Answer:

<em>Each axis has a label. The axis label shows the name of the variable and its unit. The data points are the values plotted on the graph. Each point is plotted using a pair of values for the variables (the x-coordinate and the y-coordinate).</em>

What is the probability that a stamp chosen at random is a commemorative or a special delivery stamp?

Ksivusya [100]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

$P(\text{ getting a commemorative stamp})=0.16$

and

$P(\text{getting a special delivery stamp})=0.18$

So, we need to find,

$P(\text{getting either a commemorative or a special delivery stamp})\\=P(\text{getting a commemorative stamp})+P({\text{ getting a special delivery stamp})$

(∵they are independent events .)

$P(\text{getting either a commemorative or a special delivery stamp})\\=0.16+0.18\\=0.34$

So, option 'D' is correct.

Patty has 44 coins, all nickels, dimes and quarters, worth a total of $6.45. She has 3 times as many dimes as nickels. Set up an

kherson [118]

Answer: There are 7 nickles, 21 dimes and 16 quarters.

Step-by-step explanation:

Since we have given that

Number of coins = 44

Let the number of nickels be 'x'.

Let the number of dimes be '3x'.

Let the number of quarters be

$44-(x+3x)\\\\=44-4x$

According to question, we get

$0.05x+0.10(3x)+0.25(44-4x)=6.45\\\\0.05x+0.3x+11-x=6.45\\\\-0.65x=6.45-11\\\\-0.65x=-4.55\\\\x=\dfrac{4.55}{0.65}\\\\x=7$

So, there are 7 nickles,

3x = $3\times 7=21$

$44-4x=44-4\times 7=44-28=16$

Hence, there are 7 nickles, 21 dimes and 16 quarters.

If f(3)=2x^3 -2 , what is the value of f(2)

iris [78.8K]

I'm not sure about this but will give it a try:

Let f(n) = 2xⁿ - 2

Then f(3) = 2x³ - 2

So, f(2) = 2x² - 2
