Answer:

angle E, the measure is 135

angle J, the measure is 105

Step-by-step explanation:

Supplementary angles add up to 180 degrees.

We are to identify an angle that is supplementary to angle M form the given parallel line.

From the fist diagram, angle E and angle F are supplementary to angle M because they form adjacent angles on a straight line with angle M.

If angle m is 45 degrees, then the value of its supplement is 180-45=135

From the second diagram, angle H,angle J and angle P are supplementary to angle M.

If angle M is 75 degrees, the its supplement is 180-75=105

F(x) = -3x-3 g(x) =2x^3+2<br> Find f(6) and g(-3)

wlad13 [49]

Answer:

$f(6)=-21\\\\g(-3)=-52$

Step-by-step explanation:

When given the following two functions,

$f(x) =-3x-3\\g(x)=2x^3+2$

One is asked to evaluate the functions for, (f(6)) and (g(-3)). One can do this by substituting the values (6) into the function (f) and (-3) into the function (g). These values will replace the parameter (x).

$f(6)=-3(6)-3\\$

Simplify,

$f(6)=-18-3\\f(6)=-21$

Now repeat this process for the guncion (g(x)) to evaluate for (g(-3))

$g(-3)=2(-3)^3+2$

Simplify,

$g(-3)=2(-27)+2\\g(-3)=-54+2\\g(-3)=-52$

A shipment of beach balls with a mean diameter of 28 cm and a standard deviation of 1.3 cm is normally distributed. By how many

dlinn [17]

Answer: D.) 3

Step-by-step explanation:

Given: Mean diameter: $\mu=28\ cm$

Standard deviation: $\sigma=1.3\ cm$

The required number of standard deviations is given by :-

$z=\frac{X-\mu}{\sigma}\\\\\Rightarrow\ z=\frac{31.9-28}{1.3}\\\\\Rightarrow\ z==3$

Hence, a beach ball with a diameter of 31.9 cm is 3 standard deviations differ from the mean.

Answer:

$y=\frac{306}{7}$ is the answer.

In decimal y = 43.71

Step-by-step explanation:

Given:

y varies directly with x .

Also x = 7 when y = 18

To Find:

y = ? when x = 17

Solution:

y varies directly with x .

i.e. y is directly proportional to x

∴ $y = k\times x$

Where

k = constant of proportionality {Remain Same}

First we will find constant of proportionality k,

∴ When x = 7 and y = 18 we have

∴ $18 = k\times 7\\\\k=\frac{18}{7}$

Now when x= 17 and $k=\frac{18}{7}$ we have

∴ $y = k\times x$

∴ $y=\frac{18}{7}\times 17\\\\y=\frac{306}{7}\\\\ y=43.71$
