Find the area of the triangle.

Complete question :

A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.

Construct a confidence interval for the mean jump height of gray kangaroos.

Answer:

(271, 301)

Step-by-step explanation:

Given that:

Mean (x¯) = 286

Margin of Error = 15 inches

The confidence interval :

(Mean - Margin of Error), (mean + margin of error)

(286 - 15), (286 + 15)

(271, 301)

Hence confidence interval equals : (271, 301)

Step-by-step explanation:

Answer:

x=-1/2y , +3/4b, 7/4 this is the answer

The y-intercept is (0, 5) and the x-intercept is (2.5, 0).

In the context of a straight line in a two-dimensional plane, an intercept refers to the point(s) where the line intersects with one or both of the coordinate axes (i.e., the x-axis and the y-axis).

To find the y-intercept, we set x = 0 and solve for y:

-4(0) + 7 = 2y - 3

7 = 2y - 3

2y = 10

y = 5

Therefore, the y-intercept is (0, 5).

To find the x-intercept, we set y = 0 and solve for x:

-4x + 7 = 2(0) - 3

-4x + 7 = -3

-4x = -10

x = 2.5

Therefore, the x-intercept is (2.5, 0).

The perimeter of the given figure is 44.28 units.

Given that, from the figure length of a rectangle = 15 units, width of a rectangle = 4 units and the radius of a semicircle = 2 units.

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Here, perimeter = Perimeter of a rectangle  + Circumference of a semicircle

= 2(15+4) + 2πr/2

= 2×19 + 3.14×2

= 38 + 6.28

= 44.28 units

Therefore, the perimeter of the given figure is 44.28 units.

Answer:

-3i + (6 x 9)

Step-by-step explanation:

The zeroes of the polynomial are 1 + i, 1 – i, and 3. Then the polynomial of the lowest degree will be x³ – 5x² + 8x – 6.

A polynomial expression is an algebraic expression with variables and coefficients.

The zeroes of the polynomial will be 1 + i, 1 – i, and 3.

Then the factor of the polynomial will be (x – 1 – i), (x – 1 + i), and (x – 3).

Then the polynomial will be

(x – 1 – i)(x – 1 + i)(x – 3)

[(x – 1)² – i²](x – 3)

(x² – 2x + 2)(x – 3)

x³ – 2x² – 3x² + 2x + 6x – 6

x³ – 5x² + 8x – 6

Answer:

Step-by-step explanation:

To find the exact difference, we have to subtract the two decimal points.

1. First, we'll subtract the whole number. Then, we'll subtract the decimal number. This will make mental math easier.

a. 7 - 3 = 4

b. 8 - 2 = 6

2. Add the answers together to get your final answer.

a. = 4.6

The exact distance between the two points is 4.6. If you can't figure this strategy out, do algorithm. The simplist way to solve this is to use a calculator, which I checked my answer on. Have a nice day! :)
