Suppose you perform an ANOVA on 18 subjects divided evenly into three groups according to age. Reading speed is measured and ave

raged for each of the three groups. The reading speed for the Young Group is 10; for the Middle Group, 12; and for the Older Group, 13. Your F-obtained is 9.15. This is a significant F-obtained. Which of the following is the correct way to report this finding? A. The Older Group reads significantly faster than any other group. B. The Young Group reads significantly faster than any other group. C. There is a significant difference between the Older Group and the Middle Group. D. There is a significant difference among the reading speeds somewhere.

The slope is 2. (m=2).

Step-by-step explanation:

y+5=2x+2

y+5-5=2x+2-5

y=2x-3

Equation is y=2x-3.

y=y-intercept

x=slope

Hence, the slope is 2.

Mitch has a swimming pool in his backyard. The rectangular swimming pool has a volume of 243 m cubed. The length of the pool is
Maksim231197 [3]

Answer:

81m^{3}

Step-by-step explanation:

Since the question states that the only difference would be the length of the neighbor's pool then this is basically a ratio problem. Therefore, since the question provides 3 values and one variable we can solve this using the Rule of Three which takes the diagonal values multiplies them together, and divides by the last sole value to get calculate the variable like so...

243 m^{3} volume  <=====>  9 m length

x m^{3} volume  <=====>  3 m length

(3* 243) / 9 = 81m^{3}

Therefore, the volume of the neighbors pool will be 81m^{3}

What is the area of rectangle ABCD, if points A, B, C, and D have the following coordinates?
slega [8]

Answer:

The area of the rectangle ABCD is \frac{2}{5} square units.

Step-by-step explanation:

From statement we have that rectangle ABCD is formed by the following points: A(x,y) = (2, 5), B(x,y) = \left(\frac{8}{3}, 5 \right), C(x,y) = \left(\frac{8}{3}, \frac{28}{5}  \right), D(x,y) = \left(2, \frac{28}{5} \right). First, we calculate the length of each side by the Pythagorean Theorem:

AB = \sqrt{\left(\frac{8}{3}-2 \right)^{2}+ (5-5)^{2}}

AB = \frac{2}{3}

BC = \sqrt{\left(\frac{8}{3}-\frac{8}{3}\right)^{2}+\left(\frac{28}{5}-5\right)^{2} }

BC = \frac{3}{5}

CD = \sqrt{\left(2-\frac{8}{3} \right)^{2}+\left(\frac{28}{5}-\frac{28}{5}  \right)^{2}}

CD = \frac{2}{3}

DA = \sqrt{\left(2-2\right)^{2}+\left(5-\frac{28}{5} \right)^{2}}

BC = \frac{3}{5}

Which satisfies all minimum characteristics for a rectangle. The area of the rectangle ABCD is the product of its base and its height, that is:

A = \left(\frac{2}{3}\right)\cdot \left(\frac{3}{5} \right)

A = \frac{2}{5}

The area of the rectangle ABCD is \frac{2}{5} square units.
