Answer: $x=7$

Step-by-step explanation:

By the Intersecting Secants Theorem, we know that:

$(5)(x+5)=(6)(6+4)$

Having this, we can find the value of "x" by solving for "x":

Applying Distributive property:

$(5)(x+5)=(6)(24)\\5x+25=60$

Subtract 25 from both sides of the equation:

$5x+25-25=60-25\\5x=35$

And finally dviding both sides of the equation by 5, we get:

$\frac{5x}{5}=\frac{35}{5}\\x=7$

The distribution of the number of hours people spend at work per day is unimodal and symmetric with a mean of 8 hours and a stan

Wewaii [24]

Answer: 95% of all people work between 7 hours and 9 hours per day and It is true.

Step-by-step explanation:

Since we have given that

Mean = 8 hours

Standard deviation = 0.5 hours

According to Empirical Rule,

at 95% confidence, it lies within 2 standard deviations from the mean

so, lower value is given by

$mean-2\times sd\\\\=8-2\times 0.5\\\\\=8-1\\\\=7\ hours$

upper value is given by

$mean+2\times s.d\\\\=8+2\times 0.5\\\\=8+1\\\\=9\ hours$

Hence, 95% of all people work between 7 hours and 9 hours per day.

Therefore , it is true.

Which of these is a unit of density?

Naddika [18.5K]

<h3><u>Answer:- </u></h3>

$\longrightarrow \textsf{The unit of density is\;}$ $\sf kg/m^3$

<h3><u>Solution</u> :-</h3>

$\green{ \underline { \boxed{ \sf{Density = \frac{Mass}{Volume}}}}}$

$\longrightarrow$ The unit of mass is kg and unit of Volume is m³ . Since density is division of mass by volume , the corresponding units will also get divided and unit of density would come out to be kg/m³

<u>Some basic </u><u>derived </u><u>Units :- </u>

area => m²
volume cubic meter => m3
speed meter per second => m/s
acceleration => m/s²
mass density meter => kg/m3
specific volume cubic meter per kilogram m³/kg
