Hello!

✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧

❖ Mai has $4.90 left.

Add $4.35 and $5.25 to get the total amount that she spent:

$4.35 + $5.25 = $9.60

Then subtract to get the amount of money left:

$14.50 - $9.60 = $4.90

Samples of rejuvenated mitochondria are mutated (defective) in 3% of cases. Suppose 15 samples are studied, and they can be cons

stiks02 [169]

Answer:

C) At most one sample is mutated

Step-by-step explanation:

If there are 15 samples, it means that 15 is the total (100%) of samples. Then, if we know that there is a chance that 3% are mutated, then we calculate the 3% of 15:

$Mutated= \frac{3. 15}{100} = 0.45$

This means that at most one sample is mutated, as this result is not zero (we discard answer A), and 0.45 is not more than half of the samples.

Jerry has a part-time job at a supermarket. The ordered pairs show the number of hours he worked for (input values) and the numb

Karo-lina-s [1.5K]

Answer:

Yes

Step-by-step explanation:

The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).

The number of hours worked is $x$ and the money earned is $y$ .

Let us divide the values of $y$ by $x$

$\dfrac{72}{6}=12$

$\dfrac{96}{8}=12$

$\dfrac{66}{5.5}=12$

$\dfrac{108}{9}=12$

$\dfrac{84}{7}=12$

The fuction which defines the above ordered pairs is $y=12x$

It can be seen that the amount of money earned is 12 times the number of hours worked.

So, per hour Jerry earns 12 dollars.

Hence, the ordered pairs are relation.
