Answer:
He will bake 300 loaves of bread.
Step-by-step explanation:
Paul bakes loaves of bread and bread rolls in the ratio of 2 : 5
Suppose, the number of loaves of bread he will bake [tex]=x[/tex]
Given that, he bakes 750 bread rolls.
So, according to the given ratio, we will get......
[tex]\frac{loaves\ of\ bread}{bread\ rolls}=\frac{2}{5}\\ \\ \frac{x}{750}=\frac{2}{5}\\ \\ 5x=1500\ [by\ cross\ multiplication]\\ \\ x=\frac{1500}{5}\\ \\ x=300[/tex]
So, he will bake 300 loaves of bread.

If there are 52 cards in a deck what is the probability of drawing two cards, and getting a king both times?
There are two cases here:
Case 1: First card chosen is a queen
452∗351=1221452∗351=1221Case 2: First card chosen is not a queen.
4852∗451=162214852∗451=16221Adding both the cases, we get 1722117221 = 452452 = 113113
In a simpler case: Think about it this way: Shuffle a deck of cards randomly. The probability of drawing a queen as your second card is the same as the probability that the second card in the deck is a queen, which is clearly 4/52.
(06.02)A six-sided number cube labeled 1 through 6 is rolled 500 times. An odd number is rolled 325 times. Compare the experimental probability of rolling an odd number with the theoretical probability of rolling an odd number and select one of the statements below that best describes the situation.
The experimental probability and theoretical probability are the same.
The experimental probability is larger than the theoretical probability.
The experimental probability is smaller than the theoretical probability.
There is not enough information to determine the relative frequency.
Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
Number of times a die rolled = 500
Number of times an odd number occurs =325
so, the experimental probability would be
[tex]\dfrac{325}{500}\\\\=0.65[/tex]
And we know that
Number of outcomes in a die = 3
Number of total outcomes = 6
So, The theoretical probability would be
[tex]\dfrac{3}{6}=\dfrac{1}{2}=0.5[/tex]
So, The experimental probability is larger than the theoretical probability.
Hence, Second option is correct.
Which of the following statements is true? A 15 kg box has more inertia than a 10 kg box. Forces occur in equal and opposite force pairs. Objects in motion will keep moving at the same velocity unless acted upon by an outside force. All of the above.
Answer:
All of the above
Step-by-step explanation:
A 15 kg box has more inertia than a 10 kg box. --TRUE
Inertia is a property of matter related to its mass. The more mass an object has, the greater its inertia. S o the statement is correct since 15 kg is greater in mass than 10 kg therefore it has more inertia.
Forces occur in equal and opposite force pairs. -- TRUE
This statement is correct and is known as Newton's third law. Which tells us that for every force of action there is a reaction force that is equal in magnitude but opposite in direction.
Objects in motion will keep moving at the same velocity unless acted upon by an outside force. -- TRUE
This is Newton's first law of motion, it tells us that an object will retain its state of rest or movement as long as there is no resulting force or external force acting on it.

B) It is a function because weekend packages are always $50 more than weekday packages.
C) It is not a function because each package number has two different prices.
D) It is not a function because there are two different packages available for $180.
Option: C is the correct answer.
C) It is not a function because each package number has two different prices.
Step-by-step explanation:Function--
Function is a mapping from a set A to set B such that each element of set A is mapped to a unique number.
i.e. every element has a single image.
Here a package number has two different rates or prices.
(Since let set A is package number and set B is a price of the package. )
As element of set A has more than one image.
Hence, it is not a function.

Which point is a reflection of point R (-2, 9) first across the y-axis and then across the x-axis?
A : (-9, -2)
B: (-2,-9,)
C: (2, -9)
D: (9, -2)
Final answer:
Explaining how to find the reflection of a point across the y-axis and then the x-axis that is option C is correct.
Explanation:
To find the reflection of point R(-2, 9) first across the y-axis and then across the x-axis, we apply the transformations for each axis separately. When reflecting across the y-axis, the x-coordinate changes sign, making it (-2, -9). Then, reflecting across the x-axis changes the sign of the y-coordinate, resulting in the final reflection at point (2, -9).
If i= √-1 what is the value of i^3
Final answer:
To calculate i^3, we use the powers of i, where i = √-1. We find that i² = -1, and thus i³ = i² × i = -1 × i = -i.
Explanation:
The value of i to the power of 3, denoted as i3, can be determined by understanding the fundamental properties of the imaginary unit i, where i is defined as i = √-1. To find i3, we start by considering the powers of i:
i1 = i,
i2 = -1,
i3 = i2 × i = -1 × i = -i,
i4 = (i2)2 = (-1)2 = 1.
Therefore, the value of i3 is -i.

What are the solutions of the system? y=6x+6y=−x2+5x+6
Answer:
Given the system of equations:
[tex]y = 6x+6[/tex] .....[1]
[tex]y = -x^2+5x+6[/tex] .....[2]
Equate these two equations we have;
[tex]-x^2+5x+6 = 6x+6[/tex]
Subtract 6 from both sides we have;
[tex]-x^2+5x= 6x[/tex]
Subtract 6x from both sides we have;
[tex]-x^2-x= 0[/tex]
⇒[tex]-x(x+1) = 0[/tex]
By zero product property we have;
⇒x = 0 and x+1= 0
⇒x = 0 and x=-1
Substitute these values in [1] we have;
For x = 0
y = 6(0)+6 = 6
for x = -1
y =6(-1)+6 = -6+6= 0
Therefore, the solutions of the given systems are, (0, 6) and (-1, 0)
The scatterplot below shows a set of data points.
Which point would be considered an outlier?
(1, 5)
(3, 9)
(5, 4)
(9, 1)
Answer:
Step-by-step explanation:
Definition of an outlier:
A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.
Here in the scatter plot we can see that
(3,9) deviates from other values very much.
Outlier An extreme value in a set of data which is much higher or lower than the other numbers. Outliers are to be removed to get accurate results since they have the power to affect the mean value of the data but have little effect on the median or mode of a given set of data.
That is why when outliers are present mean or mode is the better mode to measure central tendency.

Katrin’s monthly payment for electricity went down from £38.60 to £34.20 she thinks this means that her monthly payment has gone by 1/6. Is katrin correct? Show how you think this?
Katrin's claim about her monthly payment going down by 1/6 is incorrect.
Explanation:To determine if Katrin's monthly payment has gone down by 1/6, we need to compare the difference between her old monthly payment (£38.60) and new monthly payment (£34.20) with 1/6 of her old monthly payment. Taking 1/6 of £38.60, we get £6.43.
The actual difference between her old and new monthly payment is £38.60 - £34.20 = £4.40. This difference is not equal to £6.43, so Katrin's claim is incorrect.
Therefore, Katrin's monthly payment has not gone down by 1/6.

Catherine finds that in a randomly selected sample of 500 families in her home town, 45% own at least one computer. Her research shows that there are a total of 35,000 families in her town.
Which statements are true? Select EACH correct answer.
A If she collected data for a random sample of 1000 families in her home town, then that percentage would be a better estimate for the percentage of all 35,000 families that own a computer.
B Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer.
C To estimate the percentage well, she would need to collect data for all 35,000 families.
D Since her sample was only 500 families, it is not possible that the percentage is a good estimate for the percentage of all 35,000 families that own a computer.
Statements A and B are true
Let's analyze each statement based on statistical principles:
A: This statement is true. Increasing the sample size to 1,000 families would yield a better estimate of the true proportion of families owning at least one computer. A larger sample size reduces the margin of error, making the estimate more precise.B: This statement is true. Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer. Random sampling helps in representing the population accurately.C: This statement is false. Collecting data from all 35,000 families, though more accurate, is impractical and unnecessary. A well-conducted survey with a good sample size can provide a reliable estimate.D: This statement is false. Even though the sample size is 500 families, it can still provide a reasonable estimate for the percentage of families owning a computer if randomly selected.Conclusion
Statements A and B are correct, as they follow good statistical sampling practices. Statements C and D are not accurate in the context of the given scenario.
