a jar contains 30 red, 40 blue, and 50 white buttons. you pick one button at random, find the probability that is not white
Jet001 [13]

Answer:

<em>The probability that the button is not white is </em><em>0.583</em>

Step-by-step explanation:

The jar contains 30 red, 40 blue, and 50 white buttons.

In total there are 120 buttons in the jar. So,

|\ S\ |=120

Let us assume that, A be the event of picking white buttons, so

|\ A\ |=50

So the probability of picking white button is,

P(A)=\dfrac{|\ A\ |}{|\ S\ |}=\dfrac{50}{120}

Then the event A^c will be not picking up white buttons, so the probability of not picking up white buttons is,

P(A^c)=1-P(A)=1-\dfrac{50}{120}=\dfrac{70}{120}=\dfrac{7}{12}=0.583

If f(x)=3x-1 and g(x)=x+2,find (f+g)(x)
KiRa [710]

Answer:

(f + g)(x) = 4x + 1

Step-by-step explanation:

Given f(x) = 3x - 1 and g(x) = x + 2, find (f + g)(x):

We can rewrite (f + g)(x) as f(x) + g(x), and solve the composite functions through addition:

f(x) + g(x) = (3x - 1) + (x + 2)

Combine like terms:

f(x) + g(x) = 3x + x + 2 - 1 = 4x + 1

Therefore, (f + g)(x) = 4x + 1.

Answer:

  3.  m∠A < 80°

Step-by-step explanation:

The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.

If we assume that angle measures cannot be zero, then we must have ...

  m∠A +m∠N = 80°

  m∠A = 80° -m∠N

Since m∠N > 0, the measure of angle A must be less than 80°.

This conclusion matches choice 3.

Flip a coin 10 times and record the observed number of heads and tails. For example, with 10 flips one might get 6 heads and 4 t
zepelin [54]

Answer:

The greater the sample size the better is the estimation. A large sample leads to a more accurate result.

Step-by-step explanation:

Consider the table representing the number of heads and tails for all the number of tosses:

Number of tosses    n (HEADS)        n (TAILS)            Ratio

            10                         3                      7                    3 : 7

           30                         14                    16                   7 : 8

          100                        60                   40                  3 : 2

Compute probability of heads for the tosses as follows:

  • n = 10 tosses

        P(\text{HEADS})=\frac{3}{10}=0.30

The probability of heads in case of 10 tosses of a coin is -0.20 away from 50/50.

  • n = 30 tosses

        P(\text{HEADS})=\frac{14}{30}=0.467

The probability of heads in case of 30 tosses of a coin is -0.033 away from 50/50.

  • n = 100 tosses

        P(\text{HEADS})=\frac{60}{100}=0.60

The probability of heads in case of 100 tosses of a coin is 0.10 away from 50/50.

As it can be seen from the above explanation, that as the sample size is increasing the distance between the expected and observed proportion is decreasing.

This happens because, the greater the sample size the better is the estimation. A large sample leads to a more accurate result.
