A recipe for banana bread uses 4 cups of bananas for every 8 cups of flour. How many cups of bananas are needed when 2 cups of flour are used?.

Answer:

Step-by-step explanation:

The scatter plot shows positive correlation because as the plotted values of x increase, the values of y generally increase.

When x and y both increase, you have a positive correlation. When one increases and the other decreases then you have a negative correlation.

If a square has an area of 450 square inches then according to Area = 2(length of a side), the length of one side of that square will be 225 inches.

The formula of Area of a Square is ,

area = side × side = side² square units

whereas the perimeter of square is = 4 x side

A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at right angles or at 90 degrees.

let the length of a side of a square is x

area of square is = 450 square inches

as area of square is found as

Area = 2(length of a side)

2x = 450 square inches

x =450/2

x=225 inches

so the length of each side of square is 225 inches.

The value of the unknown side y for the given triangle will be 46.15.

In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

The sine law, also known as the law of sines, states that the ratio of a triangle's side length to the sine of its opposite angle is constant for all three sides. It's sometimes referred to as the sine rule.

We have to find the value of the side as y.

Apply Sin law in the given triangle,

SinA/a=SinB/b=SinC/c

Sin42/31=sin85/y

0.6691/31=0.9962/y

y=30.8822/0.6691

y=46.15

Thus, the value of the unknown side y for the given triangle will be 46.15.

△X'Y'Z' is transformed form △XYZ. If △XYZ rotated 90 degrees counterclockwise about the origin, then YZ ⊥ Y'Z'. Hence option B is the correct option.

What is transformation?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Given that,

△XYZ is rotated 90 degrees counterclockwise about the origin to form △X'Y'Z'.

Each side of △XYZ is rotated 90 degrees counterclockwise.

Then the angle between corresponding sides of △XYZ and △X'Y'Z' are 90 degrees.

Therefore

Answer: A

Step-by-step explanation: To solve this problem, we can set up a system of equations to represent the information given in the problem. Let x represent the cost of a plate of spring rolls, y represent the cost of a plate of chicken tenders, and z represent the cost of a plate of pretzel dippers.

The first group spent $23 on 2 plates of chicken tenders and 1 plate of pretzel dippers, so the equation for this group is:

2y + z = $23

The second group spent $30.75 to buy 3 plates of spring rolls and 1 plate of chicken tenders, so the equation for this group is:

3x + y = $30.75

The third group spent $22.25 on one of each appetizer, so the equation for this group is:

x + y + z = $22.25

Now that we have three equations, we can use algebraic techniques to solve for the value of x, which represents the cost of a plate of spring rolls.

First, we can solve the second equation for y:

y = $30.75 - 3x

Substituting this expression for y into the first equation, we get:

2($30.75 - 3x) + z = $23

Solving for x, we find that x = $7.75.

Therefore, the cost of a plate of spring rolls is $7.75, so the answer is A.

The probability distribution that she or he is on duty on Saturday or Sunday will be 0.7

What is probability distribution ?

A frequency distribution that has been idealised is a probability distribution.

An individual sample or dataset is described by its frequency distribution. It's the number of times in the dataset that each potential value of a variable appears.

The probability of occurrence of a value determines how frequently it appears in a sample. Probability is a value between 0 and 1 that indicates the likelihood that something will happen:

A value will occur more frequently in a sample the higher its likelihood.

The probability of a value is more particularly the relative frequency in an indefinitely large sample.

Probability distributions are theoretical since it is not feasible to obtain infinitely large samples in practise.

Let the people work on Sunday = sun = 4

Let the people work on Saturday = sat = 3

total no. of doctors are 10

so the probability distribution of people work on either Sunday or Saturday will be :

= Sun + sat / total no of doctors

y=1/3x+4 is the equation of line passing through (3, 5) and parallel to -x+3y=6

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

-x+3y=6

3y=6+x

Divide both sides by 3

y=2+1/3x

y=1/3x+2

slope is 1/3

In parallel lines the slope will remain same

The equation for the line connecting the two points is as follows y = 2x + x.

A mathematical statement known as an equation is comprised of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Equation of a line:

y = mx +b

Where;

m = slope

b = y-intercept

You are given the y-intercept from the point (0,2). When x = 0, y = 1

You can then see from the Eq: y = mx + b  

that b = 1

By dividing the change in y by the change in x, or "rise over run," one may get the slope, m.

m = (y1-y2)/(x1-x2)

One of the points is (x1, y1) and the other (x2, y2)

m = (1-(2)) / (0 -(2))

m = (-1)/(-2) = 1/2

Using the Central Limit Theorem for proportions, the correct option is:

E. The statistic is biased.

What is Central Limit Theorem?

The central limit theorem in probability theory proves that, even if independent random variables are not normally distributed in themselves, in many cases, when they are added together, their properly normalised sum tends toward a normal distribution.

The central limit theorem states that the distribution of the sample means will be roughly normally distributed if you have a population with mean and standard deviation and take sufficiently large random samples from the population with replacement.

The Central Limit Theorem establishes that for a proportion p in a sample of size n:

- The expected value is[tex]$\mu=p$[/tex].

- The standard error is [tex]$s=\sqrt{\frac{p(1-p)}{n}}$[/tex]

In this problem, the expected value is different of the expected of [tex]$\mu=p$[/tex], hence, the statistic is biased, and the correct option is [tex]$\mathbf{E}$[/tex].

Following is the geometric progression of Nelson's debt after each month: (E) 950,967.1, 984.51, 1002.23, 1020.27

A geometric progression sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

So, in this issue, the interest rate is as follows: 1.8%.

The debt will therefore be equal to the debt from the previous month multiplied by 100 + 1.8 = 101.8% = 1.018 each month, and the common ratio is as follows: 1.018.

In light of this, the terms of the series are as follows:

2nd term: 950 x 1.018 = $967.1

3rd term: 967.1 x 1.018 = $984.51

4th term: 984.51 x 1.018 = $1002.23

5th term: 1002.23 x 1.018 = $1020.27
