soy de Argentina,salu2 C':
Answer:
55
Step-by-step explanation:
Set up an equation first like this,
5x=275
you would set it up like this because she needs $275 and she saves her money for a _____ amount of weeks that's why I said x, we want to know the number of weeks. So you would divide 275 by 5 and you get 55. So she will need to save up for 55 weeks.

Noah bought 4 tacos and paid $6. At this rate, how many tacos could he buy for $15? Jada's family bought 50 tacos for a party and paid $72. Were Jada's tacos the same price as Noah's tacos?
Answer:
-Noah could buy 10 tacos for $15.
-Jada's tacos were not the same price as Noah's tacos.
Step-by-step explanation:
You can use a rule of three to find the amount of tacos that Noah could buy with $15:
$6 → 4
$15 → x
x=(15*4)/6=10
At this rate, Noah could buy 10 tacos for $15.
Now, to find out if Jada's tacos were the same price as Noah's tacos, you have to find the price per taco in each case by dividing the amount paid by the number of tacos bought:
Noah: 15/10=1.5
Jada: 72/50=1.44
According to this, Jada's tacos were not the same price as Noah's tacos.
What is the Z-score for Paula if she got 1400 on the SAT, the mean was 1100 and the standard deviation was 275? step by step how to get +1.09
get marked the brainliest
mu = 1100 = population mean
sigma = 275 = population standard deviation
x = 1400 = raw score
z = z score
z = (x-mu)/sigma
z = (1400-1100)/(275)
z = 300/275
z = 1.0909090909091 approximately
z = 1.09
Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).
The positive z score is due to Paula's raw score being above the mean.

five less than three times a number is 1. What is the number?
Answer: 3 times a number can be written as 3x.
Five less than 3x means you must subtract 5 from 3x.
the word "is" means equals,
so 3x-5=10
Step-by-step explanation:
since it is given that 3 times a number less than five is 1
since it is given that 3 times a number less than five is 1 getting equation:- 3x-5=1
since it is given that 3 times a number less than five is 1 getting equation:- 3x-5=1 x=6/3
since it is given that 3 times a number less than five is 1 getting equation:- 3x-5=1 x=6/3 x=2

Using the graph below, calculate the average rate of change for f(x) from x = 0 to x=2.
a: x=-4
b: x=-2
c: x= 2
d: x= 4
Answer:
Option (D)
Step-by-step explanation:
Formula to get the average rate of change of the function f(x) between two points x = a and b is,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
We have to calculate the average rate of change between x = 0 and x = 2.
From the graph attached,
f(0) = -2
f(2) = 6
Therefore, average rate of change = [tex]\frac{6-(-2)}{2-0}[/tex]
= [tex]\frac{8}{2}[/tex]
= 4
Option (D) will be the correct option.

The principal of a large high school wants to learn about student opinion regarding remote learning versus in person learning. Each of the following methods introduces a possible source of bias. Name the type of bias . a. The principle selects a random sample of students from those who signed up for remote learning. b. The student emails a random sample of 100 students, but only 28 students respond . c. The principal surveys the first 50 students that submit their learning preference for the upcoming school year.
Answer:
Step-by-step explanation:
the students that are in the survey are in it because they like the subject, rather than picking students from both types of groups, the ones that aren't doing remote learning and the ones that are doing remote learning.
Bias occurs when a particular portion of the population is given more weight or have a higher priority during sample selection which in turn affects the outcome and result of our result as it won't be representative of the population. The type of bias introduced in the scenarios above are :
Selection bias Non - response bias Undercoverage biasSelection bias occurs when only a particular faction of the population is used rather than the entire population during sample selection. Rather than making selection from the entire students, only those who signed for remote learning were sampled.
Non - response bias occurs when a large portion of the selected sample fail to participate in a survey. With only 28% response and 72% non - responsive. Non - response bias has creeped in.
Undercoverage bias is usually associated with convenience sampling as the selection made might fail to randomly cover the entire population.
Hence, selection, non - response and Undercoverage bias are present in the selection made by the principal.

In a full set of permanent teeth, 1/4 of the teeth are incisors, 1/4 are premolars, and 3/8 are molars. What fraction of all the teeth are incisors, premolars, and molars
Answer:
7/8
Step-by-step explanation:
In a full set of permanent teeth, 1/4 of the teeth are incisors, 1/4 are premolars, and 3/8 are molars. What fraction of all the teeth are incisors, premolars, and molars?
To solve the above, we add all the fractions together.
= Incisors + Premolars + Molars
= 3/8 + 1/4 + 1/4
Least Common Denominator = 8
= (3 × 1 + 2× 1 + 2 × 1)/8
= 3 + 2 + 2/8
= 7/8
Hence, the fraction of all the teeth are incisors, premolars, and molars is 7/8

You started a savings account with $125. Every month, you deposit $55 into your savings account. What is the linear equation that represents this relationship? y=55x−125y is equal to 55 x minus 125 y=125x+55y is equal to 125 x plus 55 y=55x+125y is equal to 55 x plus 125 y=125x−55
Answer:
Step-by-step explanation:
Given Initial deposit = $125
If each moth $55 is being deposit, the balance each month will form an AP as shown;
125, 180, 235...
The nth term of the AP is expressed as;
y = a + (x-1)d
a is the first term = 125
d is the common difference = 180- 125 = 235-180 = 55
Substitute
y = 125 + (x-1)55
y =125+55x-55
y = 70+55x
y = 55x + 70

What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
It is given that:
The complex numbers are:
z = 1 - 2i and w = -3 + 5i
z + w = 1 - 2i - 3 + 5i
z + w = -2 + 3i
z - w = 1 - 2i + 3 - 5i
z - w = 4 - 7i
w - z = 4 + 7i
Thus, the answers would be z + w = -2 + 3i, z - w = 4 - 7i, and w - z = 4 + 7i after adding and subtracting two complex numbers.

In the figure above, lines l and m are parallel and lines s and t are parallel if the measure of <1 is 35, what is the measure of 2
Answer: 145
Step-by-step explanation:
145 degrees
The measure of angle ∠2 in the triangle is 145.
Option D is the correct answer.
We have,
From the figure,
The s and t lines are parallel.
The l and m lines are parallel.
Now,
∠1 and ∠a are corresponding angles.
∠b and ∠a are corresponding angles.
This means,
∠1 = ∠a = ∠b = 35
Now,
∠2 and ∠b add up to a straight angle.
This means,
∠2 + ∠b = 180
∠2 + 35 = 180
∠2 = 180 - 35
∠2 = 145
Thus,
The measure of angle ∠2 is 145.

Simon wants to build a cube-shaped storage container that holds 125 cubic feet of water for some frogs he recently purchased.Using the formula, V=s3, where represents the volume of the container and represents its side length, find the length of one side of the container.
Answer:
Length of one side of the container = 5 feet
Step-by-step explanation:
Given:
V = s³
Where,
V = volume of the container
s = side length of the container
V = 125 cubic feet
Find s?
V = s³
125 = s³
Find the cube root of both sides
3√125 = 3√s³
5 = s
s = 5 feet
Length of one side of the container = 5 feet

i think u want the definition of relation
A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation. A function is a type of relation.
Step-by-step explanation:
plssssssssssss markkkk meee brainlist
A relation is a collection of Ordered pairs where each x-value is paired with only one y-value.
What do you mean by domain and range of a function?
For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of x for which [y] exists.
Given is the graph of a equation
A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x, y) is in the relation.
