The question in English
<span>Each of the 25 students in the class has  made a journal on Monday. Knowing that every day a page was used and that the month is 31 days, find out how many pages the logs of all students.

</span>Let
x--------------> total students
y--------------> total days in a month
z--------------> total page used per one student in 1 day
T--------------> total page used per total students in 1 month

we know that
x=25 students
y=31 pages
z=1 page

T=[x]*[y]*[z]------------> T=[25]*[31]*[1]------------> T=775 pages

the answer is 775 pages

Find the probability that a Type A bulb lasts at least 300 hours and a Type B bulb lasts at least 400 hours.
barxatty [35]

Answer:

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

Step-by-step explanation:

We require more information by I will explain in principle:

If Type A has at least 300 hours and Type B at least 400 hours.

(X>3)(Y>4)=P(X>3)P(X>4)

You need to determine the Probability density function of X and Y and then subtract 1 from both

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

This will give you the probability of the expression.

Tell whether the exact answer is reasonable 2.411. Mr. Jones sells gaones sells gardening supplies. A shovel sells for $19.He sa
dezoksy [38]
If he is selling shovels at $19 each, the answer of $153 would be incorrect. If you take $153 and divide that by 8 (shovels) you will get each shovel being a price of $19.125 each. 
The overall answer of $153 could be reasonable but the overall price from selling 8 shovels will actually be $154 not $153.

Which expression is equivalent to...? Assume... screenshots attached, please help!
larisa [96]

Answer:

\frac{\sqrt[3]{5} }{3x}

Step-by-step explanation:

Ok, let's do this step by step....

\sqrt[3]{\frac{10x^{5} }{54x^{8} } }

Let's first simplify the x's:

\sqrt[3]{\frac{10}{54x^{3} } }

Then we breakdown the 54 as 2 * 27 then simplify with the 10 above.

\sqrt[3]{\frac{10}{2 * 27x^{3} } } = \sqrt[3]{\frac{5}{27x^{3} } }

Now, we can rewrite this as the following and solve the bottom part:

\frac{\sqrt[3]{5} }{\sqrt[3]{27x^{3} } } = \frac{\sqrt[3]{5} }{3 \sqrt[3]{x^{3} } } = \frac{\sqrt[3]{5} }{3x}

The solution is

\frac{\sqrt[3]{5} }{3x}
