Vinil7 [7]3 years ago
5 0

Answer:

3m = -3

Step-by-step explanation:

You are given

2m - 6 = 8m,

hence,

2m - 8m = 6,

-6m = 6,

m = 6%2F%28-6%29,

m = -1.

Therefore, 3m = -3.

The weight distribution of parcels sent in a certain manner is normal with meanvalue 12 pounds and standard deviation 3.5 pounds
tino4ka555 [31]

Answer:

The parcel with weight less than 20.14 pounds are 99% of all parcels under the surcharge weight.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 12 pounds

Standard Deviation, σ = 3.5 pounds

We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.99

P( X < x) = P( z < \displaystyle\frac{x - 12}{3.5})=0.99  

Calculation the value from standard normal z table, we have,  

\displaystyle\frac{x - 12}{3.5} = 2.326\\\\x = 20.141\approx 20.14  

Thus, parcel with weight less than 20.14 pounds are 99% of all parcels under the surcharge weight.

A car drives 40 miles on local roads at 20 mph, and 180 miles on the highway at 60 mph, w Your dinner bill is $25 before tax. Th
Anastasy [175]

Answer and Step-by-step explanation:

Let's~solve~your~problem!

<em><u>Formula : </u></em>

<u></u>speed=\frac{distance}{time}

<em><u>Solving for time:</u></em>

Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20}  = 2~hours

Time~taken~to~cover~180~miles~on~the~highway~= \frac{180}{60}=3~hours

Total~Time~=~5~hours

<em><u>Solving for distance:</u></em>

<em><u /></em>Total~Distance=40 + 180 = 220<em><u /></em>

<em><u /></em>

<em><u>Average speed:</u></em>

<em><u /></em>\frac{Total~distance}{Total~time}  = \frac{225}{5}  = 44~miles~per~hour<em><u /></em>

PLEASE HELP
Marat540 [252]

Answer:

Triangle DEF is a right, scalene triangle. It is not isosceles, obtuse, acute, or equilateral

Step-by-step explanation:

All we know about m and n are that they are not equal to each other and they are positive. This was given in the problem. See image. Once it is graphed you can see on the graph the lengths of DE and EF. Use Pythagorean theorem to calculate DF. see image.

DE is horizontal and EF is vertical, so you can see their slopes or calculate using a formula. Calculate the slope of DF. Slope is y-y on top of a fraction and x-x on the bottom of the fraction.

Lastly, use midpoint formula to find the midpoints. Average the x's and average the y's to find the x- and y-coordinates of the midpoints. See image.

Finally, DEF is a right triangle. The graph as well as the slopes show us that DE and EF form a right angle. So DEF must be a right triangle (and not obtuse nor acute) We were told that m doesNOT equal n, so the triangle cannot have two equal sides, so it cannot be isosceles (2 equal sides) nor equilateral (3 equal sides) It has 3 different lengths of sides; that is called scalene.
