistic is of z = -0.866.

<h3>What is the null hypothesis?</h3>

The claim is:

"Forty percent or more of those persons who retired from an industrial job before the age of 60 would return to work if a suitable job were available"

At the null hypothesis, we consider that the claim is false, that is, the proportion is of less than 40%, hence:

$H_0: p < 0.4$

<h3>What is the decision rule?</h3>

We have a right-tailed test, as we are testing if a proportion is less/greater than a value. Since we are working with a proportion, the z-distribution is used.

Using a z-distribution calculator, the critical value for a right-tailed test with a significance level of 0.01 is of z = 2.327, hence, the decision rule is:
