-3 1/3 is -10/3. B is the same as 1b so you can change it to 3/3b. -10/3+3/3b is -7/3b

Find the value of x to the nearest tenth.
nlexa [21]

Answer:

x = 14.7

Step-by-step explanation:

Using the sine rule

\frac{a}{sin(A)}  = \frac{b}{sin(B)}  = \frac{c}{sin(C)}

Substitute the given values.

\frac{7}{sin(20)}  = \frac{x}{sin(46)}

Rearrange the equation to get x on it's own.

\frac{7sin(46)}{sin(20)}  = x

x = 14.72246211

x = 14.7 (1dp)

The distribution of individual incomes in the United States is strongly skewed to the right. In 2013, the mean and median income
vesna_86 [32]

Answer:

The mean would be $322,343 and the median would be $196,723.

Step-by-step explanation:

Since the distribution of individual incomes is skewed to the right, it means that the distribution has a long right tail.

Drawing a distribution with this characteristic, we can see how the majority of the data falls into the left side of the graphic, meaning that a lot of people receive less income. Following this reasoning, the mean which is the amount of the data (in this case individual income) divided by the amount of people, would be the higher number, meaning that the few people who earn more money would influence in making this number higher.

Following this reasoning, the median (which is not influenced by this difference) would be the less high number.

Use the formula A = P(1 + r)" to solve.
Llana [10]

Answer:

Rate = 0.45 or 45%.

Step-by-step explanation:

20184 = 9600(1 + r)^2

(1 + r)^2 = 20184/9600 = 2.1025

Taking square roots of both sides:

1 + r = 1.45

r = 1.45 - 1 = 0.45.
