Answer:

Right angled and a scalene triangle

step-by-step explanation:

A right angled triangle is a triangle that has one of its angles to be 90°.

A scalene triangle is a triangle that has all his angles and sides to be different.

Based on the angles of the triangle given i.e 21°, 69° and 90°, the triangle can be classified as a RIGHT ANGLED TRIANGLE because it contains 90° as one of its angles.

The triangle is also classified as a SCALENE triangle because all the angles of the triangle are different i.e no two or three of the angles are the same.

Answer:

(38.1,88.6)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 38.3

Sample size, n = 695

Alpha, α = 0.05

Population standard deviation, σ = 3.6

95% Confidence interval:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

$38.3 \pm 1.96(\frac{3.6}{\sqrt{695}} ) = 38.3 \pm 0.267 = (38.033,38.567) \approx (38.1,88.6)$

What is the median of this set of data: 593, 588, 540, 434, 420, 398, 390, 375

Aleks04 [339]

Answer:

426

Explanation:

To find the median number in a set of data start by reordering the data from least to greatest.

original data set:

593, 588, 540, 434, 420, 398, 390, 375

data set from least to greatest:

375, 390, 398, 420, 434, 540, 588, 593

Next, you would usually just have to find the middle number in the data set and that would be your median. However, this data set has no one number that is directly in the middle. So, we will add both middle numbers together and then divide our answer by two.

375, 390, 398, 420, 434, 540, 588, 593

420 + 434 = 854

854 ÷ 2 = 426

Therefore, the median of the given data set is 426.

Witch equation in point-slope form contains the point (2,3) and has slope 2

jonny [76]

Answer:

y - 3 = 2(x -2)

Step-by-step explanation:

The point slope form is $y-y_1=m(x-x_1)$ .

Substitute m= 2 and the point (2,3) into the equation to find:

y - 3 = 2(x -2)
