If a dart was thrown randomly at the dart board shown below, what is the probability that it would land between the outer circle

Mademuasel [1]

Answer: B) 67%

<u>Step-by-step explanation:</u>

Find the Area of the Bullseye and Middle ring

A = π r²

A (inside) = π(8)² = 64π

Find the Area of the entire Target

A (target) = π (14)² = 196π

Find the Area of the Outer ring

A (outer ring) = A (target) - A(inside)

= 196 π - 64π

= 132 π

The last step is to find the probability of landing on the outer ring:

$P=\dfrac{success (area\ of\ outer\ ring)}{total\ possible\ outcomes(area\ of\ target)}=\dfrac{132\pi}{196\pi}=0.673=\large\boxed{67\%}$

Jamie is walking her neighbors’ dog while they are away. She is keeping track of the total number of blocks she walks over time.

Bumek [7]

Answer:

C. Yes, because the ratios are equivalent between each pair of values.

Step-by-step explanation:

A relationship between two quantities is proportional if the ratio of the two quantities are the same for all the given possible pairs of values.

In the table given, the ratio of block to mins in the first given pair of values is 3/6 = 3/6 = ½.

In the second given pair, it is 7 to 14 = 7/14 = ½. The same ratio is gotten for the others as well.

Therefore, the table represents a proportional relationship.

The answer is: "C. Yes, because the ratios are equivalent between each pair of values."

Write the form of the partial fraction decomposition of the function. Do not determine the numerical values of the coefficients.

Gnoma [55]

Answer:

$\frac{A}{(x-1)} + \frac{B}{(x-9)}$

Step-by-step explanation:

Given the expression $\dfrac{1}{(x-1)(x-9)}$ , we are to write the expression as a partial fraction. Writing as a partial fraction means rewriting the expression a s a sum of two or more expression.

Before we will do this we will need to check the nature of the function at the denominator whether it is linear, quadratic or a repeated function. According to the question, the denominator at the denominator is a linear function and since it is a linear function, we can separate both linear function without restriction as shown;

$\dfrac{1}{(x-1)(x-9)} = \frac{A}{(x-1)} + \frac{B}{(x-9)}$ where A and B are the unknown constant which are numerical values.
