What’s the mean median mode range q1 q3 iqr mad of 250 250 500 640 640 640 720 720

Mean: 545

Median: 640

Mode: 640

Range: 470

Step-by-step explanation:

Mean: 250+250+500+640+640+640+720+720= 4360, there are 8 numbers,

4360÷8= 545

Mode: The most common number

Range: You take the largest (720) and subtract it from the smallest (250). 720+250= 470

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

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°
