Answer:9-4=5  5+4=9

Step-by-step explanation:

The intersection and the union of the intervals (-7, 0) and (-3, 5) are (-3,0) and (-7,5) respectively

Given,

The intervals = (-7,0) and (-3,5)

Draw the intersection and union of the intervals in the number line

The intersection is an interval that lies within the both intervals (-7,0) and (-3,5)

Intersection of the intervals (-7,0) and (-3,5)  = (-3,0)

The union is the set that consist of all the elements in the first interval and all the elements in the second interval

Union of the intervals (-7,0) and (-3,5) = (-7,5)

Hence, The intersection and the union of the intervals (-7, 0) and (-3, 5) are (-3,0) and (-7,5) respectively

If the distribution is skewed right, the mean is greater than the median.

A distribution is said to be skewed right if more than half the area under the distribution curve is to the right of the mode of the distribution. Also the tail of the distribution will be longer on the right side. In this case, the distribution is said to be positively skewed.

Then the mean of the distribution will be greater than the median of the distribution.

i.e., mean > median

Likewise, the distribution is said to skewed left if more than half of the area under the distribution curve is on the left side.

Also if a distribution is not skewed, then it is said to be symmetric.

y=3

Step-by-step explanation:

2x-y=1

if x=2 then

2(2)-y=1

4-y=1

y= 4-1

y=3.

Answer:

y = 3

Step-by-step explanation:

2x - y = 1 ← substitute x = 2 into the equation

2(2) - y = 1

4 - y = 1 ( subtract 4 from both sides )

- y = - 3 ( multiply both sides by - 1 )

Answer: y = [tex]\frac{1}{2}[/tex]x + 4

Step-by-step explanation:

       First, let us graph the points to see patterns. See attached.

     This function is linear, so we can write an equation in slope-intercept form. m is the slope and b is the intercept.

      We can find the slope with rise over run. Starting at point (0, 4) and counting up one and over 2 to (2, 5).

y = mx + b

Correct answer is B. The value of tan²(e)+1 is sec²(e).

Triangle side length ratios are known as trigonometric ratios. In trigonometry, these ratios show how the ratio of a right triangle's sides to each angle. Sine, cosine, and tangent ratios are the three fundamental trigonometric ratios.

In geometric figures, unknown angles and distances are derived from known or measured angles using trigonometric functions. The necessity to calculate angles and distances in disciplines like astronomy, mapmaking, surveying, and artillery range finding led to the development of trigonometry.

As t varies inversely with n , we can use coordinate pair function model.

The inversely proportional property state that two values are opposite to each other. If there will increase in one value or quantity then the another quantity will automatically decrease with the same ratio or different and if one quantity will decrease then another will increase with that ratio.

Say if x and y are inversely proportional, then mathematically

x ∝ 1 / y

The factors of the expression are (2b+10) and (2b-10).

A factor in mathematics is an integer that evenly divides another number by itself, leaving no remainder.

We can employ a variety of techniques, including the division method and the multiplication method, to determine the factors of a number.

Factors of an algebraic expression is calculated by factoring the given expression into smaller algebraic expressions.

Now let us factor the given expression.

4 b²-100

This expression can be written in the form of the difference of two squares.

(2b)²-(10)²

We know that (a²-b²) can be factored into (a+b) and (a-b).

So the expression (2b)²-(10)² can be factored into (2b+10) and (2b-10).

Therefore the factors of (4 b²-100) are  (2b+10) and (2b-10).

An equation which is the best model for a line of fit for the given data is y = 3/4x + 5.

A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two variables, with the resulting points showing any association (correlation) between the data set.

A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.

By critically observing the graph (see attachment) which models the data in the table above, we can logically deduce that an equation for the line of best fit is given by y = 3.7x + 0.3.

In conclusion, an equation which is the best model for a line of fit for the data is y = 3/4x + 5.

 The percentage is a mathematical operation that is expressed with the symbol "%" is a relationship that allows us to know the portion of an initial value to represent a set.

  It could also be defined as a representation of an original value that lets us know a certain number of elements that we want from that original value or set.

 To solve this problem, we use a simple rule of three to find the percentage value of the sample.

289 -------- 100%

273 ---------  x

x = (273 * 100%) / 289

x = 94.46%

A right triangle is a three-sided polygon. For right triangles, the sum of the square of the two sides is equal the square of the longest side. The sum of the angles in a right triangle is 180 degrees of which one of the angles measure 90 degrees.

According of the Pythagorean Theorem, a triangle is a right triangle if the sum of the square of the two sides is equal the square of the longest side.

The Pythagorean Theorem: a² + b² = c²

Where:

Total amount of money in the account in the second bank after 3 years will be represented by the function: P[tex]e^{0.0747}[/tex].

The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously after t years is-

A = P[tex]e^{rt}[/tex]

Here, we are given that there are 2 financial institutions-

1st financial institution:

interest rate =  3% for the first year

and interest rate for next two years = 2%

2nd Financial institution:

interest rate = 2.49% for three years

Let the principal amount deposited be P

We assume that the interest is compounded continuously.

Then for the 2nd bank-

Amount = P[tex]e^{rt}[/tex]

here, r = 2.49%

= 0.0249

Amount = P[tex]e^{0.0249 * 3}[/tex]

= P[tex]e^{0.0747}[/tex]

Thus, the total amount of money in the account in the second bank after 3 years will be given by the function- P[tex]e^{0.0747}[/tex].

Answer:

a punch recipe calls for one and 12 quarts of sparkling water

Step-by-step explanation:

Answer:

Sparkling water: 50 quarts

Grape Juice: 25 quarts

Step-by-step explanation:

The punch recipe uses 1 1/2 quarts of water and 3/4 quarts of grape juice

That would make a total of

1 1/2 + 3/4 = 3/2 + 3/4 = 6/4 + 3/4 = 9/4 quarts of punch

Therefore to make 75 quarts, we have to figure out how many of 9/4 quarts would be needed.

This is 75 ÷9/4

Dividing by 9/4 is same as multiplying by 4/9

75 ÷9/4 = 75 x 4/9 = 300/9 = 100/3

So we will need 100/3 times as much of both ingredients

For sparkling water this would be

1 1/2 x 100/3 = 3/2 x 100/3 = 300/6 = 50 quarts

For grape juice we will need
3/4 x 100/3 = 300/12 = 25 quarts
(Or we can subtract 50 from 75 to get 25 quarts)

The power of quotients will be the law that would be used to simplify the expression. The correct option is B.
