Answer:

Yes. Both ratios can be reduced down to 1/2.

Step-by-step explanation:

Hope it helps!

For two numbers to be proportional, they need to be directly increasing or decreasing in a constant ratio.

To simplify these ratios, we can use division.

So, 7: 14 simplified is 1: 2.

So, 4: 8 simplified is 1: 2.

If these ratios are both simplified to equal 1 :2, they are proportional.

The correct answer is the signs for r and b are the same (+ or ). The slope b and the correlation r don't necessarily have the same values, but they always share the same sign.

The idea employed in the issue is

1.Correlation

2.Regression

Correlation: Correlation analysis is used to gauge how strongly two variables are related. The symbol for the correlation coefficient is r.

Shape: Whether the data points follow a linear pattern or some other complex curves is indicated by the association's form. If it seems that a line would adequately summarise the overall trend in the data, then do so. The relationship between the two variables is then linear.

The appropriate statement can be found below:

The determination of the standard deviation between the two variables influences how a least-squares linear regression function slopes, and in a similar way, how the sample correlation coefficients are interpreted.

By examining the sign of the regression slope and the correlation coefficient, which depend on the standard deviation between the two variables, the proper conclusion can be drawn.

The standard normal distribution is a normal distribution of standardized values called z-scores.

A z-score is measured in units of the standard deviation. If a random variable is normally distributed and follows the parameters mean (mu) and standard deviation (sigma), the z-score is calculated as the difference between the value of the random variable and the mean divided by the standard deviation . The cumulative distribution function (CDF) of a standard normal variable is used to find the fraction of scores that lies between two given values. To determine the fraction of scores, one can use the CDF to find the area under the standard normal distribution curve between the given values.

Given the above Trigonometric expressions,

1) θ = 35°

2) θ =62°

3) θ = 90-y°

Trigonometric functions are real functions in mathematics that connect an angle of a right-angled triangle to ratios of two side lengths. They are widely utilized in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many more.

There are six expressions of an angle that are often used in trigonometry. Their names and acronyms include

For A)

Sin(55) = cos (θ)

sin (55)= sin(90-θ)

Compare both sides

55 = 90 - θ

θ = 90 - 55

θ = 35°

For B)

Sin(θ) = Cos (28)

angle θ would be  Arc sin (cos (28))

Thus,

θ =  62°

For C)

Cos(y) = sin (θ)

Angle θ = arc sin ( cos (y) )

Thus,

θ = 90 - y

What is a fraction ?

In Maths, a fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator.

Given :

water bottle : 56 ounces of water

1 cup = 8 fluid ounces

Cups that holds 56 ounces of water = 56/8 [Since, 1 cup = 8 fluid ounces]

Cups that holds 56 ounces of water = 7

Cups that holds 56 ounces of water = cups that water bottle can hold

Thus , cups that water bottle can hold  = 7

The probability of eating both poisoned apples if you randomly eat 3 out of the five apples without replacement is 1/10 or 0.1.

To calculate this probability, we use the formula for combinations of n objects taken r at a time, (nCr) which is equal to n!/r!(n-r)!. In this example, n = 5 and r = 3, so the formula reduces to 5!/3!(5-3)! = (5*4*3)/(3*2*1) = 10. This means that there are 10 different combinations of 3 apples, out of the five, that can be chosen. Since only two of the apples are poisoned, the probability of eating both of the poisoned apples is 2/10 or 0.1.

The youngest child is Jade.

The expression that represents Jane's age is 2n.

The oldest child is Jem.

Jade is 12 years old

The equation that represents the sum of ages is 5n - 5 = 55.

Jade's age = n

Jane's age = 2 x n = 2n

Jem's age = 2n - 5

Sum of the ages:

n + 2n + 2n - 5 = 55

5n - 5 = 55

Jade's age can be determined using the above equation:

5n = 55 + 5

5n = 60

n = 60 / 5

n = 12

To determine Jane and Jem's age, substitute for n in the equation that represents their ages.

Jane's age = 2 x 12 = 24

Jem's age = 2(12) - 5

= 24 - 5

Answer:

So, the solution is x = -3 and y = 4. This means that the two lines intersect at the point (-3, 4)

Step-by-step explanation:

The given equations represent two lines in a two-dimensional plane. To find the solution for the values of x and y that satisfy both equations, we can use the method of substitution or elimination.

Using substitution, we can solve for x or y in one of the equations and substitute the result into the other equation. Let's solve for y in the second equation:

x + y = 1

y = -x + 1

Now, substitute this expression for y into the first equation:

-x + (-x + 1) = 7

-2x + 1 = 7

-2x = 6

x = -3

Finally, we can use the expression for y that we derived earlier to find y:

y = -x + 1 = -(-3) + 1 = 4

Answer:

(1, - 1.5 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then

midpoint = ( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

here (x₁, y₁ ) = (4, 0 ) and (x₂, y₂ ) = (- 2, - 3 ) , then

midpoint = ( [tex]\frac{4-2}{2}[/tex] , [tex]\frac{0-3}{2}[/tex] ) = ( [tex]\frac{2}{2}[/tex] , [tex]\frac{-3}{2}[/tex] ) = (1, - 1.5 )

(1, -1.5).

Step-by-step explanation:

The midpoint of a segment with endpoints (x1, y1) and (x2, y2) is given by the following formula:

((x1 + x2)/2, (y1 + y2)/2)

So, for the given endpoints (4,0) and (-2,-3), the midpoint is:

((4 + (-2))/2, (0 + (-3))/2) = (1, -1.5)

The midpoint of the segment is (1, -1.5).

Let A1,A2,A3,A4 be the 4 A.M.s between 4 and 19.

Then,

An=a+(n−1)d

a6=19=4+(6−1)d

Or d = 3 ...... (i)

Now,

A1=a+d=+3=7

A2=A1+d=7+3=10

A3=A2+d=10+3=13

A4=A3+d=13+3=16

The 4 A.M.s between 4 and 19 are 7, 10, 13, 16.

The sampling method used in this data collection is cluster sampling. Cluster sampling is a probability sampling technique that divides the population into separate groups or clusters and randomly selects a number of those clusters to be included in the sample. In this case, the population would be the students in the algebra class, and the clusters would be the individual students. Using a simple random sampling technique, the interviewer would select a certain number of students from the class and ask them how many pairs of jeans they own. The average number of pairs of jeans owned by the students in the sample would then be calculated by adding together the number of jeans owned by all of the students in the sample, and then dividing by the number of students in the sample.

Average number of pairs of jeans owned by students in sample = (Sum of jeans owned by all students in sample) / (Number of students in sample)
