Alia and her husband have a list of six names for their new baby boy. Each name is equally likely to be picked. They make the table to assign each name a number, then they roll a die 150 times. The results are in the table. Select all the true statements.
Answers
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.

(0.35 + 5.2) x. =27.75
Answers
First, we need to perform the addition inside the parentheses:
5.55 x = 27.75
Next, we can solve for x by dividing both sides of the equation by 5.55:
x = 5
Therefore, the value of x that makes the equation (0.35 + 5.2) x = 27.75 true is 5.
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

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times. Using the results of the simulation, what is the experimental probability that the player does not hit the dartboard? Express your answer as a decimal.
Can someone please help me i am so confused.
Answers
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
What is mean by Probability?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

Which of the following represents the constant of proportionality in the table below?
Answers
The constant of proportionality is the one in option B; k = 95
Which is the constant of proportionality?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.

Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.
Answers
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:

Step-by-step explanation:
1 hour and 33 minutes = 93 minutes
