Hi plz help . (6 to the power -1 + (3—2) to power -1 whole power -1

Nimfa-mama [501]

$a^{-n} = \frac{1}{a^n}$

$(6^{-1} + (3-2)^{-1})^{-1} = (\frac{1}{6} + \frac{1}{3-2})^{-1} = (\frac{1}{6} + \frac{1}{1})^{-1} = (\frac{7}{6})^{-1} = \frac{6}{7}$

I don’t know how to do this problem and need help getting answer?

3241004551 [841]

Hi!!! So to do this problem, you need to find the mean values for each sample. I will walk you through finding the mean of sample 1: first you want to add all of the values for sample 1, which are 4,5,2,4 and 3. Once you add those values you get 18. Then you must divide that 18 by the number of terms you added. The numbers you added were 4,5,2,4 and 3 like I said earlier which is 5 numbers. You divide 18 by 5 to get your mean, which is 3.6

Answer: (B) Sample 2

sample 1 mean = 3.6

sample 2 mean = 4.2

sample 3 mean = 3.8

sample 4 mean = 4

Answer:

D. 18.68

Step-by-step explanation:

$27\div \frac{5}{3}-6+53\times (\frac{2}{5})^2$

Applying PEMDAS as order of operations.

Solving the exponents first $[(\frac{2}{5})^2=\frac{4}{25}]$

$=27\div \frac{5}{3}-6+53\times \frac{4}{25}$

Multiplying $[53\times \frac{4}{25}=8.48]$

$=27\div \frac{5}{3}-6+8.48$

Dividing $[27\div \frac{5}{3}=16.2]$

$=16.2-6+8.48$

Adding and subtracting.

$=18.68$

Answer:

"what are angles"

Step-by-step explanation:

En la geometría euclidiana, un ángulo es la figura formada por dos rayos, llamados lados del ángulo, que comparten un punto final común, llamado vértice del ángulo. Los ángulos formados por dos rayos se encuentran en el plano que contiene los rayos. Los ángulos también se forman por la intersección de dos planos. Estos se llaman ángulos diedros
