Pirya needs 1 1/2 cups of raspberries for 3/4 of a cake, so she needs 1 1/2 * (4/3) = 2 cups of raspberries for the whole cake.
What is fraction?A fraction is a numerical representation of a portion of a total. It consists of two integers, a numerator and a denominator, separated by a line or slash. The numerator reflects the number of equal portions of the whole that are being considered, while the denominator represents the total number of equal parts in the whole. For instance, the fraction "1/2" denotes one of two identical pieces, or half, of the whole. Mathematicians frequently utilize fractions to represent quantities, ratios, and proportions. They are also used in everyday life to signify amounts, such as one-half of a pizza or one-third of a cups of sugar.

PLEASE ANSWER FAST y-1/6=15/18
Question regarding Modulus attached below.
Answer:
x=4/3, 8/3
Step-by-step explanation:
We will solve this in two steps, one where the right hand side is 2, one where it is -2. This is because the equation is satisfied either way when [tex]|6-3x|[/tex] is equal to either of those values.
Let's start with 2. We have [tex]6-3x=2[/tex]. Subtracting 6 from both sides and then dividing by 3 gives us that x = 4/3. This is the first value.
Now, we solve for when it equals -2. We have [tex]6-3x=-2[/tex]. Subtracting 6 from both sides and then dividing by 3 gives us that x = 8/3. This is the second value.

What is the sampling method that involves taking a random selection of people from a defined population?.
Simple random sampling is a sort of probability sampling in which a selection of participants is randomly chosen from a population by the researcher.
What is Probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x.
The probability of an event can be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
In order to better grasp probability, let's look at a straightforward application.
Let's say we need to forecast if it will rain or not. Either "Yes" or "No" is the appropriate response to this query.
There is a chance that it will rain or not. Here, probability can be used. Using probability, one may forecast the results of a coin toss, a roll of the dice, or a card draw.
Hence, In probability sampling, a sample is chosen from a population based on the randomization principle, also known as chance or random selection.

do you think it makes sense to use the statistician's model to predict the calories in food items from the fast food restaurant quiteaburger? explain why or why not.
The statistician model makes sense to predict the calories in food items.
What is statistician's model ?A mathematical model called a statistical model contains a collection of statistical presumptions about how sample data are produced (and similar data from a larger population). A statistical model simulates the process of creating data, frequently in a highly idealised form.
Yes it makes sense to use the statistician model to predict calories calories in food items because the test of the overall model I.e F test is significant at any level of significance because the p value (2.2 e^-16) is approximately zero which indicates that the model Is significant.
And also the individual test of each variable are all significant at any significance level (alpha) with p values ( 2e^-16, 2e^-16, 1.36e^-6).
Thirdly we can say of the strength of the relationship between calories and the independent variable through the R value = √R square = √0.929 = 0.9638 which indicates a strong relationship between them.

A toy jeep i 12 and 1/2 inche long while an actual jeep meaure 18 3/ 4 feet long what i the value of the ratio length of the toy jeep to the length of the actual Jeep what doe thi ratio mean in the ituation?
Therefore the solution of this question is ratio length = every 1 inch of toy car represents 1.5 feet of actual car
What is ratio?In mathematics, a ratio shows how two numbers are multiplied together. In a bowl of fruit, for instance, the proportion of oranges to lemons is eight to six if there are eight oranges and six lemons. Lemons to oranges are divided 6:8 and oranges to all other fruits are divided 8:14 in a similar fashion.
Here,
A toy Jeep measures 12 1/2 inches.
Before calculating the ratio, let's first convert each size into the same unit of measure and decimal points:
=>12 ½ = 25/2
=> 12.5 inches;
=> 18 ¾ = 75/4
=> 18.75 feet .
The actual length of a jeep is 18.75 feet.
The ratio can now be determined by converting feet to inches.
1 inch of a toy car equals 1.5 feet of an actual car because
=> 1 foot = 12 inches
=> 12.5 inches : 225 inches
=> 225 / 12.5
=> 18 inches
Therefore, every 1 inch of toy car represents 1.5 feet of actual car.

the answer is -x+8 but I don't get why its +8 and not -8
Your first step of simplifying is to distribute the "–" or "–1" in front of the second set of parentheses through that second set of parentheses. The –1 must be distributed to every term in the second set:
[tex]\begin{aligned}(4x^2-5x)-(4x^2-4x-8)&=(4x^2-5x)\boldsymbol{{}-1}(4x^2-4x-8)\\[0.5em]&=4x^2-5x\boldsymbol{{}-1(4x^2)-1(-4x)-1(-8)}\\[0.5em]&=4x^2-5x\boldsymbol{{}-4x^2+4x+8}\\[0.5em]&=-x+8\\\end{aligned}[/tex]

What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time.
Let the number of days to repay after a down payment be x and the y represent the total payment.
Therefore 61+24x= y equation 1
105+ 20x = y equation 2
subtract equation 1 from 2
105-61+20x-24x= 0
44-4x= 0
4x = 44
divide both sides by 4
x= 44/4

You receive paychecks every two weeks. Your first paycheck is for $217. The second is for $258. The third is for $229. What is the combined value of these three paychecks?
Answer:
The combined value is $704
If you want the average pay as well it is about $235
Step-by-step explanation:
The problem asks for the combined value of the three paychecks. So all you have to do is add them to get 704.
I found the average value by adding them to 704 then dividing it by 3. The 3 came from the amount of values we have which is 3 paychecks. So we divide the total cost by 3 to get 235.

a.) y = -6x - 47
b.) y = x/6 - 8/3
What is Equation of line ?
A straight line's general equation is y = mx + b, where m denotes the gradient and y = b denotes the point at which the line crosses the y-axis. On the y-axis, this value b is referred to as the intercept.
We know, slope-intercept form is
y = mx + b
The given equation is in point slope form,
a.) y + 5 = -6 (x + 7)
b.) y + 2 = 1/6 (x-4)
Now, let's write each equation in slope-intercept form,
a.) y + 5 = -6 (x + 7)
y + 5 = -6x - 42
y = -6x - 42 - 5
y = -6x - 47 [which is slope-intercept form]
b.) y + 2 = 1/6 (x-4)
y + 2 = 1/6 * x - 1/6 * 4
y + 2 = x/6 - 2/3
y = x/6 - 2/3 - 2
y = x/6 - [2/3 + 2]
y = x/6 - [(2 + 6) / 3 ]
y = x/6 - 8/3 [which is slope-intercept form]

Find the x-intercept of the line 5x + 17y = -25
x - intercept =
Find the y-intercept of the line 6x - 7y = -21
y - intercept =
Answer: To find the x-intercept of a line, we set y equal to 0 and solve for x. To find the y-intercept of a line, we set x equal to 0 and solve for y.
For the line 5x + 17y = -25, we set y equal to 0 to find the x-intercept:
0 + 17y = -25
17y = -25
y = -25/17
Since we set y equal to 0, the x-intercept is (0, 0).
For the line 6x - 7y = -21, we set x equal to 0 to find the y-intercept:
6x - 7y = -21
-7y = -21
y = 21/7
Since we set x equal to 0, the y-intercept is (0, 21/7).
Therefore, the x-intercept of the line 5x + 17y = -25 is (0, 0) and the y-intercept of the line 6x - 7y = -21 is (0, 21/7).
