The student initially had 42 ounces of rice, bought 58 more for a total of 100 ounces. These were divided into 10 portions, so each portion will contain 10 ounces of rice.
Explanation:This problem is a basic arithmetic question. The student starts with 42 ounces of rice and then adds 58 more ounces, for a total of 100 ounces. She then divides these 100 ounces into 10 equal portions. The key here is to understand the concept of division, which basically means splitting up a total amount (100 ounces) evenly into a certain number of parts (10 portions). To do this, simply use the operation of division: 100 divided by 10 equals 10. Thus, each portion will contain 10 ounces of rice.

Use the spinner shown. it is equally probable that the pointer will land on any one of the six regions. if the pointer lands on a borderline, spin again. if the pointer is spun twice, find the probability that it will land on grey and then purple
The probability of a spinner with six equally probable outcomes landing on specific colors in sequence (grey then purple) is 1/36 since the events are independent. Their individual probabilities (each 1/6) are multiplied to find the combined probability.
Explanation:The question involves a topic in probability called independent events. In this case, the spinner landing on grey in the first spin and purple in the second spin are independent events. That means, the outcome of the first event does not affect the outcome of the second event and vice versa.
Since the spinner has six regions, and landing on any one of them is equally probable, the probability of landing on grey (or any specific color) in one spin is 1/6. Similarly, the probability of landing on purple in one spin is also 1/6.
Since these events are independent, the probability of both these events happening in sequence can be found by multiplying the probabilities of each individual event happening. So, the probability of the spinner landing on grey in the first spin and then on purple in the second is (1/6)*(1/6) = 1/36.

The probability of landing on the grey region first and then the purple region is 1/18.
Explanation:The question asks for the probability of landing on the grey region first, and then the purple region on a spinner. To find the probability, we first need to determine the total number of possible outcomes. Since the spinner has six regions, we have six possible outcomes on the first spin. If the spinner lands on a borderline, we spin again. So, on the second spin, we also have six possible outcomes. Since each spin is equally likely, the total number of possible outcomes is 6 x 6 = 36.
Next, we need to determine the number of favorable outcomes, which is the number of ways we can land on the grey region first and then the purple region. From the spinner, we can see that there are two grey regions and one purple region. So, the number of favourable outcomes is 2 x 1 = 2.
Finally, we can calculate the probability by dividing the number of favourable outcomes by the total number of outcomes: 2/36 = 1/18. Therefore, the probability of landing on the grey region first and then the purple region is 1/18.

The length of the major axis of the ellipse below is 14, and the length of the red line segment is 3. how long is the blue line segment?
The length of the blue line segment is 11 units.
What is relation between sum of the distance of a point from the focus of ellipse and the length of major axis?For any point P on an ellipse, the sum of the distances from P to the two foci is equal to the length of the major axis of the ellipse. This is known as the "distance property" of an ellipse.
To see why this is true, consider an ellipse with foci F₁ and F₂ and major axis length 2a. Let P be any point on the ellipse, and let D₁ and D₂ be the distances from P to F₁ and F₂, respectively. Then, by definition of an ellipse, we know that:
D₁+ D₂ = 2a
Given that,
Two line segments
Red segments of length = 3 unit
So from the definition we know that,
The sum of segments = the length of major axis
The length of major axis = 2a
2a = D₁+ D₂
14= 3 + D₂
D₂ = 11
Therefore, the length of the blue line segment is 11 units.

A store sells 48 count packages of Snickers candy bars for $27.50 per package, and 36 count packages of KitKat bars for $21.50 per package. Mrs. Sweettooth bought total of 204 Snickers and KitKat bars in the store and paid $119.50. How many of each candy bars did she buy?
To find out how many Snickers and KitKat bars Mrs. Sweettooth bought, we can solve a system of equations using the count and cost information.
Explanation:Let's assume that Mrs. Sweettooth bought x packages of Snickers and y packages of KitKat bars.
From the given information, we can set up two equations:
48x + 36y = 204 (equation 1) - representing the total count of candy bars27.50x + 21.50y = 119.50 (equation 2) - representing the total cost of the candy barsTo solve this system of equations, we can use a method called substitution:
Rearrange equation 1 to solve for x: x = (204 - 36y)/48Substitute the value of x in equation 2: 27.50[(204 - 36y)/48] + 21.50y = 119.50Simplify and solve for yOnce y is found, substitute its value back into equation 1 to find the value of xBy solving this system of equations, we can determine the number of Snickers and KitKat bars that Mrs. Sweettooth bought.

To find the best predicted value of female attractiveness rating for a male rating of 5, substitute '5' for 'x' in the given regression equation, then calculate the result.
Explanation:In your given problem you have mentioned a linear regression equation, modifyingabove y with caretyequals=8.128.12negative 0.323−0.323x, that was derived from paired attractiveness ratings of males and females from 50 speed dates. The male attractiveness rating is your independent variable x and the female attractiveness rating is your dependent variable y.
You are asked to calculate the predicted female attractiveness rating if a male rates a female as 5 (x equals 5). To do this, you need to substitute x with 5 in the regression equation, which leads to the following calculation:
modifyingabove y with caret = 8.12 - 0.323 * 5.
By calculating this equation, you get the best predicted value of modifyingabove y with caret (attractiveness rating by female of male).
