K/5+14=13 what is the answer and how you got the answer.

abruzzese [7]

Answer:

$\frac{k}{5+14} = 13 : k = 247\\$

Step-by-step explanation:

$\frac{k}{5+14} = 13$

Multiply both sides by 19:

$\frac{19k}{5+14} = 13 * 19$

Simplify:

$k = 247$

Hope I helped, if so may I get brainliest and a thanks?

Thank you, have a good day! =)

According to the US Census, the percent of residents aged 65 or older in the 50 states and District of Columbia has mean 13.26%

Over [174]

Answer:

z = -2.13

The standardized score for the state of Colorado is negative and this means the score is smaller than the mean.

Step-by-step explanation:

The above question can be solved using z score.

The formula for z score is given as:

z = (x-μ)/σ,

where

x is the raw score = 9.7%

μ is the population mean = 13.26%

σ is the population standard deviation = 1.67%

z = z score or standardize score

Hence,

z = 9.7 - 13.26/1.67

z = -2.13174

Approximately z = -2.13

Therefore, the standardized z score for the state of Colorado is negative and this indicates that the score is below or smaller than the mean.

Identify the 27th term of an arithmetic sequence where a1 = 38 and a17 = -74. . A. -20.5 . B. -151 . C. -22.75 . D. -144 . .

Dennis_Churaev [7]

In order to solve for a nth term in an arithmetic sequence, we use the formula written as:

an = a1 + (n-1)d

where an is the nth term, a1 is the first value in the sequence, n is the term position and d is the common difference.

First, we need to calculate for d from the given values above.
a1 = 38 and a17 = -74


an = a1 + (n-1)d
-74 = 38 + (17-1)d
d = -7

The 27th term is calculated as follows:

a27 = a1 + (n-1)d
a27= 38 + (27-1)(-7)
a27 = -144 -----------> OPTION D

Write an equation of the line that passes through 7,10 and is perpendicular to the line y=1/2-9

kow [346]

An equation of the line that passes through (7,10) and is perpendicular to the line y=1/2x-9 is $y=-2x+24$

Step-by-step explanation:

We need to write an equation of the line that passes through 7,10 and is perpendicular to the line y=1/2x-9

Note: Considering the line y=1/2x-9

For finding an equation of line we need

Slope (m)
y-intercept (b)

The general equation of slope intercept form used is:

$y=mx+b$

The equation of line given is: y=1/2x-9

The new line is perpendicular to the given line So, the slope of new line would be m = -1/m

So, Slope of given line m = 1/2

Slope of required line = -1/m = -2

So, m= -2

Now, for finding y-intercept (b) we need slope m = -2 and the point given (7,10)

Putting values of m, x=7 and y = 10 in the equation of slope intercept form

$y=mx+b\\10=-2(7)+b\\10=-14+b\\b=10+14\\b=24$

So, Equation of required line having slope m = -2 and y-intercept b = 24

$y=mx+b\\y=-2x+24$

An equation of the line that passes through (7,10) and is perpendicular to the line y=1/2x-9 is $y=-2x+24$
