Answer:

The correct answers are:

7) 2 to 5

8) the product of the means is equal to the product of the extremes (D)

Step-by-step explanation:

7) Number of tbsp of sugar = 4

Number of tbsp of baking powder = 10

∴ ratio of sugar to baking powder = 4 : 10

simplifying further by dividing through by 2

4 : 10 = 2 : 5

∴ ratio of sugar to baking powder = 2 to 5

8) A proportion is a statement that equates two rates or ratios.

For example:

\frac{a}{b} = \frac{c}{d}

In this equation, the first and the fourth terms (a and d) are called <em>extremes</em><em>, </em>while the second and third terms are called means.

Therefore, one rule of proportions is that the product of the extremes must equal the product of the means. This means that:

a × d (extremes) = b × c (means)

Answer:

Null hypothesis: There is no relationship between direction of the ball and if it resulted in a hit or an out.

Step-by-step explanation:

In this case, the experiment conducted is to determine whether there is any relationship between the direction of the ball and if it resulted in a hit or an out.

A random sample of 300 balls hit into play in college baseball games is taken. For each ball hit into play, it is recorded whether the ball was hit to the left, center, or right of the field, and whether the ball resulted in a hit or an out.

The regression analysis would be used to determine whether there is any relationship between direction of the ball and if it resulted in a hit or an out.

The hypothesis for the regression analysis is defined as follows:

<em>H</em>₀: There is no relationship between direction of the ball and if it resulted in a hit or an out.

<em>H</em>ₐ: There is a significant relationship between direction of the ball and if it resulted in a hit or an out.

Solve for e. (-7) = e/3 + 14
raketka [301]
<span>(-7) = e/3 + 14

Subtract 14 on both sides

-7 - 14 = e/3 + 14 - 14

-21 = e/3 

Multiply by 3 on both sides

-21 * 3 = e/3 * 3

-63 = e</span>

pashok25 [27]

<span>Owls are found in many different habitats, such as deserts, forests, prairies and even the Arctic tundra. They nest in trees, in holes in the ground, in barns, and in caves. And while many other birds migrate to warmer places during the winter, most owls do not. They live in the same place all year round.</span>
