Since none of the angles equal 90 degrees, it cannot be a right angle.
No two angles are the same measurement, it is not straight.
All three of the angle are not less than 90 degrees it would not be acute.
Since 1 of the angles is over 90 degrees, it would be an OBTUSE angle.

amid [387]

Answer:

The correct conclusion is:

<em>"The doctor can be 95% confident that the mean height of male students at the college is between 63.5 inches and 74.4 inches."</em>

Step-by-step explanation:

A doctor is measuring the average height of male students at a large college.

The doctor measures the heights, in inches, of a sample of 40 male students from the baseball team.

Using this data, the doctor calculates the 95% confidence interval (63.5, 74.4).

The following conclusions is valid:

<em>"The doctor can be 95% confident that the mean height of male students at the college is between 63.5 inches and 74.4 inches."</em>

Since we know that the confidence interval represents an interval that we can guarantee that the target variable will be within this interval for a given confidence level.

For the given case, the confidence level is 95% and the corresponding confidence interval is (63.5, 74.4) which represents the true mean of heights for male students at the college where the doctor measured heights.

Therefore, it is valid to conclude that the doctor is 95% confident that the mean height of male students at the college is within the interval of (63.5, 74.4).

Solve for x in these equations. Verify the solutions.

mojhsa [17]

Answer:

$5(x + 1) + 6(x + 2) = 7(x + 3) \\ 5x + 5 + 6x + 12 = 7x + 21 \\ 11x - 7x = 21 - 17 \\ 4x = 4 \\ x = \frac{4}{4} \\ x = 1$

What is the common difference of the sequence 7, 13, 19, 25....

stellarik [79]

The common difference is 6

Step-by-step explanation:

Given sequence is:

7, 13, 19, 25....

The common difference is the difference between consecutive terms of an arithmetic sequence.

Here,

$a_1 = 7\\a_2 = 13\\a_3 = 19\\a_4 = 25\\d = a_2-a_1 = 13-7 = 6\\d = a_3 - a_2 = 19-13 = 6\\d = a_4-a_3 = 25-19 = 6$

Hence,

The common difference is 6

A map has a scale of 1 cm to 14 km.

Alenkinab [10]

Answer:

Real distance between Manchester and London = 263.2 km

Step-by-step explanation:

Given that:

A map has a scale of 1 cm = 14 km

Ratio = 1 : 14

Distance from Manchester to London = 18.8 cm

Let,

x be the real distance between Manchester and London.

Ratio = 18.8 : x

As the relationship is proportional,

1 : 14 :: 18.8 : x

Product of mean = Product of extreme

14*18.8 = x

x = 263.2 kilometers

Hence,

Real distance between Manchester and London = 263.2 km
