Answer:

2/4 or 1/2

Step-by-step explanation:

The solution is, 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

There are four (4) colors to choose from.

The number of sample space is equal to 4.

With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4.

Similarly, the probability of landing on yellow on the second spin is 1/4.

so, we get,

           P = (1/4)(1/4)  

             P = 1/16

Answer: 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin

Answer:

x = 2[tex]\sqrt{5}[/tex]

Step-by-step explanation:

'x' can represent the hypotenuse of a right triangle with a base of 4 (11-7) and a height of 2

use Pythagorean Theorem to find 'x':

2² + 4² = x²

4 + 16 = x²

x² = 20

x = [tex]\sqrt{20}[/tex]

x = [tex]\sqrt{4}[/tex]·[tex]\sqrt{5}[/tex]

x = 2[tex]\sqrt{5}[/tex]

Answer:

a) x = 1500

b) m = 2.5

c) n = 3

d) x = 4

e) x = 2

Step-by-step explanation:

Just remember that whatever you do to one side of the equation, you must do to the opposite side. Your aim is to isolate x.

Answer:

x = 65

Step-by-step explanation:

All angles in the triangle equal 180

Set up your formula as

180 = x+75+40

180-75-40=x

65=x

Answer: 10 degrees

Step-by-step explanation:

Since it is a right triangle the angle is 90 degrees.

So, 90 degrees -50 degrees is equal to 40 degrees.

40 divided by 4 is 10.

So your answer is 10 degrees.

Sin E= 0. 198.

E= 11.42°

Step-by-step explanation:

using Pythagoras theorem.

Hyp²= base² + height ².

101²= 99²+x²

x²= 101²-99²

x²=10201-9801.

x²=400

x=√400

x=20

sin E = opposite

________

adjacent.

sin E= 20

__

101.

sin E=0.198.

E= sin^-1(0.198)

E= 11.42°

The correct range is (80, 112).

The correct option is (D).

Mean is also said to be arithmetic mean. The meaning of mean is to evaluate the average. It is defined as the average of the given numbers.

As per the given data:

We are given the mean of the sample.

The mean of the sample = 96

In each option, a range is given.

We have to find out which is the correct range for the given mean.

For a range (a, b) the mean is given by:

mean = (a + b)/2

By using the above definition and checking all the options:

For (76, 108)

mean = (76 + 108)/2 = 92, Not the correct range

For (82, 114)

mean = (82 + 114)/2 = 98, Not the correct range

For (78, 110)

mean = (78 + 110)/2 = 94, Not the correct range

For (80, 112)

mean = (80 + 112)/2 = 96, The correct range

The correct range is (80, 112).

Hence, the correct range is (80, 112).

Answer: The answer is B.

Step-by-step explanation:

This is using the independent probability

Are events M and event N independent. No, because P(M)·P(N) ≠ P(M ∩ N).

What do you mean by independent events?

A and B are said to be independent events if the probability of an event A occurring is unaffected by the occurrence of another event B whereas dependent events influence the probability of other events Independent events can have common outcomes.

If two events A and B are independent of each other, then A and B have equal probability of occurring as

P(A∩B) = P(A) · P(B)

Event M and N have probabilities such that P(M) = 0.4, P(N) = 0.28 , P(M∪N) = 0.56 and P(M∩N) = 0.12

P(M)·P(N) = 0.4 × 0.28 = 0.112

and P(M∩N) = 0.12 (Given)

So, P(M∩N) ≠ P(M)·P(N)

This shows that both the events are not independent events.

Therefore, Event M and N are not independent event.

Answer:

radius=3

Step-by-step explanation:

volumes of a cone = 1/3πr²h

12π = 1/3× π × r² × 4

37.7 = 12.6r²/3

cross multiply

37.7×3=12.6r²

113.1=12.6r²

make r² subject of the formula

r²=113.1÷12.6

r²=8.976

r=√8.976

r=2.996

r=3.0 (to the nearest tenth)
