Question:

A fair die is tossed.

Find the probability of obtaining an even number

Answer:

sample space=(1,2,3,4,5,6)

number of favourable outcomes=3

Event A= (outcome is even)

= (2,4,6)

Total number of outcomes=6

Thus, P(even number)=3/6

=1/2

Question 2:

A drawer contains 10 identical handkerchiefs of which 2 are white, 5 are blue, and 3 are pink. A handkerchief is drawn at random. what is the probability that it is white or pink?

Answer:

total number of outcomes=10

P(the handkerchief is white or pink)=2+3/10

=5/10

=1/2

Suppose we want to test the claim that the majority of adults are in favor of raising the vote age to 21. Is the hypothesis test

Fofino [41]

Answer:

The hypothesis test is right-tailed.

Step-by-step explanation:

We are given that we want to test the claim that the majority of adults are in favor of raising the voting age to 21.

Let p = <u><em>proportion of adults who are in favor of raising the voting age to 21</em></u>

So, Null Hypothesis, $H_0$ : p $\leq$ 50%

Alternate Hypothesis, $H_A$ : p > 50%

As we know that the majority is there when we have more 50% chance of happening of that event.

Here, the null hypothesis states that the proportion of adults who are in favor of raising the voting age to 21 is less or equal to 50%.

On the other hand, the alternate hypothesis states that the proportion of adults who are in favor of raising the voting age to 21 is more than 50%.

This shows that our hypothesis test is right-tailed because in the alternate hypothesis, the greater than sign is included.

1/2 +3/4 simplest form ??

Feliz [49]

1/2 + 3/4

1/2 = 2/4 therefore

2/4 + 3/4 = 5/4

5/4 (improper fraction) = 1 1/4 (mixed fraction)

Suppose there are two circles where the radius of one circle is twice the radius of the other circle. Each circle has an arc whe

Artemon [7]

Answer:

$L=2l$ where $l,L$ denote arc lengths of two circles

Step-by-step explanation:

Let $l,L$ denote arc lengths of two circles, $r,R$ denote corresponding radii and

$\alpha _1\,,\alpha _2$ denote the corresponding central angles.

So,

$l=r\alpha _1$ and $L=R\alpha _2$

This implies $\alpha _1=\frac{l}{r}$ and $\alpha _2=\frac{L}{R}$

As each circle has an arc where the measures of the corresponding central angles are the same, $\alpha _1=\alpha _2$

$\frac{l}{r}=\frac{L}{R}$

As radius of one circle is twice the radius of the other circle,

$R=2r$

$\frac{l}{r}=\frac{L}{2r}\\\frac{l}{1} =\frac{L}{2}\\L=2l$
