Math question someone pls explain how to answer it I am stuck pt.2

Answer:

0.25

Step-by-step explanation:

If the person made it 105 out of 140 times, that can be written as a fraction: 105/140

Then, you just turn the fraction into a decimal by dividing the numerator by the denominator.

105 divided by 140 = 0.75

0.75 is the probability that it does hit the board, so we can subtract 0.1-0.75 to give us the probability that is doesn't hit the board. This would give us 0.25

Hope this helps

The experimental probability that the player does not hit the dartboard is,

⇒ 1 / 14

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times.

Hence, Number of not hit dartboard is,

⇒ 140 - 105

⇒ 35

Thus, The experimental probability that the player does not hit the dartboard is,

⇒ 35 / 140

⇒ 7 / 28

⇒ 1 / 14

To solve this linear equation, we can re arrange the numbers.

Q) (0.35 + 5.2) x = 27.75

Ans. x (0.35 + 5.2) = 27.75

        0.35x + 5.2x = 27.75

        5.55x = 27.75

        x = 27.75/5.55 = 5

        x = 5

Answer:B

Step-by-step explanation:

Substitute!

3(4)+4=8 is incorrect because 3x4=12 and 12+4 doesn't equal 8

2(4)+8=40 is incorrect. 2x4 is 8. 8+8 doesn't equal 40

4(4)+4=12. is incorrect 4x4= 16. 16+4 doesn't equal 12

Therefore 5(4)-2 is correct. 5x4 is 20 and 20-2 is 18

Answer:

Beth's class left for the field trip at 7:13 A.M..

Step-by-step explanation:

To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.

The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.

To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.

9:41 A.M. minus 55 minutes is 8:46 A.M..

8:46 A.M. minus 93 minutes is 7:13 A.M..

Therefore, Beth's class left for the field trip at 7:13 A.M..

I hope that helps!

Answer:

6:59am

Step-by-step explanation:

1 hour and 33 minutes = 93 minutes

55 minute ride to museum

93+55=148

60 minutes in 1 hour

148 divided by 60 = 2 hours 46 minutes

Time Left: 9:41

9.41-2.46

6.59

They left at 6:59am

The angle measures of J and L are given as follows:

m < J = m < L = 65º.

To obtain the angle measures, we must considering that the sum of the measures of the internal angles of a triangle is of 180º.

The internal angles for this problem are given as follows:

Angles J and L are congruent, meaning that they have the same measure, which is obtained as follows:

50 + x + x = 180

2x = 130

x = 65º.

Answer:

3 and 4 are the only true statements.

Step-by-step explanation:

1 is incorrect because the experimental probability is calculated by dividing 24 by 150, which gives us 0.16 or 16%, not 0.15 or 15%.

2 is wrong because 6 ÷ 150= 0.04, giving each number a 4% chance of occurrence.

3 is correct because Karl occurs 28 of the 150 times. 28 ÷ 150= 0.1866666666666667, which is 18.66666666666667%, or about 19%.

4 is also correct because the theoretical probability of each name is 25.

5 is false because the experimental probability of Martin, Paxton, and Sal were less than the theoretical probability.

1.25 + 1.25 = 2.5

Therefore, the graph that goes from 0, to day one at 2.5.

Answer:

C

Step-by-step explanation:

develop an equation

If a dog eats 1.25 cup twice a day:

1.25 x 2 = 2.50

We have the average per day

Y = 2.50x

X represents days

Y = 2.50 x 1

Y = 2.50

We have are coordinate

X = 1

Y = 2.5

( 1 , 2.5 )

Graph C follows that equation and coordinates.

Therefore the answer is C

The probabilities are given as follows:

The probabilities are the same, as the number of cards with G is the same number of cards with O.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

For this problem, we have that the parameters are given as follows:

Hence the probability, which is equals for both cases, is obtained as follows:

p = 3/4 x 3/4

p = 9/16.

Answer:

For a second I thought your birthday was today haha.

Let's begin by creating an equation to reflect the supplied data.

Let x represent my current age.

We are aware of the following:

4/5 x > 3/4 (x + 1)

When both sides are multiplied by 20 (the least common multiple of 5 and 4) the result is:

16x > 15(x + 1)

When the right side is expanded, the following results:

16x > 15x + 15

Subtraction of 15x from both sides results in:

x > 15

My age cannot be less than 16 since it must be an integer number of years.

As a result, the answer is 16.

Answer:

3 hours

Step-by-step explanation:

We can use ratios to solve

30 km         45 km

---------   = ---------------

2 hours        x hours

Using cross products

30 * x = 2 * 45

30x = 90

Divide each side by 30

30x/30 = 90/30

x = 3

The constant of proportionality is the one in option B; k = 95

Remember that a proportional relation can be written as:

y = k*x

Where k is the constant of proportionality.

Here we can define the variables:

x= months.

y= total revenue.

Now we can use any pair of values in the table to get the constant of proportionality. For example if we use the first pair we get:

x = 2

y = 190

Replacing these values we will get:

190 = k*2

190/2 = k

95 = k

That is the constant of proportionality, the correct option is B.
