Margaret drives 188 miles<br> with 8 gallons of gas. Find the unit rate
8090 [49]

The unit rate will be "23.5 miles/gallon". In the below segment, a further solution to the given question is provided.

Given values in the question are:

Total distance,

= 188 miles

Total gas used,

= 8

Now,

⇒ The rate of gas consumption will be:

= \frac{Total \ distance}{Total \ gas \ used}

By putting the given values in the above formula, we get

= \frac{188}{8}

= 23.5 \ miles/gallon

Thus the above is the appropriate solution.

An average light bulb manufactured by the Acme Corporation lasts 300 days with a standard deviation of 50 days. Assuming that bu
notsponge [240]

Answer:

1. 90% 2. 10% 3. 50%

Step-by-step explanation:

Standard Deviation (σ) = 50 days

Average/Mean (μ) = 300days

Probability that it would last more than 300 days = P(Bulb>300 days)

We will assume there are 365 days in a year.

P(Bulb>300 days)  implies that the bulb would

Using the normal equation;

z = standard/normal score = (x-μ)/σ where x is the value to be standardized

P(Bulb>300 days) implies x = 365 days

Therefore z = (365-300)/50 = 1.3

Using the normal graph for z=1.3, probability = 90%

2. P(Bulb<300 days) = 1 - P(Bulb>300 days)\

P(Bulb<300 days) = 1 - 0.9

P(Bulb<300 days)  = 10%

3. P(Bulb=300 days) implies z=0 since x=300

Using the normal graph for z=0, probability =50%

What is 33.61111111 in fraction form
madreJ [45]

The correct answer is:   " \frac{33,611}{1,000} " .

____________________

<u>Step-by-step explanation</u>:

Based on the assumption that the "1" repeats infinitely; in the given value:

  " 33.61111111 ...." ;

_______

Note that the "611" ; after the decimal point;  this goes to the "thousandths";  

place (is "3 (three) digits long.").

_______

As such; we rewrite the number as:

_______

" \frac{33.611}{1} " ;  

and we multiply BOTH the "numerator" And the "denominator" by: "1000" :

_______

  →  " \frac{(33.611)*(1000)}{(1)*(1000)} " ;

to get:

  →  " \frac{33611}{1000} " ;  →  which cannot be reduced any further.

_______

The correct answer is: " \frac{33,611}{1,000} " .

_______

Hope this is helpful to you!

 Wishing you the best!

What is the correct simplified version of the expression 32x + 8 - 34x?
MakcuM [25]

Answer:

  -2x +8

Step-by-step explanation:

The terms involving x are "like" terms, so their coefficients are added when the terms are combined.

  = 32x -34x +8

  = (32 -34)x +8 . . . . . x is factored out according to the distributive property

  = -2x +8
