Convert the radian measure to degrees. (Round to the nearest hundredth when necessary): −5π8

xxMikexx [17]

Answer:

$\frac{-5}{8}\pi =-112.5$

Step-by-step explanation:

We know that 1π rad=180°

Hence we can use a proper relation

$\pi = 180\\-5\frac{\pi }{8}=x$

Solving for x results

$x=\frac{-5}{8}*180=\frac{-5}{2}*45=\frac{-225}{2}=112,5$

Clarissa's income puts her in the bottom tax bracket (10%) last year. During the same year, she earned $250 in dividends and $75

Art [367]

Answer:

75 in coupons.

250 in dividends.

profit of 600 - 425 = 175 from her stock investment.

her total income is 250 + 75 + 175 = 500.

if all of this is taxed at 10%, then her tax will be 500 * .1 = 50.

A study was conducted to determine the percent of children that want to grow up work in the same career as a parent. In a sample

Irina-Kira [14]

Answer:

Step-by-step explanation:

From the information given,

Number of sample, n = 200

Probability of success, p = 43/100 = 0.43

q = 1 - p = 1 - 0.43

q = 0.57

For a confidence level of 95%, the corresponding z value is 1.96.

The formula for determining the error bound for the proportion is

z × √pq/n

= 1.96 ×√(0.43 × 0.57)/200

= 1.96 × 0.035 = 0.0686

The upper boundary of the population proportion is

0.43 + 0.0686 = 0.5

The lower boundary of the population proportion is

0.43 - 0.0686 = 0.4

The error in the solution is

phat = 0.43/200 = 0.00215

Also,

[-0.0043, 0.0086] is wrong

Using approximations to 1 significant figure,

malfutka [58]

Answer:

200

Step-by-step explanation:

Given:

0.482 x 61.2^2 ÷ √98.01

61.2^2 = 3745.44

√98.01 = 9.9

So,

0.482 × 3745.44 ÷ 9.9

= 1,805.30208 ÷ 9.9

= 182.35374545454

To one significant figure

= 200

One significant figure means only 1 non zero value and others are zero
