Rewrite the expression 225 divided by 5/8 as 225 x 8/5. So, the quotient says a sloth may move 360 feet in 1 hour. Rewrite 90 mi

nutes as 1 1/2 hour. Multiply by 1 1/2 to get feet in 90 minutes.

27. In constructing a confidence interval estimate of the population mean you decide to select 49 random observations to get you
Alika [10]

Answer:

1) a.) Your confidence interval estimate is narrower

2) c.) The width of a confidence interval estimate for a proportion will be narrower for 90% confidence level than for a 95% confidence level

Step-by-step explanation:

Confidence Interval can be stated as  M±ME where

  • M is the sample mean
  • ME is the margin of error

Margin of Error determines the range of the confidence interval around the mean.

Margin of error (ME) of the mean can be calculated using the formula

ME=\frac{z*s}{\sqrt{N} } where

  • z is the corresponding statistic in the given confidence level
  • s is the standard deviation of the sample(or the population if it is known)
  • N is the sample size

From the formula we can reach the following conclusions:

  • As N increases, ME decreases.
  • as confidence level increases, corresponding statistic increases, and thus margin of error increases.

Since your sample size (49) is bigger than your friend's (36), your confidence interval is narrower, because margin of error is narrower.

Since the confidence level 90% has smaller statistic than the confidence level 95%, its confidence interval is narrower.

That is, we can estimate <em>narrower</em> confidence intervals with less confidence.

The exterior angles of a triangle are (2x+10), (3x+5), and (2x+40) 0.
Roman55 [17]

Step-by-step explanation:

i. (2x+10)+(3x+5)+(2x+40) = 360

2x+3x+2x+10+5+40= 360

7x+55 =360

7x=360-55

<u>7x</u>= <u>3</u><u>05</u>

7. 7

x= 43.57=43.6

ii. 2x+10= 180

2x=180-10

<u>2</u><u>x</u>= <u>1</u><u>7</u><u>0</u>

2. 2

x=85

3x+5 =180

3x=180-5

<u>3</u><u>x</u>=<u>1</u><u>7</u><u>5</u>

3. 3

x= 57.5

2x+40=180

2x=180-40

<u>2x</u>=<u>140</u>

2. 2

x= 70

From the above 3x+5 which is 57.5 is the smallest interior angle of the triangle

iii. The largest interior angle of the triangle is 2x+10 which is 85
