Determine single-digit values of M for which the products M*5 end in 5. They are M={1,3,5,7, ...}. Note, for example, that 7*M5 ends in 5, the last digit of 385. Even values of M (as in {2,4,6,8,...} do not have products that end in 5, and thus must be eliminated.

Next, note that if N=5, then M*5 becomes 75, and that 75 multiplied by 5 comes out to 385, which is the desired product.

Noting that L times N*5 (that is, L times 55) = 385, L has to be the same as M, and is in fact 7. Then L times N*5 comes out to 385.

In summary: N=5, M=7 and L=7.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A bike rental company charges a fee per hour.

The charge, in dollars, is the same each hour.

The ordered pairs (3, 13.50) and (5, 22.50) represent the corresponding hours, x, and cost, y.

Then the linear equation is given as

$\begin{aligned} \rm y - 22.5 &= \rm \dfrac{22.5 - 13.5}{5 - 3} (x- 5)\\\\\rm y - 22.5 &= \rm 4.5x - 22.5\\\\\rm y &= \rm 4.5x \end$

Then the rate of change of the function expressed as a unit rate will be

$\rm \dfrac{dy}{dx} = \dfrac{d}{dx} (4.5x )\\\\\dfrac{dy}{dx} = 4.5$

Suppose that 10% of the undergraduates at a certain university are foreign students, and that 25% of the graduate students are f

Deffense [45]

Answer:

0.6154 = 61.54% probability that the student is an undergraduate

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Foreign

Event B: Undergraduate.

There are four times as many undergraduates as graduate students

So 4/5 = 80% are undergraduate students and 1/5 = 20% are graduate students.

Probability the student is foreign:

10% of 80%

25% of 20%. So

$P(A) = 0.1*0.8 + 0.25*0.2 = 0.13$

Probability that a student is foreign and undergraduate:

10% of 80%. So

$P(A \cap B) = 0.1*0.8 = 0.08$

What is the probability that the student is an undergraduate?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.08}{0.13} = 0.6154$

0.6154 = 61.54% probability that the student is an undergraduate

Josue's overtime pay is $6 an hour more than his regular pay. He worked 7 hours at his regular wage and 5 hours at his overtime

adell [148]

The answer is: 7x + 5 (x + 6) = 138 7x + 5x + 30 = 138 12x = 138 - 30 12x = 108 x = 9 $ = regular pay and overtime = 9 + 6 = 15 $...

Please help me with question #6!!!

Bumek [7]

Previous balance:

+ $481,47→ 11/30
- $300,00 → 11/02
- $68,99 → 11 / 10
- $45,00 → 11/15
- $72,75 → 11/17
----------------------------
+ $481,47 - $113,26 =
+ $368,21

new balance:

+ $481,47→ 11/30
- $300,00 → 11/02
- $ $\diagup\!\!\!\! 68,\diagup\!\!\!\!99$ → 11 / 10 for -$58,99
- $45,00 → 11/15
- $ $\diagup\!\!\!\! 72,\diagup\!\!\!\!75$ → 11/17 for $ 0
-------------------------------------------------------------------------------------
+ $481,47 - $196,01 =
+$285,46

Answer:
$\boxed{+285,46}$
