What's the first and third quartile of -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 7, 7, 7

There are 14 total numbers.

Make a list of the 7 lowest numbers:

-5, -4, -3, -2, -1, 0 , 1

The first quartile is the middle value of the lower half of numbers

Since there are 7 numbers ( odd number), the middle value is the middle number, which is -2

Now make a list of the 7 highest numbers:

2, 3 , 4, 5 , 7, 7, 7

The 3rd quartile is the middle value of the higher half of numbers.

Again because there are 7 numbers ( odd number), the middle value is the middle number, which would be 5.

First quartile = -2

Third quartile = 5

i dont know it

step-by-step explanation:

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
