What is the domain of the function f(x) = 5x+2? XS-6 0 x>6 0x<6 O x>-6

1 answer:

I think your equation is wrong. the domain of f(x)= 5x+2 is ALL REAL NUMBERS. That means it’s negative infinity to positive infinity.

There were 6 purple socks and 4 oraange socks without looking and then another without looking (or replacing the first). What is

shusha [124]

Answer:

The probability that he picked 2 purpled socks is <u>0.33</u>.

Step-by-step explanation:

Given:

Number of purple socks, $n(P) = 6$

Number of orange socks, $n(O) = 4$

Two socks are picked without replacement.

Now, total number of socks, $n(T)=N(P)+n(O)=6+4=10$

Probability of picking the first cap as purple cap is given as:

$P(P1)=\frac{n(P)}{n(T)}\\\\P(P1)=\frac{6}{10}=\frac{3}{5}$

Since there is no replacement, the number of socks decreases by 1. Also, if the first sock picked is purple, then number of purple socks is also decreased by 1.

Therefore, probability of picking the second cap as purple cap is given as:

$P(P2)=\frac{n(P)-1}{n(T)-1}\\\\P(P2)=\frac{5}{9}$

Now, probability that both the picked caps are purple is given by their probability product. This gives,

$P(P1\ and\ P2)=P(P1)\times P(P2)\\\\P(P1\ and\ P2)=\frac{3}{5}\times\frac{5}{9}\\\\P(P1\ and\ P2)=\frac{3}{9}=\frac{1}{3}=0.33$

Therefore, the probability that he picked 2 purpled socks is 0.33

Patrick needs 3 4 cup of orange juice for a punch recipe. He has a measuring cup that is 1 8 cup how can Patrick use the 1 8 cup

ki77a [65]

Answer: To find the number of $\dfrac18$ cups required, we will divide To find the number of $\dfrac18$ cups required, we will divide required quantity by $\dfrac18.$ by $\dfrac18.$

Step-by-step explanation:

Patrick needs $\dfrac34$ cups of orange juice.

Capacity of measuring of cup = $\dfrac18$ cup

To find the number of $\dfrac18$ cups required, we will divide required quantity by $\dfrac18.$

Required number of $\dfrac18$ cups = $\dfrac34\div\dfrac18=\dfrac34\times8=3\times2=6$

Hence, six $\dfrac18$ cups are required for $\dfrac34$ cups of orange juice..
