Find the distance between the points (-16,10) and (2,-14)
Andrei [34K]

Answer:  The distance is 30

Step-by-step explanation:

To find the distance between the two points,find the difference between the x and y values, square them and add them to find their square root.

10 - (-14) = 24

-16 - 2=   -18

24^2 + 18^2 = d^2  where d is the distance

576 + 324 = d^2  

900 =d^2

d = \sqrt{900}

d= 30

OPTIONS OVER HERE AND FOR A BETTER VIEW OF THE QUESTION LOOK AT THE PICTURE THANK YOU AND PLEASE HELP!!!
AlladinOne [14]

Answer:

a = 15

b = 7

c = 4

Step-by-step explanation:

Given in the question an expression \sqrt[4]{15}^{7}

This expression can be written as 15^{\frac{7}{4} }

As we know that roots are most often written using a radical sign, like this, \sqrt[n]{x} But there is another way to represent the taking of a root.

You can use rational exponents instead of a radical. A rational exponent is an exponent that is a fraction. For example, \sqrt[n]{x} can be written as x^{\frac{1}{n} }

Secondly two powers having same base can be multiply

x^{n}(^{m})=x^{nm}

g Recall the method used to obtain a confidence interval for the difference between two population means for matched samples. (a
Dovator [93]

Answer:

Step-by-step explanation:

Population 1: 11, 7, 9, 12, 13, 15, 15

Population 2: 6, 6, 4, 5, 8, 13, 12

Mean = sum of terms/number of terms

For population 1,

number of terms = 7

Mean = (11 + 7 + 9 + 12 + 13 + 15 + 15)/7 = 82/7 = 11.7

For population 2,

Number of terms = 7

Mean = (6 + 6 + 4 + 5 + 8 + 13 + 12)/7 = 7.71

The difference value for each element is

(11 + 7 + 9 + 12 + 13 + 15 + 15) - (6 + 6 + 4 + 5 + 8 + 13 + 12) = (5, 1, 5, 7, 5, 2, 3)

The difference between the two means is

Mean of population 1 - mean of population 2

Difference = 11.7 - 7.71 = 3.99
