Answer:

more classmates like hip-hop

step-by-step explanation:

percentages (%) are out of 100

classmates: 62% of 80 is the same thing as

\frac{62}{100}  \times 80 = 50 \: rounded \: up

relatives: 70% of 60 is the same thing as

\frac{70}{100}  \times 60 = 42

we can clearly see that more classmates like hip-hop

Solve for x: 2 over 5 plus 3 over 5 x equals quantity x plus 5 over 10
krok68 [10]
(2/5)+(3/(5x))=(x+5)/10
nasty fractions, we hates it forever

so

get rid of all those nasty fractions
multiply both sides by 10x
4x+6=x(x+5)
distribute
4x+6=x^2+5x
minus (4x+6) from both sides
0=x^2+x-6
factor
0=(x-2)(x+3)
set each to zero
0=x-2
2=x

0=x+3
-3=x

x=-3 and 2

Write the equation of the line that satisfies the given conditions. Express the final equation in standard form.
Anton [14]

Answer:

The equation of line with given points and perpendicular to y-axis is

y = - 7  

Step-by-step explanation:

Given as :

The given points as ( - 10 , - 7)

The equation of line is Y = mX + c

So The line will satisfy given points

Or,  - 7 = m ( -10 ) + c

Now This line is perpendicular to y- axis

∴ The slop of line perpendicular to  y axis is 0

So, - 7= 0 + c

or, c = - 7

∴ Equation of line is y = 0 + c

Or,        y = - 7

Hence The equation of line with given points and perpendicular to y-axis is y = - 7      Answer

In a large data set the 40th percentile is 125 and the 82nd percentile is 158. Approximately what percentage of observations lie
liq [111]

Answer:

42% of observations lie between 125 and 158.

Step-by-step explanation:

Interpretation of a percentile

When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.

Two values have a percentile, how many are between then?

In this example, y is larger than x.

When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.

When a value Z is said to be in the yth percentile of a set, y% of the values in the set are lower than V and (100-y)% of the values in the set are higher than V.

Also, (y-x)% of the values are between V and Z.

In this problem, we have that:

125 is the 40th percentile

158 is the 82nd percentile

Approximately what percentage of observations lie between 125 and 158

82 - 40 = 42% of observations lie between 125 and 158.
