Divide 15 by 3.79 to get your answer.

\frac{15}{3.79} = 3.9

The answer is 3.9 gallons, or you could round to 4.

Answer:


Step-by-step explanation:

The cooler holds 15 liters of water

Give: 1 gallon ≈ 3.79 liters

15 liters of water has how many gallons?

Cross multiplying gives approximately:

(15 × 1) ÷ 3.79 = 3.957783641 gallons = 4 gallons rounded up to nearest gallon.

The cooler holds about 4 gallons.

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 44 o
Cerrena [4.2K]

Answer:

a) No 95% of values will fall between (24;64); 68,27% will fall between (34;54)

b)71,83 % will fall between 34 and 64 ounces

Step-by-step explanation:

Empirical rule establishes, for a  normal distribution with mean μ and σ as standard deviation:

In interval   μ  ±  σ    or   ( μ  +  σ ;  μ  -  σ) we should find 68.27 % of all values of the population, and by simmetry 68.27/2 = 34,14 % should be over the mean and the other half would  be values below the mean

Therefore in our case

μ  +  σ  =  44 + 10  =  54

And

μ  -  σ  = 44 - 10   = 34

a) Then  68,34 % of values will fall in this interval

We know now that value 34 is 1* σ   below the mean, and is at the limit of 34,14 %

b) μ  +  2*σ  =   44 * 2*10  =  44 + 20  =  64

64 is the upper limit for the interval   μ  +  2*σ  and we know that 95.45 % of all values will fall between (  μ  -  2*σ  ;  μ  +  2*σ ) and by simmetry just one side of this interval (the right side ) will have 95.45/2 = 47;73 %

Then in interval going from ( 34 ; 64 ) we shoud find 47.73 + 34,14

71,83 % of all values will fall between 34 and 64

PLEASE ANSWER ASAP!! e)What is the measure of ∠I? Explain
Zina [86]

Answer:

60^{\circ}

Step-by-step explanation:

From the given figure it is clear that the stop board is a regular hexagon and ∠I is an exterior angle of the regular hexagon.

Exterior angle of a regular polygon with n sides =\dfrac{360^{\circ}}{n}

In a regular hexagon number of sides: n =6

Exterior angle of a regular hexagon =\dfrac{360^{\circ}}{6}=60^{\circ}

Since ∠I is an exterior angle of the regular hexagon, therefore, \angle I=60^{\circ}.
