The statement about probability that is correct would be that the probability of landing on yellow is less than the probability of landing on blue. That is option B.

Probability is defined as the total number of possible outcome of an event.

The repeated colour which are numbered from 1 to 8 are as follows:

Therefore, the probability of landing on yellow is less than the probability of landing on blue because 1/4 is less than 3/8.

#SPJ1

Answer: B: The probability of landing on yellow is less than the probability of landing on blue.

Step-by-step explanation:

The experimental probability farthest from the theoretical probability is P(greater than 8). The theoretical probability of rolling a 9 is 1/12 because there is one 9 out of twelve total possible outcomes.

Experimental probability refers to the probability of an event based on data acquired from repeated trials or experiments.

Theoretical probability is the probability of an event occurring based on logical reasoning or prior knowledge. In Todd’s case, he rolled a 12-sided die marked with the numbers 1 to 12.

The probabilities are as follows:P(odd number) = 18/48P(greater than 8) = 16/48P(9) = 12/48To answer the questions:1. Which experimental probability matches the theoretical probability exactly?The theoretical probability of rolling an odd number is 6/12 or 1/2 because there are six odd numbers out of the twelve total possible outcomes.

The experimental probability Todd obtained was 18/48. Simplifying 18/48 to lowest terms gives 3/8, which is equal to 1/2, the theoretical probability.

Therefore, the experimental probability that matches the theoretical probability exactly is P(odd number).2. Which experimental probability is farthest from the theoretical probability? The theoretical probability of rolling a number greater than 8 is 3/12 or 1/4 because there are three numbers greater than 8 out of twelve total possible outcomes.

The experimental probability Todd obtained was 16/48. Simplifying 16/48 to lowest terms gives 1/3, which is not equal to 1/4, the theoretical probability.

The experimental probability Todd obtained was 12/48. Simplifying 12/48 to lowest terms gives 1/4, which is not equal to 1/12, the theoretical probability.

However, the difference between the experimental probability and the theoretical probability for P(9) is smaller than that of P(greater than 8). Therefore, P(greater than 8) is the experimental probability that is farthest from the theoretical probability.

There is approximately an 89.44% probability that a box of cereal is underfilled by 5 g or more.

To find the probability that a box of cereal is underfilled by 5 g or more, we need to calculate the probability of obtaining a weight measurement below 345 g.

First, we can standardize the problem by using the z-score formula:

z = (x - μ) / σ

Where:

x = the weight value we want to find the probability for (345 g in this case)

μ = the mean weight (350 g)

σ = the standard deviation (4 g)

Substituting the values into the formula:

z = (345 - 350) / 4 = -1.25

Next, we can find the probability associated with this z-score using a standard normal distribution table or a statistical calculator.

The probability of obtaining a z-score less than -1.25 is approximately 0.1056.

However, we are interested in the probability of underfilling by 5 g or more, which means we need to find the complement of this probability.

The probability of underfilling by 5 g or more is 1 - 0.1056 = 0.8944, or approximately 89.44%.

Therefore, there is approximately an 89.44% probability that a box of cereal is underfilled by 5 g or more.

Answer: y = -1/4x +5 (option A)

Step-by-step explanation:

you should substitute the point in the equation so, you have to use "+c" instead of the "-3". the equation you have to use is y = -1/4x + c

(4,4)

y = -1/4x + c

4 = -1/4(4) + c

4 = -1 + c

4+1=c

c = 5

So the -3 in the equation should be replaced with 5 in the equation and that's the parallel line passing through the point (4,4)

therefore the equation is -   y = -1/4x +5

The unknown number that is summed with 3 and double whose result is one less that the number would be = -7

To determine the unknown number, let the unknown number be = n

From the question statement;

2(n + 3) = n-1

2n + 6 = n-1

Bring the like terms together;

2n-n = -6-1

n = -7

Answer: CORRECT

Step-by-step explanation: Because any negative number will be positive when multiplied together but since there are 3 negative number the 3rd negative will always negate the positive so therefore Delila is correct

She is correct.

A odd number is 1 less or one greater than an even no. so when we multiply negative nos. odd no. of time we will have only one no. remaining to be multiplied and the rest of the nos. will be paired and we know a pair of negative nos. multiplied together is positive then multiplying it with one more negative no. will make the whole thing negative.

According to the given question

Delila is multiplying three negative numbers and determines that the solution will be negative.

When we multiply negative numbers odd number of times we get the result in negative and when we multiply negative numbers even number of times the obtained result is positive.

CAN SOMEONE ACTUALLY SOLVE IT PLEASE

Step-by-step explanation:

Answer: -3/7

Step-by-step explanation:

The first step is to find the slope of the line

y = mx + c where m is the slope of the line
Rearrange the equation and we get

3y = 7x + 7
y = 7x/3 + 7/3

So the slope of the line 7x - 3y = -7 is 7/3

There is another rule that states: The product of the slopes of two lines perpendicular to each other is -1

So, the slope of the line perpendicular to 7x - 3y = -7 is -1/(7/3) = -3/7

Answer:

x = 17°

Two ways to solve:

     Since the 130° angle is on a straight line, 180°, we can do the following:

180° - 130° = 50°

     Then, a triangle's angles add up to 180

180° - 50° - 113° = x

17° = x

x = 17°

--------------------------------------

     The exterior angle is equal to the two opposite interior angles added together,

130° = x + 113°

17° = x

x = 17°

Answer:

(x + 1)² + y² = 3

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (- 1, 0 ) and r = \(\sqrt{3}\) , then

(x - (- 1) )² + (y - 0)² = (\(\sqrt{3}\) )² , that is

(x + 1)² + y² = 3

The z-score for the price of the family's home can be calculated as follows:

z = (350,000 - 375,000) / 7,500 = -3.333

A negative z-score indicates that the value is below the mean. Therefore, the price the family paid for their home is lower than the average price of homes in their neighborhood, so it can be considered unusual.

So, the answer is: The z-score is -3.333 and it is unusual.

Answer:

-18

Step-by-step explanation:

So we have the expression:

Multiply:

\(=(-6)-12\)

Subtract:

\(=-18\)

Answer:

-18

Step-by-step explanation:

We are given the expression:

\(a-6y\)

and asked to evaluate when a= -6 and y=2.

Therefore, we must substitute -6 in for a and 2 in for y.

\(a-6y , a=-6, y=2\)

\((-6)-6(2)\)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition, and Subtraction.

Multiply 6 and 2.

\((-6)-(6*2)\)

\((-6)-(12)\)

\((-6)-12\)

Subtract 12 from -6.

\((-6-12)\)

\(-18\)

The expression a-6y when evaluated for a=-6 and y=2 is equal to -18.

clerk A and clerk B can simultaneously stock a shelf in 180/13 minutes

Step-by-step explanation:

Let the first clerk be A and the second clerk be B

A can stock a shelf in 20 min

B can stock a shelf in 45 min

Consider the complete work to be W

A’s rate of stocking =  per minute

B’s rate of stocking =  per minute

When, A and B work simultaneously, rate of work done =

Total work done simulatenously =  180/13

Therefore, clerk A and clerk B can simultaneously stock a shelf in 180/13  minutes

Answer:

Step-by-step explanation:

The rate of each clerk is 1/25 and 1/45 respectively so together they can stock the shelf

t/25+t/45=1 (the least common multiple of 25 and 45 is 225)

t/25(9/9)+t/45(5/5)=1

(9t+5t)/225=1

9t+5t=225

14t=225

t=225/14 min

t=16 minutes (rounded to nearest minute)

TJohn's age is approximately 23.33 years, and Sharon's age is approximately 93.33 years.

And the correct graph is D.

To represent the given problem as a system of equations, we can use the following information:

John is 70 years younger than Sharon: j = s - 70

Sharon is 4 times as old as John: s = 4j

Let's plot the graph for this system of equations:

First, let's solve equation (2) for s:

s = 4j

Now substitute this value of s in equation (1):

j = s - 70

j = 4j - 70

3j = 70

j = 70/3

Substitute the value of j back into equation (2) to find s:

s = 4j

s = 4(70/3)

s = 280/3

The solution to the system of equations is j = 70/3 and s = 280/3

In the graph d, the solution to the system of equations is represented by the point (70/3, 280/3), which is approximately (23.33, 93.33) on the graph.

Therefore, John's age is approximately 23.33 years, and Sharon's age is approximately 93.33 years.
