Answer:

10

Step-by-step explanation:

( - 1, - 2 )

Let,

x1 = - 1

y1 = - 2

( - 9, 4 )

Let,

x2 = - 9

y2 = 4

Formula : -

Distance = √ [ ( x1 - x2 )² + ( y1 - y2 )² ]

Distance = √ [ ( - 1 - ( - 9 ) )² + ( - 2 - 4 )² ]

               = √ [ ( - 1 + 9 )² + ( - 6 )² ]

               = √ [ 8² + ( - 6 )² ]

               = √ [ 64 + 36 ]

               = √100

Distance = 10

The histogram shows the prices for six-packs of adult socks and six-packs of kid socks at a store. What is true about the variab
Agata [3.3K]

Answer:

a. There is more variability in the prices of kid socks because they have a greater range.

Step-by-step explanation:

A measure of variability is a summary statistic that represents the amount of dispersion in a dataset. Common examples are range, interquartile range (IQR), variance, and standard deviation.

From the histogram

Highest Number of Packs of Adult Socks = 7

Lowest Number of Packs of Adult Socks = 5

Range = 7 - 5 =2

Highest Number of Packs of Kid Socks = 7

Lowest Number of Packs of Kid Socks = 4

Range = 7-4 = 3

We conclude that there is more variability in the prices of kid socks because they have a greater range.

The correct option is A.

Determine if the rates are equivalent. Explain your reasoning.5 cans of soup for $3.75; 8 cans of soup for $6.00
Liula [17]

Answer:

They are equivalent

Step-by-step explanation:

Since 3.75 divided by 5 is .75 that means that 6 divided by 8 would have to also be .75 which, if you divide it, it is.

Given loga (m) = 10 and loga (n) = 25 , find loga (m * n ^ 2)
mina [271]

The result of the log function log_a (m * n ^ 2)  is 60

According to the law of logarithm if log_ab=y then b=a^y

Given the following expressions

log_am=10\\log_an=25

This can be expressed as

m =a^{10} \ and \ n = a^{25}

Substitute the value of m and n into the expression log_a (m * n ^ 2) to have:

log_a (m * n ^ 2) = log_a(a^{10}\times a^{50})\\=log_aa^{60}\\=60log_aa\\=60(1) \\= 60

This shows that the result of the log function log_a (m * n ^ 2)  is 60
